Description

Technical Field

[0001] This disclosure relates to an air conditioning rotating body and an air handling device. Background Technology

[0002] An air handling device described below is used as a heat exchanger for heat exchange between exhaust gas and supply gas. In this air handling device, a rotor made of a material with good heat storage properties, such as aluminum or stainless steel, rotates around its axis. A portion of the rotor is arranged in the exhaust passage, and the other portion of the rotor is arranged in the supply passage.

[0003] In addition, an air handling device described below is used for humidity control, deodorization, etc. The air handling device is configured such that a rotor with a honeycomb structure carrying adsorbent materials such as zeolite and porous silica rotates around its axis, and the treated air passes through a part of the rotor while the regenerated air passes through other parts of the rotor.

[0004] In air handling devices that use a rotor that functions as an air conditioner rotating body, the rotor is rotatably housed within a housing, and a sealing member that divides the air passage is provided along the diameter and outer circumference of the rotor. Patent Document 1 discloses that spokes are provided on the flat portions at both ends of the housing housing housing the rotor (honeycomb structure), and vent holes are provided between the spokes, with the width of the sealing member being larger than the width of the vent holes. In the structure of Patent Document 1, since the sealing member contacts the flat portions at both ends of the housing, the honeycomb structure does not directly contact the sealing member, thus preventing wear on the honeycomb structure.

[0007] Patent Document 1: Japanese Patent No. 3755708 Summary of the Invention

[0008] -The technical problem the invention aims to solve-

[0009] However, in the structure of Patent Document 1, because the end of the sealing component is always in contact with the two end planes of the housing, the load is concentrated, and therefore the end of the sealing component is cut and worn faster than other parts. As a result, the following problems occur at the end of the sealing component: air leakage, reduced effective ventilation, and unnecessary increase in air volume, etc.

[0010] The purpose of this disclosure is to suppress air leakage caused by wear of sealing components that divide the air passage in an air conditioning rotating body having a rotor.

[0011] - Technical solutions used to solve technical problems -

[0012] The first aspect of this disclosure is an air conditioning rotating body 30 having a rotor 10, the rotor 10 being cylindrical and rotatably housed within a housing 50, the air conditioning rotating body 30 processing air passing through the rotor 10 axially, characterized in that: a sealing member 51 is provided on the housing 50, the sealing member 51 extending radially along the rotor 10 and dividing an air passage, at least one spoke 25 being provided on the axial end face of the rotor 10 in contact with the sealing member 51, the contact point of the sealing member 51 with the spoke 25 moving radially as the rotor 10 rotates.

[0013] In the first aspect, the contact point between the spokes 25 disposed on the axial end face of the rotor 10 and the sealing member 51 that divides the air passage moves radially as the rotor 10 rotates. Therefore, it is possible to suppress localized wear caused by load concentration on a specific part of the sealing member 51, thereby preventing air leakage.

[0014] A second aspect of this disclosure is, based on the first aspect, characterized in that: the sealing member 51 contacts the plurality of spokes 25.

[0015] In the second aspect, the structure in which the sealing member 51 is supported by the spokes 25 at multiple points can further suppress local wear of the sealing member 51.

[0016] A third aspect of this disclosure is, based on the first or second aspect, characterized in that: the spokes 25 are bent circumferentially along the rotor 10.

[0017] In the third aspect, by supporting the sealing member 51 with the spokes 25 that are bent in the circumferential direction, the support point of the sealing member 51 can be moved when the rotor 10 rotates, thus suppressing local wear of the sealing member 51.

[0018] A fourth aspect of this disclosure is, based on any one of the first to third aspects, characterized in that: a reinforcing rib 26 is further provided on the end face of the rotor 10, the reinforcing rib 26 extending radially.

[0019] In the fourth aspect, since reinforcing ribs 26 are provided on the axial end face of the rotor 10, the support structure of the rotor 10 can be strengthened, and the deflection of the rotor 10 can be suppressed. Therefore, the widening of the gap between the rotor 10 and the sealing member 51 can be suppressed, thereby suppressing air leakage.

[0020] The fifth aspect of this disclosure is, based on any one of the first to fourth aspects, characterized in that: annular components 27 and 28 are further provided on the end face of the rotor 10, the annular components 27 and 28 surrounding the center of the rotor 10 circumferentially.

