Intelligence

Toshiba’s SMi system now has added intelligencewith the Intelligent Power Drive Unit (IPDU), thelatest inverter technology.

Qualifies for Enhanced CapitalAllowance

As a variable-speed drive system this product is onDEFRA’s Energy Technology Product list andentitles the purchaser to a tax benefit under theECA scheme (applies to the UK only). For furtherdetails refer to the following website:www.eca.gov.uk

Ozone-friendly refrigerant

All products produced at Toshiba’s award-winningPlymouth factory use R407C non-ozone-depletingrefrigerant.

The VRF Heat recovery system(MAR-F-105HTM8-PE)

Toshiba Air Conditioning is proud to introduce theSMi system, a three-pipe, heat recovery systemoperating on R407C, and incorporating the latestinverter drive technology. The letter “i” stands forthe added intelligence of the Intelligent PowerDrive Unit (IPDU). SMi delivers the output of theprevious Super Multi system in a smaller, quieter,more sophisticated and energy-efficient outdoorunit.

The Right Solution

The Toshiba SMi is a sophisticated system thatsuits a broad range of commercial air conditioningapplications. It can simultaneously heat and cooldifferent zones in a building to meet occupantrequirements. Heat recovery systems allow hot orcold air to be redistributed for increased energyefficiency.

The aesthetics of the outdoor unit match theToshiba MMS 2-pipe range, making anycombination of the two systems on-site lookattractive.

General Information

Benefits of VRF

The Variable Refrigerant Flow (VRF) productsegment is one of the fastest growing areas ofthe air conditioning industry due to the inherentflexibility of the system.

Specifiers are selecting this type of airconditioning product because it provides theeconomy and stability of a network system withthe versatility of an independent system.

As SMi is a heat recovery system, this allowsheat being removed from one indoor unit to betransferred to another indoor unit that has aheating demand, thus improving the overallefficiency of the system. Heat recovery systemsoffer simultaneous heating and cooling thusproviding complete comfort, making the systemideal for variable load situations such as hotelsand offices.

VRF systems are compact and discreet whichmakes them ideal for applications when the airconditioning system is being retro-fitted to theexisting building.

Since the air is conditioned locally there is noneed for large ductwork throughout the buildingfor the flow of heated/cooled air. Only smallpipes are necessary to carry the refrigerant tothe desired location. Because the air is cooledto the desired temperature at the point of use,the end user gets rapid, precise temperaturecontrol.

When integrated with control systems theperformance can be optimised to achieve ultralow energy consumption, particularly whenthere is high diversity in the capacity demand.

Benefits of the SMi System

Refrigerant Detection and ContainmentSystem (RDC)TM

As an additional precaution an optional refrigerantdetection system is available. This senses the airquality within a room and if refrigerant levelsexceed preset limits, it will emit an audible alarmand transmit a signal that can activate auxiliarysolenoid valves, isolating the indoor unit from thesystem and preventing further leakage to theenvironment.

HFC RefrigerantToshiba is committed to designing andmanufacturing products that will not harm ourenvironment. All of our European air conditioningproducts use HFC refrigerants that have zero ozonedepletion potential.

Energy EfficiencyThe inverter system reduces the energyconsumption by adjusting output to match capacitydemands.Toshiba’s research team has led the wayin the development of inverter technology andcontinues to deliver products that are best in class.

General Information


Interactive ControlsThe system is available with Interactive Intelligence,Toshiba’s range of sophisticated controls.The user-friendly software with a Windows® based platform allowsmanagement of up to 1,024 indoor units (up to 64 zoneswith 16 units per zone).The entire air conditioningnetwork can be programmed to meet the end user’sneeds.These controls are interactive; two-waycommunication enables your system to send you regularupdates through the internet via your PC or mobiletelephone. Service engineers can be notified of systemstatus and any necessary action can be taken before itbecomes evident to the user.

