PURPOSE:To prevent windows from being clouded and accelerate the initial heating by operating a damper so that the inside air is guided to a foot blowout port while by-passing an evaporator and the dry outside air is heated and guided to a defroster blowout port in the heat mode. CONSTITUTION:In a heat mode, when a blowout mode lever is operated, in interlock with it, a damper 30 is set to the medium position 30a, and an inside/ outside air selector valve 17 is set to the 17c position. Thereby, the outside air is guided to the passage on an evaporator 42 side from an outside air passage 28, the flow to a heater core 54 is restricted according to the position 55a or 55b of a mix damper 55, and hot air is blown out through a defroster blowout port 61. On the other hand, the inside air passes an inside air guide port 16, a bypass passage 43, and hot air is blown out through a foot blowout port 63 according to the position 56a or 56b of a damper 56. According to this constitution, defrosting is performed by the dry outside air and the hot inside air is guided to the foot position, thus the initial heating can be accelerated while defrosting is performed. |
