　従来より、例えば床下空間内に多数のグリ石を充填させることにより床下空間内蓄熱層を形成しておき、戸外からの空気を前記床下空間内蓄熱層内に導入して熱交換させ、さらにこの熱交換された空気を、地盤面から例えば約５～８ｍ（又は２～１０ｍ）の地中に埋設した地中パイプ中で流通させながら地中熱と熱交換させ、この熱交換された空気を建物の室内や床下空間に供給するようにした、建物内換気システムが知られている（特許文献１，２参照）。なお、特許文献１，２において使用されている前記地中パイプは、例えば、下端部が閉塞された外管と、外管の内部に配置され下端部が開放された内管とから成り、戸外から導入した空気を外管と内管との間の隙間内で下降させた後、外管の底部に衝突させ反転させた後に内管の内部に移動させて上昇させる二重パイプで、前記空気を前記下降、衝突及び反転などの過程で地中熱と熱交換させるものである。 Conventionally, for example, an underfloor space heat storage layer is formed by, for example, filling a large number of grits in the underfloor space, air from the outside is introduced into the underfloor space heat storage layer, and heat exchange is performed. The heat-exchanged air is exchanged with the underground heat while circulating in the underground pipe buried in the ground, for example, about 5 to 8 m (or 2 to 10 m) from the ground surface. There is known a ventilation system in a building that is supplied to a room or an under-floor space of a building (see Patent Documents 1 and 2). The underground pipe used in Patent Documents 1 and 2 is composed of, for example, an outer pipe whose lower end is closed and an inner pipe which is disposed inside the outer pipe and whose lower end is opened. A double pipe that lowers the air introduced from the outer pipe and the inner pipe, then collides with the bottom of the outer pipe, inverts it, moves it to the inside of the inner pipe, and raises it. Is exchanged with underground heat in the process of descending, colliding and reversing.

　しかしながら、既築の建物の床下にグリ石を入れることは実際上極めて困難であることから、特許文献１，２に示すような床下空間内蓄熱層は、事実上、新築の建物にしか設置することができない。そのため、従来は、既築の建物に対しては、地中熱及び蓄熱層を利用した建物内換気システムを低コストで効率よく設置（追加）することが、できなかった。 However, since it is actually very difficult to put guristone under the floor of an existing building, the heat storage layer in the underfloor space as shown in Patent Documents 1 and 2 is actually installed only in a new building. I can't. For this reason, conventionally, it has not been possible to efficiently install (add) a building ventilation system using underground heat and a heat storage layer at low cost for an existing building.

Air can flow through the middle pipe and the gaps between each of the heat storage bodies provided in the interior, and each of the heat storage bodies and the heat are circulated in the interior of the outside air taken in from the outside. An outside air circulation heat storage layer to be exchanged, the outside air circulation heat storage layer connected to the underground pipe so as to be able to distribute the air, and outside air from the outside is taken in, and the taken-in outside air is taken into the outside air circulation heat storage layer and the underground A ventilation fan that circulates inside the pipe and then supplies it to the interior of the building, and the outdoor air circulation heat storage layer is an area on the floor surface that is close to the outer wall surface inside the building and extends along the outer wall surface. In which a number of regenerator in the partition space extending upward is formed by being accommodated from elongated in area on the floor surface Te.
　また、本発明による外壁側外気流通蓄熱層を備えた建物内換気システムにおいては、前記各蓄熱体が収容される仕切り空間は少なくともその一つの面が外壁面により画されていてもよい。 In the building ventilation system provided with the outer wall side outdoor air circulation heat storage layer according to the present invention, at least one surface of the partition space in which each heat storage body is accommodated may be defined by the outer wall surface.
　さらに、本発明による外壁側外気流通蓄熱層を備えた建物内換気システムにおいては、前記各蓄熱体が収容される仕切り空間は略箱状容器により外部と仕切られていてもよい。 Furthermore, in the building ventilation system provided with the outer wall side outdoor air circulation heat storage layer according to the present invention, the partition space in which each heat storage body is accommodated may be partitioned from the outside by a substantially box-shaped container.
