Abstract
A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on. The vehicular air conditioning is capable of implementing a quick warming of the in-vehicle device without impairing the heating feeling of occupant.
