As shown in Japanese Patent No. 8538, a baffle plate-type supercooling release device has also been proposed, but it lacks reliability in releasing supercooling.
Furthermore, it was necessary to configure the device so as to eliminate the omnipresence of the generated ice in the heat storage tank 1, which caused problems such as the system becoming complicated.
この発明は上記のような課題を解消するためになされた
もので、過冷却の解除を確実に′行うことができるとと

とを目的とする。This invention was made to solve the above-mentioned problems, and it is possible to reliably release supercooling, and also to prevent freezing of the supercooling release device and dispersion of generated ice in the heat storage tank. The purpose of the present invention is to obtain an ice heat storage device that can prevent ice from occurring.
この発明に係る氷蓄熱装置は、過冷却した水または水溶
液を収容する蓄熱槽と、空気中の水分を微小な氷晶にし
て上記水または水溶液に到達させるコールドフィンガと
から構成したものである。The ice heat storage device according to the present invention includes a heat storage tank that contains supercooled water or an aqueous solution, and a cold finger that converts moisture in the air into minute ice crystals that reach the water or aqueous solution.
この発明におけるコールドフィンガは、空気中の水分を
氷晶化して、過冷却された水または水溶液に到達せしめ

水溶液中にシャーベット状の氷を成長せしめるように機
能する。The cold finger in this invention crystallizes moisture in the air and makes it reach supercooled water or aqueous solution, and the ice crystals that reach the water or aqueous solution form a sherbet-like substance in the water or aqueous solution. It functions to cause ice to grow.
以下、この発明の一実施例を図について説明する。第１
図において、１は蓄熱槽、４は過冷却器（図示せず）に
おいて過冷却され死水または水溶液を送出する出口、１
４は蓄熱槽１の水面上方に水Ｗと非接触状態で設置され

微細な氷晶である。An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 is a heat storage tank, 4 is an outlet through which dead water or aqueous solution is supercooled in a supercooler (not shown), and 1
4 is a cold finger such as a thermoelectric element installed above the water surface of the heat storage tank 1 without contact with the water W; 15 is a very fine ice crystal cooled by the cold finger 14 and released into the air.
次に動作について説明する。Next, the operation will be explained.

下降流に乗って蓄熱槽１の水面上に広がって到達する。The dead water or aqueous solution brought into a supercooled state by a supercooler (not shown) enters the heat storage tank 1 through the outlet 4 of the supercooled water. On the other hand, due to a phenomenon called the Peltier effect, the piezoelectric element described above generates heat on one side and cools the other side when energized, so if one side on the cooling side is used, it can be used as the cold finger 14. . This cold finger 14 is installed above the water surface of the heat storage tank 1 without contact with the supercooled water with the cooling surface facing downward, and by applying electricity, the air around the lower surface of the cold finger 14 is removed. Cooling. This cooled air causes a gentle downward flow due to the difference in specific gravity with the warm surrounding air, and the moisture in the air turns into minute ice crystals 15 and rides this downward flow to the heat storage tank 1. Spread out on the surface of the water and reach it.
このため、過冷却状態の水Ｗはこれらの広がった各氷晶
が核となって氷に成長する。すなわち、過冷却状態の解
除であり、過冷却水はその過冷却度に応じた割合の、氷
と水の固液混相状態のシャーベット状氷となる。Therefore, the supercooled water W grows into ice with each of these spread ice crystals serving as a nucleus. That is, the supercooled state is canceled, and the supercooled water becomes sherbet-like ice in a solid-liquid mixed phase state of ice and water in a proportion corresponding to the degree of supercooling.
従って、この熱電素子のコールドフィンガ１４への通電
は過冷却を最初に解除するときのみでも良く、この場合
、後は分散生成した水面上の氷が核となって過冷却を解
除することとなる。Therefore, it is sufficient to energize the cold finger 14 of this thermoelectric element only when first canceling supercooling, and in this case, the ice on the water surface that is dispersed and generated will serve as the core to cancel supercooling. .
なお、上記実施例ではコールドフィンガ１４による冷気

にファン１６ｔ−設けて、強制的に下降流を発生させる
ようにしてもよく、上記実施例の効果をより確実にでき
る。In the above embodiment, the cold air descends due to the cold finger 14 due to natural convection, but as shown in FIG. 2, a fan 16t may be provided to forcibly generate a downward flow. The effects of the embodiment can be more reliably achieved.
また、上記実施例ではコールドフィンガ１４として熱電
素子を用いた場合を示したが、冷凍機の冷却器の一部を
使用してもよい。Further, in the above embodiment, a thermoelectric element is used as the cold finger 14, but a part of a cooler of a refrigerator may also be used.

ことができる。As described above, according to the present invention, the cold finger is used as the supercooling release means and is arranged on the water surface in a non-contact state with the supercooled liquid, so that the ice particles in the heat storage tank are distributed. This not only improves the thermal responsiveness of the heat storage tank, but also produces solid-liquid mixed-phase sherbet-like ice with excellent fluidity and uniform size with good reproducibility.
また、空中に液と非接触状態でコールドフィンガが設け
