Description
本発明は、蒸発冷却装置の技術に関する。 The present invention relates to a technique for an evaporative cooling device.
従来、ヒートアイランド現象に対する対応策として、様々な方法が提案されている。 Conventionally, various methods have been proposed as countermeasures against the heat island phenomenon.
例えば、特許文献１では、給水部と、給水部から上部方向に延びるように設けられ、給水部に貯水された水を水面から１ｍ以上の高さに揚水可能な高揚水性多孔質体と、を備える蒸発冷却壁体が提案されている。この冷却壁体によれば、高揚水性多孔質体が吸い上げた水を表面より蒸発させることで周囲の雰囲気を冷却することができる。 For example, in Patent Document 1, a water supply section and a highly water-lifting porous body provided so as to extend upward from the water supply section and capable of pumping water stored in the water supply section to a height of 1 m or more from the water surface are provided. A provided evaporative cooling wall has been proposed. According to this cooling wall body, the surrounding atmosphere can be cooled by evaporating the water sucked up by the highly pumped porous body from the surface.
また、例えば、非特許文献１では、最上段に配置されたルーバーに潅水チューブが入っており、この最上段のルーバーから下位のルーバーに水を滴下する冷却ルーバー装置が提案されている。この冷却ルーバー装置によれば、各ルーバーに滴下した水を蒸発させることで周囲の雰囲気を冷却することができる。 Further, for example, Non-Patent Document 1 proposes a cooling louver device in which an irrigation tube is contained in a louver arranged at the uppermost stage, and water is dropped from the uppermost louver to a lower louver. According to this cooling louver device, the surrounding atmosphere can be cooled by evaporating the water dropped on each louver.
更に、例えば、特許文献２では、ミスト状の水を噴霧するミスト噴霧システムが提案されている。このミスト噴霧システムによれば、噴霧したミスト状の水を蒸発させることで周囲の雰囲気を冷却することができる。 Further, for example, Patent Document 2 proposes a mist spraying system for spraying mist-like water. According to this mist spraying system, the surrounding atmosphere can be cooled by evaporating the sprayed mist-like water.
上記従来の方法について、本件発明者らは、次のような問題点を見出した。すなわち、上記特許文献１で提案される方法では、高揚水性多孔質体の毛管力によって、水の輸送を行っているため、水の輸送範囲が限られてしまい、大型化が困難である。また、上記非特許文献１で提案される方法では、各ルーバーに均一に水を行き渡らせることは難しく、かつ各ルーバーには蒸発する分よりも過剰に水を供給することになるため、周囲の雰囲気を効率的に冷却することが困難である。更に、上記特許文献２で提案される方法では、ミストの到達範囲を制御するのが難しいため、冷却範囲を制御することができず、かつ屋内で使用することができない。したがって、従来の方法では、簡易な構成で、冷却範囲を制御しながら、その範囲の雰囲気を効率よく冷却することが困難である、という問題点があることを本件発明者らは見出した。 Regarding the above-mentioned conventional method, the present inventors have found the following problems. That is, in the method proposed in Patent Document 1, water is transported by the capillary force of the highly pumped porous body, so that the transport range of water is limited and it is difficult to increase the size. Further, in the method proposed in Non-Patent Document 1, it is difficult to uniformly distribute water to each louver, and water is supplied to each louver in excess of the amount of evaporation. It is difficult to cool the atmosphere efficiently. Further, in the method proposed in Patent Document 2, it is difficult to control the reachable range of the mist, so that the cooling range cannot be controlled and the mist cannot be used indoors. Therefore, the present inventors have found that the conventional method has a problem that it is difficult to efficiently cool the atmosphere in the range while controlling the cooling range with a simple configuration.

なお、図１の例では、ヘッドボックス１１には３つの羽根部材１２が取り付けられている。しかしながら、羽根部材１２の数は、このような例に限定されなくてもよく、実施の形態に応じて適宜選択されてよい。羽根部材１２の数は、１つであってもよいし、２つであってもよいし、４つ以上であってもよい。 In the example of FIG. 1, three blade members 12 are attached to the head box 11. However, the number of blade members 12 does not have to be limited to such an example, and may be appropriately selected depending on the embodiment. The number of the blade members 12 may be one, two, or four or more.
次に、図２及び図３を更に用いて、羽根部材１２の構成について説明する。図２及び図３は、本実施形態に係る羽根部材１２を模式的に例示する正面図及び断面図である。図２及び図３に示されるとおり、本実施形態に係る各羽根部材１２は、シート状の防水防湿部材１３とシート状の防水透湿部材１４とを備えている。各羽根部材１２は、本発明の「水保持部材」に相当する。 Next, the configuration of the blade member 12 will be described with reference to FIGS. 2 and 3. 2 and 3 are a front view and a cross-sectional view schematically illustrating the blade member 12 according to the present embodiment. As shown in FIGS. 2 and 3, each blade member 12 according to the present embodiment includes a sheet-shaped waterproof / moisture-proof member 13 and a sheet-shaped waterproof / moisture-permeable member 14. Each blade member 12 corresponds to the "water holding member" of the present invention.
