A privately owned company, temperzone Holdings td, is the parent company of temperzone ltd (est.956) in Auckland and temperzone Australia pty ltd in Sydney. The wide range of temperzone products are manufactured in Auckland for markets in Australasia and Asia. This range includes air distribution items and fans for ew Zealand. The Sydney headquarters acts as both a distribution centre and manufacturer of customised and larger standard air conditioning units specifically for Australia. temperzone s Asia Regional Head Office is located in Singapore. The combined group operations employ over 5 staff. Temperzone s Fan Coil History Temperzone have been manufacturing chilled water fan coil units for more than 5 years. The original RCMC units were superseded in the mid 98 s with a new breed of RCMC which were then superseded in the late 99 s with the IMD range. Prior to the development of temperzone s C motor fancoils, units had all been manufactured with fixed single speed or multi-speed PSC motors. Any changes in the cooling or heating performance had been solely on the basis of varying the water flow by way of a -way or -way water regulating/ modulating valve. With the indoor fan running on a constant speed. This left considerable room for improvement in designing higher efficiency models. It is time now to take a step forward with the new IMD Y version with high efficiency C (lectronically Commutated) motors. C motors allow for the air flow to be controlled over a wider range either by the multiple speeds that are available or by the use of a V dc variable signal. Speeds as high as 5 rpm and as low as 5 rpm are available by dip switch selection in multi-speed or variable voltage signal. By utilising the C motor technology it is no longer necessary to have the S, M and H models, one model size suits all with the required speed range selected by dip switches Key Features nergy fficient C Motor Significant nergy Savings Independent Fan Operation On-site Adjustable Fan Air Volume Controller Remote Fan Air Volume Adjustment Capability from BMS. RA Fan coil units are an integral part of an overall air conditioning system where the energy transfer medium (i.e. chilled or hot water) is circulated by a central plant facility. temperzone offers an extensive range of ducted fan coil units. A variety of options and accessories are available to meet most air conditioning requirements. ow operating cost, energy efficient fan motors are used in all units. asy installation and maintenance add to the cost effectiveness of temperzone IMD Series fan coil units. All IMD fan coil units can be handed left or right. Unless otherwise ordered units will be supplied right handed which is the standard handing, i.e. when facing the discharge side of the unit, the water and electrical connections are on the right hand side. TYPICA APPICATIOS Office Buildings The low overall height of 6 mm makes them ideally suited to office building applications where false ceiling space is at a premium. Hotels IMD units are extremely well suited for individual room control. A standard above ceiling installed unit with speed control (available option) is normally used for this type of application. Airport Terminal Buildings temperzone fan coil units are gaining worldwide popularity in airport terminals. These complexes generally consist of a number of areas with very diverse occupancy and capacity requirements. Hospitals The majority of hospital rooms must have a separate and independent air conditioning system. This is to avoid bacterial cross contamination. temperzone fan coil units have been used successfully in these applications. STADARD FATURS Drain Tray The drain tray is plastic and is removable for ease of cleaning and can be adjusted to slope when the unit is installed level. Motors High efficiency electronically commutated (C) motors are fitted as standard on all units. Motors can be operated on three speeds (site changable) or -% capacity using a -V dc signal supplied by a BMS or sophisticated controller. The motors are resiliently mounted, self aligning and oiled for life. Fans Quiet low line, centrifugal type, double width, statically and dynamically balanced, multi-bladed impellers are used. The position and shape of the fan blades and housing has been developed after extensive testing to achieve minimum noise levels while maintaining a smooth pressure vs air flow curve. Coils Coils are manufactured in rifled copper tubing. All coils are thoroughly tested to kpa. Coil rows are staggered for maximum heat exchange. Three different coil configurations are available refer table on page 5. The coil fins are manufactured as a continuous plate, die formed from epoxy aluminium with a smooth corrugated surface, specially designed to overcome and prevent lint build up. The coil fins are mechanically bonded to the copper tubing which results in a rigid assembly and provides a permanent metallic contact between fins and tube for maximum heat transfer. Casing The casing is manufactured from high quality galvanised steel and internally insulated. Insulation Closed cell foam insulation has been used in the cabinet to ensure no particles are introduced into the air stream. The insulation is foil faced and meets the fire test standards AS 5. (989) and BS 76 parts 6 and 7. Open cell foam is used in the return air section for noise attenuation. CTRICA BOX Wiring from the motors terminate in a terminal block in a sheetmetal enclosed electrical box. The box is supplied on the same side as the water connections, but can be changed on site to the opposite side. STADARD OPTIOS.

3 TCHOOY Specification VAV For the last years virtually all fan coil units have operated with a constant fan speed and therefore constant air volume (CAV). Temperature changes in these units were achieved by the water valve, i.e. varying the water volume. With this design, energy was wasted due to fans constantly running at full speed, regardless of the requirement of the thermal zone served. With temperzone s new range of VAV fan coil units, varying air volume results in greater efficiency. Controls The new C motor version IMD units allow for several methods of control allowing great flexibility to meet the demands of modern buildings expectations. The fan speed could be adjusted for instance as the first step of capacity control before adjusting water flow. Three Speed Selection The fans can be controlled just like their predecessors using three speed selection, high, medium and low. This option is selectable by dip switch and then by using further dip switch settings to select from the available speed ranges that are most suitable for the application. Potentiometer The fans could also be controlled by the fitting of a potentiometer to preset the required speed. This will be particularly useful during onsite commissioning to be able to adjust to obtain the desired air flow. Indoor Fan Speed The fan can be switched O by selecting High, Medium or ow fan speed on the terminal block, or via BMS. The fan speed can be controlled in two ways: Stepped or Continuously Variable. Dip switches to 5 and 7 on the Analogue evel Controller (AC) determine the minimum and maximum fan speeds. The same Minimum rpm and Maximum rpm settings apply to both the Stepped and Continuously Variable control methods. There are two fan speed ranges available using dip switch 7: - ow, which is the default for low profile IMD units & - High, which is the default for in higher air flow IMD units. The default settings for max. fan speed and fan speed range are highlighted on the Wiring Schematic.. Stepped ( Speed) If using a -speed selection switch, the medium speed will always be half way between the maximum (High) and minimum (ow) speeds as selected using the DIP switches to 5.. Continuously Variable (-V Control) If using a variable V dc signal (from a BMS or sophisticated controller) the fans will not operate until a signal above. is received and will then start at the minimum voltage/speed set using DIP switches to 5. A voltage below. DC applied across the V and the -V input terminals will activate fan run on and after this the fan will stop. A control voltage of V will cause the fan to run at the Min. rpm speed. A V DC signal will run the fan at the Max. rpm speed. Control voltages between these two limits (V V) can be used to achieve any desired speed between Min. and Max. rpm in a linear relationship so gives you Med. (halfway between Min. and Max ). ote: Only one control method must be connected at any one time; either Stepped Speed control or Continuously Variable -V dc, not both. The fan will run on at ow speed when there is no input signal for either or seconds, dependant on the DIP switch 6 setting, before stopping. If electric heat is fitted, ensure that DIP switch 6 is set for seconds. BMS Many modern buildings these days have Building Management Sytems (BMS) and it is most desirable to control the fan speed variably to meet the building s load demands. The unit can accept a - signal from the BMS or other sophisticated controller. This option is again selectable by dip switch and likewise so is the allowable speed range. The BMS can be programmed to achieve various beneficial functions such as; maintaining high air flow when on heating first thing in the morning to avoid stratification within the space, reducing the air flow down to say 5 to 6% as a capacity control method prior to adjustment of the water flow.
