Description

  The present invention relates to a humidity control panel that adjusts the humidity of indoor air in a building.

Recent buildings such as residences have a tendency toward high heat insulation and high airtightness, resulting in the occurrence of condensation, mold, and mites caused by them, and humidity control in the building is an important issue. .
In view of this, a humidity control panel having a humidity control function used for interior building materials of buildings has been proposed.
For example, Patent Document 1 below proposes a panel in which charcoal or the like is packed in a partition partitioned by a partition plate, and a breathable covering sheet is attached to the front and back surfaces.
On the other hand, Patent Document 2 below proposes a wall structure in which a ventilation layer is provided between a ventilation inner wall material of a building and an inner surface of a wall surface heat insulating member, and an adsorbent is incorporated in the ventilation layer. In this device, an exhaust fan is attached to the wall surface of the attic, and the exhaust fan allows outside air or room air to pass through the ventilation layer through the opening provided in the base or the room, and to pass through the attic. It is configured to exhaust outside.

Japanese Patent Laid-Open No. 10-8633 (see FIG. 1) Japanese Patent Laid-Open No. 2001-140368 (see FIG. 1)

The conventional humidity control panel as described in Patent Document 1 is configured to absorb and release moisture using natural convection of air in the indoor space, and efficiently and actively condition the air in the indoor space. It was difficult.
Moreover, in what was described in the said patent document 2, although it is set as the structure which takes in air actively to a ventilation layer using an exhaust fan etc., it is concerned with the whole structure of a building, There was a problem that the whole structure was complicated.

  This invention is made | formed in view of the said situation, and it aims at providing the humidity control panel which can humidity-control the air of indoor space efficiently.

  In order to achieve the above object, a humidity control panel according to the present invention includes an air intake port provided at one end of the panel, an air exhaust port provided at the other end, a blowing means, a surface side in the internal space of the panel, and A first air passage that is provided along one of the rear surfaces and into which air from the air inlet is introduced, and a second air that is provided along the other and blows air toward the air outlet. The air passage is provided between the first air passage and the first air passage and the second air passage, holds the humidity control material, passes the air blown through the first air passage, and leads to the second air passage. And a humidity-controlling material holding layer.

By adopting such a configuration, the indoor air taken in from the intake port is introduced into the first air blowing path, is conditioned (dehumidified or humidified) in the humidity control material holding layer, and is led to the second air blowing path. Then, the air is blown through the second air passage and is discharged from the exhaust port into the room. Therefore, by installing the humidity control panel as a partition or the like in a suitable place in the room or using it as an interior building material, the air can be efficiently conditioned while circulating and stirring the indoor air. it can.
Moreover, since the air introduced into the 1st ventilation path from the inlet port passes through the humidity control material holding layer and is led out to the second ventilation path, for example, either the front side or the back side of the panel internal space Compared to the case where a ventilation path is provided only on one side and a humidity control material holding layer is provided on the other side, air can be efficiently contacted with the humidity control material, and moisture absorption and desorption can be improved efficiently. Can do. Moreover, since the air passages are provided on the front surface side and the back surface side of the humidity control material holding layer, even when there is a temperature difference between the front and back surfaces of the humidity control panel, it is possible to prevent the occurrence of condensation in the panel internal space. Can do.

In the present invention, the thickness of the humidity control material holding layer may be increased from the upstream side to the downstream side so that the first air passage narrows from the upstream side to the downstream side.
With such a configuration, a large pressure loss occurs in the air passage narrowed on the downstream side, and a large pressure loss also occurs on the downstream side when passing through the humidity-controlling material holding layer having a large thickness. Will grow dramatically. As a result, the air introduced into the first air passage from the intake port is less likely to be biased downstream and pass through the humidity control material holding layer when being blown through the first air passage. And pass through the moisture-conditioning material holding layer. That is, the amount of air passing through each part along the air blowing direction of the first air passage in the humidity control material holding layer can be made uniform, and indoor air can be more efficiently conditioned.

