ABSTRACT:
An automatic climate control system for the passenger compartment of a motor vehicle includes an ambient temperature sensor, an vehicle-interior temperature sensor, a sunload sensor, a temperature selector by which a vehicle passenger may select a desired interior temperature, and a variable-speed blower fan for directing air into the passenger compartment. The operating speed of the blower fan is controlled by the system control unit so as to achieve the desired temperature within the passenger compartment while otherwise capitalizing on the temperature effects of the exterior environment, i.e., ambient temperature and sunload, to minimize blower fan noise and resultant directed airflow.
