Description

  The present invention relates to a humidity control system that adjusts indoor humidity.

  Since the radiation-type air conditioning equipment does not forcibly generate airflow, it can provide a comfortable indoor environment. Examples of such radiation-type air conditioning equipment include panel radiators as disclosed in Patent Document 1 and Patent Document 2.

  Panel radiators could only be applied to small heating equipment, but recently large panel radiators that can be used for both heating and cooling have been developed. Large panel radiators have the advantage that the entire room can be brought to a nearly uniform temperature.

JP 2005-127606 A Japanese Patent Laid-Open No. 2003-083559

  However, when the panel radiator is used for cooling, the panel radiator is condensed and the humidity around the panel radiator becomes 100%. Therefore, if the panel radiator is installed near the wall, mold is likely to occur on the wall. There was a problem. Such a problem of dew condensation is not particularly problematic in a large facility or the like, but becomes a serious problem when a panel radiator is installed in a narrow space such as a house. For this reason, when installing a large panel radiator for both air conditioning and heating in a house, it is necessary to install the panel radiator away from the wall to some extent or to separately control the humidity in the room.

  Also, the occurrence of condensation as described above is not preferable from the viewpoint of energy saving. The amount of cooling heat required to lower the indoor temperature by 1 ° C. in summer is about twice the amount of heating heat required to increase the indoor temperature by 1 ° C. in winter. This is because the latent heat of water vapor is released by condensation. Therefore, from the viewpoint of energy saving, it is desirable to separately control indoor humidity to prevent the occurrence of condensation. In winter, it is desirable to humidify the room because the room is dry, but if an inexpensive humidifier is used, it tends to be humidified too much. Therefore, appropriate humidity management is desired even in winter.

  However, when trying to manage humidity with an air conditioner or the like, a forced air flow is generated by mechanical ventilation, which greatly impairs the comfort of the indoor environment. Furthermore, since a large amount of electricity is consumed for humidity management, it is not desirable from the viewpoint of energy saving.

  As another humidity management method, for example, it is conceivable to use a desiccant (zeolite) device. This is an improvement over the industrial one using silica gel. The silica gel type uses a refrigerator when dehumidifying and a heater when humidifying, whereas the zeolite type can be dehumidified at room temperature and uses a heater when humidifying. Many of the zeolite types use a disk, so it is easy to reduce the size. On the other hand, because the behavior differs between the center of the disk and the outside of the disk, it is difficult to increase the size. In addition, in a factory or the like, excess heat can be used for a heater without using electricity, but in a place such as a house, electricity is often used for the heater, which is a problem from the viewpoint of energy saving.

  Recently, a zeolite type that can absorb and release moisture at a relatively low temperature (around 25 ° C.) without using a heater has been developed. However, since moisture absorption and dehumidification in the vicinity of such a low temperature is slow, it is necessary to increase the size of the equipment in order to absorb or desorb a large amount without using external energy such as a heater. However, the conventional disc-shaped desiccant type is not suitable for increasing the size as described above.

  Then, this invention makes it a subject to provide the humidity control system which can perform indoor humidity management with little energy, maintaining a comfortable indoor environment.

  The present invention will be described below.

  The present invention includes an indoor side moisture absorbing unit provided with a moisture absorbing material arranged indoors, an outdoor side moisture absorbing unit provided with a moisture absorbing material arranged outside the room, and a wall separating the room and the outside, The wall has openings in the upper and lower parts in the vertical direction, and the upper opening in the upper part connects the upper end in the vertical direction of the indoor moisture absorption part and the upper end in the vertical direction of the outdoor moisture absorption part. In the opening, the lower end in the vertical direction of the indoor hygroscopic part and the lower end in the vertical direction of the outdoor hygroscopic part are connected, and the hygroscopic material can absorb and release moisture at room temperature, and is provided in the indoor hygroscopic part. When the hygroscopic material absorbs moisture and the indoor hygroscopic part becomes heavier than the outdoor hygroscopic part, the indoor hygroscopic part is lowered, so that the upper end of the outdoor hygroscopic part is drawn into the room from the opening and the lower end of the indoor hygroscopic part Is pulled out of the room from the opening, When the hygroscopic material provided in the side hygroscopic part releases moisture and the indoor side hygroscopic part becomes lighter than the outdoor hygroscopic part, the outdoor hygroscopic part is lowered and the upper end of the indoor hygroscopic part is pulled out of the opening to the outside. At the same time, it is a humidity control system in which the lower end of the outdoor moisture absorption part is drawn into the room through the opening.

