Description

【０００１】
【発明の属する技術分野】
本発明は床暖房用パネルに関するものである。
【０００２】
【従来の技術】
熱媒循環用パイプを設けたパネルユニットの複数を縦横に隣接させて所望の広さの床暖房用パネルを構成する従来の方法では、各パネルユニットへの熱媒の供給は、並列供給部材としてのヘッダーを用いて各パネルユニット毎に並列に行っている。例えば、出願人の先の出願、特願平８−２４２８５５号の願書に添付した明細書及び図面に示すものでは、各パネルユニットは４隅に切欠部を形成した正方形の板状体に、蛇行させた熱媒循環用パイプを１経路構成し、その両端を一隅の切欠部に位置させた構成としている。このような構成において、各パネルユニットは、熱媒循環用パイプの両端部が位置する夫々の一隅を対向させて隣接し、それらの切欠部により形成される空間部において、夫々の熱媒循環用パイプの端部を熱源装置に連なる熱媒往き管、熱媒還り管に接続したヘッダーに接続している。
【０００３】
【発明が解決しようとする課題】
このように、複数のパネルユニットを縦横に隣接させて所望の広さに構成する従来の床暖房用パネルでは、熱媒を循環供給する形態が並列に制限されてしまって自由度がなく、このような構成では床下配管のための要素が多くなり、構成が比較的複雑になってしまう。
そこで本発明では、このような課題を解決し、熱媒の循環供給の形態を多様に設定することができる床暖房用パネルを提供することを目的とするものである。
【０００４】
【課題を解決するための手段】
上述した課題を解決するために、本発明では、正方形の板状体の隣接する２隅に切欠部を設けると共に、一方の切欠部から他方の切欠部に至る熱媒循環用パイプを２経路設けて、これら２経路のうち、１経路の熱媒循環用パイプの経路を蛇行させた構成とすると共に、他の経路の熱媒循環用パイプの経路は直線状の構成としたパネルユニットの複数を、切欠部を設けた辺と切欠部を設けていない辺の夫々が一線上となるように縦横方向に隣接させて所望の広さに構成し、向かい合った切欠部により形成される空間部において各経路の熱媒循環用パイプの所定の端部相互間を接続部材により接続すると共に、所定の対を成す端部を熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材に接続して構成する床暖房用パネルを提案する。
【０００５】
また本発明では、上記の床暖房用パネルにおいて、縦横に隣接させたパネルユニットの隣接する４つを１群とし、その中心側に位置する切欠部により構成される空間部において、各切欠部に位置する２経路の熱媒循環用パイプの端部を、熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材に接続すると共に、周囲側に位置する切欠部により構成される空間部において、各切欠部に位置する２経路の熱媒循環用パイプの端部相互間を接続部材により接続し、上記１群を構成する隣接の４つのパネルユニットの熱媒循環用パイプに１群の中心側から並列に熱媒を循環供給可能に構成する床暖房用パネルを提案する。
【０００６】
また本発明では、上記の床暖房用パネルにおいて、縦横に隣接させたパネルユニットの隣接する４つを１群とすると共に、隣接する２組として構成し、１群の中心側に位置する切欠部により構成される空間部において、夫々の組の隣接する切欠部に属する隣接の２経路の熱媒循環用パイプの端部相互間を接続部材により接続すると共に、他の２経路の熱媒循環用パイプの端部の夫々を熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材に接続し、また１群の周囲側に位置する切欠部により構成される空間部において、各切欠部に位置する２経路の熱媒循環用パイプの端部相互間を接続部材により接続し、上記１群を構成する隣接の４つのパネルユニットの熱媒循環用パイプに、上記組毎に、上記１群の中心側から直列に熱媒を循環供給可能に構成する床暖房用パネルを提案する。
【０００７】
また本発明では、上記の床暖房用パネルにおいて、隣接する４つのパネルユニットを１群とし、１群の中心側に位置する切欠部により構成される空間部において、隣接する切欠部に属する隣接の２経路の熱媒循環用パイプの端部相互間を１組を除いて接続部材により接続し、また上記１組の端部の夫々を熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材に接続すると共に、１群の周囲側に位置する切欠部により構成される空間部において、各切欠部に位置する２経路の熱媒循環用パイプの端部相互間を接続部材により接続し、上記１群を構成する隣接の４つのパネルユニットの全ての熱媒循環用パイプに、上記１群の中心側から直列に熱媒を循環供給可能に構成する床暖房用パネルを提案する。
