Are you doing your best work? ‘Doing more with less’ is one of those business sayings which is just part of our working lives. A phrase which drives us to think about how we can be more efficient, quicker, faster, smaller, lighter or cheaper than our competitors.

In our world, energy efficiency has always been important. The drive to use less energy while still keeping people or products at the right temperature is near the top of every customer’s agenda. Price is probably top of that list of items that must be lower than before.

However, driving cost out of a solution can often come at the price of quality, if you are not careful. Installing a project more cheaply can be good in the short term. However, upfront savings can be lost with long-term maintenance or operational costs on a system installed in haste.

Doing more with less is fine, as long as you can demonstrate that your solution will, in fact, save more over its lifetime than what it is replacing.

Johnson Controls and Hitachi sign global HVAC venture agreement

Johnson Controls and Hitachi recently signed a global joint venture agreement at the World Economic Forum in Davos.

The agreement is designed to provide a wide range of heating, ventilation, air conditioning and refrigeration solutions. Johnson Controls now owns 60% of Hitachi Appliances which has a $2.6 billion air conditioning business, not including its sales and service business in Japan.

The joint venture makes available a range of VRF (variable refrigerant fl ow) solutions, room air conditioners and absorption chillers, in addition to the current Johnson Controls products.

The deal will be fi nished later in 2015 once the companies receive regulatory approvals.

“The joint venture will propel us forward with superior products, enabling Johnson Controls to deliver the most diverse technology portfolio in the industry to meet customer demands across the changing global marketplace,” said Johnson Controls Chairman and CEO, Alex Molinaroli.

Beijer Ref in DX Distribution Deal with CarrierSwedish air conditioning and refrigeration wholesalers, Beijer Ref, has announced an exclusive deal with Carrier to distribute the HVAC manufacturer’s direct expansion (DX) products across the EU.

The deal excludes countries in the European Union where Carrier already has a DX distributor. Beijer Ref will be using its European branch network to market the products.

Per Bertland, Beijer Ref’s CEO said,“With this exclusive distribution agreement and the relaunch

of Carrier’s products, Beijer Ref strengthens its position as a leading refrigeration & air conditioning wholesaler in Europe. It enables us to off er our customers an even stronger product supply. This collaboration agreement is yet another example of the benefi t of Carrier’s relationship with the Beijer Ref Group.”

Thermo King Expands Worldwide Dealership NetworkTemperature controlled transport solutions expert, Thermo King, expanded its dealership with nine new sales and service dealerships, and 17 main service locations, the company has announced.

The new dealerships are in Russia, Kyrgyzstan, Bosnia/Herzegovina and Slovenia, with new service locations in Sweden and Turkey. Thermo King has also grown its presence in Africa with new dealerships in Tanzania, Uganda and Zambia.

Thermo King’s Dwight Gibson, said,“Our goal is to provide customers with the best sales and

service network in the industry. Our dealers have an unequalled level of expertise and can provide solutions to customers’ needs from more than 500 locations across 75 countries in the EMEA [Europe, Middle East and Africa] region.”

The new additions to the network mean the business now has over 500 locations in 75 countries throughout EMEA.

Customers locate dealerships through their dedicated website: http://europe.thermoking.com/dealer-service-network.html

Daikin Buys Refrigerant Manufacturer SolvayDaikin has bought the Belgian refrigerant manufacturer Solvay with the aim of ‘fully entering’ the market in Europe.

In addition, the purchase will help Daikin to widen its product range to include automotive refrigerants and is aiming to make global sales worth 30 billion yen (~£171.2 million) by 2018.

Daikin already has a range of fl uorinated gases which are made in its French subsidiary.

Daikin is hoping that buying Solvay will help it get closer to European car manufacturers. Solvay turns over around 10 billion euros a year and sells around 53 million euros of refrigerants a year.

Findings in MonacoFrigesco will be presenting the latest developments on its energy saving system for refrigeration equipment to investors and policy makers at the ‘CleanEquity’ event in Monaco in early March.

Frigesco won ‘Refrigeration Product of the Year’ at the recent National ACR Awards in Birmingham for its fl ash defrost technology, which collects waste heat in retail refrigeration systems and uses it for ‘low energy defrosting’.

Frigesco recently won funding from DECC (Department of Energy and Climate Change) to develop the fl ash defrost technology to work with air source heat pumps.

Working with heat pump manufacturer Glen Dimplex in a joint venture, they will be looking at how to apply the

technology to make heat pumps an even more sustainable and effi cient solution for heating and cooling.

Refrigerant specialist A-Gas International has announced the opening of its newly named business, A-Gas Americas. The business will operate from its existing companies in Ohio, Texas and Mexico.

The new business comes together from the merger of its existing companies Coolgas, RemTec, CIJSA and A-Gas Performance Chemicals. A-Gas Americas business will continue to focus on providing refrigerants and services to the air conditioning and refrigeration industries.

Combining the businesses brings together the knowledge and expertise into one brand. Ken Logan, President of A-Gas US said:

“Work is already underway to consolidate IT, business and fi nancial systems within the one company and this will be completed soon. We see the establishment of A-Gas Americas as a stepping stone to greater growth in the Americas’ market during the years to come.”

Manor Concepts Gains Third ISO Certifi cation for its Environmental Management SystemsRefrigerated cabinet and retail refrigeration unit door maker, Manor Concepts, has gained its ‘ISO 14001 Environmental Management System’ certifi cation, for both parts of its company. The ISO certifi cation is the third ISOQAR accreditation in under a year.

The ISO14001 focuses on a company’s environmental management processes such as how it uses resources, manages recycling and its waste management. In February, Manor Concepts gained its 2014ISO 9001:2008 and BS OHSAS 18001 certifi cations.

“These accreditations will help to effi ciently drive the businesses forward, benefi ting not only both the companies, but also their customers too,” said operations director, Martin Corken. Corken highlighted that the certifi cation has helped them to reduce their costs by better using their resources.

Michael Tucker, managing director, concluded:“Our customers, based in the retail marketplace, have a responsibility

to monitor their impact on the environment very carefully. ISO 14001 guarantees that the products they are purchasing from us are manufactured by an environmentally responsible business which has demonstrated a commitment to continuous environmental improvement.”

B&ES Releases Business Manifesto Ahead of General ElectionThe Building & Engineering Services Association (B&ES) launched its ‘Business Manifesto’ has launched to highlight how it is going to tackle challenges in the construction market up to 2020.

The manifesto, purposefully published ahead of the country’s general election in May this year, focuses on three issues, namely procurement and payment, skills and training, and sustainability.

Andy Sneyd, President of the B&ES (pictured), said at the briefi ng,

“The Business Manifesto is focused to a great extent on the iniquity of late payment, the elimination of waste from the procurement process, and the maximisation of effi ciency throughout the supply chain.”

He continued,“But, it also highlights the growing importance of vocational

education and training to ensure we employ the required calibre, and the required number, of highly skilled and highly motivated individuals.”

Andy went on to highlight that the B&ES is working on developing new qualifi cations and standards for the industry too.

“There is no doubt that these news standards will have a signifi cant impact on every organisation and individual engaged in building engineering services – and the shape and structure of the sector as a whole,” he added.

Wolseley UK and Pipe Center open new distribution centrePipe Center has offi cially opened its Measham distribution centre (DC) in Derbyshire - the newest and most technologically advanced distribution facility in Wolseley UK’s supply chain.

The 142,000 sq. ft. facility has given Pipe Center the ability to deliver across its entire network on a next-day basis and created 54 new job opportunities.

Measham features cutting edge technology such as a dynamic “goods to man” Kasto automated tube storage system. The bespoke Kasto system, which required the installation of 182 Drive Piles,* has boosted storage capacity by 20% and reduced the distance warehouse operatives have to travel when picking.

HighJump™, a leading warehouse management system, processes all warehouse tasks and off ers superior tracking and traceability of inventory, further maximising effi ciencies and reducing costs. Narrow aisle trucks work directly with HighJump and forklift trucks and their operators are automatically directed to the correct location.

Andy Wighton, Managing Director, Pipe and Climate Center said: “We have created one of the most dynamic and advanced distribution centres in the industry that will help us achieve customer service excellence”.

F Gas Implementation in 2015

Many readers will have been aware of a recent Consultation on enforcement of the new F Gas

Regulations issued by DEFRA late in 2015. ACRIB has of course responded to the consultation formally on behalf of the trade associations and professional institutes that it represents. With a number of qualifying comments, ACRIB broadly accepted the proposals and our responses were endorsed by AREA and CIBSE.

The consultation clearly stated that its scope did not include the content of the Regulations itself but simply provided a mechanism for the continued enforcement of these requirements by the current team within the Environment Agency. The lead team within the Environment Agency have been very active in the industry since the new EU Regulations were published in mid 2015, attending Conferences and providing clarifi cation on queries and responses to individual questions.

Supplementary to our formal responses to the questions posed, ACRIB also took the opportunity to reinforce the industry’s support for a mandatory, low cost National Database, similar to the ACRIB F Gas Skillcard for individual certifi cation. It is felt that this could mitigate some of the cost of compliance and assist in the enforcement process. Beyond this, we did not consider it necessary to challenge the enforcement resource or procedures, as there is real evidence to suggest that, combined with the UK industry’s responsible approach to the F Gas Regulation, these have been eff ective in helping to reduce emissions and support compliance.

