Abstract:
1. A vehicle air conditioner for cooling and heating a cabin, comprising: a heat pump circuit including: a compressor for compressing a refrigerant; an outdoor heat exchanger for performing heat exchange between the refrigerant and air outside the cabin; an expansion mechanism for expanding the refrigerant; and a first indoor heat exchanger and a second indoor heat exchanger each for performing heat exchange between the refrigerant and air blown into the cabin by a fan; and a switching member, provided in the heat pump circuit, for switching a flow direction of the refrigerant in the heat pump circuit between a first direction and a second direction, the first direction being a direction in which the refrigerant flows (a) from the compressor to the outdoor heat exchanger, (b) from the outdoor heat exchanger to the expansion mechanism, (c) from the expansion mechanism to the first indoor heat exchanger, (d) from the first indoor heat exchanger to the second indoor heat exchanger, and (e) from the second indoor heat exchanger before returning to the compressor, and the second direction being a direction in which the refrigerant flows (a) from the compressor to the first indoor heat exchanger, (b) from the first indoor heat exchanger to the expansion mechanism, (c) from the expansion mechanism to the outdoor heat exchanger, (d) from the outdoor heat exchanger to the second indoor heat exchanger, and (e) from the second indoor heat exchanger before returning to the compressor.
