Description

本発明は、太陽エネルギーを利用して、発電と集熱の両方を行うことのできる太陽光発電集熱システムに関する。   The present invention relates to a solar power generation heat collection system capable of performing both power generation and heat collection using solar energy.

太陽エネルギーの利用方法として、一般に、太陽光を太陽電池を用いて電気に変換する場合と、太陽熱を利用する場合とがある。例えば、前者の場合には、住宅の屋根の上面に複数の太陽電池モジュールを設置し、この太陽電池モジュールの太陽電池によって発電した直流の電力をインバータで交流に変換することによって、照明や空調等の電力として利用する場合（特許文献１参照）がある。また、後者の場合には、屋根に太陽エネルギーを集熱する集熱部材で覆った熱伝導性の優れた金属板等を設置し、その下方又は上方に暖められた空気が流通する空気流通層を備え、空気流通層に居住空間に空気を循環させるダクト等の空気流通系が設けられ、集熱した太陽熱を直接暖房として利用する場合（特許文献２参照）がある。
特開２００１−８１９８１号公報 特開平１１−２２３３５４号公報 As a method of using solar energy, there are generally a case where sunlight is converted into electricity using a solar cell and a case where solar heat is used. For example, in the case of the former, by installing a plurality of solar cell modules on the upper surface of the roof of a house and converting direct current power generated by the solar cells of this solar cell module into alternating current by an inverter, lighting, air conditioning, etc. In some cases, it is used as electric power (see Patent Document 1). In the latter case, an air circulation layer in which a heated metal plate or the like covered with a heat collecting member for collecting solar energy is installed on the roof, and warmed air circulates below or above the roof. The air circulation system is provided with an air circulation system such as a duct that circulates air into the living space, and the collected solar heat is directly used as heating (see Patent Document 2).
JP 2001-81981 A JP-A-11-223354

しかしながら、上述の場合、電気としての利用（発電）又は熱としての利用（集熱）のいずれかであるため、太陽エネルギーの利用効率の向上が要求されている。
すなわち、例えば、上記特許文献１に記載されているように発電として利用した場合に得られた電気を、特許文献２に記載されているように熱として利用する場合には、太陽光から変換された電気を再び熱に変換する必要があるためエネルギー利用効率が悪いという問題がある。また、集熱と発電の両方を行うためには、それぞれ別個の装置を設ける必要があるため、設置面積の増大及びコスト高を招くという問題もある。 However, in the above-mentioned case, since it is either utilization as electricity (power generation) or utilization as heat (heat collection), improvement in utilization efficiency of solar energy is required.
That is, for example, when electricity obtained when used as power generation as described in Patent Document 1 is used as heat as described in Patent Document 2, it is converted from sunlight. There is a problem that the energy utilization efficiency is poor because it is necessary to convert the electricity again into heat. Further, in order to perform both heat collection and power generation, it is necessary to provide separate devices, which causes a problem of increasing the installation area and increasing the cost.

本発明は、上記事情に鑑みてなされたもので、設置面積が増大することなく、低コストで、発電及び集熱を行うことができ、太陽エネルギーの利用効率を向上することのできる太陽光発電集熱システムを提供することを目的としている。   The present invention has been made in view of the above circumstances, and solar power generation capable of generating power and collecting heat at low cost without increasing the installation area and improving the utilization efficiency of solar energy. It aims to provide a heat collection system.

