Abstract
When target blowout temperature to the inside of a vehicle is over a predetermined temperature in, an air temperature control system according to the present invention controls a cooling-ability controller to control air temperature of air cooled by a heat exchanger for cooling so that airflow becomes a predetermined temperature, and reduces the amount of blowout air into the vehicle per unit time compared with the amount of the blowout air when the target blowout temperature is under the predetermined temperature. Accordingly, the cooling air temperature due to the heat exchanger for cooling is fixed at the predetermined temperature even when the target blowout temperature is over the predetermined temperature. Therefore, generation of malodors due to dust and mold in the heat exchanger for cooling is prevented.