In addition it should be noted that the new F Gas Regulation includes additional obligations and penalties that will support improved compliance, with stronger obligations relating to both the supply and purchase of F Gases, which the UK industry had identifi ed in the original EU Consultation as being desirable. Recent statistics on take up of individual and company F Gas Certifi cation support the view that compliance with this aspect of the Regulations has been given an added boost in the run up to the introduction of these new obligations from 1st January 2015. Future restrictions on the availability of Fluorinated gases under the phase down over the next few years are likely to lead to even further increases in responsible use of refrigerants by equipment owners.

This together with the newly published range of guidance notes provided by DEFRA , and regular contact between DEFRA, EA and ACRIB industry representatives, mean that the UK is well placed to see further reductions in emissions going forward.

Ben Bartle-Ross, Technical Trainer

A real opportunity for fridge engineers

As a trainer, I have the privilege of meeting many engineers in both the aircon and the heating

industries. I’ve noticed a slow increase in cross fertilisation from these two distinct but vital parts of the building services industry.

In France, the same engineer will often turn up to fi t or service your aircon or your heating so it has always amused me that here in the UK, the two disciplines are sometimes seen as separate alien entities.

There are distinct qualifi cations needed for both, of course. But, that got me thinking about the business opportunities that F-Gas qualifi ed engineers in particular may be missing out on.

As a heat pump manufacturer, we have seen a healthy growth in overall sales of our Ecodan heating system and the majority of these involve sealed, monobloc units, which can be fi tted by an MCS-qualifi ed engineer, but do not need F-Gas qualifi cations.

We are also seeing growth in sales of split heat pump systems, and although the numbers are smaller than the monobloc sector, split systems do off er more fl exibility in design and install which is ideal for older properties in particular.

When you consider how many older buildings we have here in the UK, the numbers and opportunities are phenomenal.

So there is a ready market for renewable heating that taps into the skills required for F-Gas – something all aircon engineers should of course have.

Heat pumps are increasingly being seen as a viable way of heating our businesses and homes, and this is being spurred by incentives such as the Renewable Heat Incentive, which shortens the payback period for customers.

So why hasn’t the aircon industry embraced split systems more? OK, there are diff erences between the commercial and domestic heating sectors and most aircon companies may not want to deal with ‘consumers’.

However, there are also thousands of heating installs – in homes, offi ces, factories, schools, etc, where an aircon engineer could make a real diff erence and – with relatively few F-Gas engineers targeting this sector, the market is almost wide open.

Aircon engineers are also able to off er a product that the average plumber is simply not able to, especially as split systems don’t require antifreeze.

So what are F-Gas engineers waiting for? Ben Bartle-Ross, Technical Trainer, Mitsubishi Electric.

to measure. Danfoss has developed a monitoring unit, called AK-LM 350, for installation in standard refrigeration systems.

“It serves a similar purpose as the black boxes we are familiar with from the airline industry. The AK-LM 350 records and reveals all the details of the refrigeration system’s cooling state and energy consumption,” says Peter Bjerg, the engineer behind the monitoring unit. The product was launched

into the market during the spring of 2014. He is currently working on a test system that can generate energy reports with simple diagrams that allow a layman to see whether their cooling systems are running optimally.

supermarkets that have installed the device. We know for a fact that there are major energy losses in many refrigeration systems, simply because they are incorrectly configured,” he explains.

This is because it has been difficult to correctly calculate the ideal energy consumption. You have to take measurements at various points in the system during operation, and that is very cost intensive.

“The device we have developed performs the calculations while the system is running. And the results are visible immediately. If a refrigeration technician has to make adjustments to a system, he/she can immediately see whether the result has moved in a positive or negative direction,” says Peter Bjerg. After installation, the supermarket, slaughterhouse, dairy, brewery or

hotel can quickly and easily access figures showing how efficiently the given system is operating. The result can be compared directly with other systems, so the owner can see the difference between several systems.

“Obviously, large retail chains will save a lot more than small convenience stores. But everyone will save money on their energy accounts when they get their system running more efficiently. The device will thus also reduce CO

2 emissions. It is also an ideal tool for technical departments in general who want to optimise their refrigeration plants. An advanced algorithm secures real-time measurement of the system. It is easy to compare against ideal COP (coefficient of performance) and to monitor the amount of reclaimed or wasted energy.”

International monitoring unitDanfoss has sold AK-LM 350 units to several supermarket chains around the world, including in China, Latin America, the Netherlands, Norway, Sweden, Italy and Denmark. But sales have been slow initially. “We are used to it, that it takes time to introduce a new product. The refrigeration industry is very traditional. Everything new has to be investigated and prove

its worth,” says Vice President Henrik Schurmann from Danfoss Electronic Controllers & Services.

“Using the device, you can now actually see whether you are installing a good system. This was not possible before. You can see whether a supplier is controlling their refrigeration systems as efficiently as their competitors. You can also place the device in other systems, for example, to compare Danfoss refrigeration systems with competing systems. In a nutshell, you can see what is working well, and where it is most feasible to make energy improvements for your refrigeration system,” he continues.

He highlights a case from the Netherlands, where a large supermarket chain with 1,000 supermarkets purchased four devices for four new supermarkets. They gave the four devices to four different suppliers. Each of them had to install the device in a refrigeration system of a supermarket. They were told that the supplier who installed the system with the highest efficiency would receive future orders for new build supermarkets.

Report GeneratingEngineer Peter Bjerg is confident that many more people will find the AK-LM 350 interesting, because it can produce simple and clear reports on refrigeration system energy consumption.

“If you can generate a physical report, with figures documenting the possible savings, the demand for the products will definitely increase,” he says.

Refrigeration is used widely in all sectors in the United Kingdom. Refrigeration is responsible for a large percentage of the total energy consumption of food retail stores. For hypermarkets the share of energy consumption for refrigeration varies between 25-30%. For convenience stores focused on food, this percentage can increase to over 60%.

COP (coefficient of performance) and energy efficient refrigeration are buzzwords in the refrigeration industry. COP is a key parameter and essentially indicates the relationship between the extracted heat and the amount of used electricity. The owner of a cooling system can use the COP figure to make comparisons with various other refrigeration systems. If a plant does not operate very efficiently, the owner can calculate how much extra it costs to run the ‘bad’ plant.

CONTROLS16


ACIS to the RESCUE at University of Portsmouth

The controls design and integration expertise of Airedale International have been key to the £2.25m University of Portsmouth data centre, which was completed at the end of 2013.

The cooling infrastructure at the data centre, which

encompasses Airedale chillers and precision air conditioning systems provides indirect free cooling, with direct fresh air free cooling the UPS room. The ACIS™ (Airedale Controls Integrated System) Building Management System (BMS) integrates each component of the data centre and optimises cooling performance to minimise energy consumption and maintain resilience.

ACIS™ uses industry standard protocol (including for example Modbus, BACNet, Trend and SNMP), to integrate with cooling and other building services from any manufacturer across multiple sites through a single integrated system. At the University of Portsmouth, ACIS™ integrates:• Cooling systems – Airedale

DeltaChill™ FreeCool chillers, SmartCool™ chilled water (CW) precision air conditioning (PAC) units and high density OnRak™ rear door IT cooling units

• External generator, building fresh air supply, battery and build room air conditioning units

• UPS room – UPS systems, main LV panel and power meters

• Water leak detection system• Fire suppression system including

VESDA, gas suppression and house fi re alarm The graphical, easy-to-use

software provides simple touch-screen operation and remote login

and integrates with the legacy BMS allowing visibility of data centre alarms from the main university site.

The home screen provides a quick view of the status of each element of the internal and external cooling system, power supply and fi re suppression system. By touching any area of the screen, users can access more detailed information. This makes it simple to anticipate and identify maintenance issues and also allows the fresh air supply to be shut down in the case of a fi re. The screen also shows live PUE (power usage eff ectiveness) and load data.

Operating manuals and engineers reports are also accessible via this screen, ensuring documentation is kept in a single, easy-to-access library.

OPTIMISING FREE-COOLING OPPORTUNITIESLinked to ACIS™, an Airedale sequence manager sequences the two DeltaChill™ FreeCool chillers in run standby operation. This provides n+1 redundancy on chillers. The standby chiller assists in free cooling mode, and also adjusts the supply water temperature to ensure it is above the dew point of the data centre and so prevent condensation. The secondary pumps are modulated, maximising part-load effi ciencies, to provide the correct amount of fl ow dependent on the load and to maintain air temperature in the data centre.

The dynamic chilled water temperature set point adjustment feature delivers free cooling for up to 95% of the year depending on ambient temperature. When free cooling is available, chilled water set points are maximised up to 20°C to prolong free cooling.

IN COMPLETE CONTROLACIS™ also provides 24/7 monitoring, reporting and diagnostic tools. This includes capture of live and historical energy usage allowing opportunities for energy savings to be identifi ed and system refi nement.

Under a managed service agreement, Airedale provides a round-the-clock remote monitoring service allowing Airedale to anticipate and resolve alarm situations remotely and

despatch its controls or service engineers as required.

The ACIS™ global set point adjustment feature also simplifi es management of the SmartCool™ chilled water PAC systems and OnRak™ IT cooling units by allowing the user to adjust them in one place.

When the data centre is unoccupied, the temperature is set to 27°C to maximise free cooling opportunities within ASHRAE guidelines. A bespoke feature of the system allows the set point to be overridden by a key switch to lower the temperature to a more comfortable working environment of 24°C when needed.