前記透光性部材８は、前記屋根面４２に所定間隔に複数設けられた支持レール１０に支持されており、
前記透光性部材８と前記屋根面４２と前記支持レール１０とによって囲まれる部分が空気流通層Ｓ３とされ、
前記空気流通層Ｓ３は、前記屋根面４２と前記太陽光発電モジュール６との間に形成された第１の隙間Ｓ１と、前記太陽光発電モジュール６と前記透光性部材８との間に形成された第２の隙間Ｓ２とを有し、
前記太陽光発電モジュール６は、前記第１の隙間Ｓ１を介して前記屋根面４２と離間し、前記第２の隙間Ｓ２を介して前記透光性部材８と離間し、かつ、前記支持レール１０と離間し、
前記空気流通層Ｓ３は、前記屋根面４２の棟５側に形成されて屋根裏に通じる屋内開口部４２４に連通しており、
床下１１には、潜熱を利用して蓄熱する潜熱蓄熱材である蓄熱手段１２が、所定間隔に複数段設けられ、
前記屋根４の棟５側において、前記空気流通層Ｓ３には、前記蓄熱手段１２に連結する伝熱手段１３が接続され、
前記伝熱手段１３は、建物１を構成する壁パネル１４及び床パネル１５を貫通して床下１１にまで配されており、
前記伝熱手段１３及び前記蓄熱手段１２の周囲には断熱材１５１が設けられ、
前記断熱材１５１は、前記床パネル１５の下面から基礎の２内面に沿って防湿土間コンクリート２aの上面までの間に設けられていることを特徴とする。 In order to solve the above-described problem, the invention of claim 1 is configured such that, for example, as shown in FIGS. 2 to 5, a plurality of solar power generation modules 6 are disposed above the roof surface 42. Is provided so as to cover at least the upper part of the solar power generation module 6,
The translucent member 8 is supported by a plurality of support rails 10 provided at predetermined intervals on the roof surface 42,
A portion surrounded by the translucent member 8, the roof surface 42, and the support rail 10 is an air circulation layer S3,
The air circulation layer S <b> 3 is formed between the first gap S <b> 1 formed between the roof surface 42 and the solar power generation module 6, and between the solar power generation module 6 and the translucent member 8. have a second gap S2 that is,
The solar power generation module 6 is separated from the roof surface 42 through the first gap S1, is separated from the translucent member 8 through the second gap S2, and the support rail 10 is provided. And away from
The air circulation layer S3 is formed on the ridge 5 side of the roof surface 42 and communicates with an indoor opening 424 that leads to the attic.
Under the floor 11, a plurality of stages of heat storage means 12, which is a latent heat storage material that stores heat using latent heat, are provided at predetermined intervals.
On the ridge 5 side of the roof 4, a heat transfer means 13 connected to the heat storage means 12 is connected to the air circulation layer S <b> 3,
The heat transfer means 13 passes through the wall panel 14 and the floor panel 15 constituting the building 1 and is arranged up to the floor 11.
A heat insulating material 151 is provided around the heat transfer means 13 and the heat storage means 12,
The heat insulating material 151 is provided between the lower surface of the floor panel 15 and the upper surface of the moisture-proof soil concrete 2a along the two inner surfaces of the foundation.

請求項１の発明によれば、屋根面４２に配設された複数の太陽光発電モジュール６によって、太陽光を電気（電力）に変換することができ、建物１で消費する電力を賄うことができるため、電力の自給自足を行うことができる。
また、太陽光発電モジュール６の上方に透光性部材８が少なくとも太陽光発電モジュール６の上方を覆うようにして設けられ、透光性部材８と屋根面４２との間に空気流通層Ｓ３が形成され、さらに、空気流通層Ｓ３には床下１１の蓄熱手段１２に連結する伝熱手段１３が接続されているので、太陽熱が透光性部材８を透光して空気流通層Ｓ３内の空気に伝達されることによって、その空気が加熱されて、さらに伝熱手段１３を介して蓄熱手段１２で蓄熱される。その結果、蓄熱手段１２に蓄熱された熱を床暖房に利用できるとともに、暖房機器等に使用される電力を削減することが可能となる。
したがって、このように発電と集熱とを同時に行うことができるため、太陽エネルギーの利用効率の向上を図ることができる。
また、従来のように発電と集熱の両方を行うためにそれぞれ別個の装置を設ける必要もないので、その設置面積の増大を防ぐことができ、しかもコスト削減を図ることができる。
また、太陽光発電モジュール６はその表面が透光性を有するガラス等によって覆われていることから、空気流通層Ｓ３の空気は、直接屋根面４２で吸収させて集熱した場合に比して、熱が屋根面４２に吸収されずに集熱率が高くなる。 According to the invention of claim 1, sunlight can be converted into electricity (electric power) by the plurality of photovoltaic power generation modules 6 disposed on the roof surface 42, and power consumed in the building 1 can be covered. Because it can, it can be self-sufficient in electricity.
Moreover, the translucent member 8 is provided above the solar power generation module 6 so as to cover at least the upper side of the solar power generation module 6, and an air circulation layer S <b> 3 is provided between the translucent member 8 and the roof surface 42. Further, since the heat transfer means 13 connected to the heat storage means 12 under the floor 11 is connected to the air circulation layer S3, solar heat is transmitted through the translucent member 8 and the air in the air circulation layer S3. , The air is heated and further stored in the heat storage means 12 via the heat transfer means 13. As a result, the heat stored in the heat storage means 12 can be used for floor heating, and the electric power used for the heating device or the like can be reduced.
Therefore, since power generation and heat collection can be performed simultaneously in this way, the utilization efficiency of solar energy can be improved.
Further, since it is not necessary to provide separate devices for both power generation and heat collection as in the prior art, it is possible to prevent an increase in the installation area and to reduce costs.
Further, since the surface of the photovoltaic power generation module 6 is covered with translucent glass or the like, the air in the air circulation layer S3 is directly absorbed by the roof surface 42 to collect heat. The heat collecting rate is increased without the heat being absorbed by the roof surface 42.

