以下、本発明を添付図面に基づいて説明する。   Hereinafter, the present invention will be described with reference to the accompanying drawings.

（第一実施形態）
まず、第一実施形態について説明する。第一実施形態の蓄熱システムでは、図１に示す建物の外壁１に形成された窓２（開口部）に光屈曲手段が設けられ、光屈曲手段を経て屋内の床３に照射された太陽光の熱を床３に設けられた蓄熱材４で吸収する。 (First embodiment)
First, the first embodiment will be described. In the heat storage system of the first embodiment, light bending means is provided in the window 2 (opening) formed in the outer wall 1 of the building shown in FIG. 1, and sunlight irradiated to the indoor floor 3 through the light bending means. The heat is absorbed by the heat storage material 4 provided on the floor 3.

窓２は下端が床３の上面付近に位置して十分な高さを有する矩形状の窓であって、窓２には、透光性を有する窓部材として板状の窓ガラス５が設けられている。なお、窓ガラス５は、単板ガラスであってもよいし、複層ガラスであってもよい。   The window 2 is a rectangular window whose lower end is positioned near the upper surface of the floor 3 and has a sufficient height. The window 2 is provided with a plate-like window glass 5 as a window member having translucency. ing. The window glass 5 may be a single plate glass or a multi-layer glass.

窓ガラス５には、図２に示す熱線制御部６が設けられている。この熱線制御部６は、窓ガラス５の屋外側の面に全体に亘って貼り付けられたフィルム１６に設けられている。フィルム１６はアクリルフィルム又はポリエチレンテレフタレート（ＰＥＴ）フィルムであり、透光性を有している。フィルム１６の表面には屋外側に開口する溝１７が上下方向に複数形成されている。各溝１７の下面は水平であるのに対して、溝１７の上面は屋内側程下方に位置するように傾斜した傾斜面１８となっており、各溝１７の傾斜面１８に熱線制御部６が設けられている。   The window glass 5 is provided with a heat ray control unit 6 shown in FIG. This heat ray control part 6 is provided in the film 16 affixed over the whole surface of the window glass 5 on the outdoor side. The film 16 is an acrylic film or a polyethylene terephthalate (PET) film and has translucency. On the surface of the film 16, a plurality of grooves 17 that open to the outdoor side are formed in the vertical direction. While the lower surface of each groove 17 is horizontal, the upper surface of the groove 17 is an inclined surface 18 that is inclined so as to be located downward on the indoor side. Is provided.

各熱線制御部６は扁平で傾斜面１８と平行であり、上面部を構成する熱線吸収層１４と、下面部を構成する熱線反射層１５で構成されている。熱線吸収層１４は傾斜面１８に塗装によりコーティングされた熱線吸収材で構成され、近赤外又は赤外領域の光を吸収する熱線吸収部をなす。熱線反射層１５は熱線吸収層１４の下面に塗装によりコーティングされた熱線反射材で構成され、近赤外又は赤外領域の光を反射する熱線反射部をなす。   Each heat ray control unit 6 is flat and parallel to the inclined surface 18, and is constituted by a heat ray absorbing layer 14 constituting the upper surface portion and a heat ray reflecting layer 15 constituting the lower surface portion. The heat ray absorbing layer 14 is made of a heat ray absorbing material coated on the inclined surface 18 by painting, and forms a heat ray absorbing portion that absorbs light in the near infrared or infrared region. The heat ray reflective layer 15 is made of a heat ray reflecting material coated on the lower surface of the heat ray absorbing layer 14 by coating, and forms a heat ray reflecting portion that reflects light in the near infrared or infrared region.