  In the present invention, the “indoor hygroscopic part” and the “outdoor hygroscopic part” are simply distinguished by the positions where they are arranged, and are not distinguished by the structure. That is, the indoor side portion of the portion provided with the hygroscopic material is referred to as an “indoor side hygroscopic portion”, and the outdoor portion of the portion provided with the hygroscopic material is referred to as an “outdoor hygroscopic portion”. Therefore, even if the same part is located on the indoor side, it is referred to as an “indoor hygroscopic part”, and when it is located on the outdoor side, it is referred to as an “outdoor hygroscopic part”.

  In the humidity control system of the present invention described above, the indoor moisture absorption part and the outdoor moisture absorption part include a strip-shaped connector having a predetermined width in the horizontal direction, and a plurality of moisture absorbents fixed to the connector. It is preferable.

  In the humidity control system of the present invention, the moisture absorbing material is enclosed in a bag-shaped body formed in a cylindrical shape by a moisture-permeable material, and the bag-shaped body is disposed so that the longitudinal direction is horizontal. It is preferable that a plurality are arranged in parallel in the vertical direction.

  According to the humidity control system of the present invention, since an air flow is not forcibly generated, a comfortable indoor environment can be maintained. In addition, according to the humidity control system of the present invention, it is possible to appropriately manage indoor humidity, so even if a large panel radiator combined with air conditioning is installed near the wall, occurrence of problems due to condensation can be suppressed efficiently. Humidity can be adjusted. Furthermore, according to the humidity control system of the present invention, indoor humidity management can be performed with a minimum amount of energy by effectively using a hygroscopic material capable of absorbing and releasing moisture at a relatively low temperature.

FIG. 1B is a diagram schematically showing a horizontal section of the humidity control system 10. FIG. 2A schematically shows a vertical section of the humidity control system 10 ′. FIG. 2B is a diagram schematically showing a horizontal section of the humidity control system 10 ′.

  The above-mentioned operation and gain of the present invention will be clarified from the following embodiments for carrying out the invention. Hereinafter, the present invention will be described based on embodiments shown in the drawings. However, the present invention is not limited to these embodiments. Each drawing is simplified for convenience of illustration and easy understanding. Some of the repetitive symbols are omitted.

  FIG. 1A is a diagram schematically illustrating a vertical section of the humidity control system 10, and FIG. 1B is a diagram schematically illustrating a horizontal section of the humidity control system 10.

  A part of the humidity control system 10 is disposed in a room surrounded by the ceiling 1, the floor 2 and the walls 3, 4, and 5. More specifically, the humidity control system 10 includes a room-side moisture absorption unit 11 provided with a moisture-absorbing material 13 arranged indoors, an outdoor-side moisture absorption unit 12 provided with a moisture-absorbing material 13 arranged outdoors, And a wall 3 separating the outdoor. In addition, the indoor side moisture absorption part 11 and the outdoor side moisture absorption part 12 have the same structure, and the indoor side moisture absorption part 11 and the outdoor side moisture absorption part 12 are distinguished only by the position where they are arrange | positioned. . That is, the indoor side portion of the portion provided with the hygroscopic material 13 is referred to as the indoor side hygroscopic portion 11, and the outdoor portion of the portion provided with the hygroscopic material 13 is referred to as the outdoor hygroscopic portion 12. Therefore, even if it is the same site | part, when located in the room inner side, it will be called the indoor side moisture absorption part 11, and when located in the outdoor side, it will be called the outdoor side moisture absorption part 12.

