ABSTRACT:
Whether the rear seat in a passenger compartment of a motor vehicle is occupied or not is sensed and, if not, a mode door adapted to control the proportion of air flows through upper and lower outlets of an air flow duct is suitably controlled such that the amount of air blown out from the lower outlet into the passenger compartment is increased relative to that from the upper outlet which will direct the air toward the rear end of the passenger compartment. Additionally, the temperature for turning the compressor on and off are shifted to slightly higher levels compared with the temperatures at which the compressor would be turned on and off if the rear seat were occupied.
