Abstract: High efficiency of a compressor that compresses a mixed refrigerant containing at least 1,2-difluoroethylene is achieved. A compressor (100) includes a motor (70) that has a rotor (71) including permanent magnets (712) and thus is suitable for a variable capacity compressor in which the number of rotations of the motor can be changed. In this case, it is possible to change the number of rotations of the motor in accordance with an air conditioning load in an air conditioner (1) that uses a mixed refrigerant containing at least 1,2-difluoroechylene. It is thus possible to enable high efficiency of the compressor (100).

Abstract: A refrigeration cycle apparatus that can improve operation efficiency when a refrigerant that contains at least 1,2-difluoroethylene is used is provided. An air conditioning apparatus 1 includes a compressor (21), an outdoor heat exchanger (23), an outdoor expansion valve (24), an indoor heat exchanger (31), and a suction injection pipe (40), and uses a refrigerant that contains at least 1,2-difluoroethylene. The suction injection pipe (40) allows a part of a refrigerant that flows toward the indoor heat exchanger (31) from the outdoor heat exchanger (23) to merge with a low-pressure refrigerant that is sucked into the compressor (21).
