Description

  The present invention relates to, for example, a humidity control system that can be used for humidity adjustment of a living room space and the like, and an air supply method for a humidity control apparatus.

  For example, Patent Literature 1 below proposes a humidity control system that can be used for humidity control in a living room space of a house. The humidity control system includes a chamber in which a humidity control material is disposed, an air intake port for supplying air into the chamber, and an air intake port for taking out air that has passed through the chamber. The air intake port is provided on one end side of the chamber, and the air intake port is provided on the other end side of the chamber.

  The humidity control system has a function of adsorbing water vapor to the humidity control material (moisture absorption mode). In the moisture absorption mode, air with high relative humidity (for example, low-temperature air such as outside air in winter) is supplied to the chamber from the air intake port. The supplied air passes water vapor to the humidity control material when passing through the inside of the chamber, and is usually taken out from the air outlet with the relative humidity lowered.

  The humidity control system has a function of releasing water vapor adsorbed by the humidity control material into the air (humidity release mode). In this moisture release mode, air with low relative humidity (for example, air warmed by an air conditioner) is supplied to the chamber from the air intake port. When the supplied air passes through the inside of the chamber, it receives water vapor from the humidity control material, and is usually taken out from the air outlet in a state where the relative humidity is increased.

  As described above, in the humidity control system of Patent Document 1, air is supplied from the air intake port of the chamber and taken out from the air intake port in the moisture absorption mode and the moisture release mode. That is, air always flows in the same direction in the chamber.

  By the way, in the humidity control system, in the moisture absorption mode, the relative humidity of the air in the chamber is lower toward the downstream side of the flow. On the other hand, in the moisture release mode, the relative humidity of the air in the chamber is higher on the downstream side than on the upstream side, but not much higher than the relative humidity on the downstream side in the moisture absorption mode. For this reason, in the humidity control system, when the moisture absorption mode and the moisture release mode are switched, the relative humidity difference of the air in the chamber is large on the upstream side (that is, the air intake side), and the downstream side (air intake side). On the exit side), it becomes smaller and a large deviation occurs.

  Here, the moisture conditioning material has a larger moisture absorption / release amount as the relative humidity difference of the air touching the humidity conditioning material is larger. Therefore, the humidity control system has a problem in that the moisture absorption / release performance of the humidity control material cannot be widely used on the downstream side in the air flow direction.

  The present invention has been devised in view of the actual situation as described above, and is a humidity control system and a humidity control apparatus capable of widely utilizing the moisture absorption / release performance of the humidity control material in the direction of air flow in the chamber.

In order to adsorb water vapor to the humidity control material, the first air is supplied into the casing from the first end side and taken out from the second end side, and in the moisture absorption mode. Subsequently, in order to release the moisture of the humidity control material to the second air, The second air, into the interior of the casing, and executes the desorption mode is supplied from the second end side taken out from the first end portion side.

  In the humidity control system according to the present invention, the casing has a first inlet through which the first air is supplied and a first outlet through which the second air is taken out on the first end side. May be.

  In the humidity control system according to the present invention, the casing has a second inlet to which the second air is supplied and a second outlet from which the first air is taken out on the second end side. May be.

  In the humidity control system according to the present invention, the humidity control material includes elements that define a plurality of cylindrical spaces through which air passes in the longitudinal direction, and the first end side and the second end of the element. At least one end on the part side may be formed obliquely with respect to a plane orthogonal to the longitudinal direction.

A first step of supplying from the first end side and taking out from the second end side, and following the first step, in order to cause the second air to release water vapor from the humidity control material, the second step Air is supplied to the inside of the casing from the second end side and the first end side is supplied. Characterized in that it comprises a second step of taking.

The air supply device or the like supplies the first air into the casing from the first end side in order to adsorb the water vapor of the first air having a high relative humidity to the humidity control material. The moisture absorption mode is taken out from the side. Further, following the moisture absorption mode, the air supply device or the like supplies the second air into the casing in order to release the water vapor of the humidity control material to the second air having a low relative humidity. A moisture release mode is performed in which the air is supplied from the two end portions and taken out from the first end portion.

