凝固即ち放熱が開始されるのである。 When the salts inside 1 reach a supercooled state, the control mechanism 4 that detects this is activated and applies a voltage between the electrodes, thereby destroying the supercooling and starting solidification of the salts, that is, heat radiation. It is.

放熱を無限にくり返すことが可能である。 5 is a temperature detector, and 6 is a power switch. 4 closes 6 when the temperature inside the container reaches the supercooling temperature (for example, about 53 degrees Celsius when using sodium acetate trihydrate), and then the supercooling is destroyed and heat generation begins and the temperature rises slightly (for example, 6 when the temperature is 1~5℃)
If you set it to open, it will automatically store heat.
It is possible to repeat heat dissipation infinitely.
温度検出器は必ずしも塩類を収納した容器内に
付設する必要はなく、要は塩類の過冷却が検知出
来る場所であればいずれの場所でも良い。例えば
熱媒体中、熱交換器等任意の場所が選ばれる。 The temperature detector does not necessarily need to be attached to the container containing the salts, but may be placed anywhere as long as supercooling of the salts can be detected. For example, an arbitrary location such as in a heat medium or a heat exchanger is selected.
又、温度検出器のみに限らずタイムスイツチ等
を付設して指定時間に指定期間電圧を印加出来る
様に４を制御する等、適宜変更が可能である。 Further, it is possible to make appropriate changes, such as adding not only a temperature detector but also a time switch or the like to control 4 so that a voltage can be applied at a specified time for a specified period.

えのコツクである。 FIG. 3 shows one example of the simplest model heat storage device (of course, the present invention is not limited to such an example), and 1 is filled with an inorganic salt or an organic salt. 2 is an electrode, 3 is a power source, 4 is an automatic voltage application control mechanism, 5 is a temperature detector, 6 is a power switch, 7 is a heat exchanger made of a coiled copper pipe, p is a pump, and 8 is a water tank. It is filled with water and circulated through the heat exchanger, water tank, and radiator 9 by a pump. Further, 10 is a switch for switching the circulating water.

は停止する。 First, during the day, the water heated by the sun's heat in 8 is sent into 1 through a pipe. The heat exchanger 7 melts the heat storage material in 1 and stores heat. The heat-exchanged water is circulated to 8, and after being heated, it is introduced into 1 again. At night, switch the Kotoku 10 so that the circulating water flows to the radiator. The heat storage material in 1 begins to radiate heat, and the heat exchanger 7 warms the circulating water, which enters the radiator and is used for heating. The temperature detector 5 discovers the point at which heat dissipation progresses and cooling is recognized and no solidification heat is generated, and this is transmitted to the control mechanism 4 and
When the switch is closed, a voltage is applied between the electrodes 2. Then, after a few seconds, supercooling is broken and solidification begins, and the circulating water continues to be heated by the generation of solidification heat. When heat generation starts and the temperature inside 1 reaches or exceeds the set temperature, switch 6 is opened and voltage application is stopped.