Moreover, in this invention, you may make it provide the baffle plate which narrows the said 1st ventilation path in steps toward the downstream from an upstream side at intervals along the ventilation direction of the said 1st ventilation path. .
With such a configuration, the baffle plate dramatically increases the pressure loss on the downstream side, and the baffle plate holds the air conditioning direction of a part of the air blown through the first air passage. It also functions as an airflow dispersion means for changing to the layer side. As a result, similarly to the above, the air introduced into the first air passage from the intake port is appropriately dispersed and passes through the humidity conditioning material holding layer, so that the indoor air can be more efficiently conditioned.

In the present invention, the humidity control material held in the humidity control material holding layer may be in the form of a powder and the particle size may be reduced from the upstream side toward the downstream side. .
With such a configuration, the pressure loss dramatically increases on the downstream side, and the air introduced into the first air passage from the intake port is appropriately dispersed to form the humidity control material holding layer as described above. It can pass through and the indoor air can be conditioned more efficiently.

Moreover, in this invention, the said humidity control material holding layer shall be equipped with many accommodation cells divided in multiple steps in the ventilation direction of the said both ventilation paths, and it accommodates the said humidity control material in this accommodation cell. It may be.
With such a configuration, the humidity control material can be efficiently filled into the humidity control material holding layer.
In addition, when the humidity control panel is applied to a vertical panel that is installed so that the intake and exhaust ports are positioned vertically, the humidity control panel is accommodated in a large number of accommodating cells that are partitioned in multiple stages in the air blowing direction of both air passages. Therefore, the bias due to the weight of the humidity control material can be reduced.

  Since the humidity control panel according to the present invention is configured as described above, the air in the indoor space can be efficiently conditioned.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a humidity control panel 1 according to the first embodiment, and the humidity control panel 1 includes an intake port 2 provided at one end and an exhaust port 3 provided at the other end. .
In the present embodiment, the humidity control panel 1 is applied to a vertical wall panel or a partition panel installed vertically on a wall surface or indoor space with the air inlet 2 at the lower end and the air outlet 3 at the upper end. An example is shown.

The size of the humidity control panel 1 can be set as appropriate according to the installation location or the like. However, when the vertical panel is installed as a wall panel or a partition panel as in the present embodiment, it is long. A vertically long and flat rectangular shape having a height (height) of about 1500 mm to 2000 mm, a width of about 200 mm to 500 mm, and a thickness of about 30 mm to 60 mm may be used. In the present embodiment, the humidity control panel 1 has a length (height) of about 1800 mm, a width of about 300 mm, and a thickness of about 45 mm.
The humidity control panel 1 includes a panel main body 9 that forms a vertically long middle portion, and an upper outer portion 30 and a lower outer portion 20 that are connected to the upper and lower portions of the panel main body 9, respectively.

The panel body 9 includes a front plate portion 9a on the front side of the panel, a back plate portion 9b on the back side of the panel, and a pair of side plate portions 9c and 9c (only one of them is shown in the figure) that connects these left and right. It is a hollow square cylindrical body configured.
The panel main body 9 composed of the front plate portion 9a, the back plate portion 9b, and the pair of side plate portions 9c, 9c may be formed integrally with a steel plate or the like. You may make it comprise.
In addition, a surface decorative material such as a decorative sheet, wallpaper, or veneer is attached to a portion exposed to the indoor space on the outer peripheral surface of the panel body 9 (in the case of a wall panel, the surface of the front plate portion 9a). It may be.

On the back surface side in the inner space of the panel body 9, a back surface air passage 5 constituting the first air passage is provided along the back plate portion 9 b, and the front surface side in the inner space of the panel body 9 is provided. The front side air passage 6 that constitutes the second air passage is provided along the front plate portion 9a.
In addition, a plate-like humidity-conditioning material holding layer 10 is provided between the rear side air passage 5 and the front side air passage 6 over the entire inner space of the panel body 9 in the vertical direction and the width direction. It has been.
That is, the inner space of the panel body 9 is divided by the humidity control material holding layer 10 provided in the substantially middle layer portion in the thickness direction, and the surface layer side space constitutes the surface side air passage 6, and the back layer side space. Constitutes the back air passage 5.
The ratio of the thickness dimension (thickness dimension along the thickness direction of the humidity control panel 1) of the front side air passage 6, the humidity control material holding layer 10 and the back side air passage 5 is 1: 2: 1 to 1. : It is good also as about 3: 1.

