Abstract:
An air temperature control system for a vehicle, comprising:a blower for generating an air flow;an air passage for receiving air generated by said blower into a passenger compartment of said vehicle;a cooling heat exchanger, disposed inside said air passage, for cooling air in said air passage; andcooling ability adjusting means for adjusting an air cooling ability of said cooling heat exchanger so that air cooling temperature cooled by said cooling heat exchanger becomes a target blowout temperature to said vehicle compartment;wherein when said target blowout temperature is higher than a predetermined temperature, said cooling ability adjusting means is controlled so that said air cooling temperature cooled by said cooling heat exchanger reaches said predetermined temperature, said cooling ability adjusting means also controlling said blower so that a blowout air amount per unit time to said vehicle compartment is reduced in accordance with a rise in the target blowout temperature, said cooling ability adjusting means controlling a temperature of said passenger compartment by regulating a temperature of said cooling heat exchanger when said target blowout temperature is above said predetermined temperature, said cooling ability adjusting means controlling said temperature said passenger compartment by regulating said blowout air amount per unit time from said blower when said target blowout temperature is below said predetermined temperature.
