Consequently, the plate 1 allows water in a fixed temperature range to flow into an underground water storage space 7.

Description

本発明は、地中熱源ヒートポンプシステムの水熱源として利用される地中貯水空間に、地中の温度（約１５℃）に近い一定の温度帯（１０℃〜２０℃）内に収まる水を供給可能とする、地中に埋設されて使用される地下水路形成用のプレートに関する。   The present invention supplies water that falls within a certain temperature zone (10 ° C. to 20 ° C.) close to the underground temperature (about 15 ° C.) to the underground water storage space used as the water heat source of the underground heat source heat pump system. The present invention relates to a plate for forming an underground water channel that can be used by being buried in the ground.

従来より、地中熱をヒートポンプの熱源として利用する地中熱源ヒートポンプシステムが知られている。地中熱源ヒートポンプシステムは、地中の温度が、季節に関わりなく１５℃前後に保たれていることに着目し、夏は地中熱を冷熱源（ヒートシンク）として、冬は地中熱を温熱源（ヒートソース）として、それぞれ空調・給湯・融雪等の熱源として利用するものである。特に、近年、地中熱源ヒートポンプシステムは、環境問題への意識の高まりと共に、二酸化炭素の排出量が少なく、節電効果が非常に高い再生可能エネルギー利用技術として注目を集めてきている。   Conventionally, a geothermal heat source heat pump system that uses geothermal heat as a heat source of a heat pump is known. Focusing on the fact that the underground heat source heat pump system maintains the underground temperature at around 15 ° C regardless of the season, the underground heat is used as a cold heat source (heat sink) in summer, and the underground heat is heated in winter. As a heat source, it is used as a heat source for air conditioning, hot water supply, snow melting, etc., respectively. In particular, in recent years, geothermal heat source heat pump systems have attracted attention as a renewable energy utilization technology that has a low carbon dioxide emission and a very high power-saving effect, along with increasing awareness of environmental problems.

しかしながら、地中熱源ヒートポンプシステムは、地中で熱交換を行うことから、熱交換器等を地中に埋設する必要があり、熱交換器等を埋設するためのスペースの確保が必要になるという問題があった。空調の熱源が必要とされるのは、主に、都市部などの人口密集地であって地価の高いところであるため、このスペースの確保は、特に、対費用効果の点から問題となってしまっている。   However, since the underground heat source heat pump system performs heat exchange in the ground, it is necessary to embed a heat exchanger or the like in the ground, and it is necessary to secure a space for burying the heat exchanger or the like. There was a problem. The need for an air conditioning heat source is mainly in densely populated areas such as urban areas where land prices are high, so securing this space has become a problem, particularly in terms of cost effectiveness. ing.

なお、この場合、地価の問題を解消すべく、熱交換器を直状のＵ字型パイプとし、これを地中深くに埋設することによって、熱交換器としての機能を確保し、かつ、埋設するためのスペースを最小化する方法も考えられるが、地中深く掘削するのにも膨大な費用が掛かるため、この方法も、対費用効果の点から問題があることが認められている。   In this case, in order to solve the problem of land prices, the heat exchanger is a straight U-shaped pipe, which is buried deep in the ground to ensure the function as a heat exchanger and buried. Although a method for minimizing the space required to do this is also conceivable, it is recognized that this method is also problematic from the viewpoint of cost effectiveness because it takes a huge amount of money to dig deep into the ground.

本願発明者は、このような実情のもと、対費用効果の問題を解消し、かつ、地中熱の有効利用が期待できる方法について鋭意検討を重ねた。その結果、本願発明者は、人工的に地下水路を形成するプレート（地下水路形成用のプレート）を、ビル等の建築物の基礎地盤面の上に置くことによって、以上のような問題を解決することができるという知見を得、本発明を創作するに至った。   Under such circumstances, the inventor of the present application has made extensive studies on a method that can solve the problem of cost effectiveness and can be expected to effectively use underground heat. As a result, the inventor of the present application solves the above problems by placing a plate (a plate for forming a groundwater channel) that artificially forms a groundwater channel on the foundation ground surface of a building or the like. The inventor has obtained knowledge that the present invention can be performed, and has led to the creation of the present invention.

なお、本発明を出願するにあたって、本願発明者や出願人において過去の特許文献等を調査したところ、地中熱源を利用した技術に関し、下記の文献を発見することができたが、本発明に係る技術的思想等を詳述した特許文献については発見することができなかった。   In addition, when filing the present invention, the inventors of the present application and the applicant investigated past patent documents and the like, and found the following documents regarding the technology using the underground heat source. It was not possible to find a patent document detailing such technical ideas.

