- the operation rate is improved by eliminating the drying operation, the humidification capacity can be improved, and the residual moisture is prevented by preventing the dew condensation in the humidification duct 4. This can also prevent the generation of force-induced vibration.
- the rotation speed of the suction fan 13 is controlled as the actuator control for adjusting the absolute humidity of the humidified air.
- the rotation speed of the humidification rotor 11 is controlled. It may be controlled to raise and lower.
- the humidifying device of the invention may adjust the absolute humidity of the humidified air by controlling at least one of the number of rotations of the humidification rotor, the number of rotations of the suction fan, the number of rotations of the desorption fan, and the input of the heater.
- an air conditioner using a humidifier has been described.
- the humidifier of the present invention may be used for another heating device, or may be used alone.
- the present invention may be applied to a humidifying device or the like.
- the inlet humidity sensor 21 as a humidified air humidity sensor and the inlet temperature sensor 24 as a humidified air temperature sensor are arranged on the inlet side of the humidifying duct 4 as a transfer passage.
- the humidified air humidity sensor and the humidified air temperature sensor need only be arranged in the transport passage.
- the humidifying device of the present invention is not limited to the configuration disclosed in the first and second embodiments, and it is needless to say that the present invention may be applied to a humidifying device having another configuration. It is.
