【発明の属する技術分野】
本発明は換気装置および床暖房装置を備えた建物に関する。
【０００２】
【従来の技術】
従来の建物の床暖房装置は床支持体の上に発熱パネルを搭載し、発熱パネルの上に床仕上材を敷設し、電力が発熱パネルに供給されることで、発熱パネルが熱を発生し、その熱が床仕上材を暖めている（例えば、特許文献１参照）。

特開２００３−２１３４９号公報（第１頁、要約、図１）
【０００４】
【発明が解決しようとする課題】
しかしながら、従来例は人の歩く床仕上材を発熱パネルで直接的に暖める構造であるため、例えば、２階建て以上の建物の場合には、２階以上における部屋ごとの床仕上材にも発熱パネルを敷設する必要があるという問題点があった。
【０００５】
そこで、本発明は、建物のべた基礎に温媒循環式の蓄熱体を設けることで、部屋の床に蓄熱体を設けることなく、部屋を適切に暖めることができる換気装置および床暖房装置を備えた建物を提供するものである。
【０００６】
【課題を解決するための手段】
本発明に係る換気装置および床暖房装置を備えた建物は、建物の外部に設置されたボイラーで暖められた温媒が部屋と対応するべた基礎に設けられたコンクリート製の蓄熱体を暖めることによって、部屋の床に蓄熱体を設ける必要がなく、熱交換換気機器の動作で屋外の外気が熱交換換気機器の熱交換体を経由して熱交換換気機器と同じ空間における吸気管から蓄熱体に吹き出され、吹き出された外気が蓄熱体に接触して暖められた内気になり、蓄熱体で温められた内気の一部が部屋の吸込口から部屋に導入され、部屋に導入された内気が部屋の上部における排気管の吸込口から排気管を経由して熱交換換気機器に到達し、蓄熱体で暖められた内気の別の一部が部屋の内壁どうしの間に形成された空間や部屋の内壁と外壁との間に形成された空間を経由して屋根裏における排気管の吸込口から排気管を経由して熱交換換気機器に到達し、熱交換換気機器の熱交換体が内気の熱と外気の熱とを交換して外気を温める蓄熱体の負担を軽減することができる。
【０００７】
【発明の実施の形態】
図１から図３は一実施形態であって、図１は床暖房装置２１における蓄熱体２６を縦方向に切断した断面を示し、図２は建物１における１階の各部屋６に対する輸送管２５の平面的な配管を示し、図３は建物１を縦方向に切断した断面を示す。
【０００８】
図３を参照し、第１種換気装置１１および床暖房装置２１を備えた建物１について２階建ての家屋を例として説明する。建物１はべた基礎と呼ばれるコンクリートからなる基礎２の上に柱３を建て、柱３の上に屋根４を載せ、柱３の外側に外壁５を形成し、柱３と屋根４および外壁５で囲まれた内部に下層階である１階の部屋６と上層階である２階の部屋６とを備える。図示は省略したが、建物１は外壁５の内側および屋根４の内側に図外の断熱材を敷設した外断熱構造になっている。
【０００９】
第１種換気装置１１は熱交換換気機器１２と吸気管１５および排気管１７を備える。熱交換換気機器１２は図外のフィルタとモータとファンおよび熱交換体を内蔵した構造であって、部屋６を形成する内壁７と外壁５との間に形成された空間Ａに配置されて外壁５に取り付けられる。熱交換換気機器１２の屋外吸気口１３と屋外排気口１４は外壁５を貫通して外壁５の外側に突出する。熱交換換気機器１２における図外の屋内吸気口に接続された吸気管１５は内壁７と外壁５との間に形成された空間Ａを経由して基礎２と１階の部屋６における床８との間に形成された空間Ｂに配管される。吸気管１５は床暖房装置２１の蓄熱体２６に対応する吹出口１６を備える。熱交換換気機器１２における図外の屋内排気口に接続された排気管１７は内壁７と外壁５との間に形成された空間Ａを経由して屋根裏Ｄに配管される。排気管１７には屋根裏Ｄや１階の部屋６における天井および２階の部屋６における天井のそれぞれに開口された吸込口１８を備える。１階および２階の部屋６のそれぞれにおける内壁７には吸込口１９が部屋６の内壁７における下部に形成される。
【００１０】