【０００８】
また本発明では、上記の床暖房用パネルにおいて、一列に隣接している複数のパネルユニットを１群とし、群の中間部では、隣接する切欠部により構成される空間部において、隣接する切欠部に属する隣接の２経路の熱媒循環用パイプの端部相互間と他の２経路の端部相互間を接続部材により接続すると共に、列の他方側で隣接する切欠部により構成される空間部において、各切欠部に位置する２経路の熱媒循環用パイプの端部相互間を接続部材により接続し、１群の一方の端では、切欠部により構成される空間部において、この切欠部に位置する２経路の熱媒循環用パイプの端部の夫々を熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材に接続すると共に、１群の他方の端では、切欠部により構成される空間部において、この切欠部に位置する２経路の熱媒循環用パイプの端部相互間を接続部材により接続し、上記１群を構成する複数のパネルユニットの熱媒循環用パイプに、１群の端側から直列に熱媒を循環供給可能に構成する床暖房用パネルを提案する。
【０００９】
そして本発明では、上記の床暖房用パネルにおいて、供給部材にバルブ機構を構成することを提案する。
【００１０】
以上の本発明によれば、パネルユニットの複数を縦横に隣接させて所望の広さの床暖房用パネルを構成する際、接続部材により接続する熱媒循環用パイプの経路の端部相互と、熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材を接続する上記熱媒循環用パイプの端部の位置を適宜に選択することにより、縦横に隣接させた複数のパネルユニットの各熱媒循環用パイプに対する熱媒の循環供給の形態を、隣接する４つを１群として並列、直列又は直並列として多様な形態として設定することができる。また、このように隣接する４つを１群とする他に、一列に隣接している複数、即ち２つはもとより、３つ以上のパネルユニットを１群として直列に熱媒を循環供給させるように構成することができる。
【００１１】
そして供給部材にバルブ機構を設けて熱媒を供給するパネルユニットを選択することにより、暖房範囲の調節を多様な形態で行うことができる。
【００１２】
本発明では、切欠部を設けた辺が一線上となるパネルユニットの隣接部分では、向かい合った切欠部により形成される空間部において熱媒循環用パイプ相互の接続と、熱媒循環用パイプと熱媒往き管、熱媒還り管との接続を行うことができると共に、切欠部を設けていない辺の夫々が一線上となるパネルユニットの隣接部分では空間部が形成されないので、この空間部から床下空間等に熱が放散することを防ぐことができる。
【００１３】
【発明の実施の形態】
次に本発明の実施の形態を図を参照して説明する。図１〜図３は本発明を適用したパネルユニットＵの実施の形態を概念的に示すもので、図１は平面図、図２、図３は、夫々図１のＡ−Ａ線矢視図、Ｂ−Ｂ線断面図である。これらの図において、符号１は板状体であり、この板状体１は正方形であって、隣接した２隅に切欠部２（２ａ，２ｂ）を設けている。この板状体１は，熱媒、例えば温水を循環させるための熱媒循環用パイプ３を支持するために、一面側に溝４を形成し、熱媒循環用パイプ３をこの溝４に装着して支持する構成としている。
溝４は一方の切欠部２ａから他方の切欠部２ｂに至る２経路を設けて、これらの夫々に熱媒循環用パイプ３を装着しており、従って熱媒循環用パイプ３は２経路構成し、両側の夫々の端部を切欠部２ａ，２ｂに位置させている。
これらの熱媒循環用パイプ３の端部は、図示は省略しているが、後述する接続部材及び供給部材に接続可能とするように切欠部２の面から外側に適宜長突出させる等、接続が容易な構成とする。また図示の通り、この例では、熱媒循環用パイプ３の２経路のうち、切欠部２ａ，２ｂの近い側の経路３ｓは直線状の経路としており、また離れた側の経路３ｗは蛇行させた構成としている。しかしながら、夫々の経路３ｓ，３ｗの経路の形状は適宜に構成することができる。
ここで板状体は、床の荷重を支えることができる材質であれば、木質合板、パーチクルボード、発泡プラスチックス板、またはこれらの複合体等の適宜の材質のものを適用することができる。
