Description

  The present invention relates to a humidity control element including a humidity control unit capable of performing an adsorption process for adsorbing moisture in air and a desorption process for desorbing moisture to air, and an air conditioning system including the humidity control element.

  In the humidity control element described in Patent Document 1, a humidity control section (humidity control side passage 85) is formed on one surface side of a flat plate member (flat plate member 83), and a cooling section (cooling) is provided on the other surface side of the flat plate member. By forming the side passage 86), the humidity control section and the cooling section between the plurality of flat plate members are alternately stacked. Here, the humidity control unit is configured to adsorb moisture by passage of air while desorbing moisture by passage of regeneration air, and the cooling unit absorbs heat of adsorption at the time of adsorption in the humidity control unit. The cooling air is configured to pass through.

  Moreover, in the humidity control element described in Patent Document 1, a plurality of linear passages are formed in parallel in the humidity control section, and air flows in one direction along the paths in the humidity control section. Similarly, a plurality of linear passages are formed in parallel in the cooling portion, and air flows in one direction along the passage in the cooling portion. Furthermore, the direction in which air flows in the humidity control section and the direction in which air flows in the cooling section are in a state of being orthogonal. Then, the humidity control unit is cooled by the air flowing through the cooling unit in a state where the direction of air flow in the humidity control unit and the direction of air flow in the cooling unit are orthogonal to each other.

JP 2003-148768 A

  The heat of adsorption at the time of moisture adsorption in the humidity control section will cause a temperature rise in the humidity control section at the location where the adsorption has been performed, or more than the location where adsorption has been performed by the air flowing through the humidity control section. It is thought that it will be carried downstream. Therefore, it is preferable that the cooling unit cools the downstream side of the portion where the adsorption is performed in the humidity control unit or the location where the adsorption is performed in the humidity control unit.

  However, in the orthogonal humidity control element as described in Patent Document 1, the air flowing through the cooling unit may not be effectively used for cooling the humidity control unit. For example, in each of a plurality of air paths in the humidity control section, moisture adsorption processing is performed while air is flowing, and adsorption heat is generated. It may move from the side to the downstream side. That is, after the hygroscopic agent on the upstream side in the air path has already adsorbed a large amount of moisture, a large amount of adsorption may be performed on the downstream side in the path to generate heat of adsorption.

  Therefore, like an orthogonal humidity control device as described in Patent Document 1, the positional relationship is such that one air path in the cooling section intersects upstream of one air path in the humidity control section. If it exists, the air which flows through one path | route in a cooling part will cool the upstream humidity control part before much adsorption heat generate | occur | produces. In other words, the air flowing through one path in the cooling unit is only used to cool the upstream humidity control unit that does not generate much adsorption heat, and the downstream humidity control unit that must be cooled. It is not used to cool the part.

  Further, in the orthogonal humidity control element as described in Patent Document 1, the amount of air that contributes to cooling of the humidity control unit can be increased by increasing the flow rate per unit time of the air flowing through the cooling unit. it can. However, in order to increase the flow rate of air flowing to the cooling unit, it is necessary to increase the output of a fan or the like for flowing air to the cooling unit, and much energy is required accordingly.

  The present invention has been made in view of the above problems, and its purpose is to improve the adsorption performance in the humidity control section by cooling the humidity control section while suppressing an increase in energy required for operation. It is in providing a humidity control element that can be used and an air conditioning system including the humidity control element.

The characteristic configuration of the humidity control element according to the present invention for achieving the above object is that a humidity control section is formed on one surface side of the flat plate member and a cooling section is formed on the other surface side of the flat plate member. The humidity control unit and the cooling unit are alternately stacked between the plurality of flat plate members,
The humidity control unit includes a first guide member capable of guiding an air flow direction, an adsorption process for adsorbing moisture of the first air flowing while being guided by the first guide member with a moisture absorbent, and the first guide. A desorption process for desorbing moisture from the hygroscopic agent to the first air flowing while being guided by the member can be performed,
The cooling unit includes a second guide member that can guide a flow direction of air, and is generated when the humidity control unit performs the adsorption process by the second air that flows while being guided by the second guide member. A humidity control element capable of absorbing heat of adsorption through the flat plate member,
The first guide member and the second guide member are arranged so that the flow of the first air in the humidity control section and the flow of the second air in the cooling section are parallel flow or counterflow. There is a point.

