PURPOSE:To enable supplying the air having the set absolute humidity into a car compartment by drive-controlling an adjusting means for a cooler so that the humidity of the air passing through a cooler becomes equal to the calculated dew-point temperature according to the set absolute humidity. CONSTITUTION:A cooler M1 cools the air blown towards the car compartment, and an adjusting means M2 adjusts the cooling force of the passing air by the cooler M1. A humidity setting means M3 sets the aimed humidity in the car compartment, as the absolute humidity, and a calculating means 4 calculates the dew-point temperature at which the relative humidity becomes 100% according to the set absolute humidity. A control means M5 drives the adjusting means M2 and controls the temperature of the air passing through the cooler M1 to the dew-point temperature calculated. Therefore, the absolute humidity of the air passing through the cooler M1 becomes equal to the set absolute humidity. Therefore, even if the air passing through the cooler M1 is heated, the variation of the absolute humidity is suppressed. |