熱媒は、上述したように例えば温水であり、この場合、熱媒循環用パイプ３は、例えば架橋ポリエチレン等の、耐圧、耐熱、耐久性に優れた材質のパイプを使用することができる。
また切欠部の形状は、図示のように隅を斜めに切り欠いた形状とする他、隅を直角に切り欠いた形状とする等、適宜である。
また板状体１に熱媒循環用パイプ３を支持する構成は、上記のように溝４に熱媒循環用パイプ３を一面側から装着して支持する構成の他、板状体１内に埋め込んで支持する構成とすることもできる。
【００１４】
以上の構成のパネルユニットＵの複数を、切欠部２ａ，２ｂを設けた辺５ｓと切欠部を設けていない辺５ｗの夫々が一線上となるように縦横方向に隣接させて所望の広さに構成し、向かい合った切欠部により形成される空間部において各経路の熱媒循環用パイプ３の所定の端部相互間を接続部材６により接続すると共に、所定の対を成す端部を熱源装置に連なる熱媒往き管７、熱媒還り管８に接続した供給部材９に接続することにより、熱媒を循環供給可能に構成して、所望の広さの床暖房用パネルを構成することができる。尚、接続部材６と供給部材９の具体例は後述する。
【００１５】
図３には床暖房用パネルを使用して床を構成するための他の要素の例を仮想線で示しており、符号１０はパネルユニットＵの４隅の下側に突設した支持脚、１１は床スラブ、１２は床暖房用パネルの上側に積層するフローリング床等の仕上床材である。この他、例えば仕上床材１２と床暖房パネル間にアルミニウム箔等の熱伝導率の高い材質の層を構成して、熱媒循環用パイプ３からの熱を周囲に拡散することにより床の均熱化を計る等、本発明の床暖房用パネルを使用した床の具体的構成及びその構成方法は適宜である。
【００１６】
次に、本発明のパネルユニットＵを複数縦横に隣接させて構成する床暖房用パネルの具体的形態を図について説明する。
図４は第１の形態を示すもので、この形態は、縦横に隣接させた複数のパネルユニットＵの隣接する４つを１群とする構成である。
図４中の実線は縦横に多数隣接させたパネルユニットＵのうちの着目する隣接した４つのパネルユニットＵ（Ｕ1，Ｕ2，Ｕ3，Ｕ4）を示すもので、右側；左側の夫々のパネルユニットＵ1，Ｕ2；Ｕ3，Ｕ4は切欠部を設けた辺５ｓが図中左側；右側に一線上となるように隣接しており、従ってそれらの切欠部２ａ，２ｂが対向する方向で隣接しており、これらの対向した切欠部２ａ，２ｂにより、パネルユニットＵの１群の中心側に正方形の空間部Ｓが構成されている。一方、図中右側のパネルユニットＵ1，Ｕ2の右側では、隣接するパネルユニットＵと共に、切欠部を設けていない辺５ｗが一線上となっていて、この線状には切欠部による空間部が構成されていない。
【００１７】
上記空間部Ｓ内には熱源装置（図示省略）に連なる熱媒往き管、熱媒還り管（図示省略）に接続した供給部材９、即ち、ヘッダーを配置しており、その熱媒往き側と熱媒還り側を、夫々各切欠部２に位置する２経路の熱媒循環用パイプ３の端部に接続している。即ち、夫々のパネルユニットＵにおいて、夫々経路３ｓ、３ｗの端部を熱媒往き側、熱媒還り側に接続している。
一方、１群の周囲、この場合上下側に位置する夫々のパネルユニットＵの切欠部２ａ，２ｂも、それらと隣接する他の群のパネルユニットＵの切欠部と対向して正方形の空間部Ｓ′が構成されており、この空間部Ｓ′内において各パネルユニットＵの切欠部２に位置する２経路の熱媒循環用パイプ３の各端部相互間を接続部材６により接続している。
従って夫々のパネルユニットＵの熱媒循環用パイプ３の経路３ａ，３ｂは接続部材６により直列に接続されて、それらの両端部が空間部Ｓを構成する切欠部２に位置し、こうして１群を構成する各パネルユニットＵの熱媒循環用パイプ３は、供給部材９に対して並列に接続される。
こうして、この構成では、１群を構成する４つのパネルユニットに、それらの中心側から並列に熱媒を循環供給することができる。この際、供給部材９にバルブ機構を構成すれば、熱媒を供給するパネルユニットＵを選択することができるので、部屋の配置替え、その他の変更条件に応じて、各パネルユニットＵに対する熱媒の供給形態を調節することができる。
【００１８】
次に図５は第２の形態を示すもので、この形態では、複数のパネルユニットを縦横に隣接させる形態及び隣接させた４つを１群とする形態は、図４の構成と同様であるが、熱媒の供給形態を図４のものとは異ならせている。尚、図５では図４の要素と同様な要素には同一の符号を付して重複する説明は省略する。