また、複数の太陽光発電モジュール６は、屋根面４２の上方に設けられているので、太陽光発電モジュール６は直接屋根面４２に接することなく、屋根面４２と太陽光発電モジュール６との間（隙間Ｓ１）にも空気が流通することとなる。そのため、乱流が生じ易くなり、その結果、空気流通層Ｓ３の空気との熱伝達が促進されることとなり、蓄熱手段１２に熱を吸収させ易く、熱効率に優れる。 In addition , since the plurality of solar power generation modules 6 are provided above the roof surface 42, the solar power generation module 6 does not directly contact the roof surface 42, and is not between the roof surface 42 and the solar power generation module 6. Air also flows through (gap S1). Therefore, turbulent flow is likely to occur, and as a result, heat transfer with the air in the air circulation layer S3 is promoted, so that the heat storage means 12 can easily absorb heat and is excellent in thermal efficiency.

また、伝熱手段１３は、屋根４の棟５側において空気流通層Ｓ３に接続されているので、空気流通層Ｓ３内で加熱された空気を屋根４の棟５側からそのまま伝熱手段１３に伝達することができる。つまり、温度の高い空気は屋根４の棟５側に上昇し易いことから、伝熱手段１３を棟５側に設けた方が軒先側に設ける場合よりも集熱率が高くなるため好ましい。
さらに、蓄熱手段１２は潜熱蓄熱材であるので、蓄熱容量を比較的大きくすることができ、また、蓄熱温度が安定するので蓄熱効果を高めることができる。 Further , since the heat transfer means 13 is connected to the air circulation layer S3 on the ridge 5 side of the roof 4, the air heated in the air circulation layer S3 is directly transferred from the ridge 5 side of the roof 4 to the heat transfer means 13 as it is. Can communicate. That is, since high temperature air tends to rise to the ridge 5 side of the roof 4, it is preferable to provide the heat transfer means 13 on the ridge 5 side because the heat collection rate is higher than the case where it is provided on the eaves side.
Furthermore, since the heat storage means 12 is a latent heat storage material, the heat storage capacity can be made relatively large, and since the heat storage temperature is stabilized, the heat storage effect can be enhanced.

請求項２の発明は、例えば、図２に示すように、請求項１に記載の太陽光発電集熱システムにおいて、
前記透光性部材８は、前記屋根面４２に所定間隔に複数設けられた支持レール１０に支持されていることを特徴とする。 The invention of claim 2 is, for example, as shown in FIG. 2, in the solar power collection system of claim 1 ,
The translucent member 8 is supported by a plurality of support rails 10 provided on the roof surface 42 at a predetermined interval.

請求項２の発明によれば、透光性部材８は屋根面４２に所定間隔に複数設けられた支持レール１０に支持されているので、透光性部材８を屋根面４２に容易かつ確実に設置することができる。すなわち、例えば、屋根面４２に太陽光発電モジュール６のみが設けられた既存の太陽光発電集熱システムであっても、その屋根面４２に支持レール１０を設けて、支持レール１０に透光性部材８を支持させることによって、既存の太陽光発電集熱システムを利用して容易に本発明の太陽光発電集熱システムとすることができる。 According to the invention of claim 2 , since the translucent member 8 is supported by the support rail 10 provided on the roof surface 42 at a predetermined interval, the translucent member 8 can be easily and reliably attached to the roof surface 42. Can be installed. That is, for example, even in an existing solar power collection system in which only the solar power generation module 6 is provided on the roof surface 42, the support rail 10 is provided on the roof surface 42, and the support rail 10 is translucent. By supporting the member 8, the solar power generation heat collection system of the present invention can be easily obtained using an existing solar power generation heat collection system.

本発明に係る太陽光発電集熱システムによれば、屋根面に配設された複数の太陽光発電モジュールによって、太陽光を電気（電力）に変換することができ、建物で消費する電力を賄うことができる。
また、太陽熱が透光性部材を透光して空気流通層内の空気に伝達されることによって、その空気が加熱され、さらに伝熱手段を介して蓄熱手段で蓄熱される。その結果、蓄熱された熱を床暖房に利用できるとともに電力を削減することができる。
したがって、このように発電と集熱とを同時に行うことができるため、太陽エネルギーの利用効率の向上を図ることができる。また、発電と集熱の両方を行うことができるので、それぞれ別個の装置を設ける必要もなく、その設置面積の増大を防ぐことができ、しかもコスト削減を図ることができる。 According to the solar power generation heat collecting system according to the present invention, sunlight can be converted into electricity (electric power) by a plurality of solar power generation modules arranged on the roof surface to cover the power consumed in the building. be able to.
Further, solar heat is transmitted through the translucent member and transmitted to the air in the air circulation layer, whereby the air is heated and further stored by the heat storage means via the heat transfer means. As a result, the stored heat can be used for floor heating and power can be reduced.
Therefore, since power generation and heat collection can be performed simultaneously in this way, the utilization efficiency of solar energy can be improved. In addition, since both power generation and heat collection can be performed, it is not necessary to provide separate devices for each, and an increase in the installation area can be prevented, and cost reduction can be achieved.

