Optimisation is everythingA refrigeration or air conditioning contractor’s job may seem a world away from a website editor’s role. But, there are some surprising similarities.

Installing a refrigeration or air conditioning unit is the end result of long series of events, including understanding the problem in the first place, finding the right solution, making sure the solution is set up correctly and does what it is supposed to do. That’s the same when setting up a new website. The basics must be there to help make the website a success so that search engines understand what your site is about before delivering relevant visitors to it.

Thereafter, a website has to be ‘fed’ with really good information and optimised to make sure that you get what you want out of it. But, the real cost of a website is not the initial cost. It is the cost of keeping it going. You have to ‘tweak’ or optimise it all the time to squeeze every last drop of results from it.

That is the same with refrigeration or air conditioning solutions. The initial capital costs can be a fraction of the operational costs of running the unit over its lifetime. Getting the right solution in the first place is vital. But, if you don’t optimise it over its lifetime, you are going to pay a lot more for it than you think.

Rod Pettigrew Resigns as B&ES CEOThe Building & Engineering Services Association (B&ES) has announced that their Chief Executive, Rod Pettigrew, has resigned ‘with immediate eff ect’.

The split appears amicable and Andy Sneyd, President of the B&ES, was quick to thank Pettigrew for his 25 years of contribution to the Association.

Andy Sneyd stated,“My fellow offi cers, members of Council and the staff of the

Association all join me in wishing Rod the very best of good fortune in pursuing his future career.”

Andy Sneyd also stated that the Association has already put ‘interim’ plans into place to ensure continuity at the organisation until a successor is appointed.

The new CEO will be tasked with setting up a ‘strategic and operational board’.

Sneyd explained,”At the top of the new board’s agenda will be key issues

surrounding membership and marketing, the development of the Association’s own skills base and the future of vocational education and training across building engineering services.”

Rod Pettigrew joined the B&ES in 1991 as its commercial and legal adviser. In 1994, he became the head of the Commercial and Legal department. He was deputy CEO in 2008, becoming CEO in 2013. Rod served in numerous organisations including the CBI and as general secretary of GCP Europe for the UK.

UTC Finalises Acquisition of CIATUTC Building & Industrial Systems has completed its purchase of French heating, ventilating and air-conditioning company CIAT.

UTC Building & Industrial Systems – like its sister company Carrier – is a unit of United Technologies Corporation, American multinational provider to the aerospace and building systems industries.

“This strategic acquisition creates new opportunities in the European HVAC segment by enhancing the breadth of our portfolio and reach of our business,” said Didier Da Costa, President, HVAC Europe, UTC Building & Industrial Systems. “The addition of CIAT’s talented workforce, technology assets and legacy of innovation strengthens our ability to serve our customers.”

“The acquisition has provided an exceptional opportunity for us to continue to serve our customers while developing the CIAT brand in a complex European sector,” said Francis Guaitoli, CEO, CIAT. “This move allows us to fully leverage our technological expertise and the capabilities of our employees.”

UTC Building & Industrial Systems fi rst announced its intention to acquire CIAT in July 2014. With sales in more than 20 countries in Europe, CIAT now becomes part of the UTC Building & Industrial Systems’ European HVAC division, which provides HVAC systems and services to customers across Europe.

Honeywell Begins HFO-1234ze ProductionRefrigerant manufacturing giant, Honeywell, has begun full-scale production of HFO-1234ze, the low-global-warming-potential (GWP) refrigerant, at its plant in Baton Rouge, Louisiana, USA (pictured). The refrigerant is marketed within Honeywell’s ‘Solstice®’ product range.

“Honeywell’s Baton Rouge production facility is ready to serve customers around the world with this innovative material, which has an ultra-low GWP of less than 1,” said Ken Gayer, Vice President and General Manager of Honeywell’s Fluorine Products business. “We are seeing increasing demand for our entire Solstice line of low GWP materials, and this new product has already been adopted by a range of customers globally.”

The announcement follows on from Honeywell’s update in September 2014 that it is increasing production of low GWP refrigerants ahead of 2020 by when it aims to decrease production of high-GWP hydrofl uorocarbons (HFCs) by half on a CO

2 equivalent basis.

Facts about HFO-1234ze:• non-ozone-depleting• non-fl ammable per ASTM E681 and ISO 10156:2010 testing• GWP of less than 1• non-volatile organic compound (VOC)

Air conditioning and refrigeration companies looking for an alternative to HFC-134a (GWP 1300) and HFC-152a often choose HFO-1234ze.

Precision Refrigeration Triples Production CapacityNorfolk-based commercial refrigeration manufacturer, Precision Refrigeration, is tripling its production capacity because of high sales demands. The company bought a building next door which will add 14,000 square feet of production and warehouse space. Precision Refrigeration supplies equipment to the food service industry and is seeing its sales grow strongly.

“Our sales, both in the UK and overseas, have rocketed over the last 12 months,” says managing director Nick Williams.

“We’ve been growing at around 40% year on year and have been running extra shifts to keep up with demand. It’s a great position to be in but, of course, it brings its own problems.

“The new building gives us the capacity to meet rising demand and the potential to increase production substantially.”

The growth in sales and in its production capacity will create 20 new jobs in the near future.www.precision-refrigeration.co.uk

German compressor manufacturer, Bitzer, is to open a new, international training centre in Rottenburg-Ergenzingen, Germany.

The 1,500 square metre training centre has been under construction since August 2014 and is due to be completed in October 2015. It will be big enough to host several practical and theory training courses at the same time.

The training centre, known as the Schaufl er Academy, will off er hands-on training on its ‘cutting edge’ compressors and components, as well as theoretical training on how the products operate. In addition, Bitzer will be showing off its latest products including the CSVH compact screw compressor and the ORBIT 6 scroll compressor in heating and cooling applications.

“We decided to build the Schaufl er Academy for many diff erent reasons,” says Rainer Große-Kracht, Chief Technology Offi cer at Bitzer.

“The complexity of Bitzer compressors and products is always increasing, for example due to the integrated frequency inverters, electronic components and new CO2 systems. Technically demanding solutions also require a well-trained service staff .”

“The Schaufl er Academy will be the central training location for customers and employees from all over the world. Here we’ll off er the training courses that keep the maintenance teams of our business partners up to date.”

Can you teach a new dog old tricks?Forgive the play on a well-known saying in the headline but it sums up one of the things I was thinking about at the end of 2014 when we saw the results of the ACR Trainee of the Year Awards at the Belfry.

We were absolutely delighted that Julie Pringle, one of our trainers, was recognised at these Awards in December, not only because she is such a worthy recipient of this praise, but also because she clearly demonstrates that the right attitude can take you almost anywhere.

Despite being a ‘few years’ over school leaving age, Julie has embraced change and as the award shows, has now turned herself into an exceptional teacher and trainer.

I myself entered our industry at the tender age of 17 and I spent a long time learning my trade ‘on the tools’ but I also never forgot the lessons about making sure that every approach to every job or query was done with the central idea of getting the best outcome for the customer.

Attitude and AptitudeI have always said that you can teach a person how to do a job, but you cannot teach them the right attitude. That is something that you either have or don’t have. What you can do though is demonstrate the value of a positive and correct approach to any situation, especially by example.

If you read anything in the press about the next generation of workers, you could be forgiven for thinking that this ‘attitude’ issue is a problem and that today’s youth are more self-centred, or only motivated by the idea of celebrity or fame.

At the same time, as an industry, we face the prospects of a serious shortfall in new blood joining the world of air conditioning and engineering.

When we launched a national apprenticeship scheme with our partners last year, we expected the majority of the apprentices to have come straight from school and in the main, this has been the case.

I am delighted that in addition to being exceptionally keen to learn the practicalities of how the industry and the technology works, so far without exception, all of the apprentices have demonstrated a positive attitude to learning and look like becoming exceptional engineers and a credit to the companies who took them on.

So who knows, maybe the new dogs already know the old tricks!

RETAIL REFRIGERATION

Many consumers in UK are changing their shopping

habits, due to sustained pressure on housekeeping budgets. Shoppers are keener to shop around for value, including visits to discounters. They are also prepared to make more frequent shopping trips, typically to convenience stores, with fewer items in their baskets. These factors have impacted the large, out of town supermarkets, and signifi cantly the big four retailers, who have experienced the slowest growth in sales for a decade.

Unsurprisingly, the trend has resulted in a notable slowdown in the rate at which retailers are developing new, large format supermarkets. In January 2015, leading commercial property specialist, CBRE, reported that only 2.8 million sq ft of land is currently being developed for new grocery stores, the lowest

A shift in consumers’ behaviour and the growth of the convenience retail sector present new implications for the refrigerated display of perishable merchandise. Adande Chairman Nigel Bell reports.fi gure since 2008. CBRE also noted that a total of 43.81 million sq ft of UK land, owned by retailers, which is proposed for grocery store development or has already received planning permission, was not under construction.

CONVENIENCE STORE GROWTHNotwithstanding the stall in the development of new supermarkets, the big four retailers have confi rmed their commitment to the convenience store sector, in part to meet changing consumer shopping patterns. Smaller format stores are also attractive to retailers as they may be delivered with lower

capital expenditure, have less impact on the trade of existing superstores and incur less planning permission issues.

