PURPOSE:To carry out demisting in a short time while reducing change in the temp. of a vehicle room by controlling only a cooling means to be in a continuously operating condition for a set period of time at the time of a dewing condition and keeping vehicle room temp. control means except said cooling means in a condition before dewing. CONSTITUTION:A compressor 5 constitutes a part of a cooling means for cooling air to be blown into a vehicle room and is controlled in its driving by an arithmetic and control means 4 based on a vehicle room temp. control signal related to the difference between a vehicle room temp. from a detecting means 2 and a set vehicle speed temp. from a setting means 3. A humidity sensor 6 is provided in the vicinity of the inner face of a vehicle window and dewing on the inner face of the vehicle window is judged by a judging means 7 based on the detected output of the sensor 6. And, a set period of time from the time of generating the judged output is measured by a timer means 8 and, during this measuring period, the compressor 5 is continuously driven by a drive control means 9, prior to a drive control by means of a vehicle room temp. control signal. |