The humidity control material holding layer 10 opens on both sides in the thickness direction of the humidity control panel 1, and is multistage in the vertical direction of the panel main body 9 (the same direction as the blowing direction of both the air flow paths 5 and 6) and the width direction. A core material composed of an assembly of a large number of partitioned hollow cylindrical storage cells 11 is used as a core material, and the upper, lower, and both side portions of the outer periphery are the top plate portion, bottom plate portion, and both side plate portions of the panel body 9. It is fixed to 9c, 9c, etc.
The accommodation cell 11 is filled with a humidity control material 12 having moisture absorption / release properties.
In addition, film-like holding members 13 and 13 having air permeability and moisture permeability are respectively attached to the front surface side and the back surface side of the core material forming the accommodation cell 11.

  The core material for forming the storage cell 11 may be formed by stacking and adhering paper materials such as corrugated cardboard or kraft paper with an adhesive. Further, such a paper material may be further impregnated with a reinforcing resin such as an epoxy resin. In addition, it may be made of a metal material such as an aluminum material or a synthetic resin material such as a hard polyvinyl chloride resin or a polypropylene resin.

The cell shape of the accommodating cell 11 is a honeycomb-like honeycomb shape, a square shape, a rhombus shape, a cylindrical shape as defined in JIS A6931, a rib shape in which ribs are continuous in parallel, or a “<” shape. The origami shape may be a continuous origami shape.
The cell size (cell width) of the containing cell 11 may be about 10 mm to about 30 mm. In the present embodiment, the honeycomb-shaped accommodation cell 11 having a cell size of about 20 mm is made of a paperboard having a thickness of about 0.3 mm with little or no air permeability (non-breathable material).

The humidity control material 12 filled in the storage cell 11 is in the form of granular material, charcoal such as charcoal and bamboo charcoal, clay such as talc, zeolite, diatomaceous earth, silica gel (preferably B type), montmorillonite, sepiolite and the like. Examples thereof include inorganic substances such as minerals, alumina, and silica. Or it is good also as a polymer moisture absorption / release material which has a reversible moisture absorption function and a moisture release function. In the present embodiment, silica gel is used as the humidity control material 12.
The particle diameter of the humidity control material 12 may be about 1.0 mm to about 6.0 mm from the viewpoint of humidity control and air permeability. As the particle size of the humidity control material 12 decreases, the surface area of the humidity control material accommodated and filled per unit volume increases and the humidity control performance improves. However, the gap between the humidity control materials decreases and air permeability is hindered. On the other hand, as the particle size increases, the air permeability improves, but the humidity control property tends to be hindered. In the present embodiment, the humidity control material 12 having an average particle size of about 2.0 mm is employed.
In addition, you may use the said various humidity control materials 12 in combination of 2 or more types. Moreover, it is not restricted to a particulate-form humidity control material, It is good also as a flaky shape or a short fiber piece shape.

The film-like holding members 13 and 13 attached to the front side and the back side of the core material may be a cloth-like member or paper material having air permeability and moisture permeability. Alternatively, a net-like member obtained by processing a synthetic resin material or a metal material into a mesh shape so as to form a ventilation hole, or a sheet member having a large number of ventilation holes may be used.
The cloth-like member may be a cross sheet in which fibers are plain woven, one knitted by various woven forms, or a non-woven fabric.
Such a film-like holding member 13 may be configured to be able to hold the humidity adjusting material 12 without passing through, depending on the particle size of the humidity adjusting material 12 described above.

For example, the humidity control material holding layer 10 having the above-described configuration can be applied to each containing cell 11 from the other surface side of the core material after the one film-like holding member 13 is attached to the one surface side of the core material. Alternatively, the humidity adjusting material 12 may be filled, and the other film-like holding member 13 may be attached to the other side to form a plate shape. In this embodiment, the humidity control material holding layer 10 has a length (height) of about 1700 mm, a width of about 290 mm, a thickness of about 25 mm, and a total of about 6.0 kg of the humidity control material 12 in each containing cell. 11 is relatively densely packed.
By having such a large number of accommodating cells 11, the humidity control material holding layer 10 can be efficiently filled with the humidity control material 12. In particular, when the humidity control panel 1 is applied as a vertical panel installed so that the intake port 2 and the exhaust port 3 are positioned above and below as in the present embodiment, the weight of the humidity control material 12 is determined. The vertical deviation due to the

  The filling rate of the humidity control material 12 to each containing cell 11 may be filled densely as in the present embodiment, so that a gap of about 10% to 50% is formed in each containing cell 11. You may make it fill. Thus, if it fills so that a space | gap may be formed in each accommodation cell, the pressure loss of the air which passes the said humidity control material holding layer can be reduced, and the air permeability of a humidity control material holding layer Can be improved.

