Abstract
An air conditioning apparatus of an air mix type for automotive vehicles includes a casing formed therein with an air passageway, a heating device mounted in the air passageway and an air mix door mechanism for suitably regulating air flowing through the heating device and air bypassing the same, and is adapted to provide an air mix or conditioned air by mixing warm air with cool air in suitable proportions so as to release the conditioned air of desired temperature through air outlets formed in the casing. The air passageway in the casing is divided along the direction of flow of the air to define a cool air heating passageway in which the heating device is disposed and a cool air passageway which is connected to the air outlets to directly lead the cool air thereto. The cool air passageway is equipped with a door mechanism for opening and closing the cool air passageway.
