Description

本発明は一般に、太陽熱温水器利用システムに関する。より詳細には、本発明は、太陽熱温水器によって得られた熱エネルギーの有効活用を可能にする太陽熱温水器利用システムに関する。   The present invention generally relates to solar water heater utilization systems. In more detail, this invention relates to the solar water heater utilization system which enables the effective utilization of the thermal energy obtained by the solar water heater.

太陽の熱エネルギーを有効に活用する装置として、太陽熱温水器が知られている。太陽熱温水器は一般的に、家屋の屋根に設置した集熱器で太陽エネルギーを取得し、取得した太陽エネルギーで水を加温することによって得られる熱を融雪、暖房、風呂、ロードヒーティング、ビニルハウスなどの種々の用途に活用するものであり、二酸化炭素の排出等のない、環境に優しいエネルギー取得方法であるため、一般家庭においても普及が進んでいる。   Solar water heaters are known as devices that effectively utilize solar thermal energy. Solar water heaters generally acquire solar energy with a collector installed on the roof of a house, and heat obtained by heating water with the acquired solar energy is used for melting snow, heating, bathing, road heating, It is used for various purposes such as vinyl houses, and since it is an environmentally friendly energy acquisition method that does not emit carbon dioxide, it is also spreading in general households.

しかしながら、太陽熱温水器は、日照時間の影響を受けるという特性を有している。すなわち、夏季などのように日照時間が長い季節においては、熱エネルギーの吸収量が多くなって消費しきれなくなる一方、冬季などのように日照時間が短い季節においては、熱エネルギーの吸収量が少なくなって必要量に足りないという事態が生ずる。したがって、太陽熱温水器によって得られる熱エネルギーを季節差に影響されずに有効に活用することができるシステムに対する強い要請がある。   However, solar water heaters have the property of being affected by sunshine hours. In other words, in summer seasons and other periods where sunshine hours are long, the amount of heat energy absorbed increases and cannot be consumed. The situation where it becomes insufficient is necessary. Therefore, there is a strong demand for a system that can effectively use the thermal energy obtained by the solar water heater without being affected by the seasonal difference.

本発明は、このような状況に鑑みて開発されたものであって、太陽熱温水器によって得られた熱エネルギーを有効に活用することができる太陽熱温水器利用システムを提供することを目的としている。   This invention is developed in view of such a condition, Comprising: It aims at providing the solar water heater utilization system which can utilize the thermal energy obtained by the solar water heater effectively.

本願請求項1に記載の太陽熱温水器利用システムは、集熱部および貯湯槽を有する太陽熱温水器と、地中に埋設される蓄熱配管と、前記太陽熱温水器の貯湯槽と前記蓄熱配管とを連結し、加温された液体を前記蓄熱配管に供給するための第1配管と、前記太陽熱温水器の貯湯槽と前記蓄熱配管とを連結し、地中において放熱した液体を前記太陽熱温水器の貯湯槽に戻すための第2配管とを備えていることを特徴とするものである。   The solar water heater utilization system according to claim 1 of the present application includes a solar water heater having a heat collecting part and a hot water storage tank, a heat storage pipe buried in the ground, a hot water storage tank of the solar water heater, and the heat storage pipe. The first pipe for connecting and heating the heated liquid to the heat storage pipe, the hot water storage tank of the solar water heater and the heat storage pipe are connected, and the liquid radiated in the ground is discharged from the solar water heater. And a second pipe for returning to the hot water tank.

本発明の太陽熱温水器利用システムによれば、夏季などのように日照時間が長い季節において取得した熱エネルギーを地中の蓄熱層に蓄積しておき、冬季などのように日照時間が短い季節に所望の用途(例えば、融雪、暖房、風呂、生活水、ロードヒーティング、ビニルハウスなど)に活用するものであり、二酸化炭素の排出等のに使用することができるので、太陽熱温水器によって得られた熱エネルギーを有効に活用することが可能になる。本システムは、土を蓄熱媒体としているため、低コストで製造することができる。また、本システムは、構造が簡単であるため、製造コストが廉価であり、故障が少なく、維持管理も低コストで行うことができる。   According to the solar water heater utilization system of the present invention, the thermal energy acquired in a season with a long sunshine time such as in the summer is accumulated in the underground heat storage layer, and in a season with a short sunshine time such as in the winter. It can be used for desired applications (for example, snow melting, heating, bathing, domestic water, road heating, vinyl house, etc.), and can be used for carbon dioxide emission, etc., so it can be obtained by a solar water heater. It is possible to effectively use the thermal energy. Since this system uses soil as a heat storage medium, it can be manufactured at low cost. In addition, since this system has a simple structure, the manufacturing cost is low, there are few failures, and maintenance can be performed at a low cost.

次に図面を参照して、本発明の好ましい実施の形態に係る太陽熱温水器利用システムについて詳細に説明する。図1は、本発明の好ましい実施の形態に係る太陽熱温水器利用システムの全体を模式的に示した図である。図1において全体として参照符号10で示される本発明の好ましい実施の形態に係る太陽熱温水器利用システムは、太陽熱温水器12を備えている。   Next, with reference to drawings, the solar water heater utilization system which concerns on preferable embodiment of this invention is demonstrated in detail.

In FIG. 2, reference numerals 12a1, 12a2, and 12a3 respectively indicate a first header channel, a second header channel, and a joint channel that connects the first header channel and the second header channel. Reference numerals 12a4 and 12a5 denote connection channels that connect the first header channel 12a1 and the hot water tank 12b, and connection channels that connect the second header channel 12a2 and the hot water tank 12b. The heat collecting part 12a is housed in a case 12c whose surface is formed of a light transmissive material.

