[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be understood that the drawings include exaggerated representations and representations that differ from the dimensional ratios of actual structures in order to facilitate understanding of the contents of the invention. Furthermore, identical or common elements are designated by the same reference numerals throughout the embodiments, and redundant explanations will be omitted. Furthermore, the specific configurations shown in the embodiments and drawings are for the purpose of understanding the contents of the present invention, and the present invention is not limited to the specific configurations shown in the drawings.

[0015] The humidity control device of this embodiment is for controlling the humidity of air. The humidity control device of this embodiment is configured as a batch-type humidity control device that can alternately repeat moisture release and moisture absorption in a predetermined cycle.

[0016] The humidity control apparatus of this embodiment is installed in a house equipped with a central air conditioning system. In this embodiment, the humidity control apparatus is disposed in an air transport path to living rooms.

[0017] [Residential] 1 is a cross-sectional view conceptually showing a house 2 equipped with a central air-conditioning system 1. The house 2 of this embodiment is configured to include, for example, an underfloor space 3 and an above-floor space 4.

[0018] In this embodiment, the above-floor space 4 is provided with, for example, a plurality of rooms 5. The rooms 5 include rooms on the first floor, but may also include rooms on the second floor or higher (not shown). Each room 5 is separated by, for example, a door 6, and air A2 circulates through gaps 7 formed in the door 6.

[0019] [Whole building air conditioning system] The central air-conditioning system 1 of this embodiment is for adjusting the humidity of air A1 conditioned by an air conditioner 13 (hereinafter, sometimes simply referred to as "conditioned air") and supplying the air to a plurality of rooms 5.

[0020] The whole-building air-conditioning system 1 of this embodiment is configured to include an air conditioning / humidity control unit 10 and a first flow path 11. The first flow path 11 of this embodiment is connected between the air conditioning / humidity control unit 10 and a plurality of living rooms 5. This enables the first flow path 11 to supply conditioned air (humidity-controlled conditioned air) A1 from the air conditioning / humidity control unit 10 to a plurality of living rooms 5. The first flow path 11 of this embodiment can be configured as appropriate as long as it can supply conditioned air A1 to a plurality of living rooms 5. The first flow path 11 of this embodiment is formed by a duct formed in a cylindrical shape, but may also be formed, for example, by a space surrounded by a partition wall (not shown).

[0021] [Air conditioning and humidity control unit] The air conditioning / humidity control unit 10 of this embodiment is configured to include a main casing 12, an air conditioner 13, an air compressor 14, and a humidity control device 15 (humidity control section 16). Furthermore, a filter member 17 is arranged in the air conditioning / humidity control unit 10 of this embodiment. Fig. 2 is a perspective view showing the main casing 12 of the air conditioning / humidity control unit 10. Fig. 3 is a partial perspective view of Fig. 2. Fig. 4 is a partial cross-sectional view of Fig. 2. In this embodiment, the position of each component of the air conditioning / humidity control unit 10 is specified on an orthogonal coordinate system consisting of an x-axis, a y-axis, and a z-axis that is perpendicular to the x-axis and y-axis.

[0022] [Main casing] 2 and 3, the main casing 12 of this embodiment is formed in a box shape having an internal space 18. The space 18 of this embodiment is divided by a frame 19 and a face material 20 supported by the frame 19. The face material 20 may include, for example, a heat insulating material (not shown) for insulating the interior of the space 18 from the outside of the main casing 12.

[0023] 3 and 4, the space 18 in this embodiment is divided into a first space 18A, a second space 18B, and a third space 18C by a first partitioning surface member 20A (including, in this example, a first side surface member 33A of the sub-casing 27) provided in the main casing 12. The first partitioning surface member 20A (first side surface member 33A) in this embodiment is disposed in the center of the main casing 12 in the x-axis direction. As a result, the first space 18A and the second space 18B are adjacent to each other in the x-axis direction, with the first partitioning surface member 20A (first side surface member 33A) interposed therebetween.

[0024] In this embodiment, the first partition surface member 20A (first side surface member 33A) extends in the z-axis direction from one end (in this example, the upper end) of the main casing 12 to the other end (in this example, the lower end) and terminates without reaching the other end. As a result, the space 18 is divided into a third space 18C that communicates with the first space 18A and the second space 18B on the other end side of the first partition surface member 20A (first side surface member 33A).

[0025] 2 and 3, the main casing 12 of this embodiment is provided with an openable and closable door section 21. Opening this door section 21 allows easy access to the internal space 18 of the main casing 12. This improves the ease of maintenance of the air conditioning and humidity control unit 10. The door section 21 of this embodiment is configured to include a first door section 21A and a second door section 21B. The first door section 21A and the second door section 21B are aligned in the direction of the z-axis (in this example, the up-down direction) z, but this is not particularly limited.

[0026] As shown in Figures 2 to 4, the main casing 12 of this embodiment has at least one inlet 22, at least one outlet 23, and an internal flow passage 24 (shown in Figure 4) that connects the inlet 22 and the outlet 23.

[0027] The inlet 22 of this embodiment is for supplying air to the space 18 of the main casing 12. The inlet 22 of this embodiment is formed, for example, as a hole that connects the outside of the main casing 12 (in this example, the above-floor space 4 shown in FIG. 1 ) with the space 18 of the main casing 12.

[0028] In this embodiment, the inlet 22 is provided on one end (upper end) of the main casing 12 in the direction of the z-axis. Furthermore, the inlet 22 is provided on one side (first space 18A) of the first partition surface material 20A in the direction of the x-axis. This allows the inlet 22 to supply air (in this example, air A2 inside the house 2) to the first space 18A.

[0029] In this embodiment, the inlet 22 is formed so as to be able to supply air A2 inside the house 2 (in this example, return air from the multiple living rooms 5) to the space 18 of the main casing 12, but is not limited to this. The inlet 22 may be formed so as to be able to supply, for example, outside air for ventilation (not shown). Furthermore, a plurality of inlets 22 may be provided so as to be able to supply the air A2 inside the house 2 and the outside air for ventilation independently.

