A refrigerant outlet of the first evaporator is connected to a suction inlet of a compressor, which is connected to a radiator. A branched passage branches a flow of the refrigerant at a corresponding branching point located between the radiator and the ejector. The branched passage conducts the branched flow of the refrigerant to a suction inlet of the ejector. A flow rate control valve is arranged in the branched passage between a radiator and an ejector on a downstream side of the radiator to depressurize refrigerant outputted from the radiator. A second evaporator is arranged in the first branched passage.
