Here, the remainder of the air that has passed through the adsorption portion 15 of the humidity control rotor 11 is supplied with moisture when passing through the separation portion 14 to become humidified air, and is supplied indoors.

  The above operation is repeated by repeating the rotation of the humidity control rotor 11. Thereby, indoor humidification with no water supply is performed. Also, indoor clean air is supplied by supplying clean air outside the room.

<Dehumidification supply operation>
In the dehumidifying and supplying operation, as shown in FIG. 11, an eighth air flow A <b> 8 is generated by the blower fan 51.

  In this case, the air taken in from the outside passes through the adsorption portion 15 of the humidity control rotor 11. As a result, moisture is adsorbed on the adsorption portion 15. A part of the air that has passed through the adsorption portion 15 is supplied to the room as dehumidified air.

  On the other hand, a portion of the humidity control rotor 11 that has adsorbed moisture moves to a position heated by the heating unit 12 as the humidity control rotor 11 rotates, and becomes a detached portion 14. Here, the remainder of the air that has passed through the adsorption portion 15 of the humidity control rotor 11 passes through the separation portion 14, and moisture is separated from the separation portion 14 at this time. And the water | moisture content isolate | separated from the detachment | leave part 14 is discharged | emitted with the air to the outdoor.

  The above operation is repeated by repeating the rotation of the humidity control rotor 11. Thereby, indoor dehumidification which does not require the treatment of water can be performed. Also, indoor clean air is supplied by supplying clean air outside the room.

<Dehumidification exhaust operation>
In the dehumidifying and exhausting operation, as shown in FIG. 12, the ninth air flow A9 is generated by the blower fan 51.

  In this case, the air taken in from the room passes through the adsorption portion 15 of the humidity control rotor 11. As a result, moisture is adsorbed on the adsorption portion 15. A part of the air that has passed through the adsorption portion 15 is supplied to the room as dehumidified air.

  On the other hand, a portion of the humidity control rotor 11 that has adsorbed moisture moves to a position heated by the heating unit 12 as the humidity control rotor 11 rotates, and becomes a detached portion 14. Here, the remainder of the air that has passed through the adsorption portion 15 of the humidity control rotor 11 passes through the separation portion 14, and moisture is separated from the separation portion 14 at this time. And the water | moisture content isolate | separated from the detachment | leave part 14 is discharged | emitted with the air to the outdoor.

  The above operation is repeated by repeating the rotation of the humidity control rotor 11. Thereby, indoor dehumidification which does not require the treatment of water can be performed. In addition, exhausting indoor air is performed by discharging dirty air in the room to the outside.

In said 1st Embodiment, although the heating part 12 has opposed the left half of the humidity control rotor 11, you may arrange | position so that the right half may be opposed.

  Moreover, in 2nd Embodiment, although the heating part 12 has opposed the upper half of the humidity control rotor 11, you may arrange | position so that the lower half may be opposed.

(D)
In said 1st Embodiment, as shown in FIG. 14, 10th airflow A10 may be produced | generated by the 1st ventilation fan 21. As shown in FIG. The tenth air flow A10 is a flow of air supplied to the room through the adsorption portion 15 after the air taken in from the room and the air taken in from the outside merge. In this case, indoor dehumidification can be performed while supplying outdoor air into the room. In the tenth air flow A10, the air taken in from the room and the air taken in from the room may be merged after passing through the adsorption portion 15 and supplied to the room.
