Description
本発明は、蓄熱材組成物及び建築物の冷暖房用の蓄熱システムに関し、詳しくは、建造物の冷暖房の蓄熱システムに好適な蓄熱材組成物及びこれを含む建築物の冷暖房用の蓄熱システムに関する。
The present invention relates to a heat storage material composition and a heat storage system for cooling and heating a building, and more particularly, to a heat storage material composition suitable for a heat storage system for cooling and heating a building, and a heat storage system for cooling and heating a building including the same.
従来、液体から固体への相変化時や固体から液体への相変化時に発生又は吸収かする潜熱を利用した潜熱蓄熱材組成物が知られている。潜熱蓄熱材組成物は、例えば、建造物の冷暖房の蓄熱システムに用いられる。
Conventionally, a latent heat storage material composition utilizing latent heat generated or absorbed at the time of a phase change from a liquid to a solid or at the time of a phase change from a solid to a liquid has been known. The latent heat storage material composition is used, for example, in a heat storage system for cooling and heating a building.
潜熱蓄熱材組成物には、一般的に、蓄熱量が大きいこと、所定の温度レベルで作動すること、長期間安定であること、安価であること、毒性がないこと、腐触性がないこと等の特性が要求される。
The latent heat storage material composition generally has a large amount of heat storage, operates at a predetermined temperature level, is stable for a long period of time, is inexpensive, has no toxicity, and has no non-corrosiveness. And other characteristics are required.
上記潜熱蓄熱材組成物が建造物の冷暖房の蓄熱システムに用いられる場合、潜熱蓄熱材組成物は、建造物の冷暖房の一般的な使用温度域である２０℃以上かつ３０℃以下で融解・凝固が生じることが好ましい。具体的には、潜熱蓄熱材組成物は、融解下限温度Ｔｓが２０℃以上かつ融解上限温度Ｔｆが３０℃以下であることが好ましい。ここで、融解下限温度Ｔｓとは、潜熱蓄熱材組成物が融解潜熱を発現する下限温度を意味し、融解上限温度Ｔｆとは、潜熱蓄熱材組成物が融解潜熱を発現する上限温度を意味する。
When the latent heat storage material composition is used in a heat storage system for cooling and heating a building, the latent heat storage material composition melts and solidifies at a temperature of 20 ° C. or more and 30 ° C. or less, which is a general use temperature range for cooling and heating of a building. Preferably occurs. Specifically, the latent heat storage material composition preferably has a lower melting limit Ts of 20 ° C. or higher and an upper melting limit Tf of 30 ° C. or lower. Here, the melting lower limit temperature Ts means a lower limit temperature at which the latent heat storage material composition develops latent heat of fusion, and the melting upper limit temperature Tf means an upper limit temperature at which the latent heat storage material composition develops latent heat of fusion. .
図面を参照して融解下限温度Ｔｓ及び融解上限温度Ｔｆについて説明する。図１は、潜熱蓄熱材組成物の融解潜熱を発現する温度と蓄熱量との関係の一例を示すグラフである。図１中、Ａは建造物の冷暖房用の蓄熱システムに好適な潜熱蓄熱材組成物ＭＡの示す曲線、Ｂは建造物の冷暖房用の蓄熱システムに好適でない潜熱蓄熱材組成物ＭＢの示す曲線である。また、図１中、Ｄは曲線Ａの融解下限温度Ｔｓ、Ｅは曲線Ａの融解上限温度Ｔｆ、Ｃは融解上限温度Ｔｆと融解下限温度Ｔｓとの差分である潜熱発生温度幅、をそれぞれ示す。なお、図１に示す、融解下限温度Ｔｓ２０℃及び融解上限温度Ｔｆ２９．５℃は一例であり、本実施形態において融解下限温度Ｔｓ及び融解上限温度Ｔｆはこれらの数値に限定されない。
The melting lower limit temperature Ts and the melting upper limit temperature Tf will be described with reference to the drawings. FIG. 1 is a graph showing an example of the relationship between the temperature at which the latent heat storage material composition develops latent heat of fusion and the amount of heat storage. In Figure 1, A is the curve showing the preferred latent heat storage material composition M A heat storage system for heating and cooling of buildings, B denotes a latent heat storage material composition M B is not suitable for heat storage system for heating and cooling of buildings It is a curve. Also, in FIG. 1, D indicates the lower melting temperature Ts of the curve A, E indicates the upper melting temperature Tf of the curve A, and C indicates the latent heat generation temperature width which is the difference between the upper melting temperature Tf and the lower melting temperature Ts, respectively. . Note that the melting lower limit temperature Ts of 20 ° C. and the melting upper limit temperature Tf of 29.5 ° C. shown in FIG. 1 are examples, and in the present embodiment, the melting lower limit temperature Ts and the melting upper limit temperature Tf are not limited to these numerical values.
