PURPOSE:To improve comfortableness in a device, by constituting the device in such a manner that blown air, passing through a room cooling heat exchanger, is divided flowing to a room heating heat exchanger and a bypass passage through a temperature controlling damper and this damper is controlled to the direction of increasing a difference between car room temperature and outside air temperature at opening of a door and window in a vehicle. CONSTITUTION:Preset temperature 25, outside air temperature 26, car room temperature 27, door switch signal 29 and window switch signal 30 are input to a controller 24. When a signal opened with a door and window is input, an air conditioning device decides whether it is required for room heating operation or room cooling operation, and a control signal is output to an actuator 23 to regulate an opening of an air mixing damper 21 excessively of the control on the basis of preset temperature determined by the temperature setter 25 so that the air mixing damper 21 may increase opening at room heating and decrease opening at room cooling. In this way, even if the door and window are opened, temperature in a car room can be held approximately to the set temperature to improve comfortableness. |
