Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in order to alternately supply air to the two chambers, a plurality of dampers are required, and there is a problem that maintenance of these is difficult.

[0005] Also, a desiccant rotor type humidity control system is known. In this humidity control system, although a plurality of dampers as described above are not required, there is a problem that the amount of air leakage in the constantly rotating rotor part increases and the humidity control efficiency decreases.

[0006] The present invention has been devised in view of the above actual situation, and the main object is to provide a humidity control device and the like that can improve maintainability and humidity control efficiency.

Means for Solving the Problems

[0007] The present invention relates to a batch-type humidity control device for humidifying air, comprising a casing, a humidity control unit rotatably disposed within the casing, an air transport unit for passing the air through the casing, and a drive unit for rotating the humidity control unit, wherein, in a Cartesian coordinate system of x, y, and z, the humidity control unit comprises a first partition extending in the direction of the z axis, a first chamber and a second chamber separated side by side in the direction of the y axis via the first partition, and a humidity control material provided inside the first chamber and the second chamber for humidifying the air passing through in the direction of the z axis, and the casing comprises the first partition and extending in the direction of the z axis through gaps from both ends of the first partition The device is a humidity control device that, by a second partition, divides the chamber into a first space and a second space, which are arranged side by side in the y-axis direction and through which the air passes in the z-axis direction. The drive unit rotates the humidity control unit around a rotation axis extending in the x-axis direction, thereby alternately switching between a first state in which the first chamber is located in the first space and the second chamber is located in the second space, and a second state in which the first chamber is located in the second space and the second chamber is located in the first space. The air transport unit passes the air through the first space and the second space so that both the first chamber and the second chamber are under positive pressure or both are under negative pressure. [Effects of the Invention]

[0008] By adopting the above configuration, the humidity control device of the present invention can improve both maintainability and humidity control efficiency. [Brief explanation of the drawing]

[0010] Embodiments of the present invention will be described below with reference to the drawings. It should be understood that the drawings contain exaggerations and representations that differ from the actual dimensional ratios of the structures in order to aid in understanding the content of the invention. Furthermore, the same or common elements are denoted by the same reference numerals throughout each embodiment, and redundant explanations are omitted. Moreover, the specific configurations shown in the embodiments and drawings are for the purpose of understanding the content of the present invention, and the present invention is not limited to the specific configurations shown in the drawings.

[0011] The humidity control device of this embodiment is for controlling the humidity of the air. The humidity control device of this embodiment is configured as a batch-type humidity control device that can alternately repeat the process of releasing and absorbing moisture at a predetermined cycle.

[0012] The humidity control device of this embodiment is installed in a house, for example, together with an air conditioner. In this embodiment, the humidity control device is interposed in the air transport path to the living room within a whole-house air conditioning system that includes an air conditioner.

[0013] [Housing] Figure 1 is a conceptual cross-sectional view of a house 2 equipped with a humidity control device and an air conditioner according to this embodiment. The house 2 of this embodiment is configured to include, for example, an underfloor space 3 and an above-floor space 4.

[0014] In the floor space 4 of the present embodiment, for example, a plurality of living rooms 5 are provided. The living rooms 5 include the living rooms on the first floor, but may also include the living rooms on the second floor and above (not shown). Further, each living room 5 is partitioned, for example, by a door 6 or the like, and air A2 flows through a gap 7 formed in the door 6.

[0015] [Whole-building air-conditioning system] The whole-building air-conditioning system 1 of the present embodiment is for humidifying the air (hereinafter sometimes simply referred to as "conditioned air") A1 air-conditioned by the air conditioner 13 and supplying it to a plurality of living rooms 5.

[0016] The whole-building air-conditioning system of the present embodiment includes an air-conditioning and humidifying device 10 and a first flow path 11. The first flow path 11 of the present embodiment is connected between the air-conditioning and humidifying device 10 and a plurality of living rooms 5. Thereby, the first flow path can supply the conditioned air (humidified conditioned air) A1 from the air-conditioning and humidifying device 10 to a plurality of living rooms 5. Further, the first flow path 11 of the present embodiment can be set as appropriate as long as it can supply the conditioned air A1 to a plurality of living rooms 5. The first flow path 11 of the present embodiment is formed by a duct formed in a cylindrical shape, but may be configured by, for example, a space surrounded by a partition wall (not shown).

[0017] [Air-conditioning and humidifying device] The air-conditioning and humidifying device 10 of the present embodiment includes a main casing 12, an air conditioner 13, and a filter member 17. Further, the air-conditioning and humidifying device 10 of the present embodiment includes the above-described humidifying device 15. Note that the humidifying device 15 may be configured independently of the air-conditioning and humidifying device 10. FIG. is a perspective view showing the main casing 12 of the air-conditioning and humidifying device 10 including the humidifying device 15 of the present embodiment. FIG. 3 is a partial perspective view of FIG. FIG. 4 is a partial cross-sectional view of FIG. In the present embodiment, the positions of the respective constituent members of the air-conditioning and humidifying device 10 are specified on a rectangular coordinate system of an x-axis, a y-axis, and a z-axis orthogonal to the x-axis and the y-axis. Also, in the present embodiment, the directions of the x-axis and the y-axis are set as the horizontal directions, and the direction of the z-axis is set as the vertical direction (height direction), but the present invention is not limited to such an aspect.

