ABSTRACT:
Disclosed is a refrigerant circuit which comprises a compressor (15), a water heat exchanger (16), a receiver (18), an expansion valve (19), and an evaporator (20). In the refrigerant circuit, a refrigerating cycle is carried out by compressing refrigerant to above a critical pressure in the compressor (15). A cooling section (17) for cooling refrigerant flowing out of the water heat exchanger (16) is provided on the upstream side of the receiver (18). A part of the evaporator (20) functions as an air heat exchanger which operates as the cooling section (17). The cooling section (17) exchanges heat with refrigerant on the outlet side of the evaporator (20).
