A vehicle air conditioner (1A) includes a heat pump circuit (2) including a compressor (11), an outdoor heat exchanger (13), an expansion mechanism (14), a first indoor heat exchanger (15), and a second indoor heat exchanger (16). The flow direction of a refrigerant in the heat pump circuit (2) is switched, by a switching member (12A), between a first direction in which the refrigerant discharged from the compressor (11) passes through the outdoor heat exchanger (13), the expansion mechanism (14), the first indoor heat exchanger (15), and the second indoor heat exchanger (16) in this order and returns to the compressor (11), and a second direction in which the refrigerant discharged from the compressor (11) passes through the first indoor heat exchanger (15), the expansion mechanism (14), the outdoor heat exchanger (13), and the second indoor heat exchanger (16) in this order and returns to the compressor (11). In the above-described configuration, the control of the expansion mechanism can be simplified during a heating operation and a cooling operation by handling a single expansion mechanism. |
