Description

本発明は、従来のものよりも、費用抑制や工期短縮等の点において大きな利点をもたらすことができる、地中熱源ヒートポンプシステムにおいて利用される地中埋設型の熱交換器に関する。   The present invention relates to an underground heat exchanger used in an underground heat source heat pump system, which can provide significant advantages in terms of cost reduction, shortening of work period, and the like as compared with the conventional one.

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.

ところで、このような地中熱源ヒートポンプシステムの実施態様の一つとして、従来より、長尺（１００ｍ程度）のＵ字型パイプを熱交換器として地中に埋設し、このＵ字型パイプ内に流す液媒（液媒体）によって、地中との熱交換を行い、ヒートポンプの熱源として利用するシステムが知られている。   By the way, as one embodiment of such a subsurface heat source heat pump system, conventionally, a long (about 100 m) U-shaped pipe is buried in the ground as a heat exchanger, and the U-shaped pipe is embedded in the U-shaped pipe. There is known a system for exchanging heat with the ground by a flowing liquid medium (liquid medium) and using it as a heat source of a heat pump.

しかしながら、このようなシステムでは、Ｕ字型パイプを地中深くに埋設する必要があるため、掘削工事や埋設工事等に膨大な費用を必要とするという問題があった。   However, in such a system, since it is necessary to embed the U-shaped pipe deep in the ground, there is a problem that enormous costs are required for excavation work and burial work.

本願発明者は、このような実情のもと、Ｕ字型パイプが有する問題を解消することができる地中埋設型の熱交換器について鋭意検討を重ねた。その結果、本願発明者は、鋼板と、当該鋼板の片側面に付設されたコンクリート層と、当該コンクリート層内に埋設されたパイプとからなるパネル型の熱交換器によって、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 present inventor has intensively studied an underground heat exchanger that can solve the problem of the U-shaped pipe. As a result, the inventor of the present application solves the above problems by a panel-type heat exchanger comprising a steel plate, a concrete layer attached to one side of the steel plate, and a pipe embedded in the concrete layer. The knowledge that it can be solved was obtained, and the present invention was created.

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、地中熱源ヒートポンプシステムに関し、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 applying the present invention, the present inventors and applicants investigated past patent documents, etc., and found the following documents regarding the underground heat source heat pump system. It was not possible to find a patent document detailing a specific idea.

以下、本発明に係る地中熱源ヒートポンプ用のパネル型熱交換器を実施するための形態について説明する。図１は、本実施形態に係るパネル型熱交換器１を示したものである。このパネル型熱交換器１は、図示されているように、基本的に、鋼板２と、鋼板２の片側面に付設されたコンクリート層３と、コンクリート層３内に埋設されたパイプ４とから構成されている。   Hereinafter, the form for implementing the panel type heat exchanger for underground heat source heat pumps concerning this invention is demonstrated. FIG. 1 shows a panel heat exchanger 1 according to this embodiment. As shown in the figure, this panel heat exchanger 1 basically includes a steel plate 2, a concrete layer 3 attached to one side of the steel plate 2, and a pipe 4 embedded in the concrete layer 3. It is configured.

鋼板２は、コンクリート層３が付設された面とは反対側の面に、プレート状のリブ５を複数有している。また、ここでは図示されないが、鋼板２には、コンクリート層３が付設される面側に、鋼板２とコンクリート層３とのズレを防止すると共に、これらを合成化してその剛性を高めることを目的とした突設部も複数設けられている。   The steel plate 2 has a plurality of plate-like ribs 5 on the surface opposite to the surface to which the concrete layer 3 is attached. Although not shown here, the steel plate 2 has a purpose of preventing the deviation between the steel plate 2 and the concrete layer 3 on the surface side where the concrete layer 3 is attached and synthesizing them to increase the rigidity thereof. A plurality of protruding portions are also provided.

パイプ４は、熱交換に利用される液媒（液媒体）を通すためのものであって、その内部を通る液媒を、パネル型熱交換器１の外から取り入れるための取入口６と、取入口６から取り入れた液媒を、パネル型熱交換器１の外に放出するための放出口７とを有している。なお、パイプ４については、熱交換効率を高めるため、熱伝導率の良い鋼鉄製とすることが好ましい。   The pipe 4 is for passing a liquid medium (liquid medium) used for heat exchange, and an inlet 6 for taking in the liquid medium passing through the inside from the outside of the panel heat exchanger 1; It has a discharge port 7 for discharging the liquid medium taken in from the intake port 6 to the outside of the panel heat exchanger 1. In addition, about the pipe 4, in order to improve heat exchange efficiency, it is preferable to use steel made from a good heat conductivity.

