ところで、潜熱蓄熱材は温度に応じた相変化による体積変化があり、凝固時には体積が減少する。そのため、特許文献１及び２に示されているように、蓄熱材を容器に封入して床材の空洞に収容していると、凝固時に潜熱蓄熱材の体積が減少したとき、その容器と床材の空洞部内壁面との間に隙間ができてしまい、この隙間によって熱移動が妨げられて潜熱蓄熱材の応答性が低下するという問題が生じる。   By the way, the latent heat storage material has a volume change due to a phase change corresponding to the temperature, and the volume decreases during solidification. Therefore, as shown in Patent Documents 1 and 2, when the heat storage material is enclosed in a container and accommodated in a floor material cavity, when the volume of the latent heat storage material decreases during solidification, the container and the floor There arises a problem that a gap is formed between the inner wall surface of the hollow portion of the material, and the heat transfer is hindered by this gap and the response of the latent heat storage material is lowered.

また、容器がポリプロピレン等の剛性があるものである場合、その容器内で潜熱蓄熱材との間に空隙ができるので、やはり同様の問題が生じる。   In addition, when the container is rigid such as polypropylene, a gap is formed between the container and the latent heat storage material, so that the same problem occurs.

本発明は斯かる諸点に鑑みてなされたもので、その目的は、蓄熱床材における潜熱蓄熱材の配置構造に工夫を凝らすことにより、蓄熱床材の隙間による熱移動の妨げをなくして潜熱蓄熱材の応答性を向上させるようにすることにある。   The present invention has been made in view of the above points, and its purpose is to devise the arrangement structure of the latent heat storage material in the heat storage floor material, thereby eliminating the heat transfer hindrance due to the gap of the heat storage floor material and latent heat storage.

以下、本発明の実施形態を図面に基づいて詳細に説明する。以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものでは全くない。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or its application.

図１及び図２は本発明の実施形態に係る潜熱蓄熱床材Ａを示し、この床材Ａは例えば室内の床下地Ｂ（図２参照）の上に施工されるもので、床材本体１を有する。この床材本体１は、例えば幅３０３ｍｍ、長さ１８１８ｍｍ、厚さ１２ｍｍの矩形板状のもので、例えば合板やＭＤＦ、或いは大建工業（株）製の商品名「ダイライト」等の無機質系板材等、通常に床材として用いられる材料が用いられる。   1 and 2 show a latent heat storage floor material A according to an embodiment of the present invention. This floor material A is constructed on, for example, an indoor floor base B (see FIG. 2). Have The flooring main body 1 is, for example, a rectangular plate having a width of 303 mm, a length of 1818 mm, and a thickness of 12 mm. For example, a plywood, MDF, or an inorganic board such as “Dailite” manufactured by Daiken Kogyo Co., Ltd. A material usually used as a flooring material is used.

図３に示すように、床材本体１の下面、つまり施工時に室内空間と反対側の面には、例えば１２（複数）の一定深さ（例えば８ｍｍ）の矩形状の凹部６，６，…が床材本体１の長さ方向及び幅方向に略等間隔に並んで形成されている。これらの凹部６，６，…は、床材本体１の四周縁部及び凹部６，６間に所定幅を残すように形成されており、床材本体１は凹部６以外の位置で後述する蓋材１５と共に切断可能とされている。図３の破線は切断位置Ｌを例示している。   As shown in FIG. 3, on the lower surface of the flooring main body 1, that is, the surface opposite to the indoor space at the time of construction, for example, 12 (plural) rectangular recesses 6, 6,. Are formed side by side at substantially equal intervals in the length direction and the width direction of the flooring main body 1. These recesses 6, 6,... Are formed so as to leave a predetermined width between the four peripheral edges of the floor material body 1 and the recesses 6, 6. The floor material body 1 is a lid described later at a position other than the recess 6. It can be cut together with the material 15. The broken line in FIG. 3 illustrates the cutting position L.

