ABSTRACT:
A vehicle air conditioner includes a main blower and a sub-blower for blowing air into a passenger compartment. The main blower is disposed to blow conditioned air in a front air passage toward a front seat area in the passenger compartment, and the sub-blower is disposed in a rear air passage having an air flow resistance larger than that in the front air passage so that a part of air blown by the main blower is blown by the sub-blower toward a rear seat area in the passenger compartment through the rear air passage. In the air conditioner, an air amount blown by the sub-blower is controlled to be increased in accordance with a decrease of an air amount blown by the main blower. Therefore, automatic control of the air amount blown by the sub-blower can be accurately performed.
