【発明の詳細な説明】
本発明は、太陽熱や工場排熱等の熱を土中に蓄
熱し、必要に応じて回収する土中蓄熱装置の改良
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an underground heat storage device that stores heat such as solar heat and factory exhaust heat in the soil and recovers it as necessary.
この種の蓄熱装置は温水管または温風導管（ダ
クト）を土中に埋設し、これらの管を介して熱媒
と土との熱交換させるものである。 This type of heat storage device has hot water pipes or hot air pipes (ducts) buried in the soil, and heat is exchanged between the heat medium and the soil via these pipes.
ところが、この導管は、完全不透水性の材料
（主に鋼管）であるので、土が加熱されると乾燥
し熱伝導が悪化する。これを防ぐ目的で温水を土
に注入することは細菌、重金属等による汚染の恐
れがあるため法律で禁じられてできない。つま
り、適当な対策がなかつたのである。 However, since these conduits are made of completely impermeable material (mainly steel pipes), when the soil is heated, it dries and heat conduction deteriorates. Injecting hot water into the soil for the purpose of preventing this is prohibited by law and cannot be done due to the risk of contamination with bacteria, heavy metals, etc. In other words, there was no appropriate countermeasure.
本発明は、この点を改良するものであり、導管
中の水分の一部を水蒸気の状態で土中に供給して
土の乾燥を防ぎ、もつて熱伝導の低下を防ぐもの
である。 The present invention improves this point by supplying a portion of the moisture in the conduit into the soil in the form of steam to prevent the soil from drying out, thereby preventing a decrease in heat conduction.
以下、図面を参照して説明する。 This will be explained below with reference to the drawings.
第１図は本発明装置の全体を示す略図であつ
て、温水槽１内の温水はポンプ２により地中の導
管３を流れて、土中で熱交換されて再び温水槽に
戻る。 FIG. 1 is a schematic diagram showing the entire apparatus of the present invention, in which hot water in a hot water tank 1 flows through an underground conduit 3 by a pump 2, undergoes heat exchange in the soil, and returns to the hot water tank again.
この導管３の管壁の一部は、完全不透水性でな
く、複数個の水分子が凝集したもの（通常の水）
は通過しないが、分子状の水すなわち水蒸気は通
過するいわゆる透湿防水性の材料４で置換されて
いる。 A part of the pipe wall of this conduit 3 is not completely water-impermeable, but is made up of aggregation of multiple water molecules (normal water)
is replaced by a so-called moisture-permeable and waterproof material 4, which does not pass through, but allows molecular water, ie water vapor, to pass through.
この透湿防水性材料としては例えばポバールが
あるが、強度が不足して、独立して導管とするこ
とは現状では困難である。そこで第２図に示すよ
うに、従来の剛性導管（鋼管等）に孔３′をあけ、
その部分に透湿防水性の膜４′を貼り付けたり、
第３図に示すように、導管の一部の全断面を補強
筋５により補強された透湿防水性の材料からなる
管４″に置換、接続するなどして行う。 Poval is an example of this moisture-permeable and waterproof material, but it is currently difficult to use as an independent conduit due to insufficient strength. Therefore, as shown in Figure 2, a hole 3' is made in a conventional rigid conduit (steel pipe, etc.).
Paste a moisture-permeable waterproof membrane 4' on that part,
As shown in FIG. 3, the entire cross section of a part of the conduit is replaced and connected to a tube 4'' made of a moisture-permeable and waterproof material reinforced with reinforcing bars 5.
さて、この装置を運転すると、循環中の熱媒中
に含まれる水蒸気は、透湿防水槽を徐々に透過
し、土を湿潤に保つ。その際、細菌、重金属等を
伴なわないから土を汚染することがない。 Now, when this device is operated, the water vapor contained in the circulating heating medium gradually permeates through the moisture-permeable waterproof tank, keeping the soil moist. At that time, it does not contaminate the soil because it does not involve bacteria, heavy metals, etc.
なお、図面には記載しないが、熱媒体が温風で
あつても差支えなく、その場合には、加湿、負圧
付与等により水蒸気自体を熱媒として加担させる
ことも可能である。 Although not shown in the drawings, there is no problem even if the heating medium is hot air, and in that case, it is also possible to use water vapor itself as a heating medium by humidifying, applying negative pressure, etc.
さらに特殊な溶液を温度と水蒸気圧力の関係を
変えて効果を増加させることもできる。 Furthermore, the effectiveness of special solutions can be increased by changing the relationship between temperature and water vapor pressure.
以上、本発明は、土中の導管の一部を透湿防水
材とするものであるから土を汚染せず湿潤にし、
熱伝導を良好にする利点を有する。 As described above, the present invention uses a moisture-permeable waterproof material for a part of the conduit in the soil, so it keeps the soil moist without contaminating it.
It has the advantage of improving heat conduction.
そして、導管の一部に孔をあけ、その部分に透
湿防水性の膜を貼る構造としたときは、その周囲
の土を均等に加湿し、効率的である利点を有す
る。 When a hole is made in a part of the conduit and a moisture-permeable waterproof membrane is applied to the hole, the soil around the hole is evenly humidified, which has the advantage of being efficient.
