REFRIGERATION CYCLE DEVICE

A refrigeration cycle device includes a refrigeration cycle formed by connecting compressor (2), condenser (3), expansion valve (4) and evaporator (5) to each other. As a refrigerant in the refrigeration cycle, a working fluid containing 1,1,2-trifluoroethylene (R1123) and difluoromethane (R32) is u...

Beschreibung
Zusammenfassung:	A refrigeration cycle device includes a refrigeration cycle formed by connecting compressor (2), condenser (3), expansion valve (4) and evaporator (5) to each other. As a refrigerant in the refrigeration cycle, a working fluid containing 1,1,2-trifluoroethylene (R1123) and difluoromethane (R32) is used. A degree of opening of expansion valve (4) is controlled such that the refrigerant has two phases at a suction portion of compressor (2). With such a configuration, it is possible to provide highly reliable refrigeration cycle device (1) by suppressing occurrence of a disproportionation reaction of R1123.
