高層建築物の非常階段や屋上などでは、直射日光が当たることを避けるとともに通気性を確保するため、複数の細長い板（羽板）を間隔を開けて複数枚平行に組んだルーバーが設けられている。また、ルーバーは、屋上などに置かれた空調の室外機や水のタンクなどを目隠しするためにも利用されている。
近年、環境問題に対する社会的関心の高まりもあって、このような建物用ルーバーの羽板に太陽電池を組み込んだルーバー型太陽電池ユニットも開発されている（特許文献１参照）。
On high-rise buildings such as emergency stairs and rooftops, louvers are installed in which multiple strips (blades) are assembled in parallel to avoid direct sunlight and to ensure ventilation. Yes. The louvers are also used to blindfold air conditioning outdoor units and water tanks placed on the rooftop.
In recent years, due to increasing social interest in environmental problems, a louver type solar cell unit in which a solar cell is incorporated in the slats of such a building louver has also been developed (see Patent Document 1).
しかし、現在市販されている太陽電池の発電効率は高くても２０％程度であり、太陽エネルギーの有効利用が課題となっている。ルーバー表面に太陽電池パネルを設置した場合でも、発電に利用されない大部分の太陽エネルギーは熱に変わってしまうため、ルーバーの設置によりその周囲の温度が上昇してしまうという問題がある。また、現在、普及している結晶シリコン型の太陽電池は高温になると発電効率が低下するという問題も起きている。 However, the power generation efficiency of solar cells currently on the market is about 20% at the highest, and effective use of solar energy is a problem. Even when a solar cell panel is installed on the surface of the louver, most of the solar energy that is not used for power generation is changed into heat, so that there is a problem that the surrounding temperature rises due to the installation of the louver. In addition, there is a problem that the power generation efficiency of a crystalline silicon solar cell that is currently popular is lowered when the temperature becomes high.
そこで、本発明者らは、上記の従来技術の問題点を解決し、太陽エネルギーをより効率的に利用することを目的として、ルーバーユニットの構造について検討し、鋭意研究開発を行い、本発明の完成に至った。 Therefore, the present inventors have studied the structure of the louver unit, conducted intensive research and development for the purpose of solving the above-mentioned problems of the prior art and using solar energy more efficiently. Completed.

The louver body (2) has a bottom surface portion (12) and a side surface portion (11), and the hollow structure portion (5) is formed by the surface portion (1) and the louver body (2). The building louver unit is provided in the space portion (13) and provided in close contact with the back surface of the surface portion or with a gap.
本発明によれば、その構造中に流体の流路を設け、さらに流体への熱移動が効率的に行われる構成とすることで、より多くの太陽エネルギーを利用できる建物用ルーバーユニットが提供される。本発明のルーバーユニットを利用することで、太陽エネルギーを多面的に利用した優れた光熱ハイブリッドシステムを提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the flow path of the fluid is provided in the structure, and also it is set as the structure by which the heat transfer to a fluid is performed efficiently, The building louver unit which can utilize more solar energy is provided. The By using the louver unit of the present invention, it is possible to provide an excellent photothermal hybrid system that uses solar energy in many ways.
次に、本発明を実施するための好ましい形態を、図面を参照しながら説明する。
図１は、本発明の実施形態の１態様の断面図である。本発明のルーバーユニットは、表面部（１）と、該表面部を支持するルーバー本体（２）と、流体を通過させるための中空構造部（５）とを有する。表面部（１）とは、ルーバーユニットのうち太陽光の受光面にあたる部分をいう。表面部（１）は、ルーバー本体（２）とは別に製造したものを、ルーバー本体（２）に固定してもよいが、図１に示すようにルーバー本体（２）と一体成形してもよい。また、表面部（１）は、図３に示すように太陽電池パネル（７）で形成してもよい。太陽電池パネル（７）は、例えば、複数の太陽電池セルが並べられたもので、市販のものを使用することができる。
Next, preferred modes for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of one aspect of an embodiment of the present invention. The louver unit of the present invention has a surface portion (1), a louver body (2) that supports the surface portion, and a hollow structure portion (5) for allowing fluid to pass therethrough. A surface part (1) means the part which hits the light-receiving surface of sunlight among louver units. The surface portion (1) may be manufactured separately from the louver main body (2), and may be fixed to the louver main body (2), but may be integrally formed with the louver main body (2) as shown in FIG. Good. Moreover, you may form a surface part (1) with a solar cell panel (7), as shown in FIG. As the solar battery panel (7), for example, a plurality of solar battery cells are arranged, and a commercially available one can be used.
