Description

本発明は給湯機能付太陽光発電外壁パネルに関する。   The present invention relates to a photovoltaic power generation outer wall panel with a hot water supply function.

地下資源の枯渇や地球温暖化を防止するため、発電用の燃料が不要であり、かつ、発電時における二酸化炭素を排出しない発電装置の提供が強く望まれている。このような発電装置としてはいわゆる自然エネルギを用いた発電方法があり、具体的には太陽光発電装置、風力発電装置、マイクロ水力発電装置等が知られている。これら自然エネルギによる発電装置のうち、近年では太陽光発電装置が広く流通している。   In order to prevent depletion of underground resources and global warming, it is strongly desired to provide a power generation apparatus that does not require fuel for power generation and that does not emit carbon dioxide during power generation. As such a power generation device, there is a power generation method using so-called natural energy, and specifically, a solar power generation device, a wind power generation device, a micro hydropower generation device, and the like are known. Among these power generators using natural energy, solar power generators have been widely distributed in recent years.

このような太陽光発電装置に関する先行技術としては、特許文献1に開示されている構成が知られている。

特許文献1にかかる太陽光発電−集熱ハイブリッドパネルは構成が複雑であるため、パネル製造コストが高騰し、普及の足かせになるといった課題がある。また、パネル構造が複雑であるが故に、故障発生リスクが高いといった課題もある。さらには、熱交換を行う部分の構造が複雑であるため日照時間が短い冬場等における温水の生成功率が低くなるという課題もある。   Since the configuration of the photovoltaic power generation-heat collection hybrid panel according to Patent Document 1 is complicated, there is a problem that the panel manufacturing cost increases and becomes a drag on the spread. In addition, since the panel structure is complicated, there is a problem that the risk of failure occurrence is high. Furthermore, since the structure of the part which performs heat exchange is complicated, there also exists a subject that the success rate of warm water in winter etc. with a short sunshine time becomes low.

そこで本発明は、簡易な構造により、提供コストが安価で、かつ、故障発生リスクを低減させ、さらには、日照時間が短い冬場であっても十分な温水が供給可能な給湯機能付太陽光発電外壁パネルの提供を主たる目的としている。   Therefore, the present invention provides a solar power generation with a hot water supply function that can provide a sufficient amount of hot water even in winter when the provision cost is low, the risk of failure occurrence is reduced, and the sunshine time is short. The main purpose is to provide exterior wall panels.

Can do. Such a structure is particularly advantageous in cold regions.

また、前記ケースの外表面には、前記ケースどうしを連結させるための連結具が配設されていることが好ましく、前記ケースどうしを連結させた際に、一方の前記ケースに配設された前記連結具と、他方の前記ケースに配設された前記連結具とが厚さ方向に重なり合う高さ位置に配設されていることがさらに好ましい。   Moreover, it is preferable that a connector for connecting the cases is disposed on the outer surface of the case, and when the cases are connected, the one disposed in one of the cases More preferably, the connector and the connector disposed in the other case are disposed at a height position overlapping in the thickness direction.

これらにより、隣接する給湯機能付太陽光発電外壁パネルどうしの連結を容易に行うことができる。   By these, the adjacent solar power generation outer wall panel with a hot water supply function can be easily connected.

(第1実施形態)
以下、本発明にかかる給湯機能付太陽光発電外壁パネルの実施形態について図面に基づいて説明する。
図1〜図4に示すように、本実施形態にかかる給湯機能付太陽光発電外壁パネル100は、底板12と、底板12の外周縁位置から起立する側壁14とを有し、底板12および側壁14の内表面にそれぞれ反射膜15が形成されたケース10と、ケース10の開口部16を閉塞する配置でケース10に配設された太陽光発電パネル30と、側壁14を高さ方向に二分する仕切板18と、底板12と仕切板18との間に配設された吸熱用水供給パイプ20と、を有している。
(First embodiment)
Hereinafter, an embodiment of a solar power generation outer wall panel with a hot water supply function according to the present invention will be described based on the drawings.
As shown in FIGS. 1 to 4, the photovoltaic power generation outer wall panel 100 with a hot water supply function according to the present embodiment includes a bottom plate 12 and a side wall 14 that rises from an outer peripheral edge position of the bottom plate 12. The case 10 in which the reflective film 15 is formed on the inner surface of each of the 14, the solar power generation panel 30 disposed in the case 10 so as to close the opening 16 of the case 10, and the side wall 14 are divided into two in the height direction. And a heat absorbing water supply pipe 20 disposed between the bottom plate 12 and the partition plate 18.

