PURPOSE:To contrive to improve heating function, window defrosting performance in a heating mode by a method wherein flow-off air quantity necessary for defrosting a window is determined by peripheral conditions both in air conditioning and defrosting to control the opening of a defroster damper. CONSTITUTION:Microcomputer 28 determines the target flow-off air temperature and air quantity from imputted preset temperature 60, open air 62, indoor air 64, car speed 74, solar heat quantity 66 and control signals are outputted respectively to fan controller 63, air mix damper actuator 52 to keep the flow-off temperatures of flow-off ports 18, 20, 22 under the target temperatures. The temperature 72 of the window surface 23, the humidity 70 near the window surface are inputted into the microcomputer 28, and the microcomputer operates the flow-off air quantity VD from the defroster flow-off port 22 to adjust the opening of the defroster damper 26. The window defrosting performance as well as the heater function in the heating mode can be improved by such constitution. |
