Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram for explaining a dehumidification / humidification method using plasma. To describe the dehumidifying / humidifying method of the present invention, first, when the place where dehumidification is required is, for example, a room (I), moisture in the air is absorbed by an adsorbent such as zeolite in the room (I). ) To dehumidify. This adsorbent is used, for example, in a form mixed with a binder and formed into a plate-shaped filter, or used as a form carried on the surface of a honeycomb structure described later.
Hereinafter, these forms are collectively referred to as an adsorption structure (11), and the dehumidification / humidification device (A) is configured by including the adsorption structure (11) and the plasma generator (21). Therefore, when the interior (I) is dehumidified, humid air containing a large amount of moisture in the interior (I) is sucked into the adsorption structure (11) from one side to be adsorbed by the adsorbent, and the moisture is removed and dried. The discharged air is discharged into the room (I) from the opposite side of the adsorption structure (11) to dehumidify the room (I). The adsorbent adsorbs a large amount of water by dehumidification and approaches a saturated adsorption state. Before the adsorbent enters the saturated adsorption state, the power supply (22) of the plasma generator (21) is turned on to turn on the adsorption structure. A voltage of, for example, 5 to 10 V is applied between a pair of electrodes (23) arranged on both sides of (11) to generate plasma, and the plasma is applied to the adsorbent to remove water from the adsorbent. The air containing a large amount of the desorbed moisture is released to the outdoors (O) as a place where the moisture can be released.

On the other hand, when the indoor (I) is humidified, the location for obtaining the moisture for humidification is the outdoor (O). In this case, the moisture in the outdoor (O) air is absorbed by the adsorbing structure (11). )
Before the adsorbent is brought into a saturated adsorption state, the power supply (22) of the plasma generator (21) is turned on and the adsorbent is disposed on both sides of the adsorbent structure (11) before the adsorbent enters a saturated adsorption state. A voltage of, for example, 5 to 10 V is applied between the pair of electrodes (23) to generate plasma, and the plasma is applied to the adsorbent to remove moisture from the adsorbent. The air containing a large amount of the desorbed moisture is introduced into the room (I) where humidification is required, and humidifies the room (I).

The mechanism of water desorption by the plasma generator (21) is as follows. That is, the moisture adsorbed on the adsorbent of the adsorbing structure (11) is excited by the plasma discharge generated between the adsorbents, and takes on a negative charge. Since nitrogen and oxygen in the air flow as N radicals and O radicals around the adsorbent due to the plasma discharge, the excited moisture is induced by these N radicals and O radicals and desorbs from the adsorbent. In addition, since the flow of electrons is generated by the plasma discharge, the excited moisture is also attracted to free electrons and is desorbed from the adsorbent.

As described above, since the water is desorbed from the adsorbent by the discharge energy of the plasma, the running cost can be greatly reduced as compared with the method in which the adsorbent is heated by thermal energy. Further, there is no decrease in air temperature or dehumidification performance as in the air cooling system, and no burns are generated in the steam introduction system, and a great deal of labor for water injection can be eliminated.

(Second Embodiment of Dehumidifying / Humidifying Apparatus) FIG. 3 shows a dehumidifying / humidifying apparatus (A) according to a second embodiment. This dehumidifying / humidifying device (A) includes an adsorption structure (11) and a plasma generator (21) as in the first embodiment.
Unlike the suction block (11A) of the first embodiment, the suction structure (11) is formed of a disk-shaped suction rotor (hereinafter, denoted by reference numeral 11B). However, this suction rotor (11B) is made of a honeycomb core material made of an aluminum alloy or the like, and has a large number of ventilation holes (12) penetrating on the front and back sides. It is similar to the suction block (11A) in that it is adhered and carried.

The electrode (23) of the plasma generator (21) is connected to the air hole (1) of the suction rotor (11B).
Embodiment 2 is the same as Embodiment 1 in that it is constituted by a wire mesh having a number of ventilation passages (23a) parallel to 2), but here, the electrode (23) is
1B) is different from the first embodiment in that it is arranged corresponding to a part of the ventilation holes (12). The ratio of the electrode (23) to the suction rotor (11B) is small, and the ventilation area of the suction rotor (11B) where the electrode (23) does not correspond to the electrode (23) in the suction rotor (11B). Is larger than the corresponding part.

Further, while the electrode (23) is fixed, the suction rotor (11B) is rotatable.
The rotation changes the position of the ventilation surface with respect to the electrode (23). Contrary to the above, the electrode (23) is configured to be rotatable by fixing the suction rotor (11B), and the electrode (23) is rotated to rotate the electrode (23) with respect to the ventilation surface of the suction rotor (11B). 23) The position may be changed, and furthermore, the suction rotor (11
Both B) and the electrode (23) may be configured to be relatively movable such that the position of the electrode (23) with respect to the ventilation surface of the suction rotor (11B) is variable.

In the dehumidifying and humidifying apparatus (A) according to the second embodiment, for example, the water in the room (I) is removed at a place (upper part in FIG. 3) where the electrode (23) of the suction rotor (11B) does not correspond. The air containing a large amount is introduced into the ventilation hole (12) of the adsorption rotor (11B) as shown by the arrow in the upper left of FIG. 3 to adsorb moisture with the adsorbent, and the dried air from which the moisture has been removed is drawn by the arrow in the upper right of FIG. As shown in the room (I).

When the suction operation proceeds, the suction rotor (11)
The adsorbent (B) approaches the saturated adsorption state, but it is necessary to desorb water from the adsorbent before the adsorbent enters the saturated adsorption state. In the desorption operation, the suction rotor (11B) is rotated to rotate the suction rotor (11B) to the saturated adsorption state, and the electrode (2

Otherwise, the configuration is the same as that of the second embodiment. Therefore, the same components are denoted by the same reference numerals, and detailed description thereof will be omitted.

In addition, the air is discharged outside (O) from above the adsorption cylinder (11C). The arrow at the lower right of FIG. 5 (a) indicates that air containing a large amount of moisture in the room (I) is adsorbed, and the direction is different, but is the same as the upper left of FIG. 5 (a). It represents that.

At the same time as the suction operation proceeds in the dehumidifying / humidifying unit (31) on the left side of FIG. 5 (a), the desorbing operation proceeds in the dehumidifying / humidifying unit (31) on the right side of FIG. 5 (a). )
