ABSTRACT:
In a refrigerating apparatus comprising a rotary compressor, a pressure-controlled valve is inserted in a path between a condenser and an evaporator and a reverse flow check valve is inserted between the evaporator and a suction line connected to the input port of the rotary compressor, thereby to eliminate undesirable heat load caused by undesirable flow-in of the refrigerant gas into the evaporator after the rotary compressor stops.
