A refrigerant cycle 20 provides a heat pump cycle apparatus. An outdoor heat exchanger 22 is used as a condenser in a cooling operation and a second dehumidifying and heating operation. The outdoor heat exchanger 22 is used as an evaporator in a heating operation and a first dehumidifying and heating operation. The outdoor heat exchanger 22, a control valve 31, and a refrigerant container 24 are arranged in series in this order. The outdoor heat exchanger 22 provides a passage in which a passage cross-sectional area of the refrigerant changes. When the outdoor heat exchanger 22 is used as a condenser, the flow direction of the refrigerant is a direction in which the passage cross-sectional area becomes relatively small. When the outdoor heat exchanger 22 is used as an evaporator, the flow direction of the refrigerant is a direction in which the passage cross-sectional area becomes relatively large. In both flow directions, the refrigerant container 24 acts as a receiver.
