4 General Information 1 Introduction Features Reduced weight, compact design with smaller footprint Optimised for use with the non-ozone depleting refrigerant, R407C Up to 16 individually controlled indoor units to one outdoor unit, with precise temperature control Easy to install and maintain High energy efficiency Unique capability to adjust the sensible heat ratio Latest inverter technology with the Intelligent Power Drive Unit (IPDU) The VRF Heat recovery system (MAR-F-105HTM8-PE) Toshiba Air Conditioning is proud to introduce the SMi system, a three-pipe, heat recovery system operating on R407C, and incorporating the latest inverter drive technology. The letter i stands for the added intelligence of the Intelligent Power Drive Unit (IPDU). SMi delivers the output of the previous Super Multi system in a smaller, quieter, more sophisticated and energy-efficient outdoor unit. The Right Solution The Toshiba SMi is a sophisticated system that suits a broad range of commercial air conditioning applications. It can simultaneously heat and cool different zones in a building to meet occupant requirements. Heat recovery systems allow hot or cold air to be redistributed for increased energy efficiency. The aesthetics of the outdoor unit match the Toshiba MMS 2-pipe range, making any combination of the two systems on-site look attractive. Compatible with RAV indoor units that can operate from 100% down to 10% of maximum rated capacity Up to 160% loading Low noise level Intelligence Toshiba s SMi system now has added intelligence with the Intelligent Power Drive Unit (IPDU), the latest inverter technology. Qualifies for Enhanced Capital Allowance As a variable-speed drive system this product is on DEFRA s Energy Technology Product list and entitles the purchaser to a tax benefit under the ECA scheme (applies to the UK only). For further details refer to the following website: Ozone-friendly refrigerant All products produced at Toshiba s award-winning Plymouth factory use R407C non-ozone-depleting refrigerant. 4

5 General Information Benefits of VRF 1 The Variable Refrigerant Flow (VRF) product segment is one of the fastest growing areas of the air conditioning industry due to the inherent flexibility of the system. Specifiers are selecting this type of air conditioning product because it provides the economy and stability of a network system with the versatility of an independent system. As SMi is a heat recovery system, this allows heat being removed from one indoor unit to be transferred to another indoor unit that has a heating demand, thus improving the overall efficiency of the system. Heat recovery systems offer simultaneous heating and cooling thus providing complete comfort, making the system ideal for variable load situations such as hotels and offices. VRF systems are compact and discreet which makes them ideal for applications when the air conditioning system is being retro-fitted to the existing building. Since the air is conditioned locally there is no need for large ductwork throughout the building for the flow of heated/cooled air. Only small pipes are necessary to carry the refrigerant to the desired location. Because the air is cooled to the desired temperature at the point of use, the end user gets rapid, precise temperature control. When integrated with control systems the performance can be optimised to achieve ultra low energy consumption, particularly when there is high diversity in the capacity demand. The Five Key Benefits of SMi Reliable Environmentally compatible Intelligent Versatile Economical 5

6 General Information Benefits of the SMi System Environmentally Compatible HFC Refrigerant Toshiba is committed to designing and manufacturing products that will not harm our environment. All of our European air conditioning products use HFC refrigerants that have zero ozone depletion potential. THE INVENTOR OF INVERTER-DRIVE AIRCON TECHNOLOGY Energy Efficiency The inverter system reduces the energy consumption by adjusting output to match capacity demands.toshiba s research team has led the way in the development of inverter technology and continues to deliver products that are best in class. Refrigerant Detection and Containment System (RDC) TM As an additional precaution an optional refrigerant detection system is available. This senses the air quality within a room and if refrigerant levels exceed preset limits, it will emit an audible alarm and transmit a signal that can activate auxiliary solenoid valves, isolating the indoor unit from the system and preventing further leakage to the environment. 6

7 General Information Benefits of the SMi System 1 Interactive Controls The system is available with Interactive Intelligence, Toshiba s range of sophisticated controls.the userfriendly software with a Windows based platform allows management of up to 1,024 indoor units (up to 64 zones with 16 units per zone).the entire air conditioning network can be programmed to meet the end user s needs.these controls are interactive; two-way communication enables your system to send you regular updates through the internet via your PC or mobile telephone. Service engineers can be notified of system status and any necessary action can be taken before it becomes evident to the user. Up to 64 zones (allowing up to 16 units per zone) Energy Monitoring The power consumption of each individual indoor unit can be monitored allowing energy bills for shared systems to be sub-divided across multiple occupants. Up to 16 gateway interfaces Building managers can identify high-use systems and investigate potential opportunities for energy savings. An energy meter connected to each outdoor system measures its usage (kw/h) and the energy consumption is proportioned to the indoor units based on their capacity demand. A billing package is already included with the software, which allows billing on a multiple-tariff basis. Internet Access This 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 user enquiries. Diagnostics The network can also be linked to Dyna Doctor II,Toshiba s system interrogation software allows the service engineers to gain access to critical system parameters to monitor the functions of the unit. 7

