【０００１】
【発明の属する技術分野】
本発明は、家屋の床及び壁等に内蔵され床や壁等を加熱又は冷却して屋内の冷暖房を行う床・壁面冷暖房ユニット、及びそれを用いた家屋の冷暖房構造、並びに家屋の冷暖房構造の施工方法に関するものである。
【０００２】
【従来の技術】
近年、温水が流れる温水管と、熱媒体が注入されたヒートパイプと、を有し、温水管を流れる温水の熱をヒートパイプへ伝達し床の暖房を行う床・壁面冷暖房ユニットが開発されている。
従来の床・壁面冷暖房ユニットとしては、韓国実用新案１７０４０２号公報（以下、イ号公報という）に「パネルを横切り配置された温水管と、蛇行状に形成され所定部で温水管と点溶接されたヒートパイプと、を備えた温水オンドルパネル」が開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら上記従来の床・壁面冷暖房ユニットにおいては、以下のような課題を有していた。
（１）イ号公報に開示の温水オンドルパネルでは、ヒートパイプが蛇行状に形成され所定部で温水管と点溶接されているので、温水管の熱をヒートパイプに伝達するために必要な温水管とヒートパイプとの接触面積が小さく、温水管からヒートパイプへの伝熱効率が低くヒートパイプからの放熱量が小さいという課題を有していた。
（２）そのため、ヒートパイプからの放熱量を補うために温水管を流れる温水の温度を高めなくてはならず、温水を温めるために過剰なボイラ等の設備負荷及びエネルギーを要するという課題を有していた。
【０００４】
本発明は上記従来の課題を解決するもので、伝熱効率に優れるとともに断熱性に優れ、また、ボイラ等の設備負荷が小さく省エネルギー性に優れ、温度斑がなく冷暖房効率に優れ、さらに、施工性と耐久性に優れる床・壁面冷暖房ユニットを提供することを目的とする。
また、本発明は、温度斑のない均一冷房又は暖房による快適性と断熱性の両方に優れるとともに品質の安定性に優れる家屋の冷暖房構造を提供することを目的とする。
さらに、本発明は、作業工程を極めて簡略化でき作業工数を削減し工期を大幅に短縮することができるとともに品質の安定性に優れる家屋の冷暖房構造の施工方法を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記従来の課題を解決するために本発明の床・壁面冷暖房ユニット及び家屋の冷暖房構造並びにその施工方法は、以下の構成を有している。
【０００６】
本発明の請求項１に記載の床・壁面冷暖房ユニットは、管状の熱供給体と、（ａ）前記熱供給体に面接触され接触面で前記熱供給体と熱交換を行う熱授受部と、放吸熱部と、を備えたヒートパイプ、又は、（ｂ）前記熱供給体の内部に挿通固定され前記熱供給体の内部の熱媒体と面接触で熱交換を行う熱授受部と、放吸熱部と、を備えたヒートパイプと、前記ヒートパイプの背面に配設された断熱体と、を備え、前記断熱体がポリプロピレン等の合成樹脂製で下面が開口する略直方体状に形成された上層断熱体と、上部が前記上層断熱体の開口部に嵌装され独立気泡を有する下層断熱体と、を備えた構成を有している。
この構成により、以下のような作用が得られる。
（１）ヒートパイプの熱授受部が熱供給体と面接触しているので、接触面積が広く、熱供給体から供給される熱のヒートパイプへの伝熱効率に優れる。
（２）熱供給体の熱がヒートパイプに伝達されるので、熱供給体を床や壁の全面に配置する必要がなく、熱供給体の全長を短くすることができる。従って、熱供給体として温水や冷水等の液体が流れる通液部を用いた場合には、液体の流量を少なくすることができ、温水や冷水等を得るための光熱費の削減と、ボイラ、温水循環ポンプ、温水分配機等の設備負荷及びエネルギーを削減することができる。また、熱供給体としてシーズヒータ等の発熱体を用いた場合には、発熱体を加熱するためのエネルギーを削減することができる。
（３）熱供給体として液体の流れる通液部を用いた場合には、液体の流量を少なくすることができるので、暖房始動時等のボイラ等の稼働時間を短くすることができ、所望する冷暖房温度が短時間で得られ快適性に優れる。
（４）ヒートパイプと熱供給体とは面接触しているだけなので、構造が簡単で耐久性に優れる。
（５）熱授受部が熱供給体の内部で挿通固定されると、熱供給体の外表面の形状に関わらず、熱授受部と熱供給体とを面接触させることができ自在性に優れる。
（６）熱授受部が熱供給体の内部で挿通固定されると、熱供給体内部の温水等の液状熱媒体と熱授受部が直接熱交換するので、熱効率に優れる。
（７）断熱体を背面に有しているので、熱供給体やヒートパイプからの熱の背面への流出を防止するので、熱効率に優れるとともに省エネルギー性に優れる。また、遮音性にも優れる。
（８）断熱体を機械的強度の高い上層断熱体と発泡性が高く断熱性の高い下層断熱体とを組み合わせた構造としているので、上層断熱体で熱供給体やヒートパイプを支持するとともに下層断熱体による優れた断熱効果や遮音効果が得られる。
【０００７】
ここで、熱供給体としては、内部にボイラ等で加熱された温水や冷水等の液状熱媒体が流れる通液部や、シーズヒータ等の発熱体挿入孔部を備えたものが用いられるが、通液部は、熱容量の大きな液体を用いていれば冷め難く温度制御が容易であるとともに、電気製品等に障害を与える電磁波の発生がないので好ましく用いられる。