防水防湿部材１３は、水及び水蒸気に対して不透過性を有している。この防水防湿部材１３には、水密性を有する材料を用いることができる。具体例として、防水防湿部材１３には、樹脂、紙、布、木製等を用いることができる。一方、防水透湿部材１４は、水に対して不透過性を有し、かつ水蒸気に対して透過性を有している。この防水透湿部材１４には、例えば、ＷＬゴア＆アソシエイツ社製のゴアテックス（登録商標）、東レ株式会社製のエントラント（登録商標）、小松精練株式会社製のＳＡＩＴＯＳ（登録商標）等を用いることができる。 The waterproof / moisture-proof member 13 is impermeable to water and water vapor. A material having watertightness can be used for the waterproof / moisture-proof member 13. As a specific example, resin, paper, cloth, wood, or the like can be used for the waterproof / moisture-proof member 13. On the other hand, the waterproof / breathable member 14 is impermeable to water and permeable to water vapor. For the waterproof / breathable member 14, for example, Gore-Tex (registered trademark) manufactured by WL Gore & Associates, Entrant (registered trademark) manufactured by Toray Industries, Inc., SAITOS (registered trademark) manufactured by Komatsu Seiren Co., Ltd., etc. are used. be able to.
防水防湿部材１３及び防水透湿部材１４はそれぞれ略矩形状でかつ平らに形成されており、水平方向に互いに対向するように配置されている。そして、防水防湿部材１３及び防水透湿部材１４の上下左右方向の各端部は、各フレーム材１２１〜１２４によって閉じられている。これにより、羽根部材１２は、防水防湿部材１３及び防水透湿部材１４の間に密封された内部空間１６を有するように形成されている。 The waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 are each substantially rectangular and flat, and are arranged so as to face each other in the horizontal direction. The ends of the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 in the vertical and horizontal directions are closed by the frame members 121 to 124. As a result, the blade member 12 is formed so as to have an internal space 16 sealed between the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14.
また、防水防湿部材１３及び防水透湿部材１４の間には、上下方向に延び、左右方向に配列された複数のリブ１５が設けられている。各リブ１５は、防水防湿部材１３及び防水透湿部材１４を溶着、接着等により連結しており、これによって、内部空間１６を左右方向に分割している。 Further, a plurality of ribs 15 extending in the vertical direction and arranged in the horizontal direction are provided between the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14. Each rib 15 connects the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 by welding, adhesion, or the like, thereby dividing the internal space 16 in the left-right direction.
なお、図２及び図３の例では、５つのリブ１５が設けられている。しかしながら、リブ１５の数は、このような例に限定されなくてもよく、実施の形態に応じて適宜選択されてよい。このような複数のリブ１５を備える防水防湿部材１３として、例えば、片段タイプのプラスチックダンボールを利用することができる。このとき、プラスチックダンボールの中芯が各リブ１５に相当する。 In the examples of FIGS. 2 and 3, five ribs 15 are provided. However, the number of ribs 15 does not have to be limited to such an example, and may be appropriately selected depending on the embodiment. As the waterproof / moisture-proof member 13 provided with such a plurality of ribs 15, for example, a single-stage type plastic cardboard can be used. At this time, the core of the plastic cardboard corresponds to each rib 15.
更に、上端部を構成するフレーム材１２１には、ヘッドボックス１１の中空部１１０と羽根部材１２の内部空間１６とを連結する給水経路１２５が設けられている。この給水経路１２５は、本発明の「供給経路」に相当する。この給水経路１２５を介して、羽根部材１２の内部空間１６には、ヘッドボックス１１の中空部１１０から水が供給される。 Further, the frame member 121 forming the upper end portion is provided with a water supply path 125 for connecting the hollow portion 110 of the head box 11 and the internal space 16 of the blade member 12. This water supply path 125 corresponds to the "supply path" of the present invention. Water is supplied from the hollow portion 110 of the head box 11 to the internal space 16 of the blade member 12 via the water supply path 125.
一方、下端部を構成するフレーム材１２４から左側端部を構成するフレーム材１２３を通ってフレーム材１２１にかけて、排水経路１２６が設けられている。内部空間１６内の不要な水は、この排水経路１２６を通って、ヘッドボックス１１の中空部１１０に排出される。なお、この排水経路１２６は、内部空間１６内の空気抜きにも利用可能である。 On the other hand, a drainage path 126 is provided from the frame material 124 forming the lower end portion to the frame material 121 through the frame material 123 forming the left end portion. Unwanted water in the internal space 16 is discharged to the hollow portion 110 of the head box 11 through the drainage path 126. The drainage path 126 can also be used for venting air in the internal space 16.
