The first outlet 14 a is disposed on the other side S <b> 2 with respect to the stud 6. Thereby, the 1st extraction opening 14a and the air flow path 15 (2nd space 5B) can be connected. Although the 1st taking-out port 14a of this embodiment is formed circularly in planar view similarly to the 1st taking-in port 13a, it is not necessarily limited to such an aspect.

  Similarly to the second intake port 13b, the second intake port 14b of the present embodiment is configured such that the room side surface material 4s, the moisture-proof layer 9, the heat insulating material 10, and the humidity control means 16 are arranged on the upper side of the room side surface material 4s. 2 in the thickness direction. The second outlet 14b is disposed on the other side S2 with respect to the stud 6. Thereby, the 2nd outlet 14b and the air flow path 15 (2nd space 5B) can be connected. The second outlet 14b of the present embodiment is formed in a horizontally long rectangular shape in a front view like the second inlet 13b, but is not limited to such a mode.

  As shown in FIG. 3, the air flow path 15 of the present embodiment includes the first space 5A, the second space 5B, and the communication portion 7 that connects the first space 5A and the second space 5B. Yes. Thereby, the air flow path 15 extends the inside of the panel in a substantially U shape in a front view.

Furthermore, the upper side of the second space 5 </ b> B is the other end side of the air flow path 15.

  As shown in FIG. 3, one end side of the air flow path 15 (that is, the upper side of the first space 5A) is the air intake port 13 (in this embodiment, the first intake port 13a and the second intake port). It communicates with the mouth 13b). Thereby, external air can be taken into the air flow path 15 via the air intake port 13.

  The other end side of the air flow path 15 (that is, the upper side of the second space 5B) communicates with the air outlet 14 (in this embodiment, the first outlet 14a and the second outlet 14b). Thereby, the air Ac in the air flow path 15 can be discharged to the outside of the panel 2 through the air outlet 14.

  As shown in FIGS. 2 and 4, the humidity control means 16 has a humidity control function that absorbs moisture (absorbs moisture) and releases moisture (moisture release) according to the amount of moisture contained in the air. I have it. The humidity control means 16 is disposed at least at a part of the position facing the air flow path 15 inside the panel. For example, when high-humidity air is taken into the air flow path 15, moisture contained in the air can be absorbed by the humidity adjusting means 16. Further, when low-humidity air is taken into the air flow path 15, the moisture absorbed by the humidity control means 16 can be released into the low-humidity air.

  The humidity control means 16 of the present embodiment is configured as a pair of humidity control boards 16a and 16a arranged along the insides of the face materials 4 and 4, respectively. Each humidity control board 16a, 16a is formed in a plate shape having a rectangular shape in plan view, for example, and is disposed in the entire area inside each face material 4, 4. The humidity control boards 16 a and 16 a of the present embodiment are disposed on the innermost side in the thickness direction of the panel 2 through the moisture-proof layers 9 and 9 and the heat insulating materials 10 and 10. Further, the pair of humidity control boards 16 a and 16 a are separated from each other in the thickness direction of the panel 2. Thereby, as for the panel 2 of this embodiment, the air flow path 15 is formed of the clearance gap between the humidity control boards 16a and 16a. Since the humidity control means 16 is disposed over the entire area of the air flow path 15 by such a pair of humidity control boards 16a, 16a, the humidity control function can be effectively exhibited.

The humidity control means 16 (humidity control board 16a) preferably has a moisture absorption / release amount of 100 g / m ² or more and a moisture absorption rate of 15 g / m ² · h or more when the relative humidity is 10% RH to 70% RH. Such humidity control means 16 can effectively exhibit the humidity control function.

  It is desirable that the humidity adjusting means 16 (humidity adjusting board 16a) includes a humidity adjusting material capable of maintaining the moisture absorption / release amount and the moisture absorption speed. It is desirable that at least the surface of the humidity control material has a porous structure. The humidity control material having such a porous structure can effectively exhibit the humidity control function.

  As the humidity conditioner, for example, diatomaceous earth, siliceous shale, allophane, imogolite, acid clay, zeolite, calcium silicate, silica gel, bentonite, montmorillonite, or charcoal can be employed. The humidity control board 16a may be formed using any one of these humidity control materials, or the humidity control board 16a may be formed by combining these humidity control materials. The humidity control board 16a preferably contains 20 to 95% by weight of a humidity control material.