ACIS™ was developed by Airedale’s dedicated controls team. The British manufacturer has more than 40 years’ experience

of designing systems to meet complex cooling demands. Controls Manager, Paul Roper explains: “Behind the highly visual graphic user interface, ACIS is busy capturing huge amounts of data. Our controls software allows users to easily manipulate that data to get the best out of their systems. It allows users to fi ne tune the environment for maximum system performance and energy effi ciency but it also allows them to manage risk by giving them the tools to pre-empt and resolve issues quickly.” ACIS™ is in use in a wide range of data centre, retail and other applications and is ideal for both new build and retrofi t applications.

LEAK DETECTION18


ATEX or not ATEX? That is the question. What does ATEX mean and what are the classifi cations for equipment and systems?Does your hydrocarbon leak detector need to be ATEX approved?

What is Explosion proof?The ATEX Directives 94/9/

EC covers both Equipment and Protective Systems used in potentially explosive atmospheres or zones.

Classifi cations for the zones are as below:

Leak Detection

ZONE 0: Area in which an explosive gas ispresent under normal circumstances.

ZONE 1:Area in which an explosive gas could be present under

normal circumstances.

ZONE 2:

Area in which an explosive gas would not normally be present,

or would only be present for short periods.

Leak DetectionHYDROCARBON

All hydrocarbon refrigeration systems should comply with ATEX regulations and the equipment and systems should be designed to ensure that they are safe in explosive atmospheres.

ATEX Directive 94/9/EC covers any device that contains a potential ignition source and requiring special measures to be incorporated in its design or application to prevent ignition.

The regulations are designed• To prevent the formation of an

explosive atmosphere which may be produced or released by equipment and by protective systems themselves.

• To prevent the ignition of explosive atmospheres, taking into account

the nature of every electrical and non-electrical source of ignition.

• To halt an explosion immediately or to limit the range of explosive fl ames and pressure to a suffi cient level of safety.

The most commonly used refrigerants are • R290 ( propane , Care 40)• R1270 ( Propylene, Propane,

Care 45)• R600a ( Isobutane, Care 10)• R32 R410 a replacement

(methylene fl uoride) mildly fl ammable

• R1234ze (hydrofl uoroolefi n HFO) mildly fl ammableWhen looking for leaks on

Buildings, chillers and climate commitment THE ROAD TO EFFICIENCY AND SUSTAINABILITY

used will need to be covered by the ATEX regulations so your leak detector will have to be ATEX approved.

There are only a few ATEX approved hand held leak detectors on the market, one of which is the JAVAC Gas-Mate.

The JAVAC Gas-Mate uses a surface reaction sensor with accuracy 5 ppm (Methane) and is twice as sensitive as its other competitors.

Its intrinsically safe certifi cation means that it is designed not to have the potential to cause a spark or means to ignite a combustible gas. The only offi cial certifi cation for this within the EU is ATEX.

Although it is not written down within the regulations with respect to hand held equipment specifi cally, all leak detection must be ATEX approved as it comes within the range of equipment and protective systems.

I would suggest that you would not go looking for any explosive refrigerants with a naked fl ame nor would or should you do so with a leak detector that does not meet the minimum standards available. This being ATEX.

Another new gas on the market is “Trace-A-Gas”, an A-GAS product.

This is 95% nitrogen and 5% hydrogen and used for location of the leak. The nitrogen/ hydrogen mix is fi lled into the system and using the Gas-Mate the leak can be pin pointed even through the insulation. This 5% hydrogen mix is within the explosive range so an ATEX certifi ed leak detector will be a must.

The automotive industry is now moving over to R1234yf, a HFO Tetrafl uropropene, this is again in the mildly fl ammable group but for leak detection purposes a fully ATEX leak detector should always be used.

SO WHAT IS EXPLOSION PROOF?Flame proof/explosion proof is a totally diff erent matter. This is a piece of equipment that is designed to contain, or withstand an explosion should explosive gases enter the enclosure. Hence they are to say the least very heavy duty and almost bomb proof.

Typical (Ex) gas meter or (Ex) switch enclosureTypical (Ex) gas meter or (Ex) switch enclosure

In our industry must applications would come into Zone 2 so the hand held Gas-Mate would be suitable, if it was Zone 1 leak detectors would have to be fi xed and they would hard wired.

HC refrigerants mixed with air in a range of 2% to 10% (HC by volume in air) are potentially

fl ammable and can be ignited by naked fl ame, sparking electrical device and anything hotter than 460 Deg C.• When engineers work on a HC

system they must be aware of the potential hazards before they access the system.

• Understand all the labelling

• Know the refrigerant in the system and its potential hazardous properties.

• Perform a full risk assessment

• Use the best equipment available, ATEX approved if possible, you may only get one chance with explosive gases.If you require more information

The Crowne Plaza at Gerrards Cross is a 147-bedroomed

hotel and conference centre which has undergone a complete refurbishment, having been bought by the Cairn Hotel Group.

Specialist air conditioning contractor, Turn Key Air Conditioning Ltd, has installed a Mitsubishi Electric City Multi heat recovery system into the hotel, to off er guests the ultimate in modern complete comfort and style.

SAFETY FIRSTCurrent legislation restricts the use of refrigerants in buildings, with EN378 in particular intended to minimise possible hazards to persons, property and the environment from refrigerating systems and refrigerants.

Under EN378 legislation, which is particularly applicable for hotels, leak detection equipment must normally be provided if, in the case of R410a, a concentration of 0.44 kg/m3 refrigerant could be exceeded, if all of the refrigerant from a system were to leak into a single room.

WORKING TOGETHERTurn Key has developed an on-going relationship with The Cairn

Group since providing maintenance service and advice on the Newcastle International Hotel. Swirles and his team have extensive hotel experience and this gave the Cairn Group the confi dence to bring Turn Key in at an early part of the design process.

“We worked closely with The Cairn Group from day one to design a system that meets all requirements in terms of guest comfort, energy effi ciency and legislation,” added Swirles.

In close association with Mitsubishi Electric Value Added Reseller (VAR) PacAir, Turn Key designed the system with the minimum amount of refrigerant in each bedroom to comply with EN378.

PacAir also helped ensure that the equipment design was modular to allow the hotel to continue trading during the refurbishment and minimise the disruption to both the business and its guests. This is where the unique two-pipe, heat recovery City Multi system comes into its own, as it provides much more fl exibility of design and installation.

“Each room is fairly unique so we also had to ensure that the design was fl exible enough to cope with the diff erent sizes and layouts,” said PacAir Managing Director, Nigel Palmer.

PacAir also used its specialist knowledge of the complete Mitsubishi Electric range to advise on the installation of a Melcotel hotel control system which links each individual room to the Ving cards, so that systems will not operate when unoccupied.

The hotel has been refurbished to the highest standards. The entire project is expected to be completed in the Spring of 2015. Turn Key has also fi tted the infrastructure to the ground fl oor and designed the installation process to allow it to be completed in fi ve distinct phases to minimise disruption.

In addition to ducted fancoil units in the rooms, City Multi ceiling cassettes are being installed in all public areas, whilst Lossnay mechanical ventilations with heat recovery is being used to energy-effi ciently maximise the amount of fresh air within the building.

“When we were asked to help with this project, we saw it as ideal opportunity to design out the need for leak detection,” explained Swirles. “We are now looking at how we implement this in other situations with The Cairn Group.”

DE-HUMIDIFICATION30


Northwood is one of the few remaining fully operational

and privately owned sawmills in the South East of England and is renowned for supplying only the fi nest quality prime and character grade English and European oak.

It is imperative that the moisture level is kept low during storage, so that the timber becomes stable for the indoor environment where central heating is used. Dry wood can absorb moisture from the atmosphere, so the dehumidifi er eliminates the problem by removing moisture from the air.

On the advice of Calorex’s specialist sales team, a high capacity DH150BX dehumidifi er was specifi ed for the warehouse,

ideal for commercial premises and industrial environments.

James Burnford of Northwood Forestry explains: “Once removed from the kiln, the oak is between nine and ten per cent humidity. During storage, it must not exceed 12 per cent. The dehumidifi er from Calorex has been successfully managing the level in the fl ooring warehouse since it was installed earlier in the year.”

James adds: “The unit is simple to use – it’s literally a case of plugging it in and switching it on. It is also powerful enough to keep the entire warehouse at a constant level of humidity wherever in the building it is situated.”

A Calorex dehumidifi er off ers an effi cient and cost eff ective solution

to maintaining perfect conditions.The process of dehumidifi cation

involves moisture-laden air being drawn into a dehumidifi er where the air passes across a refrigerated coil. The air is rapidly cooled below its dew point, condensing the water vapour and recovering its latent heat energy for re-use. The cooled air is the passed across the condenser where it is reheated and returned to the served area at a lower relative humidity.

Typically, for every unit of energy that a Calorex dehumidifi er consumes, it will convert 2.5 times this amount to useable heat. The potential energy savings are huge compared to traditional heat and ventilation methods.

DATA CENTRE COOLING32

Roberto Felisi, product marketing director Thermal Management at Emerson Network Power observes that the term “cooling” is now outdated, replaced by the science of managing heat within the data centre as part of a “thermal management” process.


Over the last five years, thermal management

has joined the list of issues that data centre operators are under pressure to manage, in large part, because energy consumption is so critical to data centre efficiency. Once a simple task of flipping switches, data centre cooling has developed into a highly skilled and specialised art with the evolution of advanced technologies.

The Emerson Network Power Data Center 2025 report, (http://bit.ly/1y3z0hH) an industry wide

initiative that addressed questions about what the data centre will look like in 2025, has shown that thermal management appears, for the most part, to be meeting today’s market needs. The report also uncovered that there is a level of inertia in the industry around the topic, with many experts predicting current technologies remaining in place for the foreseeable future.