§２ 使用方法
次に、本実施形態に係るルーバー装置１の使用方法について説明する。このルーバー装置１は、例えば、屋外、半屋外空間（例えば、カフェのテラス席）、室内の窓付近、ダブルスキンの外壁とガラス材との間の領域（以下、「ダブルスキン構造内」と記載する）等に配置して、日光を遮蔽するのに利用することができる。このとき、ルーバー装置１を、防水防湿部材１３が日光に当たるように配置してもよいし、防水透湿部材１４が日光に当たるように配置してもよい。
§2 Usage method Next, the usage method of the louver device 1 according to the present embodiment will be described. The louver device 1 is described as, for example, an outdoor area, a semi-outdoor space (for example, a terrace seat of a cafe), an area near an indoor window, and an area between a double-skin outer wall and a glass material (hereinafter, referred to as “inside a double-skin structure”). It can be used to shield sunlight by arranging it in such a place. At this time, the louver device 1 may be arranged so that the waterproof / moisture-proof member 13 is exposed to sunlight, or the waterproof / moisture-permeable member 14 may be arranged so as to be exposed to sunlight.
ルーバー装置１を利用場所に配置した後、ヘッドボックス１１の中空部１１０及び給水経路１２５を介して水供給源から各羽根部材１２の内部空間１６に水を供給する。これにより、各羽根部材１２は、内部空間１６に水を保持した状態になる。防水防湿部材１３は水及び水蒸気に対して不透過性を有しているため、内部空間１６に貯留される水は、内部空間１６に隣接する防水防湿部材１３から外部に放出されない。一方、防水透湿部材１４は、水に対して不透過性を有しているものの、水蒸気に対して透過性を有しているため、内部空間１６に貯留される水は、内部空間１６に隣接する防水透湿部材１４から水蒸気の状態で外部に放出される。このとき、防水透湿部材１４では、水の蒸発に伴い、周囲の雰囲気の熱を蒸発潜熱に転換することができる。これにより、周囲の雰囲気を冷却することができる。 After arranging the louver device 1 at the place of use, water is supplied from the water supply source to the internal space 16 of each blade member 12 via the hollow portion 110 of the head box 11 and the water supply path 125. As a result, each blade member 12 is in a state of holding water in the internal space 16. Since the waterproof / moisture-proof member 13 is impermeable to water and water vapor, the water stored in the internal space 16 is not discharged to the outside from the waterproof / moisture-proof member 13 adjacent to the internal space 16. On the other hand, although the waterproof / breathable member 14 is impermeable to water, it is permeable to water vapor, so that the water stored in the internal space 16 is stored in the internal space 16. It is discharged to the outside in the state of water vapor from the adjacent waterproof / breathable member 14. At this time, the waterproof / breathable member 14 can convert the heat of the surrounding atmosphere into latent heat of vaporization as the water evaporates. As a result, the surrounding atmosphere can be cooled.
ここで、本実施形態では、防水防湿部材１３及び防水透湿部材１４の間に上下方向に延びる複数のリブ１５が水平方向に配列されており、これらの複数のリブ１５によって、内部空間１６は複数の部分空間に分割されている。そのため、本実施形態では、給水経路１２５から供給される水を各部分空間に分割して流れるようにすることができる。これにより、防水透湿部材１４の広い範囲に水を行き渡らせ易くすることができる。したがって、本実施形態によれば、防水透湿部材１４の広い範囲で気化熱による冷却効果が生じるようにすることができるため、周囲の雰囲気を効率的に冷却することができる。 Here, in the present embodiment, a plurality of ribs 15 extending in the vertical direction are arranged in the horizontal direction between the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14, and the internal space 16 is formed by the plurality of ribs 15. It is divided into multiple subspaces. Therefore, in the present embodiment, the water supplied from the water supply path 125 can be divided into each subspace and flow. This makes it easier to distribute water over a wide range of the waterproof / breathable member 14. Therefore, according to the present embodiment, the cooling effect of the heat of vaporization can be generated in a wide range of the waterproof / breathable member 14, so that the surrounding atmosphere can be efficiently cooled.
なお、防水防湿部材１３及び防水透湿部材１４の少なくとも一方に比較的に柔らかい素材を利用した場合、内部空間１６に貯留する水の水圧によって、各羽根部材１２の形状が変形する可能性がある。これに対して、本実施形態では、防水防湿部材１３及び防水透湿部材１４を各リブ１５で連結しているため、このような羽根部材１２の変形を抑制することができる。すなわち、各リブ１５は、羽根部材１２の形状保持手段として機能することができる。 When a relatively soft material is used for at least one of the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14, the shape of each blade member 12 may be deformed by the water pressure of the water stored in the internal space 16. .. On the other hand, in the present embodiment, since the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 are connected by the ribs 15, such deformation of the blade member 12 can be suppressed. That is, each rib 15 can function as a means for maintaining the shape of the blade member 12.