上記ルーバー本体（２）は、底面部（１２）と側面部（１１）とを有する。底面部（１２）がほぼ矩形の場合、側面部（１１）は、底面部（１２）の長手方向の向かい合う面だけに形成してもよいが、ルーバーユニット内部の空間部（１３）を外部から隔離し、温度や湿度などの内部環境を維持する観点から空間部（１３）を閉じた空間とするように４面に設けることが好ましい。 The louver body (2) has a bottom surface portion (12) and a side surface portion (11). In the case where the bottom surface portion (12) is substantially rectangular, the side surface portion (11) may be formed only on the opposing surfaces in the longitudinal direction of the bottom surface portion (12), but the space portion (13) inside the louver unit is externally provided. From the viewpoint of isolating and maintaining the internal environment such as temperature and humidity, it is preferable to provide four spaces so that the space (13) is a closed space.
上記中空構造部（５）は、その内部に流体を通過させるための中空部分を有することを要する。流体は、本発明のルーバーユニットが受けた太陽光のうち、熱エネルギーとなってルーバーやその周辺の温度上昇をもたらす熱を奪うために使用する。該流体は、中空構造部（５）の内部を移動できる流動性を持つものであれば、気体、液体ならびに粉体、粒状体などの固体でもよいが、経済性および熱エネルギーの回収の容易さの面から空気又は液体が好ましく、液体を用いることがより好ましい。さらに、液体としては経済性の点、汎用性の点から水を用いることがより好ましい。 The said hollow structure part (5) needs to have the hollow part for allowing a fluid to pass through in the inside. The fluid is used to take away heat from the sunlight received by the louver unit of the present invention, which becomes thermal energy and causes a temperature rise in the louver and its surroundings. The fluid may be solid such as gas, liquid, powder, and granular material as long as it has fluidity that can move inside the hollow structure portion (5), but it is economical and easy to recover heat energy. From the surface, air or liquid is preferable, and liquid is more preferable. Furthermore, as the liquid, it is more preferable to use water from the viewpoint of economy and versatility.
該中空構造部（５）は、前記空間部（１３）内に表面部（１）の背面と密着した状態で又は隙間をもって設ける。「密着した状態」には、中空構造部（５）と表面部（１）の背面とが直接密着する場合のほか、図１に記載されるように、表面部（１）と中空構造部（５）の一面とが一体化した場合や、図３に示すように、中空構造部（５）と表面部（１）の背面とが、熱伝導媒体（２１）を介して密着している場合がある。表面部（１）が太陽電池パネル（７）である場合のように、表面部（１）と中空構造部（５）とが別部材である場合、熱伝導媒体を用いることにより、表面部（１）や中空構造部（５）が不陸であることによる悪影響を軽減できる。すなわち、表面部（１）や中空構造部（５）に存在するゆがみやわずかな凹凸により、表面部と中空構造部とを密着させたときに生じる空隙を埋めて、熱移動効率が低下することを防止できる。また、表面部と中空構造部とを接触させたときの応力を吸収する効果もある。
熱伝導媒体は、０．１Ｗ／ｍＫ以上の熱伝導率を有することが好ましく、１Ｗ／ｍＫ以上であることがより好ましい。材質としては特に限定はなく、グラファイトシート、シリコンゴムシートなどの市販のものを使用することができる。表面部（１）と中空構造部（５）とが一体成形された場合や、表面部（１）の背面と中空構造部（５）とが密着している場合、熱移動効率が高く特に好ましく採用される。
一方、表面部（１）の背面と中空構造部（５）との間に隙間がある場合、熱は、空気を介して又は表面部の背面からの熱放射および熱対流により中空構造部（５）に伝わる。隙間の間隔が大きいと熱の移動効率が低下するので、表面部（１）の背面と中空構造部（５）との隙間は２０ｍｍ以下であることが好ましく、１０ｍｍ以下であることがより好ましい。
なお、本発明において、表面部（１）の背面とは、受光面に対して反対側の面のことをいう。
The hollow structure portion (5) is provided in the space portion (13) in close contact with the back surface of the surface portion (1) or with a gap. In the “adhered state”, in addition to the case where the hollow structure portion (5) and the back surface of the surface portion (1) are in direct contact, as shown in FIG. 1, the surface portion (1) and the hollow structure portion ( 5) When one surface is integrated or, as shown in FIG. 3, the hollow structure portion (5) and the back surface of the surface portion (1) are in close contact with each other via the heat conducting medium (21). There is. When the surface portion (1) and the hollow structure portion (5) are separate members, as in the case where the surface portion (1) is a solar cell panel (7), the surface portion ( 1) and the adverse effects due to the hollow structure (5) being uneven. That is, the heat transfer efficiency is lowered by filling the void generated when the surface portion and the hollow structure portion are brought into close contact with each other by the distortion or slight unevenness existing in the surface portion (1) or the hollow structure portion (5). Can be prevented. Moreover, there is also an effect of absorbing stress when the surface portion and the hollow structure portion are brought into contact with each other.
