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 heating and cooling of a building, and more particularly to a heat storage material composition suitable for a heat storage system for heating and cooling of a building and a heat storage system for heating and cooling of a building containing 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 a phase change from a solid to a liquid is known. The latent heat storage material composition is used, for example, in a heat storage system for heating and cooling 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、融点が所定の温度領域内にあること、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。 Latent heat storage material compositions generally have a large amount of heat storage, a melting point within a predetermined temperature range, long-term stability, low cost, non-toxicity, and rotting property. Characteristics such as absence are required.
建造物の冷暖房用の蓄熱システム用の潜熱蓄熱材組成物には、単位重量当たりにどれだけ多くの熱を貯められるかを意味する全体融解潜熱ＨＴに加えて、狭い温度範囲で熱を吸放熱することが求められる。全体融解潜熱ＨＴが大きいと、少ない量で充分な蓄熱が達成できるため好ましい。狭い範囲で熱を吸放熱できると、無駄な吸放熱を起こすことなく、材料の持つ潜熱をシステムの目的とする温度範囲にて利用できるため好ましい。 The latent heat storage material composition for the heat storage system for heating and cooling of buildings absorbs heat in a narrow temperature range in addition to the total melt latent heat HT, which means how much heat can be stored per unit weight. It is required to dissipate heat. A large latent heat HT for melting is preferable because sufficient heat storage can be achieved with a small amount. It is preferable that heat can be absorbed and dissipated in a narrow range because the latent heat of the material can be used in the target temperature range of the system without causing unnecessary endothermic and heat dissipation.
「狭い温度範囲で熱を吸放熱できる特性」を表す指標として例えば５℃幅融解潜熱Ｈ５が用いられる。５℃幅融解潜熱Ｈ５とは「５℃の温度幅での融解潜熱の総量」を意味し、ある温度ＴからＴ＋５℃の温度範囲における融解潜熱の総量Ｑ５について、Ｔを変化させた際のＱ５の最大値として定義される。 For example, a 5 ° C. width melting latent heat H5 is used as an index representing "characteristics capable of absorbing and radiating heat in a narrow temperature range". 5 ° C width latent heat of melting H 5 means "total amount of latent heat of melting in a temperature range of 5 ° C", and when T is changed for the total amount of latent heat of melting Q 5 in the temperature range from a certain temperature T to T + 5 ° C. It is defined as the maximum value of Q5 of.
上記全体融解潜熱ＨＴは、示差走査熱量計（ＤＳＣ）にて測定されるヒートフローを時間で積分した場合のピーク面積から算出される。これに対し、５℃幅融解潜熱Ｈ５は、同様に示差走査熱量計（ＤＳＣ）にて測定されるヒートフローをある瞬間（時間ｔ１,温度Ｔ１）から温度Ｔ１＋５℃となった瞬間（時間ｔ１,温度Ｔ１＋５）まで時間積分し、その最大値として導出される。 The overall melting latent heat HT is calculated from the peak area when the heat flow measured by a differential scanning calorimeter (DSC) is integrated over time. On the other hand, in the 5 ° C. width melting latent heat H5, the temperature of the heat flow measured by the differential scanning calorimeter (DSC) became T 1 + 5 ° C. from a certain moment (time t 1 , temperature T 1 ). It is time-integrated up to the moment (time t 1 , temperature T 1 + 5) and derived as the maximum value.
図１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における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中の曲線は、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の示す曲線である。また、図２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における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２中の曲線は、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。 FIG. 1 is a graph showing an example of the relationship between the temperature at which the latent heat of melting is developed and the amount of heat storage in the latent heat storage material composition MA suitable for the heat storage system for heating and cooling of a building. The curve in FIG. 1 is a curve shown by the latent heat storage material composition MA suitable for a heat storage system for heating and cooling of a building. Further, FIG. 2 is a graph showing an example of the relationship between the temperature at which the latent heat of melting is developed and the amount of heat storage in the latent heat storage material composition MB , which is not suitable for the heat storage system for heating and cooling of buildings. The curve in FIG. 2 is a curve shown by the latent heat storage material composition MB, which is not suitable for a heat storage system for heating and cooling of a building.
図１及び図２に示す例では、加熱時に潜熱蓄熱材組成物が融解を開始する温度（融点Ｔm）は、１５℃を超え２０℃未満の範囲内にあり、適切である。なお、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、潜熱蓄熱材組成物の融解下限温度が低すぎると蓄熱材を凝固させて、冷熱を貯めることが困難となる。また、潜熱蓄熱材組成物の融解下限温度が高すぎると、外気との熱の交換効率が悪くなる。したがって、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、図１及び図２に示すように、融点Ｔmは１５～２０℃の範囲にあることが好ましい。 In the examples shown in FIGS. 1 and 2, the temperature (melting point T m ) at which the latent heat storage material composition starts melting during heating is in the range of more than 15 ° C and less than 20 ° C, which is appropriate. When the latent heat storage material composition is used in a heat storage system for heating and cooling of a building, if the lower limit temperature for melting of the latent heat storage material composition is too low, the heat storage material is solidified and it becomes difficult to store cold heat. Further, if the lower limit temperature for melting of the latent heat storage material composition is too high, the efficiency of heat exchange with the outside air deteriorates. Therefore, when the latent heat storage material composition is used in a heat storage system for heating and cooling of a building, the melting point T m is preferably in the range of 15 to 20 ° C. as shown in FIGS. 1 and 2.