Energy Monitoring• The power consumption of each individual indoor

unit can be monitored allowing energy bills forshared systems to be sub-divided across multipleoccupants.

• Building managers can identify high-use systemsand investigate potential opportunities for energysavings.

• An energy meter connected to each outdoor systemmeasures its usage (kW/h) and the energyconsumption is proportioned to the indoor unitsbased on their capacity demand.

• A billing package is already included with thesoftware, which allows billing on a multiple-tariffbasis.

Internet AccessThis feature is ideal for building management services with more than one site.• Remote monitoring and control is possible for multiple users at any one time using Microsoft Internet

Explorer®

• Various levels of access are permitted for security

• Immediate access to operating conditions and historical performance. Allows rapid response to userenquiries.

DiagnosticsThe network can also be linked to Dyna Doctor II,Toshiba’s system interrogation software allows theservice engineers to gain access to critical system parameters to monitor the functions of the unit.

General Information


Applying the SMi System is easy. The following flowchart outlines the basic steps of the process, whichare typical for almost all air conditioning applications. This manual is structured with separate chaptersfocusing on each of the steps along with a separate chapter on each type of indoor unit. We have alsoincluded a chapter which outlines an example of an SMi application.

As with all air conditioning applications, proper zoning is important.To maximise the benefits of heat recovery, indoor units connectedto a common system should have opposing loading characteristics.

Each of the indoor units will be powered by the outdoor unit. Controlwiring requirements will be determined by the controls selection.

The controls selection is dependent on the specification. Toshibahas a wide range of control systems available and has collaboratedwith customers on the development of unique systems to meetspecific application requirements.

Indoor unit capacity will be adjusted based on the expected lengthand height of pipe runs and environmental conditions.

The piping network for the indoor units will be based on thepositioning of the Multi Controllers and building layout.

Indoor units are selected based on the predicted heat load as wellas the style and layout of the space to be air conditioned. Airdistribution and sound level characteristics may also be factors forconsideration.

Air Distribution Control

Conditioned air can be distributed through 2, 3 or 4 sides of the unit to optimise the flow distribution in aroom. Insulation blocks are included with the unit to close off the airflow to certain sides of the unit. Thediagram below defines which sides of the unit may be closed for each of the capacities.

Choose the number of airflows that are required, depending on the shape of the room and the location ofthe indoor unit.

In addition, a motorised louvre facility allows the air to be directed in either a pre-set or a sweep pattern.Cassettes also have a branch duct facility for better air distribution in irregular shaped rooms. Thecombination of these two features gives the occupants total control over air movement within the room,via an easy-to-use remote controller.

• It is not possible to block the airflow from thelonger sides of the unit (RAV 364/464 UH-PE).

• Insert insulation blocks, which are supplied asaccessories, at each side where the airflow isnot required as shown in the diagramopposite.

Design Features

Flexible Air DistributionConditioned air can be distributed through 2, 3 or 4 sides of the unit. In addition, a motorised louvrefacility allows the air to be directed in either a pre-set or a sweep pattern. Cassettes also have a branchduct facility for better air distribution in irregular shaped rooms. The combination of these two featuresgives the occupants total control over air movement within the room via an easy-to-use remote controller.

Fresh Air FacilityAn additional advantage of Toshiba’s 4-way cassettes is that outdoor air, as well as conditioned air, canbe introduced into the room. (Tempering to 15°C minimum is recommended.)

Quiet OperationNoise levels have been reduced dramatically, thanks to the specially designed fan inlet that smoothes theairstream as it flows into an aerofoil fan and aerodynamic louvres.

Easy to Install and MaintainThe 4-way cassette can be concealed within most ceiling voids, with an ultra-thin 20 mm grille. This one-piece panel is easy to install. Its surface is easy to wipe clean, a feature it shares with the synchronisedlouvre blades. The long-life washable filter also minimises maintenance.