また、防水防湿部材１３は、防水透湿部材１４側で生じる水の蒸発により間接的に冷却される。このとき、防水防湿部材１３側を効率的に冷却する、すなわち、防水防湿部材１３及び防水透湿部材１４の両側で温度差が大きくならないようにするためには、防水防湿部材１３及び防水透湿部材１４の間の幅を１ｍｍ〜１０ｍｍに抑えるのが好ましい。 Further, the waterproof / moisture-proof member 13 is indirectly cooled by the evaporation of water generated on the waterproof / moisture-permeable member 14 side. At this time, in order to efficiently cool the waterproof / moisture-proof member 13 side, that is, to prevent the temperature difference between the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 from becoming large, the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 13 are prevented from becoming large. It is preferable to limit the width between the members 14 to 1 mm to 10 mm.
ここで、以下の条件の下で、ルーバー装置１を配置した場合に、防水透湿部材１４側の温度及び防水透湿部材１４と防水防湿部材１３との間で生じる温度差を試算した。その結果、防水透湿部材１４側の温度は気温に対して７℃低下すること、及び防水防湿部材１３及び防水透湿部材１４の間の幅を５ｍｍに設定することで、防水防湿部材１３及び防水透湿部材１４の間の温度差を０．５℃に抑えることができることが分かった。
＜試算条件＞

・防水防湿部材１３側の相対湿度：５０％
・防水透湿部材１４側の気温および平均放射温度：３０℃

・防水透湿部材１４側の湿気伝達率：５．６７×１０-8ｋｇ／（ｍ2・ｓ・Ｐａ）
・防水防湿部材１３および防水透湿部材１４の熱抵抗：１０．０×１０-3（ｍ2・Ｋ）／Ｗ
・防水透湿部材１４の透湿抵抗：１．１９×１０-3（（ｍ2・ｓ・Ｐａ）／ｋｇ
・水の熱伝導率：０．５８２Ｗ／（ｍ・Ｋ）
・水の蒸発潜熱：２５００ｋＪ／ｋｇ
Here, when the louver device 1 is arranged under the following conditions, the temperature on the waterproof / moisture permeable member 14 side and the temperature difference between the waterproof / moisture permeable member 14 and the waterproof / moisture proof member 13 are estimated. As a result, the temperature on the waterproof / moisture permeable member 14 side is lowered by 7 ° C. with respect to the air temperature, and the width between the waterproof / moisture proof member 13 and the waterproof / moisture permeable member 14 is set to 5 mm. It was found that the temperature difference between the waterproof and breathable members 14 can be suppressed to 0.5 ° C.

また、防水透湿部材１４側に日射が当たり４８０Ｗ／ｍ2の熱が吸収される場合には、防水防湿部材１３及び防水透湿部材１４の間の幅が小さいと、防水透湿部材１４側の日射熱が防水防湿部材１３に伝わることが懸念される。しかしながら、防水透湿部材１４側は水の蒸発により効果的に冷却されるので、防水防湿部材１３及び防水透湿部材１４の間の幅が５ｍｍの場合でも、防水防湿部材１３は気温に対して２．７℃の上昇しか生じず、幅を小さくすることによる温度上昇への影響は小さいことも分かった。なお、防水透湿部材１４側で蒸発が無い場合には、防水防湿部材１３は気温に対して１８．６℃も上昇してしまう。 Further, when the heat of 480 W / m 2 is absorbed by the waterproof / moisture permeable member 14 side, if the width between the waterproof / moisture proof member 13 and the waterproof / moisture permeable member 14 is small, the waterproof / moisture permeable member 14 side. There is a concern that the solar heat will be transmitted to the waterproof / moisture-proof member 13. However, since the waterproof / moisture permeable member 14 side is effectively cooled by the evaporation of water, even when the width between the waterproof / moisture permeable member 13 and the waterproof / moisture permeable member 14 is 5 mm, the waterproof / moisture proof member 13 is exposed to the temperature. It was also found that only an increase of 2.7 ° C occurred, and the effect of reducing the width on the temperature increase was small. If there is no evaporation on the waterproof / moisture permeable member 14 side, the waterproof / moisture proof member 13 will rise by 18.6 ° C. with respect to the air temperature.
［特徴］
以上のとおり、本実施形態に係るルーバー装置１によれば、防水透湿部材１４付近で生じる水の蒸発によって、周囲の雰囲気を冷却することができる。ここで、ルーバー装置１の各羽根部材１２は、防水防湿部材１３及び防水透湿部材１４を用いた簡易な構成で実現される。また、防水透湿部材１４の配置に基づいて、冷却範囲を制御することができる。更に、内部空間１６に貯留した水を利用するため、水を常時滴下しなくてもよく、周囲の雰囲気を効率的に冷却することができる。したがって、本実施形態に係るルーバー装置１によれば、簡易な構成で、冷却範囲を制御し、かつその範囲の雰囲気を効率よく冷却することができる。
[Feature]
As described above, according to the louver device 1 according to the present embodiment, the surrounding atmosphere can be cooled by the evaporation of water generated in the vicinity of the waterproof / breathable member 14. Here, each blade member 12 of the louver device 1 is realized by a simple configuration using the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14. Further, the cooling range can be controlled based on the arrangement of the waterproof / breathable member 14. Further, since the water stored in the internal space 16 is used, it is not necessary to constantly drop the water, and the surrounding atmosphere can be efficiently cooled. Therefore, according to the louver device 1 according to the present embodiment, the cooling range can be controlled and the atmosphere in the range can be efficiently cooled with a simple configuration.