本実施形態における底板12および側壁14の内表面には断熱用塗装面12A,14Aが形成されている。反射膜15は断熱用塗装面12A,14Aの表面に積層させた状態で配設されている。特に側壁14の内表面に配設される反射膜15については、仕切板18よりも下側となる範囲にのみ配設されていればよい。   Insulating surfaces 12A and 14A for heat insulation are formed on the inner surfaces of the bottom plate 12 and the side wall 14 in the present embodiment. The reflection film 15 is disposed in a state of being laminated on the surfaces of the heat insulating coating surfaces 12A and 14A. In particular, the reflective film 15 disposed on the inner surface of the side wall 14 may be disposed only in a range below the partition plate 18.

また、側壁14に配設された仕切板18により、ケース10の内部空間17は高さ方向に二分割されている。仕切板18の底板12側の面(仕切板18の下面)には第2反射膜18Aが配設されている。仕切板18には第2反射膜18Aと仕切板18を板厚方向に貫通する貫通孔19が所要間隔をあけた状態で複数穿設されている。また、仕切板18の太陽光発電パネル30側(仕切板18の上面)は黒色塗装が施されている。   Further, the internal space 17 of the case 10 is divided into two in the height direction by the partition plate 18 disposed on the side wall 14. A second reflective film 18A is disposed on the surface of the partition plate 18 on the bottom plate 12 side (the lower surface of the partition plate 18). A plurality of through-holes 19 penetrating the second reflective film 18A and the partition plate 18 in the thickness direction are formed in the partition plate 18 with a required interval therebetween. Moreover, the solar power generation panel 30 side (upper surface of the partition plate 18) of the partition plate 18 is black-coated.

本実施形態におけるケース10は、仕切板18により仕切られた下側内部空間17Aの内表面の全てが反射膜15と第2反射膜18Aとによって形成されていることになる。給湯機能付太陽光発電外壁パネル100に照射された太陽光は、太陽光発電パネル30の透明部分を通過した後、仕切板18の貫通孔19から下側内部空間17Aに進入することができ、下側内部空間17Aを昇温させることができる。先述のように、建物の居住空間側となる底板12および側壁14には断熱用塗装面12A,14Aが形成されているため、下側内部空間17Aに蓄積させた熱エネルギが居住空間に代表される建物の内部空間側に移動することは無い。   In the case 10 in this embodiment, the entire inner surface of the lower internal space 17A partitioned by the partition plate 18 is formed by the reflective film 15 and the second reflective film 18A. The sunlight irradiated to the photovoltaic power generation outer wall panel 100 with a hot water supply function can enter the lower inner space 17A from the through hole 19 of the partition plate 18 after passing through the transparent portion of the photovoltaic power generation panel 30. The lower inner space 17A can be heated. As described above, since the heat insulating coating surfaces 12A and 14A are formed on the bottom plate 12 and the side wall 14 on the living space side of the building, the thermal energy accumulated in the lower internal space 17A is represented by the living space. There is no movement to the interior space side of the building.

下側内部空間17Aには、給湯部の一部である下段の吸熱用水供給パイプ20Aと上段の吸熱用水供給パイプ20Bが配設されている。下段および上段の吸熱用水供給パイプ20A,20Bは、底板12の上面に配設されたスペーサ22A,22Bにより底板12の表面から離反させた状態で配設されている。下段および上段の吸熱用水供給パイプ20A,20Bはそれぞれケース10の長手方向に沿って往復させた配列で配設されている。   In the lower internal space 17A, a lower heat absorption water supply pipe 20A and an upper heat absorption water supply pipe 20B, which are part of the hot water supply section, are disposed. The lower and upper endothermic water supply pipes 20 </ b> A and 20 </ b> B are disposed in a state of being separated from the surface of the bottom plate 12 by spacers 22 </ b> A and 22 </ b> B disposed on the upper surface of the bottom plate 12. The lower and upper endothermic water supply pipes 20 </ b> A and 20 </ b> B are arranged in an array reciprocated along the longitudinal direction of the case 10.