そして、第１種換気装置１１にあっては、熱交換換気機器１２のモータがファンを回転することで、屋外の外気が屋外吸気口１３から吸い込まれてフィルタで塵埃を除去され、この塵埃の除去された外気が吸気管１５を経由して吹出口１６から蓄熱体２６に向けて吹き出される。この吹出口１６から吹き出された外気は蓄熱体２６に接触し、蓄熱体２６で暖められた内気となる。この温められた内気の一部は各部屋６の吸込口１９から部屋６に導入され、各部屋６の暖かな内気の一部が各部屋６の天井における吸込口１８に吸い込まれる。また、上記蓄熱体２６で暖められた内気の別の一部が各部屋６の内壁７どうしの間に形成された空間Ｃや各部屋６の内壁７と外壁５との間に形成された空間Ａを経由して屋根裏Ｄにおける吸込口１８に吸い込まれる。このように蓄熱体２６で温められた清浄な内気が矢印で示すように建物１の内部を循環して１階および２階の部屋６を内側および外側から温めるので、暖房の必要な季節において、塵埃の除去されて暖められた内気の循環で健康的に暖房された居住空間を作ることができる。上記吸込口１８に吸い込まれた内気が排気管１７を経由して屋外排気口１４から屋外に排出される場合に、熱交換換気機器１２における熱交換体が排気管１７から屋外排気口１４に送られる内気の熱と屋外吸気口１３から吸気管１５に送られる外気の熱とを交換する。このように吹出口１６から蓄熱体２６に吹き付けられる外気が熱交換換気機器１２による内気との熱交換で温められているので、外気を温める蓄熱体２６の負担が軽減される。
【００１１】
床暖房装置２１は水と不凍液との混合された温媒を閉鎖管路に循環させる構造であって、ボイラー２２と輸送管２５および蓄熱体２６を備える。ボイラー２２は図外の熱源とモータとポンプと熱交換器および制御部を備えた構造であって、屋外に設置される。蓄熱体２６は基礎２における１階の部屋６と対応して設けられる。輸送管２５の一端はボイラー２２の吐出口２３に接続され、輸送管２５の他端はボイラー２２の取入口２４に接続され、輸送管２５の中間部は蓄熱体２６に埋設される。ボイラー２２のポンプおよび熱交換器や輸送管２５には温媒が封入されている。熱交換管を加熱するボイラー２２の熱源としては電気でもよいが、灯油のような燃料を使用すればボイラー２２の維持費が電気よりも安くなる。そして、床暖房装置２１では、ボイラー２２のモータがポンプを駆動することで、温媒が輸送管２５からボイラー２２の熱交換管に送られ、熱源で加熱された熱交換管が温媒を暖め、暖められた温媒が輸送管２５で蓄熱体２６に送られて蓄熱体２６を暖める一方、蓄熱体２６で熱を奪われて冷えた温媒が輸送管２５からボイラー２２の熱交換管に送られる。ポンプと熱交換管および輸送管２５が上記閉鎖管路を形成する。ボイラー２２の制御部は蓄熱体２６と１階の部屋６の床８との間における空間Ｂに設置された図外の温度感知器から入力された検出温度が人の操作で制御部に設定された目標温度となるように熱源をフィードバック制御する。例えば、人が目標温度を例えば２３℃と設定した場合、制御部は検出温度が目標温度よりも低ければ熱源を駆動し、その熱源の駆動後に、検出温度が目標温度より例えば２℃高い温度に到達すると、熱源の駆動を停止し、その熱源の停止後に、検出温度が目標温度より例えば２℃低い温度に到達すると、熱源を駆動するというようになっている。
【００１２】
よって、床暖房装置２１の温媒で暖められた蓄熱体２６が第１種換気装置１１の熱交換換気機器１２で暖められて蓄熱体２６に向けて吹き出された外気を暖めることで、暖められた内気を作る。この暖められた内気の一部は各部屋６の内装の周囲に形成された空間Ａ；Ｂ；Ｃを経由して屋根裏Ｄに向けて上昇する過程で、各部屋６の内装を暖める。また、上記蓄熱体２６で暖められた内気の別の一部は各部屋６の吸込口１８から各部屋６に導入される。このように、第１種換気装置１１による空気の流れと床暖房装置２１による暖気生成との有機的な組み合わせによって、暖房の必要な季節に、各部屋６を快適な居住空間にすることができる。床暖房装置２１が輸送管２５とボイラー２２とに封入されて循環する温媒をボイラー２２の熱交換器で暖める構造であるので、温媒を暖めるボイラー２２における熱源の消費量を低減することができる。
【００１３】
