PROBLEM TO BE SOLVED: To provide a humidifier free of water supply, which can fully cool a humidifying rotor and can humidify sufficient, even in winter at low temperature and low humidity. SOLUTION: A cooling air current is cooled through the outdoor heat exchanger 22 of an air conditioner and flows in the cooling passage 21 of a cooling region C. A humidifying rotor 12 is cooled to very low temperature in the cooling region C. Since this humidifier obtains the cooling air by utilizing the outdoor heat exchanger 22 of the air conditioner robbing the outside air of the heat of evaporation, cooled air can be obtained, without increasing cost and energy. Since in the humidifying rotor 12, which is cooled in the cooling region C, is cooled with air at very low temperature in the region C, the humidifying rotor 12 can fully collect moisture from the outside air, even in the winter when the outside air is at very low temperature. This section of the humidifying rotor 12 with fully collected moisture discharges moisture into heated air at high temperature in a humidified region. |
