ABSTRACT OF THE DISCLOSURE An air cooling temperature control system for use in vehicles including a cooler having a compressor, a heater having an air-mix damper and a room air temperature regulator, in which feedback control is effected so that a room air temperature may coincide with a preset temperature value. The output of the heater is regulated to respond to sudden changes in the room air temperature by controlling the opening of the air-mix damper. The duty cycle of the compressor is regulated by a controller so as to respond to gradual changes in room air temperature while the output of the heater is at a low level and to incrementally decrease the duty cycle of the compressor when the output of the heater is above the low level, thereby driving the output of the heater down so as to minimize the counteracting effects of concurrent heating and cooling, so that the desired room air temperature is maintained with minimal energy.
