Abstract
A rotation number deciding unit decides a rotation number of a cooling fan based on the result of detection by an intake air temperature sensor. A determining unit determines whether the degree of increase of intake air temperature is equal to or more than a threshold based on the result of detection by the intake air temperature sensor. When the determining unit determines the degree of increase of intake air temperature is equal to or more than the threshold, the controlling unit determines whether there is a possibility of occurrence of condensation based on the result of detection by the intake air temperature sensor and the result of detection by an intake air humidity sensor. When determining there is a possibility of occurrence of condensation, the controlling means causes the cooling fan to rotate at a rotation number lower than the rotation number decided by the rotation number deciding unit.