The lower outer portion 20 connected to the lower side of the panel main body 9 has a casing shape for housing the cross flow fan 4 constituting the air blowing means, and a plurality of slit-like intake ports 2 are formed on the surface side thereof. A plurality of lattice members 21 are provided.
An operation unit for performing the ON / OFF operation of the cross flow fan 4 or adjusting the air volume may be provided at an appropriate position of the front plate portion 9a of the panel body 9 described above. Further, a filter or the like for capturing dust or the like may be provided on the back side of the air inlet 2.
Near the back side of the top plate portion of the lower outer portion 20, the air inlet 2 and the back side air passage 5 of the panel body 9 are communicated to introduce air from the air inlet 2 into the back side air passage 5. An inlet 7 is provided.

The upper shell 30 connected to the upper side of the panel body 9 has an exhaust port 3 on the surface side. This exhaust port 3 is provided with a plurality of louvered louvers 31.
Close to the surface side of the bottom plate portion of the upper shell portion 30, the surface-side air passage 6 of the panel body 9 and the exhaust port 3 are communicated, and the air blown through the surface-side air passage 6 is sent to the upper shell portion 30. A lead-out port 8 that leads to the exhaust port 3 through the inner space is provided.
You may make it arrange | position the control part electrically connected with the crossflow fan 4 and its operation part in the inner space of this upper outer part 30. FIG. Further, the power supply to the cross flow fan 4, the control unit, the operation unit, and the like may be performed via a power cord (not shown) or the like that is appropriately drawn to the back side of the part. Moreover, you may make it provide the guide member which changes the airflow direction of the air ventilated toward the exhaust port 3 from the outlet port 8. FIG.

In the humidity control panel 1 configured as described above, indoor air is taken in from the air inlet 2 when the crossflow fan 4 is started by operating the operation unit.
The taken-in air is introduced into the back surface side air passage 5 through the introduction port 7 and passes through each accommodation cell 11 of the humidity control material holding layer 10 while being blown upward through the back surface side air passage 5. Then, the humidity is adjusted and led out to the front side air passage 6. The air led out to the front side air passage 6 is blown toward the outlet port 8 and is discharged from the exhaust port 3 toward the indoor space via the outlet port 8.

  As described above, according to the humidity control panel 1 according to the present embodiment, the air can be efficiently conditioned while circulating and stirring the indoor air. In particular, as in the present embodiment, if the air intake port 2 is at the lower end side and the air exhaust port 3 is at the upper end side and installed vertically on the wall surface or indoor space, it is positioned near the indoor floor surface. The air sucked from the lower intake port 2 can be discharged from the upper exhaust port 3 located near the ceiling of the room, so that the indoor air can be circulated and stirred more efficiently. The air can be conditioned more efficiently.

Moreover, since the air introduced into the back surface side air passage 5 from the air inlet 2 passes through the humidity control material holding layer 10 and is led to the front surface air passage 6, for example, the front side and the back surface of the panel internal space Compared with the case where the air flow path is provided only on one of the sides and the humidity control material holding layer is provided on the other side, the air can be efficiently brought into contact with the humidity control material 12, and the moisture absorption and desorption characteristics are improved. Can be improved.
In particular, in this embodiment, since each accommodation cell 11 of the humidity control material holding layer 10 is formed of a non-breathable material as described above, for example, when the accommodation cell is formed of a breathable material, Compared with the case where such an accommodation cell is not provided, the air introduced into the humidity control material holding layer 10 from the back surface side air passage 5 is directed in the vertical direction of the humidity control material holding layer 10 (both air passages 5, 6 along the same direction as the air blowing direction 6, can be reduced, passes substantially along the thickness direction, and is led to the surface side air passage 6. Thereby, while being able to improve ventilation efficiency, moisture absorption / release property can be improved more efficiently.
Moreover, since the air flow paths 5 and 6 are provided on the front surface side and the back surface side of the humidity control material holding layer 10, even when there is a temperature difference between the front and back of the humidity control panel 1, dew condensation in the panel internal space is caused. Occurrence can be prevented.

