Abstract
A control apparatus of an air conditioner for automobiles comprises: means for calculating a room temperature difference signal; means for calculating a reference blowout temperature; means for correcting the reference blowout temperature, thereby calculating a target blowout temperature; and means for controlling the heat exchanger such that the difference between the target blowout temperature and the actual blowout temperature becomes zero. This control apparatus can always maintain and manage the blowout air temperature at which the passenger can feel most comfortable for various ambient temperature conditions.