なお、熱供給体の材質としては、銅製，ステンレス製，アルミニウム製，マグネシウム製，チタン製等の金属製や、ポリブテン製，架橋ポリエチレン製等の合成樹脂製等が用いられ管状に形成される。
家屋に配設される熱供給体は、四半間（約０．３１ｍ）、半間（約０．６１ｍ），１間（約１．８２ｍ）程度のものからそれ以上の長さのものまで所定長さに形成される。また、通液部の外形形状は、設置場所に応じて、略円形状，略楕円形状、略三角状，略四角形状等の多角形状等、それらを組み合わせた不定形状等や、それらの一部に溝部や突起等を形成したもの等種々の形状のものを用いることができる。
【０００８】
ヒートパイプとしては、銅製，ステンレス製，アルミニウム製，マグネシウム製，チタン製等の金属製や、ポリブテン製，架橋ポリエチレン製等の合成樹脂製等で管状に形成される。
ヒートパイプの形状としては、ループ状、略蛇腹状、略Ｌ字状、略Ｕ字状、略矩形状等種々の形状のものを用いることができる。また、薄型の板状や筒状等の中空密閉容器状に形成された本体内に隔壁等によって仕切られて略蛇腹状やループ状等に形成されたものも用いることができる。
【０００９】
ヒートパイプの内径としては、０．１〜１０ｍｍ、好ましくは１〜６ｍｍ、より好ましくは２〜４ｍｍとされる。内径が２〜４ｍｍの場合は、ヒートパイプに注入される後述の熱媒体の蒸発と凝縮を適正にすることができ、気液の移動速度が大きく伝熱効率に優れるため好ましい。１〜２ｍｍの場合はヒートパイプの断面積が小さくなり熱の輸送量が小さくなる傾向がみられ、４〜６ｍｍの場合は毛細管現象が働き難くなり気液の移動速度が小さくなる傾向がみられる。０．１〜１ｍｍの場合は、熱の輸送量が小さくなるとともにヒートパイプ内の減圧や熱媒体の注入が困難になりヒートパイプの製造が困難になる傾向がみられ、６〜１０ｍｍの場合は、さらに気液の移動速度が小さくなり伝熱効率が低下する傾向がみられるため好ましくない。特に、０．１ｍｍより小さくなるか１０ｍｍより大きくなると、これらの傾向が著しくなるためいずれも好ましくない。
【００１０】
ヒートパイプの熱授受部を熱供給体に面接触させて固定するため、ヒートパイプの熱授受部は、溶接，ろう付け，接着，溶着等の接合手段によって熱供給体に固定される。また、熱供給体に溝部を形成してそこに熱授受部を装着し、バンド等で緊締したりクリップ等で圧接して固定することもできる。熱授受部に溶接，ろう付け等で接合可能な板状体を接合し、その板状体を熱供給体に溶接，圧接等によって固定することもできる。熱授受部と熱供給体との接触面積を大きくするためである。なお、熱授受部と熱供給体とを緊締したり圧接して固定する場合は、接触面にシリコングリスや熱硬化性接着剤等を介在させると接触面積がより広がるため好ましい。
また、熱供給体の上面とヒートパイプの上端面とが面一になるように熱供給体にヒートパイプを固定すると、床材や壁材等を安定にして熱供給体及びヒートパイプの上に配設できるので好ましい。
【００１１】
なお、ヒートパイプは、家屋の冷暖房構造に応じて適宜選択して、熱供給体の１面又は複数面に配設することができる。複数面に配設された場合、ヒートパイプは熱供給体を軸に対称、又は千鳥状等の非対称に配設することができ、壁面や床面の形状や構造等によっては、各方向に配設されたヒートパイプの数を相違させることもできる。これにより、加熱するのが好ましくない書庫やテレビ等が配置される箇所にはヒートパイプを配設しない等の設計をすることができ、自由度に優れる。
【００１２】
熱供給体の内部で挿通固定されたヒートパイプの端部は、ヒートパイプ内部の通液部で固定されていてもよいし、ヒートパイプを完全に貫通してヒートパイプ外部で固定されていてもよい。
【００１３】
ヒートパイプに注入される熱媒体としては、フロンＨＣＨＣ−１４１ｂや１４２ｂ等のフロン系溶剤、メタノール、エタノール、プロパノール、アセトン、ベンゼン、メチルエチルケトン、アンモニア、エーテル等の揮発性を有する媒体が用いられ、使用する温度に応じて適宜選択することができる。なお、熱媒体の沸騰開始温度を低下させて熱伝達効率を向上させるためヒートパイプ内は減圧され、端部は溶接，接着等で蓋部が固定されて封止される。
【００１４】
ここで、ヒートパイプに封入される熱媒体の量は、ヒートパイプの内容積に対し、３０〜７０ｖｏｌ％好ましくは４０〜６０ｖｏｌ％とされる。４０〜６０％の場合は、過熱現象が発生せず、また伝熱に必要な気泡の量を確保することができ好ましい。４０ｖｏｌ％より少なくなるにつれ過熱現象が発生し易くなる傾向がみられ、６０ｖｏｌ％より多くなるにつれ気泡の量が不足し伝熱効率が低下する傾向がみられるため、いずれも好ましくない。特に、３５ｖｏｌ％より少なくなるか７０ｖｏｌ％より多くなると、これらの傾向が著しくなるため、いずれも好ましくない。
【００１５】
減圧されたヒートパイプ内の真空度は、１．３〜１．３×１０−４Ｐａ、好ましくは１．３×１０−１〜１．３×１０−２Ｐａとされる。１．３×１０−１〜１．３×１０−２Ｐａの場合は、良好な気相部の移動速度が得られ伝熱効率が優れる。１．３×１０−１Ｐａより真空度が低くなるにつれ気相部の移動が起こり難く伝熱効率が低下する傾向がみられ、１．３×１０−２Ｐａより真空度が高くなるにつれ減圧時間が長くなり作業性が低下する傾向がみられるとともに、ヒートパイプの肉厚が薄い等の場合に潰れ易くなる傾向がみられるため好ましくない。特に、１．３Ｐａより真空度が低くなるか１．３×１０−４Ｐａより真空度が高くなるとこれらの傾向が著しくなるため、いずれも好ましくない。
