HUMIDITY CONTROL DEVICE

摘要

A humidity control device (20), comprising an adsorbing rotor (24) and a heater (25) and a first passage (21) allowing first air to flow therein and a second passage (22) allowing second air to flow therein. When the rotational speed of the adsorption rotor (24) is controlled, a heat exchange rate and a moisture exchange rate between the first air and the second air are changed to switch an operation mode between a dehumidifying operation and a humidifying/heating operation. In the dehumidifying operation, the rotational speed of the adsorption rotor (24) is set low. The first air is supplied into a room after being dehumidified by the adsorption rotor (24), and the second air is discharged to the outside of the room after being utilized for the regeneration of the adsorption rotor (24). In the humidifying/heating operation, the rotational speed of the adsorption rotor (24) is set high. The first air is supplied into the room after receiving heat and moisture from the adsorption rotor (24), and the second air is discharged to the outside of the room after its heat and moisture are removed by the adsorption rotor (24).