　本発明においては、前記地中パイプと空気流通可能に接続された蓄熱層、前記地中パイプからの空気を自らの内部に導入した後に室内又は床下空間に供給する蓄熱層、又は戸外からの空気を自らの内部に導入した後に前記地中パイプに供給する蓄熱層を、地盤面又は床面における外壁と隣接する領域（外壁の外側又は内側の領域）から上方向（縦方向）に突出するように形成された空間内に、多数のグリ石その他の蓄熱体を収容することにより形成している。このように、本発明では、前記蓄熱層を建物の床下空間を使用しないで構成するようにしたので、前記蓄熱層を、既築の建物に対しても、低コストで且つ容易に付加できるようになる。よって、本発明によれば、地中熱及び蓄熱層を利用した建物内換気システムを、既築の建物に対しても、低コストで且つ効率よく設置（追加）できるようになる。 In the present invention, the heat storage layer connected to the underground pipe so as to be able to flow air, the heat storage layer that supplies air from the underground pipe to the interior or the underfloor space after the air is introduced into itself, or the air from the outdoors The heat storage layer to be supplied to the underground pipe after being introduced into the inside thereof protrudes upward (vertically) from a region adjacent to the outer wall on the ground surface or floor surface (region outside or inside the outer wall). It is formed by accommodating a large number of grits and other heat accumulators in the space formed.

An underground pipe (for example, a double pipe comprising an outer pipe 5a having a diameter of about 30 to 50 cm and an inner pipe 5b having a diameter of about 15 to 40 cm), 6 is used to take in outdoor air from the suction port 6a. An air supply chamber to be supplied to the pipe 5 (the air in the air supply chamber 6 is introduced and lowered into the gap between the outer pipe 5a and the inner pipe 5b of the underground pipe by a fan not shown), 7 Is a partition plate (to be fixed to the outer wall 1 or the floor surface 3) that forms a substantially rectangular parallelepiped space projecting upward (vertically) from the floor surface 3 on the indoor side of the outer wall 1. , 7a on the illustration of the partition plate 7 A blower outlet formed in a portion, which discharges air in the space to the indoor side, and 5ba is introduced into the lower position in the space formed by the partition plate 7 and the outer wall 1.

A circulation duct (for winter) 11 connected to the inside is a damper opened to send warm air near the lower side of the roof 2 to the air supply chamber 6 through the circulation duct 10 in winter. .
　図１Ｃに示すように、前記仕切板７は、平断面が略コの字状の板などにより構成されている。また、図１Ｃに示すように、前記蓄熱層８は、前記仕切板７と外壁１（図１Ａの例では外壁の室内側の面）と床面３とで囲まれ区画された収容空間１４内に、多数のグリ石１３を充填することにより構成されている。前記収容空間１４内では前記各グリ石１３間の各隙間を介して互いに空気が流通できるようになっている。前記蓄熱層８は、前記地中パイプ５内で地中熱と熱交換された空気を取り込み、その空気の熱を前記各グリ石１３に伝え蓄熱させると共に前記空気を前記各グリ石１３と熱交換させた後、前記熱交換された空気を前記吹出口７ａから室内に放出、供給するものである。なお、図１Ｃにおいて、７ｂは前記収容空間１４の上方を塞ぐための薄板状の蓋部である。 As shown in FIG. 1C, the partition plate 7 is constituted by a plate having a substantially U-shaped flat cross section. Further, as shown in FIG. 1C, the heat storage layer 8 is contained in an accommodation space 14 surrounded and partitioned by the partition plate 7, the outer wall 1 (inner surface of the outer wall in the example of FIG. 1A), and the floor surface 3. In addition, a large number of grits 13 are filled. In the housing space 14, air can flow through each gap between the grits 13. The heat storage layer 8 takes in the air heat-exchanged with the underground heat in the underground pipe 5, transfers the heat of the air to each of the stones 13, and stores the heat with each of the stones 13. After the replacement, the heat-exchanged air is discharged and supplied into the room from the air outlet 7a. In FIG. 1C, reference numeral 7b denotes a thin plate-like lid portion for closing the upper portion of the accommodation space 14.