  In the humidity control system of the present invention, in the moisture absorption mode, the relative humidity of the air inside the casing is changed from the first end to the second end with the adsorption of the water vapor to the humidity control material. It can be lowered toward the side. On the other hand, in the moisture release mode, the relative humidity of the air inside the casing is changed from the second end side toward the first end side due to the release of the water vapor of the moisture conditioning material into the air. Can be high. That is, in the moisture release mode, the relative humidity of the air inside the casing can be lowered from the first end side toward the second end side, as in the moisture absorption mode.

  As described above, the humidity control system of the present invention can reduce the deviation of the relative humidity difference of air in the longitudinal direction of the casing between the moisture absorption mode and the moisture release mode. Therefore, the moisture absorption / release performance of the humidity control material can be fully utilized in the longitudinal direction in the casing.

The air conditioner 41 includes an indoor unit 41 a installed inside the building 2 and an outdoor unit (not shown) installed outside the building 2. The indoor unit 41 a is stored in the heat source chamber 43. Such an air conditioner 41 can blow out the 2nd air A2 (shown in FIG. 4) with the low relative humidity air-conditioned (heated) by the indoor unit 41a.

  The heat source chamber 43 defines a thermally insulated space. In the heat source chamber 43, an air-fuel mixture of the indoor air A3 and fresh outside air A4 is guided to an air inlet (not shown) of the indoor unit 41a. Then, the heat source chamber 43 converts the second air A2 having a low relative humidity, in which the air-fuel mixture is heated by the indoor unit 41a, into the humidity control device 5 (the first humidity control device 5A and the second humidity control device) via the first flow path 42. It is supplied to the wet device 5B).

  The first flow path 42 is configured as a duct formed in a cylindrical shape. The outer surface of the duct is preferably covered with a heat insulating material (not shown). Thereby, the fluctuation | variation of the temperature (hence a relative humidity (relative vapor pressure)) of 2nd air A2 can be suppressed to the minimum. The 1st flow path 42 is not necessarily limited to the aspect comprised by a duct, For example, you may form in the space enclosed by partitions, such as a partition wall (illustration omitted).

  One end of the first flow path 42 is connected to the heat source chamber 43. The other end of the first flow path 42 is connected to the second inlet 13 of the humidity control apparatus 5. The other end of the first flow path 42 of this embodiment is branched and connected to the second inlet 13 (not shown) of the first humidity control device 5A and the second inlet 13 of the second humidity control device 5B. Yes.

  For example, the second air supply device 24 starts the air conditioner 41 in a state where the second inlet 13 of the humidity control device 5 (the first humidity control device 5A or the second humidity control device 5B) is opened. Thus, the second air A2 (shown in FIG. 4) that has been air-conditioned by the air conditioner 41 is used as the humidity control material 10 of the humidity control device 5 (the first humidity control device 5A and the second humidity control device 5B). (Shown in FIG. 4).

  As shown in FIG. 1, the second air take-out device 25 is for taking out the second air A2 (shown in FIG. 4) from which the water vapor of the humidity control material 10 has been released from the humidity control device 5 (casing 9). Is. The 2nd air extraction device 25 of this embodiment is formed by the duct formed in the cylinder shape, for example. The outer surface of the duct is preferably covered with a heat insulating material. In addition, the 2nd air extraction apparatus 25 is not necessarily limited to the aspect formed with a duct, For example, you may form in the space enclosed by partitions, such as a partition wall (illustration omitted).

  One end of the second air extraction device 25 is connected to the first outlet 12 of the humidity control device 5. One end of the second air extraction device 25 of this embodiment is branched and connected to the first outlet 12 (not shown) of the first humidity control device 5A and the first outlet 12 of the second humidity control device 5B. The other end of the second air extraction device 25 is branched and connected to the living rooms 3 and 3.

  For example, the second air take-out device 25 can open the first outlet 12 of the humidity control device 5 (the first humidity control device 5A and the second humidity control device 5B) so that the water vapor of the humidity control material 10 is generated. The discharged second air A2 (shown in FIG. 4) can be supplied to the living room 3.

  The control device 26 (shown in FIG. 1) is configured as a microcomputer, for example, and includes a calculation unit (not shown) composed of a CPU (central processing unit) and a storage unit (not shown) in which control procedures are stored in advance. And a working memory (not shown) for reading a control procedure from the storage unit.

