Abstract

A humidifier and an air conditioner using the humidifier, wherein, when the atmospheric temperature detected by an atmospheric temperature sensor (24) is higher than the room temperature detected by a room temperature sensor (22) and the atmospheric humidity is 90% or less allowing the inside of a humidifying hose to be dried, a drying operation is performed and, when the atmospheric humidity detected by an atmospheric humidity sensor (23) is higher than 90%, the drying operation is not performed because the inside of the humidifying hose (4) cannot be dried sufficiently even if the fresh air is blown into the humidifying hose (4), i.e., the drying efficiency is poor, and, when the atmospheric humidity detected by the atmospheric humidity sensor (23) is 60% or higher not allowing the inside of the humidifying hose (4) to be dried efficiently, the fresh air blown into the humidifying hose (4) is heated by a heater (17), whereby, even when the humidifying operation is not performed, a dew condensation can be prevented from occurring on the inside wall of the humidifying hose.