【００１６】
断熱体としては、グラスウール，ロックウール等の無機繊維系、ウレタンフォーム，発泡ポリスチレン等の合成樹脂系、木質繊維系等の繊維や独立気泡内に空気等の気体を含有するものが用いられる。
【００１７】
本発明の請求項２に記載の床・壁面冷暖房ユニットは、管状の熱供給体と、（ａ）前記熱供給体に面接触され接触面で前記熱供給体と熱交換を行う熱授受部と、放吸熱部と、を備えたヒートパイプ、又は、（ｂ）前記熱供給体の内部に挿通固定され前記熱供給体の内部の熱媒体と面接触で熱交換を行う熱授受部と、放吸熱部と、を備えたヒートパイプと、前記ヒートパイプの背面に配設された断熱体と、前記断熱体に内蔵され前記熱供給体や前記ヒートパイプを支持する補強部材と、を備えた構成を有している。
この構成により、請求項１に記載の作用に加え、以下のような作用が得られる。
（１）断熱体の変形を防止することができるとともに床面や壁面からの荷重から熱供給体とヒートパイプの熱授受部との接合部を保護することができるので耐久性に優れる。
【００１８】
補強部材は、ポリプロピレンやＡＢＳ等の合成樹脂製で成形することができる。

（３）ヒートパイプと熱供給体とを各々製造することができるので、各々の加工が容易で生産性に優れるとともに品質の安定性に優れる。
【００２０】
ここで、嵌合凹部としては、深さがヒートパイプの外径よりも大きく形成されたものが用いられ、熱供給体に形成された溝部や熱供給体から突設された突起状のものが用いられる。また、熱供給体の長手方向に連続して形成されているものや、熱授受部が配設される場所に断続して形成されているものが用いられる。
また、ヒートパイプを嵌合凹部に嵌合し、さらに溶接，ろう付け等で固定することもできる。機械的強度を向上させるとともに接触面積をさらに大きくするためである。
また、嵌合凹部に嵌合した熱授受部の表面に合成樹脂発泡体等の断熱体を充填して熱授受部を断熱体で埋設すると、熱授受部と熱供給体との熱効率が高まるため好ましい。
【００２１】
請求項４に記載の発明は、請求項１乃至３の内いずれか１に記載の床・壁面冷暖房ユニットであって、前記断熱体が、上面の所定部に前記熱供給体及び／又は前記ヒートパイプを係止する係止固定部を備えた構成を有している。

【００２３】
本発明の請求項５に記載の発明は、請求項４に記載の床・壁面冷暖房ユニットであって、前記係止固定部が、前記断熱体の上面に複数突設された支持体の上端に軸着固定された構成を有している。
この構成により、請求項４で得られる作用に加え、以下のような作用が得られる。
（１）断熱体上の所望の位置に熱供給体やヒートパイプを係止できるので自在性に優れる。
【００２４】

【００２５】
ここで、連結凸部や連結凹部としては、略三角状や略四角状等の多角形状や略円状等やこれらを組み合わせた形状等、種々の形状のものが用いられる。また、連結凸部の基部が狭く端部を広く形成し、連結凹部はそれを嵌入できる形状に形成すると、一旦係止されたものが容易に外れ難く、振動等によるずれだけでなく引張にも抗し耐久性が増すので好ましい。
【００２６】
本発明の請求項７に記載の発明は、請求項１乃至６の内いずれか１に記載の床・壁面冷暖房ユニットであって、前記熱供給体及び／又は前記ヒートパイプの背面及び／又は前面に密接する放熱体を備えた構成を有している。
この構成により、請求項１乃至６の内いずれか１で得られる作用に加え、以下のような作用が得られる。
（１）放熱体が熱供給体やヒートパイプの直上部以外にも熱を拡散させて伝達させるので、温度分布を均一にすることができ温度ムラがなく快適性に優れる。
【００２７】

（２）熱供給体嵌装部とヒートパイプ嵌装部が、熱供給体とヒートパイプから放射された熱を輻射・反射させるので、床面や壁面への伝熱効率に優れる。
【００２９】
ここで、熱供給体嵌装部とヒートパイプ嵌装部は、熱供給体やヒートパイプの外径よりも深く形成され、熱供給体やヒートパイプの上端面が、放熱体の上端面と面一又はそれより低くなるように形成される。
また、熱供給体嵌装部やヒートパイプ嵌装部の形状は、熱供給体やヒートパイプの放吸熱部の形状に応じて形成される。なお、ヒートパイプの放吸熱部の形状が略Ｕ字状の場合は、略Ｕ字状の他、略半長円状や略半楕円状に形成することもでき、ヒートパイプの放吸熱部の形状が略矩形状の場合は、略矩形状の他、略方形状に形成することもできる。なお、ヒートパイプ嵌装部や熱供給体嵌装部にヒートパイプや熱供給体を嵌装した後、ヒートパイプ嵌装部等の上面に平板状やアルミニウム箔等の箔状等の補助放熱体を配設固定して、補助放熱体とヒートパイプ嵌装部等の間にヒートパイプや熱供給体を介装すると好ましい。放熱体の温度分布を均一にするためである。なお、補助放熱体は接着剤や粘着剤等で放熱体上に固定することもできる。