  The air supply apparatus 6 having the above configuration executes a moisture absorption mode and a moisture release mode. As shown in FIG. 3, the moisture absorption mode is executed to adsorb the water vapor of the first air A <b> 1 having a high relative humidity to the humidity control material 10. In the moisture absorption mode of the present embodiment, the first air A1 is supplied into the casing 9 from the first end 9a side and taken out from the second end 9b side. On the other hand, as shown in FIG. 4, the moisture release mode is executed to release the water vapor of the humidity control material 10 to the second air A <b> 2 having a low relative humidity. The moisture release mode of the present embodiment is executed following the moisture absorption mode, and the second air A2 is supplied into the casing 9 from the second end 9b side and taken out from the first end 9a side.

  The moisture absorption mode and moisture release mode of the present embodiment are based on a predetermined procedure (that is, an air supply method) for supplying air (first air A1 and second air A2) to the humidity control device 5. The control device 26 is executed by controlling the damper 21, the first air supply device 22, the first air extraction device 23, the second air supply device 24, and the second air extraction device 25. FIG. 7 is a flowchart illustrating an example of a processing procedure of the air supply method.

  In the air supply method of the present embodiment, after the air supply device 6 (control device 26) starts measuring time (step S1), the air supply device 6 executes the moisture absorption mode of the first humidity control device 5A ( 1st process S2) and the moisture release mode of the 2nd humidity control apparatus 5B are performed (2nd process S3). In the present embodiment, the first step S2 and the second step S3 are performed simultaneously. Fig.8 (a) is a figure which shows an example of the moisture absorption mode of 5 A of 1st humidity control apparatuses, and the moisture release mode of the 2nd humidity control apparatus 5B.

  In the moisture absorption mode (first step S2) of the first humidity control device 5A of the present embodiment, first, the second outlet 14 of the first humidity control device 5A is opened by the first electric damper 21C, and the second humidity control device. The second outlet 14 of 5B is closed with the first electric damper 21C. Next, in the moisture absorption mode of the first humidity control device 5A, the air blowing means 39 of the first air extraction device 23 is activated. In addition, when the ventilation means 39 has already started, it is not necessary to restart the ventilation means 39 again. As a result, in the moisture absorption mode of the first humidity control device 5A, the inside of the casing 9 of the first humidity control device 5A has a negative pressure, and the first humidity control device is caused by a pressure difference between the outside of the first humidity control device 5A. The first differential pressure damper 21A (first inlet 11) of 5A can be opened.

  By opening the first inlet 11 of the first humidity control device 5A, in the moisture absorption mode (first step S2) of the first humidity control device 5A, the casing 9 of the first humidity control device 5A and the cabin shown in FIG. The back 28 (or the outdoor 29) can be communicated. Thereby, in the moisture absorption mode of the first humidity control device 5A, the first air (the outside air or the air in the hut 28) A1 having a high relative humidity is passed through the first air supply device 22 to the first humidity control device 5A. It can be supplied to the humidity control material 10 (shown in FIG. 3). By supplying the first air A1, in the moisture absorption mode of the first humidity control device 5A, the water vapor of the first air A1 can be adsorbed to the humidity control material 10 of the first humidity control device 5A.

  The first air A1 in which water vapor is adsorbed on the humidity control material 10 (that is, the relative humidity has decreased) is taken out of the first humidity control device 5A by the first air extraction device 23. In this embodiment, the 1st air A1 which made water vapor | steam adsorb | suck to the humidity control material 10 is discharged | emitted to the cabin back 28 (or outdoor 29) shown in FIG. Thereby, the apparatus 6 such as an air supply does not reduce the humidity and temperature of the living room 3 (shown in FIG. 1).

  In the moisture release mode (second step S3) of the second humidity control device 5B of the present embodiment, first, the second inlet 13 of the second humidity control device 5B is opened by the second electric damper 21D, and the first humidity control is performed. The second inlet 13 of the device 5A is closed with the second electric damper 21D. Next, in the moisture release mode of the second humidity control device 5B, the air conditioner 41 (shown in FIG. 1) of the second air supply device 24 is activated. In addition, when the air conditioner 41 has already started, it is not necessary to restart the air conditioner 41 again. Thereby, in the moisture release mode of the second humidity control device 5B, the second air A2 having a low relative humidity that has been air-conditioned by the air conditioner 41 is supplied to the second humidity control device 5B via the first flow path 42. be able to. By supplying the second air A2, in the moisture release mode of the second humidity control device 5B, the water vapor adsorbed by the humidity control material 10 (shown in FIG. 4) of the second humidity control device 5B is released to the second air A2. Can be made.