But will the current technologies meet the demands of future data centres, and will innovations in cooling methods which combine air and liquid be adopted to meet new demands?

THERMAL MANAGEMENTAfter all, as the data centre eco-system evolves, so does the need for thermal management to process and monitor more power and higher temperatures. Just a few years ago the standard working temperature of a data centre was around 22 degrees Celsius, but by today’s standards, that would be far cooler than required. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) which sets a framework for data centre operating temperatures, states that facilities should operate at a recommended temperature between 18 to 27°C, and depending on the IT equipment an even higher temperature is allowed in some cases.

Perhaps the most critical challenge that data centre managers face, however, is pressure to effectively manage the environmental impact of their operation. To address this issue, data centre managers will need to become more innovative in their approach, and processes such as adiabatic or evaporative cooling are likely to gain popularity as one of the most cost effective ways to handle thermal management.

DATA CENTRE COOLING 33


ADIABATIC COOLINGAdiabatic cooling is an ancient technique first used by the Romans that has been modernised for use in the 21st century. The 2,000 year old process was originally used to lower the temperature of a hot room by spraying water in the air or on the floor and as a result, has a cooling effect on the area as the water evaporates. In today’s adiabatic cooling systems, air from outside is brought in to the unit, passing through an adiabatic pad with cold water running through it. As the warm outside air passes through the pad, it cools down and consequently lowers the internal temperature of the data centre.

Using this method, data centre energy bills can be significantly reduced and with the cooling process amounting to a large part of a data centre running cost, it is easy to see why it is increasingly being adopted. As a result of smart adiabatic applications, new generation data centres

will have the ability to provide their customers with unrivalled benefits in terms of cost savings, reliability, and cooling availability. In fact, a freecooling chiller with an integrated adiabatic system will be able to guarantee 100 percent cooling, regardless of how critical the external environmental conditions might be. In the event of temperature peaks and cases of water shortages, the back-up compressors will be able to provide to full capacity whenever needed.

THE WAY FORWARDHowever, this method of cooling is unlikely to make traditional systems obsolete in the near future. What is more likely is that existing systems will be able to run traditional cooling in tandem with new solutions such as adiabatic freecooling chiller, Liebert® AFC or indirect evaporative freecooling solutions, Liebert® EFC. It is also likely that data centres will be able to adjust to specific requirements

and situations in order to run the optimal, most efficient cooling system – calculating the perfect balance between the local water and electricity costs. These approaches will be a significant cost saver, but may not be applicable to all kinds of data centre installations. The future in thermal management is therefore likely to be one in which hybrid models can flex to actual requirements rather than a one-size-fits-all legacy approach.

What seems clear above all else, however, is that over the next decade, the data centre will become increasingly “smart”. While the focus for reducing cooling costs will continue to be front and centre for data centre managers, so will the desire for investment in thermal management solutions. We are therefore likely to see further innovations in the cooling space as the industry battles to reduce high energy costs and more effectively manage environmental impact.

RETAIL REFRIGERATION

<title> Sainsbury’s chooses eCO2 for its Portishead store

<insert images > Sainsburys 1 & Sainsburys 2

There is increasing awareness among the major supermarket chains of the link between carbon footprint reduction and business success. Stores are responding to customer concerns about the way in which food reaches their shopping baskets and are looking at better ways to make their businesses more environmentally friendly.NATURAL REFRIGERANT ECO2This has been highlighted by Sainsbury’s decision to choose the new CO2 natural refrigerant from A-Gas for its £15 million store at Portishead near Bristol. eCO2 is the fi rst high specifi cation Carbon Dioxide (R744) refrigerant to be produced sustainably in the UK and is a product that can make a signifi cant diff erence in cutting a store’s carbon footprint.

eCO2 is made from waste sugar beet in the UK by the manufacturers that supply Sainsbury’s supermarkets with sugar. It has excellent thermodynamic properties, in addition to providing a green alternative to HFCs commonly used in the supermarket sector. Typically, more than 40 per cent of the average supermarket’s energy consumption is directly linked to its refrigeration systems. Natural refrigerants, like CO2, are becoming a popular option as stores look to reduce their carbon footprint.

The growth in the popularity of natural refrigerants will be further enhanced by the uncertainty for future strengthening of the F-Gas legislation in the coming years; which will see the phasing out of HFC refrigerants with a high Global Warming Potential (GWP).

SUSTAINABLY PRODUCEDSainsbury’s is looking to reduce operational Carbon emissions by 30 per cent absolute and 65 per cent relative compared to 2005; and at Portishead the supermarket group believes eCO2 is a refrigerant which can make an important contribution to this.

A-Gas Operations Manager Rob Parker said: “The X Factor for eCO2 is the sustainable way it is produced. Most CO2 refrigerants are recovered from dirty industrial processes which are far from green in their methods. eCO2 is a by-product of bioethanol production from waste sugar beet – using crops not destined for sugar production. This is a fi rst for A-Gas and the UK market, as a CO2 refrigerant produced from waste sugar beet has never been on sale before on a commercial basis.”

With its ultra-low moisture content, eCO2 has far lower moisture than competing grades of CO2 used for refrigeration. Low moisture content and high purity enable the refrigerant to work more reliably, which in turn extends the life of equipment. eCO2 can be used in a range of applications but it is particularly suitable for supermarket refrigerant systems, as its green credentials give it stand out qualities. Like traditional refrigerant grade CO2, eCO2 has a low environmental impact with zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of 1.

AT PORTISHEADThe 30,000 sq ft store at Portishead opened in October last year. It features a wide range of popular Sainsbury’s food products and a full complement of counters including the Milestone Bakery, producing fresh bread throughout the day. The store also sells electrical goods, homeware and Sainsbury’s Tu clothing line.

Two booster trans-critical CO2 packaged systems are at the heart of the store’s refrigeration systems. These multi-compressor packs each have 25kW of low temperature and 150kW of medium temperature cooling capacity. This provides the required cooling capacity for the refrigeration display cabinets and cold stores, and maintains product temperature ranges of +8°C to -18°C.

Sainsbury’s Head of Refrigeration John Skelton said: “We wanted to use eCO2 to reduce our carbon footprint. eCO2 came in a packaged format which was most convenient for the installing refrigeration contractors. The quantities and volumes made handling easy for the engineers on site. eCO2 is available from A-Gas in a range of portable cylinders for standard use, and manifold packs and Dewar cylinders for larger installations.

“One of the benefi ts of eCO2 is that it has a lower moisture content – moisture is detrimental to any refrigeration system as it damages the system internally. A supermarket refrigeration system operates 24-hours a day, 365 days a year, so it has to be extremely reliable. Having the right refrigerant plays an important part in this.”

A-Gas has also been working in partnership with Sainsbury’s to improve CO2 system performance. A-Gas has introduced a new Carbon Dioxide (R744/CO2) analysis and testing service in a move to advance the monitoring of CO2 refrigeration systems by detecting problems associated with moisture content and corrosion at an early stage.

LOOKING AHEADFollowing successful trials with Sainsbury’s, A-Gas has now extended this service to the rest of the industry. A-Gas provides customers with a suitably rated cylinder in which they can supply a liquid sample from the refrigeration system. This is returned to A-Gas where it is tested at its state of the art laboratory.

There is increasing awareness among the major supermarket chains of the link between carbon footprint reduction and business success. Stores are responding to customer concerns about the way in which food reaches their shopping baskets and are looking at better ways to make their businesses more environmentally friendly.

Sainsbury’s chooses eCO2 for its Portishead store

NATURAL REFRIGERANT ECO2Sainsbury’s has chosen the new CO2 natural refrigerant from A-Gas for its £15 million store at Portishead near Bristol. eCO2 is the fi rst high specifi cation Carbon Dioxide

(R744) refrigerant to be produced sustainably in the UK and is a product that can make a signifi cant diff erence in cutting a store’s carbon footprint.

eCO2 is made from waste sugar beet in the UK by the manufacturers

that supply Sainsbury’s supermarkets with sugar. It has excellent thermodynamic properties, in addition to providing a green alternative to HFCs commonly used in the supermarket sector. Typically, more than 40 per cent of the average supermarket’s energy consumption is directly linked to its refrigeration systems. Natural refrigerants, like CO2, are becoming a popular option as stores look to reduce their carbon footprint.

Sainsbury’s chooses eCO2 for its Portishead store

The growth in the popularity of natural refrigerants will be further enhanced by the uncertainty for future strengthening of the F-Gas legislation in the coming years; which will see the phasing out of HFC refrigerants with a high Global Warming Potential (GWP).

THE X FACTORSainsbury’s is looking to reduce operational Carbon emissions by 30 per cent absolute and 65 per cent relative compared to 2005; and at Portishead the supermarket group believes eCO2 is a refrigerant which can make an important contribution to this.

A-Gas Operations Manager Rob Parker said: “The X Factor for eCO2 is the sustainable way it is produced. Most CO2 refrigerants are recovered from dirty industrial processes which are far from green in their methods. eCO2 is a by-product of bioethanol production from waste sugar beet – using crops not destined for sugar production. This is a first for A-Gas and the UK market, as a CO2 refrigerant produced from waste sugar beet has never been on sale before on a commercial basis.”

With its ultra-low moisture content, eCO2 has far lower moisture than competing grades of CO2 used for refrigeration. Low moisture content and high purity enable the refrigerant to work more reliably, which in turn extends the life of equipment. eCO2 can be used in a range of applications but it is particularly suitable for supermarket refrigerant systems, as its green credentials give it stand out qualities. Like traditional refrigerant grade CO2, eCO2 has a low environmental impact with zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of 1.

