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、所定の温度範囲で融解・凝固すること、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。 Latent heat storage material compositions generally have a large amount of heat storage, melt and solidify in a predetermined temperature range, are stable for a long period of time, are inexpensive, are non-toxic, and are perishable. 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 of the heat storage system for heating and cooling of buildings, in addition to the entire latent heat of fusion H T to mean either be accumulated how much more heat per unit weight, absorption heat in a narrow temperature range It is required to dissipate heat. When the entire latent heat of fusion H T is large, preferable because sufficient heat storage can be achieved with less 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 heat absorption 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 H 5 is used as an index representing "characteristics capable of absorbing and radiating heat in a narrow temperature range". 5 ° C width melting latent heat H 5 means "total amount of melting latent heat in a temperature range of 5 ° C", and when T is changed for the total amount Q 5 of melting latent heat in the temperature range from a certain temperature T to T + 5 ° C. It is defined as the maximum value of Q 5.
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 total latent heat of fusion H T is calculated from the peak area in the case of integrated by heat flow times measured by a differential scanning calorimeter (DSC). On the other hand, the latent heat of melting at 5 ° C. H 5 became the temperature T 1 + 5 ° C. from a certain moment (time t 1 , temperature T 1 ) in the heat flow measured by the differential scanning calorimeter (DSC). Time integration is performed up to the moment (time t 1 , temperature T 1 + 5), and the maximum value is derived.
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。 Figure 1 is a graph showing an example of the relationship between the temperature and the heat storage amount expressing latent heat of fusion of suitable latent heat storage material composition M A heat storage system for heating and cooling of buildings. Curve in FIG. 1 is a curve showing the preferred latent heat storage material composition M A heat storage system for heating and cooling of buildings. 2 is a graph showing an example of the relationship between the temperature and the heat storage amount expressing latent heat of fusion of not suitable for heat storage system for heating and cooling of buildings latent heat storage material composition M B. Curve in FIG. 2 is a curve showing the not suitable in the heat storage system for heating and cooling of buildings latent heat storage material composition M B.
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（融解下限温度Ｔｓ）は、１３℃以上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、蓄熱材が融解を開始する温度は１３℃以上２０℃の範囲にあることが好ましい。 In the example shown in FIGS. 1 and 2, the temperature at which the latent heat storage material composition upon heating begins to melt (melting lower limit temperature T s) is in the range of less than 13 ° C. or higher 20 ° C., are suitable. 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 of 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 of 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 the heat storage system for heating and cooling of a building, the temperature at which the heat storage material starts melting may be in the range of 13 ° C. or higher and 20 ° C. as shown in FIGS. 1 and 2. preferable.
具体的には、図１に示すように、潜熱蓄熱材組成物ＭＡでは、融解下限温度Ｔｓ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, the latent heat storage material composition M A, the difference between the melting lower limit temperature T s, the temperature at which to end the melt during heating (melting upper limit temperature T f) small, melt limit The temperature T f is less than 26 ° C. In this case, even when the external atmospheric temperature becomes melting the upper limit temperature T f slightly greater than the temperature (e.g. 26 ° C.), heat storage quantity, expressed as the hatched area A 1 in FIG. 1, i.e. the heat storage material composition All of the heat storage amount originally possessed by the object can be used as cold heat. Thus the latent heat storage material composition M A is, because it can exert all the heat storage amount inherent the cold, is suitable as a heat storage material composition of the heat storage system for cooling.
一方、図２に示すように潜熱蓄熱材組成物ＭＢでは、融解下限温度Ｔｓ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, the latent heat storage material composition M B as shown in FIG. 2, a large difference between the melting lower limit temperature T s and the melting maximum temperature T f, the melting maximum temperature T f is higher than 26 ° C.. In this case, when the external ambient temperature reaches 26 ° C. as described above, the amount of heat stored in the temperature range from 26 ° C. to the upper melting limit temperature T f does not contribute to cooling. That is, in the latent heat storage material composition M B, if the external temperature exceeds 26 ° C., the heat storage amount shown in Fig. 2 as a hatched area A 2, i.e. only a portion of the heat storage amount with the heat storage material composition is originally only cold Cannot be used as. Thus the latent heat storage material composition M B is not preferred as a heat storage material composition of the 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、１３℃以上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 13 ° C. or higher and 20 ° C. and absorbing a large amount of heat in a narrow temperature range. Here, 5 ° C. width latent heat of fusion H 5 as an index representing the "property of the heat absorbing large amounts of heat in a narrow temperature range" will be described with reference to FIGS. FIG. 3 is a diagram illustrating a 5 ° C. width melting latent heat H 5 of a latent heat storage material composition suitable for a heat storage system for heating and cooling of a building. Curve in FIG. 3 is a curve showing the preferred latent heat storage material composition M A heat storage system for heating and cooling of buildings. Figure 4 is a diagram for explaining a 5 ° C. width latent heat of fusion H 5 of the latent heat storage material composition is not suitable for heat storage system for heating and cooling of buildings. Curve in FIG. 4 is a curve showing the not suitable in the heat storage system for heating and cooling of buildings latent heat storage material composition M B.
