ABSTRACT:
In an air conditioning apparatus for a vehicle, a double layer flow mode is set when the maximum heating state is set during an air outlet mode where both a foot opening portion and a defroster opening portion are opened. During the double layer flow mode, an air passage of an air conditioning case is partitioned into a first air passage through which inside air flows and a second air passage through which outside air flows, in such a manner that the first air passage communicates with the foot opening portion and the second air passage communicates with the defroster opening portion. When the double layer flow mode is set, the maximum rotation speed of a blower for blowing air is reduced by a predetermined level as compared with an entire outside air mode or an entire inside air mode. Thus, heating capacity for a passenger compartment of the vehicle can be improved.