[0030] The outlet 23 in this embodiment is for supplying, for example, conditioned air (in this example, humidity-controlled conditioned air) A1 in the space 18 of the main casing 12 to the outside of the main casing 12. The outlet 23 in this embodiment is formed as a hole that connects the space in the main casing 12 with the outside of the main casing 12 (in this example, the first flow path 11).

[0031] In this embodiment, the outlet 23 is provided on one end (upper end) of the main casing 12 in the direction of the z-axis. Furthermore, the outlet 23 is provided on the other side (second space 18B) of the first partition surface member 20A in the direction of the x-axis. This allows the outlet 23 to extract air from the second space 18B and supply it to the outside of the main casing 12 (in this example, the first flow path 11).

[0032] In this embodiment, the outlet 23 is connected to the first flow path 11. As a result, the air in the second space 18B (conditioned air A1) can be supplied from the outlet 23 through the first flow path 11 to a plurality of rooms 5 (shown in FIG. 1).

[0033] 4, the internal flow path 24 of this embodiment communicates between the inlet 22 and the outlet 23. As a result, the internal flow path 24 of this embodiment can condition the air (in this example, return air) A2 supplied from the inlet 22 by the air conditioner 13, and can also guide the conditioned air A1 to the outlet 23 (first flow path 11).

[0034] In this embodiment, the internal flow path 24 is made up of a first space 18A communicating with the inlet 22, a second space 18B communicating with the outlet 23, and a third space 18C communicating between the first space 18A and the second space 18B. As a result, the internal flow path 24 is formed in a U-shape when viewed from the side in the y-axis direction.

[0035] [Air conditioner] The air conditioner 13 of this embodiment is configured, for example, as a typical split-type air conditioner for home use. The air conditioner 13 includes, as a set, an indoor unit 13A and an outdoor unit (not shown) installed outside the house 2. The indoor unit 13A has an inlet 13a and an outlet 13b.

[0036] The air conditioner 13 (indoor unit 13A) of this embodiment is disposed in the internal flow path 24 of the main casing 12. In this embodiment, the indoor unit 13A is disposed in the first space 18A (on the inlet 22 side) of the internal flow path 24.

[0037] The air inlet 13a of this embodiment takes in air A2 supplied from the inlet 22 (in this example, air (return air) inside the house 2) and supplies it to a heat exchanger (not shown) provided inside the indoor unit 13A. On the other hand, the air outlet 13b of this embodiment discharges air A1 conditioned by the heat exchanger to the outlet 23 side (the downstream side of the internal flow path 24 (the third space 18C and second space 18B side)).

[0038] The set temperature and air volume (blowout air volume) of the air conditioner 13 are controlled, for example, by a control device 25 (shown in FIG. 1). The control device 25 of this embodiment is installed, for example, on a partition wall of the living room 5, but is not limited to this configuration. The control device 25 is configured to include a calculation unit (not shown) made up of a CPU (central processing unit), a memory unit (not shown) in which control procedures are stored in advance, and a working memory (not shown) for reading the control procedures from the memory unit.

[0039] [Air pressure supply device] 1 and 4, the air pressure feeder 14 of this embodiment is disposed in the internal flow path 24 of the main casing 12 and is intended to generate an air flow from the inlet 22 toward the outlet 23. This air flow allows air (return air) A2 within the house 2 to be taken in from the inlet 22 and conditioned by the air conditioner 13. Furthermore, the air flow allows conditioned air A1 discharged from the air conditioner 13 to be smoothly guided toward the outlet 23.

[0040] There are no particular limitations on the air pressure feeder 14 as long as it can generate the air flow described above. The air pressure feeder 14 of this embodiment is configured as a fan 14A.

[0041] In this embodiment, the air pressure sending tool 14 is located between the air conditioner 13 and the humidity control section 16 (in this example, the third space 18C) in the internal flow path 24, but is not limited to this. The air pressure sending tool 14 may be located, for example, between the humidity control section 16 (humidity control device 15) and the outlet 23.

[0042] [Filter material] The filter member 17 of this embodiment is for purifying air. The filter member 17 of this embodiment is disposed in the internal flow path 24 of the main casing 12. Such a filter member 17 can purify the air in the internal flow path 24.

[0043] The filter member 17 of this embodiment is located between the air conditioner 13 and the humidity control section 16 (humidity control device 15) in the internal flow path 24. This allows the filter member 17 to supply purified conditioned air A1 to the humidity control section 16, thereby preventing the humidity control section 16 from being soiled or damaged.

[0044] There are no particular limitations on the filter member 17 as long as it can purify the air. Examples of the filter member 17 include a HEPA (High Efficiency Particulate Air) filter, a photocatalytic filter, an activated carbon deodorizing filter, an electrostatic dust collecting filter, etc., which may be arranged alone or in combination.

[0045] [Humidity control device (humidity control section)] 4, the humidity control device 15 (humidity control section 16) of this embodiment is disposed in the internal flow path 24 of the main casing 12, and on the outlet 23 side of the air conditioner 13. This enables the humidity control device 15 (humidity control section 16) to control the humidity of the conditioned air A1 of the air conditioner 13.

[0046] The position of the humidity control device 15 (humidity control section 16) of this embodiment is not particularly limited as long as it is disposed in the internal flow path 24 of the main casing 12 and closer to the outlet 23 (downstream of the internal flow path 24) than the air conditioner 13. The humidity control device 15 (humidity control section 16) of this embodiment is provided in the second space 18B.

[0047] As shown in Figures 2 to 4, the humidity control device 15 of this embodiment is configured to include a casing 26 (sub-casing 27), a humidity control section 16 (shown in Figures 3 and 4), and a drive section 28 (shown in Figures 3 and 4).