[0018] [Main casing] As shown in FIGS. 2 and 3, the main casing <12> of the present embodiment is formed in a box shape having a main space (main space) <18> inside. The main space <18> of the present embodiment is divided by a frame body <19> and a facing material <20> supported by the frame body <19>. The facing material <20> may include, for example, a heat insulating material (not shown) for insulating the inside of the main space <18> and the outside of the main casing <12>.

[0019] As shown in FIGS. 3 and 4, the main space <18> of the present embodiment is divided into a first main space <18A>, a second main space <18B>, and a third main space <18C> by a first partition facing material <20A> (including a first side facing material <33A> to be described later) provided in the main casing <12>. The first partition facing material <20A> (first side facing material <33A>) of the present embodiment is disposed substantially at the center in the x-axis direction in the main casing <12>. Thereby, the first main space <18A> and the second main space <18B> are adjacent to each other in the x-axis direction via the first partition facing material <20A> (first side facing material <33A>).

[0020] The first partition facing material <20A> (first side facing material <33A>) of the present embodiment extends from one end (in this example, the upper end) to the other end (in this example, the lower end) side of the main casing <12> in the z-axis direction and terminates without reaching the other end. Thereby, a third main space <18C> communicating with the first main space <18A> and the second main space <18B> is divided on the other end side of the first partition facing material <20A> (first side facing material <33A>) in the main space <18>.

[0021] As shown in FIGS. 2 and 3, an openable and closable door portion <21> is provided in the main casing <12> of the present embodiment. When such a door portion <21> is opened, it becomes possible to easily access the main space (main space) <18> inside the main casing <12>. Therefore, the maintainability of the air conditioning and humidity control device <10> is improved. The door portion 21 of the present embodiment is configured to include a first door portion <21A> and a second door portion <21B>. These first door portion <21A> and second door portion <21B> are arranged in the z-axis direction (in this example, the vertical direction) z, but are not particularly limited.

[0022] As shown in Figures 2 to 4, the main casing 12 of this embodiment includes at least one inlet 22, at least one outlet 23, and an internal flow path 24 (shown in Figure 4) that connects the inlet 22 and the outlet 23.

[0023] The inlet 22 in this embodiment is for supplying air to the main space 18 of the main casing 12. The inlet 22 in this embodiment is formed as a hole that connects the outside of the main casing 12 (in this example, the floor space 4 shown in Figure 1) with the main space 18 of the main casing 12.

[0024] In this embodiment, the inlet 22 is provided on one end (upper end) side of the main casing 12 in the z-axis direction. Furthermore, the inlet 22 is provided on one side (first main space 18A) of the first partition surface material 20A in the x-axis direction. As a result, the inlet 22 can supply air (in this example, air A2 inside the house 2) to the first main space 18A.

[0025] In this embodiment, the inlet 22 is formed to supply air A2 from inside the house 2 (in this example, return air from multiple living rooms 5) to the main space 18 of the main casing 12, but the embodiment is not limited to this configuration. The inlet 22 may be formed to supply, for example, outside air for ventilation (not shown). In addition, multiple inlets 22 may be provided so that the air A2 from inside the house 2 and the outside air for ventilation can be supplied independently.

[0026] The outlet 23 in this embodiment is for supplying, for example, conditioned air (in this example, humidified conditioned air) A1 from the main 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 main space 18 of the main casing 12 to the outside of the main casing 12 (in this example, the first flow path 11).

[0027] In this embodiment, the outlet 23 is provided on one end (upper end) side of the main casing 12 in the z-axis direction. Furthermore, the outlet 23 is provided on the other side (second main space 18B) of the first partition surface material 20A in the x-axis direction. This makes it possible for the outlet 23 to extract air from the second main space 18B and supply it to the outside of the main casing 12 (in this example, the first flow path 11).

[0028] In this embodiment, the outlet 23 is connected to the first flow path 11 described above. As a result, the air (conditioned air A1) from the second main space 18B can be supplied from the outlet 23 to multiple living rooms 5 (shown in Figure 1) via the first flow path 11.

[0029] As shown in Figure 4, the internal flow path 24 of this embodiment connects the inlet 22 and the outlet 23. As a result, the internal flow path 24 of this embodiment can conditioned the air (return air in this example) A2 supplied from the inlet 22 by the air conditioner 13, and guide the conditioned air A1 to the outlet 23 (first flow path 11).

[0030] In this embodiment, the internal flow path 24 is composed of a first main space 18A communicating with the inlet 22, a second main space 18B communicating with the outlet 23, and a third main space 18C connecting the first main space 18A and the second main space 18B. As a result, the internal flow path 24 is formed in a U-shape when viewed from the side in the direction of the y-axis.

[0031] [Air conditioner] As shown in Figures 3 and 4, the air conditioner 13 of this embodiment is composed of, for example, a typical household split-type air conditioner. The air conditioner 13 includes an indoor unit 13A and an outdoor unit (not shown) installed outside the house 2 as a set. The indoor unit 13A has an intake port 13a and an outlet port 13b.

[0032] In this embodiment, the air conditioner 13 (indoor unit 13A) is located in the internal flow path 24 of the main casing 12. In this embodiment, the indoor unit 13A is located in the first main space 18A (inlet 22 side) of the internal flow path 24.