According to the above characteristic configuration, the first guide member capable of guiding the direction of air flow in the humidity control unit and the second guide member capable of guiding the direction of air flow in the cooling unit are the first in the humidity control unit. The flow of air and the flow of the second air in the cooling section are arranged so as to be parallel flow or counterflow with the flat plate member interposed therebetween. That is, for example, whether a large amount of adsorption is performed by the upstream moisture absorbent in the air path of the humidity control unit and heat of adsorption is generated, or a large amount of adsorption is performed downstream in the path. Regardless of whether heat of adsorption is generated, if the second air flowing through the cooling section and the first air flowing through the humidity control section are flowing in parallel or facing each other with the flat plate member in between, The second air flowing through the cooling unit is effectively used to cool the humidity control unit. As a result, it is possible to satisfactorily perform the adsorption process in the humidity control unit. In particular, if the second air flowing through the cooling section and the first air flowing through the humidity control section are counterflows, heat exchange between the first air flowing through the humidity control section and the second air flowing through the cooling section. Increases efficiency.
Moreover, since the 2nd air which flows through the inside of a cooling part is utilized effectively in order to cool a humidity control part, in order to increase the air quantity which contributes to cooling of a humidity control part, the unit of the 2nd air which flows through a cooling part A method of increasing the flow rate per hour becomes unnecessary.
Therefore, it is possible to provide a humidity control element capable of cooling the humidity control section while suppressing an increase in energy required for operation and improving the adsorption performance in the humidity control section.

  Still another characteristic configuration of the humidity control element according to the present invention is that the first guide member is formed long in a direction in which the first air flows, and a cross section viewed from the direction in which the first air flows has a waveform. It is in the point which has the 1st corrugated member formed.

  According to the above characteristic configuration, the first air can flow along the valley portion of the first corrugated plate member.

  Still another characteristic configuration of the humidity control element according to the present invention is that one surface of the flat plate member and both surfaces of the first corrugated plate member constituting the humidity control section hold the moisture absorbent. .

  According to the above characteristic configuration, it is possible to hold a large amount of the hygroscopic agent on both the flat plate member and the first corrugated plate member having a large surface area. As a result, moisture adsorption performance by the humidity control unit can be increased.

  Still another characteristic configuration of the humidity control element according to the present invention is that the humidity control unit holds the moisture absorbent on one surface of the flat plate member and both surfaces of the first corrugated plate member, and then the flat plate. It is in the point formed by assembling the member and the first corrugated plate member.

After assembling the flat plate member and the first corrugated member, since the gap between the flat plate member and the first corrugated member is narrowed, one surface of the flat plate member and both surfaces of the first corrugated member are accessed. It becomes difficult to do. As a result, it becomes difficult to uniformly hold the hygroscopic agent on one surface of the flat plate member and both surfaces of the first corrugated plate member.
However, in this characteristic configuration, before assembling the flat plate member and the first corrugated member, that is, when one surface of the flat plate member and both surfaces of the first corrugated member can be easily accessed, one surface of the flat plate member. And a hygroscopic agent can be easily hold | maintained on both surfaces of a 1st corrugated plate member.

  Still another characteristic configuration of the humidity control element according to the present invention is that the second guide member is formed long in a direction in which the second air flows and a cross section viewed from the direction in which the second air flows has a waveform. It is in the point which has the 2nd corrugated board member formed.

  According to the above characteristic configuration, the second air can flow along the valley portion of the second corrugated plate member.

  Still another characteristic configuration of the humidity control element according to the present invention is that the flat plate member is formed using a resin material.

  According to the above characteristic configuration, the flat plate member can be easily manufactured in a desired shape using the resin material.

  The characteristic configuration of the air conditioning system according to the present invention includes the humidity control element, and flows the outdoor air taken in from an outdoor space as the first air to the humidity control section and passes through the humidity control section. 1 It is in the point which sends out air to indoor space.

  According to the above characteristic configuration, the air after the moisture is reduced from the outdoor air can be sent to the indoor space.

  Another characteristic configuration of the air conditioning system according to the present invention is that outdoor air taken in from an outdoor space is caused to flow to the cooling unit as the second air.