The proliferation of convenience stores is however raising issues for retailers at a time when they are seeking to cut energy consumption, across their estates, to meet obligations under the Carbon Reduction Commitment Scheme. Convenience stores and forecourt outlets have a higher kWh/square foot ratio than supermarkets and larger stores, mainly due to the fact that a higher proportion of fl oor space is committed to the refrigerated display of chilled merchandise.

“The big four retailers have confi rmed their commitment to the convenience store sector in part to meet changing

consumer shopping patterns”

RETAIL REFRIGERATION

HARSH ENVIRONMENTSFOR RETAIL REFRIGERATIONConvenience stores, especially those which were not purpose built for grocery retailing, are also susceptible to other factors, which may infl uence the effi cient performance of refrigerated displays and their energy consumption. In smaller stores, the proximity of refrigerated displays to the entrance door means that draughts can compromise the often fragile air curtains of open front refrigerated display cabinets. This results in cold air spillage from the cabinet, causing increased energy consumption, cold aisle syndrome and even unstable display temperatures, which may compromise the shelf life of merchandise. Similarly, lower ceiling heights in smaller stores exacerbate the impact of HVAC systems on the air curtains of refrigerated displays. Even the eff ect of sunlight, shining through glass windows, may create a heating eff ect on refrigerated displays causing an increase in duty and greater energy consumption.

THE INCONVENIENCE OF GLASS DOORSWhilst some retailers and equipment manufacturers have employed glass doors on open front multi deck refrigerated display cases as a means of making energy savings and addressing the issues associated with convenience stores,

AircellAdande’s unique and patented Aircell airfl ow management system addresses refrigeration energy savings and the issues associated with convenience stores, without the need for glass doors. Aircell is designed for open-front refrigerated multi deck cabinets, to deliver energy savings, temperature stability and improved customer comfort levels. Refrigerated cabinets with Aircell technology are currently being trialled at a Tesco store for the display of sandwiches and soft drinks.

Originally featured in the June issue of ACR Today magazine, Adande’s Aircell was shortlisted in the Refrigeration Product of the Year category at the 2015 National ACR Awards – turn to page 22 to see how it fared.

it is becoming increasingly apparent that glass doors are not necessarily the perfect solution. Indeed, the Carbon Trust Refrigeration Road Map, produced with the Institute of Refrigeration, even questions the value of glass doors in high traffi c convenience stores: “The levels of energy saving claimed vary considerably and must be related to the level of use of the cabinet. Cabinets with doors undergoing higher usage have been shown to save little energy when compared to an open-fronted cabinet…”

SHOPPING BARRIERSThere is also evidence to suggest that glass doors act as a barrier to shopping and particularly impulse purchases, especially in narrow aisled convenience stores.

“It is becoming increasingly apparent that glass doors are not necessarily the perfect solution”

In today’s competitive grocery retailing environment, it is unlikely that retail merchandisers will sanction any development, which may compromise sales. In addition, there is the capital cost of fi tting glass doors, together with ongoing maintenance and cleaning costs, which bring into further doubt the viability of the glass door option.

Retailers’ demands for signifi cant energy savings will continue to place pressure on equipment manufacturers to develop display cases, which operate more effi ciently, even in harsh convenience retailing environments. Whilst the jury is out on the suitability of glass doors, there are certainly opportunities for alternative technologies.

My name is June Richardson and I have worked for

Pump House now for 8 years. An Engineer I am not, but please do not allow such a tiny detail to stop you reading this article−myfirsteverattempt.And I need your help!

Pump House has been manufacturing Dairy Cabinet Pumps for 10 years, during which time sales have continued to grow.

Other manufacturers have challenged for the top spot. But yet, Supermarket Engineers out there have spoken. The DCP-30A now holds the title as market leader. I thought it only fair to tell you all.

PUMPING DEFROST WATER ANDDEBRIS AWAYWhen gravity drainage is not an option (and, to be really honest, I am delighted it is often not), then the engineer has no choice but to pump away the defrost water and debris (fondly referred to as ‘elephant snot’ - your words of course, not mine).

At 76mm high this ‘slim-line giant’ can operate at a maximum flow of 700 lph to heights of up to 23 metres. The secret to its success is the ‘Little Giant’ pump inside: its guts and its heart.

The Little Giant pump has multiple inlets top

OUR FIRST WORKSHOP TAKES PLACE AT THE NOTTINGHAM OFFICE

HIGHLY COMMENDEDJAVAC UK has been a market leader for several years in hand held refrigeration leak detectors and refrigerant recovery. The TEK-Mate and D-TEK units have become synonymous within the industry and JAVAC is one of the fi rst companies in the world to manufacture a refrigerant recovery unit back in 1989.

Javac noticed a need to introduce a new product into the market to complement their existing range and fulfi l a gap in the industry

for automatic system leak detection and pump down.

The i-Gas-4 recovery system is designed to recover most common refrigerants,

including R134a, R410a, R407 and R404. If a plant has a leak the iSENSE will detect the leak, a signal will be sent back to the i-Gas-4 or via the BMS (Building Management

System) to initiate a system recovery

pump down. This signal also allows possible shut down of the ACR system or shut down via low pressure trip and the refrigerant recovery to start.

WINNERThe AxiTop diff user has been developed to fi t the ebm-papst range of HyBlade axial fans as supplied to all the major refrigeration plant manufacturers.

The AxiTop diff user is designed to decelerate the fl ow, allowing a large proportion of the dynamic kinetic energy to be converted into static pressure.

The use of the AxiTop diff user also means greater variance for the user and for the development engineer. The AxiTop

diff user confi guration can be optimised for diff erent characteristics, depending on the application concerned. Either a greater air performance is possible with unchanged energy input, or unchanged air performance with lower energy consumption. The AxiTop diff user can also greatly improve acoustic characteristics. This is especially important in noise-sensitive applications (e.g. in cooling or air conditioning units operating at night).

The product also off ers the possibility to boost the air performance of fans on equipment that has been incorrectly sized for an application.

WINNERToshiba’s Total Refrigerant Leak Protection and Management System is an important leap forward for the industry.

In the event of a refrigerant leak, the unique Toshiba system now isolates the specifi c section of pipework containing the leak, enabling the rest of the system to continue functioning as normal.

It is designed for use in multi-tenanted buildings, such as hotels and offi ces.

If the sensor detects refrigerant in the

room, it triggers an alarm and an L30 fault code on the indoor unit, detected in turn by a central controller or BMS, and initiating the isolation sequence. The motorised valves close automatically, eff ectively isolating the conditioned space from the rest of the system.

Frigesco’s fl ash defrost system uses a phase-change material to capture waste heat produced by the refrigeration system in order to carry out highly effi cient defrosts.

It can save up to 20 per cent of the running costs of refrigerated display cases and cold rooms.

Traditional methods of defrosting refrigeration systems

require electric heaters, or “hot gas” from the system. Electric heaters add direct additional energy costs, while use of hot

gas makes the refrigeration plant less effi cient,

and therefore has an indirect energy penalty. The additional energy required for melting frost build-up can cost big end users millions of pounds

a year.

Frigesco’s system uses a phase-change material to store heat energy generated by the refrigeration system in the normal course of operation. It uses this heat to defrost evaporators, without the need for additional energy.

JUDGES’ COMMENTS:“This has great energy savings potential. A big tick for the technical design and installer benefi ts too.”

Designed and developed by Adande, Aircell is a unique and patented air fl ow management system for open front refrigerated multi-deck retail display cabinets. It has been designed to deliver signifi cant energy savings, improved stability of holding temperatures and customer friendly benefi ts. The technology is based on segmenting the merchandising envelope into small individual cells, with shorter air curtains, to reduce the spillage of cold

air from the cabinet. Aircell delivers the energy and environmental benefi ts associated with the fi tting of physical barriers, such as glass doors, without compromising the shopping experience. Because less cold air spills from the cabinet, chilly and often uncomfortable temperatures experienced by shoppers and store staff

are reduced. Crucially, Aircell does not require back panel fl ow to support the air curtain, so it does not over cool food at

the rear of the cabinet.

WINNER INDIVIDUALIan Wood co-founded Adande in 2005 and, for a decade, his mission has been the design, development and manufacture of refrigeration equipment, which not only saves energy, but also delivers sustainability in terms of equipment life cycle. He has also been driven by the need to extend the quality and storage life of perishable food to avoid wastage. This has been achieved, at the same

time as bringing to the market refrigeration equipment which off ers performance, operational and ergonomic benefi ts for the end user.

Ian Wood has repeatedly questioned conventional wisdom in the industry, claiming that the majority of modern foodservice equipment is of a similar design, sharing many characteristics with a domestic fridge from the 1940s. He has challenged his industry

peers with his claim that refrigeration needs innovation, not duplication.

His inherent engineering expertise and fl air for innovation have been matched by a commitment for sustainable product development, which has seen a strong growth in demand for Adande products and technologies across the world.

REFRIGERANTS


HCFC R22 refrigerant was phased-out under the

Ozone Depleting Substances Regulations EC 2037/2000 & 1005/2009, yet we are still receiving enquiries and orders for Daikin parts, including compressors, specifi cally for products designed to use the banned refrigerant HCFC R22.