AT PORTISHEADThe 30,000 sq ft store at Portishead opened in October last year. It features a wide range of popular Sainsbury’s food products and a full complement of counters including the Milestone Bakery, producing fresh bread throughout the day. The store also sells electrical goods, homeware and Sainsbury’s Tu clothing line.

Two booster trans-critical CO2 packaged systems are at the heart of the store’s refrigeration systems. These multi-compressor packs each have 25kW of low temperature and 150kW of medium temperature cooling capacity. This provides the required cooling capacity for the refrigeration display cabinets and cold stores, and maintains product temperature ranges of +8°C to -18°C.

ENERGY EFFICIENCY36


A detailed study of the food manufacturer’s energy

consumption indicated the potential to reduce this by over 30%. The installation of Liquid Pressure Amplifi cation (LPA), Inverter control of condenser fans and recommissioning was proposed.

The modifi cations would allow the refrigeration system to operate at low discharge pressures, often referred to as fl oating head pressure, increasing refrigeration capacity while reducing absorbed power.

LPA is installed into a manifold on the outlet from the liquid receiver; refrigerant is then pumped to the expansion valve, providing good quality liquid refrigerant during low head pressure operation. Inverter control of condenser fans provides accurate discharge pressure using the entire condenser surface area. Settings are continually adjusted in relation to external ambient temperature and refrigeration

With refrigeration consuming 40% of their electricity, a leading supplier of ethnic supermarket chilled and frozen ready meals asked Excalibur Energy for advice on improving energy e� ciency.

demand, optimising energy effi ciency for any conditions.

The design incorporates a number of features to ensure that no single point of failure could aff ect production.

An initial pilot installation was undertaken to a refrigeration pack fi tted with four Copeland reciprocating compressors operating on R404a, with a capacity of 340kW, and a 10 fan air-cooled condenser.

IMPROVEMENTS IN EFFICIENCYThe pack was monitored prior to modifi cation to establish a base line performance. Installation was completed and the monitoring repeated to show the improvements in effi ciency. An energy reduction of 36% was achieved, this represented a cost reduction of over £25,000

per year, a return on capital of less than 18 months and a 128 tonne reduction in CO

2 emissions.The success of this project

convinced the client that signifi cant cost reductions could be achieved and Excalibur were instructed to modify a further fi ve systems, which have demonstrated a similar reduction and a return on investment of less than 2 years.

Steven Pye, Operations Director at Wholesale Power UK Limited, undertook energy surveys at the sites following the modifi cations and reported that “ The sites were delighted not only with the performance and the associated reduction in consumption, costs and emissions, but also with the quality of the installations.”

ENERGY EFFICIENCY

Energy effi ciency’ is a broad term. It can include ensuring

your heating, ventilation, air conditioning or refrigeration system is working as it supposed to do, or that the cost of running it is as low as possible

Contractors, installers, specifi ers and end users are responsible for doing more with less with the systems they manage or recommend. Saving money and cutting carbon emissions are two of the main outcomes of energy effi ciency.

What are the options for being more energy effi cient?We can implement key energy effi ciency principles in the following areas:

Ways To Be More Energy E� cientPaul Singh F.Inst.R.,AIfL., LCGI, Refrigeration Training Consultant at Chillair Training Academy explains how.

‘ 1. Air Conditioning, Refrigeration, Heat Pump (ACRHP) and ancillary equipment

Manufacturers, through extensive research & development are making their ACRHP products more effi cient with each new version. They have to do this to remain competitive.

In fact, even their lean manufacturing processes use energy effi cient methodologies, right from inception through to production and delivery.

2. System design technology and control strategy

Although, we cannot get away from the basic thermodynamic principles of ACRHP, our expert system designers, through innovation, deploy and enhance these principles to bring the best out of the ACRHP equipment. These include booster systems, transcritical and sub critical systems, VRF, and ground source heat pumps to name a few.

Controls experts are using extraordinary controls and strategies that are extending parameters tremendously. They reduce the energy consumed with very much closer control to maximise equipment potential.

3. The working fl uid/s contained in the system

Research to fi nd primary and secondary refrigerants to provide

the ultimate in environmental friendliness and energy effi ciency is a constant.

Traditional refrigerants are no longer the norm. The latest HFOs and R32 represent a new era in refrigerants. Let us not forget the oils - new types and qualities are born everyday.

We even have fl uids that which engineers can inject into systems that enhance the energy effi ciency of the system.

One such fl uid is ‘IceCOLD’. It is a simple to use product that is injected into any ACRHP system (I have personally done many injections into a variety of systems) that is yielding energy effi ciency values of between 10%- 28%.

IceCOLD is an environmentally friendly synthetic catalyst that extends the lifetime of the compressor when injected into the compressor’s oil.

4. Customer training, awareness and system familiarisation

Despite having all of the above, a key factor of energy effi ciency is customer training. It is of paramount importance that we train our customers thoroughly and eff ectively in the correct handling and usage of their ACRHP systems and controls.

It is pointless to design, install and commission a very energy

39ENERGY EFFICIENCY


efficient system if we do not train the customer. A slight misuse or incorrect setting could de-value everything the aim of the project.

5. ACRHP Engineer trainingObviously, very close to my heart and something that I am passionate about. Our biggest asset is our people. It is vital to ensure that engineers receive the correct and effective training that each individual requires.

It is important that all engineers understand and deploy energy efficient technologies. Further, we need to make sure they understand the implications of their duties on energy efficiency. We need them to realise that, if they do not lag the pipework correctly they are reducing the energy efficiency of the system.

The ACRHP Industry, via the IOR is in the process of redesigning the NVQ suite of qualifications. A new era is here,

Paul Singh receives Chillair Training Academy’s Best Training Provider Award at 2015 National ACR Awards

focused on assurance that we arm our engineers with the correct knowledge, skills and competence. We will have ‘energy efficient’ ACRHP engineers.

6. The fuel used to drive the ACRHP system

Energy efficiency that drives down power usage is the ultimate aim. Different types of power generation and deliverance will soon appear. As our natural resources diminish, we need carbon free alternatives. For example, I recently heard of the ‘Organic Rankine Cycle’ being deployed using manure and slurry.

Dare I say, even new fuels are being sought (in vehicles) to drive us to the ACRHP systems on site. Bi-fuel, electric and solar to name a few.

7. Legislation & regulationThe drivers for energy efficiency, namely new legislation and regulations, are bombarding us all the time. The updated EC 517/2014 F Gas regulation in addition to the ‘ESOS’.

The ‘Energy Savings Opportunity Scheme’ is new piece of EU legislation that requires us to introduce a mandatory program of energy audits for ‘large enterprises’. This means over 9,000 of Britain’s biggest companies will be required to comply. The initial audits need to happen by 5th December 2015. You will need to comply.

Energy efficiency touches every one of us. We must question everything we do. For instance, have you ever asked yourself ‘How does what I am about to do affect energy efficiency?’

If not, then please start thinking about it, now. Moreover, you could pose that question to anyone – ‘why wouldn’t you?’

Borahurst at


In November 2014 Borahurst was awarded the installation

contract at the Reading Debenhams department store. The main air conditioning system comprised nine roof mounted air handling units, with R22 outdoor units attached to provide the heating and cooling. The task was to keep the existing AHU’s, which were still fully serviceable, but to go on and remove the R22 coils and outdoor units and then to supply and fi t new R410a replacements.

The initial work was designed and overseen by building services consultant EM Tecnica who came up with a design brief in collaboration with equipment supplier Hushon (UK) Ltd regarding suitable replacement equipment.

Following site surveys and ongoing discussions, the equipment to be changed became focused on new outdoor units manufactured by Toshiba together with new matched bespoke direct expansion heat pump coils for retro fi tting into the AHU’s, with all this equipment being supplied by Hushon (UK) Ltd.

The main focus was to carry out this work with minimal disruption to the operation of the store and the Oracle Centre. Borahurst planned the works into 3 phases ensuring only 3 AHU’s were off line at any one time (one per fl oor). At each phase it was necessary to decommission and dismantle into small sections the existing 2000kg heat pumps and casing so they could be removed from the roof, nine new 250kg cooling coils were installed in the existing air handling units both tasks

Debenhams PLC are in the process of phasing out refrigerant R22 from their stores, in line with current UK legislation

involved considerable logistical movement through the store and roof plant areas.

Forty fi ve new Toshiba heat pump condensers were installed, fi ve to each air handling unit, the electrical infrastructure and refrigeration pipework were installed before each AHU was re- commissioned enabling procedure to the next phase of the works.

The works were carried out over 12 weeks on site and successfully delivered to programme.

Clare Priest, Selling Support Manager at Debenhams Reading, provided the following testimonial:

“It was a pleasure to have Borahurst working with us. It really was as though we didn’t know they

were here. They were very respectful of our store requirements and additionally those of our shopping centre, who can be quite challenging in terms of contractor requirements. I do understand a contribution of that may have been that all of the work was carried out on the roof and did not impact sales so to speak, but it could have easily disturbed a customer entrance and the team were very understanding and did everything they could to ensure disturbances were minimal as well as leaving the site safe and clear when they were not here and physically working. Any additional requests for information or queries were welcomed and the communication

from Borahurst, throughout the project has been informative, thorough and consistent.

I would be happy to have them work with us again and trust they would deliver what they say they will”.