Connection to the unit is via a 1” BSP maleconnection – to ensure a waterproof seal, PTFEthread tape should be used. The maximum lift ofthe condensate pump from the drain outlet is 360mm and the maximum overall lift from theunderside of the ceiling to the centre of the drainpiping is 600 mm. These values must not beexceeded, otherwise unit flooding will occur whenthe drain pump is switched off.

* Heat Insulator:Polyethylene foam (thickness 6 mm)

** Piping Material:Hard PVC pipe nominal diameter inside Ø20 mm

Four-Way Cassette

Drain Piping

PrecautionsEnsure that the entire indoor drain piping is correctly heat-insulated otherwise condensation may result.Also, insulate the section which connects it to the indoor unit.

If nylon cable ties are used to secure the insulation, take precautions not to over-tighten them becausedeformation of the heat insulation will reduce its effectiveness.

Take care not to apply excessive force or pressure at the unit side where the drain piping exits the indoorunit.

The drain piping must be placed on a downward gradient (1/100 or greater) and there should be noupward or downward curves in the pipe which obstruct the drainage, unless a drain pump is employed.

The drain pipe should be sufficiently supported to prevent warpage.

When one drainage system is used for a multiple of indoor units, install the piping as shown below:

Air Distribution


Design FeaturesWhere ceiling void space is limited, a common problem with retrofit applications, Toshiba has the solutionwith its range of ultra slim-line 2-way cassettes.

Adjustable Air DistributionConditioned air is distributed through both sides of the unit. A motorised louvre facility allows the air to bedirected in either a pre-set or a sweep pattern, giving occupants control over air movement within theroom via an easy-to-use remote controller.

Quiet OperationA 3-speed fan controls the airflow volume automatically, or can be set manually. Even at the highest fanspeed, the unit is quiet in operation.

Easy to Install and MaintainThe 2-way cassette is only 190 mm in height, so can be concealed within a very shallow ceiling void,exposing a grille of only 25 mm in height. A long-life washable air filter is included for easy maintenance.

Fan Characteristics

Design Features

Whatever the shape of the room, ducted units create uniform temperatures throughout. The unit itself istotally concealed, usually within a ceiling void. Cool or warm air is then ducted into the room throughdiffusers discreetly positioned in the walls, floor or ceiling. These units can also be connected to anoutdoor air supply. (Tempering to 15°C is recommended.)

All-round ComfortOperated by an easy-to-use remote controller, Toshiba’s ducted units provide perfect comfort throughoutthe room without leaving cool or hot spots.

Design FlexibilityAny style of air diffuser can be used, greatly increasing the scope for attractive interior design within theroom. Moreover, should the room layout change, the diffuser’s position can easily be moved with the veryminimum of disruption. Greater design flexibility can be achieved with the option of return air to theunderside or rear of the unit. The front spigot plate can be easily removed to allow for the connection ofsquare ductwork. An optional remote sensor, 10 m in length which allows the return air sensor to belocated within the room.

Fan Characteristics

Design FeaturesThese compact floor-standing ‘chassis-only’ units are particularly suitable for areas such as partitionedoffices, where attachment to a ceiling is impracticable. The units occupy minimal floor space, so are idealfor siting against perimeter walls in open plan offices, banking halls, retail sites and similar areas.

Design FlexibilityUnits are supplied in ‘chassis-only’ form, so they can be concealed in casings specially built to blendunobtrusively with the room decor. They have top or front air outlet options for increased applicationflexibility.

Very Simple to InstallBecause these are floor-standing, wall-fixed units, installation is not only extremely simple and fast butcan also be done without spoiling existing decorations.

AirflowA three speed fan controls the air volume automatically, or can be set manually according to therequirements of the room occupants.

Easy to MaintainThe unit includes easy-clean integral filters.

Design Features

These slim floor/low wall fully cased units are especially suitable for areas such as partitioned offices. Theunits occupy very little floor space, and are ideal for siting against perimeter walls in open-plan offices,banking halls, retail sites and similar areas. The units match the ceiling model to provide the perfectsolution where both configurations are required.

