A refrigerant that has flowed out of a liquid ejector radiates heat in a radiator, and a liquid-phase refrigerant that has radiated heat in the radiator flows into an ejection refrigerant passage of the liquid ejector. A discharged refrigerant of a compressor that suctions the refrigerant that has flowed out of a low-pressure evaporator flows into an inflow refrigerant passage of the liquid ejector. An ejector adopted as the liquid ejector is one in which an ejection refrigerant is ejected from the ejection refrigerant passage to a gas-liquid mixing portion, and the ejection refrigerant is ejected on an outer circumferential side of the inflow refrigerant flowing from the inflow refrigerant passage into the gas-liquid mixing portion.
