本発明は地中蓄熱装置に関し、特に地中に設置
される熱交換器の設置構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underground heat storage device, and particularly to an installation structure for a heat exchanger installed underground.
近年、太陽熱等を回収して熱媒体を介して地中
に蓄熱し、該蓄熱された熱を適時利用する地中蓄
熱装置の一般家庭用としての実用化が検討されて
いるが、地中に熱媒体が通流する熱交換器を設置
する場合に種々の問題点があつた。 In recent years, the practical application of underground thermal storage devices for general household use, which collects solar heat, stores it underground via a heat medium, and uses the stored heat in a timely manner, has been considered. Various problems have arisen when installing a heat exchanger through which a heat medium flows.
即ち、従来の一般的な工法によれば、床下にあ
たる地面を適当な深さ例えば1.5〜2m（深く配管

しく工事費が嵩む。また、配管後の埋め戻し作業
後、土の圧着沈下が発生し、掘削した面上への家
屋の建設が可能になるまで時間を要す。 That is, according to the conventional general construction method, the ground beneath the floor is excavated to an appropriate depth, for example, 1.5 to 2 m (the deeper the piping, the greater the heat storage amount and heat storage period), and the heat exchanger is installed there. After the pipes are laid in a meandering manner, they are backfilled with soil, but this construction method requires a large amount of soil to be moved, which increases construction costs. Furthermore, after backfilling after piping, the soil presses and settles, and it takes time until it is possible to construct a house on the excavated surface.
そこで特開昭50−161049号公報に示されるよう

向に挿入して設置するようにしたものがある。 Therefore, as shown in Japanese Patent Application Laid-open No. 50-161049, a heat exchanger for underground heat storage is a straight pipe with a double structure, with an inner cylinder on the heat medium sending side and an outer cylinder on the heat medium return side. Formed as a heat exchange pipe by a shaped member,
Some heat exchange pipes are installed by inserting a large number of these heat exchange pipes into the ground in the direction of its depth.

ていたため、施工面積を更に小さくして、土地を
有効利用する点などから見ると尚改善の余地があ

に集中させることができないものであつた。 However, in this system, a large number of heat exchange pipes were all placed in parallel and inserted vertically, so there is still room for improvement in terms of further reducing the construction area and making effective use of the land. Moreover, it was not possible to efficiently concentrate the piping between the heat exchange pipes in one place.

Connect the heat medium inlet at the upper end of the heat exchange pipe, and connect the heat medium outlet at the upper end to the heat medium inlet at the upper end of the group of heat exchange pipes on the inner circle side through a gear. The heat medium outlet part of the upper end of the heat exchange pipe group on the side is connected to the heat medium inlet part of the upper end of the heat exchange pipe group on the outer circle side through a gear, and the upper end of the heat exchange pipe group on the outer circle side The heat medium outlet portion of the heat medium is connected to the heat medium return pipe via a gear.

Therefore, in summer and autumn, the air in the air layer 1 is heated, and the heat is removed by the evaporator 3, radiated by the condenser 4, and transferred to the heat medium via the heat exchanger 5. The heat of this heat medium can be used directly and is also stored underground through a heat exchange pipe 6 inserted underground under the floor. In addition, heat pump 2 is installed in winter and spring.
The amount of heat transferred to the heat medium through the heat exchanger 5 decreases, but the shortage is made up by the heat stored in the ground being released through the heat exchange pipe 6. Heat is available.

