ABSTRACT:
An air-conditioning apparatus for a passenger compartment of a vehicle includes an air duct having an inlet for receiving air to be conditioned, an air conditioner, and both face and foot outlets for supplying conditioned air into the passenger compartment. The air conditioner controls temperatures of the conditioned air from the face outlet and the foot outlet independently. The required temperature of the conditioned air from the independently controlled foot and face outlets is computed based on an inside air temperature, an outside air temperature, and the temperature set in the passenger compartment. A target supply air-temperature is computed in a bi-level mode based on an amount of sunlight in the passenger compartment, and is corrected as between the foot and face outlets such that air from the face outlet compensates for temperature differentials as between the passenger's feet and face due to sunlight, etc. In this way, a linear relationship is maintained between the correction amount of the temperature of the conditioned air and the temperature a passenger feels in the bi-level mode.