Elegant Cost-effective SolutionsThe unit provides efficient cooling or heating and is fitted with an adjustable louvre for uniform airdistribution.

Very Simple to InstallBecause these are floor-standing, but wall-fixed units, installation is not only extremely simple but can bedone without spoiling existing decorations.

Fresh Air FacilitiesA knock-out panel is located on the bottom of the unit to allow for up to 10% fresh air.

Capacity Correction

Once the style and size of indoor unit has been selected, a check must be made to see if expectedtemperature conditions and estimated piping configuration has an affect on the preliminary choice.Reselection may be required after correcting.

De-rating Indoor UnitsAll indoor units have a standard capacity code setting that relates to the maximum amount of coolingavailable from each indoor unit. Adjusting the capacity code (called de-rating) can reduce the output ofthe indoor unit, but increases the sensible heat ratio (SHR). The capacity code is set using the rotaryswitches in the respective Multi-Controller and controls the maximum setting of the pulse-modulatingvalve (PMV). The available settings and respective rated total cooling duties (in kW) by unit are asfollows.

Cooling Duty

Correction for Temperature – CoolingThe cooling duties stated so far relate to environmental conditions of 35°C (db) ambient, 27°C (db)internal and approximately 47% relative humidity. This condition is generally known as T1 (or Eurovent)conditions. To give assistance when designing to any global conditions, graphs are provided to correct forthe full range of temperatures. For convenience, we have included calculated duties at common designconditions (ambient and internal), with respective sensible duties at all settings (standard & de-rated).See tables C1-C12.

Maximum allowed lift (outdoor unit below indoor unit) is 20 m. Correction for length and lift is required.

Maximum allowed drop (indoor unit below outdoor unit) is 50 m. Only correction for length is required.

These factors should be applied to the cooling (only total, not sensible) obtained from the temperaturecorrection tables or graphs.

Pipe runs do not significantly affect the sensible cooling duty, so a longer pipe run gives a reduction inlatent cooling and consequently an increase in SHR. However, a reduction in sensible duty mayeventually occur, by virtue of the fact that the sensible cooling duty can never exceed the total coolingduty.

Correction for Indoor/Outdoor Loading – Cooling

If an outdoor unit is overloaded with indoor units that total more than 100% of the outdoor unit capacity,then the indoor units will not be able to achieve their rated capacity. As a simple theoretical example:

If ten RAV-105’s (capacity code 2) indoor units are connected to an MAR-F105HTM8 outdoor unit ithas 100% indoor/outdoor loading and 2.5kW would be expected from each the indoor units.

If twelve RAV-105’s (capacity code 2) indoor units are connected to an MAR-F105HTM8 outdoor unitit has 120% indoor/outdoor loading and consequently, the indoor units would not be able to produce2.5 kW if they all asked for cooling at the same time (0% system diversity). Only 2.08 kW could beexpected from each of the indoor units.

In reality the outdoor unit can give more than 100% of its rated capacity when pushed, as shown in thegraph below. The graph can be used to determine the output of each indoor unit when the total systemcapacity code is above 20.

When correcting for an indoor unit the correction for total and sensible cooling is given by:

Capacity (%) of Outdoor Unit when loaded to X%

X%

Using the example above, this means than the indoor units will give: 107%/120% = 89%. This equates to2.23 kW.

Correction for Airflow Variation(ducted and chassis units only) – heating & cooling

Cooling and heating capacities will be affected by volumetric airflow in ducted units. Resistance inducting, which is in turn determined by ductwork length and design, affects the airflow. After a resistancehas been calculated, the corresponding volumetric flow can be obtained from the fan curves included inthe indoor unit section (chapter 5).

The airflow variation ratio is given by the corrected flow due to resistance divided by the standard airflowof the unit. The capacity correction value can then be read off the graph.

