本発明は太陽光を蓄熱して室内の加熱用に用い

A heat storage wall structure (trombe wall) has been proposed in which a wide glass surface is provided on the outside of a stone wall with an air layer in between. With this heat storage wall structure, sunlight is irradiated onto the heat storage wall through the glass surface and the air layer, and heat is stored in the heat storage wall. At night, the heat can be radiated from the heat storage wall into the room to heat the room. It's summery.

の効果が失なわれる不具合を有する。 However, with this wall structure, the heat storage wall heats up even in the summer and has the problem of dissipating heat into the room where cooling is originally required. In communication,
Measures such as releasing heat from heated heat storage walls to the outside have been considered. However, installing an insulating door on the outside of the glass surface only in summer is complicated, and if the air layer is communicated with the outside, the effect of the air layer as an insulating layer that originally prevents heat radiation from the heat storage wall to the outside will be lost. There is a problem with this.
本発明は上記事実を考慮し、冬期には適切に太
陽光を蓄熱して室内を加熱することができ、夏期
には自動的に蓄熱壁の加熱を制限することができ
る蓄熱用壁構造を得ることが目的である。 The present invention takes the above facts into account, and provides a heat storage wall structure that can appropriately store sunlight to heat the room in the winter and automatically limit heating of the heat storage wall in the summer. That is the purpose.
本発明に係る蓄熱用壁構造では、空気層の外側

けて蓄熱効率を向上するようになつている。 In the heat storage wall structure according to the present invention, a Fresnel prism sheet is provided outside the air layer to reflect sunlight in the summer when the angle of incidence of sunlight is large, and to reflect sunlight only in the winter when the angle of incidence is relatively small. In addition, a solar heat absorbing film is attached to the surface of the heat storage wall to improve heat storage efficiency.
以下本発明の実施例を図面に従い説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第１図に示される如く本実施例に係る蓄熱用壁
構造１０は建物の一部に設けられており、室内１
２と室外１４とを仕切る壁部分に用いられてい
る。 As shown in FIG. 1, the heat storage wall structure 10 according to this embodiment is installed in a part of a building, and
It is used for the wall part that partitions the room 2 and the outside 14.
この蓄熱用壁構造１０の室外１４へ面した部分

る。 A Fresnel prism sheet 16 is attached to a portion of this heat storage wall structure 10 facing the outdoors 14, and a heat storage wall 20 is installed inside this Fresnel prism sheet 16 with an air layer 18 in between.
フレネルプリズムシート１６は第２図に示され

小プリズム２２はそれぞれ頂部２４を境に一方が
緩斜面２６、他方が急斜面２８となつている。 As shown in FIG. 2, the Fresnel prism sheet 16 has a plurality of small prism projections 22 formed in a multi-stage shape. These small prisms 22 are located at the top 2
The ridge lines including 4 are perpendicular to the plane of the paper, are parallel to each other, and are spaced at a predetermined interval. Each of these small prisms 22 has a gentle slope 26 on one side and a steep slope 28 on the other side with the top 24 as a boundary.
このフレネルプリズムシート１６はプリズム面

が急斜面２８よりも上方に配置されている。 This Fresnel prism sheet 16 is attached with the prism surface facing outdoors, and the gentle slope 26
is arranged above the steep slope 28.

て蓄熱壁２０方向へ照射することができる。 With this installation, sunlight entering from outside is totally reflected as shown by arrow A when the sun's altitude is high, such as in summer, and direct sunlight entering the heat storage wall 20 can be prevented. Furthermore, in winter when the sun's altitude is low, sunlight can pass through and irradiate in the direction of the heat storage wall 20 as shown by arrow B.
ここで緩斜面２６の頂角θを20度とすれば、日

秋分の正午の太陽の高さを境に区別される（北緯

できる。 Here, if the apex angle θ of the gentle slope 26 is 20 degrees, the reflection and transmission of sunlight are distinguished by the height of the sun at noon on the vernal and autumnal equinoxes, when the elevation angle φ is 55 degrees (northern latitude
35 degree point). This allows most of the summer sunlight to be blocked and only the winter sunlight to enter the room.
空気層１８はその上下が庇３０，３２で閉止さ

陽光を蓄熱壁２０方向へ透過して蓄熱壁２０を加

る。 The air layer 18 is closed at the top and bottom by eaves 30 and 32, and has a sealed structure, so sunlight in winter can pass through toward the heat storage wall 20 and heat the heat storage wall 20. The heat is not allowed to pass toward the Fresnel prism sheet 16.

