Abstract

A refrigerant circuit (20) has low stage side compressors (101, 102, 121, 122), high stage side compressors (41, 42, 43), an outdoor heat exchanger (44), and utilization side heat exchangers (83, 93). In defrosting operation of a refrigeration apparatus (10), the high stage side compressors (41, 42, 43) are operated. Refrigerant discharged from the high stage side compressors (41, 42, 43) is introduced into the utilization side heat exchangers (83, 93) and heats frost from the inside. After that the refrigerant is evaporated at the outdoor heat exchanger (44), compressed by the high stage side compressors (41, 42, 43), and then sent again to the utilization side heat exchangers (83, 93).