Guideline estimation of diversity:

Type of air conditioned space Diversity

Single space with a single aspect 0%

Single space (group control) with multiple aspects 10%

Multiple spaces (individual control) of similar construction, uses and aspects 20%

Multiple spaces (individual control) of similar construction, uses but with different aspects 25%

Multiple spaces (individual control) of similar construction, but with different uses and aspects 30%

Please note that diversity is difficult to predict and is not an exact science, but can be estimated usingheat gain/loss calculation packages. Generally speaking 35% diversity (providing 65% of the maximumcooling/heating requirement) is considered to be the upper limit of diversity to assume in comfort coolingsituations.

Capacity Correction

Outdoor Unit Selection

After all applicable correction factors have been applied to select the correct indoor units; the number ofoutdoor units can be determined by the sum of the indoor unit capacity codes as follows:

One MAR-F105HTM8-PE can be selected under the following conditions:

Sum of indoor network No. of Multi Controllers Loading(capacity codes)

≤ 20 ≤ 4 ≤ 100%

21 to 27 1 105-135%*

21 to 32 2-4 105-160%*

* Note: As these loadings exceed the 100% threshold, checks must be made to ensure that the loading ofall the indoor units is acceptable for the total requirements of all the areas served by the system as awhole, when assuming the appropriate amount of diversity. Refer to the previous section on “Correctionfor Indoor/Outdoor Loading - Cooling” on page 59 and/or “Correction for Indoor/Outdoor Loading -Heating” on page 62.

Diversity

As different parts of a building are likely to have their peak heat gains/losses at different times of the day,maximum cooling or heating is rarely required from all units simultaneously; therefore diversity issometimes applied. The ambient temperature is not constant during a 24-hour period, so invariably asystem will never be required to run at full-load for 24 hours a day. Usage is another factor to considerwhen applying diversity: meeting/conference/interview rooms are rarely all used all day and places likecanteens are only used during the lunch period. Obviously when these areas are being used, buildingoccupancy is shifted from room to room, so metabolic and small power gains also change. It follows thenthat the greater the number of areas served by a particular system, the greater the chances of havingsome diversity. The potential for diversity and heat recovery is also increased when there is a largegeographical spread of areas being served by a system.

Multi Controller

Installation

The three pipes from the outdoor unit are connected to the Multi Controller which then controls the flow ofthe refrigerant to each of the indoor units. It also acts as a wiring centre for the indoor units, making theprovision of a separate power supply unnecessary. The Multi Controllers have three (RBM-Y1034-PE) orfour ways ((RBM-Y1044F-PE). Any outlets that are not used can be capped or valved off. Whilst all of thesuction pipework within the Multi Controller is insulated to prevent condensation forming, when any unit iscooling, as a precaution a heater element is fitted to the base of the Multi Controller to evaporate anymoisture that may collect in the base. This makes the provision of a separate condensate drainunnecessary.

As standard, a maximum of two Multi Controllers can be connected to the outdoor unit, however by usingthe dual interface (RBC-DIF1-PE) this can be increased to a maximum of four. Wiring from two MultiControllers is taken to the dual interface, and one cable is then taken to the outdoor unit.

The location of the Multi Controller should be carefully considered to ensure good all-round access,should any of the valves or sensors require replacing. If the Multi Controllers are to be installed above afalse ceiling, then an access panel bigger than the Multi Controller will be required.

Precautions

Avoid installing the Multi Controller in the following locations:

• Where rainwater may penetrate the unit.• Where the weight of the unit cannot be supported.• Where it is not level.• Where there is high temperature under the ceiling or where a high-temperature atmosphere may be

produced.• Where there is equipment that generates high frequencies.• Where it is near devices or wiring which may give off electromagnetic interference.• The base of the unit will reach temperatures of approximately 50°C. Do not place heat sensitive

objects close to the base of the unit.

* Branches to be capped off as required.** Any Multi-Controller connected to a Dual Interface has a maximum connected capacity code limit of 13.