The heat conduction medium preferably has a thermal conductivity of 0.1 W / mK or more, and more preferably 1 W / mK or more. There is no limitation in particular as a material, Commercially available things, such as a graphite sheet and a silicon rubber sheet, can be used. When the surface portion (1) and the hollow structure portion (5) are integrally formed, or when the back surface of the surface portion (1) and the hollow structure portion (5) are in close contact, the heat transfer efficiency is particularly high. Adopted.
On the other hand, when there is a gap between the back surface of the surface portion (1) and the hollow structure portion (5), the heat is transferred to the hollow structure portion (5 by heat radiation or heat convection from the back surface of the surface portion. ) Since the heat transfer efficiency is reduced when the gap is large, the gap between the back surface of the surface portion (1) and the hollow structure portion (5) is preferably 20 mm or less, and more preferably 10 mm or less.
In the present invention, the back surface of the surface portion (1) refers to a surface on the opposite side to the light receiving surface.
本発明の建物用ルーバーユニットでは、上記中空構造部（５）を表面部（１）の背面に長手方向に設ける。図４では、太陽電池パネルの背面の２箇所に、中空構造部（５）が長手方向に平行に設けられている。一方の端部（例えば、右端）から導入された流体は、中空構造部（５）の内壁から熱を奪いながらもう一方の端部（例えば、左端）に達する。
このような構造により、本発明のルーバーユニットは、ルーバー本来の日射遮蔽による建物の冷房負荷削減および目隠しの機能に加えて、熱に変わった太陽エネルギーを有効利用できるとともに、ルーバー周辺の温度上昇を防ぎ、ヒートアイランド現象の緩和にも貢献する。特に、表面部（１）が太陽電池パネルである場合、太陽電池で電気に変換されず、熱に変わった太陽エネルギーを有効利用できるとともに、太陽電池の変換効率は温度が上昇すると低下するので、太陽電池パネルを冷却して、発電効率の低下を抑制することができる。また、太陽電池パネルの急激な温度変化を妨げ、太陽電池モジュールに与えるダメージを緩和し、太陽電池モジュールの安定化、長寿命化にも寄与できる。
In the building louver unit of the present invention, the hollow structure portion (5) is provided on the back surface of the surface portion (1) in the longitudinal direction. In FIG. 4, the hollow structure part (5) is provided in two places on the back surface of the solar cell panel in parallel to the longitudinal direction. The fluid introduced from one end (for example, the right end) reaches the other end (for example, the left end) while taking heat away from the inner wall of the hollow structure portion (5).
With such a structure, the louver unit of the present invention can effectively use solar energy changed to heat in addition to reducing the cooling load and blindfolding functions of the building due to the louver's original solar shading, and can also increase the temperature around the louver. Prevents and contributes to the mitigation of the heat island phenomenon. In particular, when the surface portion (1) is a solar cell panel, the solar cell is not converted to electricity, and solar energy converted to heat can be used effectively, and the conversion efficiency of the solar cell decreases as the temperature rises. The solar cell panel can be cooled to prevent a decrease in power generation efficiency. Moreover, the rapid temperature change of a solar cell panel is prevented, the damage given to a solar cell module is relieved, and it can contribute also to stabilization of a solar cell module and long life.