[0033] In this embodiment, the intake port 13a takes in air A2 supplied from the inlet 22 (in this example, air from inside the house 2 (return air)) and supplies it to a heat exchanger (not shown) located inside the indoor unit 13A. On the other hand, the outlet port 13b in this embodiment discharges the air A1 conditioned by the heat exchanger (conditioned air) to the outlet 23 side (downstream side of the internal flow path 24 (third main space 18C and second main space 18B side)).

[0034] The set temperature and airflow (discharge airflow) of the air conditioner 13 are controlled, for example, by a control device 25 (shown in Figure 1). In this embodiment, the control device 25 is installed, for example, in a partition wall of a living room 5, but is not limited to this configuration. The control device 25 is configured as a computer including a calculation unit (not shown) consisting of a CPU (Central Processing Unit), a storage unit (not shown) in which control procedures are pre-stored, and a working memory (not shown) for reading control procedures from the storage unit.

[0035] [Filter components] The filter member 17 in this embodiment is for purifying the air. The filter member 17 in this embodiment is arranged in the internal flow path 24 of the main casing 12. With such a filter member 17, the air in the internal flow path 24 can be purified.

[0036] In this embodiment, the filter member 17 is located in the internal flow path 24 between the air conditioner 13 and the humidity control device 15, which will be described later. As a result, the conditioned air A1 purified by the filter member 17 is supplied to the humidity control device 15, thereby suppressing contamination of the humidity control device 15.

[0037] The filter component 17 is not particularly limited as long as it can purify the air. Examples of the filter component 17 include a HEPA (High Efficiency Particulate Air) filter, a photocatalytic filter, an activated carbon deodorizing filter, or an electrostatic precipitator filter, which may be arranged individually or in combination.

[0038] [Humidity control device] As shown in Figure 4, the humidity control device 15 of this embodiment is located in the internal flow path 24 of the main casing 12 and on the outlet 23 side of the air conditioner 13. With such a humidity control device 15, the conditioned air A1 of the air conditioner 13 can be humidified.

[0039] The location of the humidity control device 15 in this embodiment is not particularly limited, as long as it is located within the internal flow path 24 of the main casing 12 and on the outlet 23 side (downstream side of the internal flow path 24) of the air conditioner 13. The humidity control device 15 (humidity control unit 16) in this embodiment is provided in the second main space 18B.

[0040] As shown in Figures 2 to 4, the humidity control device 15 of this embodiment is composed of a casing 26, a humidity control unit 16, an air transport unit 14, and a drive unit 28.

[0041] [Casing (Secondary Casing)] In this embodiment, the casing 26 is configured as a sub-casing 27 within the main casing 12, in which the humidity control unit 16 is placed inside. As shown in Figure 4, the casing 26 in this embodiment is formed in a box shape having a sub-space 29 inside.

[0042] In this embodiment, the casing 26 is fixed to the main casing 12 in a way that allows for disassembly. This improves the maintainability of the humidity control device 15. Alternatively, the casing 26 may be integrally constructed with the main casing 12 (fixed in a way that prevents disassembly). Figure 5 is an exploded perspective view of the humidity control device 15 excluding the air conveying section 14. Figure 6 is a cross-sectional view of the humidity control device 15 excluding the air conveying section 14.

[0043] As shown in Figures 4 to 6, the casing 26 of this embodiment is composed of a bottom material 31 and an top material 32 arranged on both sides in the direction of the z axis, and a plurality of side materials 33 arranged between the bottom material 31 and the top material 32. These bottom material 31, top material 32 and plurality of side materials 33 divide the casing 26 into a subspace 29.

[0044] Each of the bottom material 31, top material 32, and multiple side material 33 in this embodiment is formed in a rectangular shape in plan view. As a result, the casing 26 is formed in a rectangular shape in plan view from the x, y, and z axes. These bottom material 31, top material 32, and multiple side material 33 may include thermal insulation material (not shown).

[0045] As shown in Figure 5, the bottom material 31 and top material 32 of this embodiment are spread out in the x-axis-y-axis plane. These bottom material 31 and top material 32 are spaced apart from each other in the z-axis direction.

[0046] As shown in Figures 4 to 6, the multiple side members 33 of this embodiment are composed of a first side member 33A, a second side member 33B, a third side member 33C, and a fourth side member 33D.

[0047] The first side member 33A and the second side member 33B of this embodiment extend in the y-z axis plane. These first side member 33A and the second side member 33B are spaced apart from each other in the x-axis direction. As shown in Figure 4, the first side member 33A of this embodiment is fixed to the first partition surface member 20A of the main casing 12, but the embodiment is not limited to this configuration.

[0048] As shown in Figure 5, the third side member 33C and the fourth side member 33D of this embodiment extend in the x-axis-z-axis plane. These third side member 33C and fourth side member 33D are spaced apart from each other in the direction of the y-axis.

