Abstract: In an initial stage of a cool down operation of a vehicle air conditioner, a rapid cooling operation is performed while cool air is directly blown to a passenger from direct air outlets. In a later stage of the cool down operation of the vehicle air conditioner, a temperature of an inner wall portion of a passenger compartment is reduced while cool air is indirectly supplied to the passenger of the passenger compartment from the indirect air outlet. Accordingly, cool air can be locally blown to the passenger in the initial stage, and cool air can be supplied to the entire passenger compartment while restricting an adverse effect due to heat radiation of the inner wall portion in the later stage. Thus, operation performance of the air conditioner can be improved while comfortable air conditioning feeling can be given to the passenger in the passenger compartment.
