It is desirable that a mechanism is provided.

  In this invention, the outside air intake can be opened and closed arbitrarily according to the season, weather, time, etc. by operating the shielding mechanism provided in the outside air intake for taking in the outside air after dehumidification by the dehumidifier. This makes it possible to take in fresh air reliably and arbitrarily.

  Moreover, in the building of this invention, it is more desirable that the walkway is provided between the said dehumidification apparatus and the outer wall of the said building.

  In this invention, it becomes possible to perform inspection, maintenance, etc. of a dehumidification apparatus using the walkway provided between the dehumidification apparatus and the outer wall of a building. It is also possible to use this corridor as a place of relaxation.

  According to the dehumidifying apparatus and the building of the present invention, a refrigerant such as cold water circulates to cool the louver slats, and the outside air is cooled by passing outside air from the outside of the building between the slats adjacent to each other vertically. Can do. By cooling the outside air in this way, moisture in the outside air is removed, and it is possible to dehumidify the outside air while passing from the outside of the building. Then, by taking the dehumidified outside air inside the building, it becomes possible to make a person in the building feel a refreshing outside air. This makes it possible to reduce the feeling of extreme heat during hot and humid periods such as summer.

  Further, by installing a dehumidifier on the outer periphery of the building so that the dehumidified outside air is taken into the building (inside the room), the air conditioning load on the air conditioner, the external air conditioner, and the like can be reduced. In addition, by arranging a plurality of slats at appropriate intervals above and below, it becomes possible to incorporate soft indirect daylight into the room, and this light can be used as an alternative to ambient lighting.

Further, the slat 5 is formed such that its thickness gradually decreases from the lowermost end 5d at the center in the depth direction T2 toward the front and rear ends 5e, 5f.

  Furthermore, the wing plate 5 of the present embodiment is formed by applying a photocatalyst (hydrophilic photocatalyst) having a superhydrophilic function such as titanium oxide to the surface (the outer surface 5g of the upper surface and the lower surface). In addition, the wing plate 5 is integrally formed with a metal first refrigerant flow pipe 6 having high heat conductivity, for example, and the first refrigerant flow pipe 6 is disposed at the center 5d in the depth direction T2 of the wing board 5. The width direction T1 is extended from the center 5c side toward the one end portion 5a and the other end portion 5b. Further, the slat 5 is provided with a drain water collecting port penetrating from the upper surface to the lower surface at the lowermost end portion 5c at the center in the width direction T1. In addition, the 1st refrigerant | coolant circulation pipe | tube 6 is opened by the drain water collection port, and is each arrange | positioned by this width | variety T1 both sides on both sides of this drain water collection port. Further, as shown in FIG. 1, a drain receiver 7 communicating with the drain water collecting port and a refrigerant discharge pipe 8 connected to the drain receiver 7 are integrally provided on the lower surface side of the lowermost end portion 5 c of the wing plate 5.

  The plurality of blades 5 formed in this way are arranged in parallel in the vertical direction T3 from the upper end side to the lower end side of the frame 4 (louver 2). They are arranged with a predetermined gradient.

  Further, the first refrigerant flow pipe 6 of each slat 5 is connected to a second refrigerant flow pipe 9 disposed on both side ends 5a and 5b of the slat 5 and extending in the vertical direction T3. Yes. In addition, the pair of second refrigerant flow pipes 9 disposed on the both side end portions 5 a and 5 b side of the slats 5 are connected to the lower end sides on the lower end side of the frame 4.

  On the other hand, the refrigerant supply device 3 includes a vertical heat storage tank 10 that temporarily stores a refrigerant W (cold water in the present embodiment) W such as cold water, a refrigerant supply pipe 11, and a feed pump 12. ing. The vertical heat storage tank 10 is connected to the refrigerant discharge pipe 8 provided on the lowermost slat 5 on the upper end side. The refrigerant supply pipe 11 is provided with one end connected to the lower end side of the vertical heat storage tank 10 and the other end connected to the second refrigerant flow pipe 9. The feed pump 12 is interposed between one end and the other end of the refrigerant supply pipe 11.