  As shown in FIG. 2, the panel 2 of the present embodiment is configured such that, for example, when high-humidity air is taken in from the air intake port 13 (the first intake port 13a or the second intake port 13b), Moisture contained in the air is absorbed by the humidity control means 16 disposed in the path 15. The low-humidity air in which moisture has been absorbed is taken out from the air outlet 14 (the first outlet 14a or the second outlet 14b). For example, when high-humidity air in the living room L is supplied to the humidity control unit 16 and low-humidity air absorbed by the humidity control unit 16 is supplied to the living room L, the room L can be dehumidified. .

  When low-humidity air is taken in from the air intake port (the first intake port 13a or the second intake port 13b), the moisture absorbed by the humidity control means 16 is released into the air. Highly humid air from which moisture has been released from the humidity control means 16 is taken out from the air outlet 14 (the first outlet 14a or the second outlet 14b). For example, when the low-humidity air in the living room L is supplied to the humidity control means 16 and the high-humidity air released from the humidity control means 16 is supplied to the living room L, the living room L can be humidified. .

  Thus, unlike the conventional humidity control panel (not shown) arranged facing the living room L, the panel 2 of the present embodiment actively circulates air in the air flow path 15 inside the panel. Therefore, the air in the living room L can be effectively conditioned. Moreover, the humidity adjustment means 16 of the present embodiment can adjust the moisture absorption amount and moisture release amount by appropriately supplying and stopping air to the air flow path 15. Therefore, the panel 2 of the present embodiment can effectively adjust the air without depending on the indoor environment of the living room L.

As shown in FIG. 4, in the present embodiment, since the moisture-proof layer 9 is arranged inside the face material 4, the moisture absorbed by the humidity adjusting means 16 is passed through the face material 4 to the living room L. It can be prevented from being released to the like. Therefore, a decrease in the equilibrium moisture content of the humidity control means 16 can be suppressed, and the humidity control function can be effectively exhibited. In order to effectively exhibit such an action, the moisture permeation resistance of the moisture-proof layer 9 is desirably 0.0175 m ² · s · Pa / ng or more.

  As shown in FIG. 3, in the present embodiment, the air intake port 13 and the air intake port 14 are opposite to the direction in which the communication portion 7 of the stud 6 is provided (the lower side in the present embodiment). (In this embodiment, it is provided on the upper side). Thereby, for example, compared with the case where the air intake port 13, the air intake port 14 and the communication portion 7 are provided in the same direction, or when the air intake port 13 and the air intake port 14 are provided in the opposite direction, The length of the air flow path 15 from the air intake port 13 to the air intake port 14 can be increased. Therefore, since the surface area of the humidity control means that comes into contact with the air supplied to the air flow path 15 can be increased, the humidity of the air can be effectively adjusted.

  FIG. 5 is a graph showing the relationship between the relative humidity of air and the equilibrium moisture content of the humidity control means. The humidity control means shown in this graph has good moisture absorption / release performance in a relative humidity range of approximately 30% RH to 70% RH. As shown in the graph of FIG. 5, for example, in winter, outdoor air (low temperature air) has a higher relative humidity than room air (high temperature air). Such outdoor air having a high relative humidity can increase the equilibrium moisture content of the humidity control means 16 (shown in FIG. 4) as compared to the air in a room having a low relative humidity. Therefore, in order to make the humidity control means 16 absorb moisture effectively, it is desirable that outdoor air having a high relative humidity is supplied to the humidity control means 16 (shown in FIG. 4).

  In addition, the air in the room with a low relative humidity can lower the equilibrium moisture content of the humidity control means 16 (shown in FIG. 4) than the outdoor air with a high relative humidity. Therefore, in order to effectively release moisture to the humidity control means 16, it is desirable that the air in the room having a low relative humidity is supplied to the humidity control means 16 (shown in FIG. 4).

  In order to effectively absorb and dehumidify the humidity control means 16 using such outdoor air and room air, the panel 2 of the present embodiment has, for example, an intake as shown in FIG. Further included are a take-in duct 21, a first take-in damper 22, a take-out duct 23, a first take-out damper 24, a second take-in damper 25 and a second take-out damper 26.

  As shown in FIG. 2, the intake duct 21 is formed in a cylindrical shape that is continuous from one end to the other end, for example. As shown in FIG. 1, one end of the intake duct 21 is connected to the first intake port 13a. The other end of the intake duct 21 is connected to the hut 30 of the building B. By such a duct 21, the cabin back 30 (shown in FIG. 1) and the air flow path 15 (first space 5A) can be communicated with each other via the first intake port 13a.