[0048] [Casing (secondary casing)] The casing 26 of this embodiment is configured as a sub-casing 27 in which the humidity control section 16 (shown in FIGS. 3 and 4) is disposed within the main casing 12. As shown in FIG. 4, the casing 26 (sub-casing 27) of this embodiment is formed in a box shape having a space 29 therein.

[0049] The sub-casing 27 (casing 26) of this embodiment is fixed to the main casing 12 in a manner that allows it to be disassembled. This improves the maintainability of the humidity control device 15. The sub-casing 27 may also be configured integrally with the main casing 12 (fixed so that it cannot be disassembled). FIG. 5 is an exploded perspective view of the humidity control device 15. FIG. 6 is a cross-sectional view of the humidity control device 15.

[0050] 4 to 6, the casing 26 (sub-casing 27) of this embodiment is configured to include a bottom surface member 31 and a top surface member 32 arranged on both sides in the direction of the z-axis, and a plurality of side surface members 33 arranged between the bottom surface member 31 and the top surface member 32. A space 29 is defined in the casing 26 by the bottom surface member 31, the top surface member 32, and the plurality of side surface members 33.

[0051] In this embodiment, the lower surface member 31, the upper surface member 32, and the plurality of side surface members 33 are each formed to have a rectangular shape in a plan view. As a result, the casing 26 (sub-casing 27) is formed to have a rectangular shape in a plan view seen from each of the x-axis, y-axis, and z-axis directions. The lower surface member 31, the upper surface member 32, and the plurality of side surface members 33 may include a heat insulating material (not shown).

[0052] 5, the lower surface material 31 and the upper surface material 32 of this embodiment extend in the x-axis-y-axis plane. The lower surface material 31 and the upper surface material 32 are disposed spaced apart from each other in the z-axis direction.

[0053] As shown in FIGS. 4 to 6, the multiple side members 33 of this embodiment are configured to include a first side member 33A, a second side member 33B, a third side member 33C, and a fourth side member 33D.

[0054] In this embodiment, the first side member 33A and the second side member 33B extend in the y-axis-z-axis plane. These first side member 33A and second side member 33B are arranged spaced apart from each other in the x-axis direction. As shown in Fig. 4, the first side member 33A in this embodiment is fixed to the first partition panel member 20A of the main casing 12, but this is not limited to this.

[0055] 5, the third side member 33C and the fourth side member 33D of this embodiment extend in the x-axis-z-axis plane and are spaced apart from each other in the y-axis direction.

[0056] 5 and 6, the casing 26 (sub-casing 27) of this embodiment is provided with a second partition member 34 for dividing the space 29. The second partition member 34 of this embodiment extends in the x-axis-z-axis plane and is disposed between the third side member 33C and the fourth side member 33D in the y-axis direction. This second partition member 34 can divide the interior of the casing 26 into two spaces 29, 29 in the y-axis direction.

[0057] In the casing 26 (sub-casing 27) of this embodiment, one space 29 in the y-axis direction is configured as the second space 18B, and the other space 29 is configured as the fourth space 18D. The fourth space 18D of this embodiment does not communicate with the first space 18A and the third space 18C in the main casing 12 shown in FIG.

[0058] The casing 26 (sub-casing 27) of this embodiment is configured to include a first inlet 35A, a second inlet 35B, a first outlet 36A, and a second outlet 36B as air inlets and outlets.

[0059] The first inlet 35A of this embodiment is formed in the bottom surface member 31. On the other hand, the second inlet 35B of this embodiment is formed in the fourth side surface member 33D. Furthermore, the first outlet 36A and the second outlet 36B of this embodiment are formed in the top surface member 32. However, the positions of the first inlet 35A, the second inlet 35B, the first outlet 36A and the second outlet 36B are not limited to this embodiment.

[0060] The first inlet 35A and the first outlet 36A in this embodiment are provided on one side in the y-axis direction of the casing 26 (sub-casing 27) (in this example, one side (second space 18B side) of the second partition surface member 34). This allows the first inlet 35A and the first outlet 36A to communicate between the second space 18B and the outside of the casing 26 (sub-casing 27).

[0061] 4, the first inlet 35A of this embodiment communicates with the third space 18C (air pressure feeder 14) of the main casing 12. This allows the first inlet 35A to supply conditioned air A1 from the third space 18C to the second space 18B (one space 29). Meanwhile, the first outlet 36A of this embodiment constitutes the outlet 23 of the main casing 12. Therefore, the first flow path 11 is connected to the first outlet 36A.

[0062] The second inlet 35B and the second outlet 36B in this embodiment are provided on the other side in the y-axis direction of the casing 26 (sub-casing 27) (in this example, the other side (the fourth space 18D side) of the second partition surface member 34). As a result, the second inlet 35B and the second outlet 36B communicate between the fourth space 18D and the outside of the casing 26 (sub-casing 27).

[0063] The second inlet 35B of this embodiment is connected to an outside air supply unit 37 that supplies outside air A3 to the humidity control unit 16. As shown in FIG. 1, the outside air supply unit 37 of this embodiment is configured to include a second flow path 38. One end of the second flow path 38 is arranged in an attic 39 of the house 2. Outside air A3 for ventilation is supplied to this attic 39. Meanwhile, the other end of the second flow path 38 is connected to the second inlet 35B. As a result, outside air A3 is supplied to the fourth space 18D shown in FIGS. 5 and 6 via the second inlet 35B.

[0064] In this embodiment, the second flow path 38 is formed by a duct formed in a cylindrical shape, but is not particularly limited to this. The second flow path 38 may be formed, for example, by a space surrounded by a partition wall (not shown). As shown in Fig. 1, the second flow path 38 may be provided with a fan 40 capable of compressing and sending outside air A3 from one end side (the attic 39 side) to the other end side (the second inlet 35B side).

