REFRIGERATING AND FREEZING COMBINE AIR CONDITIONING SYSTEM

摘要

PURPOSE: A composite air-conditioning system is provided to enable air-conditioning and refrigerating/freezing to be efficiently performed since condensation heat is collected between an air conditioning unit and a refrigerating unit and between the refrigerating unit and a freezing unit. CONSTITUTION: A composite air-conditioning system comprises an air conditioning unit(100), a refrigerating unit(200), a heat exchange unit(300) and a switching member. Air-conditioning refrigerant is circulated through the air conditioning unit. The air conditioning unit comprises a first compressor(110), an outdoor heat exchanger(120) and an indoor heat exchanger(130). Refrigerating refrigerant is circulated through the refrigerating unit. The refrigerating unit comprises a second compressor(210), a refrigerating condenser and a refrigerating evaporator(230). The heat exchange unit heat-exchanges the refrigerant of the air conditioning unit and the refrigerating unit. The switching member passes compressed refrigerant through the refrigerating condenser and the heat exchange unit or passes the compressed refrigerant through only the heat exchange unit.
