ABSTRACT:
In an air-conditioner for automobiles, cooled air having passed through an evaporator is immediately introduced through a cooled air bypass passage into the vehicle passenger compartment. The opening of a bypass door disposed in the bypass passage is adjusted based on a head part total signal corresponding to a thermal load in the vicinity of the head of an occupant which is obtained in view of the current discharge mode, or an auxiliary total signal corresponding to a thermal load in the vehicle passenger compartment which is obtained in view of the current discharge mode. With this arrangement, the occupant does never feel excess cold when the discharge mode is changed and hence a feeling of comfortableness toward the air-conditioning can be maintained.