  The wall 3 includes an opening 3a (hereinafter, referred to as “upper opening 3a”) in the upper part in the vertical direction, and an opening 3b (hereinafter referred to as “lower opening 3b”) in the lower part in the vertical direction. Yes. The upper end in the vertical direction of the indoor hygroscopic part 11 and the upper end in the vertical direction of the outdoor hygroscopic part 12 are connected at the upper opening 3 a, and the lower end in the vertical direction of the indoor hygroscopic part 11 and the lower end in the vertical direction of the outdoor hygroscopic part 12 are connected. Are connected in the lower opening 3b.

  Although the indoor side moisture absorption part 11 and the outdoor side moisture absorption part 12 can go in and out of the upper opening part 3a and the lower opening part 3b as will be described later, it is preferable to be configured so as to suppress the entry and exit of air. As such a configuration, for example, it may be possible to provide something like a warm bath.

  The indoor hygroscopic part 11 and the outdoor hygroscopic part 12 include a strip-shaped connecting tool 14 having a predetermined width in the horizontal direction and a plurality of hygroscopic materials 13 fixed to each other by the connecting tool 14. The hygroscopic material 13 is a hygroscopic material capable of absorbing and releasing moisture at room temperature. As a specific example of such a hygroscopic material 13, a zeolite-based water vapor adsorbing material (Mitsubishi Resin Co., Ltd., AQSOA (registered trademark)) and the like can be mentioned. The member constituting the connector 14 can be used without particular limitation as long as it can withstand the usage environment of the humidity control system 10 and can fix the plurality of moisture absorbent materials 13. In addition, the form of the connector 14 is not limited to a strip | belt shape, What is necessary is just a form which can fix the some moisture absorbing material 13, For example, a string form may be sufficient.

  Moreover, in FIG. 1, the hygroscopic material 13 is enclosed with the bag-shaped body formed in the cylinder shape with the moisture-permeable material, and this bag-shaped body is arrange | positioned so that a longitudinal direction may become horizontal, and several may be set to a perpendicular direction. The form which is arranged in parallel is illustrated. As the moisture-permeable material, when the moisture-absorbing material 13 is wrapped with the moisture-permeable material, the moisture-absorbing material 13 can absorb moisture in the room, or can absorb moisture in the moisture-absorbing material 13 into the room. If it has, it will not specifically limit. As the moisture permeable material, for example, a moisture permeable cloth or a net-like body can be used.

  Next, the operation of the humidity control system 10 will be described. As described above, the upper end of the indoor hygroscopic part 11 and the upper end of the outdoor hygroscopic part 12 are connected, and the lower end of the indoor hygroscopic part 11 and the lower end of the outdoor hygroscopic part 12 are connected, When the indoor hygroscopic part 11 absorbs moisture and becomes heavier than the outdoor hygroscopic part 12, the indoor hygroscopic part 11 is lowered (by moving the indoor hygroscopic part 11 in the direction of the arrow S shown in FIG. 1). The upper end of the outer moisture absorption unit 12 is drawn into the room from the upper opening 3a, and the lower end of the room side moisture absorption unit 11 is drawn out of the room from the lower opening 3b. On the other hand, when the indoor-side moisture absorption part 11 releases moisture and becomes lighter than the outdoor-side moisture absorption part 12, the outdoor-side moisture absorption part 12 falls (by moving the outdoor-side moisture absorption part 12 in the direction of arrow W shown in FIG. 1). ), The upper end of the indoor moisture absorption part 11 is drawn out of the room from the upper opening 3a, and the lower end of the outdoor moisture absorption part 12 is drawn into the room from the lower opening 3b. Thus, the indoor side moisture absorption part 11 and the outdoor side moisture absorption part 12 are configured in a caterpillar shape so as to be able to go infinitely between the room and the outdoors across the wall 3. In addition, in order to reduce the friction at the time of the indoor moisture absorption part 11 and the outdoor moisture absorption part 12 moving as mentioned above, it is preferable to devise such as providing a pulley.

