Abstract: An ejector refrigeration cycle has a compressor, a radiator, an ejector, a swirl flow generator, an evaporator, and an oil separator. The compressor compresses refrigerant, mixed with refrigerant oil compatible with a liquid-phase refrigerant, and discharges the high-pressure refrigerant. The ejector has a nozzle and a body having a refrigerant suction port and a pressure increasing part. The swirl flow generator is configured to cause a decompression boiling in the refrigerant by causing the refrigerant to swirl about a center axis of the nozzle. The oil separator separates the refrigerant oil from the high-pressure refrigerant compressed by the compressor and guides the refrigerant oil to flow to a suction side of the compressor. The oil separator decreases a concentration of the refrigerant oil in the refrigerant, which is to flow into the swirl flow generator, so as to promote the decompression boiling of the refrigerant in the swirl flow generator.
