Abstract

According to the present invention, in an air conditioning apparatus setting a double laminar mode in which an inside air and an outside air are blown while being partitioned, when the maximum heating state is set during an air outlet mode in which air is blown out simultaneously from both of a foot opening portion toward feet of a passenger and a defroster opening portion toward a windshield, a passage for conditioned air is partitioned into a first air passage for the inside air and a second air passage for the outside air. The first air passage is communicated with the foot opening portion, and the second air passage is communicated with the defroster opening portion. In the double laminar mode, at an air downstream side of a heating heat exchanger, there is formed a communication path communicating between the first air passage and the second air passage, and an amount of the outside air at the side of the second air passage is set to be larger than that of the inside air at the side of the first air passage, so that the outside air in the second passage flows into the first air passage through the communication path. In this way, it is possible to improve a defrosting performance of the windshield.