  Next, operation | movement of the humidity control system 10 when operating the panel radiator 20 is demonstrated in detail.

  In the summer, the surface of the panel radiator 20 is set at a low temperature, so that the surface is condensed, so the humidity around the panel radiator 20 is 100%. Moreover, the indoor side moisture absorption part 11 near the panel radiator 20 is also cooled, and the temperature is low and the humidity is high. The hygroscopic material 13 provided in the room-side hygroscopic part 11 becomes heavier by about 20% by mass when it absorbs moisture. On the other hand, since the outdoor air temperature is high, the hygroscopic material 13 provided in the outdoor hygroscopic part 12 releases moisture, so that the outdoor hygroscopic part 12 is lighter than the indoor hygroscopic part 11. As a result, in order to restore the weight balance between the indoor-side hygroscopic part 11 and the outdoor-side hygroscopic part 12, the indoor-side hygroscopic part 11 and the outdoor-side hygroscopic part 12 move as described above. As described above, the moisture absorption and moisture release of the moisture absorbent material 13 and the movement of the indoor moisture absorption part 11 and the outdoor moisture absorption part 12 are repeated, so that the moisture in the room is released outside the room.

  In winter, the surface of the panel radiator 20 is set at a high temperature, so the humidity around the panel radiator 20 is low. Moreover, the indoor side moisture absorption part 11 near the panel radiator 20 is also heated, so that the temperature becomes high and the humidity is low. Therefore, the hygroscopic material 13 provided in the indoor-side hygroscopic part 11 releases moisture and becomes light. On the other hand, since the outdoor air temperature is low, the hygroscopic material 13 provided in the outdoor hygroscopic part 12 absorbs moisture and is about 20% by weight heavier at the maximum, so the outdoor hygroscopic part 12 is heavier than the indoor hygroscopic part 11. As a result, in order to restore the weight balance between the indoor-side hygroscopic part 11 and the outdoor-side hygroscopic part 12, the indoor-side hygroscopic part 11 and the outdoor-side hygroscopic part 12 move as described above. As described above, the moisture absorption and moisture release of the moisture absorbent material 13 and the movement of the indoor moisture absorbing portion 11 and the outdoor moisture absorbing portion 12 are repeated, so that the outdoor moisture is taken into the room.

  As described above, according to the humidity control system 10, the indoor humidity can be adjusted when the panel radiator 20 is used.

  As explained so far, according to the humidity control system 10, the movement of the indoor side moisture absorption part 11 and the outdoor side moisture absorption part 12 is optimized according to the moisture absorption or moisture release rate of the moisture absorption material. The performance can be maximized. In addition, in order to optimize the performance according to the location (humidity) where the humidity control system 10 is installed, only the volume and material of the moisture absorbent material 13 provided in the indoor moisture absorber 11 and the outdoor moisture absorber 12 are changed. The humidity control performance can be arbitrarily adjusted.

  In addition, the humidity control system 10 can automatically manage the humidity in the room without supplying power from the outside, which is preferable from the viewpoint of energy saving. However, it is possible to provide a function of forcibly moving the indoor moisture absorption unit 11 and the outdoor moisture absorption unit 12 with auxiliary power, or absorbing or dehumidifying using an auxiliary heater or the like.

  Although not shown, in order to prevent intrusion of wind and rain, insects and the like into the room, the outside of the humidity control system 10, particularly the outside of the upper opening 3a and the lower opening 3b is covered with other members. It is preferable that The member that covers the outdoor side of the humidity control system 10 is not particularly limited as long as it can prevent the entry of wind and rain, insects, and the like into the room, but does not prevent the moisture absorbent material 13 from absorbing or releasing moisture. Therefore, it is preferable to have an opening covered with a moisture-permeable member or a net-like member.