[0021] In the fifth aspect, due to the arrangement of the annular components 27 and 28, the number of support points for the sealing component 51 is increased, thus dispersing the load on each support point of the sealing component 51, thereby further suppressing localized wear of the sealing component 51. Furthermore, by connecting the annular components 27 and 28 to the spokes 25, the spokes 25 can be strengthened.

[0022] The sixth aspect of this disclosure is, based on any one of the first to fifth aspects, characterized in that: the spokes 25 are disposed on two end faces in the axial direction of the rotor 10, and when viewed along the axial direction, the spokes 25 disposed on the two end faces overlap.

[0023] In the sixth aspect, air flowing into the rotor 10 from the opening area on one side of the rotor 10 along the axial direction can flow out from the opening area on the other side without colliding with the non-opening area on the other side of the rotor 10 along the axial direction. Therefore, by increasing the substantial opening area on both sides of the rotor 10 along the axial direction, the air conditioning capacity can be improved.

[0024] The seventh aspect of this disclosure is an air handling apparatus, characterized in that: the air handling apparatus includes an air conditioning rotating body 30 as described in any one of the first to sixth aspects.

[0025] In the seventh aspect, since the air conditioning rotating body 30 is included, which can suppress air leakage caused by wear of the sealing component 51 that divides the air passage, the performance of the air handling unit 1 can be improved, such as dehumidification and humidification performance, heat exchange performance, etc. Attached Figure Description

[0037] (Implementation Method)

[0038] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that this disclosure is not limited to the embodiments shown below, and various modifications can be made without departing from the technical concept of this disclosure. The accompanying drawings are used to illustrate this disclosure in a summary manner; therefore, for ease of understanding, dimensions, scales, or quantities are sometimes exaggerated or simplified as needed.

[0039] <Structure of Air Handling Unit>

[0040] The air handling device 1 in this embodiment is configured as, for example, a dehumidification and humidification device, such as... Figure 1 As shown, the air handling unit 1 is provided with air passages 3 and 4, which are divided by partition wall 2. In the air handling unit 1, outdoor air OA is drawn in from the outside and supplied to the room as supply gas SA through air passage 3, and return air RA is drawn in from the room and discharged to the outside as exhaust gas EA through air passage 4.

[0041] The air conditioner rotating body 30 of this embodiment has a rotor 10 and a rotating shaft 11. The rotor 10 is cylindrical and is composed, for example, of a honeycomb adsorption element carrying zeolite, etc., and the rotating shaft 11 passes through the center of the rotor 10. The rotating shaft 11 is arranged at the boundary between the air passage 3 and the air passage 4. In other words, the air conditioner rotating body 30 is arranged to span both the air passage 3 and the air passage 4. The air passage 3 and the air passage 4 are respectively configured to allow air to pass through the rotor 10 relative to each other along the axial direction. The sealing member 51 that divides the air passage 3 and the air passage 4 is slidably abutted against the two end faces along the axial direction of the air conditioner rotating body 30.

[0042] In air passage 3, a heat exchanger 5 is arranged upstream (outdoor side) of the air conditioner rotating body 30, and a compressor 6 and a blower 7 are arranged sequentially downstream (indoor side) of the air conditioner rotating body 30. In air passage 4, a heat exchanger 8 is arranged upstream (indoor side) of the air conditioner rotating body 30, and a blower 9 is arranged downstream (outdoor side) of the air conditioner rotating body 30.

[0043] When the air handling unit 1 is in dehumidification operation, the rotor 10 rotates while the adsorbent material of the rotor 10 adsorbs water vapor from the air passing through the air passage 3, thereby generating dehumidified air. Conversely, water vapor is desorbed from the adsorbent material of the rotor 10 by air heated to a predetermined temperature and passing through the air passage 4, thereby regenerating the adsorbent material. In this case, the heat exchanger 5 in the air passage 3 operates as an evaporator, and the heat exchanger 8 in the air passage 4 operates as a condenser.