8 General Information Benefits of the SMi System Applying the SMi System is easy. The following flowchart outlines the basic steps of the process, which are typical for almost all air conditioning applications. This manual is structured with separate chapters focusing on each of the steps along with a separate chapter on each type of indoor unit. We have also included a chapter which outlines an example of an SMi application. Zoning Indoor unit selection Capacity correction Piping design Controls selection Wiring design As with all air conditioning applications, proper zoning is important. To maximise the benefits of heat recovery, indoor units connected to a common system should have opposing loading characteristics. Indoor units are selected based on the predicted heat load as well as the style and layout of the space to be air conditioned. Air distribution and sound level characteristics may also be factors for consideration. Indoor unit capacity will be adjusted based on the expected length and height of pipe runs and environmental conditions. The piping network for the indoor units will be based on the positioning of the Multi Controllers and building layout. The controls selection is dependent on the specification. Toshiba has a wide range of control systems available and has collaborated with customers on the development of unique systems to meet specific application requirements. Each of the indoor units will be powered by the outdoor unit. Control wiring requirements will be determined by the controls selection. 8

14 Four-Way Cassette Air Distribution Control Conditioned air can be distributed through 2, 3 or 4 sides of the unit to optimise the flow distribution in a room. Insulation blocks are included with the unit to close off the airflow to certain sides of the unit. The diagram 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 of the indoor unit. RAV-16/264UH-PE RAV-36/464UH-PE 3-way 3-way 3-way 3-way 3-way 2-way 3-way 2-way 2-way It is not possible to block the airflow from the longer sides of the unit (RAV 364/464 UH-PE). Insert insulation blocks, which are supplied as accessories, at each side where the airflow is not required as shown in the diagram opposite. Insulation Block 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. The combination of these two features gives the occupants total control over air movement within the room, via an easy-to-use remote controller. 14

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. The combination of these two features gives the occupants total control over air movement within the room via an easy-to-use remote controller. Fresh Air Facility An additional advantage of Toshiba s 4-way cassettes is that outdoor air, as well as conditioned air, can be introduced into the room. (Tempering to 15 C minimum is recommended.) Quiet Operation Noise levels have been reduced dramatically, thanks to the specially designed fan inlet that smoothes the airstream as it flows into an aerofoil fan and aerodynamic louvres. Easy to Install and Maintain The 4-way cassette can be concealed within most ceiling voids, with an ultra-thin 20 mm grille. This onepiece panel is easy to install. Its surface is easy to wipe clean, a feature it shares with the synchronised louvre blades. The long-life washable filter also minimises maintenance. 15

18 Four-Way Cassette Drain Piping Precautions Ensure 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 because deformation 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 indoor unit. The drain piping must be placed on a downward gradient (1/100 or greater) and there should be no upward 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: Upward curve m Support clamp X Insulator Downward curve Downward gradient 1/100 or greater Make this distance as long as possible approx. 100 mm Downward gradient 1/100 or greater Piping Material and Heat Insulator Heat Insulator* Hard PVC pipe** * Heat Insulator: Polyethylene foam (thickness 6 mm) ** Piping Material: Hard PVC pipe nominal diameter inside Ø20 mm Drain pan Drain hose Hard PVC adhesive Connection to the unit is via a 1 BSP male connection to ensure a waterproof seal, PTFE thread tape should be used. The maximum lift of the condensate pump from the drain outlet is 360 mm and the maximum overall lift from the underside of the ceiling to the centre of the drain piping is 600 mm. These values must not be exceeded, otherwise unit flooding will occur when the drain pump is switched off. 100 mm (max.) 360 mm (max.) 600 mm (max.) Cassette Ceiling 18

19 Four-Way Cassette Fresh Air Inlet These models have a cut out hole in the cabinet to enable outdoor air to enter the indoor unit at a maximum rate of 10% of selected air by volume. Before installing the unit, remove the cut out hole and insulation block and fit a spigot to connect the duct before hanging the unit. (Tempering incoming air to 15 C minimum is recommended.) Details of Cut-Out Hole 3 The cut out hole is a D shape half-cut hole on the side of the indoor unit, located on the side opposite the pipework.