屋外側から窓ガラス５に向かう太陽光の進行方向が鉛直下向きに近い場合、当該太陽光はフィルム１６を透過した後に図３中矢印ａ１に示すように熱線吸収層１４に至り、この太陽光に含まれる熱線が熱線吸収層１４で吸収されるようになっている。他方、屋外側から窓ガラス５に向かう太陽光の進行方向が水平方向に近い場合、当該太陽光はフィルム１６を透過せずに溝１７の開口から図３中矢印ｂ１に示すように熱線反射層１５に至る。そして、この太陽光に含まれる熱線は熱線反射層１５で反射してその進行方向が矢印ｂ２に示すように下側、すなわち窓２に近い床３側に傾けられ、フィルム１６及び窓ガラス５を経て屋内の床３に向かう。すなわち、本実施形態では、各熱線制御部６の熱線反射層１５により、屋外から取り込まれる太陽光の進行方向を下側に傾ける光屈曲手段が構成されている。 When the traveling direction of the sunlight toward outdoor side window glass 5 is close to the vertically downward, the sunlight reach the heat absorbing layer 14 as shown in FIG. 3 arrow a 1 after passing through the film 16, the solar The heat rays contained in are absorbed by the heat ray absorbing layer 14. On the other hand, when the traveling direction of sunlight from the outdoor side toward the window glass 5 is close to the horizontal direction, the sunlight does not pass through the film 16 and is reflected by heat rays from the opening of the groove 17 as indicated by an arrow b 1 in FIG. To layer 15. Then, the heat rays contained in the sunlight are reflected by the heat ray reflection layer 15 and the traveling direction thereof is inclined downward, that is, toward the floor 3 side close to the window 2 as shown by the arrow b 2 , and the film 16 and the window glass 5. Go to the floor 3 indoors. That is, in this embodiment, the light-bending means which inclines the advancing direction of the sunlight taken in from the outdoors downward by the heat ray reflective layer 15 of each heat ray control part 6 is comprised.

傾斜面１８、熱線吸収層１４、及び熱線反射層１５の夫々の水平面に対する傾斜角度αは、夏の真昼における太陽高度と冬の真昼における太陽高度の間の角度に設定される。例えば、東京における夏の真昼における太陽高度は７４．４°であり（７月２１日１２時）、冬の真昼における太陽高度は３４．３°（１月２１日１２時）であるため、傾斜角度αは４０°〜６０°の範囲内で設定される。このように傾斜角度αを設定することにより、夏の真昼における直達日射は熱線吸収層１４に至り、冬の真昼における直達日射は熱線反射層１５に至るようになっている。   The inclination angle α of the inclined surface 18, the heat ray absorbing layer 14, and the heat ray reflecting layer 15 with respect to the horizontal plane is set to an angle between the solar altitude at midday in summer and the solar altitude at midday in winter. For example, the solar altitude in Tokyo at midday in summer is 74.4 ° (12:00 on July 21) and the solar altitude in midday in winter is 34.3 ° (12:00 on January 21). The angle α is set within a range of 40 ° to 60 °. By setting the inclination angle α in this way, direct solar radiation at midday in summer reaches the heat ray absorbing layer 14, and direct solar radiation at midday in winter reaches the heat ray reflective layer 15.

蓄熱材４の種類は限定されるものではないが、例えばパラフィン系の潜熱蓄熱材や無機系の蓄熱材が用いられる。なお、蓄熱材４の蓄熱温度は屋内が夏に暑くならず且つ冬に寒くならないように２３℃〜２５℃に設定することが好ましい。   Although the kind of the heat storage material 4 is not limited, for example, a paraffin-based latent heat storage material or an inorganic heat storage material is used. In addition, it is preferable to set the heat storage temperature of the heat storage material 4 to 23 ° C. to 25 ° C. so that the room does not get hot in summer and gets cold in winter.

図１に示すように、蓄熱材４は、床面を構成する床材１９の下面に沿って設けられており、板状に形成されている。蓄熱材４は、前記窓２に設けられた各熱線制御部６の熱線反射層１５で反射した太陽光の床３への照射領域と略重複する又は収まるように窓２の近傍に配置されている。このため、図１に示すように太陽光が各熱線制御部６の熱線反射層１５で反射して床３に照射されると、この太陽光の熱が蓄熱材４に吸収される。そして、このように蓄熱された蓄熱材４は、例えば太陽光熱によって暖められない夜間等に放熱され、この放熱により屋内が暖められる。なお、図１では、窓ガラス５を透過して床３に至る太陽光の上限及び下限の夫々を破線で示しており、太陽光が光屈曲手段を経て屈曲し、この後床３に至る様子を矢印で示している。   As shown in FIG. 1, the heat storage material 4 is provided along the lower surface of the floor material 19 which comprises a floor surface, and is formed in plate shape. The heat storage material 4 is arranged in the vicinity of the window 2 so that it substantially overlaps or falls within the irradiation area of the sunlight reflected on the floor 3 of the heat ray reflecting layer 15 of each heat ray control unit 6 provided in the window 2. Yes. For this reason, as shown in FIG. 1, when sunlight is reflected by the heat ray reflective layer 15 of each heat ray control unit 6 and irradiated onto the floor 3, the heat of the sunlight is absorbed by the heat storage material 4. And the heat storage material 4 stored in this way is radiated at night etc. which are not warmed by solar heat, for example, and indoors are warmed by this heat radiation. In addition, in FIG. 1, each of the upper limit and the lower limit of the sunlight which permeate | transmits the window glass 5 and reaches the floor 3 is shown with the broken line, and the sunlight is bent through the light bending means, and then reaches the floor 3 Is indicated by an arrow.