図１及び図２において、１は実施の形態１の床・壁面冷暖房ユニット、２は銅，ステンレス，アルミニウム等の金属製等で形成され断面が略方形状に形成された熱供給体、３は熱供給体２の長手方向と略平行に形成され内部を温水や冷水等が流れる断面が略円形状の通液部、４は熱供給体２の両側面に長手方向と略平行に連続して形成され熱授受部６（後述する）の外径寸法より深い凹状に形成された嵌合凹部、５は銅，ステンレス，アルミニウム等の金属製やポリブテン，架橋ポリエチレン等の合成樹脂製等でループ状に形成されて熱供給体２の両側部に配設されたヒートパイプ、６は嵌合凹部４に嵌合固定され熱供給体２の側部と面接触するヒートパイプ５の熱授受部、７は熱供給体２の側方に略矩形状に張り出し上面が熱供給体２の上面と面一になるように熱授受部６寄りの所定部で上方に屈曲して形成されたヒートパイプ５の放吸熱部、８は略矩形状で放吸熱部７の外側に湾曲して形成され上面が熱供給体２の上面と面一になるように熱授受部６寄りの所定部で上方に屈曲して形成されたヒートパイプ５の放吸熱部である。
図３において、９はヒートパイプ５に注入されたメチルアルコール，エチルアルコール，フロンＨＣＨＣ１４１ｂや１４２ｂ等の熱媒体、９ａは熱媒体９の液相部、９ｂは熱媒体９の液相部９ａが蒸発した蒸気泡からなり飽和蒸気圧で液相部９ａと平衡状態にある気相部である。液相部９ａと気相部９ｂはヒートパイプ５内でランダムに分布している。
【００４０】
以上のように構成された実施の形態１の床・壁面冷暖房ユニットについて、以下その動作を説明する。
暖房用の場合は、床・壁面冷暖房ユニット１が床下面や壁面に埋設され通液部３が各該ユニット１間で連結され、両端部の該ユニット１はボイラ（図示せず）等と接続される。次いで、熱供給体２の通液部３内に熱媒体９の沸騰開始温度以上に加熱された温水等を流す。温水等によって加熱された熱供給体２は、嵌合凹部４に嵌合されたヒートパイプ５の熱授受部６を加熱する。加熱されたヒートパイプ５は封入された熱媒体９を加熱する。沸騰開始温度以上に加熱された熱媒体９は蒸発して蒸気泡を生じ、体積膨張により平衡状態が崩れ液相部９ａと気相部９ｂの移動が起こる。気相部９ｂは放吸熱部７，８で熱を放出し蒸気泡が凝縮され体積が縮小されるとともに低温液化する。体積が縮小された放吸熱部７，８の気相部９ｂに向けた新たな気相部９ｂの移動によって熱が熱授受部６から放吸熱部７，８に伝達される。温水等によって熱供給体２から放出される熱、及びヒートパイプ５の放吸熱部７，８から放出される熱によって暖房が行われる。
冷房用の場合は、熱供給体２の通液部３内に熱媒体９の沸騰開始温度以下に冷却された冷水等を流し、嵌合凹部４に嵌合されたヒートパイプ５の熱授受部６を冷却する。すると上述の暖房運転の場合とは逆に、熱が放吸熱部７，８から熱授受部６に伝達される。冷水等によって冷却された熱供給体２、及びヒートパイプ５の放吸熱部７，８で吸収された熱によって冷房が行われる。
【００４１】
以上のように実施の形態１の床・壁面冷暖房ユニットは構成されているので、以下のような作用が得られる。
（１）ヒートパイプの熱授受部が熱供給体と面接触しているので、接触面積が広く、熱供給体から供給される熱のヒートパイプへの伝熱効率に優れる。
（２）熱供給体の熱がヒートパイプに伝達されるので、熱供給体を床や壁の全面に配置する必要がなく、熱供給体の全長を短くすることができる。従って、熱供給体に流す液体の流量を少なくすることができ、温水や冷水等を得るための光熱費の削減と、ボイラ、温水循環ポンプ、温水分配機等の設備負荷及びエネルギーを削減することができる。
（３）熱供給体に流す液体の流量を少なくすることができるので、暖房始動時等のボイラ等の稼働時間を短くすることができ、所望する冷暖房温度が短時間で得られ快適性に優れる。
（４）ヒートパイプと熱供給体とは面接触しているだけなので、構造が簡単で耐久性に優れる。
（５）熱供給体の上面とヒートパイプの上面とが面一になるように熱供給体にヒートパイプが固定されているので、床材や壁材等を安定に熱供給体及びヒートパイプの上に配設できる。
（６）嵌合凹部を備えているので、ヒートパイプと熱供給体との接触面積が増大し、伝熱効率に優れる。
（７）ヒートパイプを熱供給体に形成された嵌合凹部に嵌合させれば、ヒートパイプと熱供給体とが密接されるので生産性に優れる。

なお、ヒートパイプ１３の熱授受部１４と面接触する熱供給体１１の所定部を凹状に陥没させ、ここに熱授受部１４を固定することができる。これにより、熱授受部１４と熱供給体１１との接触面積を広くすることができ、簡単な構造で熱供給体からヒートパイプへの伝熱効率を高めることができる。

（５）熱供給体嵌装部とヒートパイプ嵌装部が、熱供給体とヒートパイプから放射された熱を反射させるので、床面や壁面への伝熱効率に優れる。
【００４８】
なお、本実施の形態においては、断熱体５４が上層断熱体５５と下層断熱体５７とが積層された構造について説明したが、積層構造とせずに一体型としたり、発泡ポリスチレン製等の断熱体（下層断熱体）だけを用いる場合もある。
また、放熱体５１を断熱体５４上に配設しない場合もある。この場合は、収納凹部５６が、熱供給体１１やヒートパイプ１３の係止固定部となる。また、この場合も、積層構造とせずに一体型としたり、発泡ポリスチレン製等の断熱体（下層断熱体）だけを用いることができる。
【００４９】
次に、以上のように構成された実施の形態３の床・壁面冷暖房ユニットを用いた床面の冷暖房構造について、図面を参照しながら説明する。
図７は実施の形態３の床・壁面冷暖房ユニットを用いた床面の冷暖房構造を示す要部平面図であり、図８はその要部断面図である。なお、実施の形態３で説明したものと同様のものは、同じ符号を付して説明を省略する。

【００５０】