曲線Ａは、潜熱発生温度幅Ｃが、建造物の冷暖房用の蓄熱システムの潜熱蓄熱材組成物に好適な２０℃以上３０℃以下（２９．５℃以下）にある。すなわち、曲線Ａの潜熱蓄熱材組成物ＭＡは、融解下限温度Ｔｓが２０℃以上かつ融解上限温度Ｔｆが３０℃以下になっている。この融解下限温度Ｔｓが２０℃以上かつ融解上限温度Ｔｆが３０℃以下の潜熱蓄熱材組成物ＭＡによれば、建造物の冷暖房の一般的な使用温度範囲において潜熱蓄熱材組成物の効率的な蓄熱、放熱が可能である。このため、潜熱蓄熱材組成物ＭＡは、建造物の冷暖房用の蓄熱システムの潜熱蓄熱材組成物として好適である。
In the curve A, the latent heat generation temperature width C is in a range of 20 ° C. or more and 30 ° C. or less (29.5 ° C. or less) suitable for a latent heat storage material composition of a heat storage system for cooling and heating a building. In other words, the latent heat storage material composition M A of the curve A, the melting lower limit temperature Ts is 20 ° C. or higher and the melting maximum temperature Tf is set to 30 ° C. or less. According to the melting lower limit temperature Ts is 20 ° C. or higher and the melting maximum temperature Tf is the latent heat storage material composition of 30 ° C. or less M A, efficient latent heat storage material composition in the general temperature range of heating and cooling of buildings Heat storage and heat dissipation are possible. Therefore, M A is the latent heat storage material composition is suitable as a latent heat storage material composition of the heat storage system for heating and cooling of buildings.
一方、曲線Ｂは、潜熱発生温度幅Ｃが、建造物の冷暖房用の蓄熱システムの潜熱蓄熱材組成物に好適な２０℃以上３０℃以下（２９．５℃以下）を逸脱している。すなわち、曲線Ｂの潜熱蓄熱材組成物ＭＢは、融解下限温度Ｔｓが２０℃未満になっている。また、図１の横軸と曲線Ｂとの２個の交点のうち高温側の交点、すなわち、潜熱蓄熱材組成物ＭＢの温度融解上限温度Ｔｆは、図１には数値を明記していないが、３０℃を超えるようになっている。このような潜熱蓄熱材組成物ＭＢは、蓄熱材組成物が本来有する蓄熱量の全てを建造物の冷暖房に用いることができないため、建造物の冷暖房用の蓄熱システムの潜熱蓄熱材組成物として好ましくない。
On the other hand, in the curve B, the latent heat generation temperature width C deviates from 20 ° C. to 30 ° C. (29.5 ° C. or less) suitable for a latent heat storage material composition of a heat storage system for cooling and heating a building. In other words, the latent heat storage material composition M B of the curve B is the melting lower limit temperature Ts is set to less than 20 ° C.. Further, the high-temperature side of the intersection of the two intersections of the horizontal axis and the curve B in FIG. 1, i.e., the temperature melting maximum temperature Tf of the latent heat storage material composition M B does not specify numerical values in FIG. 1 , But more than 30 ° C. Such latent heat storage material composition M B, it is not possible to use all of the heat storage amount with the heat storage material composition originally heating and cooling of buildings, as latent heat storage material composition of the heat storage system for heating and cooling of buildings Not preferred.
これに対し、従来の潜熱蓄熱材組成物として、例えば、特許文献１に、硫酸ナトリウム及び／又はその共晶塩と、水と、相分離抑制剤と、からなり、水を所定量含有する蓄熱材組成物が開示されている。特許文献１に記載される蓄熱材組成物によれば、これに含まれる硫酸ナトリウム１０水和物が凝固、融解を繰り返しても蓄熱量の低下が抑制される。
On the other hand, as a conventional latent heat storage material composition, for example, Patent Literature 1 discloses a heat storage comprising sodium sulfate and / or a eutectic salt thereof, water, and a phase separation inhibitor, and containing a predetermined amount of water. A material composition is disclosed. According to the heat storage material composition described in Patent Document 1, even if sodium sulfate decahydrate contained therein is repeatedly coagulated and melted, a decrease in heat storage amount is suppressed.
また、従来の潜熱蓄熱材組成物として、非特許文献１には、硫酸ナトリウム１０水和物とリン酸水素二ナトリウム１２水和物との共晶型水和塩が開示されている。非特許文献１に記載される共晶型の蓄熱材組成物では、水等の融点調整剤を用いずに蓄熱材組成物の融点の低下を図っている。また、この共晶型の蓄熱材組成物によれば、凝固、融解を繰り返しても蓄熱量の低下が抑制される。
Non-Patent Document 1 discloses a eutectic hydrate of sodium sulfate decahydrate and disodium hydrogen phosphate decahydrate as a conventional latent heat storage material composition. In the eutectic heat storage material composition described in Non-Patent Document 1, the melting point of the heat storage material composition is reduced without using a melting point modifier such as water. Further, according to the eutectic type heat storage material composition, even if solidification and melting are repeated, a decrease in heat storage amount is suppressed.