For the European market, manufacture of equipment designed to contain HCFC R22 ceased between 2000 and 2003, so we are talking about equipment that is at least 12 years old and in most cases has exceeded typical life expectancy.

Given that from 1st January 2015 it became illegal to use HCFC R22 refrigerant for service and maintenance purposes, our concern is that purchasers of these spare parts are either unaware of the legislation or are using or considering so-called “drop-in” R22 alternative refrigerants.

Reliable, leak free, R22 equipment can be legally operated until it fails. However, in the event that it could “technically” be repaired,

Air conditioning suppliers face a new challenge since the ban on refrigerant R22 for service and maintenance purposes. Mike Nankivell, Marketing Director for Daikin distributor, Space Air, gives his view on the dilemma they now face.

Facing up to theR22 Challenge

once the existing R22 refrigerant charge is removed, it is illegal to re-charge/re-commission the system using R22. Should we, in such circumstances, simply stop selling parts for equipment designed to use HCFC R22?

Operators of such equipment basically have two choices:1. The system can be replaced

with modern day equivalent - recommended.

2. The system can be recharged with an alternative refrigerant -

NOT recommended.

Of course we are sympathetic to the potential cost burden imposed on customers as a result of the R22 phase out, however we believe the advantages in replacing the equipment, which has already exceeded normal service life, outweigh the disadvantages.

Retrofi tting and “drop-ins” The retrofi tting of any

refrigerant, other than that which the original equipment

was designed to use, is not recommended by Daikin, the manufacturer we have represented for over 34 years. Consequently no warranty is available on any component, including compressors, where an alternative refrigerant is used. Great care should be taken if considering any

alternative “drop-in” refrigerant for a number of reasons, including:₀ “Drop-ins” are usually anything

but – often involving costly preparation and modifi cation.

₀ Repairs may not be as cost-eff ective as new equipment in the fi nal analysis.

₀ The equipment will have other age related defects, which should be a consideration.

₀ This choice can only be considered a short-term measure.

₀ A variety of refrigerants are claimed to be suitable as R22 replacements, however their characteristics vary and may not work in your equipment or seriously impair its operation.

₀ Most R22 alternatives are HFC blends with relatively high GWP (Global Warming Potential). Given that older equipment is more prone to leakage, such refrigerants could prove to be an environmentally questionable choice.

₀ No warranty is available.

Our dilemma is whether or not we continue to supply parts for equipment designed to operate with HCFC R22. Our decision for the time being is to maintain supplies, for as long as they remain available, however, we will remind customers of the legislation and the pitfalls of temporary/interim solutions, and off er to quote for replacement Daikin equipment.

LOCATION, LOCATION, LOCATIONData centres located in technology hotspots such as central London have specifi c cooling constraints due to the high cost of space. Using available space for colocated customer equipment and business expansion, rather than plant rooms, is essential. The proximity of residential areas in central London means noise pollution becomes an issue, so large fans starting and stopping at night is unacceptable. Whilst cheaper locations are available, customers continue to demand colocation and data centre facilities in technology hotspots. Central London is arguably one of best-connected areas in Europe and a data centre in the heart of Tech City will always be an attractive proposition.One popular data centre cooling system is to combine Direct Expansion (DX) and cold aisle containment, with all air handling being above the raised fl oor.

In the 21 years since City Lifeline was founded to colocate telecoms equipment, cooling technologies have evolved a great deal and have moved far beyond the original CRAC units of 1993. As such, modern London data centres have needed to continuously redesign and regenerate their cooling systems to keep up with an ever-fluctuating industry. Bill Walsh,Operations Manager of central London data centre, City Lifeline, reports.

DATA CENTRE COOLING

Cold air is traversed across the top of the racks and falls into the cold aisle. It passes through the colocated customer equipment, then rises into DX evaporators, before it is chilled and recycled. However, as the technology world continues to evolve, are there more appropriate systems available?

AVOIDING THE COOLING PITFALLSMuch modern data centre cooling uses water as the heat carrier, but water needs a lot of space for plant and pipework. Adding storage tanks at roof level risks stresses the building was not designed to take, while water leaks on the upper fl oors are very risky in multi-story data centres. However, adding water storage at ground level uses valuable space, which could otherwise be used for colocated customer racks. It is sensible to limit water to a single vertical area, containing all the toilets and kitchen facilities, removed from the data halls and other equipment areas. A water leak in a data centre may then fl ood the toilets, but would have no eff ect on customers. Leakage control systems are available, using an air vacuum to suck leaking water back into the pipes, but are largely unproven, so operations managers often do not want to take the risk.

FREE AIR ANDEVAPORATIVE COOLINGFree air cooling and evaporative cooling, where air from outside the building passes over colocated customer equipment, are often considered by data centres. However, city pollutants give rise to long-term corrosion problems, particularly with modern lead-free soldered joints, while many colocation customers are uncomfortable with the idea of natural air, regardless of fi ltering levels. Even away from a city, the same precautions must be taken to prevent pollution in the event of a vehicle fi re in the vicinity of the data centre. Any data centre cooling system using external air sources should be indirect, with a heat exchanger between the data centre and the external air source, to minimize the risk of pollution damage to the customer’s colocated equipment.

Both free air and evaporative cooling use large volumes of air moving slowly which requires large ducts to channel the air. These take up valuable space within the data centre, are diffi cult to route around, restrict air circulation and are diffi cult to modify. In an industry where technology evolves year on year, the expectation is that everything will be changed at some

point. To transport heat, a volatile liquid in a 5mm pipe at 30 bar pressure is much more attractive than low pressure air in a 600mm square duct.

After carefully considering all the cooling system options, the City Lifeline data centre in London continues to operate overhead all-DX systems with cold aisle containment. These off er good effi ciency (with a COP of 3.5, the Partial PUE is 1.28), the smallest plant footprint, low roof loading, zero leak risk, off -the-shelf equipment, the best ease of modifi cation, the best growth staging, the least visual obtrusion and the least noise pollution. Cooling is a vital cog in the data centre machine and it is essential data centre architects and operations managers fi nd the solution which is most benefi cial, not just for their business, but for their colocation customers.

telecommunications equipment on the service provider’s premises.

David Marshall-George, UK Sales Manager at Condair, examines the use of humidification in modern data centre

s.



David Marshall-George

Data Centre Facebook

In modern data centres humidifi ers are required to prevent electrostatic discharge damaging servers and to off er high capacity, low cost evaporative cooling. ASHRAE recommends a data centre humidity level of 5.5°C dew point to 60%RH and an allowable range of between 20-80%RH. In most parts of the world, at some time in the year, humidifi cation is needed to meet these internal conditions.

Condair has been providing humidity control to data

centres since the computer era of punched cards and magnetic tape data storage. Humidity was needed to maintain the physical properties of the cards

and to prevent dust and debris adhering to the tape reels.

As technology has moved on, so too has the need for humidifi cation in the data centre environment.

Condair.indd 34 26/01/2015 14:52

35DATA CENTRE COOLING


“As technology has moved on so too has the need for humidifi cation

in the data centre environment”

A MICROSOFT SOLUTIONWhen Microsoft developed their $500 million mega data centre in Dublin, Condair provided them a humidifi cation solution that would help enhance their free air cooling strategy. For the majority of the year, the outside air alone is capable of maintaining the required internal temperatures. However, during the warmer summer months, the warm incoming fresh air can be fed through an evaporative humidifi cation system. This combined use of fresh air and evaporative cooling has enabled the data centre to practically eliminate the need for mechanical cooling.

The 35 Condair evaporative humidifi ers installed have the capacity to provide up to 10,930 litres of moisture per hour to the airstream feeding the 303,000 sq ft facility. The evaporating water produces an adiabatic cooling eff ect on the air, reducing its temperature by up to 8°C. The system was designed to reduce the incoming air from a maximum of 26°C in the summer to the room supply temperature of 18°C. At maximum output the humidifi ers could potentially provide 6,886kW of evaporative cooling across the whole facility while operating on just 17kW.

A FACEBOOK PROFILEAnother data centre giant enjoying the benefi ts of the Condair humidifi cation is Facebook. The company’s new data centre in Luleå, Sweden, employs both evaporative and spray technologies in its data halls to regulate humidity.

Peter Liddle, associate at Cundall, one of the consulting M&E engineers for the project, explains, “Facebook Luleå is employing a direct air cooling strategy within

their data halls, which uses the cold outside air to maintain the required internal temperature. Luleå’s cold dry climate means that humidifi cation is an essential component within the air conditioning process as without it the internal humidity could drop as low as 2%RH.

“This low level of humidity would be unhealthy for staff and present an increased risk to the servers from electro-static discharge.”

The cold water humidifi ers at Facebook can deliver up to 22,800 litres of moisture to the atmosphere every hour while consuming just 90kW of electrical energy. This high volume of humidifi cation is only viable with cold water systems, due to their low energy consumption. Mixing the return air from the data halls with the cold incoming air, increases its temperature suffi ciently to allow it absorb this huge volume of humidity and maintain the required internal air condition.

A far cry indeed from the days of punched cards and magnetic tape.

