霜運転をしている。In the heat pump heating mode,
Since the temperature of the refrigerant in the outside air heat exchanger becomes low, the dehumidified water from the air forms frost and freezes on the outside air heat exchanger, making it impossible to exchange heat with the outside air heat exchanger. It is necessary to perform a defrosting operation for removing frost and icing of the vehicle outdoor air heat exchanger. For example, in a home room air conditioner, the four-way switching valve is switched in the same manner as in the cooling mode, and the outdoor air heat exchanger is heated to a high temperature to perform a defrosting operation. In addition, during the defrosting operation, if the outdoor air heat exchanger exchanges heat with air, it cannot be defrosted,
The blower for the outdoor air heat exchanger is stopped to perform the defrosting operation in the heating mode.

房モードでの除霜運転が可能となる。When necessary, the motor exhaust heat can be used effectively, and the sensible heat in the ventilation circuit increases due to the motor exhaust heat, so that the relative humidity decreases, so that frost formation becomes difficult and the defrosting operation time is shortened. Further, during traveling, the wind on the front side and the wind on the rear side of the outside air heat exchanger can be shut off, so that the defrosting operation in the heat pump heating mode can be reliably performed.

暖房能力、効率の向上となる。When necessary, the motor exhaust heat can be used effectively, and the sensible heat in the ventilation circuit increases due to the motor exhaust heat, so that the relative humidity decreases, so that frost formation becomes difficult and the defrosting operation time is shortened. In addition, since the wind on the front side and the wind on the rear side of the outside air heat exchanger can be shut off during traveling, the defrosting operation in the heat pump heating mode can be reliably performed. Further, when the vehicle stops, the air volume of the air heat exchanger outside the vehicle compartment can be increased, and the cooling and heating capacity and efficiency can be improved.