  The air behind the hut (outdoor air) Ao has a lower relative humidity than, for example, air Ai in the room or air (not shown) air-conditioned (heated) by an air conditioner, and therefore has a high relative humidity. By supplying the air Ao in the back of the hut to the humidity control means 16 (shown in FIG. 4) disposed in the air flow path 15 through the intake duct 21 and the first intake port 13a. The moisture contained in the air Ao in the shed can be effectively absorbed by the humidity control means 16.

  As shown in FIG. 1, the intake duct 21 of the present embodiment is provided with a fan 29 that blows air from the cabin back 30 side toward the panel 2 side. By operating such a fan 29, the cabin 30 can be negatively pressured, and the cabin air (outdoor air) Ao can be actively supplied to the humidity control means 16.

  The air Ao behind the cabin supplied to the air flow path 15 is supplied from the first space 5A to the second space 5B via the communication portion 7. Therefore, as shown in FIG. 3, the air Ao (shown in FIG. 2) in the back of the hut can be circulated from one end side to the other end side of the air flow path 15. Moisture contained in the air Ao at the back of the hut can be absorbed uniformly by the humidity control means 16 thus made. Note that the operation / stop of the fan 29 is preferably performed by, for example, control means or a resident's operation.

As shown in FIG. 4, in this embodiment, the heat insulating material 10 is arranged between the face material 4 and the humidity control board 16 a. For this reason, it is possible to prevent the air behind the hut (outdoor air) Ao supplied to the air flow path 15 from being warmed by the air Ai in the living room. Accordingly, it is possible to suppress a decrease in the relative humidity of the air Ao behind the hut supplied to the air flow path 15 and to prevent a decrease in the moisture absorption rate to the humidity control means 16. In order to effectively exhibit such an action, the thermal resistance of the heat insulating material 10 is desirably 0.2 m ² K / W or more.

  As shown in FIG. 1, in the present embodiment, the aspect in which the other end of the intake duct 21 is connected to the cabin back 30 is exemplified, but the embodiment is not limited thereto. For example, the other end of the intake duct 21 may be connected to the outdoor So of the building B. In winter, the outdoor So air has a higher relative humidity than the air in the room, similar to the air behind the cabin. When such outdoor So air (outdoor air) is supplied to the air flow path 15 shown in FIG. 3, the moisture contained in the outdoor So air is adjusted to humidity control means 16 (shown in FIG. 4). Can be effectively absorbed.

  As shown in FIG. 1, the first intake damper 22 is for opening and closing the other end side of the intake duct 21. For example, when the first intake damper 22 is opened, the air Ao behind the cabin can be supplied to the air flow path 15 as shown in FIG. Further, by closing the first intake damper 22 (shown in FIG. 1), it is possible to prevent the air Ai in the room from flowing out to the cabin 30 due to natural ventilation in winter, for example. The opening and closing of the first intake damper 22 is preferably performed by, for example, control means or a resident's operation.

  As shown in FIG. 2, the take-out duct 23 is formed in a cylindrical shape, like the take-in duct 21. As shown in FIG. 1, one end of the take-out duct 23 is connected to the first take-out port 14a. The other end of the take-out duct 23 is connected to the shed 30 of the building. By such an extraction duct 23, the air flow path 15 (second space 5B) and the cabin back 30 shown in FIG. 2 can be communicated with each other via the first outlet 14a. Thereby, as shown in FIG. 2, the air Ac circulated through the air flow path 15 can be directly discharged to the back of the hut 30 (shown in FIG. 1). For example, when the outdoor air Ao absorbed by the humidity control means 16 is discharged to the back of the hut 30, it is possible to prevent the low temperature outdoor air Ao from being supplied to the living room L, so that the temperature of the living room L decreases. Can be prevented.

  In the present embodiment, the mode in which the other end of the take-out duct 23 is connected to the cabin back 30 is exemplified, but the present invention is not limited to this. For example, the other end of the take-out duct 23 may be connected to the outdoor So of the building B (shown in FIG. 1).

  As shown in FIG. 1, the first extraction damper 24 is for opening and closing the other end side of the extraction duct 23. For example, when the first extraction damper 24 is opened, the air Ac circulated through the air flow path 15 can be discharged to the cabin 30. Further, by closing the first take-off damper 24, it is possible to prevent the air Ai in the room from flowing out into the cabin 30 by natural ventilation in winter, for example. The opening and closing of the first take-off damper 24 is preferably performed by, for example, control means or a resident's operation.