COLD WATER HUMIDIFICATIONIn the past, steam humidifi ers were the norm in data centres and were often integrated into the CRAC (Computer Room Air Conditioning) system. Whilst steam humidifi ers are still frequently used, cold water systems provide a more energy effi cient humidity control system, in addition to economic cooling ability.

There are two main types of cold water humidifi er - evaporative and spray. An evaporative humidifi er, such as the newly launched Condair ME, would be located inside a duct or air handling unit (AHU). As the air fl ows through its continually moistened evaporative matrix, it absorbs moisture and is humidifi ed. A spray system can humidify either within an AHU or directly into the data hall.

As well as humidifying, cold water humidifi ers will provide around 630W of adiabatic cooling per kilo of humidifi cation. With humidifi ers capable of supplying thousands of kilos per hour with very low energy consumption, their potential for economic cooling is great.

FREE COOLINGCold water humidifi ers are now often used with ‘free air cooling’ systems to either enhance the system’s cooling capacity, or provide high load, low cost humidifi cation to the large volume of air fl owing through the data centre’s ventilation system.

In a temperate European climate, the use of a free air cooling system can often meet a data centre’s cooling requirements, without the need for mechanical cooling, for up to 70% of the year. However, when used in conjunction with cold water humidifi cation this window of operation can be extended to 95% of the year, with mechanical cooling only required on the very hottest days.

Staying cool withhumidity control

The storage, exchange and management of digital information have become increasingly

critical to the majority of businesses. As a result, the environmental performance of the data centres used has taken on greater importance in their sustainability strategies.

Sustainable performance and environmental impact have also risen higher up the corporate agenda in parallel. Consequently making data centres ‘greener’ is now seen as a priority by many organisations.

The dominant environmental impact of data centres arises from their energy consumption, not just in terms of the electricity required to operate the computer equipment but also in maintaining the internal environmental conditions required for the equipment to function reliably. In particular, cooling and humidity control contribute a significant proportion of total energy consumption in a conventionally designed data centre.

As evidenced by a recent data centre project, the obvious way to address this challenge is to exploit technologies that enable effective temperature and humidity control with minimum energy consumption. In the case of this project, the solution proved to be a high-pressure adiabatic

humidification system that maintains the required humidity while also delivering evaporative cooling.

ENVIRONMENTAL CONTROLThe need to provide cooling to prevent computer equipment from overheating has been well documented. The need for effective humidity control is equally important but does not generally have the same profile.

Low humidity can cause electrostatic discharges that could seriously damage electronic components. The lowest limit recommended to avoid a significantly high risk of electrostatic discharge is40-45% RH.

In a data centre, however, the high temperatures created by the equipment can cause the relative humidity in the data hall to fall to

as low as 15-20% RH, so adding moisture to the air to prevent this is essential. Traditionally this would have been achieved by using steam humidifiers in air handling units but these units have high energy consumption and costly ongoing maintenance requirements.

LOW CARBON SOLUTIONWhen working with a data centre operated by a global manufacturer of printers and other IT equipment recently, we therefore proposed an alternative approach that would meet the client’s sustainability objectives and also reduce running costs.

The solution implemented makes use of a high-pressure atomising adiabatic humidification system that delivers water at high pressure through stainless steel nozzles to produce very fine, uniform fog droplets that quickly evaporate to humidify the air. A major benefit of this approach is that as the water evaporates it also creates a cooling effect. In this case, the cooling capacity of the system is approximately 690W per litre of water atomised, giving several degrees of ‘free cooling’.

As the Airtec adiabatic humidification is integrated with the ventilation system this arrangement also supports free cooling using outside air. It has been calculated that in a UK data centre free cooling using outside air can provide the required cooling for as much as 90%

In combining their cooling and humidity control systems with adiabatic humidification, data centres can significantly reduce energy consumption and carbon emissions. John Barker of Humidity Solutions explains.


Humidity solutions.indd 36 27/01/2015 17:26

of the year, with the remaining 10% being met by the supplementary adiabatic cooling. This arrangement can therefore eliminate the need for separate cooling plant, thereby reducing both capital and life-cycle costs.

THE SYSTEMAt the data centre referred to above there are four data halls, each of which has eight control panels and eight humidification racks to provide an output of 1200 litres of water per hour, per hall. Each of the distribution racks was custom-built and assembled on site due to their size.

Pump flow rate is controlled by a sophisticated system that includes an inverter to maintain the water pressure at 50 bar, ensuring that variable loads can be met whilst maintaining pressures that are sufficient to atomise the water. Independent stage control using a series of solenoid valves ensures that only those nozzles that are required at the time are activated.

The result is a very precise system with a wide modulation range that is able to respond efficiently to variable demand within each hall. The system provides very close control, to +/-2% RH, and has a specific power consumption of around 3.5W per litre.

Ease of maintenance is supported by using a design of stainless steel atomising rack that facilitates draining and automatic flushing of the lines. This helps to ensure that

DATA CENTRE COOLING 37


hygiene standards – which for a data centre are comparable to those for hospitals – are continuously maintained to the required level. Fully demineralised water is used to prevent dusting and further minimise maintenance requirements.

The success of this project clearly illustrates the benefits of considering environmental control in data centres as a whole, rather than dealing with the building services systems independently of each other. It also demonstrates the potential for making wider use of adiabatic humidification in data centres to the benefit of the environment and the organisation’s bottom line.

CONTINUING PROFESSIONAL DEVELOPMENT38

In this article, Keith Nicholls, Training Manager of British cooling systems manufacturer Airedale International, provides an introduction to the application of aisle containment in data centres. The topic is available as a CIBSE accredited CPD module from Airedale.

PRINCIPLES OF HEAT EXCHANGEAccording to the second law of thermodynamics, spontaneous natural processes will increase entropy until equilibrium is reached through the transfer of heat energy from a higher temperature area to a lower temperature area. Maintaining traditional room design conditions requires a high energy input; however, higher design temperatures, within ASHRAE guidelines, will signifi cantly increase opportunities for energy saving free cooling and potentially create additional rack space.

INTRODUCTIONIn this short CPD article we will show how aisle containment can be applied to meet the key objectives in e� ective data centre design:1. Improving uptime by reducing the dependency on mechanical

cooling2. Increasing energy e� ciency and lowering PUE3. Controlling capital costs through high density solutions 4. Cutting operational costs primarily through energy savings5. Reducing footprint and increasing cabinet density

Better by design: Exploring containment options to optimise every cooling kW

TYPES OF AISLE CONTAINMENTTraditional open aisle data centres use perimeter PAC (precision air conditioning) or CRAC (computer room air conditioning) units to channel cold air up through a raised fl oor void via grilles positioned in front of the IT cabinets. This has signifi cant disadvantages as there is no separation between the supply and return air and signifi cant air movement within the room resulting in poor return air control.

COLD AISLEIn cold aisle confi gurations the supply air is contained and the hot discharge air allowed to return to the CRAC unit. Because the supply and return air are kept separate, the room temperature can be slightly higher than in open aisle architecture.

HOT AISLEWith hot aisle architecture, the supply air is directed onto the front of the racks and the hot discharge air

ducted back to the PAC units through the ceiling void; this provides better room temperature control and allows for higher return air temperatures, increasing free cooling opportunities.

Even greater effi ciencies can be achieved by using in-row hot aisle containment such as the InRak™. This confi guration reduces airfl ow with a controlled cooling path and, because airfl ow is predominately horizontal, does not require fl oor and ceiling voids. All of the energy is applied to cooling the racks, not the room.

Rear-door compact hot aisle coolers such as the OnRak™ which are fi tted directly to the discharge of the cabinet similarly shorten the air path and air movement.

The application of aisle containment provides much closer management of the supply and return air paths within ASHRAE guidelines which calls for supply temperatures below 27°C. By eff ectively managing air fl ow, higher air temperatures can be returned to the cooling coil to drive heat exchange and maximise free cooling opportunities.

Let’s see this in practice based on a typical 500kW facility:In an open aisle confi guration, supply and return air temperatures


Airedale.indd 38 27/01/2015 18:08

“The highest e� ciencies are however achieved using a compact hot aisle confi guration”

will typically be set at 12°C and 24°C respectively. Because air mixing occurs, the room has to be kept at an artifi cially low temperature.

By introducing cold aisle architecture where the hot and cold air are separated, the supply air temperature can be increased to 17°C and the return air temperature to 27°C. The room temperature is governed by the return air temperature back to the PAC units.

With both of the above confi gurations rack load is 5kW, meaning that 100 cabinets will be required to satisfy the 500kW load.

Real benefi ts start to be achieved when hot aisle architecture is introduced. Supply and return air temperatures can be increased to 22°C and 35°C and, with no air mixing within the room, rack load can be increased to 10kW, requiring only 50 cabinets to satisfy the 500kW load. This creates the opportunity for an additional 420kW of IT load within the space. Room temperature is governed by the supply air temperature leaving the PAC unit. With higher cooling output per footprint, the InRak™ in-row cooling system frees up further space within the data centre due to an increase in cooling load per square metre.

