6 2 Specification text Unit construction Compact, modular and weatherproof design air-cooled chiller for outdoor installation IP24 - manufactured according to the lso900 quality standard. The ready-to-connect range has been designed for both air conditioning and process cooling applications and meets PED conformity. The use of state-of-the-art technologies and high quality materials ensures efficiency, reliability and an extended service life. Each DAlKIN chiller is subjected to many hours of test runs in the factory allowing for standard requirements. 2 Casing / Colour Powder coated, galvanised steel plate. Fully factory assembled on a base frame. Colour ivory white (± RAL 7044) / Munsell code 5Y7.5/ Number of cooling circuits Size 0-40 single circuit, double circuit. Each refrigerant circuit has its own fully independent design thereby guaranteeing a high level of system reliability. Compressor New, semi-hermetically sealed DAIKIN stepless single screw compressor developed and optimised for refrigerant R- 407C. The single screw principle of a main screw meshing with 2 satellite rotors eliminates radial and axial bearing loads due to balanced pressures under all operating conditions. Bearings are designed for over 00,000 operating hours or equivalent to the full service life of the compressor. The main screw is directly driven by a suction cooled 2 pole, Phase induction motor and is cooled by refrigerant injection. Satellite rotors are made from a hard wearing polymer material eliminating metal to metal contact allowing closer tolerances and increasing running life. At 2880rpm and 2 compressions per rotation the 4,560 compressions per minute prevents pulsating compression gas and resembles a smooth discharge flow, thereby reducing vibration and noise emission. In addition the twin wall structure of the compressor casing together with the integrated oil separator offers additional attenuation. Stepless control of the sliding vane determines the volumetric ratio of the compressor in function of the chilled water temperature. Control is infinitely variable from 0 to 00%. Additional features include: integrated oil separator incorporating muffler effect, oil lubrication by pressure difference (no oil pump required), oil sump heating, oil inspection glass, non-return valve, hot gas shut-off valve, service valves, suction gas filter, Klixon embedded in the motor winding, star or delta start up. The high efficiency design is optimised for the refrigerant and system and ensures the highest COP values and operational reliability. System and service costs are minimised. Condenser High-performance design Cu/Alu heat exchanger - arranged in a V- shape. Consisting of internally drawn helical Cu pipe (Hi -X) guaranteeing excellent heat transmission and optimal oil transport. Provided with a builtin subcooler to further improve performance. By increasing the heat transmission surface using continuous laminated honeycomb slotted flaps, a very low sound level is attained still with compact dimensions. By chromatising the whole of the heat exchanger, it is permanently protected against corrosion thereby extending the range of applications of this device. Fans Inverter driven, low-noise axial fans with outlet protective grating. Statically and dynamically balanced drive motor design with maintenance-free bearings for outdoor installation. Motor safety class IP54. In heat recovery mode the inverter fans control the condensing temperature between 9 to 22 Bar for optimum heat recovery. In cooling mode the inverter fans control the condensing temperature at Bar for optimum efficiency. Applied Systems Chillers 7

7 2 Specification text 2 Evaporator R-407C optimised DX counter flow plate heat exchanger made of stainless steel, plates brazed gastight with copper, for water and glycol mixtures. A special refrigerant distribution system (Equalancer System M) has been incorporated into each duct plate for optimal capacity of the complete heat transmission surface As well as an additional increase in efficiency of approx. 6%, this is also responsible for stable control behaviour in the heat exchanger. The plate heat exchanger is standard equipped with heater tape to prevent freeze-up and is heat-insulated (PVC nitril foam) to ensure it is diffusion-proof to prevent any heat loss. The water pressure may not exceed the maximum permissible operating pressure of 0 bar! Heat Recovery Condenser R-407C optomised DX counter flow plate heat exchanger made of stainless steel (AISI6) plates, brazed gas tight with copper, for water and glycol mixtures. The plate heat exchanger is standard equipped with heater tape to prevent freeze-up and is heat insulated (PVC nitril foam) to ensure it is diffusion-proof to prevent any heat loss. The water pressure may not exceed the maximum permissible operating pressure of 0 bar! Depending on the temperature requirement for the hot water production this exchanger will act either as a desuperheater for partial heat recovery (0%) or as a condenser for full heat recovery (85%). Piping Consisting of Cu pipe with all the necessary cooling fittings such as: Service valves, filter-drier, inspection glass with moisture indicator, solenoid valve and TEV with external pressure equalisation. The plate heat exchanger is cased with galvanised steel. Safety and control devices Permanent temperature and pressure monitoring of the refrigerant circuits by the PCO² digital controller using high- and low-pressure sensors. Each refrigerant circuit is fitted with the following safety devices: Pressure limitation control / safety pressure limitation control, drain valve, lowpressure switch, hot gas temperature monitoring, heat cut-out for compressor and fan motors, overload relay, frost protection and evaporator companion heating. Each refrigerant circuit is fitted with the following control devices: Electronic temperature monitoring, phase-sequence relay, high- and low-pressure PCO² digital controller display, timing safety device and switch frequency limiter. Switching and control device In addition to the fully automated PCO² digital controller, the control cabinet manufactured by SIEMENS in accordance with the valid EN directives (CE) fulfils safety class IP 54 and contains all the required switching and control components such as: load, auxiliary and control cut-outs, transformers, control fuses, relay and auxiliary relay, sensors, control PCBs and PCO 2 digital controller. The electronics have an automatic restart after power failure and provide the following digital inputs and outputs hard-wired to terminals for incorporating the GLT: 8 Applied Systems Chillers
