Abstract: An air-conditioning unit for a vehicle that has an idling stop function includes a blower fan; first and second air-outlet ports configured to permit air blown from the blower fan toward first and second portions of a vehicle cabin, respectively; and an air-conditioning controller. The air-conditioning controller is configured to set a target air-outlet port temperature of the air blown from the ports on a basis of a preset temperature and an environmental condition of the vehicle; and, if the blower fan is operating to blow air from both of the ports before the vehicle is brought into an idling stop state, and then the vehicle is brought into the idling stop state, cause a controlled reduction in an air volume blown from at least one of the ports during the idling stop state; and cancel the controlled reduction when the idling stop state is cancelled.

Abstract: During a no-idling state, the opening of an air mix door is corrected in such a direction as to prolong a period of time in which the state of air conditioning before the no-idling state is sustainable, according to the state of air conditioning before the no-idling state and a target blow-off temperature during the no-idling state. Thereby, even when a compressor is stopped, a period of time in which a feeling of coolness or warmth is sustainable is prolonged, thus prolonging a no-idling time.