以下、本発明の実施の形態について図１〜図４を参照して説明する。

A plurality of photovoltaic modules 6 are inclined above the roof surface 42 (field board 41a) on one side of the roof surfaces 42 formed on both sides of the ridge 5 so as to be substantially parallel to the roof surface 42. (See FIGS. 2 and 3) are arranged vertically and horizontally at predetermined intervals. As a result, a gap S1 is formed between the roof surface 42 and the photovoltaic power generation module 6 so that air can flow as will be described later.

図２〜図４に示すように、太陽光発電モジュール６は、太陽光で発電する平板状の太陽電池を強化ガラスでラミネートし耐候性を持たせたものである。また、太陽光発電モジュール６の周縁には、該周縁を囲む四角枠状のフレーム７が設けられている。
フレーム７は、屋根４の傾斜方向に沿って左右に配置される一対の縦枠部７Ａと、これら縦枠部７Ａの上下端部を接続し、かつ、屋根４の桁方向に沿って配置される上枠部７Ｂ及び下枠部７Ｃとを備えている。これら縦枠部７Ａ、上枠部７Ｂ及び下枠部７Ｃは、長尺部材であって、その内周面に太陽光発電モジュール６が嵌め込まれる一対の突出片７１Ａ、７１Ｂ、７１Ｃが設けられている。また、縦枠部７Ａは、屋根面４２にビスＢ１により固定される固定片７２Ａを備えている。 As shown in FIGS. 2 to 4, the solar power generation module 6 is obtained by laminating a flat plate solar cell that generates power with sunlight with tempered glass to provide weather resistance. Further, a rectangular frame-like frame 7 surrounding the periphery is provided on the periphery of the solar power generation module 6.

また、各太陽光発電モジュール６の上方には、透光性部材８が少なくとも太陽光発電モジュール６の上方を覆うように設けられている。これによって、透光性部材８と屋根面４２との間、すなわち、太陽光発電モジュール６と透光性部材８との間の隙間Ｓ２及び前記隙間Ｓ１を有する空気流通層Ｓ３が形成されており、後述するように空気が相互に流通可能となっている。 The electricity output from the plurality of photovoltaic modules 6 is collected in a terminal box, which is a connector (not shown), and the electricity collected in the terminal box is converted from direct current to alternating current by an inverter. Sunlight is converted into electricity for use.
Further, a translucent member 8 is provided above each solar power generation module 6 so as to cover at least the top of the solar power generation module 6. As a result, a gap S2 between the translucent member 8 and the roof surface 42, that is, a gap S2 between the photovoltaic power generation module 6 and the translucent member 8, and an air circulation layer S3 having the gap S1 are formed. As will be described later, air can flow between each other.

透光性部材８としては、例えば透光性の良好なガラス等が挙げられ、平板状で、太陽光発電モジュール６を被覆するよう太陽光発電モジュール６よりも大きく形成されている。透光性部材８の周縁には、該周縁を囲む四角枠状のフレーム９が設けられている。   As the translucent member 8, for example, glass having good translucency can be used, and it is flat and formed larger than the solar power generation module 6 so as to cover the solar power generation module 6.

Each vertical frame portion 9A has a pair of protruding pieces 91A into which the same light-transmissive member 8 as the upper frame portion 9B and the lower frame portion 9C described above is fitted, and a fixed piece 92A fixed to the support rail 10. It has. The pair of vertical frame portions 9A arranged on the left and right sides has an opening K formed on the upper surface thereof, and a cover member 93A is attached to the opening K with a screw B2.

支持レール１０は、図２に示すように、内部が中空で縦枠部９Ａの固定片９２Ａを受けてビスＢ３で固定される縦枠受部１０１と、この縦枠受部１０１を支持し、屋根面４２上にビスＢ４で固定される縦枠支持部１０２とを備えている。縦枠受部１０１の長手方向に沿った両端には、透光性部材８及びカバー部材９３Ａとの間から万が一侵入してきた雨水等が屋根面４２上に落ちることを防ぐ止水部１０３が形成されている。   As shown in FIG. 2, the support rail 10 supports the vertical frame receiving portion 101 and the vertical frame receiving portion 101 which is hollow inside and receives the fixing piece 92A of the vertical frame portion 9A and is fixed by screws B3. A vertical frame support portion 102 fixed on the roof surface 42 with screws B4 is provided. At both ends along the longitudinal direction of the vertical frame receiving portion 101, water stop portions 103 that prevent rainwater or the like that has entered from between the translucent member 8 and the cover member 93A from falling on the roof surface 42 are formed. Has been.

