Page 9: Technical Characteristics
4 TECHNICAL CHARACTERISTICS The PACK DUE water chillers and heat pumps series are designed for applications in residential and commercial areas, These units are extremely versatile and can operate in heat pump mode with the ability of producing hot water at a temperature of 55°C for environmental heating and sanitary applications. The INVERTER compressor with brushless DC motor technology, matched with electronic expansion valve, pump and variable speed blower are generally used for optimizing the power consumption and efficient operation of the refrigerating components. 4.1 FRAME All PACK DUE units are made up of hot‐galvanised thick sheet metal, painted with polyurethane powder enamels at 180°C to ensure the best resistance against atmospheric agents. The frame is self‐supporting with removable panels. All screws and rivets for outdoor installations are in stainless steel. 4.2 REFRIGERANT CIRCUIT The refrigerant gas used in these units is R410A. The refrigerant circuit has been manufactured by means of international primary brands components and according to the UNI EN 13134 rule concerning welding procedures. The refrigerant circuit includes: Safety device on the gas side, 4 way reverse cycle valve, electronic expansion valve, liquid receiver, valves for maintenance and control, pressure safety device according to PED regulation (high pressure switch), pressure transducers to accurately adjust the evaporating and condensing pressures, filters for throttling valve to avoid its clogging. 4.3 COMPRESSORS The used DC inverter compressors are a rotary hermetic single‐phase type (only for the models PACK DUE 7 and PACK DUE 9) and twin rotary single‐phase (for the model PACK DUE 12), and scroll 3‐phases type (for PACK DUE 16) designed to be ... -