[0049] As shown in Figures 5 and 6, the casing 26 of this embodiment is provided with a second partition 34. Figure 8 shows a partially enlarged view of Figure 4 (cross-sectional view of the humidity control device 15). As shown in Figures 5, 6, and 8, the second partition 34 extends in the z-axis direction from both ends (in this example, both ends in the z-axis direction) 50, 50 of the first partition 30, which will be described later and extends in the z-axis direction, via a gap 44. The second partition 34 of this embodiment is formed in the shape of a plate that spreads in the x-axis-z-axis plane. Furthermore, the second partition 34 is positioned between the third side material 33C and the fourth side material 33D in the y-axis direction. With these first partition 30 and second partition 34, the casing 26 (sub-space 29) is divided into a first space 29A and a second space 29B, which are arranged side by side in the y-axis direction and allow air to pass in the z-axis direction.

[0050] The casing 26 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.

[0051] The first inlet 35A in this embodiment is for supplying air to the first space 29A. This first inlet 35A is formed in the bottom material 31. On the other hand, the second inlet 35B in this embodiment is for supplying air to the second space 29B. This second inlet 35B is formed in the fourth side material 33D. Note that the positions of the first inlet 35A and the second inlet 35B are not limited to this configuration.

[0052] In this embodiment, the first outlet 36A is for drawing air from the first space 29A. On the other hand, the second outlet 36B is for drawing air from the second space 29B. These first outlets 36A and the second outlets 36B are formed in the top material 32. Note that the positions of the first outlet 36A and the second outlet 36B are not limited to this configuration.

[0053] As shown in Figure 5, the first inlet 35A and the first outlet 36A in this embodiment are provided on one side of the casing 26 in the direction of the y-axis (in this example, one side relative to the first partition 30 and the second partition 34 (the side of the first space 29A)). As a result, the first inlet 35A and the first outlet 36A can communicate with the first space 29A and the outside of the casing 26.

[0054] As shown in Figure 4, the first inlet 35A of this embodiment is in communication with the third main space 18C of the main casing 12. This allows the first inlet 35A to supply conditioned air A1 from the third main space 18C to the first space 29A (second main space 18B). On the other hand, the first outlet 36A of this embodiment is the outlet 23 of the main casing 12 described above.

[0055] As shown in Figure 5, the second inlet 35B and the second outlet 36B in this embodiment are located on the other side of the casing 26 in the direction of the y-axis (in this example, on the other side of the first partition 30 and the second partition 34 (towards the second space 29B)). This allows the second inlet 35B and the second outlet 36B to communicate with the second space 29B and the outside of the casing 26.

[0056] As shown in Figures 5 and 6, the second inlet 35B in this embodiment is connected to an outside air supply unit 37 for supplying outside air A3. As a result, the second inlet 35B can supply outside air A3 to the second space 29B (second main space 18B).

[0057] The outside air supply unit 37 of this embodiment is configured to include a second flow path 38. As shown in Figure 1, one end of the second flow path 38 is located in the attic 39 of the house 2. Outside air A3, which is used to restore (regenerate) the humidity control material 43 (humidity control element 53) described later, is supplied to this attic 39. On the other hand, as shown in Figure 5, the other end of the second flow path 38 is connected to the second inlet 35B. The second flow path 38 of this embodiment is formed by a cylindrical duct, but is not particularly limited. The second flow path 38 may be configured, for example, in a space enclosed by a partition wall (not shown).

[0058] As shown in Figures 5 and 6, one end of the third channel 41 is connected to the second outlet 36B in this embodiment. The other end of the third channel 41 is located in the attic 39, as shown in Figure 1. Therefore, the outside air A3 from the second space 29B can be supplied to the attic 39 (shown in Figure 1) via the second outlet 36B and the third channel 41.

[0059] As shown in Figures 3 to 5, it is preferable that the casing 26 of this embodiment is provided with an openable and closable inspection door 42. When such an inspection door 42 is opened, the inside of the casing 26 (in this example, the humidity control section 16 (humidity control material 43) described later) can be easily accessed, improving maintainability.

[0060] The inspection door 42 can be appropriately configured as long as it allows the casing 26 to be opened and closed. As shown in Figures 3 and 4, the inspection door 42 in this embodiment is provided on the lower side of the first side member 33A as part of the first side member 33A, and is configured as a door that can rotate around the y-axis. Therefore, for example, the inspection door 42 can be opened from outside the main casing 12 by opening the door portion 21 (shown in Figure 2) and removing the filter member 17. This makes it possible to easily access the inside of the casing 26.

[0061] [Humidity control section] As shown in Figures 5 and 6, the humidity control unit 16 of this embodiment comprises a first partition 30, a first chamber 45 and a second chamber 46, and a humidity control material 43.

[0062] [First partition section] The first partition portion 30 in this embodiment extends in the direction of the z axis. The first partition portion 30 in this embodiment is formed in a plate shape that extends in the plane of the x axis-z axis. Together with the second partition portion 34, this first partition portion 30 divides the casing 26 into a first space 29A and a second space 29B. In this embodiment, both ends 55, 55 in the x-axis direction of the first partition 30 are adjacent to the first side material 33A and the second side material 33B, with a gap 58 (shown in Figure 8) in between.

[0063] [First Chamber, Second Chamber] The first chamber 45 and the second chamber 46 are separated by a first partition 30, aligned in the direction of the y-axis. In this embodiment, the first chamber 45 is positioned on one side in the direction of the y-axis with respect to the rotation axis 51 which extends in the direction of the x-axis. On the other hand, the second chamber 46 in this embodiment is positioned on the other side in the direction of the y-axis with respect to the rotation axis 51.

