| description | A vehicle air conditioning apparatus includes: a refrigerant circuit including a compressor configured to compress refrigerant, an outdoor heat exchanger configured to perform a heat exchange between the refrigerant and outdoor air, and a heat absorption heat exchanger configured to absorb heat from a heat-absorbed subject; and a controller configured to control the refrigerant circuit. The controller can selectively perform a plurality of defrosting modes including: a hot gas defrosting mode to defrost the outdoor heat exchanger by the refrigerant compressed by the compressor; and a heat absorption defrosting mode to defrost the outdoor heat exchanger by the refrigerant absorbing the heat from the heat-absorbed subject and compressed by the compressor. The controller sets a hot gas defrosting priority condition to preferentially select the hot gas defrosting mode. |