Next, another embodiment according to the present invention will be described with reference to the drawings.
FIG. 2 schematically shows the humidity control panel 1A according to the second embodiment, and is a diagram corresponding to FIG.
Note that differences from the first embodiment will be mainly described, and the same components are denoted by the same reference numerals, and description thereof will be omitted or simplified.
The humidity control panel 1A according to the present embodiment is mainly different from the humidity control panel 1 according to the first embodiment in the aspect of the humidity control material holding layer 10A and the aspect of the back surface side air passage 5A.

The humidity adjusting material holding layer 10A is formed so that the thickness dimension is gradually increased from the upstream side to the downstream side so that the back surface side air passage 5A is gradually narrowed from the upstream side to the downstream side. That is, the air path width (width along the panel thickness direction) of the back surface side air passage 5A is configured to decrease from the upstream side toward the downstream side.
In the present embodiment, as in the first embodiment, a core material made of an assembly of a large number of hollow cylindrical accommodation cells 11A that are partitioned in multiple stages in the vertical direction and the width direction of the panel body 9 is used as a core material. The thickness of the core is gradually increased from the upstream side toward the downstream side. As in the first embodiment, each accommodation cell 11A is filled with the humidity conditioning material 12 relatively densely.
In this embodiment, the humidity dimension holding layer 10A has a thickness of about 15 mm at the upstream end and about 35 mm at the downstream end.

In the humidity control panel 1 </ b> A configured as described above, a large pressure loss occurs in the rear side air passage 5 </ b> A itself narrowing on the downstream side, and a large pressure is also passed when passing through the humidity conditioning material holding layer 10 </ b> A having a large thickness dimension on the downstream side. Loss occurs, and the pressure loss on the downstream side increases dramatically.
As a result, the air introduced into the back surface side air passage 5A from the air inlet 2 is biased downstream and passes through the humidity control material holding layer when the air is blown through the back surface air passage 5A. Compared to the humidity control panel 1 according to the first embodiment, it can be greatly reduced. Therefore, the air blown through the back surface side air passage 5A is moderately dispersed and passes through the humidity control material holding layer 10A in the thickness direction. That is, in the present embodiment, the humidity-controlling material holding layer 10A whose thickness is increased from the upstream side toward the downstream side appropriately disperses the air blown through the back surface side air passage 5A and holds the humidity-controlling material. It functions as an airflow dispersion means for passing the layer 10A.
With such a configuration, according to the humidity control panel 1A according to the present embodiment, the thickness of each part along the blowing direction (vertical direction in the example) of the back surface side air passage 5A in the humidity control material holding layer 10A. The amount of air passing in the direction can be made uniform, and the indoor air can be more efficiently conditioned.

In the present embodiment, an example is shown in which the thickness dimension of the humidity control material holding layer is gradually increased from the upstream side toward the downstream side. It is good also as an aspect enlarged gradually in steps from the side toward a downstream side. Or it is good also as an aspect which combined these.
Further, in the present embodiment, the back surface side air passage is narrowed by the humidity conditioning material holding layer at the downstream end, and shows an aspect in which there is almost no air passage space, but is not limited to such an aspect, It is good also as an aspect which leaves ventilation path space in a downstream edge part.

Further, as in the present embodiment, as the airflow dispersion means, instead of the aspect of increasing the thickness dimension of the humidity conditioning material holding layer from the upstream side toward the downstream side, the thickness dimension of the humidity conditioning material holding layer is changed, Similar to the first embodiment, it has substantially the same thickness along the vertical direction, and the humidity control material holding layer is disposed to be inclined toward the back side, so that the back side air passage is arranged upstream. It is good also as an aspect narrowed toward the downstream side. Further, as the airflow dispersion means, instead of such a mode, the back plate portion of the panel body is inclined toward the front surface side so as to narrow the back surface side air passage from the upstream side toward the downstream side. Alternatively, such an inclined plate may be provided on the back plate portion.
Also according to these aspects, the pressure loss on the downstream side of the back surface side air passage can be positively increased as compared with the upstream side, and the effect substantially similar to that of the humidity control panel 1A according to the present embodiment can be obtained.