[0064] In this embodiment, the first chamber 45 is divided by a first partition 30, a third partition 48, the first side material 33A described above, and the second side material 33B described above. However, the first chamber 45 is not limited to this configuration and may be divided by other partitions (not shown), for example. A humidity control material 43 is provided inside the first chamber 45.

[0065] The third partition 48 in this embodiment is formed in a plate shape that extends in the x-axis-z-axis plane, similar to the first partition 30. This third partition 48 is fixed to the first partition 30, for example, via a connecting part (not shown). Furthermore, both ends 56, 56 (shown in Figure 5) of the third partition 48 in the x-axis direction are adjacent to the first side material 33A and the second side material 33B via a gap 58 (shown in Figure 8), similar to the first partition 30.

[0066] In this embodiment, the second chamber 46 is divided by the first partition 30, the fourth partition 49, the first side material 33A described above, and the second side material 33B described above. The first chamber 45 is not limited to this configuration and may be divided by other partitions (not shown), for example. A humidity control material 43 is provided inside the second chamber 46.

[0067] The fourth partition 49 in this embodiment is formed in a plate shape that extends in the x-axis-z-axis plane, similar to the first partition 30 and the third partition 48. This fourth partition 49 is fixed to the first partition 30, for example, via a connecting part (not shown). Furthermore, both ends 57, 57 (shown in Figure 5) of the fourth partition 49 in the x-axis direction are adjacent to the first side material 33A and the second side material 33B via a gap 58 (shown in Figure 8), similar to the first partition 30.

[0068] As shown in Figures 5 and 6, the first chamber 45 and the second chamber 46 of this embodiment are open at both ends in the longitudinal direction (z-axis direction) of the first partition 30, the third partition 48, and the fourth partition 49. This allows air to pass through the first chamber 45 and the second chamber 46 along the z-axis direction (vertical direction).

[0069] In order to efficiently allow air to pass through the first chamber 45 and the second chamber 46 (humidifying material 43), it is preferable that the casing 26 be provided with, for example, a fifth partition 52. The fifth partition 52 in this embodiment is formed in the shape of a plate that extends in the x-axis-y-axis plane and extends between the third partition 48 and the third side material 33C, and between the fourth partition 49 and the fourth side material 33D. Such a fifth partition 52 can seal the gap between the third partition 48 and the third side material 33C, and the gap between the fourth partition 49 and the fourth side material 33D, making it possible to prevent air from entering these gaps.

[0070] [Humidity control material] The humidity control material 43 is provided inside the first chamber 45 and the second chamber 46, and is for regulating the humidity of the air passing through in the z-axis direction. The humidity control material 43 of this embodiment has the ability to adsorb water vapor from air with high relative humidity and to release the water vapor it has adsorbed to air with low relative humidity.

[0071] The humidity control material 43 is not particularly limited as long as it has moisture absorption and release properties. In this embodiment, the humidity control material 43 is composed of humidity control elements 53.

[0072] As shown in Figure 5, the humidity control element 53 of this embodiment is composed of a plurality of humidity control sheets 54. The plurality of humidity control sheets 54 are stacked with gaps between them (for example, in a honeycomb or tiered pattern) so that air can pass through in the z-axis direction. Such a humidity control element 53 makes it possible to effectively increase the humidity exchange area. The humidity control sheets 54 are supported with an adsorbent material (not shown) similar to that described in Patent Document 1.

[0073] Each humidity control material 43 in this embodiment is composed of a plurality of divisible humidity control elements 53. For example, the humidity control material 43 provided inside the first chamber 45 includes a first humidity control element 53A and a second humidity control element 53B adjacent to the first humidity control element 53A in the y-axis direction. On the other hand, the humidity control material 43 provided in the second chamber 46 includes a first humidity control element 53C and a second humidity control element 53D adjacent to this first humidity control element 53C in the y-axis direction. The first humidity control elements 53A and 53C are provided on the side of the rotation axis 51.

[0074] The humidity control elements 53A to 53D in this embodiment are formed to have the same shape. This reduces the manufacturing cost of the humidity control elements 53A to 53D. However, the humidity control elements 53A to 53D may have different shapes.

[0075] As shown in Figures 4 to 6, the humidity control unit 16 of this embodiment is rotatably arranged within the casing 26. For example, the humidity control unit 16 of this embodiment is rotatably arranged within the casing 26 around a rotation axis 51 extending in the x-axis direction.

[0076] One end of the rotating shaft 51 in this embodiment is connected to the drive unit 28, which will be described later. As shown in Figure 4, the other end of the rotating shaft 51 is supported by a bearing (not shown) provided on the second side material 33B. This allows the humidity control unit 16 in this embodiment to rotate around the rotating shaft 51.

[0077] [Air Conveying Section] As shown in Figure 1, the air conveying unit 14 is for passing air into the casing 26. This air conveying unit 14 passes air through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are under positive pressure or both are under negative pressure. In this embodiment, an example is given in which air is passed through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are under positive pressure. The air conveying unit 14 includes a first fan 14A and a second fan 40.

[0078] As shown in Figures 1 to 4, the first fan 14A in this embodiment is for supplying air to the first inlet 35A. This first fan 14A is located in the internal flow path 24 of the main casing 12, between the air conditioner 13 and the humidity control unit 16 (in this example, the third main space 18C (shown in Figure 4)).