そして、以上のような構成をしたパネル型熱交換器１は、地中に埋設されて、地中熱源ヒートポンプ用の熱交換器として利用されると同時に、鋼板とコンクリート層という強度のある合成材という特徴を活かし、建築・土木用の建材として利用できるようになっている。   The panel heat exchanger 1 configured as described above is embedded in the ground and used as a heat exchanger for the underground heat source heat pump, and at the same time has a strong composite material such as a steel plate and a concrete layer. Taking advantage of this feature, it can be used as a building material for construction and civil engineering.

具体的には、図２に示したように複数のパネル型熱交換器１を並べて、パネル型熱交換器１の鋼板２側を土壌と接する側とし、図３に示したように、金属枠８で固定して、基礎地盤における土止めの壁として利用したり、図４に示したような建築物の地下室の外壁面として利用したりする方法が考えられる。また、図５に示したような斜面９の擁壁として利用したりする方法も考えられ、パネル型熱交換器１は、垂直に立てた状態で利用する以外にも、斜めにした状態で利用することも可能である。   Specifically, a plurality of panel type heat exchangers 1 are arranged as shown in FIG. 2, and the steel plate 2 side of the panel type heat exchanger 1 is set as the side in contact with the soil. As shown in FIG. A method of fixing at 8 and using as a wall for earth retaining on the foundation ground or as an outer wall surface of a basement of a building as shown in FIG. 4 can be considered. Moreover, the method of using as a retaining wall of the slope 9 as shown in FIG. 5 is also considered, and the panel type heat exchanger 1 is used in an inclined state in addition to being used in a vertical state. It is also possible to do.

なお、この場合において、リブ５は、鋼板２を補強し、パネル型熱交換器１全体の剛性を高めると共に、熱交換時の放熱板（フィン）として機能するという役割も有することになる。また、リブ５は、そのプレート面が水平方向を向くように配置されて、地中に埋設されることになるため、埋設後、パネル型熱交換器１の横ズレを防止するという機能も有することになる。   In this case, the rib 5 reinforces the steel plate 2 and increases the rigidity of the panel heat exchanger 1 as a whole, and also functions as a heat radiating plate (fin) during heat exchange. Moreover, since the rib 5 is disposed so that the plate surface thereof faces in the horizontal direction and is embedded in the ground, the rib 5 also has a function of preventing lateral displacement of the panel heat exchanger 1 after being embedded. It will be.

また、以上の実施形態において、取入口６と放出口７とは、図１や図２に示されているように、コンクリート層３の同一側面上に設けられていることが好ましい。また、ここでは図示されないが、取入口６と放出口７との端部には、公知の接続部材を利用できるように、それぞれネジ山が切られていることが好ましい。これらは、このような構成とすることで、隣り合うパネル型熱交換器１のパイプ４同士の接続を容易に行うことができるからである。さらに、この場合において、前記の接続部材として、蛇腹管等の可撓性のパイプを使用することが好ましい。これは、このような構成とすることで、地震や不等沈下などによって、万が一、パネル型熱交換器１の位置がズレてしまった場合であっても、隣り合うパネル型熱交換器１へと、パイプ４を介して問題なく熱媒を流し続けることができるからである。   Moreover, in the above embodiment, it is preferable that the intake port 6 and the discharge port 7 are provided on the same side surface of the concrete layer 3 as shown in FIG. 1 and FIG. Although not shown here, it is preferable that the end portions of the intake port 6 and the discharge port 7 are respectively threaded so that a known connection member can be used. This is because the pipes 4 of adjacent panel heat exchangers 1 can be easily connected to each other by adopting such a configuration. Further, in this case, it is preferable to use a flexible pipe such as a bellows tube as the connecting member. By adopting such a configuration, even if the position of the panel heat exchanger 1 is shifted due to an earthquake or unequal subsidence, the panel type heat exchanger 1 is moved to the adjacent panel heat exchanger 1. This is because the heating medium can continue to flow through the pipe 4 without any problem.

さらに、以上の実施形態において、パイプ４は、図１や図２に示されているように、直管と曲管との組合せによって蛇行するように構成されていることが好ましい。これは、このような構成とすることで、地中の熱とパイプ４内の液媒との熱交換が効率良く行われ、パネル型熱交換器１が熱交換器としての機能を十分に発揮することができるからである。なお、パイプ４の構成については、当然ながら本実施形態で示したものに限定されることは無く、例えば、渦巻形などにすることも可能である。   Furthermore, in the above embodiment, the pipe 4 is preferably configured to meander by a combination of a straight pipe and a curved pipe, as shown in FIGS. With this configuration, heat exchange between the underground heat and the liquid medium in the pipe 4 is efficiently performed, and the panel heat exchanger 1 sufficiently exhibits the function as a heat exchanger. Because it can be done. Of course, the configuration of the pipe 4 is not limited to that shown in the present embodiment, and may be a spiral shape, for example.

