Abstract
An air conditioning apparatus includes an air conditioning case having therein first and second air passages partitioned from each other. First and second fans are respectively disposed in the first and second air passages, and an outer diameter of the first fan is smaller than that of the second fan. Therefore, an air volume relative to a total pressure in the first fan is greatly changed as compared with the second fan. Thus, when an operation mode is switched from a foot air mode to a foot/defroster air mode or from the foot/defroster air mode to the foot air mode, an opening degree of a defroster door is changed slightly.