要がない場合にはこの断熱壁３４は不要である。 The heat storage wall 20 is a thick wall made of concrete, brick, etc., and has a large heat capacity. This heat storage wall 2
A heat insulating wall 34 and wall finishing material 36 are installed inside and outside the room. This heat insulation wall 34 is the heat storage wall 20
A phase difference is provided between the heat generation of the heat storage wall 20 and the heating of the indoor room 12, so that the heat of the heat storage wall 20, which is heated mainly during the day, can be released into the indoor room 12 at night. However, if there is no need to provide a phase difference, this heat insulating wall 34 is unnecessary.
蓄熱壁２０の空気層１８側の表面には太陽熱吸

率（ε）は0.2程度である。 A solar heat absorbing film 38 is attached to the surface of the heat storage wall 20 on the air layer 18 side. This solar heat absorption film is a so-called selective absorption film that has a high heat absorption rate and a low heat emissivity. As an example, a solar heat absorbing film in which black chrome is attached to the surface of an aluminum plate by electroplating etc. can be used, and this solar heat absorbing film has a solar absorption rate (α) of 0.92 or more and a thermal emissivity (ε) of about 0.2. It is.

しかもこの太陽熱吸収膜は施行後の手入れが不要
なため、空気層１８内へ密封できる。 As a result, sunlight passing through the air layer 18 can be absorbed to effectively heat the heat storage wall 20, and the heat retained in the heat storage wall 20 is not released to the air layer 18, improving thermal efficiency. It's summery.
Moreover, since this solar heat absorbing film does not require any maintenance after application, it can be sealed inside the air space 18.

させて蓄熱用壁構造１０を覆うこともできる。 It is also possible to provide an eaves 40 above the heat storage wall structure 10 to protect the Fresnel prism sheet 16 and limit the amount of sunlight irradiated in the summer. The eaves 40 can also be moved to the front of the Fresnel prism sheet 16 to cover the heat storage wall structure 10 when the heat storage wall structure 10 is not in use, as shown by the two-dot chain line.

への放熱を著しく少なくすることができる。 To explain the operation of the heat storage wall structure 10 of this embodiment configured in this way, sunlight passes through the Fresnel prism sheet 16 and irradiates the solar heat absorption film 38, so the solar heat absorption film 38 is heated. , this heat is transferred to the heat storage wall 20 and the heat storage wall 20
It stores heat with a large amount of retained heat. As already mentioned, the Fresnel prism sheet 16 mainly transmits sunlight only in the winter, so the heat storage wall 20 is hardly heated in the summer. Therefore, the air layer 18 can have a sealed structure, and together with the solar heat absorbing film 38, heat radiation from the heat storage wall 20 toward the outside 14 can be significantly reduced.
蓄熱壁２０の保有熱は断熱壁３４を通して所定
時間後に室内１２へ放出されるので、昼間の太陽
光による照射熱を夜間の暖房として用いることが
できる。 Since the heat retained in the heat storage wall 20 is released into the room 12 after a predetermined time through the heat insulating wall 34, the heat irradiated by sunlight during the day can be used for heating at night.

ことができる優れた効果を有する。 As explained above, the heat storage wall structure according to the present invention uses Fresnel prism sheets to select the transmission and reflection of sunlight depending on the altitude of the sunlight, so sunlight can automatically pass through only in winter, and the air layer has an excellent effect of improving the thermal efficiency of the heat storage wall together with the solar heat absorbing film.
