摘要: A refrigerant circuit (20) includes a low stage compressor (101, 102, 121, 122), a high stage compressor (41, 42, 43), an outdoor heat exchanger (44) and a utilization side heat exchanger (83, 93). During a defrosting operation of the refrigeration system (10), the high stage compressor (41, 42, 43) is driven. Refrigerant discharged from the high stage compressor (41, 42, 43) is pumped into the utilization side heat exchanger (83, 93) to heat frost on it from its inside. Thereafter, the refrigerant evaporates in the outdoor heat exchanger (44), is then compressed by the high stage compressor (41, 42, 43) and is sent again to the utilization side heat exchanger (83, 93).

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).