  According to the above characteristic configuration, air at a temperature obtained by adding heat of adsorption to the outdoor air flows through the humidity control section of the humidity control element, and air at a temperature equivalent to the outdoor air flows through the cooling section of the humidity control element. . That is, since the temperature of the air flowing through the cooling unit is lower than the temperature of the air flowing through the humidity control unit, the humidity control unit can be reliably cooled by the air flowing through the cooling unit.

It is a figure which shows the structure of an air conditioning system provided with a humidity control element. It is sectional drawing of the humidity control element of another embodiment. It is sectional drawing of the humidity control element of another embodiment.

A humidity control element E according to an embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of the humidity control element E. FIG. FIG. 2 is an exploded view of the humidity control element E. FIG. FIG. 3 is a cross-sectional view of the humidity control element E. As shown in the drawing, the humidity control element E has a plurality of flat plates in which the humidity control portion W is formed on one surface side of the flat plate member 1 and the cooling portion C is formed on the other surface side of the flat plate member 1. In the structure in which the humidity control part W and the cooling part C are alternately stacked between the members 1, that is, the structure in which the humidity control part W and the cooling part C are alternately arranged with the flat plate members 1 interposed therebetween. It has become.

  The humidity control unit W plays a role of adsorbing and desorbing moisture. Specifically, the humidity control unit W includes a first guide member 3 capable of guiding the air flow direction, and adsorbs moisture of the first air flowing while being guided by the first guide member 3 by the moisture absorbent 6. The adsorption process and the desorption process of desorbing moisture from the moisture absorbent 6 to the first air flowing while being guided by the first guide member 3 can be performed.

  The humidity control portion W is a space surrounded by the upper and lower two flat plate members 1 and the side wall plate 2. The space serving as the humidity control section W has two opening portions, an inlet Win through which air flows in and an outlet Wout through which air flows out. The air that has flowed into the humidity control unit W from the inflow port Win passes through the inside of the humidity control unit W and is discharged from the outflow port Wout. In the middle of the path through which the air inside the humidity control section W passes, a first guiding portion 9 is formed through which the air flow is guided by the first guiding member 3. For example, a plurality of gaps among the flat plate member 1, the side wall plate 2, and the first guide member 3 serve as air paths. There is an inflow region 8 on the inflow side Win side with respect to the first guide portion 9, and air is distributed to each gap in the inflow region 8. There is an outflow region 10 on the outflow port Wout side of the first guide portion 9, and the air that has passed through the gaps merges in the outflow region 10. Each gap formed between the flat plate member 1, the side wall plate 2, and the first guide member 3 (that is, the space of the first guide portion 9 through which air passes) is between the inflow region 8 and the outflow region 10. It is straight.

In this embodiment, the 1st guide member 3 has the 1st corrugated member 5a in which the cross section seen from the direction through which the 1st air flows is formed in a waveform in elongate toward the direction through which the 1st air flows. Thereby, 1st air can be flowed along the valley part of the 1st corrugated board member 5a.
In addition, one surface of the flat plate member 1 constituting the humidity control section W and both surfaces of the first corrugated plate member 5 a hold the moisture absorbent 6. That is, the hygroscopic agent 6 is provided in all the portions where the first air that has flowed into the humidity control section W comes into contact. As described above, since a large amount of the hygroscopic agent 6 can be held in both the flat plate member 1 and the first corrugated plate member 5a having a large surface area, the moisture adsorption performance by the humidity control section W can be enhanced.

  The top portion of the corrugated peak and the bottom portion of the corrugated trough that form the first corrugated plate member 5a are provided on each of the upper and lower flat plate members 1 (or the moisture absorbent 6 provided on the surface). They are touching or adhered to. In other words, the first corrugated member 5a functions as a spacer for keeping the distance between the two upper and lower flat plate members 1 constant, and the deformation of the humidity control portion W can be prevented by the first corrugated member 5a. Further, heat can be transferred inside the humidity control section W via the first corrugated plate member 5a. Furthermore, since the surface area of the 1st corrugated member 5a becomes large by making it a waveform, the quantity of the moisture absorbent 6 which the surface of the 1st corrugated member 5a can hold | maintain can be increased.

