Description

本発明は、太陽エネルギーを利用するものとして、太陽で温められる空気によって暖房等を行う空気式ソーラーシステムに関するものである。   The present invention relates to a pneumatic solar system that uses solar energy to perform heating or the like with air heated by the sun.

生活のレベルを低下させることなく、生活の高度化をはかりつつ、環境負荷を低減させる方法を生み出すために、風およびその他気象条件だけではなく、外部環境条件に柔軟に対応する住居および建物を建設して室内暖房、冷房、換気、除湿、および給湯のための太陽エネルギー利用を最適化することが求められる。   Build houses and buildings that flexibly respond to external environmental conditions as well as wind and other weather conditions in order to create ways to reduce environmental impacts while reducing the level of living and improving the sophistication of living. Thus, it is required to optimize the use of solar energy for room heating, cooling, ventilation, dehumidification, and hot water supply.

日本の伝統的住宅においても、太陽熱利用をはかる方法としては住宅の南部に大きな開口部を取って冬の日射を大量に取入れ、夏にはその一部を開け放って通風を図ることが行われることがあり、さらに、これを一歩進めて、居室の外側にサンルームを作り、これを温室としてここから居室へ温められた空気を取入れることも行われている。その場合、蓄熱されるのは空気だけであるが、例えばコンクリート外壁の外側にガラス等でカバーを施し、その間を室内への空気循環路とすれば、この外壁自体が蓄熱体として作用し安定した熱の供給が得られる。   Even in traditional Japanese houses, the method of using solar heat is to take a large opening in the southern part of the house and incorporate a large amount of solar radiation in the winter, and open a part of it in the summer for ventilation. In addition, there is also a process of taking this one step further, creating a solarium outside the room, and using this as a greenhouse to take in warm air from here. In that case, heat is stored only in the air, but if the outside of the concrete outer wall is covered with glass or the like and the space between them is used as an air circulation path to the room, the outer wall itself acts as a heat storage body and is stable. A supply of heat is obtained.

しかし、これらの方式はいずれも比較的南面した室内空間のコントロールにのみ限定されてしまい、北面した室内空間との間に大きな温度差が生じてしまうという欠点がある。   However, these methods are limited only to the control of the indoor space facing relatively south, and there is a drawback that a large temperature difference occurs between the indoor space facing north.

これを一歩進めて、居室の外側にサンルームを作り、これを温室としてここから居室へ温められた空気を取入れることも行われている。これを合理的に推進させ、方位に限定されず、太陽光により集熱した空気を効果的に利用できるソーラーシステムハウスの特許が下記特許文献に示すように存在する。
特許第３２７４８５８号公報 Taking this one step further, a sunroom is created outside the room, and this is used as a greenhouse to take in warm air from here. There is a patent of a solar system house that rationally promotes this and is not limited to the azimuth and can effectively use air collected by sunlight as shown in the following patent documents.
Japanese Patent No. 3274858

前記特許文献１のソーラーシステムハウスは、図１２にあるように、集熱面であるカラー鉄板の金属製屋根板１の直下に屋根勾配を有する空気流路２を形成し、この空気流路２の一方の端は軒先に空気取入口３として開口し、さらに空気流路２の他方の端は集熟ダクトとしての棟ダクト４に連通させる。屋根板１の一部はガラス２３で覆い、ガラス付き集熱面とする。   In the solar system house of Patent Document 1, as shown in FIG. 12, an air flow path 2 having a roof gradient is formed immediately below a metal roof plate 1 of a color iron plate that is a heat collecting surface. The other end of the air flow path 2 is communicated with a ridge duct 4 as a condensing duct. A part of the roof plate 1 is covered with glass 23 to form a heat collecting surface with glass.

内部に逆流防止兼流路切換えダンパー６、ファン７及び流路切換えダンパー８を設けたハンドリングボックス５を屋根裏空間である小屋裏２２に設置し、ハンドリングボックス５の流路切換えダンパー８の流出側の一方は排気ダクト９により屋外に開口する。   A handling box 5 provided with a backflow prevention / flow path switching damper 6, a fan 7 and a flow path switching damper 8 is installed in the shed 22, which is an attic space. One opens to the outside by an exhaust duct 9.