また、本実施形態に係るルーバー装置１は、従来のミスト噴霧等とは相違し、水滴を周囲に飛散するものではない。そのため、比較的に場所を制限されることなく、ルーバー装置１を配置することができる。例えば、窓付近、ダブルスキン構造内、ペリメータゾーン等の室内の窓辺空間にルーバー装置１を配置することができる。 Further, the louver device 1 according to the present embodiment is different from the conventional mist sprayer and the like, and does not scatter water droplets to the surroundings. Therefore, the louver device 1 can be arranged without being relatively limited in location. For example, the louver device 1 can be arranged near a window, in a double-skin structure, or in a window space in a room such as a perimeter zone.
更に、本実施形態に係るルーバー装置１は、周囲の雰囲気の熱を蒸発潜熱に転換する。そのため、ルーバー装置１をダブルスキン構造内に配置することで、建物外に排気されるダブルスキン構造内の空気を冷却することができる。これにより、ヒートアイランド現象の一因となっている建物から都市大気への顕熱放散を低減することができる。 Further, the louver device 1 according to the present embodiment converts the heat of the surrounding atmosphere into latent heat of vaporization. Therefore, by arranging the louver device 1 in the double-skin structure, the air in the double-skin structure exhausted to the outside of the building can be cooled. This makes it possible to reduce the sensible heat dissipation from the building to the urban atmosphere, which is one of the causes of the heat island phenomenon.
§３ 変形例
以上、本発明の実施形態を詳細に説明してきたが、前述までの説明はあらゆる点において本発明の例示に過ぎない。本発明の範囲を逸脱することなく種々の改良や変形を行うことができることは言うまでもない。例えば、以下のような変更が可能である。なお、以下では、上記実施形態と同様の構成要素に関しては同様の符号を用い、上記実施形態と同様の点については、適宜説明を省略した。以下の変形例は適宜組み合わせ可能である。
§3 Modifications Although the embodiments of the present invention have been described in detail above, the above description is merely an example of the present invention in all respects. Needless to say, various improvements and modifications can be made without departing from the scope of the present invention. For example, the following changes can be made. In the following, the same reference numerals will be used for the same components as those in the above embodiment, and the same points as in the above embodiment will be omitted as appropriate. The following modifications can be combined as appropriate.
＜３．１＞
例えば、上記実施形態に係るルーバー装置１は、縦ブラインドとして構成されている。しかしながら、ルーバー装置１のタイプは、縦ブラインドに限られなくてもよい。例えば、各羽根部材１２を水平方向に向けた状態で上下方向に並べることで、ルーバー装置１は、横ブラインドとして構成されてよい。
<3.1>
For example, the louver device 1 according to the above embodiment is configured as a vertical blind. However, the type of louver device 1 does not have to be limited to vertical blinds. For example, the louver device 1 may be configured as a horizontal blind by arranging the blade members 12 in the vertical direction while facing the horizontal direction.
また、上記実施形態では、ルーバー装置１の使用方法として、日光の当たる場所に配置して、周囲の雰囲気を冷却するのに利用する形態を説明した。しかしながら、上記実施形態に係るルーバー装置１の利用形態は、このような例に限定されなくてもよい。上記実施形態に係るルーバー装置１は、防水透湿部材１４から水蒸気を外部に放出する。そのため、例えば、湿度の低い場所に配置することで、ルーバー装置１を加湿器として利用してもよい。 Further, in the above-described embodiment, as a method of using the louver device 1, a mode of arranging the louver device 1 in a place exposed to sunlight and using it for cooling the surrounding atmosphere has been described. However, the usage mode of the louver device 1 according to the above embodiment is not limited to such an example. The louver device 1 according to the above embodiment releases water vapor from the waterproof / breathable member 14 to the outside. Therefore, for example, the louver device 1 may be used as a humidifier by arranging it in a place where the humidity is low.
また、上記実施形態では、ヘッドボックス１１の中空部１１０を介して、各羽根部材１２の内部空間１６に水を供給している。しかしながら、水の供給方法は、このような例に限られなくてもよい。例えば、給水経路１２５に通じる開口をフレーム材１２１に設けてもよい。この場合、この開口を通じて内部空間１６に水を供給することができる。 Further, in the above embodiment, water is supplied to the internal space 16 of each blade member 12 via the hollow portion 110 of the head box 11. However, the method of supplying water does not have to be limited to such an example. For example, the frame material 121 may be provided with an opening leading to the water supply path 125. In this case, water can be supplied to the internal space 16 through this opening.
