  • Patent number: 11391499
    Abstract: In a heat pump cycle device, a flow passage switching portion includes a flow passage switching valve body configured to open and close a cooling side flow passage. A refrigerant circulation circuit includes a low-pressure flow passage through which a low-pressure refrigerant decompressed by a first decompressor flows toward a compressor in a heating mode, and a pre-evaporator flow passage provided between the flow passage switching valve body and a refrigerant inlet of an evaporator. The flow passage switching portion causes a pre-evaporator flow passage to communicate with the low-pressure flow passage while bypassing the evaporator when a refrigerant pressure in the low-pressure flow passage is lower than a refrigerant pressure in the pre-evaporator flow passage, in the heating mode.
