ABSTRACT:
A vehicle air conditioner has an air conditioning unit. The unit has a blower unit and an heat exchanger. The unit has a defroster outlet opening and an outside air inlet opening. The unit also has a switching door. The unit has a first passage between the defroster opening and an upstream side of the blower unit, and a second passage between the defroster outlet opening and a downstream side of the heat exchanger. During an inside air suction mode, the outside air inlet opening is closed, and the first passage is opened and the second passage is closed by the switching door. Thus, inside air is sucked through the defroster outlet opening during the inside air suction mode.
