ABSTRACT:
An air conditioner system for an automotive vehicle is particularly adapted to insolation dependent correction of a discharge rate of the conditioning air in cold weather, such as in the winter so that an excessive flow rate of relatively cool air will never be discharged in response to insolation. The air conditioner system comprises a blower driver means for directing air passing an air heating means and/or cooling means toward a vehicular cabin, an ambient temperature detecting means for monitoring and detecting ambient air temperature outside of the vehicular cabin, an insolation detecting means for detecting the sun beam entering the interior space of the vehicular cabin, a warm-up state detecting means for detecting a warm-up condition in which a temperature of a conditioning air is to be discharged into the vehicular cabin, and a short period after initiation of discharging of conditioning air, an a control means for controlling the blower driver means for adjusting the discharge rate of the conditioning air into the vehicle cabin, the control means increasing the discharge rate according to an increase of intensity of the insolation and respnsive to the warm-up state detecting means detecting the warm-up condition, for disabling an increase of the discharge rate irrespective of an increase of the insolation intensity.