[0065] 5 and 6, the second outlet 36B in this embodiment is connected to one end of the third flow path 41. The other end of the third flow path 41 is disposed in the attic 39, as shown in Fig. 1. As a result, as shown in Figs. 5 and 6, air in the fourth space 18D can be supplied to the attic 39 (shown in Fig. 1) via the second outlet 36B and the third flow path 41.

[0066] 3 to 5, the casing 26 (sub-casing 27) of this embodiment is preferably provided with an openable / closable opening 42. By opening such an opening 42, the inside of the casing 26 (sub-casing 27) (in this example, the humidity control unit 16 (humidity control material 43)) can be easily accessed, improving maintainability.

[0067] The opening 42 can be set as appropriate as long as it allows the casing 26 (sub-casing 27) to be opened and closed. As shown in Figures 3 and 4, the opening 42 in this embodiment is provided on the other end (lower side) of the first side member 33A and is configured as a door that can rotate around the y-axis. When such opening 42 is opened, it becomes possible to easily access the interior of the sub-casing 27 from the outside of the main casing 12 via the door portion 21 (shown in Figure 2) and the space 18.

[0068] [Humidity control section] 5 and 6, the humidity control unit 16 of this embodiment includes a first chamber 45 and a second chamber 46 each having a humidity control material 43 therein for controlling the humidity of air passing through. The first chamber 45 and the second chamber 46 are arranged side by side in the y-axis direction.

[0069] [1st chamber and 2nd chamber] The first chamber 45 and the second chamber 46 can be formed as appropriate as long as they can accommodate the humidity conditioner 43 inside.

[0070] In this embodiment, the first chamber 45 is configured to include a first partition 47, a second partition 48, a first side member 33A, and a second side member 33B. A humidity control material 43 is placed in the internal space (first chamber 45) defined by the first partition 47, the second partition 48, the first side member 33A, and the second side member 33B.

[0071] In this embodiment, the first partition 47 is formed in a plate shape extending in the x-axis-z-axis plane. When the longitudinal direction of the first partition 47 is parallel to the z-axis, the first partition 47 forms part of the second partition surface member 34.

[0072] The second partitioning portion 48 of this embodiment is formed in a plate shape extending in the x-axis-z-axis plane, similar to the first partitioning portion 47. The second partitioning portion 48 is fixed to the first partitioning portion 47, for example, via a connecting portion (not shown).

[0073] In this embodiment, second chamber 46 is configured to include first partition 47, third partition 49, first side member 33A, and second side member 33B. Humidity conditioner 43 is placed in the internal space (second chamber 46) defined by first partition 47, third partition 49, first side member 33A, and second side member 33B.

[0074] The third partition portion 49 of this embodiment is formed in a plate shape extending in the x-axis-z-axis plane, similar to the first partition portion 47 and the second partition portion 48. The third partition portion 49 is fixed to the first partition portion 47, for example, via a connecting portion (not shown).

[0075] In this embodiment, the first chamber 45 and the second chamber 46 are provided with a rotation shaft 51 (which is the center of rotation of the humidity control unit 16) for rotating the humidity control unit 16 around the x-axis (the x-axis is an axis perpendicular to the y-axis and z-axis). The rotation shaft 51 in this embodiment is provided in the first partition section 47. One end of the rotation shaft 51 is supported by the drive unit 28 (shown in FIGS. 4 and 5). As shown in FIG. 4, the other end of the rotation shaft 51 is supported by a bearing (not shown) provided in the second side member 33B. This makes it possible to rotate the humidity control unit 16 around the x-axis.

[0076] 5 and 6, the first chamber 45 and the second chamber 46 of this embodiment are open at both ends in the longitudinal direction (the direction of the z-axis) of the first partition section 47, the second partition section 48, and the third partition section 49. This allows air to pass through the first chamber 45 and the second chamber 46 along the direction of the z-axis.

[0077] In order to allow the air supplied from the first inlet 35A and the second inlet 35B to pass efficiently into the first chamber 45 and the second chamber 46 (humidity control material 43), it is preferable that the casing 26 be provided with, for example, a fourth partition 52. In this embodiment, the fourth partition 52 is intended to fill the gap between the second partition 48 and the third side member 33C and the gap between the third partition 49 and the fourth side member 33D. Such a fourth partition 52 makes it possible to prevent the air supplied from the first inlet 35A and the second inlet 35B from passing through the gaps.

[0078] [Humidity-regulating material] The humidity-conditioning material 43 is for conditioning the humidity of the air passing through the first chamber 45 and the second chamber 46. The humidity-conditioning material 43 of this embodiment has moisture absorption and desorption properties that enable it to adsorb water vapor from air with a high relative humidity and to release the adsorbed water vapor into air with a low relative humidity.

[0079] There are no particular limitations on the humidity control material 43 as long as it has moisture absorption and release properties. The humidity control material 43 of this embodiment is composed of at least one humidity control element 53.

[0080] As shown in Fig. 5, the humidity control element 53 of this embodiment is formed by stacking a plurality of humidity control sheets 54 at intervals (for example, stacked in a honeycomb or double-tiered configuration) so that air (air along the z-axis direction) can pass through. Such a humidity control element 53 can effectively increase the moisture exchange area. The humidity control sheets 54 carry, for example, an adsorbent material (not shown) similar to that described in Patent Document 1.

[0081] In this embodiment, the volume of the humidity conditioner 43 per unit length in the y-axis direction of the first chamber 45 and the second chamber 46 is set to be larger the closer to the rotation axis 51. The volume of the humidity conditioner 43 per unit length in the y-axis direction of the first chamber 45 and the second chamber 46 can be formed as appropriate as long as it can be set to be larger the closer to the rotation axis 51. Each of the humidity conditioners 43, 43 in this embodiment is configured to include a plurality of humidity control elements 53. The plurality of humidity control elements 53 in this embodiment are fixed in a disassemblable manner.

[0082] The multiple humidity control elements 53 include multiple types with different lengths along the z-axis. The multiple humidity control elements 53 of this embodiment are configured to include a first humidity control element 53A and a second humidity control element 53B, but may also include other humidity control elements (not shown). The length along the z-axis of the first humidity control element 53A is greater than the length along the z-axis of the second humidity control element 53B.