本発明のルーバーユニットにおいては、前記中空構造部（５）は、ルーバー本体（２）の側面部（１１）から空間部（１３）に向かって設けられた支持部（３）により固定されていることが好ましい。図３に示すように、中空構造部（５）と向かい合う両側面部（１１）とを架橋することで、ルーバー本体の変形を防止できる。さらに、中空構造部と表面部（１）の背面とを密着させることにより、表面部（１）の重量を中空構造部でも支えることになるため、本発明のルーバーユニットの構造安定性がより向上し好ましい。
また、図１、図３、図５に示すように、ルーバー本体（２）の底面部（１２）に、中空構造部（５）の重量を支える支持板（８）を長手方向に設けることにより、中空構造部が安定し、ルーバーユニット全体の剛性を高めることができる。
中空構造部（５）とルーバー本体の支持部（３）とは、溶接して固定してもよいが、断熱材や緩衝材などを介して固定してもよい。
更に、本発明の別の形態として中空構造部（５）は、押出成形などの一体成形により、ルーバー本体の両側面部（１１）から支持部（３）を介して一体化されていることが好適に採用される。中空構造部（５）とルーバー本体（２）とを一体化して押出成形する場合、上記支持板（８）を設けることにより、押出成形の際に中空構造部（５）とルーバー本体の支持部（３）のそり、うねり、変形を防止し、表面部（１）と中空構造部（５）とを所望の間隔に維持することを可能にするため特に好適に採用される。
In the louver unit of the present invention, the hollow structure portion (5) is fixed by a support portion (3) provided from the side surface portion (11) of the louver body (2) toward the space portion (13). It is preferable. As shown in FIG. 3, deformation of the louver body can be prevented by bridging the hollow structure portion (5) and the opposite side surface portions (11) facing each other. Furthermore, since the weight of the surface portion (1) is supported by the hollow structure portion by bringing the hollow structure portion and the back surface of the surface portion (1) into close contact with each other, the structural stability of the louver unit of the present invention is further improved. It is preferable.
Further, as shown in FIGS. 1, 3 and 5, a support plate (8) supporting the weight of the hollow structure portion (5) is provided in the longitudinal direction on the bottom surface portion (12) of the louver body (2). The hollow structure portion can be stabilized and the rigidity of the entire louver unit can be increased.
The hollow structure portion (5) and the support portion (3) of the louver main body may be fixed by welding, but may be fixed via a heat insulating material or a cushioning material.
Furthermore, as another embodiment of the present invention, the hollow structure portion (5) is preferably integrated from both side surface portions (11) of the louver body via the support portion (3) by integral molding such as extrusion molding. Adopted. When the hollow structure portion (5) and the louver body (2) are integrally formed by extrusion, by providing the support plate (8), the hollow structure portion (5) and the louver body support portion are formed during the extrusion. It is particularly preferably employed in order to prevent warping, undulation and deformation of (3) and to maintain the surface portion (1) and the hollow structure portion (5) at a desired distance.
本発明のルーバーユニットにおいて、中空構造部（５）は、表面部（１）の背面の１箇所でも複数個所に配置させてもよいが、流体を通過させるときの圧力の調整の容易さから２箇所以上が好ましい。一方、製造の容易さや表面部（１）が太陽電池パネルの場合、太陽電池の付属設備の設置場所を確保するため配置箇所は少ない方が好ましい。上記の点で２箇所であることが好ましく、図１、図３、図５にあるように、長手方向に２箇所平行に並べて配置することが好ましい。
上記中空構造部（５）は、図１に示すように表面部（１）やルーバー本体（２）と一体化し、一体成形してもよい。また、図３に示すように複数の中空構造部を一体化し、これを支持部（３）によってルーバー本体に固定される構造であってもよい。別の態様として、複数の中空構造部（５）どうしを、梁板（不図示）を介して固定し、この両側面を支持部（３）によってルーバー本体に固定される構造であってもよい。
In the louver unit of the present invention, the hollow structure portion (5) may be arranged at one place or a plurality of places on the back surface of the surface portion (1). More than the place is preferable. On the other hand, when the ease of manufacture and the surface portion (1) are solar cell panels, it is preferable that the number of arrangement locations is small in order to secure the installation location of the solar cell accessory equipment. In view of the above, it is preferable that there are two places, and as shown in FIGS. 1, 3, and 5, it is preferable to arrange two places in parallel in the longitudinal direction.
The hollow structure portion (5) may be integrated with the surface portion (1) and the louver body (2) as shown in FIG. Moreover, as shown in FIG. 3, the structure which integrates a some hollow structure part and fixes this to a louver main body by a support part (3) may be sufficient. As another aspect, a structure may be adopted in which a plurality of hollow structure portions (5) are fixed to each other via a beam plate (not shown), and both side surfaces thereof are fixed to the louver body by support portions (3). .