The highest effi ciencies are however achieved using a compact hot aisle confi guration. With rear-door OnRak™ cooling units, the air-on temperature to the cabinet is maintained at 27°C in line with ASHRAE guidelines; the heat exchange occurs at the rear of the cabinet and provides a high discharge temperature (in this case 42°C). This architecture halves the number of

cabinets required to meet the 500kW load to 25 with a high rack load of 20kW per rack. This creates an additional opportunity for 1880kW of IT load within the space

SUMMARYOpen aisle confi gurations provide limited opportunity for free cooling due to the lower return air temperatures required to keep the room artifi cially cool. Based on our typical 500kW installation, an open aisle data centre will operate in full free cooling mode for just 1% of the year, with a requirement for some form of mechanical cooling for 51% of the year. These fi gures reduce to 6% and 32% respectively when cold aisle containment is implemented.

Hot aisle containment will further increase free cooling opportunities with the InRak capable of delivering full free cooling for up to 25% of the year (18% of the year in

mechanical cooling mode) and the OnRak delivering free cooling for up to 20% pa and relying on mechanical cooling only for just 11% of the year, with a high percentage of concurrent free cooling that maximises the part-load effi ciencies of components.

Open aisle and cold aisle architectures require similar rack and cooling equipment space. The hot aisle and InRak systems require less overall fl oor space, which is improved still further with the OnRak system.

In addition to freeing footprint, aisle containment reduces lifecyle costs and lowers PUE (power usage eff ectiveness). PUE is the ratio between the total facility power1 divided by the IT equipment power. The lower the PUE the more effi cient the data centre.

Building owners demand a broader offering today, a broader set of services that goes beyond simply the equipment. They want building technologies, reliability, operating practices and intelligent building services that will create better, healthier, more comfortable and more productive indoor environments. Jeff Moe, vice president, product management and marketing for Trane reports.

Technological evolution is significant and, especially

in Europe, the role and impact that legislation has had in focusing on refrigeration and efficiency is increasing. The importance of sustainability – for both businesses and customers– grows significantly too. The result of which is significant innovation in product and service offering to support the sustainability and efficiency in this market.

Trane focuses on providing a complete portfolio of services,

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

from initial modelling and design of the system, through products, to service and maintenance. Rental offering aims at meeting each customer’s specific requirements for temporary cooling needs due to capacity expansion, contingency cooling, special events, emergencies, and seasonal needs.

Moreover, energy retrofitting of the existing European building stock could yield annual energy savings of nearly 50 percent and reduce CO2 emissions by more than 50 percent as well as create around 700,000 jobs, according to the Europe’s Buildings under the Microscope report, prepared by the Buildings Performance Institute of Europe1 .

HEATING AND COOLING IN MODERATE CLIMATESMany building owners and managers in moderate climates such as in northern Europe face the need to provide simultaneous heating and cooling in different spaces of their facilities to meet sustainability targets set such as the United Kingdom’s challenging building regulations.

Trane’s new range of multi-pipe new chillers simultaneously deliver hot and chilled water and up to full energy recovery resulting in significant energy efficiency improvements and reduced operational costs.

The range is particularly suitable

in countries with mild winters like the UK and perfectly fits in buildings where the heating system is designed for low temperature radiators or under floor heating operating with hot water temperatures of 35- 50 degrees Celsius.

The system provides both heating and cooling from one single unit, an obvious benefit for the customer. In place of a traditional chiller with an additional boiler, installing this simplified multi-pipe system results in lower investment costs, reduced use of floor space and lower total operating costs with only one unit to maintain instead of a separate chiller and boiler.

Annual energy consumption for multi-pipe systems is lower than in the case of comparable conventional systems. The use of renewable energy, when operating in heat pump mode, is one of the contributors.

OPTIMISING PERFORMANCEBuilding owners and managers want their facilities to be one of the best in terms of comfort, performance, efficiency and sustainability. They demand improved efficiency choices with the right level of return on investment. Today, more than

before, they also face acoustic challenges as urban areas are growing and expanding often to commercial and sometimes industrial areas creating the need for the heating, ventilation and air-conditioning (HVAC) systems to be as quiet as possible.

The HVAC industry is responding to these needs and, as part of an innovation drive, Trane introduced five new chilled water systems with capacity ranges from 20kW to 14,000kW, to add to the new range of multi-pipe chillers.

Expertise in commercial cooling systems has made it possible for Trane to develop a suite of tools, including proprietary software, designed to analyse and diagnose installations. Every chiller plant system is unique and the cooling system optimization program from Trane, instead of following a “one size fits all” approach, is designed to match chiller plant complexity

with the customer’s investment and requirement capabilities.

When these tools are combined with design and project management expertise, Trane is ideally positioned to develop and execute solutions to reduce lifecycle costs by improving system effi ciency. Building owners can improve energy effi ciency, lower overall utility costs and fi nd the best solution from a fi nance and performance target perspective that also complies with current regulations.

COMMITMENT TO THE CLIMATENew European legislation creates an opportunity to deliver new cost eff ective solutions to the market. The F-gas regulation together with eco-design standards impacting the HVAC sector incentivise innovators to bring products to the market that have a lower environmental impact combining energy effi ciency and lower global warming potential (GWP) refrigerants. In other words, new lower GWP refrigerants need to also be as energy effi cient, or even more effi cient, than the refrigerants they are replacing.

Last year, Ingersoll Rand made an environmental commitment to its employees, customers and shareholders – a roadmap to signifi cantly increase energy effi ciency and reduce climate impact from its operations and product portfolio by 2030 (with milestones at 2020).

The commitment includes reducing greenhouse gas (GHG) emissions related to its operations by approximately 35% by 2020; reducing GHG emissions related to its products by 50% by 2020; and investing $500 million in product-related research and development over the next fi ve years to fund the long-term reduction of GHG emissions. This commitment is

estimated to result in the avoidance of approximately 20,850,000 metric tons of CO2e globally by 2020. This is equivalent to the energy used by nearly 2 million homes for one year.New technologies and approaches provide tremendous value to organisations, especially considering that energy effi ciency of buildings lies in holistic solutions. While the process begins with “saving energy saves money,” it ends with much more: greater capital

fl exibility, improved organisational and occupant eff ectiveness, a cleaner environment, and a superior reputation for sustainability.

COMPANY PROFILE46

“In 2015, there are over 10 new product launches scheduled and it promises to be an exciting year for Viessmann

Refrigeration Systems.”


A family business founded in 1917, the

Viessmann Group is now a leading international

manufacturer of heating, cooling and climate control technology.

Jim Whelan, Director of International Business at Viessmann Refrigeration

Systems discusses the company’s recent history

and plans for 2015.

Headquartered from Telford, Veissmann Refrigeration

Systems now has a dedicated sales force which is focussed on delivering a comprehensive range of refrigerated merchandising display cases and cold rooms.

2014 was a year of change for Viessmann Refrigeration Systems; it was the first year that the cold room and refrigeration sections of the business became one. At the end of 2013 Viessmann Group acquired Norpe in Finland – leading Scandinavian manufacturer of innovative commercial refrigeration systems. Expanding and integrating

Iconic maximises product display area, almost doubling that of a traditional island freezer while maintaining the same size ‘footprint’. In addition to this, it also addresses the traditionally bland and cold atmosphere of in store freezer sections. Research has shown consumers on average only spend 20 seconds in the frozen food aisles. Through a combination of practical and aesthetic design choices Iconic seeks to change this. A pilot scheme has already seen Iconic increase frozen food sales revenue by 9.7 per cent and increase profit by 18.1 per cent.

It is a product that shows Viessmann’s dedication to offering smarter retailing options to customers based on our diligent research practices. The company

is constantly looking into ways of lowering life cycle costs, developing unique products and providing consumers with superior shopping experiences.

Challenges lie ahead for our customers in 2015 in light of the Council of the European Union approving a number of revisions to the F-gas regulations. They will need to assess and renew equipment and products, which for many will be a significant undertaking. Viessmann Refrigeration Systems will endeavour to embrace this latest round of revisions by continuing to develop innovative, practical solutions that meet the changing needs of our customers and their consumers.

www.viessmann.co.uk

the Norpe products, alongside the company’s established temperature-controlled cold room ranges has been a key step for the Viessmann Group to start building a leading position in the refrigeration business, similar to its position in the heating sector.

Norpe is involved in the design and manufacture of refrigeration cabinets, integral cabinets, power packs and evaporators. It has been a major part of the retail solutions industry for 60 years, producing remote and plug-in cabinets, and as such is a major asset to the Group.

With the addition of refrigeration cabinets, Viessmann’s portfolio becomes an enviable one. Bolstered by the display chiller products, it now covers both the back and front of house refrigeration requirements, helping the German, family-owned company toward its stated goal to become a full service provider of cooling technology.

In the UK market, all refrigeration products are now sold and branded as Viessmann. The ‘hot and cold’ divisions have also been physically united in the UK with the move of the refrigeration division to Viessmann’s UK headquarters in Telford last summer.

In 2015, there are over 10 new product launches scheduled and it promises to be an exciting year for Viessmann Refrigeration Systems.

ICONICAlready the company has introduced further new product innovations to market. At the Euroshop 2014 exhibition the Iconic semi-vertical freezer cabinet was an eye-catcher. Semi-vertical chillers have been commonplace for a while, but Iconic is the first freezer developed in this format.