As described above, the heat medium supply pipe 21 from the heat exchanger 5 is inserted into the ground in a multiple conical radial shape, as shown in FIG. It is connected to the inlet part 14 of the heat exchange pipe 6-1, and its outlet part 15 is connected to the annular gear gallery 23 via the communication pipe 22. Then, this gear rally 23 is connected to each inlet portion 14 of the heat exchange pipe 6-2 group through a communication pipe 24, and each of the outlet portions 15 of the heat exchange pipe 6-2 group is connected to the
is connected to an annular gear 26 via a connecting pipe 25. This gear assembly 26 is connected to each inlet section 14 of the heat exchange pipe 6-3 group through a communication pipe 27, and each outlet section 15 thereof is connected to an annular gear assembly 29 via a communication pipe 28. A heat medium return pipe 30 is connected to this gear gallery 29 and connected to the heat exchanger 5 via the pump 8. Therefore, the header 7 is connected to the heat medium supply pipe 2.
1, communication pipes 22, 24, 25, 27, 28, gears 23, 26, 29, and a heat medium return pipe 30. Incidentally, a heat insulating material 31 is laid on the ground surface as necessary.

可能である。 Thus, by the action of the pump 8 interposed in the middle of the heat medium return pipe 30, the heat medium (for example, brine mixed with antifreeze) from the heat exchanger 5 is transferred from the heat medium supply pipe 21 to the central heat exchange pipe. 6-
1, flows to the heat exchange pipe 6-2 group via the communication pipe 22, geararry 23, and communication pipe 24, and further flows to the heat exchange pipe 6-3 group via the communication pipe 25, geararry 26, and communication pipe 27. . Further, the heat medium return pipe 30 passes through the communication pipe 28 and the gear gallery 29.
It is then returned to the heat exchanger 5. Note that this heat medium can be taken out from the middle of the heat medium supply pipe 21 and used.

ても済む。 In each heat exchange pipe 6, the heat medium is at the inlet 1
4, flows down the flow path in the inner cylinder 11 made of a heat insulating material, is released into the outer cylinder 12 from the opening at the lower end, and is formed between the outer cylinder 12 and the inner cylinder 11. Rise up the road. During this rising process, the heat medium exchanges heat with the surrounding soil through the outer cylinder 12, that is, the heat of the heat medium is given to the soil to store heat, or the stored heat is absorbed by the heat medium and flows out from the outlet. do.
Here, the cross-sectional area of the flow path formed between the outer cylinder 12 and the inner cylinder 11 is sufficiently larger than the cross-sectional area of the flow path within the inner cylinder 11, and the flow path between the outer cylinder 12 and the inner cylinder 11 is Since the flow rate of the heating medium is significantly reduced, the heat transfer time is increased and the heat exchange efficiency is improved.
Further, since heat exchange is performed through the outer cylinder 12 having a large surface area, the heat transfer area is also large, which also improves the heat exchange efficiency. Note that the cross-sectional shape of the outer cylinder 12 is not limited to a circular shape, but may be polygonal, star-shaped, or the like to further increase the heat transfer area. Therefore, the heat exchange pipe 6 does not need to be very long.

果も得られる。 As explained above, according to the present invention, the heat exchanger for underground heat storage is formed as a straight heat exchange pipe and is inserted into the ground in the depth direction, so it can be easily constructed. In addition to being able to reduce construction costs and avoid destroying the ground that the foundation materials of houses and other buildings are in contact with, it is also possible to arrange a large number of heat exchange pipes in a conical radial shape with the apex near the upper end. As a result, the construction area is small, land can be used effectively, and workability is improved when using an earth drill. Moreover, the effect that the piping (header) between the heat exchange pipes can be concentrated in one place can also be obtained.

ど蓄熱されにくくなつてしまうからである。 Further, since a large number of heat exchange pipes are arranged on a plurality of cone generating lines, heat can be stored in a well-balanced manner in terms of heat distribution within the area surrounded by the outer circle. That is, in a single circle, heat can be stored only around the pipe, and the larger the circle is, the harder it is to store heat in the enclosed center.

（温・冷熱共）ができる。 Furthermore, since the heat medium is made to flow through the central heat exchange pipe and then from the inner circle side to the outer circle side heat exchange pipes, it is possible to connect underground with multiple heat exchange pipes in one circulation. As heat is exchanged, the amount of heat stored on the outer ring side is such that the temperature difference with other underground parts is not significantly large, and therefore the heat diffusion (dissipation) rate can be lowered, making it more effective. It can store heat (both hot and cold).
