Abstract

An air conditioner system for automotive vehicles includes a blower control unit for adjusting discharge amount of conditioning air into the vehicular cabin depending upon the difference between the set cabin temperature and the cabin temperature, and for causing the discharge amount of fluctuate so as to increase and decrease when the difference between the temperatures is less than a predetermined value. The periods through which the discharge amount is greater than and less than predetermined values, respectively, are controlled depending upon the monitored insolation. The air conditioner system also includes an air flow direction setting unit for adjusting direction of the conditioning air discharge from a vent nozzle. The air flow direction setting unit is operable between a concentrated discharge air mode in which the air flow discharged from the vent nozzle is concentrated on the vehicular occupants, and a diffused discharge air mode in which it is diffused so as not to be concentrated on the occupants. The air flow direction setting unit is operated in accordance with the discharge amount.