この構成では、１群の周囲側に位置する空間部Ｓ′内においては図４の構成と同様に各パネルユニットＵの切欠部２に位置する２経路の熱媒循環用パイプ３の各端部相互間を接続部材６により接続して、夫々のパネルユニットＵの熱媒循環用パイプ３の経路３ｓ，３ｗを直列に接続しているが、１群の中心側の空間部Ｓ内においては、図中縦方向に隣接するパネルユニットＵ1，Ｕ2（及びＵ3，Ｕ4）に属する隣接の２経路３ｗ，３ｗの熱媒循環用パイプ３の端部相互間を接続部材６により接続している。
このため図中縦方向に隣接するパネルユニットＵ1，Ｕ2（及びＵ3，Ｕ4）の熱媒循環用パイプ３は直列に接続された状態となり、結局、１群のパネルユニットは、直列に接続されたパネルユニットＵ1，Ｕ2とＵ3，Ｕ4の２組に構成される。そして空間部Ｓには、熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材９を配置し、その熱媒往き側と熱媒還り側に、夫々パネルユニットＵ1，Ｕ2（Ｕ3，Ｕ4）の経路３ｓ，３ｓの端部を接続する。
【００１９】
こうして、この構成では、１群の中心側の空間部Ｓに配置した供給部材９により、上記各組に並列に熱媒を循環供給することができると共に、各組においては、隣接したパネルユニットＵに直列に熱媒を循環供給することができる。
この構成においても供給部材９にバルブ機構を構成すれば、熱媒を供給するパネルユニットＵの組を選択することにより熱媒の供給形態を変更することができる。
【００２０】
ここで、この実施の形態を用いて、接続部材６と供給部材９の具体例を説明する。まず図６は、図５における中心側の空間部Ｓの近傍を拡大し、一部を便宜的に断面表示した平面図、図７は図７のＸ−Ｘ線断面図である。また図６は図６において周囲側、即ち上側に位置する空間部Ｓ′の近傍を拡大して示す平面図である。そして図９〜図１１は接続部材６と供給部材９を構成する要素の正面図である。
【００２１】
この具体例では、接続部材６は、図１０に示すメス部材１３と図９に示すオス部材１４とから構成している。メス部材１３は両端を閉じたプラスチックス製等の筒体１５の両端側の横方向に接続筒部１６を突出させ、夫々の接続筒部１６の先端にフランジ部１７を設けた構成である。またオス部材１４は９０゜曲がったパイプ１８の一方の端側に熱媒循環用パイプ３への嵌入筒部１９を設けると共に、他方の端側にはメス部材１３の接続筒部１６への嵌入筒部２０を設けた構成であり、嵌入筒部１９，２０の夫々には水密的な接続を保持する手段を設けている。即ち、この例では、架橋ポリエチレン等の弾性変形が可能な材質の熱媒循環用パイプ３内に嵌入する嵌入筒部１９は、いわゆる竹の子と称される凹凸部を設けた構成としており、また弾性変形のしにくい材質のメス部材１３の接続筒部１６内に嵌入する嵌入筒部２０は、外周にゴムパッキン２１を装着した構成としている。また嵌入筒部２０の後側には、接続筒部１６のフランジ部１７と当接するフランジ部２２を設けている。
【００２２】
次に供給部材９は、図１１に示すメス部材２３と図９に示すオス部材１４とから構成している。即ち、オス部材１４は接続部材６と供給部材９に兼用する部材である。従って、メス部材２３は、概ね、接続部材６用のメス部材１３と同様な構成であり、筒体１５の両端側の横方向に、オス部材１４の嵌入筒部２０を嵌入させる接続筒部１６を突出させ、夫々の接続筒部１６の先端にフランジ部１７を設けている。そして、このような構成に加えて、メス部材２３は、筒体１５の一端側は閉止せずに熱媒往き管７及び熱媒還り管８への嵌入筒部２４を設けた構成としており、この嵌入筒部２４には、水密的な接続を保持する手段としての竹の子と称される凹凸部を設けている。
【００２３】
以上の構成においては、接続する２つの経路の熱媒循環用パイプ３の夫々の端部にオス部材１４の嵌入筒部１９を嵌入すると共に、夫々の嵌入筒部２０をメス部材１３の接続筒部１６に嵌入することにより、空間部Ｓ、Ｓ′の下方において２つの経路を連通することができる。
また熱媒往き管７又は熱媒還り管８に接続する経路の熱媒循環用パイプ３には、上記と同様にオス部材１４の嵌入筒部１９を嵌入すると共に、夫々の嵌入筒部２０をメス部材２３の接続筒部１６に嵌入し、さらにメス部材２３の嵌入筒部２４を熱媒往き管７又は熱媒還り管８に接続することにより、隣接する２つの経路の熱媒循環用パイプ３と、熱媒往き管７又は熱媒還り管８を、空間部Ｓの下方において供給部材９を介して接続することができる。
尚、図示は省略しているが、オス部材１４とメス部材１３，２３の接続においては、当接したフランジ２２，１７をクリップ等で挟持することにより、水圧による外れを防止することができる。