It may be that site requirements will determine alternative arrangements for a given number of indoorunits. For example, if there are four indoor units split across two floors, it may be more convenient forpiping purposes to offer a 3-way Multi-Controller for each floor, rather than one 4-way Multi-Controller.

Twinning

If two identical units are supplying the same space it may be possible to twin the units from one branch ofa Multi-Controller. These two units would act as master and slave, sharing control inputs and wouldtherefore both have the same mode, set point, fan speed etc. The capacity code is set using the rotaryswitches in the respective Multi-Controller as follows:

Indoor units Capacity code settings available

Please note that RAV-36 and RAV-46 units cannot be twinned.

This is a useful means of reducing the required quantity of Multi-Controllers. For example: If nine indoorunits are to be connected to one outdoor unit, but two of those indoor units are supplying the same area,it may be possible to twin the units and install two 4-Way Multi-Controllers, rather than three 3-Way Multi-Controllers.

Insulation

All piping will need to be thermally insulated with Class “O” or equivalent, to local regulations and suitablefor the ambient temperature experienced.

Insulation shall be as follows:

Within buildings:

Pipe diameter Insulation wall thickness1/4 to 1/2 9 mm

5/8 to 1-1/8 13 mm

Where the discharge pipe is external, a minimum of 25 mm insulation will be required to preventexcessive heat loss through the insulation, resulting in poor heating performance.

Where insulated refrigerant pipes penetrate dividing fire-resistant walls and/or ceilings the pipework shallpass through sleeves and the space around the pipes shall be sealed with an approved material toprevent the spread of fire.

All external pipework shall be suitably protected from the weather, vermin and UV degradation.

Additional Refrigerant

The outdoor units are pre-charged with 19 kg of HFC R407C refrigerant. This is suitable for 5 m of mainpiping (P1). Additional refrigerant will be required as follows - the weight required determined by thelength of liquid pipes, in accordance with the table below.

Main piping (P1) 0.190 kg/m

Sub-piping (P2) 0.125 kg/m

Branch piping (P3) 6.4 mm (1/4”) OD 0.030 kg/m

Branch piping (P3) 9.5 mm (3/8”) OD 0.045 kg/m

For more information on additional refrigerant see the SMi installation manual.

Introduction

The control system that the SMi system is based around, is a serial link that combines communication tothe indoor and outdoor units.

In the case of SMi system, the network controlling device is connected to the indoor units althoughexisting SMi products can be combined onto the same platform (except for RAV cooling only splitsystems).

The controls may be classified as local or network, and any indoor unit may be controlled by either, or acombination of both (including MMS and RAV 4 and 5 series heat pumps).

Local Controls (ABC)Refers to a controller that will normally be used in the conditioned space.

Network Controls (XY)These controllers are either centralised for control of a number of indoor units, or a interface which allowsconnection to the Toshiba Windows ® control package or another BMS option.

For SMi system, the network controls are connected to the indoor units. It is possible to connect the SMioutdoor unit to the network.

System ControlThe system control data is distributed with the power cables from the outdoor unit used in the serial cable,not via a separate network.

NB: Capacity and power specifications relate to a system selected with equal outdoor and indoor unitcapacity; those in parenthesis are for a system configured with the maximum number of indoor units ratedin total at 135% of the outdoor unit capacity.

The mains cable must be selected for the particular loading and in accordance with national, local andinternational standards and in particular site requirements.

A four-pole isolator is provided in the outdoor unit for the termination of the mains supply cable. Caremust be taken when wiring the cable conductor into the isolator to prevent damage to the printed circuitboards and transformers.

Power supply for the Multi-Controller(s) is derived from the outdoor unit by designated terminal blocks. A20 A fuse provides protection for the Multi-Controller(s), and consequently the supply cable should besized accordingly. The Multi-Controllers in turn supply power to the indoor units.

Interconnecting wiring – outdoor unit to Multi-ControllersA suitable 3-core and earth cable(s) should be taken from the outdoor unit and routed to each Multi-Controller. A three-pole isolator should be provided at all Multi-Controllers.