[0083] In this embodiment, the first humidity control element 53A is disposed on the rotation axis 51 side in the first chamber 45 and the second chamber 46. Meanwhile, the second humidity control element 53B is disposed on the outer side of the first humidity control element 53A in the y-axis direction. As a result, the length L1 of the humidity control material 43 along the z-axis per unit length of the humidity control material 43 in the y-axis direction increases as the humidity control material 43 approaches the rotation axis 51. As a result, the volume of the humidity control material 43 per unit length of the humidity control material 43 in the y-axis direction also increases as the humidity control material 43 approaches the rotation axis 51.

[0084] [Drive unit] As shown in FIGS. 4 and 5, the drive unit 28 of this embodiment is for rotating the humidity control unit 16 (first chamber 45 and second chamber 46) around the x-axis within the casing 26 (sub-casing 27). The drive unit 28 is not particularly limited as long as it can rotate the humidity control unit 16. The drive unit 28 of this embodiment is configured as, for example, a motor that can be driven to rotate. Such a drive unit 28 can rotate the humidity control unit 16 by being connected to a rotation shaft 51.

[0085] In this embodiment, the drive unit 28 is fixed to the first side member 33A. As shown in Figures 3 and 4, in this embodiment, the drive unit 28 is exposed in the first space 18A. This allows easy access to the drive unit 28 from the door portion 21 provided in the main casing 12 through the first space 18A, improving maintainability.

[0086] The drive unit 28 of this embodiment is configured to be able to switch the humidity control unit 16 between a first state and a second state by rotating the humidity control unit 16 around the rotation axis 51 (180 degrees in this example). FIG. 7(a) is a cross-sectional view showing the first state. FIG. 7(b) is a cross-sectional view showing the second state. In FIG. 7, the humidity control material 43 in the first chamber 45 and the humidity control material 43 in the second chamber 46 are colored differently to make them easier to distinguish from each other. Furthermore, the outside air A3 in FIG. 7 is colored.

[0087] The switching between the first state (shown in FIG. 7(a)) and the second state (shown in FIG. 7(b)) may be performed by a resident of the house 2 operating the drive unit 28 (shown in FIGS. 4 and 5), or may be performed by the control device 25 (shown in FIG. 1) controlling the drive unit 28. In this embodiment, the control device 25 controls the drive unit 28, thereby switching the humidity adjustment unit 16 between the first state and the second state.

[0088] [First state] As shown in FIG. 7(a), the first state is a state in which air from the first inlet 35A flows through the first chamber 45 to the first outlet 36A, and air from the second inlet 35B flows through the second chamber 46 to the second outlet 36B.

[0089] Conditioned air A1 from the air conditioner 13 (shown in FIG. 4) is supplied to the first inlet 35A of the casing 26 (sub-casing 27). For example, in winter, when the air conditioner 13 is in heating operation, the relative humidity of the conditioned air (heated conditioned air) A1 decreases. When this conditioned air A1 with a low relative humidity passes from one end 45a to the other end 45b in the z-axis direction of the first chamber 45 (humidity control element 53), water vapor adsorbed to the humidity control material 43 (humidity control element 53) of the first chamber 45 is released. This increases the relative humidity of the conditioned air A1.

[0090] In the first state of this embodiment, the relative humidity of the air (conditioned air A1) in the first chamber 45 gradually increases from one end 45a of the first chamber 45 to the other end 45b due to the release of water vapor from the humidity control material 43 (humidity control element 53). Then, the conditioned air A1 with increased relative humidity (which has passed through the other end 45b of the first chamber 45) is supplied to the multiple rooms 5 (shown in FIG. 1) from the first outlet 36A of the casing 26 (sub-casing 27) via the first flow path 11. As a result, in the first state, the multiple rooms 5 can be effectively humidified while being heated.

[0091] Meanwhile, outside air A3 is supplied to the second inlet 35B of the casing 26 (sub-casing 27) from the outside air supply unit 37. For example, the outside air A3 in winter has a higher relative humidity than the outside air in summer (not shown). When the outside air A3 with a high relative humidity passes from one end 46a to the other end 46b in the z-axis direction of the second chamber 46, the water vapor contained in the outside air A3 is adsorbed by the humidity control material 43 (humidity control element 53) of the second chamber 46. This makes it possible to restore the humidifying capacity of the humidity control material 43.

[0092] In the first state of this embodiment, the relative humidity of the air (outside air A3) in the second chamber 46 gradually decreases from one end 46a to the other end 46b of the second chamber 46 due to adsorption of water vapor to the humidity control material 43 (humidity control element 53). Then, the outside air A3 with a reduced relative humidity (which has passed through the other end 46b of the second chamber 46) is supplied to the attic 39 (shown in FIG. 1) from the second outlet 36B via the third flow path 41. As a result, in the first state, it is possible to dehumidify the attic 39 (suppress condensation in the attic 39).

[0093] [Second state] As shown in FIG. 7(b), the second state is a state in which air from the first inlet 35A flows through the second chamber 46 to the first outlet 36A, and air from the second inlet 35B flows through the first chamber 45 to the second outlet.

[0094] Conditioned air A1 (in this example, conditioned air with a low relative humidity) from the air conditioner 13 is supplied to the first inlet 35A of the casing 26 (sub-casing 27). When this conditioned air A1 with a low relative humidity passes from the other end 46b to one end 46a of the second chamber 46, water vapor adsorbed by the humidity control material 43 in the second chamber 46 is released, and the relative humidity of the conditioned air A1 is increased.