太陽熱温水器利用システム10は又、地中に埋設される蓄熱配管14を備えている。蓄熱配管14は、太陽熱温水器によって得られた熱エネルギーを地中の蓄熱層に伝達するための配管である。蓄熱配管14は、熱エネルギーを蓄熱層に伝達するため、出来るだけ長い距離、蓄熱層内に位置するように配置されている。蓄熱配管14を設置する孔は、杭打ち機によって穿孔されたものを用いる。これにより、蓄熱配管14の設置コストを低減することができる。   The solar water heater utilization system 10 also includes a heat storage pipe 14 embedded in the ground. The heat storage pipe 14 is a pipe for transmitting the thermal energy obtained by the solar water heater to the underground heat storage layer. The heat storage pipe 14 is disposed so as to be located in the heat storage layer as long as possible in order to transmit heat energy to the heat storage layer. As the hole for installing the heat storage pipe 14, a hole drilled by a pile driving machine is used. Thereby, the installation cost of the heat storage piping 14 can be reduced.

図3は、太陽熱温水器利用システム10の別の形態を示した模式図である。図3に示される太陽熱温水器利用システム10では、地中に蓄熱用の孔を穿孔し、この蓄熱孔内に蓄熱配管14が配置されている点を除いて、図1に示される太陽熱温水器利用システム10と実質的に同一の構成を有している。   FIG. 3 is a schematic diagram showing another form of the solar water heater usage system 10. In the solar water heater utilization system 10 shown in FIG. 3, the solar water heater shown in FIG. 1 is provided except that a hole for heat storage is drilled in the ground, and the heat storage pipe 14 is disposed in the heat storage hole. The usage system 10 has substantially the same configuration.

蓄熱層への熱エネルギーの放出を効率的に行うため、蓄熱配管14として、一対のパイプを並置した“U”字形管を用いてもよいし(図4(a)参照)、蓄熱配管14に、放熱片14a(図4(b)にフィン状の放熱片14a、図4(c)に鍔状の放熱片14aが図示されている)を設けてもよい。なお、図4に示された形態は一例にすぎず、蓄熱配管14の外表面積を増大して蓄熱層への熱エネルギーの伝達を効率的に行うことができるものであれば、他の形態のものを使用してよい。   In order to efficiently release the heat energy to the heat storage layer, a “U” -shaped pipe in which a pair of pipes are juxtaposed may be used as the heat storage pipe 14 (see FIG. 4A). Further, a heat radiating piece 14a (a fin-shaped heat radiating piece 14a is shown in FIG. 4B and a bowl-shaped heat radiating piece 14a is shown in FIG. 4C) may be provided. Note that the form shown in FIG. 4 is merely an example, and any other form can be used as long as it can efficiently transfer the heat energy to the heat storage layer by increasing the outer surface area of the heat storage pipe 14. You may use things.

太陽熱温水器利用システム10は更に、太陽熱温水器12の貯湯槽12bと蓄熱配管14とを連結し、温水を蓄熱配管14に供給する第1配管16と、太陽熱温水器12の貯湯槽12bと蓄熱配管14とを連結し、蓄熱層において放熱した水を太陽熱温水器12に戻すための第2配管18とを備えている。なお、第1配管16と第2配管18には、開閉用の弁16a、18a、18bがそれぞれ設けられている。また、第2配管18には、水を強制的に循環させるため、ポンプが設けられている。   The solar water heater utilization system 10 further connects the hot water storage tank 12b of the solar water heater 12 and the heat storage pipe 14, and supplies the hot water to the heat storage pipe 14, the first pipe 16 and the hot water tank 12b of the solar water heater 12 and the heat storage. The pipe 14 is connected, and the second pipe 18 for returning the water radiated in the heat storage layer to the solar water heater 12 is provided. The first pipe 16 and the second pipe 18 are provided with opening / closing valves 16a, 18a, and 18b, respectively. The second pipe 18 is provided with a pump for forcibly circulating water.

以上のように構成された太陽熱温水器利用システム10の作動について説明する。太陽熱温水器12によって加温された温水が、第1配管16を介して蓄熱配管14に供給される。蓄熱配管14に供給された温水の熱エネルギーは、土を媒体として、地中の蓄熱層に伝達されて蓄えられる。熱エネルギーを蓄熱層に伝達して温度が低下した水は、第2配管18を介して太陽熱温水器12に戻され、太陽熱を取得して再び加温される。以上の工程を繰り返すことにより、夏季などのように日照時間の長い季節に、蓄熱層に熱エネルギーを蓄え、このようにして蓄えられた熱エネルギーを、冬季などのように日照時間の短い季節に、所望の用途(例えば、冬季の室内暖房や生活水、道路や駐車場のロードヒーティング、ビニルハウス、融雪など)に使用する。   Operation | movement of the solar water heater utilization system 10 comprised as mentioned above is demonstrated. Hot water heated by the solar water heater 12 is supplied to the heat storage pipe 14 via the first pipe 16. The thermal energy of the hot water supplied to the heat storage pipe 14 is transmitted to and stored in the underground heat storage layer using soil as a medium. The water whose temperature has decreased due to the transfer of thermal energy to the heat storage layer is returned to the solar water heater 12 via the second pipe 18, acquires solar heat, and is heated again. By repeating the above process, heat energy is stored in the heat storage layer in seasons with long sunshine hours, such as in summer, and the heat energy thus stored is stored in seasons with short sunshine hours, such as in winter. , Used for desired applications (for example, indoor heating and living water in winter, road heating of roads and parking lots, vinyl houses, snow melting, etc.).

18,647MJ / unit ÷ 105MJ / m 3 = 196m 3 / unit, assuming that the solar water heater's thermal efficiency is 60%
196m 3 / unit x 60% ÷ 365 days = 0.322m 3 / day / unit.