[0044] When the air handling unit 1 is in humidification operation, the rotor 10 rotates while the adsorbent material of the rotor 10 adsorbs water vapor from the air passing through the air passage 4. Conversely, air heated to a predetermined temperature and passing through the air passage 3 desorbs water vapor from the adsorbent material of the rotor 10, thereby generating humidified air and regenerating the adsorbent material. In this case, the heat exchanger 5 in the air passage 3 operates as a condenser, and the heat exchanger 8 in the air passage 4 operates as an evaporator.

[0045] <Structure of the rotating air conditioner body>

[0046] In air handling unit 1, such as Figure 2 As shown, the air conditioner rotating body 30 is rotatably housed within the housing 50. The air conditioner rotating body 30 has a protective container 20 that protects the rotor 10. The protective container 20 includes a side plate 22 that covers the outer peripheral surface of the rotor 10. The protective container 20 rotates integrally with the rotor 10 about the rotation axis 11.

[0047] The housing 50 is composed of an upper plate 50a, a lower plate 50b, and a support column 50c. The upper plate 50a and lower plate 50b are approximately square. An air conditioning rotating body 30 is sandwiched between the upper plate 50a and lower plate 50b, with the upper plate 50a and lower plate 50b facing each other along the axial direction of the rotor 10. The support column 50c connects the upper plate 50a and lower plate 50b at their respective four corners. An exhaust port 53 and an intake port 54 are provided on the upper plate 50a. The exhaust port 53 is connected to the downstream side of the air passage 3, and the intake port 54 is connected to the upstream side of the air passage 4. An intake port 52 and an exhaust port 55 are provided on the lower plate 50b. The intake port 52 is connected to the upstream side of the air passage 3, and the exhaust port 55 is connected to the downstream side of the air passage 4. When viewed along the axial direction of the rotor 10, the intake ports 52 and 54 and the exhaust ports 53 and 55 each have an approximately semi-circular shape. When viewed along the axial direction of the rotor 10, the intake port 52 of the lower plate portion 50b coincides with the exhaust port 53 of the upper plate portion 50a. When viewed along the axial direction of the rotor 10, the intake port 54 of the upper plate portion 50a coincides with the exhaust port 55 of the lower plate portion 50b.

[0048] Sealing members 51 are respectively arranged at the boundary between the exhaust port 53 and the intake port 54 of the upper plate portion 50a, and at the boundary between the intake port 52 and the exhaust port 55 of the lower plate portion 50b. The sealing members 51 are slidably abutted against each end face in the axial direction of the air conditioner rotating body 30. As a result, it is possible to prevent air drawn in from the intake port 52 of the lower plate portion 50b from passing through the rotor 10, but instead passing between the rotor 10 and the lower plate portion 50b and leaking out to the exhaust port 55 of the lower plate portion 50b. It is also possible to prevent air drawn in from the intake port 54 of the upper plate portion 50a from passing through the rotor 10, but instead passing between the rotor 10 and the upper plate portion 50a and leaking out to the exhaust port 53 of the upper plate portion 50a.

[0049] On the outer periphery of the rotor 10, specifically, on the upper and lower parts of the side plate 22 covering the outer peripheral surface of the rotor 10, rotor-side sealing portions 23 are respectively provided. On the upper plate portion 50a and the lower plate portion 50b, opposite to the rotor-side sealing portions 23, housing-side sealing portions 56 are also provided. The rotor-side sealing portions 23 and housing-side sealing portions 56 constitute a labyrinth-type sealing structure 100 that interlocks with each other. In other words, a labyrinth-type sealing structure 100 is provided between the outer periphery of the rotor 10 and the aforementioned housing 50. This prevents air drawn in from the intake port 52 of the lower plate portion 50b from bypassing the rotor 10 and leaking out to the exhaust port 53 of the upper plate portion 50a. It also prevents air drawn in from the intake port 54 of the upper plate portion 50a from bypassing the rotor 10 and leaking out to the exhaust port 55 of the lower plate portion 50b. In this way, the labyrinth seal structure 100 can suppress both air leakage from the rotor center side to the outer periphery side and air leakage from the outer periphery side to the center side. A first protrusion and a second protrusion can also be provided in the labyrinth seal structure 100, wherein the first protrusion protrudes axially toward the housing 50 along the rotor 10, and the second protrusion protrudes axially toward the rotor 10. If the labyrinth seal structure 100 is formed by the engagement of the protrusions protruding axially along the rotor, the sealing performance can be easily maintained even if, for example, the outer periphery of the rotor 10 changes axially due to shaft offset.