[0095] In the second state of this embodiment, the relative humidity of the air (conditioned air A1) in the second chamber 46 gradually increases from the other end 46b to the one end 46a of the second chamber 46 due to the release of water vapor from the humidity control material 43 (humidity control element 53). The conditioned air A1 with increased relative humidity (having passed through the one end 46a of the second chamber 46) is supplied to the multiple rooms 5 (shown in FIG. 1) from the first outlet 36A of the casing 26 (sub-casing 27) via the first flow path 11. As a result, in the second state, the multiple rooms 5 can be effectively humidified while being heated, similar to the first state.

[0096] The flow of conditioned air A1 in the second chamber 46 in the second state (flow from the other end 46b to one end 46a) is opposite to (i.e., counterflow with) the flow of outside air A3 in the second chamber 46 in the first state shown in Figure 7(a) (flow from one end 46a to the other end 46b).

[0097] As described above, the relative humidity of the air (conditioned air A1) in the second chamber 46 in the second state gradually increases from the other end 46b to the one end 46a. Meanwhile, the relative humidity of the air (outside air A3) in the second chamber 46 in the first state gradually decreases from the one end 46a to the other end 46b (i.e., similar to the second state, the relative humidity gradually increases from the other end 46b to the one end 46a). This prevents the difference in relative humidity between the first state (shown in FIG. 7(a)) and the second state (shown in FIG. 7(b)) from becoming uneven from the one end 46a to the other end 46b of the second chamber 46 (i.e., the difference in relative humidity can be made closer to uniform). Therefore, the humidity control device 15 of this embodiment can utilize the moisture absorption and desorption performance of the humidity control material 43 throughout the entire second chamber 46 from the one end 46a to the other end 46b, similar to the patent document (JP 2019-207062 A).

[0098] In the second state, outside air A3 (outside air with a high relative humidity in this example) is supplied to the second inlet 35B of the casing 26 (sub-casing 27) from the outside air supply unit 37. When such outside air A3 with a high relative humidity passes from the other end 45b to the one end 45a of the first chamber 45, water vapor contained in the outside air A3 can be adsorbed by the humidity control material 43 in the first chamber 45, and the humidifying capacity of the humidity control material 43 can be restored.

[0099] In the second state of this embodiment, the relative humidity of the air (outside air A3) in the first chamber 45 gradually decreases from the other end 45b to the one end 45a of the first chamber 45 due to adsorption of water vapor to the humidity control material 43 (humidity control element 53). Then, the outside air A3 with a reduced relative humidity (which has passed through the one end 45a of the first chamber 45) is supplied to the attic 39 (shown in FIG. 1) from the second outlet 36B via the third flow path 41. As a result, in the second state, it is possible to dehumidify the attic 39 (suppress condensation in the attic 39).

[0100] The flow of outside air A3 in the first chamber 45 in the second state (flow from the other end 45b to one end 45a) is opposite to (i.e., counterflow with) the flow of conditioned air A1 in the first chamber 45 in the first state shown in Figure 7(a) (flow from one end 45a to the other end 45b).

[0101] As described above, the relative humidity of the air (outside air A3) in the first chamber 45 in the second state gradually decreases from the other end 45b to the one end 45a. Meanwhile, the relative humidity of the air (conditioned air A1) in the first chamber 45 in the first state gradually increases from the one end 45a to the other end 45b (i.e., similar to the second state, the relative humidity gradually decreases from the other end 45b to the one end 45a). This prevents the difference in relative humidity between the first state (shown in FIG. 7(a)) and the second state (shown in FIG. 7(b)) from becoming uneven from the one end 45a to the other end 45b of the first chamber 45 (i.e., the difference in relative humidity can be made closer to uniform). Therefore, the humidity control device 15 of this embodiment can fully utilize the moisture absorption and desorption performance of the humidity control material 43 throughout the entire first chamber 45 from the one end 45a to the other end 45b.

[0102] [Effects of humidity control devices (houses)] In this way, in the humidity control device 15 of the present embodiment, the drive unit 28 rotates the humidity control unit 16 around the x-axis, thereby switching the humidity control unit 16 between a first state (shown in FIG. 7(a)) and a second state (shown in FIG. 7(b)). This switching allows the conditioned air A1 to pass alternately through the first chamber 45 and the second chamber 46, making it possible to continuously and efficiently supply conditioned and humidified conditioned air A1 to multiple rooms 5.

[0103] Furthermore, by switching between the first state (shown in FIG. 7(a)) and the second state (shown in FIG. 7(b)), it is possible to pass outside air A3 (in this example, outside air with a high relative humidity) alternately through the first chamber 45 and the second chamber 46. This makes it possible to continuously restore the humidity conditioner 43 in the first chamber 45 and the second chamber 46.

[0104] In this way, in the house 2 of this embodiment, the humidity control device 15 is disposed in the air transport path to the living rooms 5, thereby enabling stable humidity control and air conditioning of the living rooms 5 (shown in FIG. 1). In order to stably control the humidity of the living rooms 5, it is preferable that the timing for switching between the first state and the second state be set to a predetermined time (for example, the time until most of the water vapor contained in the humidity control material 43 is released).

[0105] Furthermore, in this embodiment, by causing the conditioned air A1 and the outside air A3 to flow in a counterflow manner as described above, the difference in relative humidity between the first state and the second state is prevented from becoming uneven from one end 45a to the other end 45b of the first chamber 45. Furthermore, the difference in relative humidity between the first state and the second state is prevented from becoming uneven from one end 46a to the other end 46b of the second chamber 46. This allows the humidity control device 15 of this embodiment to fully utilize the moisture absorption and release performance of the humidity control material 43 in the first chamber 45 and the second chamber 46.

[0106] Furthermore, humidity control device 15 of the present embodiment can be switched between the first state and the second state simply by rotating humidity control unit 16 around the x-axis, and therefore does not require a damper as in Patent Document 1. Therefore, humidity control device 15 of the present embodiment can reduce the number of dampers and ease maintenance.