  As shown in FIG. 2, the second intake damper 25 is for opening and closing the second intake port 13b. For example, the air Ai in the living room can be supplied to the air flow path 15 (shown in FIG. 3) by opening the second intake damper 25. Since the air Ai in the room is higher in temperature than the air (outdoor air) Ao in the back of the hut, the relative humidity is low. By supplying the air Ai in the living room to the humidity control means 16 disposed in the air flow path 15, moisture absorbed by the humidity control means 16 is released to obtain high-humidity air. Can do.

  The opening and closing of the second intake damper 25 is preferably performed by, for example, control means (not shown) or a resident's operation. The second intake port 13b is preferably provided with a fan (not shown) that blows air from the living room L side toward the air flow path 15 side. By operating the fan with the second intake damper 25 opened, the air Ai in the room can be effectively circulated through the air flow path 15.

  The 2nd extraction damper 26 is for opening and closing the 2nd extraction opening 14b. For example, the air Ac circulated through the air flow path 15 can be supplied to the living room L by opening the second extraction damper 26. For example, when the air Ai in the room whose relative humidity has been increased by releasing moisture from the humidity control means 16 is supplied to the room L, the room L can be humidified effectively. Note that the opening and closing of the second take-out damper 26 is preferably performed by, for example, control means or a resident's operation.

  Next, a humidity control system that adjusts the humidity of the living room L using the panel 2 of the present embodiment will be described. The humidity control system of the present embodiment includes a first air flow path and a second air flow path. FIG. 6 is a conceptual diagram illustrating the first air flow path 15A of the humidity control system of the present embodiment.

  The first air flow path 15A is for supplying the humidity adjusting means 16 (shown in FIG. 4) with the first air A1 having a high relative humidity so that the humidity adjusting means 16 absorbs moisture. The first air A1 of the present embodiment is outdoor air (air behind the hut) Ao that is cooler than the air Ai (shown in FIG. 4) in the living room.

  In the present embodiment, the first intake damper 22 and the first extraction damper 24 are opened, and the second intake damper 25 and the second extraction damper 26 are closed. As a result, the first air flow path 15 </ b> A from the cabin back 30 to the cabin back 30 through the first space 5 </ b> A and the second space 5 </ b> B of the panel 2 is set. Accordingly, at least a part of the first air flow path 15A of the present embodiment is formed by a gap between the humidity control boards 16a and 16a (shown in FIG. 4), and the inside of the panel 2 facing the living room L. It has been extended.

  In the present embodiment, the fan 29 of the intake duct 21 is operated. By such a first air flow path 15 </ b> A, the air behind the hut (outdoor air) Ao is supplied to humidity control means 16 (shown in FIG. 4) disposed inside the panel 2.

  As shown in FIG. 5, the air Ao in the hut is higher in relative humidity than the air in the room L in winter. For this reason, the moisture contained in the air (outdoor air) Ao in the back of the hut can be effectively absorbed by the humidity control means 16 (shown in FIG. 4). As described above, the first air flow path 15A of the present embodiment circulates the first air A1 having high relative humidity (in the present embodiment, outdoor air Ao) and effectively absorbs moisture by the humidity adjusting means 16. Can do.

  As shown in FIG. 6, the air Ac circulated through the first air flow path 15A (in this embodiment, the air behind the hut (outdoor air) Ao in which moisture has been absorbed by the humidity control means 16) is the first intake. It is discharged directly to the cabin 30 via the outlet 14a and the extraction duct 23. Therefore, since the outdoor air Ao is not supplied to the living room L, the first air flow path 15A of this embodiment can prevent a temperature drop of the living room L.

  FIG. 7 is a conceptual diagram illustrating the second air flow path 15B of the humidity control system of the present embodiment. The second air flow path 15B is for supplying the second air A2 having a low relative humidity to the moisture adjusting means 16 (shown in FIG. 4) that has absorbed moisture to obtain the third air A3 having an increased relative humidity. is there. The second air A2 in the present embodiment is the air Ai in the living room that is hotter than the outdoor air (in this embodiment, air behind the hut) Ao (shown in FIG. 6).

  In the present embodiment, the second intake damper 25 and the second extraction damper 26 are opened, and the first intake damper 22 and the first extraction damper 24 are closed. Further, the fan 29 of the intake duct 21 is stopped. Thereby, the second air flow path 15B from the living room L to the living room L through the first space 5A and the second space 5B of the panel 2 is set. Accordingly, at least a part of the second air flow path 15b of the present embodiment is formed by a gap between the humidity control boards 16a and 16a (shown in FIG. 4), and in the panel 2 facing the living room L. It has been extended. Due to the second air flow path 15b, the high-temperature air Ai in the room is humidity adjusting means arranged inside the panel 2 by a fan or the like (not shown) provided in the second intake damper 25, for example. 16 (shown in FIG. 4).