また、ハンドリングボックス５の逆流防止兼流路切換えダンパー６の流入側は、前記棟ダクト４に連通させる接続ダクトと室内２０からの循環ダクト１８とに選択的に接続し、流路切換えダンパー８の流出側の他の一方を立下りダクト１０の上端に連結する。   Further, the inflow side of the backflow prevention / flow path switching damper 6 of the handling box 5 is selectively connected to a connection duct communicating with the building duct 4 and a circulation duct 18 from the room 20, so that the flow path switching damper 8 The other one on the outflow side is connected to the upper end of the falling duct 10.

立下りダクト１０の下端は床下蓄熱体としての土間コンクリート１１と床パネル１２との間の空気流通空間１３に開口した。さらに、該空気流通空間１３から室内への床吹出口１４を設けた。   The lower end of the falling duct 10 opened to the air circulation space 13 between the soil concrete 11 as the underfloor heat storage body and the floor panel 12. Furthermore, a floor outlet 14 from the air circulation space 13 to the room was provided.

ハンドリングボックス５の内部またはハンドリングボックス５と棟ダクト４との間にお湯とりコイル１５を設け、このお湯とりコイル１５は循環配管１６で貯湯槽１７に連結する。図示は省略するが貯湯槽１７は循環ポンプと有し、また、必要に応じて追焚き用の給湯ボイラーを途中へ設けて、風呂や洗面所、台所へとつながる給湯配管をこの貯湯槽１７に接続する。   A hot water take-off coil 15 is provided inside the handling box 5 or between the handling box 5 and the building duct 4, and the hot water take-off coil 15 is connected to a hot water tank 17 through a circulation pipe 16. Although not shown, the hot water storage tank 17 has a circulation pump, and if necessary, a hot water supply boiler for reheating is provided in the middle of the hot water supply pipe connected to the bath, the washroom, and the kitchen. Connecting.

このようにして、暖房が必要な冬の昼間は、軒先の空気取入口３から入った冷たい空気は、屋根板１に降り注ぐ太陽の熱によって徐々に暖められる。この温められた空気は屋根勾配に沿って上昇する。そして、この加熱空気は棟ダクト４に集められてからファン７によりハンドリングボックス５に入り、ハンドリングボックス５から立下りダクト１０内へ流下し、床下に送られる。   In this way, during the winter daytime when heating is required, the cold air that has entered from the air intake 3 at the eaves is gradually warmed by the heat of the sun that falls on the roof plate 1. This warmed air rises along the roof slope. The heated air is collected in the ridge duct 4 and then enters the handling box 5 by the fan 7, flows down from the handling box 5 into the falling duct 10, and is sent under the floor.

空気は床下に広がり、蓄熱土間コンクリート１１に熱を奪われ（蓄えさせ）ながら、床吹出口１４から温風として室内２０へと流れ出る。夕方、外気温が下がり始める頃から、昼間、蓄熱土間コンクリート１１に蓄えられた熱が放熱を始め、床を温める。   The air spreads under the floor and flows out into the room 20 as warm air from the floor outlet 14 while the heat storage soil concrete 11 is deprived (stored). In the evening, when the outside air temperature starts to drop, the heat stored in the thermal storage soil concrete 11 starts to dissipate and warms the floor in the daytime.

つまり、太陽エネルギーは昼間に偏在しており、それを集熱してそのまま室内に放熱した場合は、逆に室温が高くなり過ぎてしまうのである。それを避けるために、昼間に集熱した熱を、床下の土間コンクリートに蓄熱、集熱部位と蓄熱部位を分ける。   In other words, solar energy is unevenly distributed in the daytime, and if it is collected and radiated indoors as it is, the room temperature becomes too high. In order to avoid this, heat collected during the daytime is stored in soil concrete under the floor, and the heat collection part and heat storage part are separated.

