この発明は 基材中に蓄熱材が分散された蓄熱体に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a heat storage body in which a heat storage material is dispersed in a base material.
住宅において、昼間室温が高い時にはその熱を蓄え、夜
間室温が下がると放熱するという蓄熱建材がある。これ
は、昼間の温度の温度上昇、夜間の温度低下を防ぎ、室
温を常に安定した状態に保ち、快適な生活を提供すると
ともに、省エネルギーにも連がることから、その必要性
が叫ばれている。In houses, there are heat storage building materials that store heat when the room temperature is high during the day and radiate it when the room temperature drops at night. This prevents daytime temperatures from rising and nighttime temperatures from falling, keeps the room temperature stable at all times, provides a comfortable life, and also saves energy, so the necessity of this system has been emphasized. There is.
従来、室内での蓄熱という目的でコンクリート等が用い
られてきたが、単位体積あたりの蓄熱量が少なかった。Conventionally, concrete has been used for the purpose of storing heat indoors, but the amount of heat stored per unit volume was small.
さらに、夏期のように蓄熱しな（でもよい場合にも蓄熱
してしまい、逆効果になってしまうなどの問題があった
。Furthermore, there were problems such as not storing heat like in the summer (even when it would be better to do so, it would store heat, which would have the opposite effect).
このような問題を解決するため、現在、潜熱蓄熱材の使
用がさかんに検討され一部実用化されつつある。In order to solve such problems, the use of latent heat storage materials is currently being actively studied and some are being put into practical use.
潜熱蓄熱材のメリットとしては、単位体積あたりの蓄熱
量が大きく、コンパクトにできること、および、一定温
度で熱の出入りも行えるため、その相転移温度が冬期の
暖房温度より高く、夏期の冷房温度より低いものを選択
すれば、冬期は蓄熱による暖房効果があり、夏期は潜熱
蓄熱せず冷房等の妨げにならないということが挙げられ
る。The advantages of latent heat storage materials are that they have a large amount of heat storage per unit volume, can be made compact, and that heat can be transferred in and out at a constant temperature, so their phase transition temperature is higher than heating temperatures in winter and lower than air conditioning temperatures in summer. If a low value is selected, there will be a heating effect due to heat storage in the winter, and there will be no latent heat storage in the summer, which will not interfere with air conditioning.
住宅の暖房温度レベルで使用する潜熱蓄熱材としては、
無機水和物系と有機系とに大別できる。Latent heat storage materials used at residential heating temperature levels include:
It can be broadly classified into inorganic hydrate type and organic type.
無機水和物系のものは、過冷却や相分離が生じるうえ、
非透湿層で包み込まないと潮解や風解を起こしてしまい
蓄熱効果をなくしてしまうという欠点がある。一方、有
機系、つまり、パラフィン系や油脂系のものは過冷却が
少なく安定で水分に対しても問題がないので、建材中に
分散させる蓄熱材として注目をあつめている。ところが
、この有機系の蓄熱材をそのまま建材などの基材中に分
散させて蓄熱建材を得ても、使用していくうちに建材表
面に蓄熱材が染み出してしまい、蓄熱効果が無くなると
いう欠点があった。Inorganic hydrates not only cause supercooling and phase separation, but also
If it is not wrapped in a moisture-impermeable layer, it has the disadvantage of causing deliquescence and efflorescence, which eliminates the heat storage effect. On the other hand, organic materials, such as paraffin and oil-based materials, are stable with little supercooling and have no problem with moisture, so they are attracting attention as heat storage materials that can be dispersed in building materials. However, even if this organic heat storage material is directly dispersed in a base material such as a building material to obtain a heat storage building material, the disadvantage is that the heat storage material oozes out onto the surface of the building material as it is used, and the heat storage effect is lost. was there.
この発明は、このような事情に鑑みて、基材中に分散さ
れた潜熱蓄熱材が常に基材中に安定して保持され、優れ
た蓄熱効果を安定して得られる蓄熱体を提供することを
目的としている。In view of these circumstances, it is an object of the present invention to provide a heat storage body in which a latent heat storage material dispersed in a base material is always stably retained in the base material, and an excellent heat storage effect can be stably obtained. It is an object.

とする。In order to achieve these objects, the present invention uses an organic latent heat storage material that has a melting point in a low temperature range, and a substance that is compatible with this latent heat storage material and has a melting point in a high temperature range. The gist is a heat storage body formed by impregnating a base material with a mixed molten liquid.

る。FIG. 1 schematically shows one embodiment of a heat storage body according to the present invention. As shown in the figure, the heat storage body of the present invention has an organic latent heat storage material 2 which has a melting point in a low temperature range in the pores of an aggregate 1, and is compatible with this latent heat storage material 2 and has a high temperature A mixed molten liquid of substances 3 having melting points in the range is impregnated, cooled, and solidified through phase separation within the pores. The low temperature range mentioned here generally refers to the operating temperature range of the heat storage body, and the high temperature range refers to a temperature range higher than that. Although the figure is schematic, the latent heat storage material 2 and the substance 3 are actually separated more narrowly.

After that, the substance 3 is removed by holding it at a temperature lower than the melting point of the substance 3 and higher than the melting point of the latent heat storage material 2.
solidify and phase separate. Through this operation, the substance 3 functions as a membrane that confines the molten liquid of the latent heat storage material 2 within the pores of the aggregate 1 and prevents it from leaking. On the other hand, when the aggregate is polyethylene, the polyethylene is heated to a temperature equal to or higher than its softening point and immersed in the melt 4 to cause it to swell and be absorbed. In the case of rubber, it is impregnated by kneading it with the above-mentioned melt using a pressurized knee gun or the like.

とを防止するためである。The uses of this heat storage body A are as follows. That is, as shown in FIG. 3, it is mixed into a slurry of a base material 5 such as gypsum, molded and hardened, and a plate-shaped heat storage building material in which heat storage bodies A are dispersed in the base material can be obtained. This mixing into the heat storage material is generally carried out at a temperature equal to or higher than the melting point of the latent heat storage material. This is because if it is mixed at a temperature below the melting point, when the temperature reaches the melting point or above during use, the heat storage material expands and
This is to prevent the heat storage material from leaking into the base material or from swelling the base material.

It is desirable to use C or lower. The melting point of high melting point substances is 50°C so that they do not melt even in direct sunlight in summer.
As mentioned above, it is preferable to use a temperature of 80° C. or higher.