  The dehumidifier 1 configured as described above is installed on the outer periphery of the building 15 so that the louver 2 is along the outer wall 16 of the building 15 as shown in FIG. The louver 2 is disposed so that the slats 5 are obliquely installed with a predetermined gradient.

  Further, in the building 15 of the present embodiment provided with the dehumidifying device 1 installed in this way, the dehumidifying device 15 and the outer wall 16 are arranged so that the upper surface 17a is arranged on the substantially same horizontal plane as the floor surface F of each floor. A walkway 17 is provided between the two. Such a walkway 17 is formed by using, for example, grating.

  Furthermore, the building 15 of this embodiment is provided with a glass window 18 on the outer wall 16 portion of each floor, and the outer wall 16 portion of each floor has an upper portion (upper wall 16a) than the glass window 16 and a glass window. Outside air intakes 19 are provided in the lower part (lower wall (waist wall) 16b). Further, the outside air intake 19 is provided with a shielding mechanism 20 for opening and closing the outside air intake 19. The shielding mechanism 20 is, for example, a fire damper, a volume damper, a shutter, or the like. Furthermore, a filter 21 is provided in the outside air intake port 19, and a filter having a filter performance according to the purpose is selectively used as the filter 21 from a saran net level to a high-performance filter. .

  Next, the operation and effect of the dehumidifying apparatus 1 of the present embodiment having the above-described configuration and the building 15 including the same will be described.

  In the present embodiment, first, the feed pump 12 of the refrigerant supply device 3 is driven, and the cold water (refrigerant W) stored in the vertical heat storage tank 10 is supplied from the refrigerant supply pipe 11 to the second refrigerant flow pipe 9 and further to the second refrigerant. The refrigerant is supplied from the circulation pipe 9 to the first refrigerant circulation pipe 6 of each slat 5 and circulated. In this way, each wing plate 5 is cooled by circulating the cold water W through the first refrigerant flow pipe 6.

  When each slat 5 and thus the louver 2 are cooled in this way, the outside air 22 passes between the slats 5 adjacent to the top and bottom of the louver 2 from the outside toward the outer wall 16 of the building 15, and The wing plate 5 functions as a heat exchanger to cool the outside air 22, and moisture in the outside air 22 is condensed on the surface 5 g of the wing plate 5 and removed. For this reason, even in a building 15 such as a skyscraper, when a person M in the room drives the shielding mechanism 20 to open the outside air intake port 19, the outside air 22 'dehumidified through the louver 2 is outside air. It is taken into the room through the intake 19. As a result, the person M in the room is dehumidified by the louver 2 (dehumidifying device 1) and feels the soft outside air 22 'that is sequentially taken into the room. Even in a hot and humid period such as summer, for example, the soft outside air 22 'dehumidified by the louver 2 is taken into the room, so that a comfortable air environment is formed and the feeling of extreme heat of the person M in the room is reduced. .

  At this time, since the outside air intake 19 having the shielding mechanism 20 is provided in the upper and lower portions of the outer wall 16 portion of each floor, depending on the winter season, summer season, intermediate season, weather, time, etc. The upper and lower outside air intakes 19 can be selectively opened and closed (depending on conditions), and the soft outside air 22 ′ can be taken into the room from the selectively opened outside air inlet 19.

  Furthermore, in the present embodiment, since the filter 21 is provided in the outside air intake port 19, the dehumidified outside air 22 ′ passes through the filter 21 and, for example, pests, pollen, dust, and other impurities are removed from the outside air 22 ′. The outside air 22 'from which these impurities have been removed is taken into the room.

  The louver 2 installed on the outer periphery of the building 15 also contributes to energy reduction such as air conditioning load and illumination power of the building 15. That is, by incorporating the outside air 22 ′ dehumidified by the louver 2 into the room, the air conditioning load on the air conditioner, the external air conditioner, etc. is reduced particularly in a hot and humid period such as summer. In addition, since the louver 2 is installed on the outer periphery of the building 15 and the outer wall 16 of the building 15 is covered with the louver 2, the air conditioning heat load caused by direct solar radiation of the building 15 is also greatly reduced. Furthermore, since the temperature between the louver 2 and the outer wall 16 of the building 15 is lowered, the air conditioning load due to convective heat transfer is also reduced.