以上のように実施の形態３の家屋の冷暖房構造は構成されているので、以下のような作用が得られる。
（１）断熱体を大引の上に備えているので、熱供給体やヒートパイプからの熱の流出を防止し、熱効率に優れるとともに省エネルギー性に優れる。また、遮音性にも優れる。
（２）放熱体が熱供給体やヒートパイプの直上部以外にも熱を拡散させて床板に伝達させるので、床板の温度分布を均一にすることができ温度ムラがなく快適性に優れる。

【００５１】
次に、家屋の冷暖房構造の施工方法について、図面を参照しながら説明する。
床・壁面冷暖房ユニットの施工方法は、図７、図８に示すように、まず根太７２ａ，７２ｂに沿って大引７１の上に床・壁面冷暖房ユニット５０，５０ａ，５０ｂの下層断熱体５７を嵌装した上層断熱体５５の収納凹部５６が連通するように敷設する。次に、敷設された上層断熱体５５上に放熱体５１を敷設する。次いで、床・壁面冷暖房ユニット５０，５０ａ，５０ｂの熱供給体１２同士を管継手７３で接続して熱供給体１２，ヒートパイプ１３が放熱体５１の熱供給体嵌装部５２及びヒートパイプ嵌装部５３に嵌装されるように放熱体５１上に配設する。同様にして、根太７２ｂ，７２ｃ間にも床・壁面冷暖房ユニット５０ｃ，５０ｄ，５０ｅを配設する（ユニット配設工程）。
次いで、配管系を形成するために、床・壁面冷暖房ユニット５０ａ，５０ｄにエルボ型継手７４を接続し、エルボ型継手７４，７４間に接続用配管７５を接続する。その際、接続用配管７５の下部の根太７２ｂに接続用配管７５を配設することができる凹部を形成し、凹部に接続用配管７５を配設する。根太７２ｂの機械的強度の低下を防止するため、凹部の形成された根太７２ａの下面側に鋼板等の補強用部材（図示しない）をボルト等で固着する。また、接続用配管７５を土台の上に立設された柱（図示しない）の近傍に配設するときは、必要に応じて、柱の一部を削ってその部分に接続用配管７５を配設する場合もある。その場合も同様に、柱の一部に鋼板等で形成された補強用部材をボルト等で固着して機械的強度の低下を防止する。また、柱の背面に接続用配管７５を配設する場合には、グラスウール等の断熱体を接続用配管７５に被覆して接続用配管７５を流れる温水や冷水等の温度が変動するのを抑制すると好ましい。
このように継手を用いて床・壁面冷暖房ユニットのループを形成し、さらにそのループにボイラ、温水循環ポンプ、温水分配機等の温水加熱循環手段（図示しない）や冷水循環手段を接続する（配管工程）。
次いで、床・壁面冷暖房ユニットの上面に根太７２間に床板７６を架設することにより床材を配設する（床壁材配設工程）。
【００５２】
以上のように、実施の形態３における家屋の冷暖房構造の施工方法は構成されているので、以下のような作用が得られる。
（１）大引や根太等の床支持部材の間に、定型化された床・壁面冷暖房ユニットを敷き詰めて配設した後に床材又は壁材を配設するだけなので、作業工程を極めて簡略化でき作業工数を削減することができる。

（３）床・壁面冷暖房ユニットが根太間の間隔に合わせて作成されているので、根太間に嵌め込んでいくだけで断熱体や熱供給体等の配置ができ、品質の安定性に優れる。
【００５３】

７７は発泡ポリウレタン等の合成樹脂製で形成された断熱体、７８は断熱体７７に内蔵されポリプロピレンやＡＢＳ等の合成樹脂製で成形され放熱体５１を支持する補強部材である。
実施の形態４が実施の形態３と異なる点は、断熱体７７が上層断熱体と下層断熱体を有する積層構造ではない点と、断熱体７７に補強部材７８が内蔵され放熱体５１（熱供給体１１やヒートパイプ１３）を支持している点である。これにより、断熱体７７の変形を防止することができるとともに床板７６からの荷重から熱供給体１２とヒートパイプ１３の熱授受部１４との接合部を保護することができるので耐久性に優れる。
なお、本実施の形態では断熱体７７に補強部材７８が内蔵された場合について説明したが、発泡ポリスチレン等の剛性を有する断熱体の場合には補強部材を内蔵しなくてもよい。

施工方法は、図１０、図１１に示すように、まず、スラブ８９の上に下層断熱体８７を嵌装した上層断熱体８２を配設する。その際、連結凹部８６に連結凸部８５を係止していく。壁８８の近傍に配設された上層断熱体８２の側面と壁８８の間には緩衝体９０を介挿しておく。スラブ８９の上に上層断熱体８２及び下層断熱体８３を配設したら、次に、係止固定部８４にヒートパイプ１３を係止していく（ユニット配設工程）。
次いで、熱供給体１１の両端部には、実施の形態３で説明したのと同様にストレート型やベンド型の継手を接続して熱供給体１１（床・壁面冷暖房ユニット５０）のループを形成する（配管工程）。
ループを形成し終えたら、次に、ヒートパイプ１３の上面に接して溶接金網（金属メッシュ）からなる放熱体９１を配設する。次いで、放熱体９１の上方と下方のかぶりが略同じになるようにコンクリート９１ａを敷設する（床壁材配設工程）。コンクリート硬化後、必要に応じて、フローリング，畳，カーペット等のシート，石材等を敷設することができる。

図１４において、１００ｂは実施の形態８における家屋の冷暖房構造、１０１ａは床板１０１の上面に熱供給体１１，ヒートパイプ１３を嵌装できる大きさと深さに形成された嵌装凹部である。嵌装凹部１０１ａは、熱供給体１１とヒートパイプ１３を嵌装して床板１０１の上面と熱供給体１１，ヒートパイプ１３の上面とを面一のフラット状に形成している。