It is preferable that L / D is 2 or more and the long side faces the back surface of the surface portion (1). Thus, the contact area between the surface portion and the hollow structure portion is such that the hollow structure portion main body (31) is flat and the portion having this large area is in close contact with or opposed to the back surface of the surface portion (1). In addition, the contact area between the hollow structure portion and the fluid can be increased, and the heat energy can be efficiently absorbed by the fluid flowing inside the main body of the hollow structure portion.
As an example of a mode in which the cross section of the hollow structure body (31) used in the louver unit of the present invention is rectangular, the long side length L is 80 mm, the short side length D is 25 mm, A road cross-sectional area of 1,000 mm 2 can be mentioned. From the viewpoint of efficiency of heat transfer to the fluid, L / D is preferably 3 or more, and more preferably 5 or more.
In addition, a hollow structure part main body (31) means the frame | skeleton part except a processus | protrusion etc. when it has the processus | protrusion mentioned later here. FIG. 6 shows the main body (31) of the hollow structure portion (5) by hatching.
また、熱エネルギーの吸収効率の面から、上記表面部（１）の受光面の投影面積をＡ１、中空構造部本体（３１）の上記受光面への総投影面積（例として図２、図４にハッチングで示す）をＡ２としたときに、Ａ２／Ａ１が、０．３以上となることが好ましく、０．５以上となることにより熱吸収効率が高くなりより好ましい。なお、本発明において、表面部（１）の受光面の投影面積Ａ１とは、表面部を太陽方向に向けたときの面の面積をいい、図２や図４では、外側の実線で囲まれた矩形部分が相当する。
表面部（１）と中空構造部（５）とが一体化していない場合には、表面部（１）の背面に対峙する側の中空構造部（５）の面が、平坦面であることにより、表面部（１）の背面からの熱移動効率が高くなり好ましい。
Further, in terms of thermal energy absorption efficiency, the projected area of the light receiving surface of the surface portion (1) is A1, and the total projected area of the hollow structure portion main body (31) on the light receiving surface (for example, FIGS. 2 and 4). A2 / A1 is preferably 0.3 or more, and more preferably 0.5 or more, and the heat absorption efficiency is higher. In the present invention, the projected area A1 of the light receiving surface of the surface portion (1) refers to the area of the surface when the surface portion is directed in the solar direction, and is surrounded by an outer solid line in FIGS. The rectangular part corresponds.
When the surface portion (1) and the hollow structure portion (5) are not integrated, the surface of the hollow structure portion (5) facing the back surface of the surface portion (1) is a flat surface. The heat transfer efficiency from the back surface of the surface portion (1) is preferably increased.
流体への熱移動効率の点から、上記中空構造部（５）の材質は、熱伝導率の高いものが好ましく、常温での熱伝導率が１００Ｗ／ｍＫ以上であるものを使用することが好ましい。このような素材の例としては、アルミニウム、銅などを挙げることができる。特に、アルミニウムは、加工性に優れ、さらに軽量である点で優れている。 From the viewpoint of the efficiency of heat transfer to the fluid, the material of the hollow structure portion (5) preferably has a high thermal conductivity, and preferably has a thermal conductivity of 100 W / mK or more at room temperature. . Examples of such materials include aluminum and copper. In particular, aluminum is excellent in terms of excellent workability and light weight.
中空構造部（５）は、図９のように、内壁が内側に向かう突起を有してもよい。突起により流体との接触面積が増加し、流体への熱移動効率が向上する。また、図８のように、外壁が外側に向かう突起を有することにより、空間部（１３）の熱をより効率的に流体に伝えることができ、好ましい。このほか、中空構造部の別の態様の例として、図６、図７に示す態様を挙げることができる。 The hollow structure portion (5) may have a protrusion whose inner wall faces inward as shown in FIG. The contact area with the fluid is increased by the protrusion, and the efficiency of heat transfer to the fluid is improved. In addition, as shown in FIG. 8, it is preferable that the outer wall has a protrusion directed outward, so that the heat of the space (13) can be more efficiently transmitted to the fluid. In addition, examples of another aspect of the hollow structure portion include the aspects shown in FIGS. 6 and 7.
