  • 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: 7017659
    Abstract: A vehicle air-conditioning system adjusts the temperature at an outlet by a combined amount of air flowing through a first bypass passage adjusted by an air mixing door and air flowing through a second bypass passage adjusted by a cool air adjusting door independently of the first bypass. A cool air adjusting door control unit adjusts the opening of the cool air adjusting door so that the temperature detected by a discharge temperature sensor comes closer to a target discharge temperature for precise control of discharge temperature, and also causes the cool air adjusting door to be fully open when the opening of the air mixing door determined by an air mixing door opening setting unit is equal to or smaller than a predetermined degree of opening, so as to maintain a steady amount of air discharged from the outlet.
