PURPOSE:To introduce the air outside a car into a car room without providing a new blower, and to obtain a comfortable air-conditioning effect keeping the head cool and the feet warm, by providing plural linking passages and plural passage converting means arranged between specific composition members respectively. CONSTITUTION:When a heating mode is operated, dampers 18 and 21 are driven to dotted line positions. That is, when the first damper 18 is driven to the dotted line position, the suction port of an exhaust blower 14 and the suction linking port 17 with its extension 16 are linked, while the suction port of the exhaust blower 14 and an exhaust inlet 12 are cut off. And when the second damper 21 is driven to the dotted line position, the exhaust outlet 16 and a blowoff linking port 20 are opened while the blowoff port of the exhaust blower 14 and an exhaust port 17 are cut off, and the extension 7a of a cool air linking passage 7 is linked to the blowoff port of the exhaust blower 14. Consequently, the air outside the car is introdusted from the exhaust outlet 15 to cool air flowing passages 2 and 3, and flows in to a car room 4 from cool air blowoff port group 5 and 6. |