　次に本実施形態１の動作を説明する。図示しないファンが常時作動されることにより、夏季の戸外の暑い空気（又は冬季の戸外の冷たい空気）は、前記空気供給室６内に導入された後、前記地中パイプ５の外管５ａと内管５ｂとの間の隙間内に導入され、そこを下降し、外管５ａの底部５ａａに衝突し、反転して内管５ｂ内に入り、上昇する。これらの過程で、前記夏季の戸外の暑い空気（又は冬季の戸外の冷たい空気）は、夏季は外気よりも冷たい地中熱（又は冬季は外気よりも暖かい地中熱）と熱交換される。 Next, the operation of the first embodiment will be described. When a fan (not shown) is always operated, hot outdoor air in summer (or cold outdoor air in winter) is introduced into the air supply chamber 6 and then the outer pipe 5a of the underground pipe 5 and It is introduced into the gap between the inner pipe 5b, descends there, collides with the bottom 5aa of the outer pipe 5a, reverses, enters the inner pipe 5b, and rises. In these processes, the outdoor hot air in the summer (or the cold outdoor air in the winter) is exchanged with the ground heat that is cooler than the outside air in the summer (or the ground heat that is warmer than the outside air in the winter).
　その後、前記内管５ｂ内を上昇した空気は、前記内管５ｂの上端部の空気排出口５ｂａから前記蓄熱層８内に供給され、前記蓄熱層８内（前記各グリ石１３間の各隙間）を流通する。前記蓄熱層８内に供給された空気は、前記蓄熱層８内を流通する過程で、前記各グリ石１３に自らの熱を伝え蓄熱させると共に前記各グリ石１３との間で熱交換される。その後、前記蓄熱層８内の空気は、前記吹出口７ａから室内に供給される。なお、冬季には、前記ダンパー１１が開放されて前記循環ダクト１０の下端部が前記空気供給室６に空気流通可能に接続される結果、屋根２の近傍の太陽熱で暖められた空気が、前記空気供給室６を介して、前記地中パイプ５の外管５ａと内管５ｂとの間の隙間中に供給される。 Thereafter, the air rising in the inner pipe 5b is supplied into the heat storage layer 8 from the air discharge port 5ba at the upper end of the inner pipe 5b, and the air in the heat storage layer 8 (the gaps between the grits 13). ). The air supplied into the heat storage layer 8 is transmitted through the heat storage layer 8 to transmit heat to the grits 13 and to exchange heat with the grits 13. . Then, the air in the said thermal storage layer 8 is supplied indoors from the said blower outlet 7a. In winter, the damper 11 is opened and the lower end of the circulation duct 10 is connected to the air supply chamber 6 so that air can flow. As a result, the air heated by solar heat in the vicinity of the roof 2 is The air is supplied to the gap between the outer pipe 5 a and the inner pipe 5 b of the underground pipe 5 through the air supply chamber 6.
　前記蓄熱層８内の各グリ石１３は、それ自体が蓄熱機能を有している。よって、例えば夏季には、夜間の時間帯などにおいて、前記各グリ石１３は、前記地中パイプ５からの空気（地中熱と熱交換されて冷やされた空気）と熱交換されることにより十分に冷やされるので、特に暑い昼間の時間帯などにおいては、前記地中パイプ５からの空気は、前記蓄熱層８内で前記各グリ石１３と熱交換されて十分に冷やされてから、室内に供給される。また、例えば冬季には、昼間の時間帯などにおいて、前記各グリ石１３は、前記地中パイプ５からの空気（前記屋根２の下側近傍の太陽熱で暖められた空気が前記地中パイプ５内に送られ、その後、地中熱と熱交換されて更に暖められた空気）と熱交換されることにより十分に暖められるので、特に寒い夜間の時間帯などにおいては、前記地中パイプ５からの空気は、前記蓄熱層８内で前記各グリ石１３と熱交換されて十分に暖められてから、室内に供給される。 The grits 13 in the heat storage layer 8 themselves have a heat storage function. Thus, for example, in the summer, each of the stones 13 is heat-exchanged with air from the underground pipe 5 (air that has been cooled by exchanging heat with underground heat) in a night time zone. Since it is sufficiently cooled, the air from the underground pipe 5 is heat-exchanged with each of the stones 13 in the heat storage layer 8 and sufficiently cooled, especially in the hot daytime period. To be supplied. Further, for example, in winter, in the daytime period, each of the grits 13 is air from the underground pipe 5 (air heated by solar heat near the lower side of the roof 2 is the underground pipe 5). The air is then warmed sufficiently by exchanging heat with the ground heat and then further exchanging heat with the underground heat), especially in the cold night time zone, etc. The air is supplied to the room after being heat-exchanged with the grits 13 in the heat storage layer 8 and sufficiently warmed.