  The cooling unit C has a function of cooling the humidity control unit W. Specifically, the cooling unit C includes the second guide member 4 capable of guiding the air flow direction, and the humidity control unit W performs the adsorption process by the second air flowing while being guided by the second guide member 4. The heat of adsorption generated when this is performed can be absorbed through the flat plate member 1.

  The cooling part C is a space surrounded by two upper and lower flat plate members 1 and side wall plates 2. The space serving as the cooling unit C has two opening portions, an inlet Cin through which air flows in and an outlet Cout through which air flows out. The air that has flowed into the cooling unit C from the inflow port Cin passes through the inside of the cooling unit C and is discharged from the outflow port Cout. In the middle of the path through which the air inside the cooling section C passes, a second guiding portion 12 is formed in which the air flow is guided by the second guiding member 4. For example, a plurality of gaps among the flat plate member 1, the side wall plate 2, and the second guide member 4 serve as air paths. There is an inflow region 11 on the inlet Cin side of the second guide portion 12, and air is distributed to the gaps in the inflow region 11. There is an outflow region 13 on the outlet Cout side of the second guide portion 12, and the air that has passed through the gaps merges in the outflow region 13. Each gap formed between the flat plate member 1, the side wall plate 2, and the second guide member 4 (that is, the space of the second guide portion 12 through which air passes) is between the inflow region 11 and the outflow region 13. It is straight.

  In the present embodiment, the second guide member 4 has a second corrugated plate member 5b that is formed long in the direction in which the second air flows and has a cross section viewed from the direction in which the second air flows. Thereby, 2nd air can be flowed along the trough part of the 2nd corrugated board member 5b.

  The apex portion of the corrugated mountain and the bottom portion of the corrugated valley forming the second corrugated plate member 5b are in contact with or bonded to the upper and lower two flat plate members 1, respectively. That is, the second corrugated member 5b functions as a spacer for maintaining a constant distance between the upper and lower two flat plate members 1, and the second corrugated member 5b can prevent the cooling portion C from being deformed. Moreover, heat can be transmitted inside the cooling part C through the second corrugated plate member 5b.

  Various kinds of hygroscopic agents 6 can be used. For example, a material mainly composed of a polyacrylic acid-based resin (such as sodium polyacrylate having a crosslinked structure) can be used. Further, the binder of the flat plate member 1 and the hygroscopic agent 6 is close in polarity to the material constituting the hygroscopic agent 6 and can withstand the volume change and heat cycle of the hygroscopic agent 6 (that is, the function as the binder can be maintained). ) A flexible material can be used. For example, when a polyacrylic acid-based material as described above is used as the hygroscopic agent 6, a material such as an aqueous urethane resin, polyvinyl acetate, or ethylene-vinyl acetate copolymer can be used as the binder. Or what mixed the material mentioned above can also be utilized as a binder. In this embodiment, sodium polyacrylate is used as the hygroscopic agent 6 and an aqueous urethane resin is used as the binder.

The flat plate member 1, the corrugated plate member 5, and the side wall plate 2 can be manufactured using materials such as resin, paper, metal (for example, aluminum), glass, and ceramic.
When the hygroscopic agent 6 is held on the flat plate member 1 and the corrugated plate member 5 (first corrugated plate member 5a) by using a binder, the flat plate member 1 is used in order to improve the adhesion of these three members. The corrugated plate member 5 (first corrugated plate member 5a) is preferably a resin material having a polarity close to that of the binder or the hygroscopic agent 6 and having heat resistance. For example, as a constituent material of the flat plate member 1 and the corrugated plate member 5 (first corrugated plate member 5a), polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate, polyvinyl chloride, polyvinyl acetate Polystyrene, a copolymer of the above-described materials, or a mixture thereof can be used. Moreover, when a resin material is used for the flat plate member 1, the corrugated plate member 5, and the side wall plate 2, it can be easily manufactured into a target shape. In this embodiment, polyethylene terephthalate is used as the flat plate member 1, the corrugated plate member 5, and the side wall plate 2.

  As shown in FIGS. 1 to 3, the humidity control element E of the present embodiment has a structure in which a total of three layers of cooling units C and a total of two layers of humidity control units W are alternately stacked. That is, each humidity control part W has a structure in which the upper and lower sides are sandwiched between the cooling parts C. As a result, the heat of adsorption generated when the humidity control unit W performs the adsorption process is transmitted to and absorbed by the cooling unit C disposed on the upper and lower sides via the flat plate member 1.