Introduction to R32 Suitable for: HVACR installers and consultants

Learning Objectives: Explain what HFC phase down means for HVACR industry Profile options for next generation refrigerants Describe pros and cons of R32 R32 installation and training requirements

HFC phase-down and the introduction of R32In 2015, European phase-down of HFCs has begun with the introduction of the new F-gas regulation, which will see their use reduced to 21% of average levels between 2009 and 2011 by 2030. For the HVAC-R industry, the next 15 years will see major changes, with the new legislation restricting and banning the use of refrigerant gases in certain applications.

There are a number of options for the next generation refrigerant gas, to meet future legislation and reduce the environmental impact of air conditioning, heat pumps and refrigeration. The choices are generally accepted to be R32, HFO blends, CO

2, and hydrocarbons, including R290 and R600 (similar to propane and butane).

Daikin’s preferred alternative to R410A for smaller direct expansion (DX) systems is R32 and the company is launching the first Split systems with a cooling capacity under 7kW using R32 in March 2015.

The HFC phase-down – what it means for the HVAC-R industryAlthough highly energy effi cient and the current refrigerant of choice, R410A has a high GWP of 2,088. While it will not be completely banned under the HFC phase-down, the new GWP limits, plus the fact that it represents 15% of all HFCs, means that we should start to review the use of R410A where possible.

There is a clear need to choose alternative refrigerant gases that are not only less harmful to the environment but that also meet future legislation, and are both safe and economical – in terms of existing system design and installation procedures as well as the cost of the gas itself.

Using new refrigerants that completely change system design means some systems installed over the next 5 to 10 years could become obsolete before the end of their working life. Manufacturers are acting now, introducing new products and developing ways of adapting existing systems to use

the next generation refrigerants and extend their lifespan.

The changes will mean the entire industry has to work together so that manufacturers, designers, installers and end-users are well-informed and competent in designing, specifying, installing, maintaining and using these new systems.

Next-generation refrigerant gases – what needs to be consideredThere are number of factors that need to be considered before choosing the next generation refrigerant:1. Ozone depletion potential2. Global warming potential3. Safety4. Natural resource effi ciency5. Aff ordability

1. Ozone Depletion Potential and Global Warming Potential

Ozone depletion potential must be zero, because of the global Montreal Protocol agreements and EU Ozone depleting regulations, and requires no

CONTINUING PROFESSIONAL DEVELOPMENTCONTINUING PROFESSIONAL DEVELOPMENT


further justifi cation. But Global Warming Potential (GWP) is slightly more complicated as it must be considered from an entire Life Cycle Climate Performance (LCCP) perspective.

This means that the total energy used over the life of one air conditioning or heat pump unit is converted to its global warming equivalent (indirect emissions), then the global warming equivalent of the direct refrigerant emissions is also added to this.

This method gives a much more accurate evaluation of the true global warming impact of a unit throughout its life cycle. Only looking to the GWP value is, therefore, not the correct way to assess refrigerant options as a unit with a “medium” GWP may have a lower total impact than a unit using a “low” GWP refrigerant.

2. SafetySafety is paramount when choosing and installing refrigerants. It is important to understand that many factors aff ect safety, including product type, volume of refrigerant

charge, room size, fl ammability and unit location.

3. Natural resourcesIt is as important to be effi cient with natural resources as it is to be energy effi cient and the environmental and economic parameters to “do more with fewer materials” should be adhered to. As such, refrigerant options must also be assessed on their potential for reuse. This same rule applies to the assessment of raw materials used to manufacture equipment. So, even when low effi ciency refrigerant options could be improved by using more refrigerant in larger systems, this would be detrimental to the total “ecodesign” balance.

4. Aff ordabilityAs it is predicted that 75% of future HFC emissions will originate from developing countries, it is important to fi nd solutions that are aff ordable on a global scale.

5. Energy effi ciencyEnergy effi ciency is obviously a key factor in refrigerant choice. Energy

effi ciency should be judged not only on the “seasonal effi ciency” averaged over the cooling or heating season, but also the effi ciency in peak load conditions (on very hot or very cold days). The fi rst of these is important in order to reach the energy effi ciency goals set by various EU directives (Ecodesign, Energy effi ciency directive, EPBD, Renewable Energy Source Directive) whereas the peak load effi ciency is important to avoid the requirement for extra power plants.

Next-generation refrigerant gases – the optionsWhich gas will be adopted by the HVAC-R industry as the next-generation refrigerant has been debated for some time. The likely candidates are R32 (which makes up 50% of R410A), HFO blends, CO

2 and hydrocarbons such as Propane and Butane. All have their own advantages and disadvantages and in reality, diff erent refrigerants (and combinations of refrigerants) will be used at diff erent times.

Comparing these alternatives to the common HFCs being used today

is a good place to start because the system design and installation costs, as well as energy effi ciency and safety, are understood.• HFO blends have very low GWP

and use compressors similar to those used in R134A systems, with comparable energy effi ciency. They are mildly fl ammable and system costs are, to date, unknown.

• CO2 has a GWP of 1 and is benign

and has very low cost. However, system costs are high as they need to operate at high pressure and effi ciencies are lower than HFCs, at 2.5 for a standard system. Used in retail refrigeration, users have reported issues with CO

2 being lost from systems when they are switched off .

• Hydrocarbons such as R290 (Propane), R600 (Butane) have low GWPs and are perfect for certain applications, particularly in sealed systems. While compressor design and cost and energy effi ciency are comparable to HFCs, they are highly fl ammable, which also means system costs are much higher.

• R32 has a lower GWP than R410A (675 compared with 2,044); off ers slightly better energy effi ciency; uses similar technology, keeping costs similar and is relatively inexpensive

to produce. It is non-toxic but is mildly fl ammable, requiring diff erent handling procedures.

R32 in briefR32 is already used in HVAC equipment, as it makes up 50% of R410A. It has a global warming potential (GWP) of 675, which is one third that of R410A (2,044). It’s more energy effi cient, resulting in a lower refrigerant charge and the potential to manufacture smaller units. As a single component refrigerant, it is also easier to reuse and recycle. Like many low GWP refrigerants, R32 is mildly fl ammable as designated in ISO 5149, requiring some new tools and procedures during installation.

The case for R32• R32 has a GWP of 675 compared

with R410A’s GWP of 2,044• R32 is more energy effi cient

than R410A (6% higher in a 4kW system)

• Less R32 is needed to achieve similar effi ciencies with R22. For example, an R22 system requiring a 1.2kg charge would only need a charge of 0.7kg if it used R32; a 4kW system using R410A needs 20% more refrigerant

• Smaller charges means heat exchangers and other components can be smaller, making equipment more compact (18% smaller when compared with a 4kW system using R410A)

• Like most low GWP HFCs, R32 is rated as A2L, which means there is low risk of accidents due to toxicity (A), and it is mildly fl ammable (2L) ie it requires more than 100g/m3 to burn

• (typically 300g) and has a burning velocity of less than 10cm/s

• R32 is a single component refrigerant, which means it can be easily reused and recycled; R410A is a blended refrigerant

• R32 has similar properties to HFO blends, in terms of fl ammability

• The boiling temperature of R32 is similar to R410A and slightly higher than R22

• R32 operating pressures are very similar to R410A

• R32 and R410A systems use the same types of refrigerant oil.

The burning issueBoth R410A and R22 are rated as A1, which means they are neither toxic nor fl ammable. However like most low GWP HFCs, R32 is rated as A2L, which means there is low risk of accidents due to toxicity (A), and it is Refrigerant comparison

mildly fl ammable (2L) i.e. it requires more than 100g/m3 to burn (typically 300g) and has a burning velocity of less than 10cm/s.

Tests carried out by Daikin and Suwa ,Tokyo University of Science show that even if combustion of R32 occurs (at concentrations of more than 320g/m3), it is not explosive and the possibility of fi re spreading is extremely low.

In fact, with residential air conditioners, even if the entire R32 charge were to leak within a room, its concentration would be so low that there would be no possibility of combustion. Furthermore, ignition does not usually occur from the type of electrical capacity used in domestic switches. And when performing soldering work during maintenance activity, a fl ame will blow out naturally and not continue to burn because the fl ow of leaking refrigerant is faster than the speed that transmits combustion.

R32 installation and trainingRegardless of the refrigerant gas being used, it is imperative that equipment is installed and charged by competent and well trained people. This means installers should be F-gas certifi ed and trained on the systems they are installing and the refrigerant gases being used.

As R32 is already part of R410A, the changes to installation procedures are relatively minor. In essence, installation is the same, the pipework is the same (using fl ared connections) and pressure testing and leak testing are the same. Of course, diff erent tooling will be needed – which is now available –such as gauges, manifolds, leak detectors and fl ame proof recovery systems.

The key issue is that installers will now be handling a mildly fl ammable gas, which means a new set of

charging and recovery procedures need to be followed - but nothing that will present a major challenge. For example, an R32 system must be ventilated during charging and recovery, to prevent a build-up of refrigerant, which could then be ignited by a naked fl ame. Ordinarily, this is not an issue but if an outdoor unit is being installed inside a building, then a fl ame-proof fan should be used to ventilate the area. Note that this is already a requirement for installing systems with R410A, as the R32 and R410A gases could separate and, as a result, could be fl ammable.

Looking ahead to 2015 and beyondThe phase-down of HFCs will lead to signifi cant change in the HVAC-R industry over the next 15 years. Installers, designers and end-users will have to adapt to using the next generation of refrigerant gases to reduce the environmental impact of air conditioning, heat pumps and refrigeration and to meet increasingly stringent legislation.