コンクリートは、熱容量（熱を蓄える量）や熱伝導率（熱の伝わりやすさ）が大きい。コンクリートが持つこの性質は、昼間に蓄熱し夜間に放熱するという、一日のサイクルに適応しており、夜になって外気温が低下するとともに、昼間床下に蓄えられた熱が放熱し始め、室内の暖房用として使われる。   Concrete has a large heat capacity (amount of heat stored) and thermal conductivity (easy heat transfer). This property of concrete is adapted to the daily cycle of storing heat in the daytime and radiating at night, and at night, the outside temperature decreases, and the heat stored under the floor in the day begins to radiate, Used for indoor heating.

夏の昼間は暖房の不要な期間であり、太陽熱で温められた空気は、昼間、貯湯槽１７内の水を温めることに利用される。すなわち、流路切換えダンパー８の流出側を排気ダクト９に接続し、お湯とりコイル１５で湯を作るだけで、前記排気ダクト９から戸外へ捨てられる。   Summer daytime is an unnecessary period of heating, and air heated by solar heat is used to warm water in the hot water tank 17 during the daytime. That is, the outflow side of the flow path switching damper 8 is connected to the exhaust duct 9 and hot water is made by the hot water take-off coil 15 and is discarded from the exhaust duct 9 to the outdoors.

お湯とりコイル１５では、ここに循環配管１６を介して貯湯槽１７から送り込まれる熱媒が加熱され、湯として貯湯槽１７へ蓄えられ、さらにここから必要に応じて追焚き用の給湯ボイラーで再加熱されて給湯配管から各所へ給湯される。   In the hot water take-up coil 15, the heat medium sent from the hot water storage tank 17 through the circulation pipe 16 is heated here and stored as hot water in the hot water storage tank 17, and further reheated by a hot water supply boiler as needed. It is heated and hot water is supplied to various places from the hot water supply piping.

快晴の日の雲のない夏の夜は、ファン７を駆動して軒先の空気取入口３から外気を空気流路２に取り込み、放射冷却現象（放射冷却で屋根全体が冷える）を利用して、涼しい外気を室内に取り込む。冷房のようには冷えないが、寝苦しくない夏の夜を演出できる。   On a clear summer day with no clouds, the fan 7 is driven to take outside air from the air intake 3 at the eaves into the air flow path 2 and use a radiative cooling phenomenon (the entire roof is cooled by radiant cooling). Bring cool outdoor air into the room. You can produce a summer night that doesn't cool like air conditioning, but isn't hard to sleep.

この特許文献１では、屋根全体を集熱面とするもので、ガラス２３で覆い、温室空気越しの高温集熱を行う高温集熱面とそれ以外の低温集熱面とに分かれるものの、図１３に示すように、金属板瓦棒葺き（浮屋根工法）による。   In this patent document 1, the entire roof is used as a heat collecting surface, which is divided into a high temperature heat collecting surface which is covered with glass 23 and performs high temperature heat collection through the greenhouse air, and other low temperature collecting surfaces. As shown in Fig. 4, it is based on a metal plate roofing method (floating roof method).

通常のソーラーシステムハウスの場合、集熱部としての金属製屋根板１の直下に屋根勾配を有する空気流路２とヘッダーダクトとしての棟ダクト４との関係は、棟ダクト４の中央から接続して、それをファン７に送る。   In the case of a normal solar system house, the relationship between the air flow path 2 having a roof gradient immediately below the metal roof plate 1 as a heat collecting part and the ridge duct 4 as a header duct is connected from the center of the ridge duct 4. And send it to Fan 7.

しかし、新築ではなく、リフォーム（後付け）施工とする場合は、設置スペースがないことから、中央から接続することが難しく、棟ダクト４の端から接続する必要が生じる。   However, when it is not a new construction but a renovation (retrofitting) construction, since there is no installation space, it is difficult to connect from the center, and it is necessary to connect from the end of the ridge duct 4.