[0050] In this embodiment, the rotor 10 is, for example, a honeycomb adsorption element carrying zeolite, etc. Figure 3 As shown, the rotor 10 is configured as a cylinder with a through hole 15 at its center. Figures 4-6 As shown, the protective container 20 for protecting the rotor 10 has an inner cylinder 21 and a side plate 22. The inner cylinder 21 is embedded in the through hole 15 of the rotor 10 and supports the rotating shaft 11. The side plate 22 is annular and covers the outer peripheral surface of the rotor 10. The protective container 20 can be, for example, a resin molded product or made of a metal plate. The side plate 22 is configured to be separable into an upper side plate 22A and a lower side plate 22B, so that the protective container 20 can be easily installed on the rotor 10 and removed from the rotor 10. Annular rotor-side sealing portions 23 are respectively provided at the upper and lower parts of the side plate 22. An annular gear 24 is provided at the center of the outer peripheral surface of the side plate 22. The annular gear 24 is used to rotate the air conditioner rotating body 30 by means of a motor (not shown) and a small gear. The inner cylinder 21 and the side plate 22 are connected by spokes 25 and reinforcing ribs 26 that contact the axial end faces of the rotor 10. The openings on the axial end faces of the rotor 10, where the spokes 25 and reinforcing ribs 26 are not located, serve as vents for the air conditioning rotating body 30. The spokes 25 may be bent circumferentially along the rotor 10. Alternatively, the reinforcing ribs 26 may extend radially and cut into the axial end faces of the rotor 10. Figure 3In the rotor 10 shown, a groove 10a for cutting into a portion of the reinforcing rib 26 is formed radially on the end face of the rotor 10 in the axial direction.

[0051] like Figure 6 As shown, the sheet-like sealing member 51 dividing the air passages 3 and 4 slidably abuts against each end face along the axial direction of the air conditioner rotating body 30. The sealing member 51 is made of an elastomer, such as rubber, and is arranged radially along the rotor 10. To improve the durability of the sealing member 51 when it is formed of an elastomer, the front end surface (sliding surface) of the sealing member 51 may also be coated with a resin material or metal material with excellent sliding properties. Alternatively, the front end of the sealing member 51 may also be formed with a resin material or metal material with excellent sliding properties.

[0052] On the upper plate 50a and lower plate 50b, support members 57, for example made of resin, are formed to divide the air intake ports 52 and 54 and the exhaust ports 53 and 55, respectively. The sealing member 51 is held in place by sandwiching a portion of the sealing member 51 between the side of the support member 57 and the plate-like body 58. The support member 57 extends radially in two opposite directions of 180° from the inner cylinder 21 of the protective container 20. Alternatively, by tilting the sheet-like surface of the sealing member 51 relative to the axial direction of the rotor 10, a margin can be provided in the contact area between the axial end faces of the air conditioning rotating body 30 and the sealing member 51. In this way, compared to the case where the sheet-like surface of the sealing member 51 is arranged perpendicular to the axial direction of the rotor 10, the sealing structure can be easily maintained even if the rotor 10 and other components are displaced axially.

[0053] In this embodiment, since the air conditioning rotating body 30, i.e., the rotor 10, is rotated with the spokes 25 arranged on each end face along the axial direction of the rotor 10, direct contact between the rotor 10 and the sealing member 51 can be avoided by providing the spokes 25. This suppresses wear on the rotor 10. As for the material of the spokes 25, i.e., the protective container 20, by using a material with higher sliding properties than the surface material of the rotor 10, wear on the sealing member 51 can be suppressed.

[0054] like Figure 7As shown, the air conditioner rotating body 30 is rotatably housed within the housing 50. Near the air conditioner rotating body 30 on the lower plate 50b of the housing 50, a motor 60 and a small gear 62 connected to the rotating shaft 61 of the motor 60 are provided. If the small gear 62 is driven to rotate by the motor 60, the annular gear 24 of the side plate 22 covering the outer peripheral surface of the rotor 10 will be driven to rotate by the small gear 62, thereby rotating the air conditioner rotating body 30. The rotating shaft 11 of the air conditioner rotating body 30, i.e., the rotor 10, is fixedly supported in the inner cylinder 21 of the protective container 20, and the portion of the rotating shaft 11 protruding from the upper and lower ends of the inner cylinder 21 is held rotatably by bearing portions 12. On the surfaces of the upper plate 50a and lower plate 50b, opposite to the air conditioner rotating body 30, bearing supports 13 are provided along the boundaries of the intake port 52 and exhaust port 53, and the boundaries of the intake port 54 and exhaust port 55. The bearing portions 12 are mounted on the bearing supports 13. The support member 57 of the sealing member 51 is installed on the side of the bearing support 13 facing the air conditioner rotating body 30.