　以上のように、本実施形態１によれば、戸外からの空気を、夏季は地中熱及び前記蓄熱層８内の各グリ石１３と熱交換して十分に冷やした後に、また冬季は地中熱及び前記蓄熱層８内の各グリ石１３と熱交換して十分に暖めた後に、室内に供給することができる。また、本実施形態１では、前述のような熱交換機能を有する蓄熱層８を、建物の外壁面（本実施形態１では外壁１の室内側の面）と前記仕切板７と床面３とにより形成される収容空間１４内に多数のグリ石１３を収容することにより形成している。すなわち、本実施形態１では、前記蓄熱層８のコストを、既築の建物の外壁面（本実施形態１では外壁１の室内側の面）を利用することにより、材料及び施工の両面で大きく低減することができる。よって、本実施形態１によれば、前記蓄熱層８を既築の建物に対して低コストで容易に付加することができるようになり、既築の建物に対して地中熱及び蓄熱層を利用した建物内換気システムを低コストで容易に設置（追加）できるようになる。 As described above, according to the first embodiment, after the outdoor air is sufficiently cooled by exchanging heat with the underground heat and the grits 13 in the heat storage layer 8 in the summer, the air is ground in the winter. After heat is sufficiently exchanged with the medium heat and each of the grits 13 in the heat storage layer 8, they can be supplied indoors. Moreover, in this Embodiment 1, the thermal storage layer 8 which has the above heat exchange functions is made into the outer wall surface of a building (the surface of the indoor side of the outer wall 1 in this Embodiment 1), the said partition plate 7, and the floor surface 3 and It is formed by accommodating a number of grits 13 in the accommodation space 14 formed by the above. That is, in the first embodiment, the cost of the heat storage layer 8 is greatly increased in both materials and construction by using the outer wall surface of the existing building (in the first embodiment, the surface on the indoor side of the outer wall 1). Can be reduced. Therefore, according to the first embodiment, the heat storage layer 8 can be easily added to the existing building at low cost, and the underground heat and the heat storage layer are added to the existing building. The installed building ventilation system can be easily installed (added) at low cost.
　なお、図１Ａ～１Ｃに示す例では、空気供給室６を外壁１の戸外側に設置すると共に蓄熱層８を外壁１の室内側に設置するというように、空気供給室６と蓄熱層８とを別々に設置するようにしているが、このように別々に設置するときは両者を併せた設置スペースが過大となってしまう場合があるので、前記空気供給室６と蓄熱層８とを一箇所に集約し又は一体化して、前記空気供給室６及び蓄熱層８を、外壁１の戸外側だけに設置するか、又は外壁１の室内側だけに設置するようにしてもよい。
　すなわち、本実施形態１では図１Ａ～１Ｃに示すように「空気供給室６と蓄熱層８とを、外壁の外側と内側とにそれぞれ別々に設置する」ようにしているが、本発明ではこれに限られるものではなく、「戸外と蓄熱槽とを繋ぐ空気流路」及び「地中パイプと蓄熱槽とを繋ぐ空気流路」を、「外壁の外側又は内側に設置される蓄熱層」と同じ側に前記蓄熱層と同じスペース内に集約又は一体化するように形成してもよい。このようにした場合、特に蓄熱層を外壁の外側に設置するときは、地中パイプはその蓄熱層の直下に埋設するようにしてもよい。 In the example shown in FIGS. 1A to 1C, the air supply chamber 6 and the heat storage layer 8 are installed such that the air supply chamber 6 is installed outside the outer wall 1 and the heat storage layer 8 is installed on the indoor side of the outer wall 1. However, when installing them separately in this way, the installation space for both may be excessive, so the air supply chamber 6 and the heat storage layer 8 are placed in one place. The air supply chamber 6 and the heat storage layer 8 may be installed only on the outdoor side of the outer wall 1 or only on the indoor side of the outer wall 1.