Next, still another embodiment according to the present invention will be described with reference to the drawings.
FIG. 3 is a view schematically showing a humidity control panel 1B according to the third embodiment and corresponding to FIG.
Note that differences from the first embodiment will be mainly described, and the same components are denoted by the same reference numerals, and description thereof will be omitted or simplified.
The humidity control panel 1B according to the present embodiment is mainly different from the humidity control panel 1 according to the first embodiment in the aspect of the back surface side air passage 5B.

In this embodiment, the baffle plates 14, 14,... That gradually narrow the back surface side air passage 5B from the upstream side toward the downstream side are spaced along the air blowing direction of the back surface air passage 5B. Provided.
In the present embodiment, these baffle plates 14 are provided at a plurality of locations (seven locations in the example) at predetermined intervals from the upstream end to the downstream end of the rear surface air passage 5B. The width dimension of the baffle plate 14 on the most upstream side (dimension along the panel thickness direction) is about 2.0 mm, and the width dimension of the baffle plate 14 on the most downstream side is about 8.0 mm. That is, the air path width (width along the panel thickness direction) of the back surface side air passage 5B in the portion where each baffle plate 14 is provided is configured to decrease from the upstream side toward the downstream side. The interval at which the baffle plate 14 is provided may be about 100 mm to 300 mm. Further, the length dimension (dimension along the panel width direction) of each baffle plate 14 is the length over the entire width direction of the inner space of the panel body 9.
Each of these baffle plates 14 may be fixed to the back surface side of the humidity control material holding layer 10 with an adhesive or the like, or may be fixed to both side plate portions 9c, 9c of the panel body 9. .

In the humidity control panel 1B configured as described above, the baffle plate 14 is narrowed by the baffle plate 14 so that the baffle plate 14 causes a large pressure loss on the upstream side and the downstream side. In addition to functioning as loss generating means, the baffle plate 14 also functions as airflow dispersing means for changing the airflow direction of a part of the air blown through the back-side air passage 5B to the humidity control material holding layer 10 side.
As a result, when the air introduced from the air inlet 2 into the back surface side air passage 5B is blown through the back surface side air passage 5B, the humidity control material is biased on the downstream side in the same manner as in the second embodiment. Things that pass through the layer can be reduced. Therefore, the air blown through the back surface side air passage 5B is moderately dispersed and passes through the humidity control material holding layer 10 in the thickness direction.
With such a configuration, according to the humidity control panel 1B according to the present embodiment, the thickness of each part along the air blowing direction (vertical direction in the example) of the back surface side air passage 5B in the humidity control material holding layer 10 is increased. The amount of air passing in the direction can be made uniform, and the indoor air can be more efficiently conditioned.

In the present embodiment, an example is shown in which a plurality of baffle plates are provided along the humidity control material holding layer side in the space of the rear air passage, but are provided along the back plate portion of the panel body. You may do it. Or you may make it provide in the approximate center part of the panel thickness direction in the space of a back surface side ventilation path.
Moreover, you may make it provide the baffle plate in this embodiment in the appropriate place of the back surface side ventilation path of the humidity control panel which concerns on the said 2nd Embodiment.

Next, still another embodiment according to the present invention will be described with reference to the drawings.
FIG. 4 is a view schematically showing a humidity control panel 1C according to the fourth embodiment and corresponding to FIG.
Note that differences from the first embodiment will be mainly described, and the same components are denoted by the same reference numerals, and description thereof will be omitted or simplified.
The humidity control panel 1C according to the present embodiment is mainly different from the humidity control panel 1 according to the first embodiment in the aspect of the humidity control material holding layer 10B.

The humidity control material holding layer 10 </ b> B has a configuration in which the particle size of the humidity control material accommodated and filled in each accommodation cell 11 is reduced from the upstream side toward the downstream side.
In this embodiment, four types of humidity control materials 12A, 12B, 12C, and 12D having different average particle diameters are used, and the humidity control material 12A on the most upstream side has an average particle diameter of about 5.0 mm. The humidity conditioning material 12B of about 3.0 mm, the humidity conditioning material 12C of about 2.0 mm, and the humidity conditioning material 12D of about 1.0 mm are accommodated and filled in this order toward the downstream side.