図１を参照し、床暖房装置２１における蓄熱体２６の内部構造について説明する。硬質断熱材２７が基礎２における一方の基礎部２８と他方の基礎部２８とこれらの基礎部２８に連接されたスラブ部２９との内側に敷設される。硬質断熱材２７は封袋にガラスウールのような断熱材繊維を密封したような圧縮性に富む形態ではなく、断熱材料を樹脂成形で工場生産された圧縮されづらい形態に形成された押出発泡ポリスチレンフォームのような板状であって、その板状の硬質断熱材２７が現場で養生の終わった基礎２に施工される。硬質断熱材２７の上には鉄筋としてのワイヤメッシュ３０が敷設される。輸送管２５は例えば三菱産資株式会社製の商品名Ｏ^２ストップたる架橋ポリエチレン管が使用され、ワイヤメッシュ３０の上に蛇行した配管形態で敷設される。ワイヤメッシュ３０に敷設された輸送管２５は軟鉄からなる図外の結束線でワイヤメッシュ３０に結束されることによって、輸送管２５がワイヤメッシュ３０に固定される。
【００１４】
ワイヤメッシュ３０の上に敷設された輸送管２５の両端部は基礎部２８に上端面から下方に窪むように形成された切欠部３２および硬質断熱材２７に形成され貫通孔３３から隣のスラブ部２９の方向に引き出される。その状態において、蓄熱体２６の材料であるコンクリートが現場打ちされる。具体的には、蓄熱体２６の材料である混練された生コンのようなコンクリートが硬質断熱材２７で囲まれた空間に流し込まれて養生されることで、ワイヤメッシュ３０と輸送管２５および結束線をコンクリートに埋め込んだ形態の蓄熱体２６が形成される。基礎部２８は図３における建物１の土台を載せる部分である。スラブ部２９は図３における各部屋６の床８と空間Ｂを形成しつつ上下方向に対応する部分である。切欠部３２は貫通孔であってもよいが、上方の開放された切欠部３２であれば、輸送管２５の中間部を上方から切欠部３２に挿入すればよいので、輸送管２５の一端から挿入しなければならない貫通孔に比べて、輸送管２５の配管作業が容易である。貫通孔３３は上方の開方された切欠部であってもよいが、上方の閉鎖された貫通孔３３であれば、貫通孔３３の周りの硬質断熱材２７が空間に流し込まれた蓄熱体２６の材料であるコンクリートを基礎部２８の方に溢れ出ないように型枠の働きを行う。蓄熱体２６がべた基礎と呼ばれる基礎２に硬質断熱材２７を介在させて形成されているので、地面からの湿気による影響を受けない。蓄熱体２６と基礎２のスラブ部２９との間に配置された断熱材が硬質断熱材２７であるので、蓄熱体２６の材料である生コンのようなコンクリートが現場打ちされる場合に硬質断熱材２７が当該現場打ちされるコンクリートに対しワイヤメッシュ３０や輸送管２５を設置形態で適切な位置に支持することができる。硬質断熱材２７の上に図外のスペーサを置き、そのスペーサの上にワイヤメッシュ３０を置くことで、ワイヤメッシュ３０および輸送管２５を蓄熱体２６の内部に埋め込む形態であっても、同様に適用することができる。
【００１５】
図２を参照し、建物１における１階の各部屋６に対する輸送管２５の配管について説明する。輸送管２５はボイラー２２の吐出口２３から基礎部２８および硬質断熱材２７（図１参照）を外側から或る１つの部屋６と対応する部分の側に貫通し、その１つの部屋６と対応する部分で蛇行しつつ配管された後、当該１つの部屋６と隣のもう１つの部屋６との境にある基礎部２８および硬質断熱材２７を貫通して隣の１つの部屋６と対応する部分で蛇行しつつ配管された後、上記隣の１つの部屋６と更なる隣の１つの部屋６との境にある基礎部２８および硬質断熱材２７を貫通して更なる隣の１つの部屋６と対応する部分で蛇行しつつ配管されというように、各部屋６と対応する部分で蛇行しつつ配管され、最後の部屋６と対応する部分から基礎部２８および硬質断熱材２７を外側に貫通してボイラー２２の取入口２４に至る。各部屋６と対応する部分において、野菜の熱的な劣化を防止するために、輸送管２５は台所の野菜を収納する部分に配管されない。また、輸送管２５が居間や食堂などの人の行き交う部分や座る部分および寝る部分などの居住部分には蛇行する輸送管２５どうしの間隔を均等となるように配管されることで、居住部分を一様な温度で全体的に温めることができる。よって、蓄熱体２６が蛇行配管された輸送管２５から伝達された熱で全体的に一様に暖められ、その暖められた蓄熱体２６が蓄熱体２６の上に空間Ｂを介して設けられた建物１における１階の部屋６の床８を全体的に一様に暖めることができる。図２において、３４は玄関の土間、３５は便所、３６は洗面所、３７は浴室、３９はキッチンセットを示す。
