摘要： An object of the present invention is to continue operation as it is without inducing any degradation of performance of a compressor even if one of compressors is broken down in a refrigeration apparatus which can freely cool or warm the inside of a room, cool a refrigerating show case and cool a freezing show case. A refrigeration apparatus (1) comprises a non-inverter compressor (2A), a first inverter compressor (2B) and a second inverter compressor (2C). If the first inverter compressor (2B) is broken down during a cooling/freezing operation in which a cooling operation is performed by an inside heat exchanger (41), a refrigerating heat exchanger (45) and a freezing heat exchanger (51), the operation is continued by opening a solenoid valve (7a) disposed on a first sub pipe (23).

摘要： In a refrigerant circuit (20), an air conditioning unit (12), a cold-storage showcase (13), and a freeze-storage showcase (14) are connected in parallel to an outdoor unit (11). When placing an indoor heat exchanger (71) of the air conditioning unit (12) in the thermo-off state, a degree-of-opening control means (101) provides control so that an indoor expansion valve (72) is placed in the fully closed state. Thereafter, the degree-of-opening control means (101) detects the accumulated amount of refrigerant within the indoor heat exchanger (71) and then adjusts the degree of opening of the indoor expansion valve (72) depending on the refrigerant amount detected.