後付けタイプの集熱部２８を図１４に示すように複数を並列に並べ、これらをそれぞれ棟ダクト４に接続すると、棟ダクト４の送風側（送風側ファン７）に近いものほど、集熱部２８の通過風量が多く温度が低くなり、棟ダクト４の送風側に遠いものほど、集熱部２８の通過風量が多く温度が高くなり、アンバランスが生じてしまう。   As shown in FIG. 14, a plurality of retrofitted type heat collecting units 28 are arranged in parallel and are connected to the building duct 4, and the heat collecting unit 28 is closer to the blowing side (the blowing fan 7) of the building duct 4. The amount of air passing through 28 is large and the temperature is low, and the farther to the air blowing side of the ridge duct 4 is, the more air passing through the heat collecting section 28 is, and the temperature is high, resulting in an imbalance.

図中２９は集熱部２８の端部に形成する空気入口であるが、この部分で各集熱部２８に均等な風量を流し均等な集熱温度を得ようとすると、施工時において各列での空気入口２９の空気流量調整が必要で、手間が大変である。   In the figure, reference numeral 29 denotes an air inlet formed at the end of the heat collecting section 28. In this portion, if an equal amount of air is supplied to each heat collecting section 28 to obtain a uniform heat collecting temperature, each row is arranged at the time of construction. Therefore, it is necessary to adjust the air flow rate at the air inlet 29, which is troublesome.

また、風量調整をすると集熱部２８の開口面積を減らすことになり、その結果、空気入口２９の通過流速が速まり、振動や騒音の発生の元となる。   Further, when the air volume is adjusted, the opening area of the heat collecting section 28 is reduced. As a result, the passage flow velocity of the air inlet 29 is increased, which causes generation of vibration and noise.

本発明の目的は前記従来例の不都合を解消し、集熱部をリフォーム（後付け）することを前提に、集熱部を複数並列に並べ、これらを棟ダクトの端部から接続する場合でも、簡単に各集熱部の通過風量を均一化し、その結果、均一の集熱が得られる空気式ソーラーシステムを提供することにある。   The purpose of the present invention is to eliminate the inconvenience of the conventional example, and on the premise that the heat collecting part is reformed (retrofit), even when arranging the heat collecting parts in parallel and connecting them from the end of the ridge duct, It is an object of the present invention to provide a pneumatic solar system that can easily equalize the amount of air passing through each heat collecting section and as a result obtain uniform heat collection.

前記目的を達成するため請求項１記載の本発明は、集熱面を設け、この集熱面下を勾配を有する空気流路とした空気式集熱部を集熱ダクトとしての棟ダクトに連通させ、棟ダクトからの温風を送風ファンで建物内に取り込む空気式ソーラーシステムにおいて、前記上面を集熱面とした空気流通の集熱部は複数を並設して棟ダクトに接続し、また、集熱部の各空気入口には前記棟ダクトに並行して風量調整用の入口ダクトを設けて該入口ダクトにより共通させ、該入口ダクトの空気取入れ開口は下向きに開口したことを要旨とするものである。 In order to achieve the above object, the present invention according to claim 1 is characterized in that a heat collecting surface is provided, and an air type heat collecting portion having an air flow path having a gradient below the heat collecting surface communicates with a building duct as a heat collecting duct. In the pneumatic solar system that takes in the warm air from the building duct into the building with a blower fan, a plurality of air collecting heat collecting portions with the upper surface as the heat collecting surface are arranged in parallel and connected to the building duct. , each air inlet of the heat collector is common by the inlet duct provided with an inlet duct for air volume adjustment in parallel with the building duct, air intake opening of the inlet duct and summarized in that the downwardly open Is.

請求項１記載の本発明によれば、入口ダクト（チャンバー部）を設けて、取り入れ口の開口面積および配置で調整することで、風量調整を行うので、調整箇所が減り、また、集熱部の入口面積を減らさないので風速等の問題は生じない。   According to the first aspect of the present invention, since the air volume is adjusted by providing the inlet duct (chamber part) and adjusting the opening area and arrangement of the intake port, the number of adjustment points is reduced, and the heat collecting part The problem of wind speed does not occur because it does not reduce the entrance area.

