PROBLEM TO BE SOLVED: To prevent a defrosting operation from stopping an air conditioning operation in all the evaporators in an ejector cycle comprising a plurality of evaporators capable of exerting a freezing capacity. SOLUTION: First and second four-way valves 14 and 19 provide switching between a refrigeration evaporator defrosting mode in which a refrigerant discharged from a compressor 11 flows through a condenser 12, a refrigeration heat exchanger 15, a nozzle 20a, a gas/liquid separator 21, a freezing heat exchanger 16 and a gas phase inlet 20c in the order named, and a freezing evaporator defrosting mode in which the refrigerant discharged from the compressor 11 flows through the condenser 12, the freezing evaporator 16, the nozzle 20a, the gas/liquid separator 21, the refrigeration evaporator 15 and the gas phase refrigerant inlet 20c in the order named.