Interconnecting wiring – Multi-Controller to indoor unitsA suitable 3-core and earth cable should be taken from the Multi-Controller to each of the indoor units. Athree-pole isolator should be provided at all indoor units. It is essential to ensure that indoor unit ‘A’ isconnected to the electrical terminals marked A1, A2, A3, indoor unit B to B1, B2, B3, etc. Incorrectconnection will result in system failure.

Precautions

This guide should be read and utilised in conjunction with official published regulations and codes ofpractice, be they local, national or international.

Each air conditioning system will have its own discrete power supply, with overload currentprotection. The electrical power will be supplied to the outdoor unit via the built-in isolator.

The indoor units will derive their electrical power from the multi controller, and they in turn will derivetheir power from the outdoor unit.

The interface kit will derive its electrical power from the outdoor unit.

The circuit protection device will protect the supply cable against overcurrent. The circuit protectionmust be selected having due regard to the compressor starting current, such that the supply cableswhen sized correctly, are protected.

The cable should be selected to match the nominal load of the system, in addition to the lossesassociated with corrections for length, temperature, impedance, etc. In accordance with local codesof practice.

Please refer to the unit’s nameplate and the relevant technical specifications to determine the correctpower supply.

1.A small single storey doctor’s surgery requires air conditioning, as follows:

Area Sensible cooling (kW)

Reception 4.80

Consulting room 1 1.45





Nurse 2.20

Total 14.25

Each area is to have individual control with the ability to heat or cool, on demand. The design conditionsare 27°C ambient and 23°C db internal (at 50% RH). The condenser will be located on the ground andhave an equivalent pipe run of 30 m with 5 m lift to the furthest indoor unit. Cassette units are requiredthroughout.

As we will be sizing on the sensible cooling a selection can be made straight from table C1 in section 11.This gives cooling duties at 27°C ambient. From the 23°C internal temperature column this selection canbe made:

Area Unit Capacity code Sensible cooling (kW)

Reception RAV-264UH 6 4.86

Consulting room 1 RAV-104TUH 2 1.49





Nurse RAV-134TUH 3 2.28

Total 19 14.59

Although sensible duties are not significantly affected by pipe run, degradation in performance willeventually occur after the latent cooling has been taken up by piping losses. From the table on page 58an equivalent pipe run of 30 m with 5 m lift gives a correction factor of 0.94. If this factor is applied to thetotal cooling figures in table C1 it can be seen that the sensible cooling is still below the total cooling. If ittranspires that the corrected total cooling is below the sensible cooling, then the actual sensible cooling isequal to the total cooling (SHR = 1).

As the total capacity codes are less than 20, one SMi condenser can be selected to run these indoorunits.

For seven indoor units, each requiring individual control, one 3-Way Multi-Controller and one 4-Way Multi-Controller can be used.

2.Various office areas require the following amount of cooling:

Area Total cooling (kW)

Managing Director’s office 1.90

Accounts 3.75

Finance Director 1.50

Meeting Room 5.00

Open Plan 8.00

Commercial Director 1.50

Reception 5.00

Total 26.65

Each area is to have individual control with the ability to heat or cool, on demand. The design conditionsare 28°C ambient and 22°C db internal (at 50%RH). The condenser will be located on a flat roof abovethese areas and have an equivalent pipe run of 40 m to the furthest indoor unit. Ducted units are requiredthroughout.

First we need to obtain the correction factor for piping losses on page 58. For a 40 m equivalent pipe runthe correction factor is 0.93. If we divide the cooling requirement for each area by this factor, the resultcan then be looked up in table C2 in section 11. This table gives outputs at 28°C ambient and from thisgraph the following indoor units can be selected from the 22°C column:

Area Unit Capacity code Cooling potential (kW)

Managing Director’s office RAV-104SBH 2 2.19

Accounts RAV-164BH 4 3.93

Finance Director RAV-104SBH 1 1.64

Meeting Room RAV-264BH 5 5.51

Open Plan RAV-364BH 8 8.74

Commercial Director RAV-104SBH 1 1.64

Reception RAV-264BH 5 5.51

The cooling potential is the maximum output obtainable from that particular unit at the design conditionswhen the outdoor unit is loaded up to 100% (code 20). As the capacity codes total 26, we will need tocheck that the total output of all the indoor units is still acceptable when a single SMi condenser is loadedto 130%.