したがって、上述のように構成された太陽光発電モジュール６、透光性部材８は以下のように屋根面４２に取り付けられている。
太陽光発電モジュール６は、その周縁が縦枠部７Ａ、上枠部７Ｂ及び下枠部７Ｃの一対の突出片７１Ａ、７１Ｂ、７１Ｃ内に嵌め込まれることによってフレーム７が取り付けられている。また、図２に示すように、屋根面４２上には防火対策を兼ねた防火用鋼板４２２が敷設されており、この防火用鋼板４２２上に調整材４２１を介して縦枠部７１Ａの固定片７２ＡがビスＢ１により固定されることによって、太陽光発電モジュール６が屋根面４２の上方に配置されている。ここで、屋根面４２と太陽光発電モジュール６との間には隙間Ｓ１が形成され、空気が流通可能となっている。 Therefore, the photovoltaic power generation module 6 and the translucent member 8 configured as described above are attached to the roof surface 42 as follows.
As for the solar power generation module 6, the frame 7 is attached by the periphery of the solar power generation module 6 being fitted into the pair of projecting pieces 71A, 71B, 71C of the vertical frame portion 7A, the upper frame portion 7B, and the lower frame portion 7C. In addition, as shown in FIG. 2, a fire-proof steel plate 422 that also serves as a fire-proof measure is laid on the roof surface 42, and a fixed piece of the vertical frame portion 71 </ b> A is placed on the fire-proof steel plate 422 via an adjustment material 421. The solar power generation module 6 is disposed above the roof surface 42 by fixing 72A with the screw B1. Here, a gap S <b> 1 is formed between the roof surface 42 and the solar power generation module 6 so that air can flow.

また、透光性部材８は、その周縁が縦枠部９Ａ、上枠部９Ｂ及び下枠部９Ｃの一対の突出片９１Ａ、９３Ｂ、９５Ｃ内に嵌め込まれることによってフレーム９が取り付けられている。また、図２に示すように、屋根面４２上には、支持レール１０がその縦枠支持部１０２がビスＢ４で固定されることによって取り付けられており、この支持レール１０２に縦枠部９Ａが支持されることによって透光性部材８が取り付けられている。
具体的には、上下方向に互いに隣接する透光性部材８は、図３及び図４に示すように、下方に配置される透光性部材８の上枠部９Ｂと上方に配置される透光性部材８の下枠部９Ｃとにおいて、下枠部９Ｃの鍔部９２Ｃが上枠部９Ｂの枠本体９１Ｂの上面に当接するとともに、上枠部９Ｂの当接片９２Ｂが下枠部９Ｃの枠本体９１Ｃの側面に当接することによって、互いに遊嵌している。
また、左右方向に互いに隣接する透光性部材８は、右側に配置される透光性部材８の縦枠部９Ａと左側に配置される透光性部材８の縦枠部９Ａとにおいて、支持レール１０の縦枠受部１０１に各縦枠部９Ａの固定片９２ＡがビスＢ３でそれぞれ固定されている。さらに、これら両縦枠部９Ａの上面に形成された開口Ｋには、ビスＢ２によりカバー部材９３Ａが取り付けられている。つまり、左右に隣接する透光性部材８どうしの間に、カバー部材９３Ａが配置されている。
このようにして透光性部材８が、少なくとも太陽光発電モジュール６の上方を覆うように配置され、これによって太陽光発電モジュール６と透光性部材８との間には隙間Ｓ２が形成され、空気が流通可能となっている。 Further, the translucent member 8 has the peripheral edge fitted into the pair of projecting pieces 91A, 93B, and 95C of the vertical frame portion 9A, the upper frame portion 9B, and the lower frame portion 9C, so that the frame 9 is attached. As shown in FIG. 2, the support rail 10 is mounted on the roof surface 42 by fixing the vertical frame support portion 102 with screws B4, and the vertical frame portion 9A is attached to the support rail 102. The translucent member 8 is attached by being supported.
Specifically, as shown in FIGS. 3 and 4, the translucent members 8 adjacent to each other in the vertical direction are disposed above the upper frame portion 9 </ b> B of the translucent member 8 disposed below. In the lower frame portion 9C of the optical member 8, the flange portion 92C of the lower frame portion 9C abuts on the upper surface of the frame main body 91B of the upper frame portion 9B, and the abutting piece 92B of the upper frame portion 9B is the lower frame portion 9C. By making contact with the side surface of the frame main body 91C, they are loosely fitted to each other.
Further, the translucent members 8 adjacent to each other in the left-right direction are supported by the vertical frame portion 9A of the translucent member 8 disposed on the right side and the vertical frame portion 9A of the translucent member 8 disposed on the left side. A fixing piece 92A of each vertical frame portion 9A is fixed to the vertical frame receiving portion 101 of the rail 10 with screws B3. Further, a cover member 93A is attached to the opening K formed on the upper surfaces of both the vertical frame portions 9A by screws B2. That is, the cover member 93 </ b> A is disposed between the translucent members 8 adjacent to the left and right.
Thus, the translucent member 8 is disposed so as to cover at least the upper part of the solar power generation module 6, thereby forming a gap S <b> 2 between the solar power generation module 6 and the translucent member 8, Air can be circulated.