[0055] Annular support members 59, for example made of resin, are formed at the periphery of the exhaust port 53 and intake port 54 of the upper plate portion 50a, and at the periphery of the intake port 52 and exhaust port 55 of the lower plate portion 50b. A housing-side sealing portion 56 is installed on the side of the annular support member 59 facing the air conditioner rotating body 30. The end face of the support member 57 near the outer periphery of the rotor 10 is connected to the inner periphery of the annular support member 59.

[0056] <Contact between sealing components and air conditioner rotating body>

[0057] Figure 8 This is a top view of the air conditioner rotating body 30, viewed axially upwards from the rotor 10 with the upper plate 50a of the housing 50 removed. It should be noted that... Figure 8 The diagram of the structure (support member 57, etc.) that retains the sealing member 51 is omitted.

[0058] In this embodiment, such as Figure 8 As shown, by providing spokes 25 with a thickness of approximately 1 to 2 mm as steps on each end face of the rotor 10 along its axial direction, the sealing member 51 contacts the spokes 25, thereby preventing direct contact between the sealing member 51 and the rotor 10. This suppresses wear on the rotor 10. Furthermore, by using a material with better sliding properties than the material of the rotor 10, wear on the sealing member 51, which contacts the spokes 25, can be suppressed when the air conditioning rotating body 30 rotates.

[0059] It should be noted that if the gap between each end face of the rotor 10 in the axial direction and the sealing component 51 is too large, air leakage will occur through the gap. Therefore, the thickness of the spokes 25 is preferably about 3 mm or less, and more preferably about 1.5 mm or less.

[0060] As one of the features of this embodiment, the shape of the spokes 25 (the shape viewed from the axial direction of the rotor 10) is set such that the contact point of the sealing member 51 extending radially along the rotor 10 with the spokes 25 (at... Figure 8 (Indicated by a dashed circle) It moves radially as the rotor 10 rotates. For example, as... Figure 8 As shown, if the spokes 25 are shaped like an arc bending along the circumference of the rotor 10, then as the rotor 10 rotates, the contact point of the spokes 25 with the sealing member 51 moves from the radially inner side to the radially outer side of the rotor 10 on the arc-shaped spokes 25. Figure 8 Viewed from the axial upward side of the rotor 10, a solid arrow indicates the movement trajectory of the contact point between the spokes 25 and the sealing member 51 as the air conditioner rotating body 30 rotates counterclockwise. If focusing on the sealing member 51, the contact point that contacts the spokes 25 moves radially as the rotor 10 rotates.

[0061] It should be noted that the shape of the spokes 25 is not particularly limited as long as they have a portion that extends radially at an inclination relative to the rotor 10. In addition to being arc-shaped, they can also be S-shaped or serrated, etc.

[0062] like Figure 8 As shown, the sealing component 51 can also contact the multiple spokes 25 at any rotational position of the air conditioner rotating body 30. Figure 8 In the middle, a sealing component 51 with a radius equivalent to that of the rotor 10 contacts the three spokes 25.

[0063] Moreover, such as Figure 8 As shown, radially extending reinforcing ribs 26 can also be provided on each end face of the rotor 10 in the axial direction. At least a portion of the reinforcing rib 26 can also be cut into the end face of the rotor 10 in the axial direction, for example, about 1 cm. The reinforcing rib 26 can be connected to one or more spokes 25. In the axial direction of the rotor 10, the end face of the reinforcing rib 26 can be made approximately flush with the end face of the spoke 25, or the end face of the reinforcing rib 26 can be made lower than the end face of the spoke 25. In the latter case, contact between the reinforcing rib 26 and the sealing member 51 can be suppressed, thereby suppressing wear of the sealing member 51.