具体的には、図１に示すように、潜熱蓄熱材組成物ＭＡでは、融点Ｔmと、加熱時に融解を終了する温度（融解上限温度Ｔｆ）との差が小さく、融解上限温度Ｔｆが２６℃未満にある。このような場合、外部の雰囲気温度が融解上限温度Ｔｆをわずかに上回る温度（例えば２６℃）となった場合でも、図１中に斜線領域Ａ１として表される蓄熱量、すなわち蓄熱材組成物が本来有する蓄熱量の全て、を冷熱として用いることができる。このように潜熱蓄熱材組成物ＭＡは、本来有する蓄熱量の全てを冷熱として発揮できるため、冷房用の蓄熱システム用の蓄熱材組成物として好適である。 Specifically, as shown in FIG. 1, in the latent heat storage material composition MA , the difference between the melting point T m and the temperature at which melting ends during heating (melting upper limit temperature T f ) is small, and the melting upper limit temperature T f is below 26 ° C. In such a case, even when the external atmospheric temperature is slightly higher than the melting upper limit temperature T f (for example, 26 ° C.), the heat storage amount represented as the shaded area A1 in FIG. 1 , that is, the heat storage material composition. All of the heat storage amount originally possessed by the object can be used as cold heat. As described above, the latent heat storage material composition MA is suitable as a heat storage material composition for a heat storage system for cooling because all of the inherent heat storage amount can be exhibited as cold heat.
一方、図２に示すように潜熱蓄熱材組成物ＭＢでは、融点Ｔmと融解上限温度Ｔｆとの差異が大きく、融解上限温度Ｔｆが２６℃を超える。この場合、上述と同様に外部の雰囲気温度が２６℃となったとき、２６℃から融解上限温度Ｔｆまでの温度範囲での蓄熱量は、冷房に寄与しないこととなる。すなわち、潜熱蓄熱材組成物ＭBでは、外部温度が２６℃を超える場合、図２に斜線領域Ａ２として示される蓄熱量、すなわち蓄熱材組成物が本来有する蓄熱量の一部のみ、しか冷熱として用いることができない。このように潜熱蓄熱材組成物ＭＢは、冷房用の蓄熱システム用の蓄熱材組成物として好ましくない。 On the other hand, as shown in FIG. 2, in the latent heat storage material composition MB, the difference between the melting point T m and the upper limit melting temperature T f is large, and the upper limit melting temperature T f exceeds 26 ° C. In this case, when the external atmospheric temperature becomes 26 ° C. as described above, the amount of heat stored in the temperature range from 26 ° C. to the upper limit melting temperature T f does not contribute to cooling. That is, in the latent heat storage material composition MB, when the external temperature exceeds 26 ° C., only a part of the heat storage amount shown as the shaded area A 2 in FIG. 2, that is, the heat storage amount originally possessed by the heat storage material composition is cooled. Cannot be used as. As described above, the latent heat storage material composition MB is not preferable as a heat storage material composition for a heat storage system for cooling.
このように冷房用の蓄熱システム用の蓄熱材組成物は、１５～２０℃の範囲にて融解し、かつ狭い温度範囲で多量の熱を吸熱する特性が求められる。ここで、「狭い温度範囲で多量の熱を吸熱する特性」を表す指標としての５℃幅融解潜熱Ｈ５について、図３及び図４を用いて説明する。図３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の５℃幅融解潜熱Ｈ５を説明する図である。図３中の曲線は、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の示す曲線である。図４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の５℃幅融解潜熱Ｈ５を説明する図である。図４中の曲線は、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。 As described above, the heat storage material composition for a heat storage system for cooling is required to have a property of melting in a range of 15 to 20 ° C. and absorbing a large amount of heat in a narrow temperature range. Here, the 5 ° C. width melting latent heat H5 as an index showing "characteristics of absorbing a large amount of heat in a narrow temperature range" will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram illustrating a 5 ° C. width melting latent heat H5 of a latent heat storage material composition suitable for a heat storage system for heating and cooling of a building. The curve in FIG. 3 is a curve shown by the latent heat storage material composition MA suitable for a heat storage system for heating and cooling of a building. FIG. 4 is a diagram illustrating a 5 ° C. width melting latent heat H5 of a latent heat storage material composition that is not suitable for a heat storage system for heating and cooling of a building. The curve in FIG. 4 is a curve shown by the latent heat storage material composition MB, which is not suitable for a heat storage system for heating and cooling of a building.
