For example, it is set to 450 W, whereby the temperature of the dry air B blown into the room from the outlet 4 after dehumidification and drying is about 6 degrees higher than the room temperature.

In the above embodiment, the rotary type dehumidifying element 20 is installed vertically, but as another example, the rotation center axis O of the rotary type dehumidifying element 20 is set in the vertical direction. It is also possible to install it horizontally so that it can be pivoted and horizontally rotated, and its choice is arbitrary.

The diameter of the rotary type dehumidifying element 20 is as follows:
The rotation speed, the angle ratio θ1: θ2: θ3 of the dehumidification processing part 20A, the regeneration processing part 20B, and the heat recovery processing part 20C, and the air flow (m ³ /) between the dehumidification processing part 20A and the regeneration processing part 20B