Installers need to ensure they are F-gas accredited, are fully aware of the new regulations coming in 2015 and are trained in handling R32 and installing any new systems. They should also keep up-to-date with the latest guidance from industry bodies such as REFCOM, ACRIB, IOR, F-Gas and DEFRA.

Daikin is also introducing installer training programmes covering the properties of the refrigerant and oils, cylinders, service and installation tools, as well as handling procedures, equipment installation and service.

The introduction of R32 will present a few challenges for industry, but Daikin is working hard to help ensure installers are ready, providing clear information on the new refrigerant and off ering training in its safe

48-49 Climalife Dehon.indd 48 19/02/2015 14:30

49COMPANY PROFILE

THE HISTORY OF DEHONThe very fi rst company in Europe to specialise in the distribution of chemical products was established in 1874 by Joseph Peintre in Belgium. The company, “Établissements Joseph Peintre”, went on to become the fi rst to import a new gas into Europe in 1935 called Dichlorodifuouromethant (R-12) under the new leadership of Mr O Dehon. His three sons have continued his work and the family business remains prosperous well into its 141st year.

In 1941 Établissement Joseph Peintre set up operations in France too, and after the second World War the concept of controlled temperature became fundamental and part of the development of the refrigeration industry. The commercial, industrial and domestic refrigeration market literally took off and saw the introduction of deep-freezing, freeze-drying, air conditioning and climatic engineering with new molecules being developed to support the broadening of applications.

In 1952, the group’s fi rst refrigerant packaging station was built in France and a second in 1959. This was necessary to support major users such as the Navy. The creation of depots located in strategic towns enabled Dehon to off er a 24-hour service.

The change from CFCs to HCFCs could have had considerable economic impact for the group. However, with a strategy of continual innovation and development, the Dehon Group created new products, such as heat transfer fl uids and also expanded its export subsidiaries in 1990.

CLIMALIFE – BEGINNINGSIn 2006, the Dehon Group created the Climalife brand, centralising its refrigeration, air conditioning and heating activities, and off ering its products and services worldwide using a vast international distribution network. Today, the organisation employs over 600 staff worldwide with revenues in excess of €185 million.

In 2012, IDS Refrigeration in the UK also adopted the brand of Climalife. Its 15 strong team; working closely with its European colleagues, support businesses throughout the UK with their technical expertise, product knowledge and tailored solutions across the fi elds of air conditioning, refrigeration, water treatment and renewable energy. Climalife UK continues to benefi t from being part of this worldwide leader in chemical expertise and distribution.

F-GAS SOLUTIONSOur industry continues to be confronted by new developments,

such as the end of HCFCs and the introduction of new F-Gas regulations. In response to this Climalife has gathered the experience gained across 140 years and three generations, to create a smartphone application called ‘F-Gas Solutions’.

The app, which is available on iPhone and Android smartphones, is a really useful tool that helps air-conditioning, refrigeration and renewable energy professionals to choose the right refrigerants that conform to latest F-Gas regulations.

Allan Harper, Managing Director for Climalife in the UK, says “The F-Gas Solutions tool is something new and innovative for the industry, helping to simplify the new F-Gas regulations for users. We hope that our customers, partners and prospective contacts fi nd it useful and if so, recommend it to others too. This is a free tool and the more users that can benefi t from it, the better”.

More information on the Climalife F-Gas App can be found on the Climalife website or can be downloaded from the Apple App Store and Google Play.

www.climalife.dehon.com

The Dehon Group – a worldwide player in performance chemistry - celebrated its 140 years’ experience in the distribution of refrigerants at the 2014 Chillventa exhibition. Climalife (IDS Refrigeration) in the UK is extremely proud of this history and will continue to share the Group’s experience and expertise with their customers and partners through 2015 and beyond.

In the seventh of our Women in ACR Series, we meet Carla Martins Nunes Laboratory Services Supervisor at A-Gas.

techniques – establishing the composition of mixtures, through separation – whether they are liquid or gas. With the economy in Portugal on the decline, I was looking for something more challenging and decided to look for work in the UK. Within a few weeks I was off ered a job by A-Gas and so I decided to move to the UK.

Tell us about where you workI joined A-Gas in December 2012. I began work as a quality control analyst in refrigerants, recycling and separating products. In 2013 I became laboratory services supervisor. I am in charge of a team of three and manage all the processes that take place in the laboratory. I work with all kinds of refrigerants.

Why is testing and analysing important in the manufacture and sale of refrigerants? It means that we can guarantee that our products are within the correct specifi cation and that they are of the highest quality. We continually analyse all the refrigerants and speciality gases that we sell or recycle to ensure our customers have the best available on the market.

Tell us about your backgroundI was born in Lisbon, Portugal. I am a graduate of the New University in Lisbon where I studied chemical engineering. I used to work in an environmental laboratory analysing pollutants and I was employed there for fi ve years. I specialise in identifying the composition of samples, using chromatography

WOMEN IN ACR

We troubleshoot on behalf of customers. So if they have a problem with their refrigeration system we can fi nd out on their behalf what the cause is. They can send us a sample of the refrigerant from a system and we check to see if it is high in moisture, if has above the expected levels of oil, if there is a possibility of corrosion within the system or if the gas is acidic. We can then recommend the right course of action to deal with the problem.

Last year A-Gas introduced a new carbon dioxide (R744/CO

2) analysis and testing service to improve the monitoring of CO

2 refrigeration system performance. Ensuring moisture content and other impurities are kept within the recommended levels should be a key focus for everyone working with CO

2 systems, as it can cause major problems. Overall, ensuring refrigeration systems operate within the strict boundaries of their specifi cation improves effi ciency, reduces maintenance costs and saves money.

What do you like about the job?It is very challenging. It’s always changing, especially with the new F-Gas legislation. It means that a best-selling refrigerant this year may not be so the following year and this forces us to rethink techniques and develop new methods of testing. The increase in the use of lower global warming potential (GWP) refrigerants

will lead to great changes in our industry and have a huge infl uence on what I do. It is very interesting job and you do learn a lot.

What is your advice to women thinking of taking up a career in the refrigeration industry?I would say go for it. It is a demanding but interesting career. It can be hard work physically but it can be very rewarding. I was recently in a meeting of 11 people and I was the only female. So there is room for more women in the industry. I don’t know what might hold back women from entering the industry. I never really planned to work in refrigeration, for me it was an opportunity that came along. It is a historical fact that few women work in engineering but I can say I have never been treated diff erently as a women and have always been treated very fairly.

Is your family with you in the UK?Yes, I am a working mum living in Portishead, near Bristol. I am married to Sergio who is Brazilian and we have a three-year-old son Gustavo.

What is your next career move?I have been in this job for a year now and what I want to do is perform as successfully as I can in my current position. I still have much to learn and many projects to develop in this laboratory.

Hafsa KalsoomWill Hawkins, ACR Journal’s editor, met Hafsa Kalsoom when visiting Jane Gartshore and Stephen Benton of Cool Concerns in October last year. Hafsa is new to the air conditioning and refrigeration industry and she is still studying in Birmingham. Read her interview in the April issue.

CONTRACTORS CORNER52


We’ve been inviting readers to write in and challenge

our technical experts by asking for advice on a wide range of air conditioning and refrigeration issues faced by engineers on a daily basis. The response has been great and we hope many of you have found our column informative and helpful!

This month, we’ve chosen to look at the subject of R22 renewal and a specifi c question from Mr J Chapman who writes:

With R22 now phased out, I’m struggling to understand the best options to recommend to my clients?

Lewis Jones, Technical Support Engineer at TF Solutions says:

With R22 now phased out, more and more companies will be looking for the best solution possible to replace their ageing system.

So what are the options?I would certainly be inclined to go down the route of a complete rip out of all current kit and ancillary. This would ensure that the system would be installed to the exact requirements and effi ciencies with no question against the potential wear and tear of the existing pipes

and other install components. Using a distributor that can provide the complete package for all your install needs is defi nitely recommended as they will be able to provide you with the most cost eff ective way of supplying a project such as this.

While a complete rip out would be the best option, in an ideal world it is also important to note that each renewal project is diff erent and circumstances ranging from inaccessible pipework to overall budgets can mean that it is not feasible. In this situation R22 renewal technology is a great solution.

With R22 renewal technology what you are basically doing is replacing both the indoor and outdoor units – it’s simple and straightforward as long as you stick to the system guidelines.

For example, Panasonic’s R22 renewal technology is very easy and straightforward to use and the process is as follows: 1 A thorough inspection of pipework is

essential, making sure sizes and pipe lengths are correct and adequate

2 Find out if there have been any compressor burn outs on the system with a straight forward oil test

3 Do an acid test

4 Pipe work fl ush using OFN and Diversi-Flush. This is a great product which unlike other fl ushing agents doesn’t need to be fully removed from the system once the system is clean as the vac pump will remove it

5 Fit a Panasonic renewal kit (liquid line fi lter drier, sight glass and ball valve) which ensures the cleaning process is complete.

6 Change the maximum system running pressure on commissioning to 33 bar without losing any effi ciency

OUT AND ABOUT54 OUT AND ABOUT


Out and About with Will Hawkins

PACAIRI first met Nigel Palmer from PACAIR last September on a manufacturer’s site visit in France. They have an interesting business. I met the team at their Hemel Hempstead office in January to learn more about it.

Nigel started the bespoke heating and cooling design

solutions business 11 years ago. They work closely with Mitsubishi Electric, LG and Toshiba and cover ‘anywhere up to Newcastle’ in the UK.

