ABSTRACT:
An automatic air conditioning system for automotive vehicles including discharge outlets for discharging conditioned air comprises a plurality of louvers utilizing a number of fins, a discharge outlet actuator for controlling the fins, and a controller for determining that the environmental conditions of the vehiclular cabin are in either, a cool-down state wherein a cabin temperature in the vehicular cabin is excessively higher than a target cabin temperature, a steady state wherein the cabin temperature is essentially equal to the target cabin temperature, or a transient state between the cool-down state and the steady state. The controller controls the discharge outlet actuator so as to vary the discharge mode of the conditioned air discharged from the discharge outlets in one of three discharge modes in response to the environmental conditions. The controller controls the discharge mode such that the occupant in the vehicular cabin can feel suitably cool under the environmental conditions in the vehicular cabin which is momentarily changed.
