PROBLEM TO BE SOLVED: To automatically blow off foreign matters such as fallen leaves, etc., fallen on a condenser intake port and to eliminate failure such as clogging the condenser intake port by inversely rotating a condenser fan by a switch means for switching the rotation direction in starting. SOLUTION: A condenser unit 1 is mounted on a roof of a bus vehicle and a condenser 4, a condenser fan 5, etc., are arranged between a top and a bottom case 2, 3. The condenser 4 sucks an outside air from an intake port A in its upper face and emits the outside air passing through the condenser 4 from an outlet B. The condenser fan 5 is so provided as inversely rotating the condenser fan 5 for a prescribed time by a controller in an initial state of starting a cooler. When the condenser fan 5 is inversely rotated, the outside air flow upward from the bottom of the condenser 4, to blow off fallen leaves, etc., fallen on the intake port A in parking, etc., to eliminate the failure such as lowering of the capacity of the condenser 4.
