The present invention according to claim 4 provides the method according to claim 3,

It is a non-powered heat storage structure of a solar building that is configured so that an air flow flows around the outer periphery of the light guide duct.

建屋の下方に延びる第２ダクトが偏平であるため、壁面等に沿った偏平な空間を利用してコンパクトに光束を建屋下部に導き、光エネルギーを蓄熱槽に蓄熱できる。しかも、これに動力エネルギーを必要としない。そして比較的容量の大きな蓄熱槽を建屋下部に配置し、耐震性の強い太陽光の建屋の無動力蓄熱構造を提供できる。
第２ダクトの下端の受熱体が蓄熱槽と蓄熱媒体を介して接続するので、蓄熱槽内部に高温部を容易に形成できる。そのため、その高温部から熱エネルギーを効率よく取り出すことができる。また、受熱体は止水機能を有するので、熱媒体がダクト内に流入することを防止し、内面に光反射面を有する金属製のダクト内部の温度上昇や熱媒体の蒸発を抑制できる。
さらに偏平な光束に集光するリニアフレネルレンズは、非結像型であるので、結像に伴う内面に光反射面を有する金属製の導光ダクト内に部分的加熱が生じることを防止し、安全な太陽光の建屋の無動力蓄熱構造を提供できる。 Since the second duct extending downward from the building is flat, the light beam can be compactly guided to the lower part of the building using a flat space along the wall surface or the like, and light energy can be stored in the heat storage tank. Moreover, it does not require motive energy. A heat storage tank having a relatively large capacity can be arranged in the lower part of the building to provide a non-powered heat storage structure of a solar building with strong earthquake resistance.
Since the heat receiving body at the lower end of the second duct is connected to the heat storage tank via the heat storage medium, the high temperature part can be easily formed inside the heat storage tank. Therefore, heat energy can be efficiently extracted from the high temperature part. Moreover, since the heat receiving body has a water stopping function, the heat medium can be prevented from flowing into the duct, and the temperature rise inside the metal duct having the light reflecting surface on the inner surface and the evaporation of the heat medium can be suppressed.
Furthermore, since the linear Fresnel lens that focuses light into a flat light beam is a non-imaging type, it prevents partial heating from occurring in a metal light guide duct having a light reflecting surface on the inner surface accompanying imaging, It is possible to provide a non-powered heat storage structure for safe solar buildings.

この蓄熱槽６内には、水等の蓄熱媒体が収納されている。そしてこの蓄熱槽６にヒートパイプ17を介し熱交換器18が連結され、その熱交換器18により給湯又は暖気が室内に供給される。この過程においても動力エネルギーは必要としない。 Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 and FIG. 2 show the zero-gravity heat storage structure of a solar building of the present invention. In this example, a non-imaging type linear Fresnel lens 1 is arranged at the lower part of the roof 10 of the building 9 and is horizontal on the output side. One end of the first light guide duct 2 is disposed, and a second light guide duct 4 is provided below the other end of the first light guide duct 2 so as to be orthogonal to the first light guide duct 2. A mirror 3 is arranged at the corner of the optical duct 4. And the heat receiving body 5 is provided in the lower end of the 2nd light guide duct 4, The heat receiving body 5 is connected with the heat storage tank 6 (long-term heat storage tank).
A heat storage medium such as water is accommodated in the heat storage tank 6. A heat exchanger 18 is connected to the heat storage tank 6 via a heat pipe 17, and hot water or warm air is supplied into the room by the heat exchanger 18. No power energy is required in this process.