５℃幅融解潜熱Ｈ５とは前述の通り、「５℃の温度幅での融解潜熱の総量」を意味し、ある温度ＴからＴ＋５℃の温度範囲における融解潜熱の総量Ｑ５についてＴを変化させた際のＱ５の最大値として定義される。ここで、その際の温度の下限値を５℃幅下限温度Ｔ５Ｌ、上限値を５℃幅下限温度Ｔ５Ｈと定義する。 As described above, the 5 ° C. width latent heat of melting H 5 means "the total amount of latent heat of melting in the temperature range of 5 ° C.", and T is changed with respect to the total amount of latent heat of melting Q 5 in the temperature range from a certain temperature T to T + 5 ° C. It is defined as the maximum value of Q5 when it is made to do so. Here, the lower limit of the temperature at that time is defined as 5 ° C. width lower limit temperature T 5L , and the upper limit value is defined as 5 ° C. width lower limit temperature T 5H .
潜熱蓄熱材組成物ＭＡでは図３中の斜線領域Ａ１の総和が５℃幅融解潜熱Ｈ５となる。潜熱蓄熱材組成物ＭＡでは狭い温度範囲において鋭い蓄熱量のピークが存在することから、結果として５℃幅融解潜熱Ｈ５は大きな値を示す。同様に潜熱蓄熱材組成物ＭＢにおいても図４中の斜線領域Ａ２の総和が５℃幅融解潜熱Ｈ５となる。しかし、潜熱蓄熱材組成物ＭＢではピークの形状が緩やかであるため、５℃幅融解潜熱Ｈ５は小さな値を示す。 In the latent heat storage material composition MA, the total sum of the shaded areas A1 in FIG. 3 is the latent heat H5 for melting at a width of 5 ° C. Since the latent heat storage material composition MA has a sharp peak of heat storage amount in a narrow temperature range, the latent heat H 5 for melting at 5 ° C. shows a large value as a result. Similarly, in the latent heat storage material composition MB, the sum of the shaded areas A 2 in FIG. 4 is the latent heat H 5 for melting at a width of 5 ° C. However, since the shape of the peak is gentle in the latent heat storage material composition MB, the latent heat H 5 for melting at 5 ° C. shows a small value.
このように狭い温度範囲で多量の熱を吸熱する蓄熱材ほど、５℃幅融解潜熱Ｈ５は大きな値を示すことから、５℃幅融解潜熱Ｈ５を「狭い温度範囲で多量の熱を吸熱する」特性の指標として用いることができる。 Since a heat storage material that absorbs a large amount of heat in such a narrow temperature range shows a large value in the latent heat H 5 for melting in a width of 5 ° C., the latent heat H 5 for melting in a width of 5 ° C. It can be used as an index of the characteristic of "doing".
しかしながら、硫酸ナトリウム１０水和物は、相変化温度が約３２℃であるため、特許文献１の蓄熱材組成物では、融点を２０～２２．５℃の範囲内に調整することが困難であるという問題があった。また、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。さらに、特許文献１の蓄熱材組成物では、水を加えると、潜熱発生領域が増大するため、狭い温度領域内での融解潜熱が小さいという問題があった。
However, since the phase change temperature of sodium sulfate decahydrate is about 32 ° C., it is difficult to adjust the melting point within the range of 20 to 22.5 ° C. in the heat storage material composition of
本発明は、上記課題に鑑みてなされたものである。本発明は、融点が２０～２２．５℃の範囲内にあり、狭い温度領域内での融解潜熱が大きい蓄熱材組成物及び建築物の冷暖房用の蓄熱システムを提供することを目的とする。 The present invention has been made in view of the above problems.

［建築物の冷暖房用の蓄熱システム］
本実施形態に係る建築物の冷暖房用の蓄熱システムは、上記本実施形態に係る蓄熱材組成物を用いた蓄熱材モジュールを具備する。
[Heat storage system for heating and cooling of buildings]
The heat storage system for heating and cooling of a building according to the present embodiment includes a heat storage material module using the heat storage material composition according to the present embodiment.
（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)
The heat storage material module is, for example, composed of a heat storage material pack in which the heat storage material composition is filled in a container having sufficient sealing property, and one or more of the heat storage material packs are laminated and an appropriate flow path is provided. Modularized ones are used. Examples of the container used for the heat storage material pack include an aluminum pack formed by heat-welding an aluminum pack sheet formed by laminating a resin sheet on an aluminum sheet. The heat storage module is installed on at least a part of the floor, wall surface, and ceiling surface that divides the space in the 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。 The heat storage material module installed in this way is stored (cooled) by heat exchange between the module surface and the atmosphere ventilated on the module surface, solar heat by solar radiation, an air conditioning system using nighttime power, and the like. 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 corresponding to the heat is retained inside the heat storage material composition. After that, when the outside air temperature drops at night, the melted heat storage material composition solidifies and releases heat to the space inside the building. In this way, when the heat storage material module is installed in the building, the energy load for heating and cooling can be reduced by the action of melting and solidifying the heat storage material composition.
