Abstract:
A refrigerant circuit (15) is provided with a low-pressure stage oil separator (26) for separating refrigerating machine oil out of refrigerant discharged from a low-pressure stage compressor (21) and returning it to the suction side of the low-pressure stage compressor (21), and a high-pressure stage oil separator (36) for separating refrigerating machine oil out of refrigerant discharged from a high-pressure stage compressor (31) and returning it to the suction side of the high-pressure stage compressor (31). The efficiency of oil separation of the low-pressure stage oil separator (26) is set lower than that of the high-pressure stage oil separator (36).
