摘要： Provided is a refrigeration apparatus that uses R32 for the refrigerant, and that is capable of injection in order to suppress the discharge temperature even in the case in which operating efficiency deteriorates by intermediate injection. An air conditioning apparatus (10) that uses R32 refrigerant is provided with a compressor (20), an indoor heat exchanger (50), an outdoor expansion valve (41), an outdoor heat exchanger (30), an intermediate injection channel (65), a suction injection channel (67) and injection switching valves (66, 68). The intermediate injection channel (65) causes a part of the refrigerant flowing in a main refrigerant channel (11a) to merge with intermediate-pressure refrigerant of the compressor (20). The suction injection channel (67) guides a part of the refrigerant in the main refrigerant channel (11a) to a suction passage (27).

摘要： Provided is a refrigeration apparatus that minimizes increase in the size of the heat exchanger for injection while maintaining the function of reducing the discharge temperature of the compressor. An air conditioning apparatus (10) that uses R32 for the refrigerant, is provided with a compressor (20), an indoor heat exchanger (50), an outdoor expansion valve (41), an outdoor heat exchanger (30), a branch flow pipe (62), and an electric injection valve (63) and a heat exchanger (64) as well as a high-pressure receiver (80) and the like. The heat exchanger (64) exchanges heat between refrigerant that flows in the main refrigerant passage (11a) and refrigerant that passes through the electric valve (63) of the branch flow pipe (62). A first injection channel (65) guides refrigerant that flows through the branch flow pipe (62) and exits the heat exchanger (64) of the compressor (20). A second injection channel (82) guides the gas component of refrigerant of the high-pressure receiver (80) to the compressor (20).
