ABSTRACT:
An intake air control device in an automotive air-conditioning apparatus includes an intake damper angularly movable selectively into a first position for circulating air in the passenger compartment of an automobile, a second position for introducing only ambient air into the passenger compartment, and a third position for introducing a smaller amount of ambient air into the passenger compartment than the amount of ambient air introduced by the intake damper in the second position. When air-conditioning control is commanded while only ambient air is being introduced, the intake damper is controlled to move to the third position for introducing a smaller amount of ambient air than the amount of ambient air introduced by the intake damper in the second position.