＜３．２＞
また、上記実施形態では、各羽根部材１２の各リブ１５は、上下方向に延びている。しかしながら、各リブ１５の延びる方向は、同一方向であれば、上下方向に限られなくてもよく、上下方向に対してやや傾いていてもよい。ここで、「同一方向」とは、各リブ１５の延びる方向が完全に一致している状態の他、各リブ１５が重ならない程度に各リブ１５の延びる方向がややずれている状態を含んでもよい。
<3.2>
Further, in the above embodiment, each rib 15 of each blade member 12 extends in the vertical direction. However, the extending direction of each rib 15 is not limited to the vertical direction as long as it is the same direction, and may be slightly inclined with respect to the vertical direction. Here, the "same direction" includes a state in which the extending directions of the ribs 15 are completely the same, and a state in which the extending directions of the ribs 15 are slightly deviated to the extent that the ribs 15 do not overlap. Good.
＜３．３＞
また、上記実施形態では、それぞれ略矩形状の平らな防水防湿部材１３及び防水透湿部材１４が１つずつ前後方向に配置されている。しかしながら、防水防湿部材１３及び防水透湿部材１４の数は、１つに限られなくてもよく、複数であってもよい。
<3.3>
Further, in the above embodiment, one substantially rectangular flat waterproof / moisture-proof member 13 and one waterproof / moisture-permeable member 14 are arranged in the front-rear direction. However, the number of the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 is not limited to one, and may be plural.
図４は、防水防湿部材１３及び防水透湿部材１４を２つずつ備える羽根部材１２Ａを模式的に例示する。図４に例示される羽根部材１２Ａは、上記実施形態に係る羽根部材１２の防水防湿部材１３及び防水透湿部材１４の組を２つ形成し、作成した各組を防水防湿部材１３側で貼り合わせることにより、作成することができる。この羽根部材１２Ａによれば、両防水透湿部材１４の配置される前後方向（図４の左右方向）の両側で、水蒸気を放出し、周囲の雰囲気を冷却することができる。 FIG. 4 schematically illustrates a blade member 12A including two waterproof / moisture-proof members 13 and two waterproof / moisture-permeable members 14. The blade member 12A illustrated in FIG. 4 forms two sets of the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 of the blade member 12 according to the above embodiment, and each of the created sets is attached to the waterproof / moisture-proof member 13 side. It can be created by matching. According to the blade member 12A, water vapor can be released on both sides in the front-rear direction (horizontal direction in FIG. 4) where both waterproof and breathable members 14 are arranged to cool the surrounding atmosphere.
＜３．４＞
また、上記実施形態では、各リブ１５によって、羽根部材１２の形状が保持される。しかしながら、各リブ１５は省略されてもよい。また、各羽根部材１２は、リブ以外の形状保持手段を備えてもよい。
<3.4>
Further, in the above embodiment, the shape of the blade member 12 is maintained by each rib 15. However, each rib 15 may be omitted. Further, each blade member 12 may be provided with a shape holding means other than the rib.
図５は、リブ以外の形状保持手段を備える羽根部材の一例を模式的に例示する。具体的には、図５に示される羽根部材１２Ｂでは、防水防湿部材１３及び防水透湿部材１４が、キルティング模様のように互いに格子状に連結されている。この格子状の連結（図５の点線で示す部分）が、形状保持手段に相当する。防水防湿部材１３及び防水透湿部材１４の連結方法には、例えば、溶着、接着等を用いることができる。 FIG. 5 schematically illustrates an example of a blade member provided with a shape-retaining means other than the rib. Specifically, in the blade member 12B shown in FIG. 5, the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 are connected to each other in a grid pattern like a quilting pattern. This grid-like connection (the portion shown by the dotted line in FIG. 5) corresponds to the shape holding means. For example, welding, adhesion, or the like can be used as a method of connecting the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14.
このように、防水防湿部材１３及び防水透湿部材１４を格子状に連結することで、羽根部材１２Ｂの変形を抑制することができる。また、防水防湿部材１３及び防水透湿部材１４の間の幅が大きくなり過ぎるのを防ぐことができ、これにより、内部空間１６に貯留する水が防水透湿部材１４の広い範囲に接するようにすることができる。したがって、当該変形例によれば、防水透湿部材１４の広い範囲に水を行き渡らせて、その範囲で水の蒸発が生じるようにすることができるため、周囲の雰囲気を効率的に冷却することができる。 By connecting the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 in a grid pattern in this way, deformation of the blade member 12B can be suppressed. Further, it is possible to prevent the width between the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 from becoming too large, so that the water stored in the internal space 16 comes into contact with a wide range of the waterproof / moisture-permeable member 14. can do. Therefore, according to the modification, water can be spread over a wide range of the waterproof / breathable member 14 so that water evaporates in that range, so that the surrounding atmosphere can be efficiently cooled. Can be done.
＜３．５＞
また、上記実施形態では、防水防湿部材１３及び防水透湿部材１４は平らに形成されている。しかしながら、防水防湿部材１３及び防水透湿部材１４の形状は、このような例に限定されなくてもよく、実施の形態に応じて適宜選択されてよい。
<3.5>
Further, in the above embodiment, the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 are formed flat. However, the shapes of the waterproof / moisture-proof member 13 and the waterproof / moisture-permeable member 14 do not have to be limited to such an example, and may be appropriately selected according to the embodiment.