請求項２記載の本発明は、入口ダクトの上面も集熱面とすることを要旨とするものである。   The gist of the present invention described in claim 2 is that the upper surface of the inlet duct is also a heat collecting surface.

請求項２記載の本発明によれば、入口ダクトの上面も集熱面とすることで、この部分にも集熱機能を持たせることができる。   According to the second aspect of the present invention, since the upper surface of the inlet duct is also a heat collecting surface, this portion can also have a heat collecting function.

以上述べたように本発明の空気式ソーラーシステムは、集熱部をリフォーム（後付け）することを前提に、集熱部を複数並列に並べ、これらを棟ダクトの端部から接続する場合でも、簡単に各集熱部の通過風量を均一化し、その結果、均一の集熱が得られるものである。   As described above, the pneumatic solar system of the present invention is based on the premise that the heat collecting part is reformed (retrofit), even when arranging the heat collecting parts in parallel and connecting them from the end of the ridge duct, The amount of air passing through each heat collecting section is easily made uniform, and as a result, uniform heat collection can be obtained.

以下、図面について本発明の実施の形態を詳細に説明する。図１は本発明の空気式ソーラーシステムの要部の斜視図で、後付けタイプの集熱部２８を図１４に示すように複数を並列に並べ、これらをそれぞれ棟ダクト４に接続するもので、図中２９は集熱部２８の端部に形成する空気入口である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the main part of the pneumatic solar system of the present invention, in which a plurality of retrofit type heat collecting portions 28 are arranged in parallel as shown in FIG. 14, and these are connected to the ridge duct 4 respectively. In the figure, 29 is an air inlet formed at the end of the heat collecting section 28.

なお、空気式ソーラーシステム全体としては、図示は省略するが、図１２に示すように、内部に逆流防止兼流路切換えダンパー６、ファン７及び流路切換えダンパー８を設けたハンドリングボックス５を屋根裏空間である小屋裏に設置し、ハンドリングボックス５の流路切換えダンパー８の流出側の一方は排気ダクト９により屋外に開口する。   Although the illustration of the pneumatic solar system as a whole is omitted, as shown in FIG. 12, a handling box 5 provided with a backflow prevention and flow path switching damper 6, a fan 7 and a flow path switching damper 8 is provided in the attic. One side of the outflow side of the flow path switching damper 8 of the handling box 5 is opened outdoors by an exhaust duct 9.

また、ハンドリングボックス５の逆流防止兼流路切換えダンパー６の流入側は、前記棟ダクト４に連通させる接続ダクトと室内２０からの循環ダクト１８とに選択的に接続し、流路切換えダンパー８の流出側の他の一方を立下りダクト１０の上端に連結する。   Further, the inflow side of the backflow prevention / flow path switching damper 6 of the handling box 5 is selectively connected to a connection duct communicating with the building duct 4 and a circulation duct 18 from the room 20, so that the flow path switching damper 8 The other one on the outflow side is connected to the upper end of the falling duct 10.

立下りダクト１０の下端は床下蓄熱体としての土間コンクリート１１と床パネル１２との間の空気流通空間１３に開口した。さらに、該空気流通空間１３から室内への床吹出口１４を設けた。   The lower end of the falling duct 10 opened to the air circulation space 13 between the soil concrete 11 as the underfloor heat storage body and the floor panel 12. Furthermore, a floor outlet 14 from the air circulation space 13 to the room was provided.

本発明は、前記並列して棟ダクト４に接続する集熱部２８の空気入口２９には前記棟ダクト４に並行して風量調整用の入口ダクト３０を設けて該入口ダクト３０により共通させ、この入口ダクト３０の空気取入れ開口３１は下向きに開口した。 The present invention is common by the inlet duct 30 provided with an inlet duct 30 for adjusting the air volume in parallel to the building duct 4 to the air inlet 29 of the heat collector 28 to be connected to the building duct 4 the parallel, The air intake opening 31 of the inlet duct 30 was opened downward.