The unit itself is totally concealed, usually within a ceiling void. Cool or warm air is then ducted into the room through diffusers discreetly positioned in the walls, floor or ceiling. These units can also be connected to an outdoor air supply. (Tempering to 15 C is recommended.) All-round Comfort Operated by an easy-to-use remote controller, Toshiba s ducted units provide perfect comfort throughout the room without leaving cool or hot spots. Design Flexibility Any style of air diffuser can be used, greatly increasing the scope for attractive interior design within the room. Moreover, should the room layout change, the diffuser s position can easily be moved with the very minimum of disruption. Greater design flexibility can be achieved with the option of return air to the underside or rear of the unit. The front spigot plate can be easily removed to allow for the connection of square ductwork. An optional remote sensor, 10 m in length which allows the return air sensor to be located within the room. 30

52 Capacity Correction Once the style and size of indoor unit has been selected, a check must be made to see if expected temperature conditions and estimated piping configuration has an affect on the preliminary choice. Reselection may be required after correcting. De-rating Indoor Units All indoor units have a standard capacity code setting that relates to the maximum amount of cooling available from each indoor unit. Adjusting the capacity code (called de-rating) can reduce the output of the indoor unit, but increases the sensible heat ratio (SHR). The capacity code is set using the rotary switches in the respective Multi-Controller and controls the maximum setting of the pulse-modulating valve (PMV). The available settings and respective rated total cooling duties (in kw) by unit are as follows. Indoor Default Capacity code settings available Unit Size Setting * * RAV-265KH-E and RAV-264NH-PE only Cooling Duty Correction for Temperature Cooling The 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 for the full range of temperatures. For convenience, we have included calculated duties at common design conditions (ambient and internal), with respective sensible duties at all settings (standard & de-rated).

59 Capacity Correction Cooling Duty Correction for Medium and Low Fan Speeds All cooling duties shown are at High fan speed. For medium and low fan speeds, correction is as follows: Fan speed Total cooling Sensible cooling Med Low Correction for Pipework - Cooling Cooling capacities are affected by pressure losses from pipework, so a correction factor must be considered and applied in the usual manner. We have supplied a table outlining factors with respect to lift and equivalent pipe length. Length (Equivalent) Lift - metres metres 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 temperature correction tables or graphs. Pipe runs do not significantly affect the sensible cooling duty, so a longer pipe run gives a reduction in latent cooling and consequently an increase in SHR. However, a reduction in sensible duty may eventually occur, by virtue of the fact that the sensible cooling duty can never exceed the total cooling duty. 59

60 Capacity Correction Cooling Duty 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 it has 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 unit it has 120% indoor/outdoor loading and consequently, the indoor units would not be able to produce 2.5 kw if they all asked for cooling at the same time (0% system diversity). Only 2.08 kw could be expected 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 the graph below. The graph can be used to determine the output of each indoor unit when the total system capacity 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 to 2.23 kw. Outdoor Unit Cooling Capacity Condenser Output (%) % (20) (21) (22) (23) (24) (25) (26) (27) (28) (29) (30) (31) (32) Loading (Capacity Code) 60

62 Correction for Pipework - Heating Capacity Correction Heating Duty Like cooling capacities, heating capacities will be affected by pressure losses from pipework, so a correction factor must be considered and applied in the usual manner. We have supplied a table outlining factors with respect to drop and equivalent pipe length. Length (Equivalent) Drop - metres metres Maximum allowed lift (outdoor unit below indoor unit) is 20 m. Only correction for length is required. Maximum allowed drop (indoor unit below outdoor unit) is 50 m. Correction for length and drop is required. These factors should be applied to the heating figures obtained from the temperature correction graphs. 62

This reduces the efficiency, by inhibiting the amount of heat transfer from the environment to the refrigerant. A graph is supplied to correct for any loss in duty associated with this effect. Capacity correction value by frosting to outdoor heat exchanger 1.0 Capacity correction value Outdoor temperature C 63

64 Capacity Correction 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 in ducting, which is in turn determined by ductwork length and design, affects the airflow. After a resistance has been calculated, the corresponding volumetric flow can be obtained from the fan curves included in the indoor unit section (chapter 5). The airflow variation ratio is given by the corrected flow due to resistance divided by the standard airflow of the unit. The capacity correction Air-flow value variation can then ration be of read indoor off the unit graph. and capacity correction (For concealed duct type only) Capacity correction value Air flow variation ratio (%) 64