[0107] In the first state shown in FIG. 7(a), the first outlet 36A and the first chamber 45 (the space partitioned by the first partition 47, the second partition 48, the first side member 33A, and the second side member 33B) preferably form a straight flow path (indicated by the dashed line) along the z-axis. This reduces the pressure loss of the humidity-conditioned air A1 between the first chamber 45 and the first outlet 36A. Therefore, in the first state, the humidity-conditioned air A1 can be efficiently supplied to multiple rooms 5 (shown in FIG. 1).

[0108] Furthermore, in the first state, it is preferable that the first inlet 35A and the first chamber 45 form a straight flow path (shown by the dashed line in FIG. 7(a)) along the z-axis. This reduces the pressure loss of the conditioned air A1 between the first inlet 35A and the first chamber 45, and the conditioned air A1 is smoothly guided into the first chamber 45. Therefore, the humidity of the conditioned air A1 can be efficiently controlled.

[0109] In the first state, the second outlet 36B and the second chamber 46 (the space partitioned by the first partition 47, the third partition 49, the first side member 33A, and the second side member 33B) preferably form a straight flow path along the z-axis. This reduces the pressure loss of the outside air A3 used to restore the humidity control material 43 between the second chamber 46 and the second outlet 36B, allowing the outside air A3 to be efficiently supplied to the attic 39 (shown in FIG. 1).

[0110] 7(b), the first outlet 36A and the second chamber 46 preferably form a straight flow path (shown by the dashed line) along the z-axis. This allows the humidity-controlled conditioned air A1 to be efficiently supplied to multiple rooms 5 (shown in FIG. 1) in the second state.

[0111] Furthermore, in the second state, it is preferable that the first inlet 35A and the second chamber 46 form a straight flow path along the z-axis, which allows the conditioned air A1 to be smoothly guided to the second chamber 46 and allows the conditioned air A1 to be efficiently conditioned.

[0112] In the second state, the second outlet 36B and the first chamber 45 preferably form a straight flow path along the z-axis direction, which reduces the pressure loss of the outside air A3 used to restore the humidity control material 43 between the first chamber 45 and the second outlet 36B, allowing the outside air A3 to be efficiently supplied to the attic 39 (shown in FIG. 1).

[0113] In this embodiment, the humidity conditioner 43 in the first chamber 45 and the humidity conditioner 43 in the second chamber 46 are set so that the volume of the humidity conditioner 43 per unit length in the y-axis direction increases the closer they are to the rotation axis 51. This causes the centers of gravity of the humidity conditioners 43, 43 to be biased toward the rotation axis 51, thereby preventing the torque of the drive unit 28 from becoming too large.

[0114] Furthermore, since the volume of the humidity-regulating material 43 on the rotating shaft 51 side is set large, it is possible to maximize (expand) the volume of the humidity-regulating material 43 in the limited space within the casing 26 (sub-casing 27) while suppressing an increase in the torque of the drive unit 28.

[0115] On the other hand, the volume of the humidity control material 43 per unit length in the y-axis direction is set to be smaller the farther it is from the rotation axis 51, so the rotation radius R1 (shown in FIG. 6) of the humidity control unit 16 can be made smaller. This makes it possible to make the humidity control device 15 (casing 26) more compact.

[0116] Furthermore, the humidity control material 43 in the first chamber 45 and the humidity control material 43 in the second chamber 46 are configured with a plurality of humidity control elements 53 (in this example, first humidity control element 53A and second humidity control element 53B) that differ in length along the z axis. In this embodiment, of the first humidity control element 53A and the second humidity control element 53B, the first humidity control element 53A, which has a relatively long length along the z axis, is arranged closer to the rotation axis 51 of the humidity control unit 16. This allows the length of the humidity control material 43 along the z axis per unit length in the y axis direction of the humidity control material 43 to be increased closer to the rotation axis 51, and as a result, it becomes possible to easily increase the volume of the humidity control material 43 per unit length in the y axis direction of the humidity control material 43.

[0117] In this embodiment, the humidity control element 53 is fixed so as to be disassembled. This allows the humidity control material 43 to be easily removed from the casing 26 (sub-casing 27), improving maintainability. To improve such maintainability, it is preferable that each of the multiple humidity control elements 53 can be taken in and out through the opening 42 of the casing 26 (sub-casing 27). This improves maintainability of the humidity control material 43.

[0118] 8(a) and 8(b) are side views showing a state in which the multiple humidity control elements 53 of one chamber (first chamber 45) are removed from the opening 42. As shown in FIG. 8(a), the humidity control unit 16 shown in FIG. 6 is rotated 90 degrees, and the multiple humidity control elements 53 are arranged in the direction of the z-axis. As shown in FIG. 8(a), the second humidity control element 53B (shown by a two-dot chain line) of one chamber (in this example, the first chamber 45) of the first chamber 45 and the second chamber 46 is disposed on the opening 42 side of the casing 26 (sub-casing 27).

[0119] Next, after the opening 42 is opened, the second humidity control element 53B of one of the chambers (in this example, the first chamber 45) is removed from the opening 42. In this embodiment, the second partition 48 of the first chamber 45 is removed before the second humidity control element 53B is removed.

[0120] 8(b), the first humidity control element 53A of one of the chambers (in this example, the first chamber 45) is removed from the opening 42. This allows the first humidity control element 53A and the second humidity control element 53B of the one of the chambers (in this example, the first chamber 45) to be easily removed from the casing 26 (the sub-casing 27) and the main casing 12 (shown in FIG. 2).

[0121] 9(a) and 9(b) are side views showing a state in which the multiple humidity control elements 53 of the other chamber (second chamber 46) are being removed from the opening 42. As shown in FIG. 9(a), by rotating the humidity control unit 16 shown in FIG. 8(b) by 180 degrees, the second humidity control element 53B (shown by the two-dot chain line) of the other chamber (in this example, the second chamber 46) is positioned on the opening 42 side. In this embodiment, the center of gravity of the humidity control material 43 of the second chamber 46 is set so as to be biased toward the rotation axis 51 side. This makes it possible to rotate the humidity control unit 16 with a small torque, even when the humidity control material 43 (first humidity control element 53A and second humidity control element 53B) of one chamber (first chamber 45) is removed.