In the meantime, heat exchange between the flowing water and the ground around the plate allows water that falls within a certain temperature zone to flow out of the water channel of the plate. It is a feature.

また、本発明に係る地下水路形成用のプレートは、凹部と凸部を有する波板によって構成されており、前記凹部が、当該プレートの上面において、当該プレートの一端から他端へと水を流すための水路となり、当該水路を水が流れる間に、この流れる水と当該プレートの周りの地中との熱交換が行われることによって、一定の温度帯内に収まる水を当該プレートの水路から流し出すことができるようになっていることも特徴としている。   Moreover, the plate for groundwater channel formation according to the present invention is constituted by a corrugated plate having a concave portion and a convex portion, and the concave portion allows water to flow from one end of the plate to the other end on the upper surface of the plate. As the water flows through the water channel, heat exchange between the flowing water and the ground around the plate causes water contained within a certain temperature zone to flow from the water channel of the plate. It is also characterized by being able to put out.

本発明によれば、地中熱源ヒートポンプシステムの水熱源として利用される地中貯水空間に、地中の温度（約１５℃）に近い一定の温度帯（１０℃〜２０℃）内に収まる水を供給可能とする、地中に埋設されて使用される地下水路形成用のプレートを提供することができる。   According to the present invention, water that fits in a constant temperature zone (10 ° C. to 20 ° C.) close to the underground temperature (about 15 ° C.) in the underground water storage space used as the water heat source of the underground heat source heat pump system. It is possible to provide a plate for forming an underground water channel that is used while being buried in the ground.

また、本発明では、地下水路形成用のプレートを、ビル等の建築物の基礎地盤面の上に置くこととしているので、本発明によれば、熱交換器等を埋設するために、別途、建築工事の工程を増やす必要がない。そのため、費用抑制や工期短縮の点においても大きな利点をもたらすことができる。   Further, in the present invention, since the plate for forming a groundwater channel is placed on the foundation ground surface of a building such as a building, according to the present invention, in order to embed a heat exchanger or the like separately, There is no need to increase the construction process. Therefore, a great advantage can be brought about in terms of cost reduction and shortening of the construction period.

地中熱源ヒートポンプシステム１の概略図１。1 is a schematic diagram 1 of a ground source heat pump system 1. 地中熱源ヒートポンプシステム１の概略図２。Schematic 2 of the underground heat source heat pump system 1.

以下、本発明に係る地下水路形成用のプレートを実施するための形態について説明する。地下水路形成用のプレート１は、図１に示されているように、凹部と凸部を有する波板によって構成されており、掘削工事によって現れた基礎地盤面の上に敷設され、地中に埋設されている。   Hereinafter, the form for implementing the plate for groundwater channel formation concerning the present invention is explained. As shown in FIG. 1, the plate 1 for forming a groundwater channel is constituted by a corrugated plate having a concave portion and a convex portion, and is laid on a foundation ground surface that has appeared by excavation work, Buried.

プレート１には、その一端に入水路２が、その他端に出水路３がそれぞれ付設されている。そして、入水路２の端部は、図１や図２に示されているように、水溜まり４、及び、配水管５を介して、雨水等の自然水を貯められるようになっている地下自然水槽６と接続している。これにより、プレート１は、地下自然水槽６内の水を、その一端において受け、その上面の凹部に流すことができるような構成となっている。   The plate 1 is provided with a water inlet 2 at one end and a water outlet 3 at the other end. And as shown in FIG. 1 and FIG. 2, the end of the water inlet 2 is an underground natural water that can store natural water such as rainwater through a water reservoir 4 and a water distribution pipe 5. It is connected to the aquarium 6. Thereby, the plate 1 is configured to receive the water in the underground natural water tank 6 at one end and to flow into the concave portion on the upper surface thereof.

また、出水路３は、水熱源として利用される水を貯められるようになっている地中貯水空間７と接続している。これにより、プレート１は、その上面の凹部が、プレート１の一端から他端へと水を流すための水路となり、入水路２から受けた水を、地中貯水空間７へと流し出すことができるようになっている。   Further, the water discharge channel 3 is connected to an underground water storage space 7 in which water used as a water heat source can be stored. As a result, the concave portion of the upper surface of the plate 1 becomes a water channel for flowing water from one end of the plate 1 to the other end, and the water received from the water intake channel 2 can flow out into the underground water storage space 7. It can be done.