【００１６】
上記のように基礎２の作られた建築現場において、硬質断熱材２７の設置、ワイヤメッシュ３０の設置、輸送管２５の配管、図外の結束線による結束、生コンのようなコンクリートの打設などの施工を順に行うことによって、蓄熱体２６が現場で作られるので、工場生産された蓄熱体２６を現場に運んで設置する場合に比べ、蓄熱体２６が基礎２の蓄熱体２６を設けるべき位置に適切に設置できる。

It is not necessary to install a heat storage body on the floor of the room, and the outdoor air from the outside passes through the heat exchanger of the heat exchange ventilator and moves from the intake pipe to the heat accumulator in the same space as the heat exchange ventilator. The outside air that has been blown out and touched the heat storage body becomes warmed inside air, and a part of the inside air heated by the heat storage body is introduced into the room from the room inlet, and the inside air introduced into the room is the room The other part of the inside air warmed by the heat accumulator reaches the heat exchange ventilator via the exhaust pipe from the exhaust pipe inlet at the upper part of the room or the room Formed between inner wall and outer wall The heat exchange ventilator reaches the heat exchange ventilator via the exhaust pipe from the inlet of the exhaust pipe in the attic via the gap, and the heat exchanger of the heat exchanging ventilator exchanges the heat of the inside air and the heat of the outside air to remove the outside air The burden of the heat storage body to warm can be reduced.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an embodiment, and FIG. 1 shows a cross section of a heat storage body 26 in a floor heating device 21 cut in a vertical direction. FIG. 2 shows a transport pipe 25 for each room 6 on the first floor in a building 1. FIG. 3 shows a cross section of the building 1 cut in the longitudinal direction.
