Description
【発明の詳細な説明】 （産業上の利用分野） この発明は、床や壁や植木鉢の内部に装填して畜熱材
として使用するものや単独で畜熱容器として使用できる
畜熱ボードとその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a heat storage board that can be used as a heat storage material by being loaded into a floor, a wall, or inside a flowerpot, or can be used alone as a heat storage container, and its manufacture. About the method.
（従来の技術） 省エネルギー等の目的のため、床下や壁等の内部に畜
熱材を埋め込むことが行われる。(Prior Art) For the purpose of energy saving and the like, a heat storage material is buried under a floor or inside a wall.
畜熱材としては、これまで、コンクリートやレンガ等
の顕熱畜熱材が用いられてきた。しかし、最近では、こ
れら顕熱畜熱材よりも体積あたりの畜熱量が大きく、し
かも、一定温度で畜放熱が行える潜熱畜熱材が多用され
るようになってきた。潜熱畜熱材は、固体−液体間、固
体−固体間等の相変化に伴う潜熱を利用するもので、た
とえば、塩化カルシウム６水塩、硫酸ナトリウム10水塩
等の水和塩や、パラフィン類、脂肪酸エステル等が知ら
れている。As a heat storage material, a sensible heat storage material such as concrete or brick has been used. However, recently, latent heat storage heat materials that have a larger storage heat amount per volume than these sensible heat storage heat materials and that can release storage heat at a constant temperature have been increasingly used. Latent heat storage materials utilize latent heat accompanying a phase change between solid-liquid, solid-solid, etc., and include, for example, hydrated salts such as calcium chloride hexahydrate, sodium sulfate decahydrate, and paraffins. , Fatty acid esters and the like are known.
潜熱畜熱材のうち、上記例示のものは、使用時に液体
となるため、従来は密封容器中に封入した状態で使用さ
れることが多かったが、そのようなものでは、下記のよ
うな問題が発生していた。Among the latent heat storage materials, the above-mentioned materials become liquid at the time of use, and thus, in the past, they were often used in a state of being enclosed in a sealed container. However, such materials have the following problems. Had occurred.
潜熱畜熱材は相転移の際に大きな体積変化が生じ、
それが、密封容器の破損につながる。Latent heat storage material undergoes a large volume change during phase transition,
That leads to breakage of the sealed container.
密封容器が破損すると、そこから潜熱畜熱材が多量
に流出し、畜熱作用を失ったり、流出した潜熱畜熱材に
より回りが汚染されたりする。When the sealed container is damaged, a large amount of the latent heat storage heat material flows out therefrom, losing the heat storage effect, or the surroundings are contaminated by the discharged latent heat storage heat material.
（３） 無機水和性の潜熱畜熱材は風解性や吸湿が高い
ため、密封容器が完全に防湿されていないと畜熱作用を
自然に失ってしまう。(3) Since the inorganic hydratable latent heat heat storage material has high efflorescence and moisture absorption, if the sealed container is not completely moisture-proof, the heat storage effect is naturally lost.
そこで、これを解決するため、潜熱畜熱材をカプセル
化する等の方法で多数の潜熱畜熱材粒子にすることが考
えられた。このような潜熱畜熱材粒子では、体積変化は
粒子間の空隙によって吸収されるため、容器が破損した
りすることがなく、たとえ、一つの潜熱畜熱材粒子が破
損されても、それに含まれる潜熱畜熱材は僅かな量であ
るため、その流出が直ちに畜熱作用の損失や回りの汚染
につながることもない。しかも、前述したような無機水
和性の潜熱畜熱材では、その回りをカプセルで覆ってし
まえば、それだけで完全な防湿を行うことができるた
め、密封容器自体も不要となるのである。Therefore, in order to solve this problem, it has been conceived to convert the latent heat storage material into a large number of particles by a method such as encapsulation. In such latent heat storage material particles, since the volume change is absorbed by the voids between the particles, the container is not damaged, and even if one latent heat storage material particle is damaged, it is included in the container. Since only a small amount of latent heat storage material is used, its outflow does not immediately lead to loss of heat storage function and surrounding contamination. Moreover, in the case of the inorganic hydrating latent heat storage material as described above, if the surrounding area is covered with a capsule, complete moisture proofing can be performed by itself, so that the sealed container itself is not required.
したがって、この様な潜熱畜熱材粒子を容器に充填し
て畜熱ボードとする場合、直接、潜熱畜熱材を容器に充
填する場合と比べて容器の強度は弱くすることが出来る
ということが利点となる。Therefore, when the container is filled with such latent heat storage material particles to form a storage heat board, the strength of the container can be reduced as compared with the case where the latent heat storage material is directly charged into the container. It will be an advantage.
（発明が解決しようとする課題） しかし、従来、容器の強度が低いと床や壁に施工する
時に落下させたり物にぶつけたりして容器が破損すると
いう可能性があった。しかして、施工時に持ち運びのた
めには、強度の低い容器を使用する場合、畜熱ボードと
しては容器内で容器に潜熱畜熱材粒子が移動したりしな
い様に容器内に潜熱畜熱材粒子が隙間なく充填されてい
なければならないが、そのため、加熱加圧して潜熱畜熱
材粒子を容器内に押し込むことで畜熱ボードとしての強
度を保っている。(Problems to be Solved by the Invention) However, conventionally, if the strength of the container is low, there is a possibility that the container may be damaged by being dropped or hit against an object when applied to a floor or a wall. However, if a low-strength container is used for transportation during construction, the latent heat storage material particles should be placed in the container so that the latent heat storage material particles do not move to the container inside the container. Must be filled without gaps. Therefore, the strength as a heat storage board is maintained by heating and pressing to push the latent heat storage heat material particles into the container.
第13図は従来の畜熱ボードで、１は容器、２は潜熱畜
熱材粒子、また第14図は、第13図中A1〜A2断面を示し、
容器１内に潜熱畜熱材粒子２が隙間なくつまっており端
部まで固化している。Figure 13 is a conventional heat storage board, 1 container, 2 latent heat storage material particles, also FIG. 14 shows a thirteenth figure A 1 to A 2 cross,
The latent heat storage material particles 2 are tightly packed in the container 1 and solidified to the end.
この様な畜熱ボードを例えば第15図に示すように、端
部から床に落下させると端部も中央部と同じ様に固くな