以上説明した本実施形態の蓄熱システムでは、窓２を介して屋内に取り込まれた太陽光が床３に照射され、この太陽光の熱が床３に設けられた蓄熱材４に蓄えられる。この場合、太陽光により加熱された床３の熱を蓄熱材４に直接吸収することができ、太陽光熱を効率良く利用できる。また、別途ダクトやファンを設ける必要がなく、コストを抑えることができる。   In the heat storage system of this embodiment described above, sunlight taken indoors through the window 2 is irradiated to the floor 3, and the heat of this sunlight is stored in the heat storage material 4 provided on the floor 3. In this case, the heat of the floor 3 heated by sunlight can be directly absorbed by the heat storage material 4, and sunlight heat can be used efficiently. Further, there is no need to provide a separate duct or fan, and costs can be reduced.

また、窓２には屋外から取り込まれる太陽光の進行方向を窓２に近い床３側に傾ける光屈曲手段が設けられ、この光屈曲手段を経て屋内の床３に照射された太陽光の熱が蓄熱材４に蓄えられるようになっている。このため、蓄熱材４を床３の窓側近傍に設けるだけで、太陽光熱を蓄熱できる。   Further, the window 2 is provided with light bending means for tilting the traveling direction of sunlight taken in from the outdoors toward the floor 3 near the window 2, and the heat of sunlight irradiated to the indoor floor 3 through this light bending means. Is stored in the heat storage material 4. For this reason, solar heat can be stored only by providing the heat storage material 4 near the window side of the floor 3.

例えば図６に示す参考例のように窓２から取り込まれる太陽光が屈曲せずにそのまま床３に照射されると、蓄熱材４を窓２から遠く離れた箇所まで広範囲に設ける必要がある。また、この場合、窓２から取り込まれた太陽光が、床３上に配置された家具、ソファー、ラグ等の室内用品によって遮られる可能性があり、床３の蓄熱材４に対応する部分に太陽光が照射されない箇所ができて、蓄熱材４の蓄熱量が減少する恐れがある。しかし、本実施形態では、蓄熱材４を室内用品が配置され難い床３の窓側近傍に設けるだけでよいので、上記の問題を改善できる。すなわち、蓄熱材４を広範囲に設けることなく、十分な蓄熱量を確保できる。   For example, as in the reference example shown in FIG. 6, when the sunlight taken in from the window 2 is irradiated to the floor 3 as it is without being bent, it is necessary to provide the heat storage material 4 in a wide range up to a place far from the window 2. Further, in this case, sunlight taken in from the window 2 may be blocked by furniture such as furniture, sofas, rugs, and other indoor products arranged on the floor 3, and in a portion corresponding to the heat storage material 4 on the floor 3. There may be a place where sunlight is not irradiated, and the heat storage amount of the heat storage material 4 may be reduced. However, in this embodiment, it is only necessary to provide the heat storage material 4 in the vicinity of the window side of the floor 3 where indoor products are difficult to be arranged, so the above problem can be improved. That is, a sufficient amount of heat storage can be secured without providing the heat storage material 4 in a wide range.