しかしながら、特許文献１の蓄熱材組成物には、蓄熱量が小さいという問題があった。また、特許文献１の蓄熱材組成物に含まれ、蓄熱材作用に関与する硫酸ナトリウム１０水和物は、相変化温度が約３２℃であり、融解上限温度Ｔｆが３０℃を超える。さらに、非特許文献１に記載される共晶型の蓄熱材組成物は、相変化温度が約２９～３２℃であり、融解上限温度Ｔｆが実質的に３０℃を超える。
However, the heat storage material composition of Patent Document 1 has a problem that the heat storage amount is small. Further, sodium sulfate decahydrate, which is included in the heat storage material composition of Patent Document 1 and participates in the action of the heat storage material, has a phase change temperature of about 32 ° C. and a maximum melting temperature Tf of more than 30 ° C. Furthermore, the eutectic type heat storage material composition described in Non-Patent Document 1 has a phase change temperature of about 29 to 32 ° C., and a melting upper limit temperature Tf substantially exceeding 30 ° C.
上記特許文献１及び非特許文献１の蓄熱材組成物は、融解上限温度が実質的に３０℃を超える。このため、特許文献１及び非特許文献１の蓄熱材組成物は、建造物の冷暖房の一般的な使用温度範囲である２０℃以上かつ３０℃以下における蓄熱量が小さくなる。したがって、特許文献１及び非特許文献１の蓄熱材組成物は、建造物の冷暖房用の蓄熱システムの潜熱蓄熱材組成物として好適でないという問題があった。
熱 The heat storage material compositions of Patent Document 1 and Non-Patent Document 1 have a melting upper limit temperature substantially exceeding 30 ° C. For this reason, the heat storage material compositions of Patent Literature 1 and Non-Patent Literature 1 have a small amount of heat storage at 20 ° C. or more and 30 ° C. or less, which is a general use temperature range for cooling and heating a building. Therefore, the heat storage material compositions of Patent Document 1 and Non-Patent Document 1 have a problem that they are not suitable as a latent heat storage material composition of a heat storage system for cooling and heating a building.
さらに、特許文献１の蓄熱材組成物には、含んでいる水により潜熱蓄熱材組成物の相変化の生じる温度幅が大きくなるため、潜熱発生温度幅が大きいという問題もあった。
(4) Further, the heat storage material composition of Patent Document 1 has a problem that the temperature range in which the phase change of the latent heat storage material composition occurs due to the contained water is large, so that the latent heat generation temperature range is large.

（蓄熱材モジュール）
蓄熱材モジュールとしては、例えば、前記蓄熱材組成物を十分な密封性を有する容器に充填させた蓄熱材パックからなり、この蓄熱材パックを単数ないしは複数積層させるとともに、適切な流路を設け、モジュール化したものが用いられる。蓄熱材パックに用いる容器としては、例えば、アルミシートに樹脂製シートを積層して形成されたアルミパックシートを熱溶着することで形成されたアルミパック等が挙げられる。蓄熱材モジュールは、建造物中の空間を区切る床面、壁面、天井面の少なくとも一部に設置される。 (Heat storage material module)

Modularized ones are used.

The heat storage material module is installed on at least a part of a floor surface, a wall surface, and a ceiling surface that divide a space in a building.
このように設置された蓄熱材モジュールは、モジュール表面とこのモジュール表面を通気した雰囲気との熱交換、日射による日射熱、夜間電力を利用した空調システム等によって蓄熱（蓄冷）される。例えば、昼間においては、蓄熱材モジュール中の蓄熱材組成物は、建造物中の空間から得た熱によって融解し、その分のエンタルピーを蓄熱材組成物の内部に保留する。その後、夜間に外気温度が下がってくると、融解していた蓄熱材組成物は凝固し、建造物中の空間へ熱を放出する。このように、蓄熱材モジュールを建物内に設置すると、蓄熱材組成物の融解・凝固の作用により、冷暖房のためのエネルギー負荷を低減することができる。

For example, in the daytime, the heat storage material composition in the heat storage material module is melted by the heat obtained from the space in the building, and the enthalpy of that heat is retained inside the heat storage material composition. Thereafter, when the outside air temperature falls at night, the heat storage material composition that has melted solidifies and releases heat to the space in the building. Thus, when the heat storage material module is installed in a building, the energy load for cooling and heating can be reduced by the action of melting and solidifying the heat storage material composition.