That is, in the first embodiment, as shown in FIGS. 1A to 1C, “the air supply chamber 6 and the heat storage layer 8 are separately provided on the outer side and the inner side of the outer wall”. It is not limited to "the air flow path connecting the outdoor and the heat storage tank" and "the air flow path connecting the underground pipe and the heat storage tank" with "the heat storage layer installed on the outside or inside of the outer wall" It may be formed on the same side so as to be integrated or integrated in the same space as the heat storage layer.

　〔第５の実施形態〕
次に図５を参照して、本発明の実施形態５に係る、外壁側外気流通蓄熱層を備えた建物内換気システムを説明する。本実施形態５では、蓄熱層２８が外壁１の外側の地盤面４上に設置されている点に特徴がある（これに対して、前記各実施形態１～４では、いずれも、蓄熱層８は外壁１の室内側の床面３上に設置されている)。 [Fifth Embodiment]
Next, with reference to FIG. 5, the ventilation system in a building provided with the outer wall side external air circulation heat storage layer based on Embodiment 5 of this invention is demonstrated. The fifth embodiment is characterized in that the heat storage layer 28 is installed on the ground surface 4 outside the outer wall 1 (in contrast, in each of the first to fourth embodiments, the heat storage layer 8 Is installed on the floor 3 on the indoor side of the outer wall 1).
　すなわち、本実施形態５では、図５（ａ）の側断面図に示すように、外壁１の外側（図示右側）の地盤面４上に、略直方体状の収容空間を形成するための平断面が略コの字状の仕切板２７が設置されている。そして、前記仕切板２７により形成される収容空間内に多数のグリ石が収容、充填されることにより、蓄熱層２８が形成されている。なお、前記収容空間の上方は、多数のグリ石が収容、充填された後に、蓋部２７ｃで閉塞される。 That is, in the fifth embodiment, as shown in the side cross-sectional view of FIG. 5A, a flat cross section for forming a substantially rectangular parallelepiped accommodation space on the ground surface 4 on the outer side (the right side in the figure) of the outer wall 1. A substantially U-shaped partition plate 27 is provided. A heat storage layer 28 is formed by accommodating and filling a large number of grits in the accommodation space formed by the partition plate 27. Note that the upper portion of the accommodation space is closed and closed by a lid portion 27c after a large number of grits are received and filled.
　また、前記収容空間(又は蓄熱層２８)の外側（図示右側）の地盤面４には地中パイプ５が埋設されている。そして、前記地中パイプ５の外管５ａの上端の外気導入口５ａｂが、戸外の空気を取り込み可能に配置されている。また、前記地中パイプ５の内管５ｂの上端の空気排出口５ｂａ（前記地中パイプ５内で地中熱と熱交換された空気を前記蓄熱層２８内に供給するための空気排出口）は、前記蓄熱層２８内に配置されている。 Further, an underground pipe 5 is embedded in the ground surface 4 outside (on the right side in the drawing) of the accommodation space (or the heat storage layer 28). And the outside air introduction port 5ab of the upper end of the outer pipe 5a of the underground pipe 5 is arranged so that outdoor air can be taken in. Also, an air discharge port 5ba at the upper end of the inner pipe 5b of the underground pipe 5 (an air discharge port for supplying air heat-exchanged with underground heat in the underground pipe 5 into the heat storage layer 28). Is disposed in the heat storage layer 28.
　また、前記蓄熱層２８内の図示上方には吹出用パイプ２７ｂが配置されている。前記吹出用パイプ２７ｂの一方の開口端部は、室内側に向けて配置され、前記蓄熱層２８内で熱交換された空気を室内に供給する吹出口２７ａとなっている。 In addition, an outlet pipe 27b is disposed in the heat storage layer 28 in the upper part of the figure. One opening end portion of the blowout pipe 27b is disposed toward the indoor side, and serves as a blowout port 27a that supplies the air heat-exchanged in the heat storage layer 28 to the room.
