To provide a vehicle air-conditioning apparatus capable of achieving energy saving.
In the case that there are no passengers on seats other than a driver seat and a heated air temperature is lower than a target exhaled air temperature, a frontal passenger seat-side outlet is closed and a one-seat concentrated mode for exhaling an air-conditioning wind from a driver seat-side outlet is executed. In this case, compared with a standard air-conditioning mode time during which an air-conditioning wind is exhaled from the driver seat-side outlet and the frontal passenger seat-side outlet, electric power supplied to an air blower for the same heat load is set small. By this, it is possible to reduce power consumed by an electric motor of the air blower and to achieve energy saving. Besides, in the case that there are no passengers on the seats other than the driver seat and the heated air temperature is higher than the target exhaled air temperature, a standard air-conditioning mode is executed. In this case, an exhaled air amount from the driver seat-side outlet is relatively decreased while an exhaled air amount from the frontal passenger seat-side outlet is relatively increased.
