PURPOSE:To improve comfortableness and to prevent a window from blurring when an air conditioner is started, by opening a defrost blow port, when an engine cooling water temperature is in a predetermined value of less, while also a foot blow port, when the cooling water temperature is in the predetermined value or more and a blown air amount is in a predeteramined value or less, and only the foot blow port if the blown air amount increases to the predetermined value or more. CONSTITUTION:A decision means 31 decides whether or not a blower 4 is in starting of room heating, and if it is in a starting control of room heating, voltage of the blower 4 is compared with a predeteramined value by a detecting means 32. And when the voltage is in the predetermined value or more, only a foot flow port 3C is opened as a heater mode. When the voltage is in the predetermined value or less with a cooling water temperature in a predetermined value or less, a mode setting means 34 opens only a defroster blow port 3A. The cooling water temperature increases to the predeteramined value or more, and if a blown air amount of the blower 4 is in a predetermined value or less, the defroster blow port 3A and the foot blow port 3C are opened. By this constitution, an air conditioning unit, when it is started, performs a control of keeping the head cool and the foot warm further enables a window to be prevented from blurring. |
