<P>PROBLEM TO BE SOLVED: To stably operate an ejector type refrigeration cycle even with a change in the flow rate of a driving flow that passes a nozzle of an ejector. Ž<P>SOLUTION: A refrigerant outlet of a suction side evaporator 16 is connected to the refrigerant suction port 13b side of the ejector 13, and a second compression mechanism 21a is provided between the suction side evaporator and the refrigerant suction port 13b of the ejector 13. Consequently, even in such operating conditions that the suction capacity of the ejector 13 is degraded accompanied by a fall in the flow rate of the driving flow of the ejector, the suction capacity of the ejector 13 can be assisted by the second compression mechanism 21a. The ejector type refrigeration cycle can thereby be stably operated while exhibiting high COP (coefficient of performance) even with the change in the flow rate of the driving flow.
