は、過冷却現象は大きな障害となっている。There is a latent heat storage tank that stores thermal energy using phase change latent heat from a liquid phase to a solid phase and uses this thermal energy for air conditioning and the like. However, when a latent heat storage agent such as water or water salt is used in a latent heat storage tank, if the cooling capacity of the refrigerator is small compared to the amount of sensible heat of the latent heat storage agent and the cooling rate is slow, overcooling may occur. arise. If the supercooled state is not escaped, latent heat storage becomes impossible, the amount of heat storage is extremely reduced, and it becomes impossible to obtain a constant heat source at the phase change temperature. Alternatively, even if the temperature reaches the natural coagulation temperature and coagulation starts, the heat storage loss is significant and the coagulation takes a long time. Therefore, the supercooling phenomenon is a major problem in air conditioning equipment that melts ice, hydrated salts, etc. of the same phase and uses it for cooling and heating.

固できなかった。Now, supercooling is a kind of metastable state, and conventionally, when microscopic objects such as crystals are introduced or shaken suddenly9, nuclei are generated and mutual love occurs, resulting in a transition to a stable state. known from experience. However, when using either method, the effect was insufficient and solidification could not be achieved reliably at the phase change temperature.

する甘でに時間がかかるという欠点があった。FIG. 1 shows a conventional example in which vibration is used. In an experiment in which a current was applied from an AC power supply 6 to the coil 5 of the electromagnet 4 to vibrate the diaphragm 7, and a sample container 2 filled with Ic water 1 was connected and cooled, the freezing temperature rose above the natural freezing temperature due to the vibration. It has been reported that However, in this example, although the sample container 2 is cooled while being vibrated, the disadvantage is that it takes a long time for the vibration to take effect, generate nuclei, and start freezing.
本発明は上記欠点を解決するためになされたもので、水

槽を提供するものである。The present invention has been made in order to solve the above-mentioned drawbacks, and provides a latent heat storage tank in which latent heat storage agents such as water and water salts can completely start solidifying almost instantly without supercooling or even if supercooled. It is something.

らすことができ、前記目的を達成している。In the present invention, by applying ultrasonic vibrations of 10 to 50 KH2 to one end of the heat storage capsule (7), it is possible to create the entire core of solidification in this part and harden the entire inside of the capsule, thereby achieving the above purpose. Achieved.
１、超音波振動の蔭になるカプセルができず、均一に凝

凝固させることができる。FIG. 2 shows an embodiment of the present invention. In a cylindrical heat storage container 15, a plurality of columnar heat storage capsules 13 are housed coaxially with the heat storage container 15 at appropriate intervals. A latent heat storage agent 17 is enclosed within the heat storage capsule 13. The temperature of the brine 14 as a heat medium is the same as that of the latent heat storage material 17.
The temperature is lower than the phase change temperature of latent heat storage tank 1.
It flows into the inlet provided at the bottom of 6 and exits from the outlet provided at the top. In general, the density of brine becomes higher when the temperature is lower. It will be cooled from the bottom end, and this part will cool down particularly well. On the other hand, a plurality of ultrasonic vibration elements 11 are attached to the lower end of the latent heat storage tank 16, and can be vibrated by the ultrasonic oscillator 12. Therefore, if ultrasonic waves are irradiated from the lower end of the latent heat storage tank 16 when the latent heat storage material 17 inside the heat storage capsule 13 has supercooled, solidification nuclei 18 will be generated at the bottom of each of the heat storage capsules 13, and from there Since the solid phase grows, the heat storage capsules 13 throughout the tank can be solidified almost instantly and uniformly.

This brine 14 is constantly cooled to a set temperature of 0° C. or lower by a refrigerator (not shown).

Brine 14 cooled to a constant temperature is supplied. Heat storage material in the brine 14 cooled to this temperature]7 as +
The heat storage capsule 13 sealed with water at a temperature of 25° C. was submerged and fixed, and cooled. The freezing point of tap water is approximately 0°C, and the freeze transition status of tap water was observed with meat, and changes in water temperature were measured with a thermocouple 24. The results are shown by the solid line in FIG. That is, as is clear from FIG. 3, the heat storage material 1 in the heat storage capsule 13 submerged in the brine 14
In case No. 7, 6 minutes after the start of cooling, the water temperature fell below the freezing point of 0°C, but it entered a supercooled state without freezing. After about 12 minutes of further cooling, the water temperature reached about -6°C, and although 1 hour had passed since the start of cooling, it did not reach level 1, where it gradually froze. The above test was repeated 10 times, but no freezing was observed in all trial sales.

Immediately before reaching C, power was supplied from the ultrasonic oscillator 12 to the ultrasonic transducer 11, and the entire heat storage capsule 13 was irradiated with ultrasonic waves. As a result, as shown in Fig. 4, the tap water instantly started freezing at around 0°C, and the supercooling phenomenon was prevented. This test was repeated 10 times, but the same results were obtained and reproducibility was obtained. In the figure, the dashed line is the brine temperature. The table below shows the results showing specific examples of the ultrasonic test conditions applied to the container. Here, the distance from the horn tip 19a to the container trench was 20 mm.

し、瞬時に凍結を開始した。Specific Example 3 Next, the capsule 13 containing the heat storage material 17 used in Specific Example 1 was supercooled, and then ultrasonic waves were supplied to the capsule 13. The temperature of the tap water in the capsule 13 rose to 0° C. almost at the same time as the ultrasonic wave was supplied, and the tap water froze. The results are shown in FIGS. 5 and 6. That is, Fig. 5 shows the case where ultrasonic waves are supplied when the heat storage material 17 is supercooled to =4°C in the housing, and Fig. 6 shows the case where ultrasonic waves are supplied after supercooling the heat storage material 17 to -6°C. It shows the characteristics. In either case, the temperature of the heat storage material 17 rose to 0° C. at the same time as the ultrasonic wave, and started freezing instantly.

成されるものと推測される。The present inventors have investigated the cause of freezing at the same time as ultrasonic wave supply in Specific Examples 1 to 3, but it is difficult to elucidate the principle because the operation is instantaneous. However, it is presumed that cavitation occurs in the heat storage material due to the ultrasonic waves supplied into the heat storage material 17, and this cavitation causes bubbles to be generated in the liquid of the heat storage material 18, and these bubbles are instantly collapsed. One. It is thought that crystal nuclei are generated when the shock waves generated when the bubbles collapse propagate through the heat storage material, and these nuclei grow and freeze. Therefore, it is presumed that the impact force generated when the bubble collapses is so large that it instantly collapses and forms a nucleus.

るものがある。The present inventors conducted a test using the frequency and power supplied to the heat storage material as parameters as shown in Tables 1 and 2. The above-mentioned instantaneous vegetation Jf! l: From the inference made by Naoki, the factors that cause cavitation are the type of liquid, its temperature, the frequency and power supplied to the liquid, and if the former factors are fixed, then in order to obtain the necessary impact force,
We considered that it depends on the supply frequency and power, and investigated the upper and lower limits of its value. What this table shows, when considered together with Figures 5 and 6, means that a technology has been achieved that allows instant freezing and allows full control of the freezing start temperature. The effect is extremely impressive.