　以上のように、本実施形態５では、前記蓄熱層２８が外壁１の外側に設置されている点で前記各実施形態１～４と異なっているが、戸外からの空気を地中パイプ５中に導入してその中で流通させながら地中熱と熱交換させ、その後、この空気を蓄熱層２８内に送って其処でも熱交換させてから室内に供給するという基本的構造は同じである。よって、本実施形態５によっても、前記各実施形態１～４とほぼ同様の作用効果を奏することができる。なお、図５（ａ）では、前記収容空間を、平断面が略コの字状の仕切板２７と外壁１の外側の面などで構成する（すなわち、前記収容空間を区画する建物側の面を建物の外壁１それ自体により構成する）ようにしている（図１Ｃも参照）が、本発明では、前記収容空間を平断面が略ロの字状の仕切板で形成するようにしてもよい。また、図５（ａ）で示す例では、前記収容空間の底面を板又はコンクリート製などの板状部材により構成するようにしているが、この底面を構成する板状部材を無くして、前記収容空間の底面を地盤面４により構成するようにしてもよい。 As described above, the fifth embodiment is different from the first to fourth embodiments in that the heat storage layer 28 is installed on the outside of the outer wall 1. The basic structure is the same, in which heat is exchanged with the underground heat while being introduced into the heat exchanger, and then the air is sent into the heat storage layer 28, where it is also heat exchanged and supplied to the room. Therefore, the fifth embodiment can provide substantially the same effects as the first to fourth embodiments. In FIG. 5A, the accommodation space is configured by a partition plate 27 having a substantially U-shaped cross section and an outer surface of the outer wall 1 (that is, a building-side surface that divides the accommodation space). (See also FIG. 1C), but in the present invention, the housing space may be formed by a partition plate having a substantially square cross section. . Further, in the example shown in FIG. 5A, the bottom surface of the housing space is configured by a plate-like member such as a plate or concrete, but the plate-like member constituting the bottom surface is eliminated and the housing is accommodated. The bottom surface of the space may be configured by the ground surface 4.
　次に、図５（ｂ）は本実施形態５の変形例を示す側断面図である。この変形例では、図５（ｂ）に示すように、地中パイプ５が、前記仕切板２７等で形成される収容空間(又は蓄熱層２８)の外側（図示右側）の地盤面４から地中にではなく、前記収容空間(又は蓄熱層２８)の下方の地盤面４から地中に埋設されている。そのため、この変形例では、前記地中パイプ５の地盤面４より上方の部分は前記蓄熱層２８内に配置され、前記地中パイプ５の外管５ａの上端の外気導入口５ａｂだけが、前記収容空間（前記仕切板２７）から外側に向けて、外気を取り込み可能に、戸外に露出されている。このような変形例によっても前記図５（ａ）に示した例と同様の作用効果を奏することができる。 Next, FIG. 5B is a side sectional view showing a modification of the fifth embodiment. In this modification, as shown in FIG. 5 (b), the underground pipe 5 is grounded from the ground surface 4 on the outside (right side in the drawing) of the accommodation space (or the heat storage layer 28) formed by the partition plate 27 or the like. It is buried in the ground not from the inside but from the ground surface 4 below the accommodation space (or the heat storage layer 28). Therefore, in this modification, the portion above the ground surface 4 of the underground pipe 5 is disposed in the heat storage layer 28, and only the outside air inlet 5ab at the upper end of the outer pipe 5a of the underground pipe 5 is The outside space is exposed to the outside so as to be able to take in outside air from the housing space (the partition plate 27) toward the outside. Also by such a modification, the same effect as the example shown to the said Fig.5 (a) can be show | played.
　〔第６の実施形態〕
次に図６を参照して、本発明の実施形態６に係る、外壁側外気流通蓄熱層を備えた建物内換気システムを説明する。本実施形態６では、蓄熱層２８を構成する多数のグリ石１３を収容するための収容空間３４を、外壁１とは独立に移動・運搬可能な製品として製造された略箱状の容器（上方が開口部となっているケース）３７により構成している点に特徴がある（これに対して、前記各実施形態１～５では、いずれも、多数のグリ石１３が収容される収容空間（又は蓄熱層８，２８）を、建物の外壁１を利用して形成するようにしていた）。 [Sixth Embodiment]
Next, with reference to FIG. 6, the ventilation system in a building provided with the outer wall side external air circulation heat storage layer based on Embodiment 6 of this invention is demonstrated. In the sixth embodiment, the storage space 34 for storing a large number of grits 13 constituting the heat storage layer 28 is formed in a substantially box-shaped container (upper side) manufactured as a product that can be moved and transported independently of the outer wall 1. (In contrast, in each of the first to fifth embodiments, the accommodation space (which accommodates a large number of grits 13) is characterized. Alternatively, the heat storage layer 8, 28) is formed using the outer wall 1 of the building).
