  • Patent number: 10913331
    Abstract: A motor-driven vehicle includes an electric motor, a power storage device, a control device, and a refrigerant circuit. The refrigerant circuit has a compressor, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. The indoor heat exchanger exchanges heat with the refrigerant compressed by the compressor. The refrigerant which passes through the indoor heat exchanger is decompressed by the expansion valve, and the outdoor heat exchanger exchanges heat with the decompressed refrigerant and allows the refrigerant to return to the compressor. When the remaining capacity of the power storage device is equal to or more than a predetermined value, the control device operates the compressor and decreases a passing-through air volume of a first air guide device that controls a passing-through air volume of the outdoor heat exchanger.

  • Patent number: 10202018
    Abstract: A vehicle air conditioner includes a control device and a heating refrigerant circuit having: a compressor that compresses and discharges a suctioned refrigerant; an internal condenser that releases heat of the discharged refrigerant; an expansion valve that reduces a pressure of the refrigerant which passes through the internal condenser and that expands the refrigerant; and an external heat exchanger that exchanges heat between the refrigerant which passes through the expansion valve and external air and that causes the refrigerant after the heat exchange to return to the compressor. The opening degree of the expansion valve is controlled by the control device to be increased at a start of a heating operation to more than an ordinary opening degree during a heating operation to start the compressor, and after a set time elapses, to be caused to return to the ordinary opening degree during a heating operation.