上記各凹部６内にはそれぞれ包袋状容器８が収容されている。この包袋状容器８は、凹部６よりも少し小さい矩形状の大きさで厚さの薄い（例えば８ｍｍ）可撓性のあるパック（袋）であり、例えばアルミニウム等の伝熱材料からなり、その内部には潜熱蓄熱材１１が充填されている。パックに封入されるため、マイクロカプセル化されていない潜熱蓄熱材１１やゲル化された潜熱蓄熱材等も使用することができる。この容器８の伝熱材料としては、アルミニウムの他に例えばポリエチレンやポリオレフィン等を用いることができるが、充填する潜熱蓄熱材１１と反応しないものを用いる必要がある（潜熱蓄熱材１１としてのパラフィンはオレフィン等と反応する）。また、ＰＥＴ及びポリエチレンの複合体にアルミニウムを蒸着したものを用いることができる。   A sachet 8 is accommodated in each of the recesses 6. The bag-like container 8 is a flexible pack (bag) having a rectangular size slightly smaller than the concave portion 6 and a thin thickness (for example, 8 mm), and made of a heat transfer material such as aluminum, The inside is filled with a latent heat storage material 11. Since it is enclosed in the pack, the latent heat storage material 11 which is not microencapsulated, the gelatinized latent heat storage material, or the like can also be used. As the heat transfer material of the container 8, for example, polyethylene or polyolefin can be used in addition to aluminum, but it is necessary to use a material that does not react with the latent heat storage material 11 to be filled (paraffin as the latent heat storage material 11 is Reacts with olefins). Moreover, what vapor-deposited aluminum to the composite of PET and polyethylene can be used.

上記容器８は、上面が床材本体１の凹部６内に該凹部６の内底面６ａと伝熱可能に接着された状態で収容されている。   The container 8 is accommodated in a state in which the upper surface is bonded to the inner bottom surface 6a of the recess 6 so as to be capable of conducting heat transfer in the recess 6 of the flooring main body 1.

上記潜熱蓄熱材１１としては、例えばｎ−オクタデカン、ｎ−ヘキサデカンが主原料のノルマルパラフィンが用いられる。このノルマルパラフィンは、融点が２３〜２８℃のもので、基本的に融点よりも低い温度で固体となり、融点よりも高い温度で液体となる。この潜熱蓄熱材１１としてのノルマルパラフィンは略そのまま容器８としてのアルミニウムパックに詰められて使用され、温度変化に応じて固体・液体と相変化する。ノルマルパラフィンの比重は約０．８である。   As the latent heat storage material 11, for example, normal paraffin whose main raw material is n-octadecane or n-hexadecane is used. This normal paraffin has a melting point of 23 to 28 ° C., basically becomes a solid at a temperature lower than the melting point, and becomes a liquid at a temperature higher than the melting point. The normal paraffin as the latent heat storage material 11 is used by being packed in an aluminum pack as the container 8 as it is, and changes in phase with solid / liquid according to the temperature change. The specific gravity of normal paraffin is about 0.8.

ノルマルパラフィン以外の潜熱蓄熱材１１としては、無機水和塩（塩化カルシウム六水和塩、硫酸ナトリウム十水和塩等）、脂肪酸類（パルミチン酸、ミリスチン酸等）、芳香族炭化水素化合物（ベンゼン、ｐ−キシレン等）、エステル化合物（パルミチン酸イソプロピル、ステアリン酸ブチル等）、アルコール類（ステアリルアルコール等）、ポリアルキレングリコール等を使用することができる。   As the latent heat storage material 11 other than normal paraffin, inorganic hydrate salts (calcium chloride hexahydrate, sodium sulfate decahydrate, etc.), fatty acids (palmitic acid, myristic acid, etc.), aromatic hydrocarbon compounds (benzene) , P-xylene, etc.), ester compounds (isopropyl palmitate, butyl stearate, etc.), alcohols (stearyl alcohol, etc.), polyalkylene glycols, and the like can be used.

