Abstract
A duct for leading air into a vehicle compartment is divided by a partition wall into two air passages. A first air passage is capable of taking in the exterior air while a second passage is capable of taking in only the interior air. In the duct, a cooling heat-exchanger is disposed at a downstream side of a blower unit, and a heating heat-exchanger is disposed at a more downstream side of the cooling heat-exchanger. A defroster air outlet opens at a downstream side of the first air passage, a foot-side air outlet opens at a downstream side of the second air passage, and a face-side air outlet opens between the cooling heat-exchanger and the heating heat-exchanger. A face-side door for opening and closing the face-side air outlet is capable of shutting off the air inlet side of the heating heat-exchanger.