  As shown in FIG. 5, in the winter season, the air Ai in the room has a lower relative humidity than the air Ao in the back of the hut. For this reason, the water | moisture content contained in the humidity control means 16 (shown in FIG. 4) can be discharge | released effectively in the air Ai of the living room which circulates through the 2nd air flow path 15B. Therefore, as shown in FIG. 7, the second air flow path 15B of the present embodiment releases the humidity control means 16 (shown in FIG. 4) that has absorbed moisture by the first air flow path 15A (shown in FIG. 6). It is possible to obtain the third air A3 that has been wetted to increase the relative humidity.

  The third air A3 with increased relative humidity is supplied to the living room L via the second outlet 14b. Therefore, the second air flow path 15B of the present embodiment is supplied with the highly humid third air A3 to the living room L where the humidity tends to decrease due to air conditioning (heating) of an air conditioner or the like (not shown), for example. Therefore, the living room L can be humidified effectively.

  As described above, the humidity control system of the present embodiment has the first air flow path 15A (shown in FIG. 6) that actively absorbs moisture by the humidity control means 16 (shown in FIG. 4) and the third air humidity that is increased in relative humidity. The living room L can be humidified by the second air flow path 15B (shown in FIG. 7) that obtains the air A3. Therefore, the humidity control system can adjust the humidity of the living room L without depending on the indoor environment of the living room L.

  In the humidity control system of the present embodiment, the first air flow path 15A shown in FIG. 6 is desirably set when there is no resident in the living room L. Thereby, it is possible to concentrate moisture on the humidity control means 16 without taking into consideration humidification of the living room L. Furthermore, the second air flow path 15B shown in FIG. 7 is desirably set when a resident is staying in the living room L. Thereby, the living room L can be concentrated and humidified using the moisture stored in the humidity control means 16. Thus, the humidity control system of the present embodiment can control the humidity of the living room L in accordance with the living rhythm of the resident. In addition, since the panel 2 of this embodiment is provided in the bedroom Ls, indoor drying which tends to occur when the resident sleeps can be effectively prevented.

  The switching of the first air flow path 15A and the second air flow path 15B is preferably switched by a control means (not shown) provided in the building B, a resident's operation, or the like. Further, it is desirable to determine whether or not the living room L is staying with a sensor provided in the living room L or a predetermined timer.

  FIG. 8 is a conceptual diagram of a building B in which a panel according to another embodiment of the present invention is used. In addition, in this embodiment, about the same structure as previous embodiment, the same code | symbol may be attached | subjected and description may be abbreviate | omitted.

  The building B of this embodiment includes an air conditioner 31 provided in the underfloor space 35 and a duct 36 that connects the air conditioner 31 and each living room L. Further, the duct 36 is provided with a fan 37 that blows air from the air conditioner 31 toward each room L. By operating the air conditioner 31 and the fan 37, high-temperature air-conditioned (heated) air Aw can be supplied to each living room L.

  FIG. 9 is a graph showing the relationship between the relative humidity of air and the equilibrium moisture content of the humidity control means. The humidity control means shown in this graph has good moisture absorption / release performance in a relative humidity range of approximately 10% RH to 30% RH. As shown in the graph of FIG. 9, for example, in winter, air in a room (low-temperature air) has a higher relative humidity than air that has been air-conditioned (heated) at a high temperature. The air in such a room can increase the equilibrium moisture content of the humidity control means 16 (shown in FIG. 4) compared to high-temperature air-conditioned air. Therefore, in order to cause the humidity control means 16 to absorb moisture effectively, it is desirable that the air in the room having a high relative humidity is supplied to the humidity control means 16 (shown in FIG. 4).

  Moreover, the high-temperature air-conditioned air can lower the equilibrium moisture content of the humidity control means 16 (shown in FIG. 4) compared to the air in the room. Therefore, in order to effectively release moisture to the humidity control means 16, it is desirable that high-temperature conditioned air having a low relative humidity is supplied to the humidity control means 16 (shown in FIG. 4).

  Based on such a viewpoint, the panel 2 of this embodiment uses the air in the living room to absorb the moisture in the humidity adjusting means 16 and uses the high-temperature conditioned air to adjust the humidity adjusting means 16 (FIG. 4). (Shown in the above). FIG. 10 is a front view of a panel according to another embodiment of the present invention. In addition, in this embodiment, about the same structure as previous embodiment, the same code | symbol may be attached | subjected and description may be abbreviate | omitted.