また、上下に隣接する太陽光発電モジュール６どうしは所定間隔をあけて配置され、フレーム９と屋根面４２との間の空間により、隙間Ｓ１と隙間Ｓ２とが互いに連通しているので、空気が隙間Ｓ１と隙間Ｓ２との間で流通可能となっている。このように、透光性部材８と屋根面４２との間に、隙間Ｓ１と隙間Ｓ２とを有する空気流通層Ｓ３が形成されている。   Further, the photovoltaic power generation modules 6 adjacent to each other are arranged at a predetermined interval, and the space between the frame 9 and the roof surface 42 allows the gap S1 and the gap S2 to communicate with each other. Distribution is possible between the gap S1 and the gap S2. Thus, the air circulation layer S3 having the gap S1 and the gap S2 is formed between the translucent member 8 and the roof surface 42.

さらに、空気流通層Ｓ３は、透光性部材８の軒先側に取り付けられた面戸４６の隙間４２３と、屋根面４２の棟５側に形成されて屋根裏に通じる屋内開口部４２４とに連通している。また、屋内開口部４２４には、建物１内に配されて後述する床下１１に配置された蓄熱手段１２（図４参照）に連通する伝熱手段１３が接続されている。
ここで、伝熱手段１３を屋根面４２の棟５側に形成された屋内開口部４２４に接続したのは、空気流通層Ｓ３内で加熱された空気を屋根４の棟５側からそのまま伝熱手段１３に伝達することができるためである。つまり、温度の高い空気は屋根４の棟５側に上昇し易いことから、伝熱手段１３を棟５側に設けた方が軒先側に設ける場合よりも集熱率が高くなるため好ましい。 Further, the air circulation layer S3 communicates with a gap 423 of the face door 46 attached to the eaves side of the translucent member 8 and an indoor opening 424 formed on the ridge 5 side of the roof surface 42 and leading to the attic. ing. The indoor opening 424 is connected to a heat transfer means 13 which is arranged in the building 1 and communicates with a heat storage means 12 (see FIG. 4) arranged in the floor 11 described later.
Here, the heat transfer means 13 is connected to the indoor opening 424 formed on the ridge 5 side of the roof surface 42 because the air heated in the air circulation layer S3 is directly transferred from the ridge 5 side of the roof 4. This is because it can be transmitted to the means 13. That is, since high temperature air tends to rise to the ridge 5 side of the roof 4, it is preferable to provide the heat transfer means 13 on the ridge 5 side because the heat collection rate is higher than the case where it is provided on the eaves side.

伝熱手段１３としては、隙間Ｓ１や空気流通層Ｓ３で集熱された熱を伝達するものであれば良く、搬送ファンとダクトの組み合わせの他、例えば熱伝導率の大きなアルミニウムや銅等の金属製のパイプやダクト等が挙げられる。特に、パイプ内に揮発性の液体を封入した周知のヒートパイプが好適である。そして、この伝熱手段１３は、建物１を構成する後述する壁パネル１４及び床パネル１５を貫通して床下１１に配されている。   Any heat transfer means 13 may be used as long as it can transfer the heat collected in the gap S1 or the air circulation layer S3. In addition to a combination of a transport fan and a duct, for example, a metal such as aluminum or copper having a high thermal conductivity. Examples include pipes and ducts made of metal. In particular, a known heat pipe in which a volatile liquid is sealed in the pipe is suitable. The heat transfer means 13 is disposed under the floor 11 through a wall panel 14 and a floor panel 15 (to be described later) constituting the building 1.

蓄熱手段１２としては、蓄熱容量を比較的大きくすることができ、蓄熱効果を高める点で、例えば潜熱を利用して蓄熱する潜熱蓄熱材が好ましい。この潜熱蓄熱材とは、単体、共融混合物、又は凝固点降下物質の融解と凝固の潜熱によって蓄熱と放熱とが行われるものである。具体的には、硫酸ナトリウム１０水塩をポリプロピレン性の容器に充填したものや、パラフィンを特殊樹脂加工したアルミシートで封印したもの等を有効に用いることができる。
このような蓄熱手段１２は、図５に示すように、床下１１に所定間隔で複数段設けられており、これら蓄熱手段１２に伝熱手段１３である搬送ファン・ダクト又はパイプがそれぞれ熱授受可能に連結されている。 As the heat storage means 12, a latent heat storage material that stores heat using latent heat, for example, is preferable in that the heat storage capacity can be made relatively large and the heat storage effect is enhanced. The latent heat storage material is a material that stores and releases heat by melting and solidifying latent heat of a simple substance, a eutectic mixture, or a freezing point depressing substance. Specifically, it is possible to effectively use a material in which a sodium sulfate decahydrate is filled in a polypropylene container or a material in which paraffin is sealed with a special resin-processed aluminum sheet.
As shown in FIG. 5, such heat storage means 12 is provided in a plurality of stages at a predetermined interval in the floor 11, and a heat transfer means 13 can transfer heat to the heat storage means 12 by a transfer fan, duct, or pipe, respectively. It is connected to.