大きいと変形してしまい、端部は局部的な変形が大きく
なり、変形部３を生じて容器１は破損し、第16図に示す
様な状態となる。なお、第16図中４は容器破損箇所を示
す。When such a heat storage board is dropped from the end to the floor, for example, as shown in Fig. 15, the end is also hardened in the same manner as the center, so there is no place to absorb the shock, If it is large, it will be deformed, and the end will be locally deformed to a large extent, resulting in a deformed portion 3 and the container 1 will be damaged, resulting in the state shown in FIG. In addition, 4 in FIG. 16 indicates a damaged portion of the container.
また、端を物に当てた状態も同じ様に局部的には大き
く容器が変形し、同様の状態となるといったことが従来
例の欠点として上げられる。A disadvantage of the prior art is that the state in which the end is brought into contact with the object is also large locally locally, and the container is deformed to the same state.
しかして、破損すると、潜熱畜熱材粒子２が容器１外
にこぼれてしまい、所定の畜熱量を確保できなくなる。
また、変形したボードは厚くなり施工が難しいといった
課題があった。Thus, if broken, the latent heat storage material particles 2 spill out of the container 1, and it becomes impossible to secure a predetermined storage heat amount.
In addition, there is a problem that the deformed board becomes thick and difficult to construct.
本発明は上記のことに鑑み提案されたもので、その目

衝撃に対して容器が破損せず、変形も修復可能な畜熱ボ
ードおよびその製造方法を提供することにある。The present invention has been proposed in view of the above, and it is an object of the present invention to provide a heat storage device capable of repairing deformation even if a low-strength container is used without the container being damaged by a drop or an impact. A board and a method for manufacturing the board.

