Abstract: A vehicle air conditioner includes an external air introduction port, an internal air introduction port, an internal/external air-switching door, an air blower, a plurality of types of blowing ports, an internal/external air changeover switch, and a control device. The plurality of types of blowing ports blow conditioning air from a place that corresponds to a selected blowing mode. Even in a case where the internal/external air changeover switch is operated such that the external air introduction port is opened, when a blowing mode that opens a predetermined blowing port having a large total opening area among the blowing ports is selected and when an output of the air blower is equal to or more than a predetermined value, the control device controls the internal/external air-switching door such that the internal air introduction port is partially opened.

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.