Viessmann’s recently developed Iconic; the first semi-vertical freezer cabinet. It has been created to better suit the demands of use and maximise product display area.

CONDENSATE REMOVAL48


In today’s climate, grey water is becoming increasingly important. In the past removing condensate water from an air conditioning unit was a challenge and was often not viewed as being economically viable. However, Aspen Pumps has been providing water condensate recycling solutions for more than 20 years.The benefits are huge, as Serge Becker, Sales & Marketing Director at Aspen Pumps explains.

As water becomes an increasingly precious

resource, using it in a sustainable way that minimises waste has become critical. Grey Water is the most commonly used type of water in the world, and it is also the most wasted on a daily basis. It is defi ned as water that is created through wastewater in the home, excluding toilet water (or black water). We unknowingly generate up to 140 gallons of it every day when we have a shower or bath, or use the washing machine or dishwasher. It is a common misconception that grey water cannot be recycled, when in fact in can be used to wash clothes, water the garden, keep our cars cool or water a constructed wetland.

When thinking about recycling, what most people do not realise is that they have an additional source of grey water in their houses that can produce between 5-20 gallons of water per day.

GREY WATER FROM AIR CONDITIONING SYSTEMCommercial and domestic air conditioning is becoming more and more commonplace. Waste water or condensate water is generated as warm air is cooled by the air conditioning system and humidity in the air forms condensation. This condensate is then collected in the unit and traditionally is then pumped outside into a drain where other wastewater is sent, or drained straight out of the building using gravity. A standard air conditioning unit will produce on average 5475 gallons of grey water a year; that is enough to fi ll 110 bathtubs, wash a car 547 times, do 138 loads of washing, or could fl ush a toilet 2737 times per year!

CONDENSATE CHALLENGESIn the past removing condensate water from an air conditioning unit was a challenge and was often not viewed as being economically viable. However, as the search to discover innovative ways to recycle water gathers pace, and with more people looking to air conditioning systems to keep their homes cool, the theory of recycling the grey water generated from air conditioning units has become a reality. With the right drainage systems and correct pumping methods, it is entirely possible to have suffi cient recycled grey water to signifi cantly reduce water bills and help sustainability.

For instance, Aspen Pumps is a company which has been at the forefront of air conditioning grey water recycling innovation, and it has been providing water condensate removal solutions to the industry for over 20 years. Being able to reuse grey water is imperative to ensuring that Aspen, and other companies involved in this

area, work in a way that protects the environment. With water becoming scarcer in many regions across the globe it is critical that people are off ered the tools to reuse their grey water. Aspen off ers a range of pumps that will lift the water up and into storage tanks, outside water butts, and other water drainage systems, which means that the water can then be reused and recycled as appropriate.

GRAVITY DRAIN SYSTEMSTraditionally, gravity drain systems have been used to recycle water through drainage into storage tanks where it can then be recycled. However, gravity drain systems can only work if there is suffi cient space when installing an air conditioning unit, or attempting to drain the water into a water recycling unit. Draining the excess water into a bucket or straight out the window onto the exterior wall was common installation practice – as there was not a better way available.

Since then, the development of effi cient pumps in this market has allowed installers to fi t a pump either in, on or above the air conditioning unit allowing the water to be pumped up and away from the unit without the need for gravity. Ultimate fl exibility is guaranteed, as AC units can now be placed as desired by the home builder/owner, instead of placing the unit close to an outside wall which is a requirement for gravity drainage.

In buildings where space is an issue and water recycling is more diffi cult, air conditioning systems connected to a water recycling tank

with a pump means that an average tower block with 150 fl ats could recycle up to 22,500 gallons of water per month. Enough water to fi ll a 21ft swimming pool! With over 80 million air conditioning units being sold in America and 50 million in China annually, if every one of those people who bought a unit used a condensate water pump to save water, there would be a saving of over 700 trillion gallons of grey water per year.

For instance, the newest pumps, such as Aspen’s, have the ability to pump grey water up to a height of 20m, meaning that the water can be pumped into a roof top storage tank and reused for washing clothes, washing cars and watering gardens. This creates fantastic sustainability opportunities.

Whatever the country or environment, if there is an air conditioning unit, there is an opportunity to tap a valuable source of recyclable grey water. The average person uses 140 litres of water per day with only approximately 5-10 litres of this is used for drinking and cooking. With this in mind, with the right pump, trunking and accessories the average household will reap huge benefi ts from water sustainability opportunities and economic savings.

The revised F-Gas regulations from manufacturers, installers, managers and owners of commercial cooling and refrigeration technology to advance the

phase-down of fluorinated gases with a high global warming potential (GWP). This intermediate step in the EU’s quest to significantly lower the volume of F-Gas sales by 2020 is expected to drive the adoption of more climate-friendly technology.

Often used as a substitute for ozone-depleting substances like hydrochlorofluorocarbons (HCFC), fluorinated gases (HFC) may not damage the ozone layer, but their global warming effect remains up to 23,000 times higher than CO2. The new F-Gas regulations to phase down their use came into effect in January 2015. Daikin UK’s Legislation Specialist, Graham Wright summarises the challenges and opportunities that this latest legislative update presents to installers in the UK.

F-GAS 2015 IN A NUTSHELL

F-GAS UPDATE

THE PHASE DOWN The abolishment of HFC will take place in steps, the first banning the use of HFC refrigerant with a GWP over 2,500 in new refrigeration equipment by 2020. However, recycled and reclaimed HFC >2,500 GWP will still be permissible for servicing existing plants until 2030. The aim is to phase out refrigerants such as (R404A as their GWP is above the 2500 threshold) and phase down refrigerants such as R410A, 134a, R407C and R32 . These refrigerants will now have to be measured by CO2-equivalent emissions against 2014 levels, therefore making the use of lower GWP refrigerants such as R32 more attractive.

The revised regulation also reinforces the importance of preventing emissions through regular leak checks, improved installer training and qualification, as well as appropriate end of life treatment.

onsite staff and contractors are F-Gas trained and registered to undertake operation and maintenance tasks. Likely to be provided by manufacturers, such training will cover updates on regulations, standards, emission prevention, recovery, safe handling and alternative technologies. To reduce F-gas use and facilitate the transition to lower GWP HFC refrigerant over time, certified persons must also keep accurate logbooks about the type, origin and quantity of F-gas installed, its disposal as well as equipment decommissioning. This information has to be kept for a minimum of 5 years. Similarly, the end user will be required to provide evidence that the installation of non-hermetically sealed pre-charged equipment will be installed by a certified undertaking, or else the equipment may not be sold to them.

GETTING THE STRATEGY RIGHTAs environmental policies are evolving at a faster rate than ever and implementation plans on European and national levels are stringent, businesses across all sectors need to prepare the right strategies to continue an effective and compliant business operation. Experienced installers and manufacturers will be able to offer advice on how building owners and managers can best meet these new environmental and legal obligations.

www.daikin.co.uk

LEAK CHECKSMore specifically, leak checks are subject to new thresholds expressed in tonnes of CO2-equivalent quantities rather than kilograms, for example 5 TCO2-eq instead of 2.4 kg, in the case of R410A. In practice this means that the charge limit for leak checks will depend on the GWP of the refrigerant used. RAC systems will need to be installed and serviced by certified professionals, which will make specialised training all the more important in the future. However, verifying the certification of service engineers or installers is not only down to the equipment operator under the new law: it is within the responsibility of any person or company assigning a task to another person or company.

RECORD KEEPINGBuilding managers and installers alike, will need to ensure that relevant

WOMEN IN ACR52


Tell us about your Education

I went to an all girls’ convent school. When it came to Physics A’ level – there was no Physics teacher, so we had to be shipped to local boys’ school for Physics lessons. The Physics teacher there had been an engineer before he went into teaching, and it was he who suggested to all of us to consider Engineering as a career.

In the sixth of our Women in ACR series we feature Jane Gartshore. Jane is one

of the two directors who own and operate Cool Concerns Ltd, providing practical

consultancy and training for the refrigeration industry. She is immediate past president

of the UK Institute of Refrigeration and has worked in the industry for 38 years.

JANE GARTSHORE

How did you come to set up your own business?

A colleague from Prestcold and I had long talked about there being a market for practical training and consultancy. Then, when he was made redundant in 1991 - we decided to go for it. In eff ect, we stopped work one day and started the business the next. Because I’d been in Technical Sales, I had a lot of contacts, who generated a little bit of work to start with. As a woman, people will remember you, and as long as you do a good job, they’ll remember you in a positive way. So I feel that being a woman in this industry has really big advantages.

It didn’t feel a scary prospect - my original business partner Roger had redundancy money that he was willing to invest in the business, although it didn’t require much, as we both initially worked from home. Plus as my dad had run his own business, that’s the background I come from, so it felt natural to work for myself rather than being an employee.

Was there much competition from other training companies?

Mike Creamer was setting up a training company at the same time, although he’s more air conditioning and we’re more commercial refrigeration, so there is not that

How did you come to start working in the refrigeration industry?