図４は、太陽高度が３４．３度（東京 １月２１日１２時）であり、窓２の上下長さＬ１が２．１ｍであるときの、熱線反射層１５の反射面の角度（傾斜角度α）と、床３に照らされた太陽光の窓２から屋内側に伸びる日射面の長さＬ２との関係を表したグラフである。なお、フィルム１６を設けない場合、上記と同条件の下では、床３に照らされた太陽光の日射面の長さＬ３は約３．１ｍとなる。   FIG. 4 shows the angle (inclination) of the reflective surface of the heat ray reflective layer 15 when the solar altitude is 34.3 degrees (Tokyo, January 21, 12:00) and the vertical length L1 of the window 2 is 2.1 m. It is a graph showing the relationship between the angle α) and the length L2 of the solar radiation surface extending indoors from the sunlight window 2 illuminated by the floor 3. In the case where the film 16 is not provided, under the same conditions as described above, the length L3 of the solar radiation surface illuminated by the floor 3 is about 3.1 m.

図４から明らかなように、例えば傾斜角度αを５０°に設定した場合、床３に当たる日射面の長さＬ１は約１ｍとなる。この場合、蓄熱材４はこの日射面の範囲にのみ設ければよく、フィルム１６を設けない場合と比較して蓄熱材４を設ける範囲を大幅に狭めることができる。   As is clear from FIG. 4, for example, when the inclination angle α is set to 50 °, the length L1 of the solar radiation surface that hits the floor 3 is about 1 m. In this case, the heat storage material 4 may be provided only in the range of the solar radiation surface, and the range in which the heat storage material 4 is provided can be significantly narrowed compared to the case where the film 16 is not provided.

また、本実施形態では、図２のように窓２に設けられた熱線制御部６が屋内側に下り傾斜している。このため、進行方向が鉛直方向に近い夏の太陽光は、熱線制御部６の上面を構成する熱線吸収部に当たりやすくなり、進行方向が水平方向に近い冬の太陽光は、熱線制御部６の下面を構成する熱線反射部に当たりやすくなる。従って、夏においては太陽光の熱線を熱線吸収部で吸収して、屋内温度の上昇を抑えることができ、冷房負荷の低減等を実現できる。また、冬季においては太陽光の熱線を熱線反射部で反射して、太陽光熱を蓄熱材４で効率良く吸収することができる。   Moreover, in this embodiment, the heat ray | wire control part 6 provided in the window 2 is inclined down indoors like FIG. For this reason, the sunlight in the summer when the traveling direction is close to the vertical direction is likely to hit the heat ray absorbing portion constituting the upper surface of the heat ray control unit 6, and the sunlight in the winter whose traveling direction is close to the horizontal direction is It becomes easy to hit the heat ray reflective part which comprises a lower surface. Therefore, in summer, the heat ray of sunlight is absorbed by the heat ray absorption unit, and an increase in indoor temperature can be suppressed, and a cooling load can be reduced. Further, in the winter season, the heat rays of sunlight are reflected by the heat ray reflecting portion, and the solar heat can be efficiently absorbed by the heat storage material 4.

なお、本実施形態では、光屈曲手段を窓２に配置された窓ガラス５に設けたが、窓２における窓ガラス５の屋外側や屋内側、窓ガラス５の内部に設ける等してもよい。   In this embodiment, the light bending means is provided on the window glass 5 disposed on the window 2, but it may be provided on the outdoor side or indoor side of the window glass 5 in the window 2, on the inside of the window glass 5, or the like. .

（第二実施形態）
次に第二実施形態について説明する。なお、以下の説明では、第一実施形態と同一の構成については同一の番号を付与し、重複する説明は省略する。 (Second embodiment)
Next, a second embodiment will be described. In the following description, the same components as those in the first embodiment are given the same numbers, and redundant descriptions are omitted.

本実施形態の窓ガラス５には、図５に示すように、フィルム１６に代えてルーバー１１が設けられている。本実施形態の窓ガラス５は、二枚のガラス板７，８を空気層９を介して配置した複層ガラスで構成されている。そして、窓ガラス５の屋外側のガラス板７と屋内側のガラス板８の間にはルーバー１１が設けられており、このルーバー１１に熱線制御部が設けられている。   As shown in FIG. 5, the window glass 5 of the present embodiment is provided with a louver 11 instead of the film 16. The window glass 5 of the present embodiment is composed of a double-glazed glass in which two glass plates 7 and 8 are arranged via an air layer 9. A louver 11 is provided between the glass plate 7 on the outdoor side of the window glass 5 and the glass plate 8 on the indoor side, and the louver 11 is provided with a heat ray control unit.

