【発明の詳細な説明】 （産業上の利用分野） この発明は、融解潜熱を利用する蓄冷剤の改良に関す

の分野で用いられている。(Prior Art) A regenerator cools surrounding objects over a long period of time by utilizing latent heat of melting when melting from a frozen state, and is used in various fields.

ものである。Conventionally, regenerators are roughly classified into two types. One is composed of an aqueous solution prepared by dissolving one or several kinds of inorganic salts such as sodium chloride, potassium nitrate, and sodium nitrate in water at a predetermined freezing temperature, and the other is methanol. And an aqueous solution prepared by dissolving an alcohol such as ethanol, ethylene glycol or the like in water so as to have a predetermined freezing temperature.

間維持できない問題がある。(Problems to be Solved by the Invention) However, the former regenerator composed of an aqueous solution of an inorganic salt is highly corrosive to a metal, and corrodes the metal when it comes into contact with a metal such as copper or aluminum. There is a problem that the container cannot be used. In the latter, the cold storage agent composed of an aqueous alcohol solution has much lower metal corrosivity than the cold storage agent composed of an inorganic salt aqueous solution, and can be used for metal pipes. There is a problem that the latent heat of fusion is smaller than that of the regenerator and the low temperature cannot be maintained for a long time.

熱による外部熱の吸収を良好にする。(Operation) The aqueous solution of the inorganic salt contained in the water-impermeable pouch has a large latent heat of fusion, and the latent heat of fusion maintains the temperature of the entire regenerator at a low temperature for a long time. The water-impermeable pouch storing the aqueous solution of the inorganic salt prevents the aqueous solution of the inorganic salt having a high metal corrosivity from directly touching the wall of the metal tube or the metal container, and suppresses the corrosion of the metal tube or the container. On the other hand, the alcohol aqueous solution fills the gap between the wall of the metal tube or the container and the pouch without gaps, and improves the heat transfer between the inorganic salt aqueous solution in the pouch and the wall of the metal tube or the container,
When the cold storage agent 10 is used, the freezing time of the inorganic salt aqueous solution in the small bag 14 is shortened, and the absorption of external heat by the latent heat of melting of the frozen inorganic salt aqueous solution is improved.
（実施例） 以下この発明を、より具体的に説明する。(Example) Hereinafter, the present invention will be described more specifically.

る。The water-impermeable pouch 14 is for preventing an aqueous solution of an inorganic salt having high metal corrosivity from coming into contact with the wall of the metal refrigerant tube 12, and is preferably formed of a plastic film such as polyethylene. The size of the small bag 14 is determined in consideration of the interval between the metal refrigerant pipe 12 and the wall of the container 13, the freezing speed of the inorganic salt aqueous solution in the small bag 14, and the like. The reason is that if the pouch 14 is too large, it will not enter between the metal refrigerant pipe 12 and the container 13, and when using the regenerator 10, when the inorganic salt aqueous solution in the pouch 14 is frozen by external cooling, Since the cooling and freezing of the inorganic salt aqueous solution are performed by the transfer of heat by the alcohol aqueous solution 16 around the pouch 14, if the pouch 14 is large, the inorganic salt aqueous solution at the approximate center in the pouch 14 and the alcohol aqueous solution outside the pouch 14 This is because the distance from the container 16 becomes large, and the freezing time of the aqueous inorganic salt solution in the center of the pouch 14 becomes longer. For this reason, the size of the small pouch 14 is usually adjusted so that the amount of the inorganic salt aqueous solution to be enclosed is 0.1 to 100 g, preferably 0.1 to 2 g, and the amount of the inorganic salt aqueous solution accommodated between the metal refrigerant pipe 12 and the container 13. To adjust the number of pouches 14.

Is prepared by dissolving a predetermined amount of the above in water. As the inorganic salt, sodium chloride, ammonium chloride, magnesium chloride, calcium chloride, potassium nitrate, sodium nitrate and the like are used.

きくするため99:1〜50:50の範囲とされる。Also, the alcohol aqueous solution 16 fills the small bag 14 between the metal refrigerant tube 12 and the container 13 to improve the heat transfer efficiency between the inorganic salt aqueous solution in the small bag 14 and the metal refrigerant tube 12 and the container 13, The cold storage effect is intended to be improved by utilizing the latent heat of fusion of the alcohol aqueous solution 16 itself.
Examples of the alcohol include methanol, ethanol, ethylene glycol, propylene glycol, and glycerol.
It is selected so as to be equal to or lower than the freezing temperature of the aqueous solution of the inorganic salt therein, and the mixing amount with water is also determined. The reason that the freezing temperature of the aqueous alcohol solution 16 is set to be lower than the freezing temperature of the aqueous solution of the inorganic salt in the small bag 14 is that the small bag is cooled by external cooling when using the regenerator.
When freezing the aqueous solution of the inorganic salt in 14, when the freezing temperature of the aqueous solution of the alcohol is higher than the freezing temperature of the aqueous solution of the inorganic salt in the pouch, the aqueous solution of the alcohol freezes faster than the aqueous solution of the inorganic salt in the pouch, and then freezes in the aqueous solution of the alcohol. In this case, heat convection does not occur and the heat transfer efficiency is extremely reduced, so that it takes a long time to freeze the inorganic salt aqueous solution in the pouch. Usually, the freezing temperature of the aqueous alcohol solution is preferably 0 to 5 ° C. lower than the freezing temperature of the aqueous inorganic salt solution in the pouch. Further, the ratio of the total weight of the aqueous inorganic salt solution to the total weight of the aqueous alcohol solution in the regenerator 10 is determined within a range in which the aqueous alcohol solution 16 can fill the periphery of the small bag 14 without gaps. Alcohol aqueous solution = 99: 1 to 10:90, preferably 99: 1 to 50:50 in order to increase the latent heat of fusion of the entire regenerator.

It is measured over time.