以上のように構成された実施の形態８における家屋の冷暖房構造が実施の形態６と異なる点は、床材１０１の上面に嵌装凹部１０１ａが形成され、熱供給体１１，ヒートパイプ１３を嵌装している点である。
【００６７】
以上のように実施の形態８における家屋の冷暖房構造は構成されているので、実施の形態６に記載の作用に加え、以下のような作用が得られる。
（１）既設の床面や壁面に形成された嵌装凹部に、床・壁面冷暖房ユニットの熱供給体及びヒートパイプを嵌装して床面や壁面をフラット状に形成できるので、その上面に配設された床材や壁材の厚み分だけしか床面や壁面の厚みが増加しないため、施工後の違和感が少なく快適性に優れる。
【００６８】
なお、本実施の形態においては、床・壁面冷暖房ユニットが放熱体を備えていない場合について説明したが、実施の形態６で説明したのと同様に、アルミニウム製等の薄板等で形成された放熱体を床材１０３の下面に配設する場合もある。また、嵌装凹部を大きく形成してヒートパイプ１３や熱供給体１１の背面に発泡ポリスチレン等の断熱体を配設することもできる。これにより、熱の背面への流出を防止することができ、熱効率に優れるとともに省エネルギー性に優れる。
【００６９】
次に、実施の形態８における家屋の冷暖房構造について、その施工方法を、図面を参照しながら以下説明する。
家屋の冷暖房構造の施工方法は、図１４に示すように、まず既設の床板１０１の上面の所定の位置に嵌装凹部１０１ａを切削等により形成する。嵌装凹部１０１ａは熱供給体１１とヒートパイプ１３とを嵌装できる大きさと深さに形成するとともに、必要に応じて、熱供給体１１間を接続する継手や接続用配管（図示しない）を嵌装するものも形成する（嵌装凹部形成工程）。
次いで、形成された嵌装凹部１０１ａに熱供給体１１とヒートパイプ１３とを嵌装し床・壁面冷暖房ユニットを配設する（ユニット嵌装工程）。
次いで、実施の形態６で説明したのと同様に配管工程と床壁材配設工程とを行う。なお、配管工程において、継手や接続用配管を、必要に応じて形成した嵌装凹部に嵌装することもできる。
【００７０】
以上のように実施の形態８における家屋の冷暖房構造の施工方法は構成されているので、実施の形態６に記載の作用に加え、以下のような作用が得られる。
（１）嵌装凹部形成工程を有しているので、既設の床面に形成された嵌装凹部に、床・壁面冷暖房ユニットの熱供給体及びヒートパイプを嵌装して床面をフラット状に形成できる。そのため、床壁材配設工程で配設される床材や壁材は底部がフラット状の標準のものを用いることができ施工性に優れるとともに、配設された床材の厚み分だけしか床面の厚みが増加せず、施工後の違和感が少なく快適性に優れた家屋の冷暖房構造が得られる。
【００７１】
以上、床・壁面冷暖房ユニットを用いた床面の冷暖房構造及びその施工方法について説明したが、壁面の冷暖房構造及びその施工方法についても床面とほぼ同様である。
図１５は、床・壁面冷暖房ユニットを用いた壁面の暖房構造の他の施工例を示す概略図である。
１１０は基礎部（図示しない）の上面に載上・接続された土台、１１１は桁、１１２は柱や間柱（いずれも図示しない）の側面に鋲，ボルト等の固定部材や接着剤，粘着テープ等で固定された床・壁面冷暖房ユニットの断熱体、１１３は断熱体１１２に保持され土台１１０付近に横設された床・壁面冷暖房ユニットの熱供給体、１１４は略蛇腹状に形成され所定部が熱供給体１１３に固着され断熱体１１２に保持されて垂設されたヒートパイプである。
以上のように壁面の暖房構造は構成されているので、熱供給体１１３に固着されたヒートパイプの熱授受部で発生した気相部が上昇し易く暖房効率に優れる。
なお、壁面の冷房構造の場合には、熱供給体１１３を桁１１１近くに横設しヒートパイプ１１４を吊設するようにすると、液相部が下降し易く冷房効率に優れる。また、熱供給体１１３を流れる冷水等の液状熱媒体で冷された空気が下降し床面付近を冷却するので、快適性に優れる。

[0002]
[Prior art]
In recent years, floor / wall heating / cooling units have been developed that have a hot water pipe through which hot water flows and a heat pipe into which a heat medium is injected, and transmit the heat of the hot water flowing through the hot water pipe to the heat pipe to heat the floor. Yes.
As a conventional floor / wall heating / cooling unit, Korean Utility Model No. 170402 (hereinafter referred to as “A”) describes “a hot water pipe arranged transversely to a panel, and a spot-welded hot water pipe formed in a serpentine shape. And a hot water ondol panel provided with a heat pipe.