　すなわち、本実施形態６では、前記容器３７は、木材、プラスチック、発泡体、又はコンクリートなどの断熱性素材により、独立に移動・運搬可能な製品として、工場などで製造される。また前記容器３７の下方部分には前記地中パイプ５の内管５ｂからの空気を前記容器３７内に導入するための導入口３７ｂが形成されており、前記容器３７の上方部分には前記容器３７内からの空気を室内に供給するための吹出口３７ａが形成されている。 That is, in the sixth embodiment, the container 37 is manufactured at a factory or the like as a product that can be independently moved and transported by a heat insulating material such as wood, plastic, foam, or concrete. In addition, an inlet 37b for introducing air from the inner pipe 5b of the underground pipe 5 into the container 37 is formed in the lower part of the container 37. The blower outlet 37a for supplying the air from the inside to the room | chamber 37 is formed.
　なお図６において、３７ｃは前記容器３７内に多数のグリ石１３を充填した後に前記容器３７の上方の開口部（収容空間３４の上方部分）を塞ぐための蓋部である。また図６において、前記地中パイプ５の外管５ａと内管５ｂとの間の隙間に戸外からの空気を導入するための構成は、前記各実施形態１～５と同様であるので、図示を省略する。 In FIG. 6, reference numeral 37 c denotes a lid for closing the opening above the container 37 (the upper part of the accommodating space 34) after filling the container 37 with a large number of grits 13. In FIG. 6, the configuration for introducing the air from the outside into the gap between the outer pipe 5a and the inner pipe 5b of the underground pipe 5 is the same as in the first to fifth embodiments. Is omitted.
　以上のように、本実施形態６によれば、前記各実施形態１～５と同様の基本的効果を奏することに加えて、前記蓄熱層２８を外壁１とは独立に移動・運搬可能な断熱性の容器３７により構成するようにしたので、例えば工場で大量生産した前記容器３７を建物の所望の位置に運んで設置するだけで前記蓄熱層２８を形成することができ、前記蓄熱層２８の施工を極めて低コストで且つ効率よく行うことができる。 As described above, according to the sixth embodiment, in addition to the same basic effects as the first to fifth embodiments, the heat storage layer 28 can be moved and transported independently of the outer wall 1. For example, the heat storage layer 28 can be formed simply by transporting and installing the container 37 mass-produced in a factory to a desired position in a building. Construction can be performed at an extremely low cost and efficiently.
　以上、本発明の各実施形態について説明したが、本発明はこれに限られるものではなく様々な変更が可能である。例えば、前記各実施形態１～６においては、前記地中パイプ５は、いずれも、戸外からの空気を外管５ａと内管５ｂとの間の隙間に導入して下降させた後に外管５ａの底部で衝突、反転させて内管５ｂ内に入れて上昇させてから前記蓄熱層８，２８内に供給するものとして構成したが、本発明では、前記と逆に、前記地中パイプ５を、戸外からの空気を内管５ｂの内部に導入して下降させた後に外管５ａの底部で衝突、反転させて外管５ａと内管５ｂとの隙間に入れてその中を上昇させてから前記蓄熱層８，２８内に供給するものとして構成してもよい。
　すなわち、前記各実施形態１～６においては、いずれも、戸外からの外気が、まず蓄熱層８，２８内に移動してその内部を流通し、その後、地中パイプ５に移動してその内部を流通し、その後、室内に移動するという外気の流れを形成するシステムを、例示した。しかし、本発明はこれに限られるものではなく、戸外からの外気が、まず地中パイプ５内に移動してその内部を流通し、その後、蓄熱層８，２８内に移動してその内部を流通し、その後、室内に移動するという外気の流れを形成するシステム、としてもよい。 As mentioned above, although each embodiment of this invention was described, this invention is not restricted to this, A various change is possible. For example, in each of the first to sixth embodiments, each of the underground pipes 5 has the outer pipe 5a after the air from the outside is introduced and lowered into the gap between the outer pipe 5a and the inner pipe 5b. However, in the present invention, the underground pipe 5 is connected to the heat storage layers 8 and 28 after being collided at the bottom of the tube, reversed and then moved up into the inner tube 5b. After the air from the outside is introduced and lowered into the inner pipe 5b, it collides with the bottom of the outer pipe 5a, reverses it, puts it in the gap between the outer pipe 5a and the inner pipe 5b, and raises the inside. You may comprise as what supplies in the said thermal storage layer 8,28.