[0064] <Effects of the Implementation Method>

[0065] According to the air conditioner rotating body 30 of this embodiment, the contact point between the spokes 25 provided on the axial end face of the rotor 10 and the sealing member 51 that divides the air passage moves radially as the rotor 10 rotates. Therefore, it is possible to suppress localized wear caused by load concentration on a specific part of the sealing member 51, thereby preventing air leakage. Since the replacement frequency of the sealing member 51 caused by wear can be reduced, it is possible to suppress the increase in cost and the decrease in operating efficiency.

[0066] In the air conditioner rotating body 30 of this embodiment, the sealing member 51 may also contact multiple spokes 25. This results in a structure where the sealing member 51 is supported by the spokes 25 at multiple points. When the load on the sealing member 51 is equal to the force required for the sealing member 51, which has deformed due to contact with the spokes 25, to return to its original shape, if the sealing member 51 is supported by multiple points of the spokes 25, the load at each contact point of the sealing member 51 will be distributed. Since the amount of wear on the sealing member 51 is proportional to the load it receives, the structure where the sealing member 51 is supported by multiple points of the spokes 25 can further suppress localized wear of the sealing member 51. In contrast, in the structure of Patent Document 1, since the end of the sealing member is always in contact with the rotor housing, the load is concentrated, resulting in wear at the end of the sealing member.

[0067] In the air conditioner rotating body 30 of this embodiment, the spokes 25 may also have a shape that is bent circumferentially along the rotor 10. In this way, by supporting the sealing member 51 by the bent spokes 25, the support point of the sealing member 51 can be moved radially along the rotor 10 as the rotor 10 rotates. As a result, local wear of the sealing member 51 can be suppressed.

[0068] In the air conditioner rotating body 30 of this embodiment, a radially extending (i.e., straight) reinforcing rib 26 may be provided on the axial end face of the rotor 10. This strengthens the support structure of the rotor 10 and suppresses rotor 10 deflection. Therefore, it can suppress the widening of the gap between the rotor 10 and the sealing member 51, thereby suppressing air leakage.

[0069] The air handling apparatus 1 according to this embodiment includes an air conditioning rotating body 30 that can suppress air leakage caused by wear of the sealing member 51 that divides the air passages 3 and 4. Therefore, the performance of the air handling apparatus 1 can be improved, such as dehumidification and humidification performance, heat exchange performance, etc.

[0070] (Variation Example 1)

[0071] Hereinafter, a variation of the present disclosure will be described with reference to the accompanying drawings.

[0072] The difference between this variation 1 and the above-described embodiment is that: Figure 9 As shown, an annular component 27 is provided on the axial end face of the rotor 10, circumferentially surrounding the center of the rotor 10. Specifically, a perfectly circular component concentric with the rotor 10 is provided. It should be noted that... Figure 9 In the middle, to and Figure 8 The same components as those in the above embodiments are labeled with the same reference numerals.

[0073] In this modified example 1, in addition to the same effects as in the above-described embodiments, the following effects can also be obtained: By arranging the annular member 27, the number of support points for the sealing member 51 increases, thus distributing the load at each support point of the sealing member 51, thereby further suppressing localized wear of the sealing member 51. By connecting the annular member 27 to the spokes 25, the spokes 25 can be strengthened.

[0074] (Variation Example 2)

[0075] The following description, with reference to the accompanying drawings, will illustrate a variation of this disclosure, Example 2.

[0076] In the above variation example 1, such as Figure 9 As shown, a circular component concentric with the rotor 10 is provided as the annular component 27. In contrast, in this modified example 2, as... Figure 10 As shown, an elliptical member with a focal point at the center of the rotor 10 is provided as the annular member 28. It should be noted that... Figure 10 In the middle, to and Figure 9 The same constituent elements as those in the above-described modified example 1 are labeled with the same reference numerals. Figure 10 In the middle, it is represented by a dashed line. Figure 9 The ring-shaped component 27 shown.

[0077] In this modified example 2, in addition to the same effects as in modified example 1, the following effect can also be obtained: Compared to the structure of modified example 1, in the structure of this modified example 2, the contact point between the sealing member 51 and the annular member 28 moves radially along the rotor 10 as the rotor 10 rotates, thus suppressing localized wear of the sealing member 51. In this case, it is more preferable to have a smaller width of the annular member 28 in the radial direction of the rotor 10 compared to the moving distance of the contact point between the sealing member 51 and the annular member 28.