図６及び図７は、平らではない形状を有する防水防湿部材及び防水透湿部材を備える羽根部材の一例を模式的に例示する断面図である。図６及び図７に示される羽根部材１２Ｃは、四角筒状に形成されている。具体的には、防水防湿部材１３Ｃ及び防水透湿部材１４Ｃが四角筒状に形成されている。防水防湿部材１３Ｃは、防水透湿部材１４Ｃよりも断面形状が小さくなっており、羽根部材１２Ｃの内壁を構成している。一方、外側に配置される防水透湿部材１４Ｃは、羽根部材１２Ｃの外壁を構成している。防水防湿部材１３Ｃ及び防水透湿部材１４Ｃの上下方向の両端は適宜閉じられており、これによって、防水防湿部材１３Ｃ及び防水透湿部材１４Ｃの間には四角筒状の内部空間１６Ｃが形成されている。また、防水防湿部材１３Ｃの内側には四角柱状の中空部１７Ｃが形成されている。 6 and 7 are cross-sectional views schematically illustrating an example of a blade member including a waterproof / moisture-proof member having a non-flat shape and a waterproof / moisture-permeable member. The blade member 12C shown in FIGS. 6 and 7 is formed in a square tubular shape. Specifically, the waterproof / moisture-proof member 13C and the waterproof / moisture-permeable member 14C are formed in a square tubular shape. The waterproof / moisture-proof member 13C has a smaller cross-sectional shape than the waterproof / moisture-permeable member 14C, and constitutes the inner wall of the blade member 12C. On the other hand, the waterproof / breathable member 14C arranged on the outside constitutes the outer wall of the blade member 12C. Both ends of the waterproof / moisture-proof member 13C and the waterproof / moisture-permeable member 14C in the vertical direction are appropriately closed, whereby a square tubular internal space 16C is formed between the waterproof / moisture-proof member 13C and the waterproof / moisture-permeable member 14C. There is. Further, a square columnar hollow portion 17C is formed inside the waterproof / moisture-proof member 13C.
なお、羽根部材１２Ｃ（防水防湿部材１３Ｃ及び防水透湿部材１４Ｃ）の形状は、四角筒状に限られなくてもよく、実施の形態に応じて適宜選択されてよい。羽根部材１２Ｃの形状は筒状であれば、本変形例と同様の構成を実現することができる。このとき、防水防湿部材１３Ｃ及び防水透湿部材１４Ｃの形状は、一致していなくてもよい。例えば、防水防湿部材１３Ｃを円筒状とし、防水透湿部材１４Ｃを四角筒状としてもよい。 The shape of the blade member 12C (waterproof / moisture-proof member 13C and waterproof / moisture-permeable member 14C) does not have to be limited to a square cylinder, and may be appropriately selected depending on the embodiment. If the shape of the blade member 12C is tubular, the same configuration as in this modification can be realized. At this time, the shapes of the waterproof / moisture-proof member 13C and the waterproof / moisture-permeable member 14C do not have to match. For example, the waterproof / moisture-proof member 13C may have a cylindrical shape, and the waterproof / moisture-permeable member 14C may have a square tubular shape.
この羽根部材１２Ｃによれば、外壁の全周方向に冷却を実施することができる。したがって、この羽根部材１２Ｃを備えるルーバー装置は、比較的に高い冷却性能が求められ、かつ冷却に利用した水蒸気を建物外に放出可能なダブルスキン構造内に配置するのに適している。 According to the blade member 12C, cooling can be performed in the entire circumferential direction of the outer wall. Therefore, the louver device provided with the blade member 12C is required to have relatively high cooling performance, and is suitable for arranging the louver device in a double-skin structure capable of releasing the water vapor used for cooling to the outside of the building.
ここで、この変形例では、羽根部材１２Ｃの外部に放出される水蒸気の量が多くなる傾向にある。多くの水蒸気が室内に拡散すると、空調の潜熱負荷が大きくなってしまう可能性がある。そこで、これを防ぐべく、図７に示すとおり、ガラス材、ビニール材等の外周材１８で、水蒸気が周囲に拡散するのを防止するために各羽根部材１２Ｃの周囲を覆ってもよい。なお、図７の例では、複数の羽根部材１２Ｃを一度に外周材１８で覆っている。しかしながら、外周材１８で羽根部材１２Ｃを覆う方法は、このような例に限定されなくてもよく、個々の羽根部材１２Ｃを外周材１８で覆ってもよい。 Here, in this modification, the amount of water vapor released to the outside of the blade member 12C tends to increase. If a large amount of water vapor diffuses into the room, the latent heat load of the air conditioner may increase. Therefore, in order to prevent this, as shown in FIG. 7, an outer peripheral material 18 such as a glass material or a vinyl material may cover the periphery of each blade member 12C in order to prevent water vapor from diffusing to the surroundings. In the example of FIG. 7, a plurality of blade members 12C are covered with the outer peripheral material 18 at a time. However, the method of covering the blade member 12C with the outer peripheral material 18 is not limited to such an example, and individual blade members 12C may be covered with the outer peripheral material 18.
