ABSTRACT:
An air conditioner system for automotive vehicles comprises a device for detecting the temperature of an inner part of the compartment of a vehicle which is exposed to the radiant heat of the sun, a device for detecting the temperature of another inner part of the compartment which is unexposed to the radiant heat of the sun, and a control unit whereby the difference between the temperature of the part exposed to the radiant heat of the sun and that of the part unexposed to the radiant heat of the sun is obtained and in accordance with this temperature difference and the desired preset temperature of amounts of heated and cooled air blown into the vehicle compartment are controlled so as to cause the temperature in the compartment to approach the preset value. The system further comprises a device for detecting the closed position of an on-off damper which controls the flow of air through the defroster air outlet whereby the control unit is operated in response to the closed position of the damper.
