VEHICLE AIR-CONDITIONING DEVICE

A vehicle air-conditioning device includes a blower which blows air to a vehicle cabin through blowout openings, a refrigeration circuit through which refrigerant is circulated by an electric compressor, an interior heat exchanger disposed in the refrigeration circuit and exchanging heat between the refrigerant and a blown air, which is air that is blown by the blower, an interior/exterior air adjustment device adjusting a ratio of interior air and exterior air contained in the blown air, and a first blowing control portion controlling the electric compressor to stop, controlling the blower to operate, and controlling the interior/exterior air adjustment device such that air that is blown into the vehicle cabin includes at least exterior air, when a temperature difference between a target temperature Tao of air that is blown through the blowout opening and an exterior air temperature Tam is less than a predetermined value. In this case, when the temperature Tao is close to the temperature Tam, the electric compressor is stopped and air including exterior air is blown by the blower. Thus, a reduction in electric-power consumption can be achieved and a temperature of the air can get closer to Tao.