  Further, since the louver 2 is formed by arranging the wing plates 5 adjacent to each other at an appropriate interval, the irradiated sunlight is reflected by the wing plate 5 and is provided on the outer wall 16 of the building 15. Soft indirect daylight S is introduced into the room through the window 18 or the like. For this reason, by using this indirect daylight S as an alternative light for the ambient illumination, the illumination power can be reduced.

  Here, when the outside air 22 is cooled and dehumidified as it passes between the louvers 5 of the louver 2 as described above, moisture taken from the outside air 22 is condensed on the surface 5 g of the wing boards 5. If the condensed water W 'remains on the surface 5g of the slat 5 in the form of water droplets, the slat 5 and the louver 2 may become dirty, and the appearance of the building 15 may be impaired. Further, when rainwater W ″ remains on the surface 5 g of the slats 5 in the form of water droplets during rainfall, the slats 5 and the louvers 2 are also contaminated.

  On the other hand, in this embodiment, since the slats 5 are arranged with a gradient, the dew condensation water W ′ generated on the surface 5d of the slats 5 is the lowermost end of the center of the slats 5 in the width direction T1. The water flows toward the portion 5c and is collected in the drain receiver 7 from the drain water collecting port provided in the lowermost end portion 5c. Also during the rain, like the condensed water W ′, the rain water W ″ on the surface 5 g of the slat 5 flows toward the lowermost end portion 5 c and is collected from the drain collecting port to the drain receiver 7. Furthermore, in this embodiment, since the photocatalyst having a superhydrophilic function is applied to the surface 5g of the slats 5, the dew condensation water W ′ and the rainwater W ″ are in the state of a thin film in the bottom end portion. The water flows down to the 5c side and is collected more reliably. As a result, the dew condensation water W ′ and rainwater W ″ generated on the surface 5 g of the slat 5 are less likely to remain as water droplets, and contamination of the louver 2 is prevented due to the physical characteristics of the photocatalyst. For this reason, maintenance such as cleaning for maintaining the appearance of the building 15 in a suitable state becomes unnecessary, or the maintenance frequency can be reduced.

  Further, in the present embodiment, since the walkway 17 is provided between the dehumidifying device 1 (louver 2) and the outer wall 16 of the building 15, for example, inspection or maintenance of the dehumidifying device 1 is required. However, the operator can easily perform inspections and maintenance by using the walkway 17. In addition, such a walkway 17 can be suitably used as a place of relaxation because the fresh air 22 'is circulated by the dehumidifying device.

  On the other hand, the cold water W after flowing through the first refrigerant flow pipe 6 and cooling each wing plate 5 is discharged from the drain water collecting port to the drain receiver 7. And since the refrigerant | coolant discharge pipe 8 is connected to the drain receptacle 7 provided in each slat | blade 5, the cold water W is returned in the vertical thermal storage tank 10 through the drain receptacle 7 and the refrigerant | coolant discharge pipe 8. FIG. Condensed water W ′ and rain water W ″ collected in the drain receiver 7 are also taken into the vertical heat storage tank 10 through the drain receiver 7 and the refrigerant discharge pipe 8, similarly to the cold water W. Then, heat is exchanged with the outside air 22 through the slats 5, and the cold water W (refrigerant including condensed water W ′ and rainwater W ″) having a high temperature is introduced into the vertical heat storage tank 10. In addition, the refrigerant W stored in the vertical heat storage tank 10 forms a temperature stratification, and the refrigerant W having a high temperature accumulates above and the refrigerant W having a low temperature accumulates below. For this reason, while driving the feed pump 12 and supplying the refrigerant (cold water) W below the vertical heat storage tank 10 to the louver 2, the slat 5 (louver 2) is cooled efficiently and reliably, Refreshing outside air 22 ′ is continuously taken into the room of the building 15.