The actual cooling output for each unit is calculated using the graph and formula on page 59. At code 26the condenser will produce 110% output. Therefore the indoor units will give 110%/130% = 0.85 (or 85%).This factor is then applied to the figures obtained from table C2 in section 11 along with the correction forpiping losses (0.93). The actual cooling duty shown for each indoor unit is the output when all units arerequesting maximum cooling at the same time.

Area Unit Capacity code Actual cooling (kW)

Managing Director’s office RAV-104SBH 2 1.86

Open Plan RAV-364BH 8 7.43

Commercial Director RAV-104SBH 1 1.39

Reception RAV-264BH 5 4.68

Total 26 24.77

At worst-case conditions the total system output is 24.77 kW. The total requirement is 26.65 kW. Thismeans that we are providing 93% of the total cooling requirement. The meeting room is unlikely to beused all day, every day and as each area will have individual control and similar uses, 7% diversity doesnot seem unreasonable, so one SMi condenser can be used. For seven indoor units, each requiringindividual control, one 3-Way Multi-Controller and one 4-Way Multi-Controller can be used.

3.A four-storey hotel requires air conditioning. Each floor has nine rooms and each room requires a ductedunit with 1.8 kW total cooling capacity when set at medium fan speed. The design ambient temperature is30°C and the required internal temperature is 21°C db (at 50% RH). The condensers are to be located onthe roof and each will have an equivalent pipe run of 60 m to the furthest indoor unit.

The piping loss correction factor for 60 m is 0.88 (from page 58), the correction for medium fan speed is0.96. If we divide the required amount of cooling by 0.88 and 0.96, we get a look-up value of 2.13 kW.From table C4 in section 11 we can see that a RAV-10 size unit is required. As ducted units have beenrequested, a RAV-104SBH-PE set on capacity code 2 will be offered for each room.

36 rooms in total require air conditioning. To get a rough idea about the minimum number of SMicondensers required, we can divide the 36 by the maximum number of indoor units that can be connectedto a single outdoor unit, which are 16. From this simple calculation, the minimum number of outdoor unitsis 3. If we then divide the total number of indoor units by 3, we know that each SMi condenser shouldhave 12 indoor units connected.

The total capacity code for each condenser will be 24 (12 x 2) and the total cooling requirement will be21.6 kW (12 x 1.8 kW). To check that the total output of all the indoor units is still acceptable when asingle SMi condenser is loaded to 120% the graph and formula on page 59 should be used. From thissection it can be seen that at 120% loading the SMi condenser will produce 107%. Therefore the indoorunits will give 107%/120% = 0.89 (or 89%). The actual indoor output if all indoor units are demandingcooling at the same time is:

2.28 kW x 0.88 x 0.96 x 0.89 = 1.71 kW

Therefore, at worst-case conditions, each SMi system will give 20.52 kW. The total requirement is 21.6kW. This means that we are providing 95% of the total cooling requirement. 5% diversity is acceptable fora hotel application, so three SMi condensers; each with twelve units connected can be used.

As there are only nine rooms per floor, each SMi condenser will have to supply indoor units across floors.Normally when there are twelve indoor units, three 4-Way Multi-Controllers would be used. In thisinstance it may be better to have four 3-Way Multi-Controllers connected to each outdoor unit. So systemconfigurations would be:

System 1 – Serving all of floor 1 and three units on floor 2.System 2 – Serving six units on floor 2 and six units on floor 3.System 3 – Serving three units on floor 3 and all of floor 4.