  By supplying the second air A2, the inside of the casing 9 of the second humidity control device 5B becomes a positive pressure. Therefore, the second differential pressure damper 21B (first outlet) is caused by the pressure difference between the outside and the inside of the second humidity control device 5B. 12) can be opened. Thereby, in the moisture release mode of the second humidity control apparatus 5B, the second air A2 from which the water vapor of the humidity control material 10 (shown in FIG. 4) has been released (that is, the relative humidity has been increased) is discharged to the first outlet. 12 and the second air extraction device 25 can be supplied to the living room 3 (shown in FIG. 1).

  As described above, in the moisture release mode, it is possible to effectively humidify the room 3 while heating the room 3 in the winter when the relative humidity of the room 3 (shown in FIG. 1) is lower than that in the summer. Moreover, since the air supplied to the living room 3 is supplied to the air conditioner 41 via the heat source chamber 43 shown in FIG. 1, the indoor air A3 that has been heated and air-conditioned can be reused.

  Next, in the air supply method of the present embodiment, the air supply device 6 (control device 26) determines whether or not a predetermined time has elapsed (step S4). In Step S4, when the result is negative (“N” in Step S4), the first step S2 and the second step S3 are looped. Therefore, in the air supply method of the present embodiment, the moisture absorption mode of the first humidity control device 5A and the moisture release mode of the second humidity control device 5B are executed until a predetermined time elapses. The “time” can be arbitrarily set. The said time is set as the last time until the water vapor | steam of the humidity control material 10 of the 2nd humidity control apparatus 5B is completely discharge | released based on the moisture absorption / release performance etc. of the humidity control material 10 (shown in FIG. 4). It is desirable to be done.

  On the other hand, if the result is affirmative in step S4 (“Y” in step S4), the air supply device 6 (control device 26) resets the previous time measurement (step S5), and starts a new time measurement. Is started (step S6).

  Next, in the air supply method of the present embodiment, the air supply device 6 executes the moisture release mode of the first humidity control device 5A (second step S7), and the moisture absorption mode of the second humidity control device 5B. Is executed (first step S8). The second step S7 and the first step S8 are performed simultaneously. FIG. 8B is a diagram illustrating an example of a moisture release mode of the first humidity control device 5A and a moisture absorption mode of the second humidity control device 5B.

  In the moisture release mode (second step S7) of the first humidity control device 5A of the present embodiment, first, the second inlet 13 of the first humidity control device 5A is opened by the second electric damper 21D and the second humidity control is performed. The second inlet 13 of the device 5B is closed with the second electric damper 21D. Next, in the moisture release mode of the first humidity control device 5A, the air conditioner 41 (shown in FIG. 1) of the second air supply device 24 is activated. In addition, when the air conditioner 41 has already started, it is not necessary to restart the air conditioner 41 again. Thereby, in the moisture release mode of the first humidity control apparatus 5A, the second air A2 having a low relative humidity that is air-conditioned by the air conditioner 41 is supplied to the first humidity control apparatus 5A via the first flow path 42. be able to. By supplying the second air A2, in the moisture release mode of the first humidity control device 5A, the water vapor adsorbed on the humidity control material 10 (shown in FIG. 4) of the first humidity control device 5A in the first step S2 The second air A2 can be discharged.

  By supplying the second air A2, the inside of the casing 9 of the first humidity control device 5A becomes a positive pressure. Therefore, the second differential pressure damper 21B (first outlet) is caused by a pressure difference between the inside and the outside of the first humidity control device 5A. 12) can be opened. Thereby, in the moisture release mode of the first humidity control apparatus 5A, the second air A2 from which the water vapor of the humidity control material 10 has been released (that is, the relative humidity has been increased) is changed to the first outlet 12 and the second air. It can be supplied to the living room 3 (shown in FIG. 1) via the air take-out device 25.

  In the moisture absorption mode (first step S8) of the second humidity control apparatus 5B of the present embodiment, first, the second outlet 14 of the second humidity control apparatus 5B is opened by the first electric damper 21C, and the first humidity control apparatus is used. The second outlet 14 of 5A is closed with the first electric damper 21C. Next, in the moisture absorption mode of the second humidity control device 5B, the air blowing means 39 of the first air extraction device 23 is activated. In addition, when the ventilation means 39 has already started, it is not necessary to restart the ventilation means 39 again. Thereby, in the moisture absorption mode of the 2nd humidity control apparatus 5B, the inside of the casing 9 of the 2nd humidity control apparatus 5B becomes a negative pressure, and the 2nd humidity control apparatus by the external pressure difference in the 2nd humidity control apparatus 5B The first differential pressure damper 21A (first inlet 11) of 5B can be opened.

