Description

本発明は、床暖房装置において、熱源機と床暖房用温水マット間を結ぶ導管材に関するものである。   The present invention relates to a conduit material connecting a heat source machine and a floor heating hot water mat in a floor heating apparatus.

図８に従来の床暖房システムを示す。この図８において、符号の１００は熱源機、１０１は床暖房用温水マット、１０２は放熱器、１０３、１０４は熱源機１００と温水マット１０１、エアコン１０２を結ぶ温水循環用の導管材、１０５は外壁、１０６は床スラブであって、前記導管材１０３、１０４は図９に示すように、２本の樹脂チューブ２、３の外にアルミニュウム製テープ６を一部オーバーラップさせて螺旋状に巻きつけて束ねた所謂ペアチューブと称され、、このペアチューブ４は、断面円形又は楕円形状のＣＤ管９の内に挿通されている。   FIG. 8 shows a conventional floor heating system. 8, reference numeral 100 is a heat source machine, 101 is a hot water mat for floor heating, 102 is a radiator, 103 and 104 are conduit materials for circulating hot water connecting the heat source machine 100 and the hot water mat 101 and the air conditioner 102, and 105 The outer wall 106 is a floor slab, and the conduit members 103 and 104 are spirally wound by partially overlapping the aluminum tape 6 outside the two resin tubes 2 and 3, as shown in FIG. It is called a so-called pair tube that is attached and bundled, and this pair tube 4 is inserted into a CD tube 9 having a circular or elliptical cross section.

しかし、この従来の導管材には、次のような欠点がある。
１．アルミニュウムテープ６は、２本のチューブ２、３を束ねるだけの目的であるため
、断熱効果がない。
２．配管後のＣＤ管９内には、空気が自由に入り込むため、ＣＤ管９は、厳しい冷気の
通り道となって、ペアチューブ４自体が直接冷却され、熱損失が非常に大きい。
３．ＣＤ管９内にペアチューブ４を挿通するときに、ＣＤ管９の内側の山にペアチュー
ブ４の先端が引っ掛かって挿通しにくい。
４．施工上、ＣＤ管９の外径はできるだけ小径が望ましいことから、常法でペアチュー
ブ４の外に断熱層を形成した場合、どうしてもペアチューブ４の外径が太くなり、従
来のこの種床暖房用ＣＤ管９内に通しにくくなる。 However, this conventional conduit material has the following drawbacks.
1. Since the aluminum tape 6 is only for the purpose of bundling the two tubes 2 and 3, there is no heat insulation effect.
2. Since air freely enters the CD tube 9 after piping, the CD tube 9 becomes a path for severe cold air, the pair tube 4 itself is directly cooled, and heat loss is very large.
3. When the pair tube 4 is inserted into the CD tube 9, it is difficult to insert the pair tube 4 because the tip of the pair tube 4 is caught on the inner mountain of the CD tube 9.
4). Since the outer diameter of the CD tube 9 is desirable to be as small as possible in the construction, when the heat insulation layer is formed outside the pair tube 4 by a conventional method, the outer diameter of the pair tube 4 inevitably increases, and this conventional seed bed It becomes difficult to pass through the CD tube 9 for heating.

その他のこの種導管材であって、断熱構造を有するものとしては、次のようなものが公知である。
特開２００５−２０１５６１号公報 この公知例は、「温水が流通する往き管３及び戻り管５と、往き管３及び戻り管５を被覆する断熱被覆管７とを有していて、断熱被覆管７は平行２端辺を有する平板状の１枚の断熱部材を用いて成形され、往き管３及び戻り管５を管軸を揃えて収容する中空筒状部１７、１８と、中空筒状部１７、１８を管端部から管軸に沿って分離可能に接続する接続部１９とを有する温水配管」であって、ペアチューブと称される導管の一種である。 Other types of conduit materials that have a heat insulating structure are known as follows.
JP, 2005-201561, A This publicly known example has "the forward pipe 3 and the return pipe 5 through which warm water flows, and the heat insulation coated pipe 7 which covers the forward pipe 3 and the return pipe 5, 7 is a hollow cylindrical portion formed by using a flat plate-shaped heat insulating member having two parallel edges, and accommodates the forward tube 3 and the return tube 5 with the tube axes aligned, and a hollow cylindrical portion. 17 and 18 is a hot water pipe having a connecting portion 19 that detachably connects from the pipe end portion along the pipe axis, and is a kind of conduit called a pair tube.

しかし、この公知例の場合、鞘管と組み合わせたものでないことから、鞘管に対する挿入しやすさ、と云った課題の解決手段は示されていないばかりか、２本の管３、５に１枚の断熱部材を巻きつけているため、この巻きつけには手間がかかる。また、２本の管３、５は、束ねられていないため、配管作業時に小さな力がかかると離れることがあり、実用には不適である。   However, in the case of this known example, since it is not combined with the sheath tube, a solution to the problem of ease of insertion into the sheath tube is not shown, and the two tubes 3, 5 have 1 Since the heat insulating member is wound, this winding takes time. Moreover, since the two pipes 3 and 5 are not bundled, they may be separated when a small force is applied during the piping work, which is unsuitable for practical use.

特開２００５−２０１５６０号公報 この公知例は、「温水が流通する往き管３及び戻り管５と、往き管３及び戻り管５の管軸を揃えて収容した中空筒状部１７、１８と、中空筒状部１７、１８を管軸に沿って管端部から分離可能に接続する接続部１９と、断熱性を備え可撓性に優れた外皮管７とを有した構成の温水配管１」であって、これもペアチューブと称される導管の一種である。JP, 2005-151560, A This publicly known example is "The hollow pipe parts 17 and 18 which accommodated the tube axis of return pipe 3 and return pipe 5 through which warm water distributes, and the pipe axis of forward pipe 3 and return pipe 5, and A hot water pipe 1 having a configuration including a connecting part 19 that connects the hollow cylindrical parts 17 and 18 along the pipe axis so as to be separable from the pipe end part, and a sheath pipe 7 that has heat insulation and excellent flexibility " And this is also a kind of conduit called a pair tube.

しかし、この温水配管１の場合、ＣＤ管内に挿入しているが、往きと戻り管３、５は断熱部材で別々に被覆されており、製造にコストがかかる。また、管３、５をＣＤ管内に挿入するときは、ＣＤ管の内径山に引っ掛かって挿入がしにくいという欠点がある。
特開２００２−３２３１９４号公報 特開平１０−３１８４４５号公報 However, in the case of this hot water pipe 1, it is inserted into the CD pipe, but the forward and return pipes 3 and 5 are separately covered with a heat insulating member, and the manufacturing costs are high. Further, when the tubes 3 and 5 are inserted into the CD tube, there is a drawback that the tube 3 or 5 is caught by the inner diameter crest of the CD tube and is difficult to insert.

In the paired tube, the heat insulating effect in the paired tube is enhanced by forming the heat insulating layer inside the aluminum tape that bundles the two tubes, and heat loss can be reduced. In the experimental example, when 1 mm thick foamed polyethylene is used as a heat insulating material, the heat loss is 15 to 15 times that of a conventional product just wound with aluminum tape.
30% improvement.
2. A heat insulating air layer was uniformly formed between the CD tube and the paired tube, and further, the improvement of heat loss by several percent could be recognized by the formation of the clogging and the heat insulating paint layer.
