Abstract
An air conditioner system for automotive vehicles includes an air flow direction setting unit for adjusting direction of the conditioning air discharged 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 occupants of the front seats, and a diffused discharge air mode in which it is directed toward the sides of the vehicular cabin. As the difference between the set cabin temperature and the cabin temperature decreases, the voltage applied to a blower motor toward a predetermined minimum value, and thereafter fluctuates regularly or irregularly. The mode of the air flow direction setting unit is changed from the diffused discharge air mode to the concentrated discharge air mode, a predetermined time before the voltage applied to the blower motor increases beyond a predetermined set value, and it is changed from the concentrated discharge mode to the diffused discharge air mode, when or a predetermined time before the voltage applied to the blower motor falls below the predetermined set value.