図２〜図４は詳細を示すもので、集熱部２８は垂木３２の上に貼設した野地板３３の上に芯木３４を間隔を存して並べて空間を確保し、その上に集熱板３５を貼設して形成した。この集熱板３５にはアルミ、亜鉛、トタン、鋼板、カラーステンレスなどの長尺金属板が採用できるが、日射吸収率を考慮して暗褐色系のものが好ましい。このようにして区画された複数の集熱部２８が並列して形成され、棟ダクト４の端に接続する。   2 to 4 show the details, and the heat collecting section 28 secures a space by arranging the cores 34 on the field board 33 affixed on the rafter 32 with a space therebetween, and collects the heat on the top. The hot plate 35 was formed by pasting. The heat collecting plate 35 may be a long metal plate such as aluminum, zinc, tin, steel plate, color stainless steel, etc., but preferably has a dark brown color in consideration of the solar radiation absorption rate. A plurality of heat collecting portions 28 partitioned in this way are formed in parallel and connected to the end of the ridge duct 4.

入口ダクト３０は集熱部２８に連続するチャンバー部であり、集熱部２８の空気入口２９は共通化させるため、並列して棟ダクト４に接続する集熱部２８に対して横方向に流すように形成される。   The inlet duct 30 is a chamber part continuous with the heat collecting part 28, and the air inlet 29 of the heat collecting part 28 is made to flow in the horizontal direction with respect to the heat collecting part 28 connected to the ridge duct 4 in parallel. Formed as follows.

本実施形態では、入口ダクト３０の上面も集熱板３５で形成して集熱面とするようにした。なお、入口ダクト３０は集熱部２８に連続するもので、この集熱板３５も集熱部２８のものを延長利用できる。   In the present embodiment, the upper surface of the inlet duct 30 is also formed by the heat collecting plate 35 to be a heat collecting surface. The inlet duct 30 is continuous with the heat collecting section 28, and the heat collecting plate 35 can be extended from the heat collecting section 28.

また、前記従来例と同じく、ガラス２３で覆い、温室空気越しの高温集熱を行う高温集熱面とそれ以外の低温集熱面とに分かれるものとした。図中３７はガラス固定金物である。   Further, as in the conventional example, it is covered with glass 23 and divided into a high-temperature heat collecting surface that collects high-temperature heat through the greenhouse air and other low-temperature heat collecting surfaces. In the figure, 37 is a glass fixing hardware.

このようにして、入口ダクト３０を設けることで集熱部２８の空気入口２９の開口面積および配置を調整し、風量調整を行うことができる。   Thus, by providing the inlet duct 30, the opening area and arrangement of the air inlet 29 of the heat collecting section 28 can be adjusted, and the air volume can be adjusted.

図１１は図１に対応した風量調整の特性を示す説明図で、（ａ）は入口ダクト３０を設けない場合で、５番が一番風量が多く、1番が少ない。５→１へ徐々に減っていく。   FIG. 11 is an explanatory diagram showing the air volume adjustment characteristics corresponding to FIG. 1. FIG. 11A shows the case where the inlet duct 30 is not provided, and No. 5 has the largest air volume and No. 1 has the smallest. It gradually decreases from 5 to 1.

（ｂ）は空気取入れ開口３１を１番に対応させて設けた場合で、１番が一番風量が多く、５番が少ない。１→５へ徐々に減っていく。   (B) is the case where the air intake opening 31 is provided corresponding to No. 1, and No. 1 has the largest air volume and No. 5 has the smallest. Decrease gradually from 1 to 5.

（ｃ）は空気取入れ開口３１を適宜の間隔で複数設けた場合で、ほぼ均一になる。   (C) is a case where a plurality of air intake openings 31 are provided at appropriate intervals, and is substantially uniform.

なお、棟ダクト４とハンドリングボックス５のファン７の関係は、その接続位置は端部になるが、図５、図６に示すように左右および前後において可能である。また、端部は必ずしも端になる必要がなく、少し中心によってもかまわない。   The relationship between the ridge duct 4 and the fan 7 of the handling box 5 is possible at the left and right and front and rear as shown in FIGS. Further, the end portion does not necessarily need to be an end, and may be slightly centered.