65 Capacity Correction Outdoor Unit Selection After all applicable correction factors have been applied to select the correct indoor units; the number of outdoor 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) % 21 to %* 21 to %* * Note: As these loadings exceed the 100% threshold, checks must be made to ensure that the loading of all the indoor units is acceptable for the total requirements of all the areas served by the system as a whole, when assuming the appropriate amount of diversity. Refer to the previous section on Correction for 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 is sometimes applied. The ambient temperature is not constant during a 24-hour period, so invariably a system will never be required to run at full-load for 24 hours a day. Usage is another factor to consider when applying diversity: meeting/conference/interview rooms are rarely all used all day and places like canteens are only used during the lunch period. Obviously when these areas are being used, building occupancy is shifted from room to room, so metabolic and small power gains also change. It follows then that the greater the number of areas served by a particular system, the greater the chances of having some diversity. The potential for diversity and heat recovery is also increased when there is a large geographical spread of areas being served by a system. 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% 11 Please note that diversity is difficult to predict and is not an exact science, but can be estimated using heat gain/loss calculation packages. Generally speaking 35% diversity (providing 65% of the maximum cooling/heating requirement) is considered to be the upper limit of diversity to assume in comfort cooling situations. 65

73 Multi Controller Installation The three pipes from the outdoor unit are connected to the Multi Controller which then controls the flow of the refrigerant to each of the indoor units. It also acts as a wiring centre for the indoor units, making the provision of a separate power supply unnecessary. The Multi Controllers have three (RBM-Y1034-PE) or four ways ((RBM-Y1044F-PE). Any outlets that are not used can be capped or valved off. Whilst all of the suction pipework within the Multi Controller is insulated to prevent condensation forming, when any unit is cooling, as a precaution a heater element is fitted to the base of the Multi Controller to evaporate any moisture that may collect in the base. This makes the provision of a separate condensate drain unnecessary. As standard, a maximum of two Multi Controllers can be connected to the outdoor unit, however by using the dual interface (RBC-DIF1-PE) this can be increased to a maximum of four. Wiring from two Multi Controllers 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 a false 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. 2 slots for hanging bolts (12 x 52) Electric parts box 2 notches for hanging bolts (12 x 21) 3-pipe: RBM-Y1034F/Y1044F-PE Connection (brazing) Liquid side ø Refrigerant pipe connection (brazing) Liquid side ø 12.7 Wiring knockouts 6 x ø 20 Note: Please instal this way up.

It may be that site requirements will determine alternative arrangements for a given number of indoor units. For example, if there are four indoor units split across two floors, it may be more convenient for piping 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 of a Multi-Controller. These two units would act as master and slave, sharing control inputs and would therefore both have the same mode, set point, fan speed etc. The capacity code is set using the rotary switches in the respective Multi-Controller as follows: Indoor units Capacity code settings available x RAV-10 No No No No No No No No Yes Yes Yes 2 x RAV-13 No No No No No No Yes Yes Yes No No 2 x RAV-16 No No No No Yes Yes Yes No No No No 2 x RAV-26* No No Yes Yes Yes Yes Yes No No No No 2 x RAV-26 Yes Yes Yes Yes Yes No No No No No No * RAV-265KH & RAV-265NH only 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 indoor units 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. 76

80 Refrigerant Piping Design Insulation All piping will need to be thermally insulated with Class O or equivalent, to local regulations and suitable for the ambient temperature experienced. Insulation shall be as follows: Within buildings: Pipe diameter Insulation wall thickness 1/4 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 prevent excessive heat loss through the insulation, resulting in poor heating performance. Where insulated refrigerant pipes penetrate dividing fire-resistant walls and/or ceilings the pipework shall pass through sleeves and the space around the pipes shall be sealed with an approved material to prevent 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 main piping (P1). Additional refrigerant will be required as follows - the weight required determined by the length of liquid pipes, in accordance with the table below.

81 Controls Introduction The control system that the SMi system is based around, is a serial link that combines communication to the indoor and outdoor units. In the case of SMi system, the network controlling device is connected to the indoor units although existing SMi products can be combined onto the same platform (except for RAV cooling only split systems). The controls may be classified as local or network, and any indoor unit may be controlled by either, or a combination 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 allows connection 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 SMi outdoor unit to the network. System Control The system control data is distributed with the power cables from the outdoor unit used in the serial cable, not via a separate network. RBC-SR1 or RBC-SR2 Network control 14 81

82 Controls Local Controls End users can make adjustments to indoor units either individually or in groups of up to 16. Infrared and wired options may be combined with networked controls, to provide local setting, subject to three levels of authority, set from the network. Individual or Group Control All local controls can provide operating instructions to either individual indoor units or groups of up to 16 indoor units. Wired controllers are connected to terminals A-B-C of the appropriate indoor units. RBC-SR1 or RBC-SR2 Up to 16 indoor units When group controlling, terminals B-C are connected throughout the group. All indoor units are provided with the same instructions, however they operate independently to achieve the common set point. Indoor units within a group are addressed by switch 1 (16 position, rotary switch). Jumper CN12 will be removed from slave units. Connected by 3 core cable > 1.0 mm 2. Grouped indoor units, linked by further 2 core cable > 1.0 mm 2. Group wiring can be up to 500 m in length. 82