[0122] Next, the second humidity control element 53B of the other chamber (in this example, the second chamber 46) is removed from the opening 42. In this embodiment, the third partition 49 of the second chamber 46 is removed before the second humidity control element 53B is removed.

[0123] 9(b), the first humidity control element 53A of the other chamber (in this example, the second chamber 46) is removed from the opening 42. This allows the first humidity control element 53A and the second humidity control element 53B of the other chamber (in this example, the second chamber 46) to be easily removed from the casing 26 (sub-casing 27) and the main casing 12.

[0124] The humidity control element 53 (in this example, the first humidity control element 53A and the second humidity control element 53B) can be attached to the first chamber 45 and the second chamber 46 in the reverse order of the procedure for removing the humidity control element 53 shown in Figures 8 and 9.

[0125] In this way, in the humidity control device 15 (humidity control section 16) of this embodiment, the humidity control element 53 can be easily inserted and removed through the opening 42 provided in the casing 26 (sub-casing 27), thereby improving maintainability.

[0126] The humidity control device 15 (humidity control section 16) of this embodiment is disposed in an air conditioning / humidity control unit 10 that includes a main casing 12, an air conditioner 13, and an air pressure feeder 14. Therefore, unlike, for example, Patent Document 1, in which the air conditioner and the humidity control chamber are provided in separate locations, the air conditioning / humidity control unit 10 of this embodiment allows easy access to the air conditioner 13 and the humidity control device 15 (humidity control section 16), thereby improving maintainability.

[0127] Furthermore, in the air conditioning / humidity control unit 10 of this embodiment, as shown in Fig. 4, an air flow directed from the inlet 22 to the outlet 23 of the main casing 12 is generated by the air compressor 14 arranged in the internal flow path 24. As a result, conditioned air A1 from the air conditioner 13 is directly supplied to the humidity control device 15 (humidity control section 16) within the main casing 12. Therefore, in the air conditioning / humidity control unit 10 of this embodiment, changes in the temperature and relative humidity of the conditioned air A1 are suppressed before the conditioned air A1 is supplied to the humidity control device 15 (humidity control section 16), improving the air conditioning efficiency and humidity control efficiency.

[0128] In the present embodiment, an example has been given in which the living room 5 (shown in FIG. 1) is humidified in winter, but the present invention is not limited to such an example. For example, the living room 5 may be dehumidified in summer. In this case, by supplying conditioned air A1 having a high relative humidity (cooled) to one of the first chamber 45 and the second chamber 46 of the humidity control unit 16, water vapor contained in the conditioned air A1 can be adsorbed to the humidity control material 43. Furthermore, by supplying outside air A3 having a low relative humidity to the other of the first chamber 45 and the second chamber 46, water vapor adsorbed to the humidity control material 43 is released, and the dehumidifying capacity can be restored.

[0129] [Humidity control device (second embodiment)] As shown in Figures 5 and 6, in the first humidity control element 53A and the second humidity control element 53B of the previous embodiments, one end 53a and the other end 53b in the z-axis direction are formed in a planar shape perpendicular to the z-axis (a planar shape extending from the x-axis to the y-axis), but this is not limited to this. For example, the one end 53a and the other end 53b may be formed in a planar shape (a sloping surface) that intersects with the plane perpendicular to the z-axis. Figure 10 is a cross-sectional view showing a humidity control material 43 of another embodiment of the present invention.

[0130] In this embodiment, one end 53a and the other end 53b of the humidity control element 53 are formed at an angle with respect to a plane perpendicular to the z axis so that the length along the z axis of the humidity control material 43 per unit length in the y axis direction of the humidity control material 43 increases the closer to the rotation axis 51. This causes the center of gravity of the humidity control material 43 to be biased toward the rotation axis 51, making it possible to reduce the torque of the drive unit 28. Furthermore, the humidity control element 53 can reduce friction with the conditioned air A1 or outside air A3 supplied to one end 53a or the other end 53b, thereby reducing pressure loss.

[0131] Furthermore, the humidity control material 43 in the first chamber 45 and the humidity control material 43 in the second chamber 46 may have an arc-shaped outer circumferential surface that follows the circle of rotation indicated by the two-dot chain line in Fig. 6. This makes it possible to maximize (expand) the volume of the humidity control material 43 within the limited space inside the casing 26 (sub-casing 27).

[0132] [Humidity control device (third embodiment)] As shown in Figures 6 and 10, the humidity control material 43 in the embodiments described above is composed of multiple humidity control elements 53 (first humidity control element 53A, second humidity control element 53B), but is not limited to this. For example, the humidity control material 43 may be composed of only one humidity control element 53 (not shown). Such a humidity control material 43 can reduce manufacturing costs compared to when it is composed of multiple humidity control elements 53.

[0133] [Humidity control device (fourth embodiment)] As shown in FIGS. 1 and 4 , the humidity control device 15 in the above-described embodiments is disposed in an air conditioning / humidity control unit 10 including a main casing 12, an air conditioner 13, and an air compressor 14. However, the present invention is not limited to this configuration. The humidity control device 15 (casing 26) may be disposed in a location (e.g., an attic 39) separate from the main casing 12 in which the air conditioner 13 is disposed. In this case, for example, a duct capable of supplying conditioned air A1 is provided between the main casing 12 and the humidity control device 15. This allows the humidity control unit 10 to be installed anywhere within the house 2, thereby preventing the air conditioning / humidity control unit 10 (main casing 12) from becoming larger. In this case, the conditioned air A1 is preferably supplied to the humidity control device 15 via an air flow path (not shown) extending between the main casing 12 and the casing 26 (sub-casing 27).

[0134] Although a particularly preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the illustrated embodiment and can be modified and implemented in various ways. [Explanation of symbols]
