ABSTRACT:
An air conditioner system for a vehicle having an occupant compartment which includes a driver's occupying area and a front passenger's occupying area. The system includes a vent duct adapted to conduct a conditioned air. The vent duct defines a first passages opening to the driver's occupying area and a second passage opening to the front passenger's occupying area. First and second vent valves are disposed within the first and second passages, respectively. First and second actuators are drivingly connected to the first and second vent valves. A first sensor is so constructed and arranged as to detect insolation magnitude within the driver's occupying area and generate a first sensor signal indicative of the detected insolation magnitude within the driver's occupying area. A second sensor is so constructed and arranged as to detect insolation magnitude within the front passenger's occupying area and generate a second sensor signal indicative of said detected insolation magnitude within the front passenger's occupying area. A control unit is provided to determine target degrees of opening which the first and second vent valves are to take in response to the first and second sensor signals and providing first and second outputs to the first and second actuators, respectively, to set the first and second vent valves at the determined target degrees of opening.