His team has steadily grown the business gaining new clients mainly through word of mouth. In fact, the business grew by over 22% in turnover between 2013 and 2014, and is set to do equally well in 2015. Some of their business growth has come from opening their new offi ce in the North West.

MAKING FRIENDS AND INFLUENCING PEOPLEIn a competitive market, Nigel put the success of the business down to the time PACAIR has invested in developing relationships with their clients.

“We are not after lots of enquiries from new customers,” said Nigel. “Our business growth comes through our reputation. We are very confi dent with, and close to, a tight knit group of customers. New customers are important for us, but we are careful about who we work with and for.”

PACAIR knows the Mitsubishi Electric products well and enjoys a close relationship with the brand. They have worked with Toshiba products for a long time too. However, to continue to grow the business, the company needs to keep developing its off erings and solutions.

To do this, the team has been looking at diff erent suppliers. The ‘new kid on the block’ for PACAIR is working with LG. When talking with Nigel in France, it was clear that LG had made a positive impression on them.

“LG has really got their act together, recently,” stated Nigel. “They have sorted out their warranty support, which makes a massive diff erence to our customers. The LG support and effi ciency/fl exibility of the product is what fi nally made our minds up about partnering with them.”

Having a great range of products is one thing. How you support your customers with them is another. In addition, that is what PACAIR does exceptionally well. Nigel’s team spends time building trust with its consultant and installer customers. They do this through a number of initiatives.

KNOWLEDGE ECONOMYPossibly the most important aspect of PACAIR is its knowledge.

Pacair O� ce

Out & About.indd 54 20/02/2015 14:26

55OUT AND ABOUT


“Consultants can’t be expected to know the full details on all product brands and types of applications,” said Nigel. “This is where we can assist to close the loop of product knowledge and provide the client the best solution.”

“Contractors need more installing details when selecting equipment,” said Nigel. “We help with detailed support and act like a design house for them.”

The specialist knowledge from PACAIR builds trust because their customers know they can rely on them for support. Trust is not just about knowledge either. The company will not provide quotes to people who are not suitably qualifi ed.

For example, if someone asks for a quote for a project and the person or company is not ‘F Gas certifi ed’, PACAIR politely turns them down. This meticulous attention to detail builds confi dence in their customers; customers know that they are dealing with an honest, loyal supplier that works in partnership with them. As a result, their high standards helps to win projects.

POWER FROM THE PEOPLEOf course, PACAIR’s success comes from its people.

Richard Parvin is the company’s technical manager who was with

Toshiba for seventeen years before joining the business. As Nigel put it, “He really does ‘think outside of the box’ when it comes to technical challenges.”

Robin Clark is the sales director who has been in the industry for over 30 years with experience from working with Toshiba and HRP. Jonathan Davies and Paul Wood, work for Robin supporting customers.

The operations manager, Paul Cross, was formerly Mitsubishi Electric’s logistics manager, as well as a spell with AMP. Stuart Law runs, and part owns, the sales operation from the offi ce in the North West, which has been a fi rst Year success. Stuart is a “very technical salesman” and was a Mitsubishi Electric specifi cation VAR Channel before coming to PACAIR.

The company has invested in a new quotation system too, which is accessible for the sales team on their tablet PCs. This means they can provide quotes for their customers almost immediately on-site. This responsiveness helps their customers win business too.

The philosophy of hiring great people and creating a ‘team atmosphere’ runs throughout the business. Besides, it is more than just how he works with employees and customers.

Every year, the business takes employees, customers (who are usually competitors) and their families away to a number of events.

As Nigel said, “When we have a good year, we like to make sure everyone benefi ts from it.”

The ‘family days’ involve customers and their families going away for a day to, say, an amusement park.

“It’s good to see how our customers talk to each other on the Family Days, despite being competitors,” added Nigel.

MORE SPACE TO THINK“We decided it was time to turn up the level of professionalism in the company,” said Nigel. “The expanded offi ce space will help with demonstrating and testing solutions with customers. Also, we need more room for the team to keep providing the levels of service clients rightly expect from us.”

PACAIR has a ten-year plan, which, by the look of it, is built on rock-solid customer service and a team of high quality individuals. When I met Nigel and his team, they exuded confi dence tempered by a very personal approach to business. No wonder they are so successful. It is a great company to visit and no doubt work with.

57TRAINING


The Big Bang Fair - 11th-14th March 2015 NEC, Birmingham

COOL SCIENCE VISION & AIMSIntroduce, share & explain the ‘Cool Science’ that makes refrigeration possible to a wider audience; Broadening the appeal and awareness of our industry, its importance in modern life, and the interesting jobs available. • Improve awareness and

understanding through education in a fun and engaging way.

• Demonstrate a practical and important use for STEM skills and qualifications.

• Sparking interest to attract young people to explore a career in cooling.

• Inspiring innovation from different backgrounds through widening participation and outreach.

The 25m2 Cool Science stand promises a fantastic combination of fun and educational activities:

• 2 bespoke BicyCool’s are being tested by their inventor Dr Ed Hammond at ECH (preview below)

• Rowing machine powered refrigeration system

• Cool Science logo made formed from frozen pipework

• A thermal imaging camera linked to a video wall

• Interactive Cool Science quiz on a wall of iPads

• 4 staff from ‘Mad Science’ with handheld dry ice experiments

• WorldSkills Ice Block demo rig

HOW MANY MILES DO YOU HAVE TO CYCLE TO COOL YOUR DRINKS DOWN?

ECH Engineering might have the answer.

Ed Hammond, principal at the Bristol-based refrigeration research and testing business, has built a ‘Refrigeration Cycle’ system which demonstrates the point.

Using an old bicycle, Ed has connected it to a compressor which, in turn, refrigerates a ‘cool box’ through human power generated by the cyclist.

Why?Ed is developing the system to

use on the Cool Science stand at this month’s Big Bang Fair at the NEC. The final system will consist of two new bicycles attached to the refrigeration system and it should be the main attraction.

New Lossnay RVX signifi cantly reduces ventilation power consumption

Mitsubishi Electric has announced the launch of the Lossnay RVX mechanical ventilation heat recovery (MVHR) series to deliver energy e� cient fresh, clean air with signifi cantly reduced power consumption.

Models in the range utilise a more e� cient DC fan motor which enables the Lossnay RVX to benefi t from signifi cantly lower specifi c fan powers (SFP’s). With SFP’s ranging from as low as 0.30 W/(l/s) up to a maximum of 1.61 W/(l/s) across the entire range, the Lossnay RVX units help comply with Building Regulations and legislation and allow for more energy saving and reduced carbon emissions.

The new units also benefi t from a wider air volume range with four distinct and selectable fan speeds compared to the three fan speeds with the previous model. Each fan speed is 25%, 50%, 75% and 100% of the rated air volume of each unit allowing more precise air volume control.

Blygold’s millionth protected heat exchanger!

Since its foundation in 1976, Blygold has treated hundreds of thousands of heat exchanger coil blocks

- and this year it reached the milestone of one million! Blygold was one of the fi rst manufacturers of coil protection

coatings. The applied thin layer, the high UV and chemical resistance properties and the patented application method are particular features of their products.

At Chillventa a trophy presentation was made to Blygold Italia and Euroklimat, the Italian-based company who had made the millionth coated coil. The millionth coil was an excellent example of European integration - the project involving the supply of two condensing units built by Euroklimat for their client, Heronhill, for the Sellafi eld Power Station in Cumbria.

As Nigel Manning, the MD of HeronHill, had been unable to stay for the presentation at Chillventa, it was decided that Charlie Wijveen (GM Blygold International) and Brendan O’Reilly (Blygold UK Ltd) would present the Heronhill award at their offi ce in Somerset, and give a warm thanks to all of the staff , who do such a sterling job.

NVQ SUCCESSES FOR AMP FOLLOWING TRAINING DRIVEStaff at AMP Air, the expanding Toshiba air conditioning distributor, have successfully completed advanced NVQs in Management and Customer Services as part of a training initiative.

Six senior staff completed the NVQ Level 3 course in Management following a nine month course of external study and on-the-job training, and a further six employees gained an NVQ Level 2 in Customer Services.

“We are delighted and very proud of their success in these national qualifi cations,” said Polly McConachie, AMP director. “Attendance on the courses was entirely voluntary, as they required a signifi cant amount of study outside work. It says a lot about those who took part – and the spirit of AMP staff in general, that they embraced the opportunity and made such a success of it.”

Those completing the NVQ Customer Services qualifi cation celebrated receiving their certifi cates with a visit to London’s Ice Bar. In sub-zero temperatures, and dressed in thermal capes, the AMP employees’ success was toasted with cocktails served in solid ice goblets.

The Bradford-based manufacturer, which supplies energy effi cient air management solutions to a global consumer base, supplied 15 air handling units, each of which had to comply with stringent HTM03 hospital specifi cations. They were installed to serve the main offi ce and pathology laboratories.

The team at Mansfi eld Pollard worked closely with WBS on the design of the system and developed a joint plan that took the project from the design stage through to installation and commissioning.

Pump House hire the mob at Chicago ASHRAE 2015

Well everyone said it would be cold, how wrong they were! The Chicago ASHRAE gave Pump House the warmest of welcomes; in fact the stand was so busy that the Blues Brothers were called in at one point to maintain order! It was like Black Friday all over again at their small and humble British Stand.

With the American market now moving towards a ductless system, or a split AC system in our words, Pump House were hopeful their products range would compete and provide solutions.

June Richardson at Pump House has reported that the feedback received from the show was outstanding. As a result of the show Pump House are now in negotiations with two confi rmed US Master Distributors.
