Abstract

A humidifier requiring no feed water, which is capable of sufficiently cooling a moistening rotor to effect sufficient humidification even in low-temperature low-humidity winter. Cooled air cooled through the outdoor heat exchanger (22) of an air conditioner flows into a cooling passageway (21) extending through a cooling region (C), and a moistening rotor (12) is cooled in the cooling region (C) to a very low temperature. Utilizing the principle of the outdoor heat exchanger (22) of the air conditioner taking heat of evaporation from the outside air makes it possible to obtain cooled air; therefore, cooled air can be obtained without increasing cost and energy. The moistening rotor (12) cooled in the cooling region (C) has been cooled in the cooling region (C) with very low temperature air; therefore, even in winter when the outside air is at low temperature, the moistening rotor (12) is capable of collecting sufficient moisture from the outside air. The portion of the moistening rotor (12) which has sufficiently collected this moisture discharges the moisture to the high-temperature heated air in the moistening region.