One of the companies that off ered me graduate training was Prestcold, a British manufacturer of commercial refrigeration equipment based at Theale, near Reading. Prestcold was part of a very large group and off ered very good graduate training, involving spells at college learning practical skills and a refrigeration-related course. I was quite a rarity, not only as a woman but also as I was in fact the only graduate engineer that Prestcold ever took on.

I started off designing and developing new products and also backing up manufacture. The other part of my work was working in testing and development of new products. I did that from 1977-82, and then I moved into Technical Sales, which I absolutely loved. I found a particular niche in that role, perhaps because much of sales is about communication, which - generally speaking - women tend to be naturally better at than men. Plus it was a worldwide role: I had opportunities to go places and met many diff erent people.

Everything else I’ve learnt in the refrigeration industry, I’ve learnt on the job, particularly from a practical point of view and how the industry works.

WOMEN IN ACR

What areas of the business are you personally specifi cally involved in?

Steve and I could pretty well do everything, but it has worked out that way because I’m good at writing, I do a lot of the writing. Steve does a lot of the standards work, because Steve is good at retaining a lot of information.

Is there anything you know now about the industry which you wish you had known before?

I wish I’d had more opportunity to do hands-on practical stuff earlier on. I don’t see that physically there’s a barrier to women doing pretty well anything in the industry. Sometimes I ask men why they don’t employ more women. One who ran a reasonably large local contracting company replied saying: “I employ men, if I employ a woman to work alongside a male on a job, I know what’s going to happen…”

What really ignites your interest in the industry at the moment and your role in it?

Alternative refrigerants - because to me that’s what can make potentially the biggest diff erence. When I took on the Presidency of the Institute of Refrigeration my particular point of interest was to see what we could do to reduce leakage of refrigerant. Had we done that back in the 1960/70s, we wouldn’t have ended up having to phase out CFCs. It is an interesting topic from both environmental and cost perspectives.

How do you see your career and your business progressing from here?

Doing more of what we do well. there are so many things that we do really well that most people

don’t necessarily know we do well. So we need to work on marketing ourselves better.

We’ve recently taken on somebody to take care of the training side of the business. This frees us up to concentrate on what we want to concentrate on, which for me is how better to promote the business.

What are the challenges that this industry presents?

I’d say that for anybody coming into the industry they need to be encouraged to network and meet people, not be afraid to get involved. Steve and I have both benefi tted enormously from time we have spent doing voluntary work e.g. for the IOR and the BRA.

I can’t say I have ever felt it a major disadvantage being a woman in the industry. I would say to any woman working in business or in industry - don’t view yourself as being a woman - view yourself as being whatever it is your job role is. It is also important to understand that there are some things you can do better than men, and that equally there are some things you can’t do as well as men.

What are the benefi ts of your role?

Running your own business, you get out what you put in. Flexibility, independence, being in control of what you’re doing are all advantages. It is not about the pay as such, we are not driven by money. I’m in my late fi fties and with a bit of planning I’d like to think I’ll be able in the near future to take a couple of months out to go to New Zealand. I’ll fi nd work while I’m out there too, but the fl exibility is crucial in having the options to do that. Both Steve and I might take time out at diff erent times, but when you are running your own business, these things balance.

much crossover. Otherwise it was only colleges at the time who were providing training, and we were not looking to off er the sort of longer training courses provided by colleges, e.g. NVQs. We wanted to off er short, sharp training courses, one week maximum, so that’s what we did. Our fi rst major job at that time was consultancy rather than training - in energy effi ciency. It was at a time when as an industry and as a country we were just starting to realise energy effi ciency was a necessity. And we were very fortunate to be in the right place at the right time with hydrocarbons. Our understanding of the practical application of hydrocarbons has taken us all over the world.

What are Cool Concerns’ specialisms?

Commercial refrigeration is the sector we operate in. Our particular forte is that we provide practical hands-on training. We know the industry, we know the technology. We provide training by engineers for engineers, and that is part of what we do really well. When service engineers come on our courses we talk the same language as them, we understand the problems they’re up against in everyday reality.

On the consultancy side - because of our backgrounds we have a wide knowledge-base – and so we are able to off er a very wide range of expertise. Energy effi ciency is something we’ve done since the beginning. Onsite trouble shooting is another specialism.And a major part of our business is alternatives, e.g. interpreting the standards that are out there for hydrocarbons and then how to practically apply those standards to fridge systems, when they were originally written for large petro-chemical plants.

OUT AND ABOUT54 OUT AND ABOUT


Out and About with Will Hawkins

I met MD, Ian Sams, and Sales Director, Guy Hutchins, who

updated me on how Eaton Williams continues its success.

Eaton Williams has been around since 1936, starting in Edenbridge, Kent, and now with its main factory in Stoke-on-Trent. The company boasts 340 employees and a £30 million annual turnover. The business makes its money from making humidifi cation solutions (£4m pa), custom air conditioning units, produce & cellar cooling, air handling units, air distribution and data centre centre cooling solutions (£4m pa). Also, the company has a strong service business.

They have some impressive clients. Their ‘Server Cool’ data centre cooling business includes Facebook, Vodafone, NASA and IBM. When the Large Hadron Collider was built in Switzerland, Eaton Williams provided the data centre cooling for the project.

Eaton Williams is now owned by the US company, Nortek ($2.5bn turnover pa), which makes nearly 70% of its sales from heating, ventilation and air conditioning markets. Eaton Williams is part of the ‘Custom Engineered Solutions (CES)’ division, which will soon be called ‘Nortek Air Solutions’.

Eaton WilliamsWhen most people are winding down for Christmas, ACR Journal editor, Will Hawkins, was on the road visiting companies to hear about their news. Data centre cooling was the common theme in the visits.Here is what two businesses in this sector have been working on recently.

Ian and Guy joined the business to make Eaton Williams stronger through making their brands better known and to grow their market share. Their brands include VAPAC, Edenaire, Qualitair, Moducel, Colman and Server Cool.

Ian Sams said, “Eaton Williams has solid businesses within the group. But, we have not been acting as a group to help our customers. We are changing that by connecting our brands to provide better solutions.”

“Our service business is strong and, if necessary, we can and do act as a small contractor if it suits the requirements.”

DATA CENTRE COOLING

We got onto the topic of data centre cooling, and indirect evaporative cooling (iDEC), a cooling solution specifi cally for data centres.

“Key issues for customers for data centre cooling solutions are the size and weight of the equipment, its energy effi ciency and water usage,” said Guy Hutchins.

”Also, telecoms companies use direct cooling in their data centres. But, some customers have concerns about using outside air to cool their data centres because of the risk of contamination.”

This is where iDEC has an advantage. There is no risk of a data centre being contaminated by, say, pollution or fumes from the outside air because of the indirect nature of the cooling, as the name suggests.

Guy Hutchins added, ”Possibly half of the [data centre] market is moving towards indirect evaporative cooling systems. But, there will still a market for CRAC (computer room air conditioning).”

< Server Cool

(In fact, Eaton Williams has two CRAC systems, namely its Flexaire range and the more modular IPAC range, which is more customisable than the Flexaire range.)

We looked at one of the iDEC systems being developed and tested for a customer in their warehouse. When you see the size of an iDEC, you understand why space is a challenge in data centre (DC) cooling. You need a lot of air when it is the main refrigerant to cool your DC. The high volume of air means big units to handle it.

This is where the Eaton Williams designers have come up with a neat solution which manages to pack an effi cient indirect cooling system into a small space which is highly effi cient.

Next, we looked at the ‘rear door cooling’ systems the business makes. Eaton Williams works with a number of OEMs building systems to cool server chips. The clients include Fujitsu and HP. They export 80% of their equipment.

< Unit for i360 i360 DEVELOPMENT IN BRIGHTONFinally, the company is in the middle of designing the air conditioning system for the i360 tower in Brighton. The tower, designed by the people who created the London Eye, needs a special air conditioning system for the capsule which will take passengers up 138 metres above the town on Britain’s south coast. That is quite a challenge. But, Eaton Williams is confi dent in its plans to make it happen. ■

< Controls Assembly The last time I visited Airedale, the Leeds based

precision air conditioning and data centre cooling manufacturer, around 18 months ago, it was three weeks before a fi re partly destroyed their factory. I went back to see how they were getting on since that disaster and met MD Clive Parkman, Operations Director, Anthony Cole, Technical Director, George Hannah and their test and development experts, David Wilks and Mike Peachey.

I asked Clive Parkman how the business had been aff ected by the fi re: ”At the time, we had a plan to be up on our sales by 20% on the previous fi nancial year. We are on track to achieve that target. In eff ect, we lost three months of sales because of the fi re.”

He continued, ”Our customers were loyal.

When they heard about the fi re, they asked when we could deliver and 88% of their orders stayed with them. The other 12% had to go elsewhere because of project deadlines they had to meet.Since then, they have all come back to us.”

The fi re happened when a TurboChill system containing R1234ze caught fi re. There was a rumour that it was because of the ‘mildly

fl ammable’ refrigerant. However, that was proven not to be the case when it was clear that the condenser containing it had burnt but not exploded.

They lost their assembly area and coil plant in the fi re. But, their suppliers stepped in and loaned them equipment to use in the temporary factory.