[0078] It should be noted that, as the annular component 28, a circular component that is eccentric to the rotor 10 is provided instead of an elliptical component with a focal point at the center of the rotor 10, and the same effect as in this modified example 2 can be obtained.

[0079] (Variation Example 3)

[0080] The following description, with reference to the accompanying drawings, will illustrate a variation of this disclosure.

[0081] In this variation example 3, as Figure 11 As shown, spokes 25 are disposed on two end faces of the rotor 10 along the axial direction, and the spokes 25 disposed on the two end faces are arranged to overlap each other when viewed along the axial direction of the rotor 10. Figure 11 In the diagram, (a) shows the planar structure of the protective container 20 including the rotating shaft 11 as viewed from one side along the axial direction of the rotor 10; (b) shows the side structure of the protective container 20 including the rotating shaft 11 as viewed radially along the rotor 10; and (c) shows the planar structure of the protective container 20 including the rotating shaft 11 as viewed from the other side along the axial direction of the rotor 10. It should be noted that in... Figure 11 In the middle, to and Figure 8 The same components as those in the above embodiments are labeled with the same reference numerals.

[0082] like Figure 11 As shown, in this modified example 3, the protective container 20 does not have reinforcing ribs 26, but instead has annular members 27 similar to those in modified example 1. Here, the annular members 27 provided on each end face along the axial direction of the rotor 10 are arranged to overlap each other when viewed along the axial direction of the rotor 10.

[0083] In this modified example 3, spokes 25 and the like are mirror-symmetrically arranged on both end faces of the rotor 10 along the axial direction. Therefore, air flowing into the rotor 10 from the opening area on one side of the rotor 10 along the axial direction can flow out from the opening area on the other side without colliding with the non-opening area on the other side of the rotor 10 along the axial direction. Thus, the substantial opening area on both sides of the rotor 10 along the axial direction is increased, thereby improving air conditioning capacity.

[0084] It should be noted that in this modified example 3, the reinforcing ribs 26 can also be arranged on each end face of the rotor 10 in the axial direction, and the reinforcing ribs 26 can be arranged to coincide when viewed along the axial direction of the rotor 10. Alternatively, the annular component 27 may not be provided on the protective container 20. Or, the same annular component 28 as in modified example 2 can be arranged on each end face of the rotor 10 in the axial direction, so that they coincide when viewed along the axial direction of the rotor 10, thereby replacing the annular component 27.

[0085] (Other implementation methods)

[0086] In the above embodiments (including variations, the same applies below), the rotor 10 of the air conditioning rotating body 30 uses a honeycomb adsorption element carrying zeolite, and the air handling device 1 is configured as a dehumidification and humidification device. However, it is also possible to use, for example, the air conditioning rotating body described below to configure a deodorization device, a gas separation device, etc., in which a honeycomb adsorption element carrying other adsorption materials such as porous silica or activated alumina is used as the rotor. Alternatively, for example, the air conditioning rotating body described below can be used to configure a heat exchanger, which has a rotor made of a material with good heat storage properties such as aluminum or stainless steel.

[0087] In the above embodiment, the air conditioning rotating body 30 is arranged in the air handling unit 1 such that the radial direction of the rotor 10 extends in the horizontal direction. However, it is also possible to arrange the air conditioning rotating body 30 in the air handling unit 1 such that the radial direction of the rotor 10 extends in the vertical direction.

[0088] In the above embodiment, two air passages, namely air passage 3 and air passage 4, are provided in the air handling unit 1, and the air conditioner rotating body 30 is arranged to span both air passages 3 and air passage 4. However, there is no particular limitation on the number of air passages provided in the air handling unit 1 (i.e., the number of air passages in which the air conditioner rotating body 30 is arranged), and there may be three or more.

[0089] The embodiments and variations have been described above, but it should be understood that various changes can be made to the methods or solutions without departing from the spirit and scope of the claims. Furthermore, the above embodiments and variations can be appropriately combined or substituted as long as the function of the object of this disclosure is not affected.