  Moreover, although FIG. 1 illustrates a form in which the hygroscopic material 13 is enclosed in a bag-like body formed in a tubular shape with a moisture permeable material, the present invention is not limited to such a form. For example, a form in which a hygroscopic material is enclosed in a bag-like body formed in a spherical shape or a polyhedral shape by a moisture permeable material may be used.

  Moreover, in the description of the present invention so far, the form in which the indoor moisture absorbing part 11 and the outdoor moisture absorbing part 12 are each provided with the moisture absorbing material 13 and the coupling tool 14 is illustrated, but the present invention is not limited to such form. As described above, the indoor hygroscopic part and the outdoor hygroscopic part provided in the humidity control system of the present invention have the vertical upper end of the indoor hygroscopic part and the vertical upper end of the outdoor hygroscopic part at the upper opening of the wall. As long as it is connected, the lower end in the vertical direction of the indoor hygroscopic portion and the lower end in the vertical direction of the outdoor hygroscopic portion may be connected at the lower opening of the wall. For example, as illustrated in FIG. The part and the outdoor moisture absorption part may be configured by a single band-shaped body. FIG. 2A is a view schematically showing a vertical section of the humidity control system 10 ′, and corresponds to FIG. FIG. 2B is a diagram schematically showing a horizontal section of the humidity control system 10 ′, and corresponds to FIG. 2A and 2B, the same components as those shown in FIGS. 1A and 1B are denoted by the same reference numerals, and description thereof is omitted. To do.

  The humidity control system 10 'includes a strip-shaped wall member 13' having hygroscopicity. The wall member 13 'is installed so that a part thereof is disposed on the indoor side and the outdoor side through the upper opening 3a and the lower opening 3b. That is, the indoor side of the wall material 13 ′ becomes the indoor side moisture absorbing portion 11 ′, and the outdoor side of the wall material 13 ′ becomes the outdoor side moisture absorbing portion 12 ′. Furthermore, in the humidity control system 10 ′, the paper surface of FIG. 2A is provided at the four corners of the wall 3 in the vertical section for the purpose of reducing the resistance when the indoor moisture absorbing portion 11 ′ and the outdoor moisture absorbing portion 12 ′ move. A cylindrical body 15 is provided that can freely rotate with an axis extending in the back / front direction as a rotation axis.

  The wall material 13 ′ can be a wall material that is normally used as a building material, but is formed by forming a hygroscopic material into a band shape, or applying or impregnating a hygroscopic material to a band-shaped base material. Is preferred. The moisture absorption / release performance to be satisfied by the moisture absorbent material is the same as that of the moisture absorbent material 13 described above. Since the wall material 13 ′ can be easily provided with a pattern and color and can reduce unevenness, the room-side moisture absorbing portion 11 ′ and the outdoor moisture-absorbing portion 12 ′ are configured by the wall material 13 ′. It becomes easy to make the inner moisture absorption part 11 ′ and the outdoor moisture absorption part 12 ′ excellent in design.

  However, as described above, the humidity control system of the present invention exhibits a humidity control function by making a weight difference between the indoor side moisture absorption part and the outdoor side moisture absorption part by absorbing or releasing moisture by the moisture absorbent. . From the viewpoint of easily increasing the weight difference between the indoor-side hygroscopic part and the outdoor-side hygroscopic part that can be achieved by the hygroscopic material absorbing or releasing moisture, the hygroscopic material provided in the indoor-side hygroscopic part and the outdoor hygroscopic part It is preferable to increase the volume and to increase the area where the hygroscopic material contacts the outside air. From the viewpoint of easily satisfying this condition, it is preferable that the hygroscopic material is enclosed in a bag-like body formed in a cylindrical shape by a moisture permeable material as illustrated in FIG.
