Abstract: A compressor uses a refrigerant containing R1123 (1,1,2-trifluoroethylene) as a working fluid, and uses a polyvinyl ether oil as a compressor lubricating oil. In addition, a fixed scroll and a revolving scroll each having a spiral lap rising from an end plate, and a compression chamber which is formed by meshing the fixed scroll and the revolving scroll, are provided. In addition, a discharge hole which is provided at a center position of the end plate of the fixed scroll, and is open to a discharge chamber, a bypass hole which is provided in the end plate of the fixed scroll, and communicates with the compression chamber and the discharge chamber at a timing different from a timing at which the compression chamber communicates with the discharge hole, and a check valve which is provided in the bypass hole, and allows a flow from the compression chamber side to the discharge chamber side.

Abstract: A refrigeration cycle device includes a refrigeration cycle formed by connecting a compressor, a condenser, an expansion valve and an evaporator 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 the expansion valve is controlled such that the refrigerant has two phases at a suction portion of the compressor. With such a configuration, it is possible to provide highly reliable refrigeration cycle device by suppressing occurrence of a disproportionation reaction of R1123.