さらに、上記各凹部６内には、上記包袋状容器８の下側（凹部６の開口側）にクッション材１３が収容されている。このクッション材１３は、その上側に位置する上記容器８を該容器８の上面が凹部６の内底面６ａに伝熱可能に押し付けられるように付勢するものであり、この実施形態では、例えばウレタン等の発泡樹脂やラテックス系樹脂やゴム系樹脂等の軟質樹脂等からなり厚さが３ｍｍ程度の薄板形状のものが用いられる。   Further, in each of the recesses 6, a cushion material 13 is accommodated on the lower side of the bag-like container 8 (opening side of the recess 6). The cushion material 13 urges the container 8 positioned on the upper side thereof so that the upper surface of the container 8 is pressed against the inner bottom surface 6a of the recess 6 so that heat can be transferred. In this embodiment, for example, urethane For example, a thin plate having a thickness of about 3 mm made of a soft resin such as a foamed resin such as latex resin or rubber resin is used.

尚、クッション材１３は、上記付勢機能があるものであれば、その材料や形状はどのようなものであってもよい。   The cushion material 13 may have any material or shape as long as it has the above-described urging function.

また、プラスチックダンボール、硬質樹脂発泡体等のクッション性のない断熱材と上記クッション性を有する薄板形状のクッション材１３を組み合わせて、該容器８の上面が凹部６の内底面６ａに伝熱可能に押し付けられるように付勢するようにしてもよい。   Further, a heat insulating material having no cushioning property such as plastic corrugated cardboard or hard resin foam and a cushion material 13 having a thin plate shape having the cushioning property are combined so that the upper surface of the container 8 can transfer heat to the inner bottom surface 6a of the recess 6. You may make it bias so that it may be pressed.

そして、床材本体１の下面には、床材本体１と同じ大きさの蓋材１５が床材本体１下面全体に亘り一体的に接着固定されており、この蓋材１５により各凹部６の開口が凹部６内に容器８及びクッション材１３を収容した状態で封閉されている。この蓋材１５は例えばクラフト紙ガラスクロスラミネート板等からなる。   A lid 15 having the same size as the flooring main body 1 is integrally bonded and fixed to the lower surface of the flooring main body 1 over the entire lower surface of the flooring main body 1. The opening is sealed in a state where the container 8 and the cushion material 13 are accommodated in the recess 6. The lid member 15 is made of, for example, a kraft paper glass cloth laminate plate or the like.

したがって、この実施形態においては、潜熱蓄熱床材Ａは床下地Ｂ上に、通常一般の床材と同様にして例えばウレタン系等の接着剤を用いて接着固定されて施工される。   Therefore, in this embodiment, the latent heat storage floor material A is applied and fixed onto the floor base B in the same manner as an ordinary floor material, for example, using an adhesive such as urethane.

その場合、潜熱蓄熱床材Ａは潜熱蓄熱材１１を充填した包袋状容器８が床材本体１の各凹部６内に収容されて一体化されたものであるので、この潜熱蓄熱床材Ａを特別な施工法ではなくて通常の床材と同様の施工法で床下地Ｂ上に施工すればよく、その施工が容易となる。   In this case, since the latent heat storage floor material A is formed by integrating the packaging-like containers 8 filled with the latent heat storage material 11 in the respective recesses 6 of the floor material body 1, the latent heat storage floor material A May be constructed on the floor base B not by a special construction method but by a construction method similar to a normal flooring material, and the construction becomes easy.