[0008]
With reference to FIG. 3, the building 1 provided with the 1st type ventilation apparatus 11 and the floor heating apparatus 21 is demonstrated as an example for a two-story house. The building 1 has a pillar 3 built on a concrete foundation 2 called a solid foundation, a roof 4 is placed on the pillar 3, an outer wall 5 is formed outside the pillar 3, and the pillar 3, roof 4, and outer wall 5 are A room 6 on the first floor, which is the lower floor, and a room 6 on the second floor, which is the upper floor, are provided in the enclosed interior. Although not shown, the building 1 has an outer heat insulating structure in which a heat insulating material (not shown) is laid on the inner side of the outer wall 5 and the inner side of the roof 4.
[0009]
The first type ventilation device 11 includes a heat exchange ventilation device 12, an intake pipe 15, and an exhaust pipe 17. The heat exchange ventilator 12 has a structure including a filter, a motor, a fan, and a heat exchanger that are not shown in the figure, and is arranged in a space A formed between the inner wall 7 and the outer wall 5 forming the room 6, and is attached to the outer wall. 5 is attached. The outdoor intake port 13 and the outdoor exhaust port 14 of the heat exchange ventilation device 12 penetrate the outer wall 5 and project outside the outer wall 5. An intake pipe 15 connected to an indoor intake port (not shown) in the heat exchange ventilation device 12 passes through a space A formed between the inner wall 7 and the outer wall 5, and the floor 8 in the room 6 on the first floor room 6. It is piped in the space B formed between the two. The intake pipe 15 includes an air outlet 16 corresponding to the heat storage body 26 of the floor heating device 21. An exhaust pipe 17 connected to an indoor exhaust port (not shown) in the heat exchange ventilator 12 is piped to the attic D via a space A formed between the inner wall 7 and the outer wall 5. The exhaust pipe 17 is provided with a suction port 18 opened to the attic D, the ceiling in the room 6 on the first floor, and the ceiling in the room 6 on the second floor. A suction port 19 is formed in the lower part of the inner wall 7 of the room 6 in the inner wall 7 of each of the rooms 6 on the first floor and the second floor.
[0010]
In the first type ventilation device 11, the motor of the heat exchange ventilation device 12 rotates the fan, so that outdoor outdoor air is sucked from the outdoor air intake port 13 and dust is removed by a filter. The removed outside air is blown out from the blower outlet 16 toward the heat storage body 26 via the intake pipe 15. The outside air blown out from the outlet 16 comes into contact with the heat storage body 26 and becomes the inside air warmed by the heat storage body 26. A part of this warmed inside air is introduced into the room 6 from the inlet 19 of each room 6, and a part of the warm inside air of each room 6 is sucked into the inlet 18 on the ceiling of each room 6. Further, a space C in which another part of the inside air heated by the heat storage body 26 is formed between the inner walls 7 of each room 6 or a space formed between the inner wall 7 and the outer wall 5 of each room 6. It is sucked into the suction port 18 in the attic D via A. As the clean inside air heated by the heat storage body 26 circulates inside the building 1 as indicated by the arrows and heats the rooms 6 on the first floor and the second floor from the inside and outside, in the season when heating is required, It is possible to create a healthy heated living space by circulating the inside air heated by removing dust. When the inside air sucked into the suction port 18 is exhausted from the outdoor exhaust port 14 via the exhaust pipe 17, the heat exchanger in the heat exchange ventilator 12 is sent from the exhaust pipe 17 to the outdoor exhaust port 14. The heat of the inside air is exchanged with the heat of the outside air sent from the outdoor intake port 13 to the intake pipe 15. Thus, since the external air blown from the blower outlet 16 to the heat storage body 26 is warmed by heat exchange with the internal air by the heat exchange ventilator 12, the burden on the heat storage body 26 that warms the external air is reduced.
