PURPOSE:To substantially increase a demisting controlling zone by providing a relative humidity detecting means, a relative humidity detection propriety judging means, an inside air circulation mode selection detecting means and a demisting control means. CONSTITUTION:When the detection of a relative humidity is judged to be affirmation by a relative humidity detection propriety judging means 2 and the relative humidity detected by a relative humidity detecting means 1 is above a defined value, a demisting control means 3 performs the demisting control of a controlled object 4. Also, when the detection of the relative humidity is judged to be negative and the selection of an inside air circulation mode is detected by an inside air circulation mode selection detecting means 5, the demisting control means 3 performs the cloudiness preventing control of the controlled object 4 toward the accelerating side of a cloudiness preventing effect. |