このように下段および上段の吸熱用水供給パイプ20A,20Bは、給湯機能付太陽光発電外壁パネル100の外表面に面しない閉塞空間である下側内部空間17Aに配設されているが、仕切板18に穿設された貫通孔19を通過した太陽光により下側内部空間17Aにも太陽光を照射させることができ、下段および上段の吸熱用水供給パイプ20A,20B内の水を加熱することができる。   Thus, the lower and upper heat absorption water supply pipes 20A and 20B are disposed in the lower inner space 17A, which is a closed space that does not face the outer surface of the solar power generation outer wall panel 100 with a hot water supply function. The lower inner space 17A can be irradiated with sunlight by the sunlight that has passed through the through-hole 19 formed in 18 and the water in the lower and upper endothermic water supply pipes 20A and 20B can be heated. it can.

本実施形態においては、上段の吸熱用水供給パイプ20Bのケース10の長手方向に沿って延設された部分の平面位置と、下段の吸熱用水供給パイプ20Aのケース10の長手方向に沿って延設された部分の平面位置とは交互配置になるように配設されている。このような配置を採用することで、上段の吸熱用水供給パイプ20Bにより下段の吸熱用水供給パイプ20Aが陰に隠れてしまうことを防止し、太陽光が下段および上段の吸熱用水供給パイプ20A,20Bを直接照射することによる水の加熱を可能にしている。   In the present embodiment, the planar position of the portion of the upper-stage endothermic water supply pipe 20B extending along the longitudinal direction of the case 10 and the lower-stage endothermic water supply pipe 20A extending along the longitudinal direction of the case 10 are provided. They are arranged so as to be alternately arranged with the planar positions of the portions. By adopting such an arrangement, it is possible to prevent the lower endothermic water supply pipe 20A from being hidden behind the upper endothermic water supply pipe 20B, and sunlight is applied to the lower and upper endothermic water supply pipes 20A, 20B. The water can be heated by direct irradiation.

下段および上段の吸熱用水供給パイプ20A,20Bは、下段および上段の吸熱用水供給パイプ20A,20Bと共に給湯部を構成する水供給部と貯湯タンク(いずれも図示せず)に接続可能にすべく、始端部24(水供給部側(いわゆる上流側)に接続される端部)と終端部26(貯湯タンク側(いわゆる下流側)に接続される端部)がケース10の外表面に開口(露出)させた状態になっている。下段および上段の吸熱用水供給パイプ20A,20Bの始端部24と終端部26とは、着脱可能に雄雌嵌合する一対のプラグ構造に形成することで、隣接配置した給湯機能付太陽光発電外壁パネル100どうしにおける下段および上段の吸熱用水供給パイプ20A,20Bの始端部24と終端部26とを連結することができる。   The lower and upper endothermic water supply pipes 20A and 20B are connectable to a water supply unit and a hot water storage tank (both not shown) constituting a hot water supply unit together with the lower and upper endothermic water supply pipes 20A and 20B. The start end 24 (the end connected to the water supply side (so-called upstream)) and the end 26 (the end connected to the hot water storage tank (so-called downstream)) are opened (exposed) on the outer surface of the case 10. ). The lower end and upper end heat absorption water supply pipes 20A and 20B have a start end portion 24 and a terminal end portion 26 that are formed in a pair of plug structures that are detachably fitted into a male and female, so The start end portion 24 and the end end portion 26 of the lower and upper endothermic water supply pipes 20A and 20B in the panels 100 can be connected.

The solar power generation outer wall panel 100 with a hot water supply function according to the present embodiment is employed as an outer wall material of a building, in which a connecting tool 40 for connecting adjacent solar power generation outer wall panels 100 with a hot water supply function is provided. In this case, a drain hole 50 is formed in the side wall 14 which is the lower position. The meandering line shape of the lower endothermic water supply pipe 20A and the meandering line shape of the upper endothermic water supply pipe 20B are arranged so as to be orthogonal to each other in the horizontal plane. The upper-stage endothermic water supply pipe 20B is arranged in a state of being directly superimposed on the lower-stage endothermic water supply pipe 20A.

