発生方法及び高温熱発生方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a heat storage device that stores thermal energy in a state of converting it into chemical energy and extracts the thermal energy as needed, and a method of using the device. In particular, the present invention relates to a heat storage device using a liquid heat storage agent, a heat storage method using the device, a cold heat generation method, and a high temperature heat generation method.
エネルギーの有効利用として太陽熱など自然のエネルギ
ーや各種工場排熱などの低コスト熱源があるが、それら
は供給が不安定であり、かつ限定されるため利用しにく
く、利用するためにはエネルギーの蓄熱が必要となって
くる。Low-cost heat sources such as natural energy such as solar heat and waste heat from various factories are effective ways to use energy, but their supply is unstable and limited, making them difficult to use. becomes necessary.
上記のような熱源を利用して冷房や暖房を行う装置では
、その熱を一時貯蔵し、必要に応じて取り出せる蓄熱機
能をもったものが望ましく、しかも取り出す熱エネルギ
ーは利用目的に応じて冷房の時はより低温が、暖房の時
はより高温が取り出せることが望ましい。For devices that perform air conditioning or heating using heat sources such as those mentioned above, it is desirable to have a heat storage function that temporarily stores the heat and extracts it as needed.Moreover, the extracted thermal energy can be used for cooling or heating depending on the purpose of use. It is desirable to be able to obtain a lower temperature when heating the room, and a higher temperature when heating the room.
熱エネルギー貯蔵方法には、そのまま熱運動形で貯える
方法として、（１）顕熱利用（温度差）と（２）潜熱利
用（固体から液体、又は液体から気体への相変化）があ
り、化学エネルギーに変換して貯える方法として、（３
）化学反応熱利用と（４）濃厚液の希釈熱による濃度差
利用、及びそれらの組合せによる方法がある。There are two ways to store thermal energy: (1) sensible heat utilization (temperature difference) and (2) latent heat utilization (phase change from solid to liquid or liquid to gas). As a method of converting and storing energy, (3
There are two methods: (4) utilizing the heat of a chemical reaction, (4) utilizing the concentration difference due to the heat of dilution of a concentrated liquid, and a combination thereof.
そのなかで、比熱の大きい水等を用いる顕熱利用の蓄熱
方式は、蓄熱密度（蓄熱液単位重量出たりの蓄熱量）が
小さいため蓄熱装置が大型化すると共に保温性の高い断
熱構造としなければならないという問題点がある。固体
の融解熱を利用した方式では、蓄熱密度は大きいが液体
から固体への相変化において、過冷却現象により、固化
しにくく、かつ過熱現象により液化しにくい等の操作上
の問題点があるとともに、固体であるため熱の伝わりが
悪く装置が大型化する欠点がある。Among these, heat storage methods that use sensible heat using water, etc., which have a high specific heat, have a small heat storage density (the amount of heat stored per unit weight of heat storage liquid), so the heat storage device becomes larger and must have an insulated structure with high heat retention. There is a problem that it must be done. Methods that use the heat of fusion of solids have a high heat storage density, but there are operational problems such as difficulty in solidifying due to supercooling phenomenon and difficulty in liquefying due to overheating during the phase change from liquid to solid. Since it is a solid, it has poor heat conduction and has the drawback of increasing the size of the device.
さらに熱運動形で貯える方式の共通の問題点としては、
熱の貯蔵時と出熱時の温度レベルは原理的には同じであ
るが、実際には放熱ロス、熱交換温度差等があるために
、出熱時の温度レベルが貯蔵時よりも低下する。さらに
熱利用時に目的に応じて取り出す温度を変えることがで
きず、蓄熱時は、放熱を防止するため保温性の高い断熱
構造にする必要がある。Furthermore, common problems with thermal kinetic storage methods include:
In principle, the temperature level during heat storage and heat release is the same, but in reality, due to heat radiation loss, heat exchange temperature difference, etc., the temperature level during heat release is lower than during storage. . Furthermore, when using heat, it is not possible to change the temperature taken out depending on the purpose, and when storing heat, it is necessary to use an insulating structure with high heat retention to prevent heat radiation.
これに対して、熱エネルギーを化学エネルギーへ変換し
た形で蓄熱する方式は、比較的低温状態での貯蔵ができ
るので、貯蔵時の放熱が大幅に防止でき、長期貯蔵が可
能になるなど、顕熱や潜熱を利用したシステムに比べ有
効利用がはかれる。On the other hand, methods that store heat by converting thermal energy into chemical energy can store heat at relatively low temperatures, which greatly prevents heat radiation during storage and enables long-term storage. It can be used more effectively than systems that use heat or latent heat.

って説明する。水は水蒸気が多孔性材料の孔を通ってく
る前に多孔性材料の表面で凝縮してしまう。As a conventional technique for storing heat by converting thermal energy into chemical energy, there is a heat storage device using a hydrophobic porous material as described in Japanese Patent Application Laid-Open No. 157995/1983. This heat storage device is shown in FIG. This is a device that converts thermal energy into chemical energy and stores it using the heat of formation and decomposition of a compound. It is equipped with a heat transfer tube 610 that exchanges heat or decomposition heat, and allows the refrigerant gas to pass therethrough.The absorbent solution (heat storage liquid) 20 is provided with a wall 1000 formed of a water-repellent porous material that has a water-repellent property that prevents the refrigerant gas from passing through. The air chamber 30 and the absorbent storage section 770 are separated from each other. Further, the storage container 250 that stores the refrigerant (liquid medium) 10 houses a heat transfer tube 210 that exchanges heat of condensation and heat of evaporation of the refrigerant 10 between the refrigerant and the absorbent solution 20. A heat exchange coil 230 is provided around the refrigerant to heat the refrigerant. This method has the advantage of integrating the heat exchanger and the absorbent storage container, but porous materials cannot be used on the refrigerant side for the following reasons, making it difficult to uniformly evaporate the refrigerant and reducing the size of the device. There are also limits. In addition, when the refrigerant is generated, the porous material cannot be used on the refrigerant side because it cannot prevent water droplets from being entrained and dispersed. The reason for this will be explained with reference to FIG. 3, taking as an example the case where water is retained in a hydrophobic porous material. Water condenses on the surface of the porous material before the water vapor passes through the pores of the porous material.
これは、水蒸気の水に対する凝縮（飽和）温度Ｔｓが蓄
熱液である水の凝縮温度と等しいために起こるものであ
る。つまり、水より水蒸気が発生し、多孔性材料の孔を
通る時は問題はないが、逆に水蒸気が孔を通って水の界
面で凝縮する時には操作温度ＴＬを凝縮温度Ｔｓ以下に
しなければならないが、そうすると水の疎水性の多孔性
材料の温度は等しくなるため、水蒸気が孔を通り抜ける
前に、多孔性材料の表面で凝縮（Ｔ Ｌ ＜ Ｔ ｓ
） シ、水まで達することはできない。This occurs because the condensation (saturation) temperature Ts of steam with respect to water is equal to the condensation temperature of water, which is a heat storage liquid. In other words, there is no problem when water vapor is generated more than water and passes through the pores of a porous material, but conversely, when water vapor passes through the pores and condenses at the water interface, the operating temperature TL must be lower than the condensation temperature Ts. However, since the temperature of water in the hydrophobic porous material is then equal, the water vapor condenses on the surface of the porous material before passing through the pores (T L < T s
) It cannot reach the water.
以上のことから多孔性材料の使用が限られ、その有効利
用がはかれなかった。For these reasons, the use of porous materials has been limited, and their effective use has not been achieved.
本発明の目的は、多孔性材料を用いることなしに蒸気の