なお、図５に示す床下構造について説明すると、構築された基礎２の内側で地盤Ｇ上には防湿土間コンクリート２aが打設されており、基礎２の上端には台輪２１が敷き込まれ、台輪２１の上面のうちの内側半分に床パネル１５の端部、外側半分に半土台２２が設置されている。また、半土台２２及び床パネル１５の端部の上面に壁パネル１４が設置されている。台輪２１と半土台２２及び床パネル１５との間には気密性を確保するためのコーキング材２３が設けられている。   The underfloor structure shown in FIG. 5 will be described. A moisture-proof soil concrete 2a is placed on the ground G inside the constructed foundation 2, and a pedestal 21 is laid on the upper end of the foundation 2. An end portion of the floor panel 15 is installed on the inner half of the upper surface of the base 21 and a semi-base 22 is installed on the outer half. A wall panel 14 is installed on the upper surfaces of the end portions of the semi-base 22 and the floor panel 15. A caulking material 23 for ensuring airtightness is provided between the base 21 and the semi-base 22 and the floor panel 15.

壁パネル１４は、框材を矩形枠状に組み立てるとともに、この矩形枠の内部に補強用の桟材を縦横に組み付けて枠体１４aを構成し、この枠体１４a内に軟質断熱材１４bが充填され、枠体１４aの両面に合板等の面材１４cが設けられてなる。軟質断熱材１４bとしては、例えば、グラスウールやロックウール等が挙げられる。   The wall panel 14 assembles the frame material into a rectangular frame shape and assembles reinforcing bars in the rectangular frame vertically and horizontally to form a frame body 14a. The frame body 14a is filled with a soft heat insulating material 14b. Then, a face material 14c such as a plywood is provided on both surfaces of the frame body 14a. Examples of the soft heat insulating material 14b include glass wool and rock wool.

床パネル１５は、框材を矩形枠状に組み立てるとともに、この矩形枠の内部に補強用の桟材を縦横に組み付けて枠体１５aを構成し、この枠体１５aの片面に合板等の面材１５bが設けられてなる。また、床パネル１５内の外側端部と、床パネル１５の下面から基礎２の内面に沿って防湿土間コンクリート２aの上面までの間に断熱材１５１が設けられている。
防湿土間コンクリート２aの上方には、上述の蓄熱手段１２が複数段配置されており、これら蓄熱手段１２に、壁パネル１４内及び床パネル１５内に配された前記伝熱手段１３が連結されている。
したがって、伝熱手段１３を介して蓄熱手段１２に蓄熱された熱が放熱することにより、上述の各断熱材１５１によって断熱されて床暖房とすることができる。ここで、各断熱材１５１は、伝熱手段１３及び蓄熱手段１２以外への熱の拡散を防ぐことができ、暖房効果をより一層高めている。 The floor panel 15 assembles the frame material into a rectangular frame shape, and vertically and horizontally assembles reinforcing bars inside the rectangular frame to form a frame body 15a. A surface material such as plywood is formed on one side of the frame body 15a. 15b is provided. Further, a heat insulating material 151 is provided between the outer end portion in the floor panel 15 and the lower surface of the floor panel 15 along the inner surface of the foundation 2 to the upper surface of the moisture-proof soil concrete 2a.
Above the moisture-proof soil concrete 2a, the heat storage means 12 is arranged in a plurality of stages, and the heat transfer means 13 disposed in the wall panel 14 and the floor panel 15 is connected to the heat storage means 12. Yes.
Therefore, when the heat stored in the heat storage means 12 is radiated through the heat transfer means 13, the heat is insulated by each of the heat insulating materials 151 described above, and floor heating can be performed. Here, each heat insulating material 151 can prevent the diffusion of heat to other than the heat transfer means 13 and the heat storage means 12, further enhancing the heating effect.

なお、図３に示す屋根４の軒先側先端には、結合桁４３を介して桶４４が設けられており、屋根面４２の軒先先端から桶４４まで水切り４５が設けられている。
また、屋根４の棟５側の上端側は、屋根面４２上に横部材５１が取り付けられており、横部材５１上に棟換気金物５２aや棟包み５２b等で構成された棟役物５２で覆われている。 In addition, the eaves side front-end | tip of the roof 4 shown in FIG. 3 is provided with the eaves 44 via the joint girder 43, and the draining 45 is provided from the eaves-end front of the roof surface 42 to the eaves 44.
In addition, the upper end side of the roof 4 on the side of the ridge 5 is provided with a horizontal member 51 on the roof surface 42, and a ridge member 52 constituted by a ridge ventilation hardware 52a, a ridge wrap 52b, etc. on the horizontal member 51. Covered.