[0079] In this embodiment, the first fan 14A generates an airflow from the inlet 22 of the main casing 12 toward the outlet 23 (first outlet 36A of the casing 26). As a result, the first fan 14A can pass air through the first space 29A such that the first chamber 45 becomes positively pressurized relative to the outside of the humidity control unit 16. Through this airflow, air (return air) A2 from inside the house 2 is taken in from the inlet 22 and conditioned by the air conditioner 13. Furthermore, the airflow can smoothly guide the conditioned air A1 discharged from the air conditioner 13 through the casing 26 toward the outlet 23 (first outlet 36A).

[0080] As shown in Figure 1, the second fan 40 in this embodiment is for supplying air to the second space 29B of the casing 26. This second fan 40 is positioned in the second flow path 38 and generates an airflow from one end (the attic 39 side) to the other end (the second inlet 35B side of the casing 26). As a result, the second fan 40 can pass air through the second space 29B such that the second chamber 46 becomes positively pressurized relative to the outside of the humidity control unit 16. With this airflow, outside air A3 can be taken in from the second inlet 35B and guided smoothly through the casing 26 to the second outlet 36B. Note that the second fan 40 is not limited to being positioned in the second flow path 38 as long as it can make the second chamber 46 positively pressurized relative to the outside of the humidity control unit 16; for example, it may be positioned between the second inlet 35B and the humidity control unit 16.

[0081] In this embodiment, the first fan 14A and the second fan 40 are each composed of one unit, but this is not limited to this as long as they can generate the airflow described above. For example, the first fan 14A and the second fan 40 may each be composed of multiple units.

[0082] [Drive unit] As shown in Figures 4 and 5, the drive unit 28 is for rotating the humidity control unit 16. In this embodiment, the drive unit 28 rotates the humidity control unit 16 around a rotation axis 51 that extends in the x-axis direction within the casing 26.

[0083] The drive unit 28 is not particularly limited as long as it can rotate the humidity control unit 16. In this embodiment, the drive unit 28 is configured, for example, as a rotationally driven electric motor and is connected to the rotating shaft 51. This allows the humidity control unit 16 to be rotated. In Figure 6, the rotational trajectory of the humidity control unit 16 is shown by a dashed line.

[0084] 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 main space 18A. This allows for easy access to the drive unit 28 from the door portion 21 provided in the main casing 12 via the first main space 18A, improving maintainability.

[0085] In this embodiment, the drive unit 28 alternately switches between a first state and a second state by rotating the humidity control unit 16 around a rotation axis 51 extending in the x-axis direction. In this embodiment, for example, the humidity control unit 16 is switched between the first state and the second state by rotating the humidity control unit 16 approximately 180 degrees around the rotation axis 51. The above "approximately 180 degrees" is intended to allow for an error in the rotation accuracy of the drive unit 28, with a range of ±5 degrees being acceptable.

[0086] Figure 7(a) is a cross-sectional view showing the first state. Figure 7(b) is a cross-sectional view showing the second state. In Figure 7, the humidity control material 43 in the first chamber 45 and the humidity control material 43 in the second chamber 46 are colored to make them easier to distinguish. Furthermore, the outside air A3 in Figure 7 is colored.

[0087] In this embodiment, the control device 25 controls the drive unit 28, thereby switching the humidity control unit 16 alternately between a first state and a second state.

[0088] [First state] As shown in Figure 7(a), the first state is one in which the first chamber 45 is placed in the first space 29A and the second chamber 46 is placed in the second space 29B. In the first state of this embodiment, conditioned air A1 from the first inlet 35A flows through the first chamber 45 to the first outlet 36A. Furthermore, outside air A3 from the second inlet 35B flows through the second chamber 46 to the second outlet 36B.

[0089] In the first state, the first inlet 35A is supplied with conditioned air A1 from the air conditioner 13 (shown in Figure 4). For example, in winter, when the air conditioner 13 is operating in heating mode, the relative humidity of the conditioned air (heated conditioned air) A1 becomes low. As this conditioned air A1 with 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 on the humidity control material 43 (humidity control element 53) of the first chamber 45 is released (humidification state). As a result, the relative humidity of the conditioned air A1 is increased.

[0090] In the first state of this embodiment, the relative humidity of the air in the first chamber 45 (conditioned air A1) gradually increases from one end 45a to the other end 45b of the first chamber 45 due to the release of water vapor from the humidity control material 43 (humidity control element 53). The conditioned air A1, with its increased relative humidity (having passed through the other end 45b of the first chamber 45), is then supplied to multiple living rooms 5 (shown in Figure 1) via the first outlet 36A and the first flow path 11. As a result, in the first state, multiple living rooms 5 can be heated and effectively humidified.