  By opening the first inlet 11 of the second humidity control device 5B, in the moisture absorption mode (first step S8) of the second humidity control device 5B, the casing 9 of the second humidity control device 5B and the hut shown in FIG. The back 28 (or the outdoor 29) can be communicated. Thereby, in the moisture absorption mode of the second humidity control device 5B, the first air (the outside air or the air in the hut 28) A1 having a high relative humidity is supplied to the first humidity control device 5A via the first air supply device 22. It can be supplied to the humidity control material 10. By supplying the first air A1, in the moisture absorption mode of the second humidity control device 5B, the first humidity control material 10 (shown in FIG. 3) of the second humidity control device 5B that has released water vapor in the second step S3 is supplied to the first humidity control device 5B. Water vapor in the air A1 can be adsorbed.

  The first air A1 in which water vapor is adsorbed on the humidity control material 10 (that is, the relative humidity has decreased) is taken out of the second humidity control device 5B by the blowing means 39 of the first air extraction device 23. In the present embodiment, the first air A1 in which water vapor is adsorbed on the humidity control material 10 is discharged to the back of the hut 28 (or outdoors 29).

  Next, in the air supply method of the present embodiment, the air supply device 6 (control device 26) determines whether or not the predetermined time has elapsed (step S9). If the result is negative in step S9 (“N” in step S9), the second step S7 and the first step S8 are looped. Therefore, the moisture absorption mode of the second humidity control device 5B and the moisture release mode of the first humidity control device 5A are executed until a predetermined time elapses. The time is set as the last time until the water vapor of the humidity control material 10 of the first humidity control device 5A is completely released based on the moisture absorption / release performance of the humidity control material 10, for example. desirable.

  In step S9, when the result is affirmative (“Y” in step S9), the air supply device 6 (control device 26) resets the previous time measurement (step S10) and starts a new time measurement. (Step S1). Thereafter, step S2 and subsequent steps are repeated. Note that such a procedure (that is, an air supply method) is interrupted or terminated by an operation by a user or the like.

  As described above, in the air supply method (humidity control system 1) of the present embodiment, in the first humidity control device 5A and the second humidity control device 5B, the moisture absorption mode and the moisture absorption mode are executed following the moisture absorption mode. Therefore, the adsorption of the water vapor of the first air A1 to the humidity control material 10 and the release of the water vapor adsorbed by the humidity control material 10 to the second air A2 can be continuously performed.

  Furthermore, in the air supply method (humidity control system 1) of the present embodiment, the first humidity control device 5A and the second humidity control device 5B always execute different modes (a moisture absorption mode and a moisture release mode). Thereby, as shown in FIG. 8A, the air supply method (humidity control system 1) performs the moisture release of the second humidity control device 5B while executing the moisture absorption mode of the first humidity control device 5A. The mode can be executed. On the other hand, as shown in FIG. 8B, in the air supply method (humidity control system 1), while the moisture release mode of the first humidity control device 5A is being executed, the moisture absorption mode of the second humidity control device 5B Can be executed. Therefore, in the air supply method (humidity control system 1) of the present embodiment, the humidity control mode and the moisture release mode are alternately switched in each of the first humidity control device 5A or the second humidity control device 5B. The air-conditioned second air A2 having a low relative humidity can be continuously supplied to the living room 3.

  Fig.9 (a) is a graph which shows an example of the relative humidity measured inside the casing 9 of the humidity control system 1 of this embodiment. FIG.9 (b) is a graph which shows an example of the relative humidity measured inside the casing of the conventional humidity control system. The relative humidity in FIGS. 9A and 9B indicates the relative humidity measured 30 minutes after the start of the moisture absorption mode and the moisture release mode.

  In the moisture absorption mode of the present embodiment (for example, the moisture absorption mode of the first humidity control device 5A shown in FIG. 8A and the moisture absorption mode of the second humidity control device 5B shown in FIG. 8B), the relative The first air A1 having high humidity is supplied into the casing 9 from the first end 9a side and taken out from the second end 9b side. Therefore, in the moisture absorption mode, as shown in FIG. 9A, the relative humidity of the air inside the casing 9 is increased from the first end 9a side to the second with the adsorption of water vapor to the humidity control material 10. It becomes lower toward the end portion 9b side.

