Abstract
A work vehicle includes a condenser, a fan, a variable mechanism, a fan control unit, an outside air temperature sensor, and a storage unit. The condenser cools a cooling medium used in an air conditioner. The fan cools the condenser. The variable mechanism can change a number of rotations of the fan. The fan control unit controls the variable mechanism. The storage unit stores a plurality of control maps for setting the number of rotations of the fan to respective different numbers of rotations of the fan in accordance with the outside air temperature detected by the outside air temperature sensor. The fan control unit controls the variable mechanism in accordance with one control map selected from the plurality of control maps stored in the storage unit based on an operating state of the air conditioner, to control the number of rotations of the fan.