Further, in the stacking direction view of the humidity control unit W and the cooling unit C, the flow of the first air in the humidity control unit W and the flow of the second air in the cooling unit C with one flat plate member 1 interposed therebetween. The first guide member 3 and the second guide member 4 are arranged so that and become parallel flow or counterflow. In particular, in the present embodiment, the inlet Win and the outlet Wout of the humidity control unit W are set so that the first air that flows to the humidity control unit W and the second air that flows to the cooling unit C are counterflows. And the inflow port Cin and the outflow port Cout of the cooling part C are set.
The inlet Win and the outlet Wout of the humidity control unit W are set so that the first air flowing through the humidity control unit W and the second air flowing through the cooling unit C are in parallel flow, and the cooling unit C The inlet Cin and the outlet Cout may be set.
Here, the flow direction of the first air in the humidity control unit W and the flow direction of the second air in the cooling unit C are completely parallel (parallel flow) as viewed in the stacking direction of the humidity control unit W and the cooling unit C. , It is not necessary to have an opposite flow), and they may intersect at a certain angle. For example, the flow direction of the first air in the humidity control section W and the flow direction of the second air in the cooling section C are about 10 degrees from each other in the stacking direction view of the humidity control section W and the cooling section C. You may cross at an angle.

  Thus, if the 1st guide member 3 and the 2nd guide member 4 are arrange | positioned as mentioned above, many adsorption | suction will be carried out with the upstream moisture absorbent 6 in the path | route of the air of the humidity control part W, for example. The second air flowing through the cooling section C is controlled regardless of whether the adsorption heat is generated and whether the adsorption heat is generated on the downstream side in the path. Effectively used to cool the wet portion W. As a result, it is possible to satisfactorily perform the adsorption process in the humidity control unit W. In particular, if the second air flowing through the cooling unit C and the first air flowing through the humidity control unit W are counterflows, the first air flowing through the humidity control unit W and the second air flowing through the cooling unit C The heat exchange efficiency between them increases. Further, since the air flowing through the cooling unit C is effectively used to cool the humidity control unit W, the unit of the air flowing through the cooling unit C in order to increase the amount of air that contributes to the cooling of the humidity control unit W A method of increasing the flow rate per hour becomes unnecessary. Therefore, it is possible to provide the humidity control element E that can cool the humidity control section W while suppressing an increase in energy required for operation, and can improve the adsorption performance in the humidity control section W.

Next, the manufacturing method of the humidity control element E of this embodiment is demonstrated. 4 and 5 are diagrams for explaining a manufacturing process of the humidity control element E. FIG.
First, as shown in FIG. 4, two kinds of materials, a corrugated plate member 5 that is formed long in the direction of air flow and has a corrugated cross section viewed from the direction of air flow, and a flat plate member 1. Is prepared (material preparation process).
Next, the moisture absorbent 6 is held on one surface of the flat plate member 1 using the binder. In addition, the 1st corrugated board member 5a is formed by hold | maintaining the same hygroscopic agent 6 also on both surfaces of the corrugated board member 5 (hygroscopic agent holding | maintenance process). On the other hand, the corrugated member 5 that does not hold the hygroscopic agent 6 can be used as the second corrugated member 5b.

If the corrugated member 5 is used as the first corrugated member 5a, the corrugated member 5 is made of a resin material as described above in consideration of the adhesiveness between the first corrugated member 5a, the binder, and the hygroscopic agent 6. It is preferable to use the first corrugated plate member 5a. The second corrugated plate member 5b may also be manufactured using the same material.
However, since it is not necessary to hold the hygroscopic agent 6 in the second corrugated plate member 5b, it is not necessary to consider the adhesiveness between the first corrugated plate member 5a, the binder, and the hygroscopic agent 6. That is, the second corrugated plate member 5b can be manufactured using a material such as resin, paper, metal (for example, aluminum), glass, or ceramic.

