A defogging device of a vehicle air-conditioning system is provided to completely removing fogging even if a defogging condition is changed to minimize the frequency of generation of fogging. A defogging device of a vehicle air-conditioning system includes a defog sensor(1), a controller(9) and an outdoor air temperature sensor(20). The defog sensor senses the humidity of the inner side of a glass pane. The controller turns on/off an air conditioner or opens/closes a def door(3) according to the humidity of the glass pane. The outdoor air temperature sensor senses the outdoor air temperature of a vehicle. |