Did the fi re cause any job losses?“We have only had two employees leave the business as a result of the fi re and that was because the commute to the current, temporary factory. The employees rallied together and there was almost a ‘wartime spirit’ among us all to make the best of it and to keep helping our customers.”

The company moved to a temporary factory in Leeds. It was soon kitted out and running again within weeks. I walked around the factory with Anthony Cole to see their team at work. Judging by that tour, Airedale is a healthy business with no shortage of orders.

Ironically, Airedale grasped the fi re as an opportunity to make big improvements in its business. Their insurance policy enabled them to invest in new equipment and systems. They now have the latest design systems and scheduling software in place. This makes it easier and faster for them to test out new ideas, and to get them to market quickly.Airedale Smartcool SR unit

FOREIGN AFFAIRSThe fi re has not stopped the company from its business development plans. Airedale is busy in the Middle East. It recently ran a training course for 90 contractors, consultant and end users from its business unit in Dubai.

“Many of our existing customers had never heard of products and services. For example, our chiller range was new to them until we ran the course,” said Parkman.

Most of their customers in the Middle East are interested in energy effi ciency. Buying the latest technology from Airedale is very aff ordable for them. It is more than just the lower running costs of the new products for their customers.

What is next? Airedale is working on the future too. Direct chip cooling is one exciting area their research team is working on. It looks like there will be more adiabatic cooling and air handling solutions too. Like many manufacturers in the industry, energy effi ciency, low GWPs and increased reliability are demands Airedale is reacting to create new products for their customers.

But, the big news will be in about a year when Airedale opens it new factory which will increase its capacity. It is a company that really has risen from the ashes when many would have collapsed. ■

<

Being more energy effi cient than their competitors is good for their business and prestige.

Airedale’s British brand (albeit owned by an American business) is also popular among their customers.

“Being British is an advantage where we do business in the Middle East. We have a head start on competitors from India or Korea, for example,” stated Parkman.

TRAINING & APPRENTICESHIPSAnother important part of Airedale’s business is training and apprenticeships. They have 17 apprentices working for them now and they take on one or two graduate engineers a year too.

Air conditioning technology is increasingly technical and attracting young engineers into Airedale and the wider industry is a challenge.

How do you make the air conditioning and refrigeration industry attractive?Clive Parkman explained,”We compete against companies like Jaguar and Land Rover for apprentices. They are compelling for young people to join because they have strong brands. But, they only usually get the opportunity to work on one aspect of a product. With AIredale, our apprentices are involved in the whole project. They get much wider experience with us. Our apprentices fi nd it very satisfying.”

Fujitsu launches new two-pipe rangeFujitsu is updating its two-pipe heat pump VRF o� ering with the launch of the new Fujitsu Airstage V-III range with more sizes and numerous new features.

The new range replaces the fi ve-year-old V-II and adopts many features from the latest three-pipe VR-II equipment.

While the popular V-II range had fi ve outdoor models ranging from 22.5kW to 45kW, the V-III has an additional 50kW model, with all sizes now using a single DC compressor, rather than the two that were used in the previous 40kW and 45kW models. This results in lower starting currents and improved part-load performance.

The extra model provides additional combination options up to 150kW, a substantial increase on the previous 135kW maximum.

Almost all EER and COP rates in the range have been improved, with the 22.5kW unit having a heating COP of 4.84 and a cooling EER of 4.31.

J & E Hall’s new beer cooler cuts energy bills by up to 40 per cent

J & E Hall’s new ambient beer cooler can cut energy bills for cellar cooling by up to 40 per cent. The unit uses free cooling to allow beers to be stored at a perfect temperature during the winter months.

The ambient beer cooler operates when it is cold outside at temperatures under 8°C. It will switch o� the main refrigeration cellar cooler system while it draws cold air from outside – cutting energy bills and saving money. When temperatures rise above this level it will revert back to the main refrigerated cellar cooling system.

“The beer cooler’s green credentials speak for themselves,” comments J & E Hall Product Sales Manager Tony Twine. “It’s a plug and play product which will make a signifi cant impact on energy bills for pubs, clubs, restaurants and breweries.”

Hello and welcome to the second instalment of the TF Solutions AdvICE Men column.

In the last issue of The ACR Journal, we invited you 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. Our knowledgeable team has already started receiving questions from you and hope to cover many of these queries in future issues.

This month, we’ve chosen to look at a problem faced by Mr C Walker who writes:

“On numerous occasions I have been called to repair a blown fuse on various evaporator PCBs. It’s always costly and frustrating for the customer and often causes system failure for weeks on end. Surely there must be a short cut way to prevent this from happening in the future? “

Lewis Jones, Technical Support Engineer at TF Solutions says:

“It’s interesting that Mr Walker has asked this question as it’s a problem that we see time and time again with engineers out in the fi eld. In most cases, blown fuses are

switched fuse spur is fi tted and this will serve two purposes. Firstly, fi tting the switched fuse spur will allow a point of separation enabling the engineer to be able to isolate the unit and work on it safely and let’s be honest, when we’re up a ladder, going to the roof, an unmarked fuse board is a nuisance!

Secondly, the fuse in the spur can be easily changed to suit the evaporator’s current requirements. Installing an isolator is good working practice and an electrical safety requirement. For the sake of an extra half an hour of installation time and a few more pounds to cover materials, the engineer can save time and money in the long run, not to mention preventing the customer from experiencing system down time. It can take weeks to order and replace a new PCB and multiple site visits to fi t the new part and ensure everything is running smoothly. A blown fuse can be changed in seconds making it a much more eff ective solution all round.”

We hope that you’ve found our handy tip useful. Please keep sending your questions to [email protected] or give us a call on 0161 429 5917 and we’ll be happy to answer your questions. We will be back again in the March issue.

Arctic Hero Fundraising Update

In our July/August issue we reported on ACR Today’s sponsorship of a charity drive to the Arctic by

Max Halliwell of Mitsubishi Electric. Max drove to the Arctic Circle in a 29 year old Porsche 944 within a period of 84 hours as a fundraiser for Help For Heroes.

Funds are still trickling in, and the total raised is just shy of an incredible £80,000!

Max’s next charity fundraiser, in aid of Save the Children, is a 550k cycle ride across Cambodia and Vietnam with fellow Mitsubishi Electric Staff and a group of clients. The fund where the money will be directed is the emergency fund for the ebola crisis. The group departs on 12th February.

The trip is funded by Mitsubishi Electric and any donations will go direct to the charity.

Amongst those who have already sponsored Max’s bike ride are One Planets Consultants, Rolton Group, TSG Building Services and Heat Pumps Today magazine.

ANOTHER LONG SERVICE ACHIEVEMENTFOR AIREDALE EMPLOYEESAiredale International, established in 1974, is extremely proud of its loyal workforce which it attributes as the single biggest factor in its success.

This year the manufacturer rewarded more than 35 individuals at an annual luncheon where they were joined by their managers and Airedale directors. The group of employees from all areas of the business, had clocked up a total of 810 years’ service between them, equivalent to an average of 23 years each.

Managing Director, Clive Parkman adds:“Our people really have put Airedale on the map and have been behind the many ‘fi rsts’ Airedale has achieved over our 40 years in business. We’re not perfect but we’ve been careful to retain a family culture and will continue to do so as we carry on growing. By creating the right environment for individuals at all levels to succeed at what they do and provide a way for them to progress their careers, as well as enjoy their time at work, we’ve been able to attract and retain a team of talented, committed people who together form a very successful team. I would like to thank each and every one of them for their loyalty to Airedale.”

The photograph shows Managing Director Clive Parkman (centre right) presenting machine operator Steve Smith with his certifi cate for 35 years’ service. Other Airedale employees pictured collected awards for 10, 15, 20, 25 and 30 years of service.

A professional 41 piece socket wrench set from ITE (UK)

In November 2014, as the ACR team travelled around the UK to get stories and features that

make this magazine so popular, we spotted a Flowrite van at Whitely Retail Village,

Southampton. The prize was claimed by James La� erty, Air Conditioning Service Engineer at

Flowrite Services.

Sometimes readers send in vans they have spotted. This photo was taken on Tuesday 6th January 2015

at Junction 7/8 of the M1 Southbound between Hemel Hempstead and St Albans. If you think this is your

van, give me a call or drop me an email, with your van registration, which I alone know.

Sentinel Commercial expands with appointment of Technical Sales Engineers Sentinel Commercial is on a trajectory of rapid expansion thanks to increasing demand for best practice water treatment solutions in the commercial HVAC market. The company, which has been providing water treatment support for commercial cooling and heating system applications for just over four years, has welcomed two more technical sales engineers to its expanding team.

Adam Purnell and Craig Milner, who cover the South and Midlands areas for Sentinel Commercial respectively, o� er an impressive 35 years’ experience in the water treatment and HVAC industries between them.

Ian Barnes, Head of Sentinel Commercial, commented: “There is a clear trend showing increasing demand for high quality water treatment in the commercial market, which historically has been plagued with poor water treatment practices, leading to costly scenarios such as premature system breakdown, downtime, and reduced energy e� ciency. These appointments are a refl ection of Sentinel Commercial’s aspiration to grow through a best practice approach to customer support, and both Craig and Adam have the expertise and experience to ensure we meet our ambitions.”