[0011]
The floor heating device 21 is configured to circulate a heating medium in which water and antifreeze liquid are mixed in a closed pipeline, and includes a boiler 22, a transport pipe 25, and a heat storage body 26. The boiler 22 has a structure including a heat source, a motor, a pump, a heat exchanger, and a control unit (not shown), and is installed outdoors. The heat storage body 26 is provided corresponding to the first floor room 6 in the foundation 2. One end of the transport pipe 25 is connected to the discharge port 23 of the boiler 22, the other end of the transport pipe 25 is connected to the intake port 24 of the boiler 22, and an intermediate portion of the transport pipe 25 is embedded in the heat storage body 26. A heating medium is sealed in the pump, heat exchanger, and transport pipe 25 of the boiler 22. Electricity may be used as a heat source for the boiler 22 that heats the heat exchange tube, but if a fuel such as kerosene is used, the maintenance cost of the boiler 22 is lower than electricity. In the floor heating device 21, when the motor of the boiler 22 drives the pump, the heating medium is sent from the transport pipe 25 to the heat exchange pipe of the boiler 22, and the heat exchange pipe heated by the heat source warms the heating medium. The heated heating medium is sent to the heat storage body 26 by the transport pipe 25 to warm the heat storage body 26, while the heat medium that has been deprived of heat by the heat storage body 26 and cooled is transferred from the transport pipe 25 to the heat exchange pipe of the boiler 22. Sent. The pump, the heat exchange pipe, and the transport pipe 25 form the closed pipe line. The control unit of the boiler 22 is set in the control unit by a human operation with a detected temperature input from a temperature sensor (not shown) installed in the space B between the heat storage body 26 and the floor 8 of the room 6 on the first floor. The heat source is feedback controlled to achieve the target temperature. For example, when a person sets the target temperature to, for example, 23 ° C., the control unit drives the heat source if the detected temperature is lower than the target temperature, and after the heat source is driven, the detected temperature becomes a temperature that is 2 ° C. higher than the target temperature. When the temperature reaches, the driving of the heat source is stopped. After the heat source is stopped, when the detected temperature reaches, for example, 2 ° C. lower than the target temperature, the heat source is driven.
[0012]
Therefore, the heat storage body 26 warmed by the heating medium of the floor heating device 21 is warmed by warming the outside air that is warmed by the heat exchange ventilator 12 of the first type ventilation device 11 and blown toward the heat storage body 26. Make shyness. A part of the warmed air warms the interior of each room 6 in the process of rising toward the attic D via the spaces A; B; C formed around the interior of each room 6. Further, another part of the inside air warmed by the heat storage body 26 is introduced into each room 6 from the suction port 18 of each room 6. Thus, by the organic combination of the air flow by the first type ventilation device 11 and the warm air generation by the floor heating device 21, each room 6 can be made into a comfortable living space in the season when heating is required. . Since the floor heating device 21 has a structure in which the heating medium enclosed and circulated in the transport pipe 25 and the boiler 22 is heated by the heat exchanger of the boiler 22, the consumption of the heat source in the boiler 22 for heating the heating medium can be reduced. it can.
[0013]
With reference to FIG. 1, the internal structure of the heat storage body 26 in the floor heating apparatus 21 will be described. A hard heat insulating material 27 is laid inside one foundation portion 28 of the foundation 2, the other foundation portion 28, and a slab portion 29 connected to these foundation portions 28. The hard heat insulating material 27 is not a highly compressible form in which heat insulating material fibers such as glass wool are sealed in a sealed bag, but an extruded expanded polystyrene formed into a form that is hard to be compressed and is produced by resin molding of the heat insulating material. It is plate-like like foam, and the plate-like hard heat insulating material 27 is applied to the foundation 2 that has been cured on site. A wire mesh 30 as a reinforcing bar is laid on the hard heat insulating material 27. The transport pipe 25 is, for example, a cross-linked polyethylene pipe having a product name O ² stop manufactured by Mitsubishi Sansei Co., Ltd., and is laid in a meandering pipe form on the wire mesh 30. The transport pipe 25 laid on the wire mesh 30 is bound to the wire mesh 30 by a binding wire (not shown) made of soft iron, whereby the transport pipe 25 is fixed to the wire mesh 30.
