REFRIGERANT CIRCUIT

WIPO Patent Application WO/2002/101304

A1

A refrigerant circuit capable of performing a refrigerating cycle by compressing refrigerant to a critical pressure or higher by a compressor (15), comprising the compressor (15), a water heat exchanger (16), a receiver (18), an expansion valve (19), and an evaporator (20), wherein a cooling part (17) for cooling the refrigerant flowing out of the water heat exchanger (16) is installed on the upstream side of the receiver (18), a part of the evaporator (20) is allowed to function as an air heat exchanger so as to function as the cooling part (17), and the cooling part (17) exchanges heat with the refrigerant on the outlet side of the evaporator (20).