It is included. In addition, the panel 2 of this embodiment includes the intake duct 21, the first intake damper 22, the first intake outlet 14a, the extraction duct 23, and the first extraction damper 24 of the previous embodiment shown in FIG. Not included.

  As with the panel 2 of the previous embodiment, the second intake damper 25 opens and closes the second intake port 13b, and humidity control means 16 (see FIG. 4). The air Ai in the living room has a higher relative humidity than the air Aw that has been air-conditioned (heated) at a high temperature. The air Ai in the living room having such a high relative humidity is supplied to the humidity control means 16 (shown in FIG. 4) disposed in the air flow path 15, so that the moisture contained in the air Ai in the living room is The moisture conditioning means 16 can effectively absorb the moisture.

  As with the intake duct 21 (shown in FIG. 2), the air conditioning duct 32 is formed in a cylindrical shape that continues from one end to the other end. One end of the air conditioning duct 32 is connected to the first intake port 13a. The other end of the air conditioning duct 32 is connected to a duct 36 to which the air conditioner 31 is connected. By such an air conditioning duct 32, the air conditioner 31 and the air flow path 15 (first space 5A) can be communicated via the first intake port 13a.

  High-temperature air-conditioned (heated) air Aw has a lower relative humidity than air Ai in the room. Such high-temperature conditioned air Aw having a low relative humidity is supplied to the humidity control means 16 (shown in FIG. 4) disposed in the air flow path 15 and absorbed by the humidity control means 16. Moisture can be released to obtain highly humid air.

  The third intake damper 33 is for opening and closing the other end side of the air conditioning duct 32. For example, the humidity control means 16 (shown in FIG. 4) in which the air Aw air-conditioned (heated) to a high temperature by the air conditioner 31 by opening the third intake damper 33 is disposed in the air flow path 15. Can be supplied. By closing the third intake damper 33, it is possible to prevent high-temperature air-conditioned (heated) air Aw from being supplied to the air flow path 15. The opening and closing of the third intake damper 33 is preferably performed by, for example, control means or a resident's operation.

  Next, a humidity control system that adjusts the humidity of the living room L using the panel 2 of this embodiment will be described. The humidity control system of this embodiment includes a first air flow path 15A and a second air flow path 15B. FIG. 11 is a conceptual diagram illustrating a first air flow path 15A according to another embodiment of the present invention.

  The first air flow path 15A of this embodiment supplies the first air A1 having a high relative humidity to the humidity control means 16 (shown in FIG. 4), similarly to the first air flow path 15A of the previous embodiment. This is for causing the humidity control means 16 to absorb moisture. The first air A1 of the present embodiment is the air Ai in the living room that is cooler than the hot air-conditioned air Aw.

  In this embodiment, the second intake damper 25 and the second extraction damper 26 are opened, and the third intake damper 33 is closed. Thereby, the first air flow path 15A from the living room L to the living room L through the first space 5A and the second space 5B of the panel 2 is set. Accordingly, at least a part of the first air flow path 15A of the present embodiment is formed by a gap between the humidity control boards 16a and 16a (shown in FIG. 4), and the inside of the panel 2 facing the living room L. It has been extended. The air Ai in the living room is supplied to the humidity control means 16 (shown in FIG. 4) disposed inside the panel 2 by the first air flow path 15A.

  The air Ai in the room has a higher relative humidity than the high-temperature air-conditioned air Aw. For this reason, the water | moisture content contained in the air Ai of a living room can be effectively absorbed into the humidity control means 16 (shown in FIG. 4). In this way, the first air flow path 15A of this embodiment circulates the first air A1 having a high relative humidity (in this embodiment, the air Ai in the room) and effectively absorbs moisture by the humidity adjusting means 16. be able to.

  The air Ac circulated through the first air flow path 15 </ b> A (in this embodiment, the air Ai in the room in which moisture has been absorbed by the humidity control means 16) is discharged to the room L via the second extraction damper 26. Thereby, since it can prevent that the living room L becomes negative pressure, it can prevent that cold air permeates from the clearance gap between the living rooms L. FIG.

  FIG. 12 is a conceptual diagram illustrating a second air flow path 15B according to another embodiment of the present invention. Similarly to the second air flow path 15B (shown in FIG. 7) of the previous embodiment, the second air flow path 15B of this embodiment allows the humidity adjusting means 16 (shown in FIG. 4) to absorb relative humidity. This is to obtain the third air A3 by supplying the low second air A2 and increasing the relative humidity. The second air A2 in this embodiment is air Aw that has been air-conditioned at a higher temperature than the air Ai in the living room.