また、図８に示すとおり、上記防水防湿部材１３Ｃ及び防水透湿部材１４Ｃの配置は反対であってもよい。図８は、当該変形例に係る羽根部材１２Ｄを模式的に例示する断面図である。図８に示される羽根部材１２Ｄでは、防水透湿部材１４Ｄが、防水防湿部材１３Ｄよりも断面形状が小さくなっている。これにより、防水透湿部材１４Ｄが羽根部材１２Ｄの内壁を構成しており、防水防湿部材１３Ｄが羽根部材１２Ｄの外壁を構成している。防水防湿部材１３Ｄ及び防水透湿部材１４Ｄの間には四角筒状の内部空間１６Ｄが形成されており、防水透湿部材１４Ｄの内側には四角柱状の中空部１７Ｄが形成されている。 Further, as shown in FIG. 8, the arrangement of the waterproof / moisture-proof member 13C and the waterproof / moisture-permeable member 14C may be reversed. FIG. 8 is a cross-sectional view schematically illustrating the blade member 12D according to the modified example. In the blade member 12D shown in FIG. 8, the waterproof / breathable member 14D has a smaller cross-sectional shape than the waterproof / moisture-proof member 13D. As a result, the waterproof / breathable member 14D constitutes the inner wall of the blade member 12D, and the waterproof / moisture-proof member 13D constitutes the outer wall of the blade member 12D. A square tubular internal space 16D is formed between the waterproof / moisture-proof member 13D and the waterproof / moisture-permeable member 14D, and a square columnar hollow portion 17D is formed inside the waterproof / moisture-permeable member 14D.
なお、羽根部材１２Ｄ（防水防湿部材１３Ｄ及び防水透湿部材１４Ｄ）の形状も、上記羽根部材１２Ｃと同様に、四角筒状に限られなくてもよく、実施の形態に応じて適宜選択されてよい。羽根部材１２Ｄの形状は筒状であれば、本変形例と同様の構成を実現することができる。このとき、防水防湿部材１３Ｄ及び防水透湿部材１４Ｄの形状は、一致していなくてもよい。例えば、防水防湿部材１３Ｄを四角筒状とし、防水透湿部材１４Ｃを円筒状としてもよい。 The shape of the blade member 12D (waterproof / moisture-proof member 13D and waterproof / moisture-permeable member 14D) may not be limited to a square cylinder shape as in the case of the blade member 12C, and may be appropriately selected according to the embodiment. Good. If the shape of the blade member 12D is tubular, the same configuration as in this modification can be realized. At this time, the shapes of the waterproof / moisture-proof member 13D and the waterproof / moisture-permeable member 14D do not have to match. For example, the waterproof / moisture-proof member 13D may have a square tubular shape, and the waterproof / moisture-permeable member 14C may have a cylindrical shape.
この羽根部材１２Ｄによれば、外壁を構成する防水防湿部材１３Ｄで日射を吸収し、冷却に利用した水蒸気を中空部１７Ｄ側に排出するようにすることができる。これにより、放出される水蒸気が室内に拡散するのを防止することができる。なお、この変形例では、防水防湿部材１３を日に当たるように配置する上記形態と同様に、防水防湿部材１３Ｄ及び防水透湿部材１４Ｄの間の幅は、１ｍｍ〜１０ｍｍに抑えるのが好ましい。 According to the blade member 12D, the waterproof / moisture-proof member 13D constituting the outer wall can absorb the sunlight and discharge the water vapor used for cooling to the hollow portion 17D side. This makes it possible to prevent the released water vapor from diffusing into the room. In this modified example, the width between the waterproof / moisture-proof member 13D and the waterproof / moisture-permeable member 14D is preferably suppressed to 1 mm to 10 mm, as in the above-described embodiment in which the waterproof / moisture-proof member 13 is arranged so as to be exposed to the sun.
また、図９は、本変形例に係る羽根部材１２Ｄの下端側にファン１９を配置した形態を例示する。このファン１９により、中空部１７Ｄ内を下方向から上方向に通風することができる。そこで、この羽根部材１２Ｄの上端部を、排気ダクトを有するヘッドボックスに取り付けることで、中空部１７Ｄ側に放出された水蒸気が、排気ダクトを介して排出されるようにしてもよい。なお、ファン１９は、排気ダクト内に配置してもよい。 Further, FIG. 9 illustrates a form in which the fan 19 is arranged on the lower end side of the blade member 12D according to this modification. The fan 19 can ventilate the inside of the hollow portion 17D from the lower direction to the upper direction. Therefore, by attaching the upper end portion of the blade member 12D to a head box having an exhaust duct, the water vapor released to the hollow portion 17D side may be discharged through the exhaust duct. The fan 19 may be arranged in the exhaust duct.
