(Tel) 01372 220240) The outdoor unit shall be factory assembled, pre-wired, works tested, supplied with a refrigerant pre-charge suitable for 15 m (301.401), 20 m (561/801) & 30m (1101-1401) of main piping and complete with fully sealed pipe work connections. It shall not be necessary to include oil traps, sight glasses, or external driers. The access panel shall be easily removable for servicing. The condensing unit shall be fitted with its own electrical compartment with all necessary electrical and control components. The casing shall be manufactured from Galvatite steel plate with a Silky Shade (Munsell 1Y8.5-0.5) electrostatic spray finish protected to IP X4 and shall contain the following components: Inverter Driven Twin Rotary Compressor The compressor shall be of the twin rotary type and driven by a High-Speed Calculation Vector Control Inverter, creating seamless capacity control to match the connected indoor unit(s) cooling or heating demand. Fixed speed compressors of any type are not to be used. The compressor shall be factory mounted on springs and shock-absorbing rubber to minimise vibration. Heat Exchanger The heat exchanger shall be factory constructed of rifled copper tubing, mechanically bonded to aluminium fins. The aluminium fin material shall be coated with a double synthetic hydrophilic coating to prevent corrosion and to assist condensate dispersal. The condensing coil shall have a large surface area to minimize noise and maximise heat transfer. Fan and Motor Each outdoor unit is to be fitted with no more than a single fan. The fan shall be a three-blade, flash-wing, low noise type and shall be both dynamically and statically balanced to produce minimum noise and vibration. The fan shall be directly coupled and driven by a drip proof, permanently lubricated variable speed high-efficiency inverter controlled motor. The outdoor fan speed shall be matched automatically to the energy demands of the heat exchanger. The fan must be able to overcome an external static resistance of 15Pa. Suction Line Accumulator
Digital Inverter Standard Specification R32 The cylindrical accumulator shall be fabricated from press formed mild steel plates. The accumulator shall have sufficient capacity to prevent any liquid refrigerant from flowing back into the compressor section. Additional Features & Safety Devices: 4-way reversing valve, solenoid valves, pulse-modulating valve, strainer, dryer, service valves with 5/16 gauge ports, thermal protection for compressor, recycling guard timer, over-current protection, compressor suction and discharge temperature sensors, terminals, internal wiring and controls. A pulse-modulating valve will provide capacity control by maintaining suction temperatures of between 1 and 5 K higher than the evaporator inlet temperature additionally, the indoor heat exchanger will be limited to temperatures of no less than 2ºC when cooling. The outdoor unit will automatically defrost in the heating cycle. Indoor Units Each indoor unit shall be from Toshiba s Digital Inverter range of units and must operate on 220-240 Volt, single-phase, 50 Hz supply taken from the outdoor unit. It must be fully compatible with all TCC-Link network systems, including a self-diagnostic TCC-Link remote controller or TCC-Link central controller with LCD to set mode, room temperature, timer, louvre (as applicable), fan speed and on/off functions. In the event of a fault, an alphanumeric malfunction code will be displayed. An auxiliary 12V DC output is to be available using the CN32 connection. This can be used to operate a ventilation fan via a relay (RBC-SMFI) when the indoor unit is operated. The heat exchanger shall be factory constructed of rifled copper tubing, mechanically bonded to aluminium fins. The aluminium fin material shall be coated with a hydrophilic coating to prevent corrosion and to assist condensate dispersal. The coil shall have a large surface area to minimize noise and maximise heat transfer. A fully insulated condensate drip tray must be fitted, which spans the full width of the coil connections and complete with a drain connection point. All indoor units are provided with a return air temperature sensor. The heat exchanger will be protected against excessive temperatures both low and high. Cold draughts will be avoided when heating by automatically stopping the indoor fan motor when the heat exchanger is too cold. Excess heat is to be dissipated by operating the indoor fan motor for a further 30 seconds after unit shutdown. The evaporator fan shall be of the multi-blade type, performance matched to the coil. The fan shall be statically and dynamically balanced to ensure low noise and vibration free operation and be driven by a permanently lubricated configurable DC motor with speed control and stall protection and fitted with maintenance free sealed-for-life sleeve bearings. 4-Way Cassette RAV-RM561UTP-E RAV-RM801UTP-E RAV-RM1101UTP-E