また、潜熱蓄熱床材Ａは床材本体１下面の凹部６，６，…の各々に、潜熱蓄熱材１１が充填された伝熱材料からなる可撓性を有する包袋状容器８が収容され、その容器８が凹部６の内底面６ａに接着されかつクッション材１３により上方に付勢されて凹部６の内底面６ａに押し付けられているので、凹部６の内底面６ａと容器８との間に隙間が生じることはない。しかも、容器８内の潜熱蓄熱材１１もクッション材１３により凹部６の内底面６ａに対し伝熱状態に維持される。これらによって容器８内の潜熱蓄熱材１１と床材Ａの表面（上面）との間の熱移動がスムーズに行われ、潜熱蓄熱材１１の応答性を向上させることができる。また、潜熱蓄熱材１１は包袋状容器８内に該容器８の内面に接着されて収容されているので、潜熱蓄熱材１１を容器８に常時密着させて蓄放熱特性をさらに高めることができる。よって、別途の熱源を利用せずとも室内空間の温度を恒温化して省エネルギー性を高めることができる。   Further, the latent heat storage floor material A accommodates a flexible packaging bag 8 made of a heat transfer material filled with the latent heat storage material 11 in each of the recesses 6, 6,. Since the container 8 is bonded to the inner bottom surface 6a of the recess 6 and is urged upward by the cushion material 13 and pressed against the inner bottom surface 6a of the recess 6, the space between the inner bottom surface 6a of the recess 6 and the container 8 is There will be no gaps. Moreover, the latent heat storage material 11 in the container 8 is also maintained in a heat transfer state with respect to the inner bottom surface 6 a of the recess 6 by the cushion material 13. By these, the heat transfer between the latent heat storage material 11 in the container 8 and the surface (upper surface) of the flooring A is performed smoothly, and the responsiveness of the latent heat storage material 11 can be improved. Further, since the latent heat storage material 11 is housed in the bag-like container 8 by being adhered to the inner surface of the container 8, the latent heat storage material 11 can be kept in close contact with the container 8 to further enhance the heat storage and heat dissipation characteristics. . Therefore, the temperature of the indoor space can be kept constant without using a separate heat source, and energy saving can be improved.

さらに、潜熱蓄熱材１１はそのまま包袋状容器８に充填され、マイクロカプセルとする必要がないので、低コストで単位重量当たり大きな潜熱量を見込むことができ、潜熱蓄熱床材Ａを薄くて軽いものとすることができる。   Furthermore, since the latent heat storage material 11 is filled in the sachet-shaped container 8 as it is and does not need to be a microcapsule, a large amount of latent heat per unit weight can be expected at low cost, and the latent heat storage floor material A is thin and light. Can be.

また、上記複数の凹部６，６，…は床材本体１の下面に床材本体１の長さ方向及び幅方向に並んで形成されているので、この凹部６以外の部分で床材Ａの踏み込み強度を確保することができ、使用者が踏んだときの沈み込み等の違和感をなくすことができる。しかも、凹部６以外の部分で床材本体１が切断可能であるので、その切断によって床材Ａを任意の寸法に調整でき、その際に潜熱蓄熱材を破損することもない。   In addition, since the plurality of recesses 6, 6,... Are formed on the lower surface of the flooring body 1 in the length direction and the width direction of the flooring body 1, The stepping strength can be ensured, and an uncomfortable feeling such as depression when the user steps on can be eliminated. And since the flooring main body 1 can be cut | disconnected in parts other than the recessed part 6, the flooring A can be adjusted to arbitrary dimensions by the cutting | disconnection, and a latent heat storage material is not damaged in that case.

次に、具体的に実施した実施例について説明する。   Next, specific examples will be described.

図２に示す構造の潜熱蓄熱床材を作製した。床材本体は厚さ１２ｍｍの尺角サイズの合板であり、その凹部の深さは８ｍｍである（床材本体上面と凹部内底面との厚さは４ｍｍ）。包袋状容器は、ＰＥＴとポリエチレンの複合体にアルミニウムを蒸着したものである。潜熱蓄熱材としてはパラフィン（融点２５℃）を用い、クッション材は厚さ２．５ｍｍのダンプレートを用いた。 Example 1
A latent heat storage floor material having the structure shown in FIG. 2 was produced. The floor material body is a 12 mm thick plywood with a depth of 8 mm, and the depth of the recess is 8 mm (the thickness of the top surface of the floor material body and the bottom surface of the recess is 4 mm). The sachet container is obtained by evaporating aluminum on a composite of PET and polyethylene. Paraffin (melting point: 25 ° C.) was used as the latent heat storage material, and a 2.5 mm thick damper plate was used as the cushion material.