  In this embodiment, the third intake damper 33 and the second extraction damper 26 are opened, and the second intake damper 25 is closed. Thereby, the 2nd air flow path 15B which reaches the living room L through the 1st space 5A and the 2nd space 5B of the panel 2 from the air conditioner 31 (duct 36) is set. Therefore, at least a part of the second air flow path 15B of the present embodiment is formed by a gap between the humidity control boards 16a and 16a (shown in FIG. 4), and in the panel 2 facing the living room L. It has been extended. By such a second air flow path 15B, the high-temperature air-conditioned air Aw is supplied to the humidity control means 16 (shown in FIG. 4) disposed inside the panel 2.

  The high-temperature air-conditioned air Aw has a lower relative humidity than the air Ai in the room. For this reason, the water | moisture content contained in the humidity control means 16 can be discharge | released effectively in the high temperature air-conditioned air Aw which circulates through the 2nd air flow path 15B. Accordingly, the second air flow path 15B of this embodiment increases the relative humidity by dehumidifying the humidity adjusting means 16 (shown in FIG. 4) that has absorbed moisture by the first air flow path 15A (shown in FIG. 11). The third air A3 can be obtained.

  The 3rd air A3 which raised the relative humidity is discharged | emitted by the living room L through the 2nd outlet 14b. Thus, since the 2nd air flow path 15B of this embodiment can supply the high temperature and high humidity 3rd air A3 to the living room L, it can make the heating and humidification of the living room L compatible.

  FIG. 13 is a conceptual diagram of a building B in which a panel according to still another embodiment of the present invention is used. In addition, about the same structure as embodiment so far, the same code | symbol may be attached | subjected and description may be abbreviate | omitted. The building B of this embodiment includes an air conditioner 31 and a duct 36 as in the building B of the previous embodiment (shown in FIG. 8). For this reason, each living room L can be supplied with high-temperature air-conditioned (heated) air Aw.

  FIG. 14 is a graph showing the relationship between the relative humidity of air and the equilibrium moisture content of the humidity control means. The humidity control means shown in this graph has good moisture absorption / release performance in a relative humidity range of approximately 10% RH to 70% RH. As shown in the graph of FIG. 14, for example, in winter, outdoor air (low-temperature air) has a higher relative humidity than hot air-conditioned air. Such outdoor air can increase the equilibrium moisture content of the humidity control means 16 (shown in FIG. 4) compared to high-temperature conditioned air. Therefore, in order to make the humidity control means 16 absorb moisture effectively, it is desirable that outdoor air having a high relative humidity is supplied to the humidity control means 16 (shown in FIG. 4).

  Moreover, the high-temperature air-conditioned air can lower the equilibrium moisture content of the humidity control means 16 (shown in FIG. 4) compared to the outdoor air. Therefore, in order to effectively release moisture to the humidity control means 16, it is desirable that high-temperature conditioned air having a low relative humidity is supplied to the humidity control means 16 (shown in FIG. 4).

  Based on such a point of view, the panel 2 of this embodiment uses the outdoor air to cause the humidity adjusting means 16 to absorb moisture, and uses high-temperature conditioned air to release the moisture to the humidity adjusting means 16. ing. FIG. 15 is a front view of a panel according to still another embodiment of the present invention. In addition, about the same structure as embodiment so far, the same code | symbol may be attached | subjected and description may be abbreviate | omitted.

  As shown in FIGS. 13 and 15, the panel 2 of this embodiment includes the intake duct 21, the first intake damper 22, the extraction duct 23, the first extraction damper 24, and the second extraction of the previous embodiments. In addition to the damper 26, the air conditioning duct 32 and the third intake damper 33, a connection duct 41 is further included. Note that the panel 2 of this embodiment does not include the second intake damper 25 (shown in FIG. 10).

  The connection duct 41 is for connecting the first intake port 13 a, the intake duct 21, and the air conditioning duct 32. As shown in FIG. 15, the connecting duct 41 is connected to the main pipe 41 </ b> A connected to the first intake port 13 a, the first branch pipe 41 </ b> B connected to one end of the intake duct 21, and one end of the air conditioning duct 32. A second branch pipe 41C to be connected is included. By such a connecting duct 41, between the cabin 30 (shown in FIG. 14) and the air flow path 15 (first space 5A), and the air conditioner 31 (air conditioning duct 32) and the air flow path 15 (first 1 space 5A) can be communicated.

  Next, a humidity control system that adjusts the humidity of the living room L using the panel 2 of this embodiment will be described. The humidity control system of the present embodiment includes a first air flow path 15A and a second air flow path 15B. FIG. 16 is a conceptual diagram illustrating a first air flow path 15A according to still another embodiment of the present invention.

