PURPOSE:To prevent the occurrence of hunting for repeating humidifying control and dehumidifying control in humidifying/dehumidifying control by correcting previously set upper limit value and lower limit value for carrying out the high humidity judgment and low humidity judgment in a vehicle room based on the cloudiness generating condition of a window glass. CONSTITUTION:The relative humidity in a vehicle room is detected by a means 45 while detecting a condition for generating the cloudiness of a window glass with a means 46. Based on the condition detected by the means 46, the upper limit value and lower limit value of a previously set humidity are corrected by a means 11A. The upper limit value corrected by the means 11A and relative humidity detected by the means 45 are compared and judged by a means 11B and, when the relative humidity is above the upper limit value, a means 55 is driven to carry out dehumidifying control. Further, the lower limit value corrected by the means 11A and relative humidity detected by the means 45 are compared and judged by a means 11C and, when the relative humidity is below the lower limit value, a means 56 is driven to carry out humidifying control. |