In this way, as shown in FIG. 5, the flat plate member 1 holding the hygroscopic agent 6 on one surface and the corrugated plate member 5 (first corrugated plate) holding the hygroscopic agent 6 on both surfaces. Three types of members can be prepared: a member 5a) and a corrugated member 5 (second corrugated member 5b) that does not hold the moisture absorbent 6 on its surface. And the humidity control element E of the structure shown in FIG. 3 can be obtained by assembling these (an assembling process).
That is, the humidity control portion W is formed by assembling the flat plate member 1 and the first corrugated member 5a after holding the moisture absorbent 6 on one surface of the flat plate member 1 and both surfaces of the first corrugated plate member 5a. The

  Thus, in the manufacturing method of the humidity control element E of the present embodiment, before assembling the flat plate member 1 and the first corrugated plate member 5a, that is, on one surface of the flat plate member 1 and both surfaces of the first corrugated plate member 5a. On the other hand, when it is easily accessible, the moisture absorbent 6 can be easily held on one surface of the flat plate member 1 and both surfaces of the first corrugated plate member 5a. In addition, since the clearance gap between the flat plate member 1 and the 1st corrugated member 5a is narrow after the flat plate member 1 and the 1st corrugated member 5a are assembled | attached, one surface of the flat plate member 1 and the 1st It becomes difficult to access both surfaces of the corrugated plate member 5a. As a result, it becomes difficult to uniformly hold the hygroscopic agent 6 on one surface of the flat plate member 1 and both surfaces of the first corrugated plate member 5a.

Next, an air conditioning system provided with the humidity control element E (E1, E2) of this embodiment is demonstrated.
FIG. 6 is a diagram illustrating a configuration of an air conditioning system including the humidity control element E. As shown in the figure, this air conditioning system includes two humidity control elements E1 and E2. As will be described later, FIG. 6 shows a state where the dehumidifying operation is performed by the humidity control element E1 and the regeneration operation is performed by the humidity control element E2. The air conditioning system flows outdoor air taken in from the outdoor space as first air to the humidity control portion W of one humidity control element E1, and sends the first air after passing through the humidity control portion W to the indoor space. It is configured as follows. The air conditioning system has an air supply passage L1 for supplying outdoor air taken in from the outdoor space into the room, and an exhaust passage L2 for discharging indoor air taken out from the indoor space to the outdoor. In the present embodiment, description of a fan, a blower and the like for flowing air is omitted.

  In the middle of the air supply passage L1, the humidity control element E1 and the sensible heat exchanger 20 are sequentially arranged from the outside toward the inside. In the middle of the exhaust passage L2, a sensible heat exchanger 20, a heater 21, and a humidity control element E2 are sequentially arranged from the room toward the outside. The air taken into the air supply passage L1 from the outdoor space is introduced into the inlet Win of the humidity control section W of the humidity control element E1, and after the adsorption processing is performed in the humidity control section W, that is, the air is dehumidified. After being performed, it exits from the outlet Wout of the humidity control section W and travels toward the sensible heat exchanger 20 via the air supply passage L1.

  In the sensible heat exchanger 20, heat is exchanged between the outdoor air after the dehumidification (moisture adsorption process) is performed by the humidity control element E1 and the indoor air taken in from the room, and the temperatures of the two approaches. It will be. That is, the outdoor air after the moisture is reduced by the moisture adsorption process in the humidity control element E1 is passed through the supply passage L1 in a state where the temperature is brought close to the temperature of the indoor air by the sensible heat exchanger 20. Through the room.

  The room air after heat exchange is performed in the sensible heat exchanger 20 is heated by a heater 21 provided in the middle of the exhaust passage L2. In the example shown in FIG. 6, a heating medium passage 22 is connected to the heater 21, and heat exchange between the heating medium flowing through the heating medium passage 22 and the indoor air flowing through the exhaust passage L <b> 2 is performed. Done. And the indoor air after temperature rising is supplied to the humidity control element E2 via the exhaust passage L2.

  The air heated by the heater 21 is introduced into the inlet Win of the humidity control section W of the humidity control element E2 through the exhaust passage L2, and after the desorption process is performed in the humidity control section W, that is, After being used for the regeneration of the moisture absorbent 6, the moisture absorbent 6 exits from the outlet Wout of the humidity control section W and is discharged outside through the exhaust passage L <b> 2.

