ABSTRACT:
A blowout temperature control apparatus of an air conditioner for automobiles comprises blowout temperature control means including blowout mode detecting means for detecting one of the outlet ports associated with blowout air temperature detecting means through which delivery of air is being stopped and generating a blowout stop signal, and blowout stop timed control means, responsive to the generation of the blowout stop signal, for controlling an air mixing door associated with the outlet port to temporarily change the amount of heat exchange of the heat exchanger to a reference level (Full Cool) and again change the heat exchange amount to a predetermined constant level complying with individual blowout modes and for maintaining the heat exchange amount at the constant level while the blowout stop signal is valid.