このような接続により、図５に示すように上述したとおり、１群の中心側の空間部Ｓに配置した供給部材９により、上記各組に並列に熱媒を循環供給することができると共に、各組においては、隣接したパネルユニットＵに直列に熱媒を循環供給することができる。
【００２４】
尚、以上の接続部材６及び供給部材９は、図５に示す形態の他、上述及び後述の他の形態のいずれにも適用できるものである。また接続部材６及び供給部材９は、以上の他、管を接続する適宜の機構を適用できることはいうまでもない。
【００２５】
次に図１２は第３の形態を示すもので、この形態では、複数のパネルユニットを縦横に隣接させる形態及び隣接させた４つを１群とする形態は、図４、図５の構成と同様であるが、熱媒の供給形態をこれらとは異ならせている。尚、図１２においても上図の要素と同様な要素には同一の符号を付して重複する説明は省略する。
この構成では、図５の構成において、供給部材９の熱媒往き側に接続していたパネルユニットＵ1，Ｕ4の経路３ｓ，３ｓの熱媒循環用パイプ３の端部相互間を接続部材６により接続すると共に、供給部材９の熱媒還り側に接続していたパネルユニットＵ2，Ｕ3の経路３ｓ，３ｓの端部には、夫々供給部材９の熱媒往き側、熱媒還り側を接続している。
【００２６】
こうして、この形態では、１群を構成する４つのパネルユニットＵの全ての熱媒循環用パイプ３を直列に構成して、１群の中心側の空間部Ｓから直列に熱媒を循環供給することができる。
【００２７】
次に図１３は第４の形態を示すもので、この形態では、一列に隣接している複数のパネルユニットＵを１群としている。図では後述するように３つのパネルユニットＵを１群としているが、その数は４つ以上でも良い。尚、この図１３においても上記図４〜図１２と同様な要素には同一の符号を付して重複する説明は省略する。
図１３では、上下方向に隣接させた一列の３つのパネルユニットを１群とし、その群を複数並置して所望の広さの床暖房用パネルを構成している。
図に示した４列の群を夫々ａ，ｂ，ｃ，ｄとすると、切欠部２を設けた辺５ｓは、ａ群，ｃ群では右側、ｂ群，ｄ群では左側で一線上に配置しているため、ａ群とｂ群及びｃ群とｄ群の間に、向かい合った切欠部２による空間部Ｓ，Ｓ′が構成され、ｂ群とｃ群の間には空間部Ｓ，Ｓ′が構成されない。
以上の構成において、次にｂ群につき熱媒の循環経路を説明する。
まずｂ群の中間部では、その各切欠部２ａ，２ｂと、列の左側で隣接するａ群の切欠部２ａ，２ｂにより構成される空間部Ｓにおいて、夫々の隣接する切欠部２ａ，２ｂに属する隣接の２経路３ｗ，３ｗと、他の２経路３ｓ，３ｓの夫々の熱媒循環用パイプ３の端部相互間を接続部材６により接続している。そして群の一方の端、即ち図中下端では、切欠部２ｂにより構成される空間部Ｓにおいて、この切欠部２ｂに位置する２経路３ｓ，３ｗの熱媒循環用パイプ３の端部の夫々を熱源装置に連なる熱媒往き管，熱媒還り管（図示省略）に接続した供給部材９に接続している。また群の上端では、空間部Ｓにおいて、切欠部２ａに位置する２経路３ｓ，３ｗの熱媒循環用パイプ３の端部相互間を接続部材６により接続している。
【００２８】
こうして、この形態では、１群を構成する一列の複数のパネルユニットＵの熱媒循環用パイプ３に、１群の端側に接続した供給部材９から直列に熱媒を循環供給することができる。
【００２９】
図１４は、群の中間部の列の左側において隣接する切欠部により構成される空間部Ｓの近傍を拡大して示す平面図の例であり、この図の例では、夫々の隣接する切欠部２ａ，２ｂに属する隣接の２経路３ｗ，３ｗと、他の２経路３ｓ，３ｓの夫々の熱媒循環用パイプ３の端部相互間を、図９に示したオス部材１４と図１０に示したメス部材１３により構成した接続部材６により接続している。
【００３０】
以上の各実施の形態に示すように、本発明では、パネルユニットＵの複数を縦横に隣接させて所望の広さの床暖房用パネルを構成する際、接続部材６により接続する熱媒循環用パイプ３の経路３ｓ，３ｗの端部相互と、熱源装置に連なる熱媒往き管７、熱媒還り管８に接続した供給部材９を接続する上記熱媒循環用パイプ３の経路３ｓ，３ｗの端部の位置を適宜に選択することにより、縦横に隣接させた複数のパネルユニットＵの各熱媒循環用パイプ３に対する熱媒の循環供給の形態を、隣接する４つを１群として並列、直列又は直並列として多様な形態として設定することができる他、一列に隣接している複数、即ち２つはもとより、３つ以上のパネルユニットを１群として直列に熱媒を循環供給させるように構成することができる。