なお、これらの図において、８は、熱交換器として機能するパイプを示しており、ここでは図示されない地上のヒートポンプと接続している。これにより、本実施形態では、地中貯水空間７に貯められた水を、ヒートポンプシステムの水熱源として利用することができるようになっている。なお、ここで図示されているパイプ８は、直状のＵ字型パイプとなっているが、熱交換効率をより高めるため、地中貯水空間７内におけるパイプ８の形状を螺旋形等としても良い。   In these drawings, reference numeral 8 denotes a pipe that functions as a heat exchanger, and is connected to a ground heat pump not shown here. Thereby, in this embodiment, the water stored in the underground water storage space 7 can be utilized as a water heat source of the heat pump system. The pipe 8 shown here is a straight U-shaped pipe. However, in order to further improve the heat exchange efficiency, the pipe 8 in the underground water storage space 7 may have a spiral shape or the like. good.

そして、本実施形態においては、ここでは図示されないポンプ等によって、適宜、地中貯水空間７の水を吸い上げて利用する等して、地中貯水空間７内の水を地上に排出するようになっているので、プレート１の上面における水流が、自然と生じるようになっている。   In this embodiment, the water in the underground water storage space 7 is discharged to the ground by appropriately sucking and using the water in the underground water storage space 7 by a pump or the like not shown here. Therefore, the water flow on the upper surface of the plate 1 naturally occurs.

なお、以上の実施形態において、地下自然水槽６は、管路（図示せず）と接続しており、当該管路を介して、ビル等の建築物の屋根に降り注いだ雨水を、その内部に集められるような構成となっている。   In addition, in the above embodiment, the underground natural water tank 6 is connected with a pipe line (not shown), and the rainwater poured on the roof of a building such as a building is passed through the pipe line. It is configured to be collected.

本発明は、以上に説明したような構成となっているので、プレート１の上面を水が流れる間に、この流れる水とプレート１の周りの地中との熱交換が行われ、地中貯水空間７に、地中の温度（約１５℃）に近い一定の温度帯（１０℃〜２０℃）内に収まる水を供給することができる。そのため、この地中貯水空間７に貯められる水も、常に、一定の温度帯内に収まるため、この水を地中熱源ヒートポンプシステムの水熱源として利用することができる。   Since the present invention is configured as described above, heat exchange is performed between the flowing water and the ground around the plate 1 while the water flows on the upper surface of the plate 1. Water that falls within a certain temperature range (10 ° C. to 20 ° C.) close to the underground temperature (about 15 ° C.) can be supplied to the space 7. Therefore, since the water stored in the underground water storage space 7 is always within a certain temperature range, this water can be used as a water heat source of the underground heat source heat pump system.

また、本発明は、地下水路形成用のプレート１を、ビル等の建築物の基礎地盤面の上に置くことで、熱交換を行うこととしているので、従来のように、建築工事とは別に熱交換器を埋設等する工程を必要とせず、費用抑制や工期短縮の点においても大きな利点をもたらすことができる。   Further, according to the present invention, heat exchange is performed by placing the plate 1 for forming a groundwater channel on the foundation ground surface of a building such as a building. A process for embedding a heat exchanger or the like is not required, and a great advantage can be brought about in terms of cost reduction and shortening the work period.

さらに、本発明では、ヒートポンプシステムの熱源として地中の水を利用しているが、その水は、雨水等の自然水を人工的に収集したものであって、従来から存在する地下水脈に由来するものではない。そのため、従来から存在する地下水脈を汚染したり、流量の低下を招いたりすることもなく、地中の水を熱源として利用することができる。   Furthermore, in the present invention, underground water is used as a heat source of the heat pump system, but the water is artificially collected natural water such as rainwater, and is derived from a conventional underground water vein. Not what you want. Therefore, underground water can be used as a heat source without contaminating existing groundwater veins or causing a decrease in flow rate.

なお、本発明は、当然ながら、以上の実施形態で説明した地下水路形成用のプレート１に限定されるものではない。さらに、本発明の範囲には、本発明の技術的思想が具現化されたものも含まれるものとする。   The present invention is naturally not limited to the underground water channel forming plate 1 described in the above embodiment. Further, the scope of the present invention includes those in which the technical idea of the present invention is embodied.