（実施例２）
床材本体は熱伝導率が合板よりも高いＭＤＦであり、その厚さは１２ｍｍで、凹部の深さは８ｍｍである。その他の構成は実施例１と同じである。 (Example 2)
The floor material body is MDF whose thermal conductivity is higher than that of plywood, its thickness is 12 mm, and the depth of the recess is 8 mm. Other configurations are the same as those of the first embodiment.

（比較例１）
実施例１において、クッション材を除いたものである。それ以外は実施例１と同じである。 (Comparative Example 1)
In Example 1, the cushion material is excluded. The rest is the same as in Example 1.

（比較例２）
通常の合板製の床材であり、凹部、その内部の潜熱蓄熱材収容の包袋、クッション材等は設けられていない。 (Comparative Example 2)
It is a normal plywood floor material, and is not provided with a recess, a wrapping bag for accommodating a latent heat storage material therein, a cushion material, and the like.

（寒熱繰り返し試験）
各実施例及び各比較例の各試験体を恒温恒湿槽に入れ、最初に１５℃の試験開始温度で４時間養生した後、（1）１５℃で２時間の保持、（2）その後に２時間かけて４０℃に昇温、（3）この４０℃で２時間保持、（4）その後に２時間かけて２０℃に降温、を複数回繰り返した（図４の「恒温恒湿槽内温度」参照）。 (Cryogenic repetition test)
After putting each test body of each Example and each Comparative Example in a constant temperature and humidity chamber, first curing for 4 hours at a test starting temperature of 15 ° C., (1) holding at 15 ° C. for 2 hours, (2) thereafter The temperature was raised to 40 ° C. over 2 hours, (3) held at 40 ° C. for 2 hours, and then (4) the temperature was lowered to 20 ° C. over 2 hours. Temperature ”).

そして、この各試験体の表面に熱電対を貼り、表面温度を測定した。試験体の裏面（凹部開口側面）と木口面は断熱材で断熱し、熱移動は試験体の表面（床材表面）のみからとなるようにした。   And the thermocouple was affixed on the surface of each test body, and the surface temperature was measured. The back surface (concave opening side surface) and the end surface of the test body were insulated with a heat insulating material, and heat transfer was performed only from the surface of the test body (floor surface).

その試験の結果を図４に示す。この図４を見ると、比較例２は槽内温度と同様の温度変動を示している。また、実施例１、２及び比較例１は比較例２と比較して温度の一定となる部分があり、表面温度の恒温化を確認できた。その恒温化の効果は実施例２、実施例１、比較例１の順で高くなっており、このことから、表面の熱伝導率が高い方が性能が良く、クッション材のない比較例１では、室温を意図する温度帯に保てないことが判る。   The result of the test is shown in FIG. When FIG. 4 is seen, the comparative example 2 has shown the temperature fluctuation | variation similar to the temperature in a tank. Further, Examples 1 and 2 and Comparative Example 1 had a portion where the temperature was constant as compared with Comparative Example 2, and it was confirmed that the surface temperature was kept constant. The effect of the constant temperature is higher in the order of Example 2, Example 1, and Comparative Example 1. From this, the higher the thermal conductivity of the surface, the better the performance, and in Comparative Example 1 without the cushioning material. It can be seen that room temperature cannot be maintained in the intended temperature range.

本発明は、通常の床材と同様に施工できかつ室内を恒温化できる潜熱蓄熱床材が得られるので、極めて有用であり、産業上の利用可能性が高い。   INDUSTRIAL APPLICABILITY Since the present invention can provide a latent heat storage floor material that can be constructed in the same manner as a normal floor material and can keep the room at a constant temperature, it is extremely useful and has high industrial applicability.