  The first air flow path 15A of this embodiment is similar to the first air flow path 15A (illustrated in FIGS. 6 and 11) of the previous embodiments. Is supplied to the humidity control means 16 to absorb moisture. The first air A1 of the present embodiment is outdoor air (air behind the hut) Ao that is cooler than the hot air-conditioned air Aw.

  In this embodiment, the 1st taking-in damper 22 and the 1st taking-out damper 24 are opened, and the 2nd taking-out damper 26 and the 3rd taking-in damper 33 are closed. As a result, the first air flow path 15 </ b> A from the cabin back 30 to the cabin back 30 through the first space 5 </ b> A and the second space 5 </ b> B of the panel 2 is set. Accordingly, at least a part of the first air flow path 15A of the present embodiment is formed by a gap between the humidity control boards 16a and 16a (shown in FIG. 4), and the inside of the panel 2 facing the living room L. It has been extended. Further, the fan 29 of the intake duct 21 is operated. By such a first air flow path 15 </ b> A, low-temperature air in the cabin (outdoor air) Ao is supplied to the humidity control means 16 disposed inside the panel 2.

  In winter, the air in the shed Ao has a higher relative humidity than the hot air-conditioned air Aw. For this reason, the water | moisture content contained in the air Ao of a hut can be effectively absorbed into the humidity control means 16 (shown in FIG. 4). Thus, the first air flow path 15A of this embodiment circulates the first air A1 having high relative humidity (in this embodiment, the outdoor air Ao), and effectively absorbs moisture by the humidity adjusting means 16. Can do.

  The air Ac that circulates through the first air flow path 15A (in this embodiment, the low-temperature air Ao that has been absorbed by the humidity control means 16) passes through the first outlet 14a and the extraction duct 23. Since it is discharged to the back of the hut 30, the temperature drop of the living room L can be prevented.

  FIG. 17 is a conceptual diagram illustrating a second air flow path 15B according to another embodiment of the present invention. The second air flow path 15B of this embodiment has a low relative humidity to the humidity adjusting means 16 that has absorbed moisture, as in the second air flow path 15B of the previous embodiments (shown in FIGS. 7 and 12). The second air A2 is supplied to obtain the third air A3 having an increased relative humidity. The second air A2 in this embodiment is the air-conditioned air Aw that is hotter than the air Ai in the room and the air Ao in the room.

  In this embodiment, the third intake damper 33 and the second extraction damper 26 are opened, and the first intake damper 22 and the first extraction damper 24 are closed. Thereby, the 2nd air flow path 15B which reaches the living room L through the 1st space 5A and the 2nd space 5B of the panel 2 from the air conditioner 31 (duct 36) is set. Therefore, at least a part of the second air flow path 15B of the present embodiment is formed by a gap between the humidity control boards 16a and 16a (shown in FIG. 4), and in the panel 2 facing the living room L. It has been extended. In the present embodiment, the fan 37 of the duct 36 is operated. By such a second air flow path 15B, the high-temperature air-conditioned air Aw is supplied to the humidity control means 16 (shown in FIG. 4) disposed inside the panel 2.

  High-temperature air-conditioned air Aw has a lower relative humidity than outdoor air Ao (shown in FIG. 16). For this reason, the water | moisture content contained in the humidity control means 16 can be discharge | released effectively in the high temperature air-conditioned air Aw which circulates through the 2nd air flow path 15B. Accordingly, the second air flow path 15B of this embodiment increases the relative humidity by dehumidifying the humidity adjusting means 16 (shown in FIG. 4) that has absorbed moisture by the first air flow path 15A (shown in FIG. 16). The third air A3 can be obtained.

  The 3rd air A3 which raised the relative humidity is discharged | emitted by the living room L through the 2nd outlet 14b. Thus, since the 2nd air flow path 15B of this embodiment can supply the high temperature and high humidity 3rd air A3 to the living room L, it can make the heating and humidification of the living room L compatible.

  The difference in relative humidity between the outdoor air and air-conditioned air shown in FIG. 14 is the difference in relative humidity between the outdoor air shown in FIG. 5 and the air in the living room, and the air and air-conditioning shown in FIG. Greater than the difference in relative humidity with the conditioned air. Therefore, the humidity control system of this embodiment has a moisture absorption amount to the humidity control means 16 (shown in FIG. 4) and the moisture content of the humidity control means 16 compared to the humidity control systems of the previous embodiments. Since the discharge amount can be increased, the humidity control function can be effectively exhibited.