In the humidity control panel 1 </ b> C configured as described above, the upstream side of the humidity control material holding layer 10 </ b> B is filled with the humidity control material having a larger particle size than that of the downstream side. The air permeability becomes larger than that on the downstream side. In other words, on the downstream side of the humidity control material holding layer 10B, the humidity control material having a smaller particle diameter than that of the upstream side is filled, so the gap between the humidity control materials becomes smaller and the air permeability is higher than the upstream side. Becomes smaller. That is, the humidity-conditioning material holding layer 10B functions as a pressure loss generating unit that generates a large pressure loss on the upstream side and the downstream side, and the pressure loss on the downstream side increases dramatically.
As a result, when the air introduced into the back surface side air passage 5 from the air inlet 2 is blown through the back surface side air passage 5, it is biased on the downstream side in substantially the same manner as in the second and third embodiments. Thus, it is possible to reduce the passage through the humidity control material holding layer. Therefore, the air blown through the back surface side air passage 5 is moderately dispersed and passes through the humidity control material holding layer 10B in the thickness direction. That is, the air conditioning means is constituted by the humidity control materials 12 accommodated in the humidity control material holding layer 10B in the above-described manner.
With such a configuration, according to the humidity control panel 1 </ b> C according to the present embodiment, each part has a thickness along the air blowing direction (vertical direction in the illustrated example) of the back surface side air passage 5 in the humidity control material holding layer 10 </ b> B. The amount of air passing in the direction can be made uniform, and the indoor air can be more efficiently conditioned.

In this embodiment, four types of humidity control materials having different particle sizes are stored in the humidity control material holding layer. However, a plurality of types of humidity control materials having different particle sizes are arranged from the upstream side to the downstream side. In this case, the particles may be accommodated so that the particle diameter becomes smaller.
Further, in each humidity control panel according to the second embodiment and the third embodiment, the humidity control material accommodated in the humidity control material holding layer is changed in the particle size from the upstream side to the downstream side as in this embodiment. You may make it make small toward.

Further, although an example in which the intake port and the exhaust port constituting the pair of ventilation openings opened on the surface of the humidity control panel are separated from each other in the vertical direction is illustrated, they are formed to be separated from each other in the left and right directions. May be. That is, the humidity control panel may be installed horizontally as a horizontal panel.

Furthermore, in each of the above-described embodiments, an example in which a crossflow fan is provided in the lower outer portion as a blowing means for blowing air may be provided in the upper outer portion, or You may make it provide in the middle part of at least any one of the ventilation paths.
Moreover, it is not restricted to a cross flow fan, You may make it provide a sirocco fan, an axial flow fan, etc. as a ventilation means.
Furthermore, in each said embodiment, the example which provided the 1st ventilation path in which the air from an inlet port is introduce | transduced in the back surface side, and provided the 2nd ventilation path which ventilates air toward an exhaust port in the surface side is shown. However, each may be provided on the opposite side.

Furthermore, while providing the partition plate which divides | segments the surface side ventilation path of the humidity control panel which concerns on this embodiment, a humidity control material holding | maintenance layer, a back surface side ventilation path, an up-and-down outer part, etc. in a panel width direction, It is good also as an aspect which provides the ventilation means which can be driven independently, uses one side as above lower intake and upper exhaust, and uses the other as upper intake and lower exhaust. According to this, the temperature difference of the indoor space can be efficiently reduced by driving any of the air blowing means according to the temperature distribution in the indoor space.
Further, in the present embodiment, the humidity control material holding layer has a number of hollow cylindrical storage cells that are divided into multiple stages in the vertical direction and the width direction of the panel body, respectively. Although the example which filled the material is shown, it is good also as what consists of many accommodation cells divided in multiple steps only in the up-down direction (the same direction as the ventilation direction of each ventilation path). Or it is good also as an aspect which comprises a plate-shaped humidity-conditioning material holding | maintenance layer, without providing such many accommodation cells.