[0003]
[Problems to be solved by the invention]
However, the conventional floor / wall surface heating / cooling unit has the following problems.
(1) In the hot water ondol panel disclosed in Gazette No. 1, since the heat pipe is formed in a meandering shape and is spot-welded to the hot water pipe at a predetermined portion, the hot water necessary for transferring the heat of the hot water pipe to the heat pipe There was a problem that the contact area between the pipe and the heat pipe was small, the heat transfer efficiency from the hot water pipe to the heat pipe was low, and the amount of heat released from the heat pipe was small.
(2) For this reason, the temperature of the hot water flowing through the hot water pipe must be increased in order to compensate for the amount of heat released from the heat pipe, and there is a problem that an excessive equipment load and energy such as a boiler are required to warm the hot water. Was.
[0004]
The present invention solves the above-mentioned conventional problems, is excellent in heat transfer efficiency and heat insulation, is small in equipment load such as boilers, is excellent in energy saving, has no temperature spots, is excellent in air conditioning efficiency, and further has workability. The purpose is to provide a floor / wall air conditioning unit with excellent durability.
Another object of the present invention is to provide a cooling / heating structure for a house that is excellent in both comfort and heat insulation by uniform cooling or heating without temperature spots and excellent in quality stability.
Furthermore, an object of the present invention is to provide a method for constructing a heating / cooling structure for a house that can greatly simplify the work process, reduce the number of work steps, greatly shorten the work period, and is excellent in quality stability.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned conventional problems, the floor / wall surface air conditioning unit, the air conditioning structure of a house, and the construction method thereof have the following configurations.
[0006]
The floor / wall surface heating and cooling unit according to claim 1 of the present invention includes a tubular heat supply body,(A)A heat pipe comprising: a heat transfer section that is in surface contact with the heat supply body and exchanges heat with the heat supply body at a contact surface; and a heat release and heat absorption sectionOr (b) a heat pipe provided with a heat transfer section that is inserted and fixed inside the heat supply body and performs heat exchange with a heat medium inside the heat supply body in surface contact, and a heat dissipation heat absorption section, A heat insulator disposed on the back surface of the heat pipe, and an upper layer heat insulator formed in a substantially rectangular parallelepiped shape having a lower surface opened, the heat insulator being made of a synthetic resin such as polypropylene, and the upper portion being the upper layer heat insulator A lower-layer insulation body that is fitted in the opening of the substrate and has closed cells,It has the composition provided with.
With this configuration, the following effects can be obtained.
(1) Since the heat transfer section of the heat pipe is in surface contact with the heat supply body, the contact area is wide and heat transfer efficiency of heat supplied from the heat supply body to the heat pipe is excellent.
(2) Since the heat of the heat supply body is transmitted to the heat pipe, it is not necessary to arrange the heat supply body on the entire surface of the floor or wall, and the overall length of the heat supply body can be shortened. Therefore, when a liquid passing part through which a liquid such as hot water or cold water flows is used as a heat supply body, the flow rate of the liquid can be reduced, and a reduction in utility costs for obtaining hot water or cold water, Equipment load and energy such as hot water circulation pump and hot water distributor can be reduced. Further, when a heating element such as a sheathed heater is used as the heat supply body, energy for heating the heating element can be reduced.
(3) When a liquid passing portion through which a liquid flows is used as the heat supply body, the flow rate of the liquid can be reduced, so that the operation time of a boiler or the like at the time of heating start can be shortened and desired. Air conditioning temperature can be obtained in a short time, and comfort is excellent.
(4) Since the heat pipe and the heat supply body are only in surface contact, the structure is simple and the durability is excellent.
(5) When the heat transfer section is inserted and fixed inside the heat supply body, the heat transfer section and the heat supply body can be brought into surface contact regardless of the shape of the outer surface of the heat supply body, and the flexibility is excellent. .
(6) When the heat transfer section is inserted and fixed inside the heat supply body, the liquid heat medium such as hot water in the heat supply body and the heat transfer section directly exchange heat, so that the heat efficiency is excellent.
(7) Since the heat insulator is provided on the back surface, the outflow of heat from the heat supply body and the heat pipe to the back surface is prevented, so that the heat efficiency is excellent and the energy saving property is also excellent. In addition, the sound insulation is excellent.
(8) Since the heat insulator has a structure in which an upper heat insulator having high mechanical strength and a lower heat insulator having high foamability and high heat insulation are combined, the heat insulator and the heat pipe are supported by the upper heat insulator and the lower layer. Excellent heat insulation effect and sound insulation effect by the heat insulator can be obtained.
[0007]
Here, as the heat supply body, a liquid passage part through which a liquid heat medium such as hot water or cold water heated by a boiler or the like flows, or a heating element insertion hole part such as a sheathed heater is used. If a liquid having a large heat capacity is used, the liquid passing portion is preferably used because it is difficult to cool and temperature control is easy, and there is no generation of electromagnetic waves that impede electrical products.
In addition, as a material of the heat supply body, a metal such as copper, stainless steel, aluminum, magnesium or titanium, or a synthetic resin such as polybutene or cross-linked polyethylene is used, and is formed into a tubular shape.
The heat supply body installed in the house has a predetermined length from a quarter (about 0.31 m), a half (about 0.61 m), and a one (about 1.82 m) to a longer length. Formed. In addition, the outer shape of the liquid passing part may be an approximately circular shape, a substantially elliptical shape, a polygonal shape such as a substantially triangular shape, a substantially rectangular shape, etc., an indefinite shape combining them, or a part of them depending on the installation location. Various shapes such as those having grooves, protrusions, etc. formed thereon can be used.