  Therefore, in the dehumidifying device 1 of the present embodiment and the building 15 equipped with the same, the cold water W (refrigerant) flows to cool the louver 5 of the louver 2, and the slats 5 adjacent to each other up and down from the outside of the building 15. The outside air 22 can be cooled by passing the outside air 22 between them. By cooling the outside air 22 in this way, moisture in the outside air is removed, and it is possible to pass the outside of the building 15 and dehumidify the outside air 22. Then, by introducing the dehumidified outside air 22 ′ inside the building 15, it is possible to make the person M in the room of the building 15 feel a refreshing outside air. This makes it possible to reduce the feeling of extreme heat during hot and humid periods such as summer.

  In addition, by installing the dehumidifying device 1 on the outer periphery of the building 15 and taking the dehumidified outside air 22 ′ into the inside (indoor) of the building 15, the air conditioning load on the air conditioner or the external air conditioner can be reduced. Is possible. Furthermore, by arranging a plurality of slats 5 at an appropriate interval above and below, it becomes possible to incorporate soft indirect daylight S into the room, and this indirect daylight S can be used as an alternative to ambient lighting. Lighting power can be reduced by using it. For this reason, by installing the dehumidifying device 1 on the outer periphery of the building 15, it is possible to reduce a lot of energy such as air conditioning load and illumination power.

  Further, since the slat 5 is provided with a gradient, and the drain collecting port is provided at the lowermost end portion 5c of the slat 5, the condensed water W ′ generated on the surface 5g of the slat 5 Rainwater W ″ adhering to the surface 5 g of the plate 5 flows toward the lowermost end portion 5 c of the wing plate 5 and is discharged from the drain water collecting port. Thereby, the dew condensation water W ′ and the rainwater W ″ do not remain as water droplets on the surface 5 g of the slat 5, and it is possible to suppress (prevent) contamination of the slat 5 and thus the louver 2.

  Further, by applying a hydrophilic photocatalyst to the surface 5 g of the slats 5, the condensed water W ′ and rainwater W ″ generated by dehumidifying the outside air 22 are allowed to flow down in a thin film state. It becomes possible to remove from the surface 5g. As a result, the dew condensation water W ′ and rainwater W ″ generated on the surface 5 g of the slat 5 are less likely to remain as water droplets, and the louver 2 is reliably suppressed (prevented) due to the physical characteristics of the photocatalyst. it can.

  In addition, an outside air inlet 19 for taking in the outside air 22 ′ dehumidified after passing through the dehumidifying device 1 is provided inside the building 15, and the outside air inlet 19 is provided with a shielding mechanism 20. 20 can be operated to open and close the outside air intake 19 arbitrarily according to the season, weather, time and the like. As a result, it is possible to take in the outside air 22 ′ that is surely and arbitrarily refreshed.

  Furthermore, since the filter 21 is provided in the outside air intake port 19, pests, pollen, dust, and other impurities can be removed from the outside air 22 ′ by the filter 21, and the outside air 22 ′ from which the impurities are removed is converted into the building 15. It becomes possible to incorporate inside.

  In addition, the dehumidifying device 1 can be inspected and maintained using the walkway 17 provided between the dehumidifying device 1 and the outer wall 16 of the building 15. It is also possible to use this corridor 15 as a place of relaxation.

  As described above, since the dehumidifying apparatus 1 according to the present embodiment can be used as a functional facade considering the environment, for example, when applied to a building 15 of an SC (solar circuit), the above-described effect is particularly surely and sufficiently obtained. It will be demonstrated.

  As mentioned above, although one embodiment of the dehumidifying device according to the present invention and a building including the dehumidifying device has been described, the present invention is not limited to the above one embodiment, and can be appropriately changed without departing from the gist thereof. is there. For example, in the present embodiment, it is assumed that the refrigerant is cold water W, and the refrigerant supply device 3 includes the vertical heat storage tank 10, the refrigerant supply pipe 11, and the feed pump 12, but the refrigerant W does not necessarily need to use cold water (water), and the refrigerant supply device 3, that is, the cold heat source, is not particularly limited as long as the louver 2 of the dehumidifying device 1 can be cooled. For example, the coolant W may be supplied to the louver 2 (dehumidifier 1) as it is with a water-cooled heat pump or an air-cooled heat pump using drain or other water.
