Abstract
An air conditioning apparatus of an air mix type for automotive vehicles has two air conditioning mechanisms which are provided for an upper air outlet and a lower air outlet, respectively. The upper air outlet is split into a vent outlet and a defroster outlet, and a defroster/vent change-over door is mounted at the upper air outlet to switch the same between the defroster outlet and the vent outlet so that when one is open, the other is closed. A communication passageway is provided in the apparatus to connect the lower air outlet to the defroster outlet. A defroster door is mounted in the communication passageway to open and close the same so that part of the conditioned air at the lower air outlet can be transferred to the defroster outlet to ensure blow of conditioned air both through the defroster outlet and the vent outlet.