[0008]
The heat pipe is formed into a tubular shape made of metal such as copper, stainless steel, aluminum, magnesium, titanium, or synthetic resin such as polybutene or cross-linked polyethylene.
As the shape of the heat pipe, various shapes such as a loop shape, a substantially bellows shape, a substantially L shape, a substantially U shape, and a substantially rectangular shape can be used. Moreover, what was partitioned off by the partition etc. in the main body formed in the hollow airtight container shape, such as a thin plate shape and a cylinder shape, and what was formed in the substantially bellows shape, the loop shape, etc. can also be used.
[0009]
The inner diameter of the heat pipe is 0.1 to 10 mm, preferably 1 to 6 mm, and more preferably 2 to 4 mm. When the inner diameter is 2 to 4 mm, evaporation and condensation of a heat medium, which will be described later, injected into the heat pipe can be made appropriate, the gas-liquid moving speed is large, and heat transfer efficiency is excellent, which is preferable. In the case of 1 to 2 mm, there is a tendency that the cross-sectional area of the heat pipe is small and the amount of heat transport is small, and in the case of 4 to 6 mm, the capillary phenomenon is difficult to work and the gas-liquid moving speed tends to be small. . In the case of 0.1 to 1 mm, the amount of heat transport becomes small, and it tends to be difficult to reduce the pressure in the heat pipe and to inject the heat medium, making it difficult to manufacture the heat pipe. Furthermore, the gas-liquid moving speed is further decreased, and the heat transfer efficiency tends to decrease, which is not preferable. In particular, when it is smaller than 0.1 mm or larger than 10 mm, these tendencies become remarkable, and therefore, neither is preferable.
[0010]
In order to fix the heat transfer portion of the heat pipe in surface contact with the heat supply body, the heat transfer portion of the heat pipe is fixed to the heat supply body by joining means such as welding, brazing, adhesion, welding or the like. It is also possible to form a groove in the heat supply body and attach a heat transfer portion to the groove, and fasten it with a band or the like, or press and fix it with a clip or the like. A plate-like body that can be joined by welding, brazing, or the like can be joined to the heat transfer section, and the plate-like body can be fixed to the heat supply body by welding, pressure welding, or the like. This is to increase the contact area between the heat transfer section and the heat supply body. When the heat transfer section and the heat supply body are fastened or fixed in pressure contact, it is preferable that silicon grease, a thermosetting adhesive, or the like is interposed on the contact surface because the contact area further increases.
In addition, when the heat pipe is fixed to the heat supply body so that the upper surface of the heat supply body and the upper end surface of the heat pipe are flush with each other, the flooring and wall materials are stabilized on the heat supply body and the heat pipe. Since it can arrange | position, it is preferable.
[0011]
In addition, a heat pipe can be suitably selected according to the air-conditioning structure of a house, and can be arrange | positioned on the 1st surface or multiple surfaces of a heat supply body. When arranged on multiple surfaces, the heat pipe can be arranged symmetrically with respect to the heat supply body as an axis, or asymmetrically such as a staggered shape, and arranged in each direction depending on the shape and structure of the wall surface and floor surface. It is also possible to vary the number of installed heat pipes. As a result, it is possible to design such that a heat pipe is not provided at a place where a library, a television, or the like where heating is not preferable is provided, and the degree of freedom is excellent.
[0012]
The end of the heat pipe inserted and fixed inside the heat supply body may be fixed at the liquid passage inside the heat pipe, or it may be completely fixed through the heat pipe and outside the heat pipe. Good.
[0013]
As the heat medium injected into the heat pipe, chlorofluorocarbon solvents such as Freon HCHC-141b and 142b, and volatile media such as methanol, ethanol, propanol, acetone, benzene, methyl ethyl ketone, ammonia, and ether are used and used. It can select suitably according to the temperature to perform. In order to improve the heat transfer efficiency by lowering the boiling start temperature of the heat medium, the inside of the heat pipe is depressurized, and the end portion is sealed with a lid portion fixed by welding, adhesion or the like.
[0014]
Here, the amount of the heat medium enclosed in the heat pipe is 30 to 70 vol%, preferably 40 to 60 vol%, with respect to the internal volume of the heat pipe. In the case of 40 to 60%, an overheating phenomenon does not occur, and the amount of bubbles necessary for heat transfer can be secured, which is preferable. Since the tendency to become overheated easily is seen as it becomes less than 40 vol%, the amount of bubbles tends to be insufficient and the heat transfer efficiency tends to be lowered as it exceeds 60 vol%. In particular, when the amount is less than 35 vol% or more than 70 vol%, these tendencies become remarkable, so that neither is preferable.
[0015]
The degree of vacuum in the decompressed heat pipe is 1.3 to 1.3 × 10-4Pa, preferably 1.3 × 10-1~ 1.3 × 10-2Pa. 1.3 × 10-1~ 1.3 × 10-2In the case of Pa, a good moving speed of the gas phase part is obtained and the heat transfer efficiency is excellent. 1.3 × 10-1As the degree of vacuum becomes lower than Pa, the movement of the gas phase portion hardly occurs, and the heat transfer efficiency tends to decrease, and 1.3 × 10 6 is observed.-2As the degree of vacuum becomes higher than Pa, the decompression time becomes longer and the workability tends to decrease, and when the thickness of the heat pipe is thin, it tends to be crushed, which is not preferable. In particular, the degree of vacuum is lower than 1.3 Pa or 1.3 × 10-4When the degree of vacuum becomes higher than Pa, these tendencies become remarkable, so that neither is preferable.
[0016]
As the heat insulator, inorganic fiber such as glass wool and rock wool, synthetic resin such as urethane foam and expanded polystyrene, fiber such as wood fiber, and those containing a gas such as air in closed cells are used.