  Moisture release mode of the present embodiment (for example, the moisture release mode of the second humidity control device 5B shown in FIG. 8A and the moisture release mode of the first humidity control device 5A shown in FIG. 8B) Then, the second air A2 having a low relative humidity is supplied into the casing 9 from the second end 9b side and taken out from the first end 9a side. For this reason, in the moisture release mode, the relative humidity of the air inside the casing 9 increases from the second end portion 9b side to the first end portion 9a side due to the release of the water vapor of the humidity control material 10 into the air. Become. That is, in the moisture release mode of the present embodiment, the relative humidity of the air inside the casing 9 can be lowered from the first end portion 9a side to the second end portion 9b side, similarly to the moisture absorption mode.

  On the other hand, in the related art (for example, Patent Document 1), the first air A1 and the second air A2 are supplied in the same direction (from the first end 9a side to the second end 9b side). For this reason, in the conventional moisture release mode, as shown in FIG. 9B, the relative humidity of the air inside the casing 9 is different from the moisture absorption mode, and from the first end 9a side to the second end 9b. Get higher toward the side.

  As is clear from FIGS. 9A and 9B, the humidity control system 1 of the present embodiment has a relative humidity difference D2 between the moisture absorption mode and the moisture release mode as compared with the conventional humidity conditioning system. The bias can be reduced in the longitudinal direction D1 (from the first end portion 9a side to the second end portion 9b side). Here, the humidity adjustment material 10 has a larger moisture absorption / release amount as the relative humidity difference D2 of the air in contact with the humidity adjustment material 10 is larger. Therefore, in the humidity control system 1 (air supply method) of this embodiment, the moisture absorption / release performance of the humidity control material 10 is fully utilized in the longitudinal direction in the casing 9 as compared with the conventional humidity control system. Can do. In order to effectively utilize such moisture absorption / release performance, the first air A1 and the second air A2 are set so that the relative humidity difference D2 between the moisture absorption mode and the moisture release mode is 10% RH or more. Is preferably supplied.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.

  Using the humidity control system shown in FIGS. 1 to 3, the room of the building (house) was conditioned (Example, Comparative Example). In the air supply apparatus (air supply method) of the embodiment, the first air having a high relative humidity is supplied from the first end side of the casing and is supplied from the second end side based on the procedure shown in FIG. Moisture absorption mode (first step) to be taken out, and moisture absorption mode (first step), following the moisture absorption mode (first step), the second air having a low relative humidity is supplied from the second end side of the casing and taken out from the first end side. The mode (second step) was executed.

On the other hand, in the comparative example, as in Patent Document 1, the moisture absorption is performed by supplying the first air having a high relative humidity and the second air having a low relative humidity from the first end side of the casing and taking out from the second end side. Mode and moisture release mode were implemented. And in the Example and the comparative example, the relative humidity measured 30 minutes after starting moisture absorption mode and moisture release mode was measured. The relative humidity of an Example and a comparative example is as follows.
First air (outside air):
Temperature: 5 ° C
Relative humidity: 60% RH
Air volume (air blowing means): 150 m ³ / h
Second air:
Temperature: 30 ° C
Relative humidity: 22% / RH
Air volume (air conditioner): 170m ³ / h
Conditioning material:
Element: Pulp fiber
Dimensions: Vertical: 0.25m
Next: 0.25m
Depth: 0.88m
Adsorbent: Silica gel (A-type silica gel specified in JIS Z0701)
The test results are shown in Table 1.

  As a result of the test, as shown in Table 1, in the example, the relative humidity difference D2 on the second end side is slightly smaller than the comparative example, but the relative humidity difference D2 on the second end side is slightly smaller. Was able to be enlarged. Therefore, in the humidity control system (air supply method) of the embodiment, as compared with the conventional humidity control system (air supply method), the relative humidity difference D2 between the moisture absorption mode and the moisture release mode is reduced. It was small in the longitudinal direction (from the first end side to the second end side). As a result, the humidity control system (air supply method) of the embodiment fully utilizes the moisture absorption / release performance of the humidity control material in the longitudinal direction in the casing as compared to the conventional humidity control system (air supply method). We were able to.