[0014]
Both end portions of the transport pipe 25 laid on the wire mesh 30 are formed in the base portion 28 with a notch 32 formed so as to be depressed downward from the upper end surface and the hard heat insulating material 27, and the adjacent slab portion 29 from the through hole 33. Pulled out in the direction of. In that state, the concrete, which is the material of the heat storage body 26, is cast in the field. Specifically, concrete such as kneaded raw concrete that is a material of the heat storage body 26 is poured into a space surrounded by the hard heat insulating material 27 and cured, so that the wire mesh 30, the transport pipe 25, and the binding wire are cured. The heat storage body 26 in the form of being embedded in concrete is formed. The base portion 28 is a portion on which the foundation of the building 1 in FIG. 3 is placed. The slab portion 29 is a portion corresponding to the vertical direction while forming the floor 8 and the space B of each room 6 in FIG. The cutout portion 32 may be a through hole, but if the cutout portion 32 is opened upward, an intermediate portion of the transport pipe 25 may be inserted into the cutout portion 32 from above, so that one end of the transport pipe 25 can be inserted. The piping work of the transport pipe 25 is easier than the through hole that must be inserted. The through hole 33 may be a notched part opened upward, but if the through hole 33 is closed above, the heat storage body 26 in which the hard heat insulating material 27 around the through hole 33 is poured into the space. The work of the mold is performed so that the concrete, which is the material, does not overflow toward the foundation portion 28. Since the heat storage body 26 is formed by interposing a hard heat insulating material 27 on the foundation 2 called a solid foundation, it is not affected by moisture from the ground. Since the heat insulating material disposed between the heat storage body 26 and the slab portion 29 of the foundation 2 is the hard heat insulating material 27, the hard heat insulating material is used when concrete such as ready-mixed concrete that is the material of the heat storage body 26 is cast in the field. The wire mesh 30 and the transport pipe 25 can be supported at appropriate positions in the installation form with respect to the concrete 27 in-placed. Even if the wire mesh 30 and the transport pipe 25 are embedded in the heat storage body 26 by placing a spacer (not shown) on the hard heat insulating material 27 and placing the wire mesh 30 on the spacer, the same applies. Can be applied.
[0015]
With reference to FIG. 2, the piping of the transport pipe 25 with respect to each room 6 on the first floor in the building 1 will be described. The transport pipe 25 penetrates the base portion 28 and the hard heat insulating material 27 (see FIG. 1) from the discharge port 23 of the boiler 22 to the side corresponding to a certain room 6 from the outside, and corresponds to the one room 6. After being piped while meandering at the part to be pierced, it passes through the base portion 28 and the hard heat insulating material 27 at the boundary between the one room 6 and the other room 6 and corresponds to the next room 6. After being piped while meandering in a part, it passes through the base portion 28 and the hard heat insulating material 27 at the boundary between the adjacent one room 6 and the next adjacent room 6, and further adjacent one room 6, pipes meandering at the part corresponding to each room 6, and the base part 28 and the hard heat insulating material 27 are penetrated to the outside from the part corresponding to the last room 6. As a result, the intake port 24 of the boiler 22 is reached. In the portion corresponding to each room 6, in order to prevent thermal deterioration of the vegetables, the transport pipe 25 is not piped to a part for storing vegetables in the kitchen. In addition, the transport pipe 25 is piped so that the intervals between the meandering transport pipes 25 are equalized in living parts such as living rooms, dining rooms, etc. The whole can be heated at a uniform temperature.