  In addition, the air conditioning system of the present embodiment is configured such that outdoor air flows through the cooling unit C of the humidity control element E1. Specifically, the air conditioning system includes a branch part 23 in the middle of the air supply passage L1 upstream of the humidity control element E1, and a joining part 24 in the middle of the exhaust passage L2 downstream of the humidity control element E2. Has a branch passage L3. The outdoor air flowing through the branch passage L3 is introduced into the inlet Cin of the cooling unit C of the humidity control element E1, and absorbs heat of adsorption generated when the humidity control unit W performs the adsorption process through the flat plate member 1. After that, it exits from the outlet Cout of the cooling part C and reaches the confluence portion 24 of the exhaust passage L2. As described above, air having a temperature obtained by adding heat of adsorption to the outdoor air flows through the humidity control section W of the humidity control element E1, and air having a temperature equivalent to the outdoor air flows through the cooling section C of the humidity control element E1. Flowing. That is, since the temperature of the air flowing through the cooling unit C is lower than the temperature of the air flowing through the humidity control unit W, the humidity control unit W can be reliably cooled by the air flowing through the cooling unit C.

  Moreover, although illustration is abbreviate | omitted, the air conditioning system is provided with the switching mechanism etc. which switch the humidity control element E1 and the humidity control element E2. As a result, it is possible to regenerate the humidity control element E1 after being used for the adsorption process, and to use the humidity control element E2 after the regeneration of the hygroscopic agent 6 for the adsorption process. . Although not shown in the figure, an operation that humidifies the air supplied to the room using an air conditioning system is also possible.

In the said embodiment, although the structure of the humidity control element E and the structure of the air conditioning system were given and demonstrated, the structure of the humidity control element E and the structure of the air conditioning system are not limited to what was mentioned above, It changes suitably. Is possible.

For example, the shape of the 1st induction member 3 and the 2nd induction member 4 which the humidity control element E has is not limited to the waveform mentioned above. FIG. 7 is a cross-sectional view of a humidity control element E according to another embodiment. As shown in the drawing, a rib 14 is provided between the two flat plate members 1 instead of the corrugated plate member 5 described above, and the first guiding member 3 and the second guiding member 4 are formed using the rib 14. It is formed. Like the corrugated plate member 5, the rib 14 is formed long in the direction in which air flows. The rib 14 is disposed perpendicular to each of the two flat plate members 1 and can serve as a spacer between the two flat plate members 1 in addition to the role of guiding the air flow direction. In the drawing, the rib 14 provided in the humidity control portion W is referred to as a first rib 14a, and the rib 14 provided in the cooling portion C is referred to as a second rib 14b.

In the above embodiment, the material of the second guide member 4 may be changed. FIG. 8 is a cross-sectional view of a humidity control element E according to another embodiment. As shown in the drawing, a metal film 7 is formed on one surface of the flat plate member 1 constituting the cooling section C. That is, the metal film 7 is formed on one surface of the flat plate member 1, and the moisture absorbent 6 is held on the other surface of the flat plate member 1. For example, the metal film 7 can be formed using a metal such as aluminum by vapor deposition or the like. The surface on which the metal film 7 is formed becomes a passage through which the second air flows in the cooling section C, and the surface on which the moisture absorbent 6 is held is a passage through which the first air flows in the humidity control section W. Become. By forming the metal film 7 having good thermal conductivity on one surface of the flat plate member 1, heat transfer in the surface direction is promoted in the flat plate member 1. Therefore, the heat of adsorption generated when the humidity control unit W performs the adsorption process can be absorbed by the entire surface of the flat plate member 1 of the cooling unit C.

  In addition, in the above-described embodiment, the example in which the heater 21 raises the temperature of the indoor air using the heat of the heat medium flowing through the heat medium passage 22 has been described, but the configuration of the heater 21 is changed. Also good. For example, a configuration in which the heater 21 includes an electric heater and the temperature of the room air is raised using heat released from the electric heater may be employed.

  The configuration disclosed in the above embodiment (including another embodiment, the same shall apply hereinafter) can be applied in combination with the configuration disclosed in the other embodiment, as long as no contradiction occurs. The embodiment disclosed in this specification is an exemplification, and the embodiment of the present invention is not limited to this. The embodiment can be appropriately modified without departing from the object of the present invention.
