Description
この発明は、太陽熱地中蓄熱装置に関する。 The present invention relates to a solar thermal underground heat storage device.
従来、太陽熱地中蓄熱装置には蓄熱槽と熱媒体を循環させるポンプが使われている。 Conventionally, a solar heat storage device uses a heat storage tank and a pump for circulating a heat medium.
地下に蓄熱槽を設置するためには、基礎の部分も含めて土地を掘り起こす必要があり、大規模な蓄熱槽を設置することは技術的及びコスト的に困難である。 In order to install a heat storage tank in the basement, it is necessary to dig up the land including the foundation part, and it is technically and costly difficult to install a large-scale heat storage tank.
熱媒体をポンプで循環させる装置は、ポンプを動かすために電力が必要である。 An apparatus that circulates the heat medium with a pump requires electric power to operate the pump.
本発明は、蓄熱槽もポンプも使用せずに、簡易な構造で太陽熱を利用して太陽熱を地中に蓄熱する装置を実現することを目的としている。 An object of the present invention is to realize an apparatus for storing solar heat in the ground using solar heat with a simple structure without using a heat storage tank or a pump.
本発明（請求項１）の太陽熱地中蓄熱装置は、下部がＵ字状で上部がそれぞれ逆Ｊ字状になっておりその高さが異なる管の下部を、少なくとも高い方の地上部は太陽光を受ける位置で、地中に埋め、太陽光を受けることによって暖められて軽くなる地上部の管の内部の空気の層の厚さが異なるために、軽い空気の層が厚い地上部が高い方へ低い方から管内の空気が流れていくことを利用して蓄熱する構成とした。 The solar thermal underground heat storage device of the present invention (Claim 1) has a U-shaped lower part and an inverted J-shaped upper part, respectively. The above-ground part with a thick light air layer is high because the thickness of the air layer inside the above-ground pipe that is buried in the ground and warmed and lightened by receiving sunlight is different at the light receiving position. It was set as the structure which accumulates heat | fever using the air in a pipe | tube flowing from the lower one to the direction .
本発明（請求項２）の太陽熱地中蓄熱装置は、逆Ｊ字状の外管の下部に内管を入れ、内管の上部を外管の外に出し、内管の下部で内管の内外がつながっているものを、太陽光を受ける位置で、地中に埋め、太陽光を受けることによって暖められて軽くなる地上部の管の内部の空気の層の厚さが異なるために、軽い空気の層が厚い外管へ内管から管内の空気が流れていくことを利用して蓄熱する構成とした。 In the solar thermal underground heat storage device of the present invention (invention 2), the inner tube is placed in the lower portion of the inverted J-shaped outer tube, the upper portion of the inner tube is taken out of the outer tube, and the inner tube is It is light because the thickness of the air layer inside the tube of the above-ground part that is warmed and lightened by receiving sunlight is buried in the ground where the inside and outside are connected, buried in the ground Heat is stored using the fact that the air in the pipe flows from the inner pipe to the outer pipe where the air layer is thick .
本発明（請求項３）の太陽熱地中蓄熱装置は、逆Ｊ字状の外管の下部に内管を入れ、内管の上部を外管に接合し、その接合部の下部で内管と外部との間の空間が外管の外につながるように管が設けられており、その管は下方向に開口しており、内管の下部で内管の内外がつながっているものを、太陽光を受ける位置で、地中に埋め、太陽光を受けることによって暖められて軽くなる地上部の管の内部の空気の層の厚さが異なるために、軽い空気の層が厚い外管の上部につながる内管へ下部の外管から管内の空気が流れていくことを利用して蓄熱する構成とした。 The solar thermal underground heat storage device of the present invention (Claim 3) includes an inner tube placed in a lower portion of an inverted J-shaped outer tube, an upper portion of the inner tube is joined to the outer tube, and an inner tube is joined to the lower portion of the joined portion. A pipe is provided so that the space between the outside and the outside pipe is connected to the outside, and the pipe opens downward, and the inside and outside of the inside pipe is connected to the bottom of the inside pipe. At the light receiving position, the air layer inside the above-ground pipe that is buried in the ground and warmed and lightened by receiving sunlight is different, so the light air layer is the upper part of the thick outer pipe It was set as the structure which heat-stores using the air in a pipe | tube flowing from the lower outer pipe | tube to the inner pipe | tube connected to.
本発明の太陽熱地中蓄熱装置は、構造物としての蓄熱槽を持たず、地中に蓄熱するもので、管を深く埋めることにより蓄熱量を増やすことが可能である。 The solar thermal underground heat storage device of the present invention does not have a heat storage tank as a structure and stores heat in the ground, and it is possible to increase the amount of heat storage by deeply filling the pipe.
本発明の太陽熱地中蓄熱装置は、太陽熱で暖められた空気を太陽熱を動力源として地中を通過させて地中を暖めるもので、電力等のエネルギーを使用しない。 The solar thermal underground heat storage device of the present invention warms the ground by passing the air heated by solar heat through the ground using solar heat as a power source, and does not use energy such as electric power.
本発明の太陽熱地中蓄熱装置は、構造物としての蓄熱槽を持たないので施工が簡単である。特に、請求項２及び請求項３の太陽熱地中蓄熱装置は地中への埋設が容易である。
Since the solar thermal underground heat storage device of the present invention does not have a heat storage tank as a structure, construction is simple. In particular, the solar thermal underground heat storage device according to
以下、本発明の太陽熱地中蓄熱装置の実施の形態を実施例により説明する。 Hereinafter, embodiments of the solar thermal underground heat storage device of the present invention will be described with reference to examples.
図１は、本発明（請求項１）の太陽熱地中蓄熱装置の実施例を示す側面断面図である。 FIG. 1 is a side sectional view showing an embodiment of the solar thermal underground heat storage device of the present invention (Claim 1).
太陽光を受けると管の内部の空気が暖められて膨張し比重が小さくなる。ここで、地上部の管の高さが異なるため、比重が小さい空気の層の厚さは地上部の管の高さが高い方の管が厚くなり、管の最下部において、地上部の管の高さが高い方の管の側の気圧が低くなり、気圧が低い方に空気が流れていく。太陽光を受けて管の内部が暖められている間、この過程が繰り返されて、温められた空気が管の中を通過し、地中を暖める。 When sunlight is received, the air inside the tube is warmed and expanded to reduce the specific gravity. Here, because the height of the above-ground pipe is different, the thickness of the air layer having a small specific gravity is thicker in the pipe with the higher height of the above-ground pipe. The pressure on the side of the pipe with the higher height becomes lower, and the air flows to the lower pressure side. This process is repeated while the inside of the pipe is warmed by receiving sunlight, and warmed air passes through the pipe and warms the ground.
地下５メートルより深いところでは、地中の温度はほぼ一定で、その温度は、その地点の年平均気温にほぼ等しいといわれている。夏季の日中の気温は地中温度よりかなり高温である上、さらに太陽光で暖められた空気を地中を通過させるので、地中温度を相当程度高めることができる。 At a depth of 5 meters below the ground, the underground temperature is almost constant, which is said to be approximately equal to the annual average temperature at that point. In summer, the daytime air temperature is considerably higher than the ground temperature, and further, air heated by sunlight is passed through the ground, so that the ground temperature can be considerably increased.