【００３１】
また、以上の実施の形態では説明を省略しているが、供給部材９に適宜のバルブ機構を設けて熱媒を供給するパネルユニットＵを選択可能とすることにより、暖房範囲の調節を多様な形態で行うことができる。
【００３２】
そして本発明では、以上の各実施の形態において、切欠部２ａ，２ｂを設けた辺５ｓが一線上となるパネルユニットＵの隣接部分では、向かい合った切欠部２ａ，２ｂにより形成される空間部Ｓ，Ｓ′において熱媒循環用パイプ３相互の接続と、熱媒循環用パイプ３と熱媒往き管７、熱媒還り管８との接続を行うことができると共に、切欠部２ａ，２ｂを設けていない辺５ｗの夫々が一線上となるパネルユニットの隣接部分では空間部が形成されないので、この空間部から床下空間等に熱が放散することを防ぐことができる。
【００３３】
【発明の効果】
本発明は以上のとおりであるので、次のような効果がある。
ａ．複数のパネルユニットを縦横に隣接させて所望の広さの床暖房用パネルを構成する際、各パネルユニットの熱媒循環用パイプへの熱媒を循環供給の形態が並列に制限されてしまうことがなく、並列はもとより、直列、直並列の形態での熱媒の循環供給が可能であるため、設計の自由度が高い。
ｂ．並列の形態では、熱源装置に連なる熱媒往き管、熱媒還り管に接続した供給部材にバルブ機構を構成することにより、熱媒を供給するパネルユニットを選択することができ、暖房範囲の調節を行うことができる。
ｃ．直列の形態では、供給部材との接続要素を削減することができるので、構成を簡素化することができる。
ｄ．複数のパネルユニットを隣接させた際に形成される開口部を必要最小限とすることができるので、開口部から床下への放熱を低減することができる。

BACKGROUND OF THE INVENTION
The present inventionFloor heating panelIt is about.
[0002]
[Prior art]
In the conventional method of constructing a floor heating panel having a desired width by vertically adjoining a plurality of panel units provided with heat medium circulation pipes, the supply of the heat medium to each panel unit is performed as a parallel supply member. This is done in parallel for each panel unit using the header. For example, in the specification and drawings attached to the applicant's earlier application, Japanese Patent Application No. Hei 8-242855, each panel unit is meandered into a square plate having four notches at the corners. The heat medium circulation pipe is configured as one path, and both ends thereof are positioned at the notches at one corner. In such a configuration, each panel unit is adjacent to each other where both ends of the heat medium circulation pipe are located opposite to each other, and in each space formed by the notches, the respective heat medium circulation pipes are used. The end of the pipe is connected to a header connected to a heat medium forward pipe connected to the heat source device and a heat medium return pipe.