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℃幅上限温度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 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 Q 5 when allowed to. 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 upper 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。
The sum of the hatched areas A 1 in the latent heat storage
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。 More heat storage material absorbs a large amount of heat at such a narrow temperature range, from 5 ° C. width latent heat of fusion H 5 to a larger value, 5 ° C. width latent heat of fusion H 5 absorbs the large amount of heat in the "narrow temperature range It can be used as an index of the characteristic of "doing".
また、前述のように、蓄熱材が融解を開始する温度は１３℃以上２０℃の範囲にあることが好ましいが、図５に示すように融解下限温度Ｔｓと５℃幅下限温度Ｔ５Ｌとが大きく異なる場合がある。蓄熱材が図５に示す特性を有するの場合、蓄熱材が融解を開始する温度は融解下限温度Ｔｓとなるが、蓄熱材の大部分が融解する下限温度は５℃幅下限温度Ｔ５Ｌである。したがって、蓄熱材が図５に示す特性を有する場合は、蓄熱材の融解を開始する温度として融解下限温度Ｔｓよりも５℃幅下限温度Ｔ５Ｌを用いることが適切である。 Further, as described above, the temperature at which the heat storage material starts melting is preferably in the range of 13 ° C. or higher and 20 ° C., but as shown in FIG. 5, the lower limit melting temperature T s and the lower limit temperature 5 ° C. T 5 L are used. May differ significantly. When the heat storage material has the characteristics shown in FIG. 5, the temperature at which the heat storage material starts melting is the lower limit melting temperature T s , but the lower limit temperature at which most of the heat storage material melts is the lower limit temperature T 5 L in the width of 5 ° C. is there. Therefore, when the heat storage material has the characteristics shown in FIG. 5, it is appropriate to use a lower limit temperature T 5 L having a width of 5 ° C. higher than the lower limit melting temperature T s as the temperature at which the heat storage material starts melting.
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、塩化カルシウム６水和物に、塩化アンモニウム、臭化アンモニウム、及び硝酸アンモニウムの１種以上を加えた蓄熱材組成物が開示されている。 On the other hand, as a conventional latent heat storage material composition, for example, Patent Document 1 discloses a heat storage material composition in which one or more of ammonium chloride, ammonium bromide, and ammonium nitrate are added to calcium chloride hexahydrate. Has been done.
また、特許文献２に、塩化カルシウム６水和物を主成分とし、臭化カリウム、臭化ナトリウム、及び臭化アンモニウムの１種以上を加えた蓄熱材組成物が開示されている。 Further, Patent Document 2 discloses a heat storage material composition containing calcium chloride hexahydrate as a main component and adding one or more of potassium bromide, sodium bromide, and ammonium bromide.
しかしながら、特許文献１及び２の蓄熱材組成物で主成分として用いられる塩化カルシウム６水和物は、融点が２９．４℃程度と高く、塩化カルシウム６水和物以外の添加物の添加量が少ないと、融点が十分に低くならないという問題があった。また、特許文献１及び２の蓄熱材組成物において、塩化カルシウム６水和物以外の添加物の配合量が多いと、融点が低くなるものの、全体融解潜熱及び５℃幅融解潜熱が小さくなるという問題があった。このように、特許文献１及び２の蓄熱材組成物において、融点が十分に低く、かつ５℃幅融解潜熱が大きい配合は見出されていなかった。 However, the calcium chloride hexahydrate used as the main component in the heat storage material compositions of Patent Documents 1 and 2 has a high melting point of about 29.4 ° C., and the amount of additives other than calcium chloride hexahydrate added is high. If it is too small, there is a problem that the melting point is not sufficiently low. Further, in the heat storage material compositions of Patent Documents 1 and 2, if the amount of additives other than calcium chloride hexahydrate is large, the melting point is lowered, but the overall latent heat of melting and the latent heat of melting at 5 ° C. are reduced. There was a problem. As described above, in the heat storage material compositions of Patent Documents 1 and 2, no compound having a sufficiently low melting point and a large latent heat of melting in a width of 5 ° C. has been found.
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、５℃幅下限温度Ｔ５Ｌが１３℃以上２０℃未満の範囲内にあり、５℃幅融解潜熱Ｈ５が１３０Ｊ／ｇ以上である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 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 composed of, for example, 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. Modular 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 (cold) 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. When the heat storage material module is installed in the building in this way, the energy load for heating and cooling can be reduced by the action of melting and solidifying the heat storage material composition.