ルーバー１１は、上下方向に並べて設けられた複数の羽板１２を有しており、各羽板１２が熱線制御部を構成している。各羽板１２は、屋内側に向かって下り傾斜した板状部材１３と、板状部材１３の上面に積層された熱線吸収層１４（熱線吸収部）と、板状部材１３の下面に積層された熱線反射層１５（熱線反射部）とで構成されている。   The louver 11 has a plurality of blades 12 arranged side by side in the vertical direction, and each blade 12 constitutes a heat ray control unit. Each slat 12 is laminated on the plate-like member 13 inclined downward toward the indoor side, the heat ray absorbing layer 14 (heat ray absorbing portion) laminated on the upper surface of the plate-like member 13, and the lower surface of the plate-like member 13. And a heat ray reflective layer 15 (heat ray reflective portion).

板状部材１３は厚さ０．５ｍｍのアルミ板である。熱線吸収層１４は板状部材１３の上面に塗装によりコーティングされた熱線吸収材で構成され、熱線反射層１５は板状部材１３の下面に塗装によりコーティングされた熱線反射材で構成されている。なお、各羽板１２の水平面に対する傾斜角度αは第一実施形態と同じ理由により４０°〜６０°に設定されている。なお、各羽板１２の傾斜角度は手動で変更できるようにしても構わない。   The plate-like member 13 is an aluminum plate having a thickness of 0.5 mm. The heat ray absorbing layer 14 is made of a heat ray absorbing material coated on the upper surface of the plate-like member 13 by coating, and the heat ray reflecting layer 15 is made of a heat ray reflecting material coated on the lower surface of the plate-like member 13 by painting. In addition, the inclination | tilt angle (alpha) with respect to the horizontal surface of each slat 12 is set to 40 degrees-60 degrees for the same reason as 1st embodiment. In addition, you may enable it to change the inclination angle of each slat 12 manually.

屋外側から窓ガラス５に向かう太陽光は屋外側のガラス板７を通ってルーバー１１の羽板１２に至る。この太陽光の進行方向が鉛直下向きに近い場合、当該太陽光は熱線吸収層１４に至り、この太陽光に含まれる熱線が熱線吸収層１４で吸収されるようになっている。他方、太陽光の進行方向が水平方向に近い場合、当該太陽光は熱線反射層１５で反射することでその進行方向が窓２に近い床３側に傾けられ、この後、屋内側のガラス板８を通って屋内の床３に向かう。すなわち、本実施形態では、各羽板１２の熱線反射層１５により光屈曲手段が構成されている。   Sunlight from the outdoor side toward the window glass 5 passes through the glass plate 7 on the outdoor side and reaches the wing plate 12 of the louver 11. When the traveling direction of the sunlight is close to the vertically downward direction, the sunlight reaches the heat ray absorbing layer 14, and the heat rays contained in the sunlight are absorbed by the heat ray absorbing layer 14. On the other hand, when the traveling direction of sunlight is close to the horizontal direction, the sunlight is reflected by the heat ray reflective layer 15 so that the traveling direction is inclined toward the floor 3 near the window 2, and then the indoor side glass plate Go through 8 to the indoor floor 3. That is, in this embodiment, the light bending means is constituted by the heat ray reflective layer 15 of each slat 12.

なお、本実施形態では、熱線制御部を設けたルーバー１１を窓ガラス５の内部に設けたが、窓２における窓ガラス５の屋外側や屋内側に設けても構わない。また、前記各実施形態における光屈曲手段は、太陽光を進行方向が窓２に近い床３側に傾くように反射させるものであるが、光屈曲手段は太陽光を進行方向が窓２に近い床３側に傾くように屈折させるものであってもよい。   In addition, in this embodiment, although the louver 11 which provided the heat ray | wire control part was provided in the inside of the window glass 5, you may provide in the outdoor side of the window glass 5 in the window 2, or an indoor side. Further, the light bending means in each of the embodiments reflects sunlight so that the traveling direction is inclined toward the floor 3 side close to the window 2, but the light bending means has the sunlight traveling direction close to the window 2. You may refract so that it may incline to the floor 3 side.