[0091] Meanwhile, in the first state, outside air A3 is supplied to the second inlet 35B from the outside air supply unit 37. For example, outside air A3 in winter has a higher relative humidity than outside air in summer (not shown). As this outside air A3 with 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 onto the humidity control material 43 (humidity control element 53) of the second chamber 46 (humidity absorption state). This makes it possible to restore the humidification 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 the adsorption of water vapor onto the humidity control material 43 (humidity control element 53). The outside air A3, whose relative humidity has decreased (having passed through the other end 46b of the second chamber 46), is then supplied to the attic 39 (shown in Figure 1) via the third flow path 41 from the second outlet 36B. 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 Figure 7(b), the second state is a state in which the humidity control unit 16 has been rotated approximately 180 degrees around the rotation axis 51 from the first state. In this second state, the first chamber 45 is located in the second space 29B, and the second chamber 46 is located in the first space 29A. In the second state of this embodiment, conditioned air A1 from the first inlet 35A flows through the second chamber 46 to the first outlet 36A, and outside air A3 from the second inlet 35B flows through the first chamber 45 to the second outlet.

[0094] In the second state, the first inlet 35A is supplied with conditioned air A1 from the air conditioner 13 (in this example, conditioned air with low relative humidity). As this conditioned air A1 with low relative humidity passes from the other end 46b to the first end 46a of the second chamber 46, the water vapor adsorbed by the humidity control material 43 in the second chamber 46 is released (humidification state). This increases the relative humidity of the conditioned air A1.

[0095] In the second state of this embodiment, the relative humidity of the air in the second chamber 46 (conditioned air A1) gradually increases from the other end 46b to the first 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 first end 46a of the second chamber 46) is supplied from the first outlet 36A to the multiple living rooms 5 (shown in Figure 1) via the first flow path 11. As a result, in the second state, as in the first state, multiple living rooms 5 can be heated and effectively humidified.

[0096] In the second state, the flow of conditioned air A1 in the second chamber 46 (flow from the other end 46b to the other end 46a) is in the opposite direction to the flow of outside air A3 in the second chamber 46 in the first state shown in Figure 7(a) (i.e., it becomes a counterflow). This suppresses the bias in the difference in relative humidity between the first state (shown in Figure 7(a)) and the second state (shown in Figure 7(b)) from the one end 46a side to the other end 46b side of the second chamber 46 (i.e., it makes the difference in relative humidity closer to uniform). Therefore, the humidity control device 15 of this embodiment makes it possible to utilize the moisture absorption and release performance of the humidity control material 43 throughout the second chamber 46, from the one end 46a side to the other end 46b side.

[0097] In the second state, outside air (in this example, outside air with high relative humidity) A3 from the outside air supply unit 37 is supplied to the second inlet 35B. As this outside air A3 with high relative humidity passes from the other end 45b to the first end 45a of the first chamber 45, the water vapor contained in the outside air A3 can be adsorbed by the humidity control material 43 of the first chamber 45 (humidification state). This makes it possible to restore the humidification capacity of the humidity control material 43.

[0098] In the second state of this embodiment, the relative humidity of the air (outside air A3) inside the first chamber 45 gradually decreases from the other end 45b to the first end 45a of the first chamber 45 due to the adsorption of water vapor onto the humidity control material 43 (humidity control element 53). The outside air A3, whose relative humidity has decreased (having passed through the first end 45a of the first chamber 45), is then supplied to the attic 39 (shown in Figure 1) via the third flow path 41 from the second outlet 36B. As a result, in the second state, it is possible to dehumidify the attic 39 (suppress condensation in the attic 39).

[0099] In the second state, the flow of outside air A3 in the first chamber 45 (flow from the other end 45b to the one end 45a) is in the opposite direction to the flow of conditioned air A1 in the first chamber 45 in the first state shown in Figure 7(a) (i.e., it becomes a counterflow). As a result, in this embodiment, it is possible to suppress the bias in the difference in relative humidity between the first state (shown in Figure 7(a)) and the second state (shown in Figure 7(b)) from the one end 45a side to the other end 45b side of the first chamber 45 (i.e., to make the difference in relative humidity closer to uniform). Therefore, the humidity control device 15 of this embodiment makes it possible to utilize the moisture absorption and release performance of the humidity control material 43 throughout the first chamber 45 from the one end 45a side to the other end 45b side.

[0100] [Function of humidity control devices (in homes)] Thus, in this embodiment, the humidity control device 15 can be alternately switched between a first state and a second state by the drive unit 28 rotating the humidity control unit 16, and therefore does not require the damper provided in the humidity control chamber of Patent Document 1. Accordingly, the humidity control device 15 of this embodiment has a reduced number of dampers and improved maintainability.

[0101] Furthermore, in the humidity control device 15 of this embodiment, the casing 26 is arranged such that the first partition 30 and the second partition 34 are separated by a gap 44. As a result, contact between the first partition 30 and the second partition 34 is suppressed by the rotation of the humidity control unit 16. This enables a smooth switch between the first state and the second state. Moreover, in this embodiment, the first partition 30, the third partition 48, and the fourth partition 49 have gaps 58 between them and the first side material 33A and the second side material 33B, which enables a smooth switch between the first state and the second state. To effectively achieve these effects, it is preferable that the length L1 of the gaps 44 and 58 be set to, for example, 1.0 to 5.0 mm.