以上、本発明の実施の形態の太陽光発電集熱システムによれば、屋根面４２に配設された複数の太陽光発電モジュール６によって、太陽光を電気（電力）に変換することができ、建物１で消費する電力を賄うことができる。
また、太陽光発電モジュール６の上方に、該上方を覆うようにして透光性部材８が設けられ、透光性部材８と屋根面４２との間に空気流通層Ｓ３が形成され、さらに、空気流通層Ｓ３には床下１１の蓄熱手段１２に連結する伝熱手段１３が接続されているので、太陽熱が透光性部材８を透光して空気流通層Ｓ３の空気に伝達されることによって、その空気が加熱され、さらに伝熱手段１３を介して蓄熱手段１２で蓄熱される。その結果、蓄熱手段１２に蓄熱された熱を床暖房に利用できるとともに、暖房機器等に使用される電力を削減することが可能となる。
しかも、屋根面４２と太陽光発電モジュール６との間にも隙間Ｓ１が形成されているので、この隙間Ｓ１にも空気が流通することとなる。そのため、乱流が生じ易くなることから、空気流通層Ｓ３の空気との熱伝達が促進されることとなり、蓄熱手段１２に熱を吸収させ易く、熱効率に優れる。
このように本発明の太陽光発電集熱システムでは、発電と集熱とを同時に行うことができるため、太陽エネルギーの利用効率の向上を図ることができる。また、発電と集熱の両方を行うために別個の装置を設ける必要もないので、その設置面積の増大を防ぐことができるとともにコスト削減を図ることができる。
さらに、太陽光発電モジュール６はその表面が透光性を有するガラスでラミネートされていることから、空気流通層Ｓ３の空気は、太陽光発電モジュール６が設けられておらず、直接屋根面４２で吸収させて集熱した場合に比して、太陽光発電モジュール６の表面で吸収させて集熱した場合の方が、熱が屋根面４２に吸収されずに集熱率が高くなる。 As described above, according to the solar power generation heat collecting system of the embodiment of the present invention, sunlight can be converted into electricity (electric power) by the plurality of solar power generation modules 6 disposed on the roof surface 42, The power consumed in the building 1 can be covered.
In addition, a translucent member 8 is provided above the photovoltaic power generation module 6 so as to cover the upper side, and an air circulation layer S3 is formed between the translucent member 8 and the roof surface 42. Since the heat transfer means 13 connected to the heat storage means 12 under the floor 11 is connected to the air circulation layer S3, solar heat is transmitted through the translucent member 8 and transmitted to the air in the air circulation layer S3. The air is heated and further stored in the heat storage means 12 via the heat transfer means 13. As a result, it is possible to use the heat stored in the heat storage means 12 for floor heating and to reduce the electric power used for the heating equipment and the like.
Moreover, since the gap S1 is also formed between the roof surface 42 and the photovoltaic power generation module 6, air flows through the gap S1. Therefore, since turbulent flow is likely to occur, heat transfer with the air in the air circulation layer S3 is promoted, the heat storage means 12 can easily absorb heat, and heat efficiency is excellent.
As described above, in the solar power generation heat collecting system of the present invention, since power generation and heat collection can be performed at the same time, the utilization efficiency of solar energy can be improved. Moreover, since it is not necessary to provide a separate device for performing both power generation and heat collection, it is possible to prevent an increase in the installation area and to reduce costs.
Further, since the surface of the photovoltaic module 6 is laminated with light-transmitting glass, the air in the air circulation layer S3 is not provided with the photovoltaic module 6, and directly on the roof surface 42. Compared with the case of collecting heat by absorbing, the case of collecting heat by absorbing on the surface of the solar power generation module 6 increases the heat collection rate without being absorbed by the roof surface 42.

また、透光性部材８は屋根面４２に所定間隔に複数設けられた支持レール１０に支持されているので、透光性部材８を屋根面４２に容易かつ確実に設置することができる。また、既存の太陽光発電集熱システムを利用して容易に本発明の太陽光発電集熱システムとすることができる。   In addition, since the translucent member 8 is supported by the support rails 10 provided on the roof surface 42 at a predetermined interval, the translucent member 8 can be easily and reliably installed on the roof surface 42. Moreover, it can be easily set as the solar power generation heat collection system of this invention using the existing solar power generation heat collection system.

なお、本発明は上記実施の形態に限定されるものではなく、その要旨を逸脱しない範囲で適宜変更可能なものとする。
例えば、太陽電池モジュール６のフレーム７、透光性部材８のフレーム９及び支持レール１０等の構造は適宜変更しても構わない。
また、上記建物１としては、壁パネル１４、床パネル１５を複数組み合わせたパネル工法による建物１を例に挙げたが、これに限らず、箱状に形成された建物ユニットを複数組み合わせたユニット式建物や、柱及び梁を建築現場で接合する在来工法からなる一般的な建物であっても構わない。 In addition, this invention is not limited to the said embodiment, It shall change suitably in the range which does not deviate from the summary.
For example, the structure of the frame 7 of the solar cell module 6, the frame 9 of the translucent member 8, the support rail 10, and the like may be appropriately changed.
Moreover, although the building 1 by the panel construction method which combined multiple wall panels 14 and floor panels 15 was mentioned as an example as the said building 1, it is not restricted to this, Unit type which combined multiple building units formed in the box shape The building may be a general building made of a conventional method of joining columns and beams at a construction site.