また、以上の実施形態において、鋼板２は、そのコンクリート層３が付設される面、及び／又は、コンクリート層３が付設される面とは反対側の面の大きさが、１０００ｍｍ〜３０００ｍｍの範囲内にあり、かつ、コンクリート層３は、その厚さが４０ｍｍ〜１００ｍｍの範囲内にあることが好ましい。これは、このような構成とすることで、図３〜図５で示したような利用方法等において、建材として取り扱いやすく、特に利用し易い大きさ、重さ、強度等を有することになるからである。   Moreover, in the above embodiment, the steel plate 2 has a size of a surface on which the concrete layer 3 is attached and / or a surface opposite to the surface on which the concrete layer 3 is attached in a range of 1000 mm to 3000 mm. It is preferable that the concrete layer 3 is within the range of 40 mm to 100 mm. This is because such a configuration makes it easy to handle as a building material in the usage method shown in FIGS. It is.

なお、本実施形態において、パイプ４は、鋼板２に密接している必要がある。これは、パネル型熱交換器１において、鋼板２の側が熱交換を行う面となるため、パイプ４を鋼板２に密着させることにより、より効率よく熱交換が行われることが期待できるからである。   In the present embodiment, the pipe 4 needs to be in close contact with the steel plate 2. This is because in the panel-type heat exchanger 1, since the side of the steel plate 2 serves as a surface for heat exchange, it can be expected that heat exchange is performed more efficiently by bringing the pipe 4 into close contact with the steel plate 2. .

なお、本発明は、当然ながら、以上の実施形態で説明したパネル型熱交換器１や、図示されたパネル型熱交換器１に限定されるものではなく、また、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。   In addition, this invention is not limited to the panel type heat exchanger 1 demonstrated in the above embodiment, or the panel type heat exchanger 1 illustrated in the drawing, and the scope of the present invention includes: What embodied the technical idea of this invention shall also be included.

本発明に係るパネル型熱交換器１は、以上のような構成となっており、地中に埋設された際、熱伝導率の低いコンクリート層３側が、地下室等の地下空間側に面することになるため、本発明に係るパネル型熱交換器１を利用すれば、パイプ４内における液媒の熱エネルギーの損失が少なく、効率良く熱交換を行うことができる。   The panel type heat exchanger 1 according to the present invention is configured as described above, and when embedded in the ground, the concrete layer 3 side having low thermal conductivity faces the underground space side such as a basement. Therefore, if the panel heat exchanger 1 according to the present invention is used, the heat energy loss of the liquid medium in the pipe 4 is small and heat exchange can be performed efficiently.

また、本発明に係るパネル型熱交換器１は、その単体を埋設前にユニットとして並べてモジュール化することができ、これにより地中への埋設作業の効率を高めることができる。また、モジュール化する際に、パネル型熱交換器１を、直列や並列、またはその併用といった組み合わせとすることで、要求される熱交換能力に応じて、パネル型熱交換器１を配置することもできる。   Further, the panel heat exchanger 1 according to the present invention can be modularized by arranging the single unit as a unit before being embedded, thereby increasing the efficiency of the underground operation. In addition, when modularizing, the panel heat exchanger 1 is arranged in series, parallel, or a combination thereof, so that the panel heat exchanger 1 is arranged according to the required heat exchange capacity. You can also.

さらに、本発明に係るパネル型熱交換器１は、従来のＵパイプ型地中熱交換器と異なり、建物等の基礎工事時に、これを埋設することができるので、改めて地中深く掘削工事を行う必要が無く、工事費用を抑制し、工期を短縮することができる。さらに、本実施形態に係るパネル型熱交換器１は、従来のＵパイプ型地中熱交換器と異なり、工場での大量生産が可能なため、この点からも工事費用を抑制し、工期を短縮することができる。   Furthermore, unlike the conventional U-pipe type underground heat exchanger, the panel type heat exchanger 1 according to the present invention can be buried at the time of foundation work such as a building. There is no need to do this, so construction costs can be reduced and the construction period can be shortened. Furthermore, unlike the conventional U-pipe type underground heat exchanger, the panel type heat exchanger 1 according to the present embodiment can be mass-produced at the factory. It can be shortened.