[0102] On the other hand, in the humidity control device 15 of this embodiment, the air transport unit 14 (first fan 14A and second fan 40) passes air through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are at positive or negative pressure (positive pressure in this example). As a result, the pressure difference inside the first chamber 45 and the second chamber 46 is smaller compared to, for example, when the first chamber 45 is set to positive pressure and the second chamber 46 is set to negative pressure, or when the first chamber 45 is set to negative pressure and the second chamber 46 is set to positive pressure. This suppresses the flow of air in the first space 29A (conditioned air A1 in this example) into the second space 29B through the gaps 44 and 58, and prevents the recovery of the humidification capacity in the second chamber 46 from being hindered. Furthermore, the air in the second space 29B (in this example, outside air A3) is prevented from flowing into the first space 29A through gaps 44 and 58, thereby preventing a decrease in the amount of moisture released into the conditioned air A1 in the first chamber 45 and a decrease in the temperature of the conditioned air A1. Therefore, the humidity control device 15 of this embodiment can improve humidity control efficiency.

[0103] Thus, the humidity control device 15 (house 2) of this embodiment can improve both maintainability and humidity control efficiency.

[0104] Preferably, the maximum airflow of the first fan 14A is set to be greater than the maximum airflow of the second fan 40. This increases the pressure in the first space 29A compared to the second space 29B, suppressing the inflow of air from the second space 29B (outside air A3 in this example) into the first space 29A through gaps 44 and 58. Therefore, a decrease in the amount of moisture released into the conditioned air A1 in the first space 29A and a decrease in the temperature of the conditioned air A1 are prevented, making it possible to improve the air conditioning and humidity control efficiency of the living room 5.

[0105] On the other hand, if the maximum airflow of the second fan 40 is relatively small, the pressure in the second space 29B will decrease. As a result, it may not be possible to adequately supply air (outside air A3) to the humidity control material 43 in the second chamber 46, which may reduce the humidity control efficiency. For this reason, it is preferable that the opening area of ​​the second outlet 36B is smaller than the opening area of ​​the first outlet 36A. This increases the pressure in the second space 29B, making it possible to efficiently supply air (outside air A3) to the humidity control material 43 in the second chamber 46. Thus, the decrease in humidity control efficiency is suppressed. The opening area of ​​the second outlet 36B can be appropriately set, for example, according to the ratio of the maximum airflow of the second fan 40 to the maximum airflow of the first fan 14A. In this embodiment, the opening area of ​​the second outlet 36B can be set, for example, to 40% to 70% of the opening area of ​​the first outlet 36A.

[0106] The air conveying section 14 preferably passes air through such a condition that the pressure in the first space 29A is greater than the pressure in the second space 29B. In this specification, the pressure in the first space 29A is defined as the value obtained by dividing the maximum airflow of the first fan 14A by the opening area of ​​the first outlet 36A. On the other hand, the pressure in the second space 29B is defined as the value obtained by dividing the maximum airflow of the second fan 40 by the opening area of ​​the second outlet 36B.

[0107] In this way, by setting the pressure in the first space 29A to be greater than the pressure in the second space 29B, the air in the second space 29B (in this example, outside air A3) is prevented from flowing into the first space 29A. This prevents a decrease in the amount of moisture released into the conditioned air A1 in the first chamber 45 and a decrease in the temperature of the conditioned air A1, thereby suppressing a decrease in the air conditioning and humidity control efficiency of the living room 5. To effectively exert this effect, the pressure in the first space 29A is preferably 1.05 to 1.20 times the pressure in the second space 29B.

[0108] [Humidity control device (second embodiment)] Figure 9 is a partial cross-sectional view of a humidity control device according to another embodiment of the present invention. In this embodiment, an airtight material 47 is provided in the gap 44 between the first partition 30 and the second partition 34. Such an airtight material 47 can more effectively suppress the inflow of air through the gap 44 between the first space 29A and the second space 29B. In order to effectively exert this effect, it is preferable that an airtight material 47 is also provided in the gap 58 between the x-axis ends of the first partition 30, the third partition 48 and the fourth partition 49 and the first side material 33A and the second side material 33B.

[0109] The airtight seal 47 is not particularly limited as long as it can prevent air from entering through the gaps 44 and 58. In this embodiment, a fibrous material such as mohair is used for the airtight seal 47. Such a fibrous material can be flexibly deformed while preventing air from entering, thus suppressing obstruction of the rotation of the humidity control unit 16. However, the airtight seal 47 is not limited to such a fibrous material; for example, it may be a resin packing material or the like.

[0110] [Humidity control device (third embodiment)] In previous embodiments, an example has been given in which air is passed through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are under positive pressure, but the embodiment is not limited to this example. For example, air may be passed through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are under negative pressure.

[0111] In this embodiment, the first fan 14A is positioned downstream of the humidity control unit 16 (in this example, the first flow path 11) and is located between the outlet 23 (first outlet 36A) and the living room 5. On the other hand, the second fan 40 is positioned downstream of the humidity control unit 16 (in this example, the third flow path 41) and is located between the second outlet 36B and the attic 39. This allows air to pass through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are under negative pressure.

[0112] Thus, in the humidity control device 15 of this embodiment, the air transport unit 14 (first fan 14A and second fan 40) passes air through the first space 29A and the second space 29B so that both the first chamber 45 and the second chamber 46 are under negative pressure. As a result, the pressure difference inside the first chamber 45 and the second chamber 46 can be reduced. Therefore, in this embodiment, the inflow of air through the gaps 44 and 58 is suppressed, and the humidity control efficiency can be improved.

[0113] Although particularly preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the illustrated embodiments and can be implemented in various modified forms.