連結具40は、ケース10の側壁14の外表面に配設されている。互いに対向する位置の側壁14において、連結具40の配設位置が高さ方向において連結具40の厚さ寸法dと等しい寸法だけずらした位置に配設している。このような連結具40の構成により連結対象となる給湯機能付太陽光発電外壁パネル100どうしを、連結具40を介して連結する際に連結具40を厚さ方向に密着させた状態で連結することができる。板厚方向に密着させた連結具40にボルトおよびナットに代表される公知の締結手段を用いて締結することで給湯機能付太陽光発電外壁パネル100どうしを連結することができる。   The connector 40 is disposed on the outer surface of the side wall 14 of the case 10. In the side wall 14 of the position which mutually opposes, the arrangement | positioning position of the connection tool 40 is arrange | positioned in the position shifted by the dimension equal to the thickness dimension d of the connection tool 40 in the height direction. When connecting the solar power generation outer wall panels 100 with a hot water supply function to be connected with each other via the connector 40, the connector 40 is connected in a state of being closely attached in the thickness direction. be able to.

Moreover, since the connection structure of the photovoltaic power generation outer wall panels 100 with a hot water supply function is very simple, even an operator who is not a so-called craftsman can perform the outer wall construction of a building. Here, the outer wall material does not necessarily need to be a wall member, and if it constitutes the outer surface of a building, it is included in the outer wall material (outer wall panel) in this specification.

以上に本実施形態に基づいて本発明にかかる給湯機能付太陽光発電外壁パネル100の説明をしてきたが、本発明にかかる給湯機能付太陽光発電外壁パネル100の技術的範囲は以上の実施形態に限定されるものではない。例えば、以上の実施形態においては、下側内部空間17Aに高さ位置を異にした下段の吸熱用水供給パイプ20Aと上段の吸熱用水供給パイプ20Bとを二段に配設した形態について説明しているが、上下の二段配置に限定されるものではなく、1段配置にしてもよいし、3段以上に配置することもできる。   The solar power generation outer wall panel 100 with a hot water supply function according to the present invention has been described above based on the present embodiment, but the technical scope of the solar power generation outer wall panel 100 with a hot water supply function according to the present invention is as described above. It is not limited to. For example, in the above embodiment, a description will be given of a form in which the lower endothermic water supply pipe 20A and the upper endothermic water supply pipe 20B having different height positions are arranged in two stages in the lower internal space 17A. However, it is not limited to the upper and lower two-stage arrangement, and may be arranged in a single stage or in three or more stages.

また、下段の吸熱用水供給パイプ20Aと上段の吸熱用水供給パイプ20Bとはそれぞれパイプの延長方向に沿った長尺体形状のスペーサ22A,22Bにより支持されているが、下段の吸熱用水供給パイプ20Aと上段の吸熱用水供給パイプ20Bとをスポット的に支持するブロック形状のスペーサ22A,22Bの形態を採用することもできる。   Further, the lower-stage endothermic water supply pipe 20A and the upper-stage endothermic water supply pipe 20B are supported by elongated body-shaped spacers 22A and 22B along the extending direction of the pipe, respectively, but the lower-stage endothermic water supply pipe 20A. It is also possible to adopt the form of block-shaped spacers 22A and 22B that spot-support the heat absorption water supply pipe 20B in the upper stage.

また、仕切板18の上面側は黒色塗装を施した形態について説明したが、仕切板18の上面を反射面に形成することもできる。この場合、いわゆる両面発電型の太陽光発電パネル30を採用すると共に太陽光発電パネル30の被覆材料(カバーガラス)に防眩処理をしておくことが好ましい。   Moreover, although the upper surface side of the partition plate 18 demonstrated the form which gave black coating, the upper surface of the partition plate 18 can also be formed in a reflective surface. In this case, it is preferable to employ a so-called double-sided power generation type solar power generation panel 30 and to apply an antiglare treatment to the covering material (cover glass) of the solar power generation panel 30.