That is, in each of the first to sixth embodiments, outside air from the outside first moves into the heat storage layers 8 and 28 and circulates through the inside, and then moves to the underground pipe 5 and moves to the inside. The system which forms the flow of the outside air that circulates and then moves indoors is illustrated. However, the present invention is not limited to this, and outside air from the outside first moves into the underground pipe 5 and circulates in the underground pipe 5, and then moves into the heat storage layers 8 and 28 and passes through the inside. It is good also as a system which forms the flow of the outside air which distribute | circulates and moves to a room | chamber interior after that.
　また、前記各実施形態１～６においては、前記地中パイプ５と前記蓄熱層８，２８との関係について、いずれも、まず地中パイプ５内で空気を地中熱と熱交換させ、その後に前記の地中熱と熱交換させた空気を蓄熱層８，２８内に供給して其処で更に熱交換させ、このようにして２段階で熱交換させた空気を室内ニ供給するように構成したが、本発明では、前記と逆に、まず蓄熱層８，２８内に戸外からの空気を取り込んで其処で熱交換させ、前記の蓄熱層８，２８内で熱交換させた空気を更に地中パイプ５内に導入して地中熱と熱交換させ、このようにして２段階で熱交換させた空気を前記地中パイプ５から室内に供給するようにしてもよい。 In each of the first to sixth embodiments, regarding the relationship between the underground pipe 5 and the heat storage layers 8 and 28, first, air is first exchanged with underground heat in the underground pipe 5, and thereafter The air exchanged with the ground heat is supplied to the heat storage layers 8 and 28 and further heat exchanged there, and thus the air exchanged in two stages is supplied indoors. However, in the present invention, contrary to the above, first, air from the outside is taken into the heat storage layers 8 and 28 and heat exchange is performed there, and the air that has been heat exchanged inside the heat storage layers 8 and 28 is further grounded. The air that has been introduced into the middle pipe 5 and exchanged with the underground heat and thus exchanged heat in two stages may be supplied from the underground pipe 5 into the room.
　また、前記各実施形態１～６においては、前記収容空間１４，３４内に多数のグリ石１３を収容、充填することにより蓄熱層８，２８を構成するようにしたが、本発明においては、これに限られることなく、例えば前記収容空間１４，３４内に、前記多数のグリ石１３に代えて、従来より公知の、蓄熱機能を有する各蓄熱体（例えば、約２０～２３℃で液体状からゲル状に遷移する公知の蓄熱体、石又は岩自らが吸・放湿性又は空気浄化機能を有している例えばゼオライト岩とか珪藻岩などの素材から成る蓄熱体など）を収容、充填することにより前記蓄熱層８，２８を構成するようにしてもよい。さらに、前記各実施形態１～６において、前記蓄熱層８，２８は、いずれも、地盤面４の上方に配置するようにしたが、本発明においては、前記蓄熱層８，２８を、地盤面４の上方だけでなく地盤面４の下方の地中まで延長させるようにしてもよい。 Further, in each of the first to sixth embodiments, the heat storage layers 8 and 28 are configured by accommodating and filling a large number of grits 13 in the accommodation spaces 14 and 34. In the present invention, Without being limited thereto, for example, in the storage spaces 14 and 34, instead of the large number of grits 13, each heat storage body having a heat storage function known in the art (for example, liquid at about 20 to 23 ° C.) Contain and fill a known heat storage body that transitions from a gel to a gel, or a stone or rock that itself has a function of absorbing, releasing moisture or purifying air (for example, a heat storage body made of a material such as zeolite rock or diatomite). The heat storage layers 8 and 28 may be configured as described above. Further, in each of the first to sixth embodiments, each of the heat storage layers 8 and 28 is disposed above the ground surface 4, but in the present invention, the heat storage layers 8 and 28 are disposed on the ground surface.