記目的を達成している。(Means for Solving the Problems) A heat storage board according to the present invention is a heat storage board formed by filling a container with latent heat storage heat material particles and molding under heat and pressure, in a region of a solidified portion and a region of an unsolidified portion. The above object is achieved by forming

するようにしている。In addition, during production, the latent heat storage material particles impregnated with or absorbed by the latent heat storage material are filled in a container and heated and pressurized. The unsolidified portion and the solidified portion are formed by lowering the pressure or by decreasing the pressure of the non-solidified portion as compared with the pressure of the solidified portion.

合、その修復を可能としている。(Operation) The above-mentioned structure is provided, and an unsolidified portion is provided, so that it is positively deformed when dropped or impacted, thereby preventing damage. Also, in this case, it acts to absorb the impact to some extent, and since it is in an unsolidified state, it can be repaired when deformed.
（実施例） 以下、図面に沿って本発明の実施例を説明する。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the heat storage board made by heating and pressurizing, a solidified portion B and an unsolidified portion C6 are formed.

帰させることも可能である。That is, as described above, for example, if the center portion is a solidified portion B and the end portion is an unsolidified portion C, as shown in FIG. 4, when dropped from the end to the floor, the collision portion is deformed and deformed. A part 3 is generated, but the latent heat storage heat material 2 is not bonded to each other, and the latent heat storage heat material 2 and the container 1 are not bonded to each other. Is in an imperfect state, that is, it is not solidified.
Is easily moved, so that the entire unsolidified portion C is not deformed and the container 1 is not locally deformed or damaged. (See FIG. 5) When the solidified portion B and the non-solidified portion C are formed in the container 1, since the drop impact becomes a problem particularly at the corner portion, as shown in FIG. The solidified portion C may be used. Similarly, as shown in FIG. 7, the length of the container 1 is unsolidified portion C, and as shown in FIG.
The effect is the same. Since the unsolidified portion C has a low filling density and has a gap (space) between the latent heat storage material particles 2, it also has a function of absorbing a drop impact in that space. In addition, since the unsolidified portion C is capable of moving the latent heat storage material particles 2, the container 1 deformed by hand can be returned to the original shape.

に加熱温度を下げれば可能である。Latent heat storage heat material particles 2 by impregnating or absorbing the latent heat storage heat material
Is manufactured, the latent heat storage heat material adheres around the latent heat storage heat material particles 2. When the latent heat storage medium particles 2 are put into the container 1 and heated, the latent heat storage medium adhered around the latent heat storage medium particles 2 is melted, and the latent heat storage medium particles 2 and the container 1 and the latent heat storage medium particles are melted. It is in a state of being attached between the two, and can be solidified if cooled as it is. Therefore, in order to create an unsolidified portion, it is possible to lower the heating temperature so that the latent heat storage material attached around the latent heat storage material particles 2 does not melt.
また、十分加熱したとしても加圧しなければ潜熱畜熱
材粒子２相互の接着力は十分でなく、小さい力で潜熱畜
熱材粒子２は移動させることが出来る。Moreover, even if the heating is performed sufficiently, the adhesive force between the latent heat storage material particles 2 is not sufficient unless the pressure is applied, and the latent heat storage material particles 2 can be moved with a small force.

に隙間を持たせた未固化部Ｃ″と加圧大として固化部
Ｂ″とした畜熱ボードで、これは加熱を小さくして潜熱
畜熱材粒子２間の接着はないように構成されている。FIG. 11 shows a heat storage board having an unsolidified portion C "in which a gap is provided between the latent heat storage heat material particles 2 by reducing the pressure and a solidified portion B" in which the pressure is increased. It is configured to be small so that there is no adhesion between the latent heat storage material particles 2.
