側熱交換器である。Gaseous hydrates are hydrocarbons such as methane, ethane, and propane, and Freon-based compounds such as R-11R-12 in the voids formed inside the skeleton of a three-dimensional structure formed by the bonding of water atoms or molecules. A specific crystal structure is constituted by incorporating a gas-based wettable powder. This gas hydrate has been attempted to be used for cold storage because of its large cold storage capacity.

When the gas hydrate 5 is produced by cooling with 7, the contact area between the wettable powder 2 and the water 3 is small and the production rate of the gas hydrate 5 is slow when the two layers are separated. Since the specific gravity of the hydrate 5 is intermediate between the specific gravities of the wettable powder 2 and the water 3, the gas hydrate 5 exists at the interface position between the wettable powder 2 and the water 3, and a new gas hydrate 5 Interfere with production.

とができる。Since the present invention is constructed as described above, it has the following effects. At the start of cold storage, the wettable powder is in the lower part and water is in the upper part in the cold storage tank. In the structure of claim (1), during the cold storage, the water in the upper part of the cold storage tank is sucked, cooled by the heat exchanger provided outside the cold storage tank, and blown into the bottom part of the cold storage tank. Since the wettable powder is present at the bottom of the cold storage tank, the cooled water and the wettable powder efficiently mix and react with each other to form a gas hydrate. The produced gas hydrate rises due to the specific gravity between the water and the wettable powder, and moves to the middle of the water and the wettable powder. Therefore, at the bottom of the cold storage tank, the wettable powder in the tank and the blown-in water are mixed with each other to generate a new gas hydrate. Since the upper layer of water is sucked from above the filter, the gas hydrate generated below the filter can be prevented from entering the heat exchanger, and heat can be efficiently exchanged.

加速される。フィルタは上記請求項(1)の場合と同様、
蓄冷槽内で生成された気体水和物が水と共に吸引されて
熱交換器に入り、熱交換効率を低下させるのを防ぐ。Further, in the structure of claim (2), the upper layer water and the lower layer wettable powder in the cold storage tank are sucked into each to be mixed and cooled, and then blown out to the bottom of the cold storage tank. Since a gaseous hydrate is already generated by water and a wettable powder and is blown out to the bottom of the cold storage tank together with the cooling water, the reaction between the wettable powder at the bottom and water is accelerated. That is, the growth rate of the gas hydrate is accelerated. The filter is the same as in the above claim (1)
This prevents the gas hydrate generated in the cold storage tank from being sucked together with water and entering the heat exchanger to lower the heat exchange efficiency.

２を蓄冷槽１の底部に残して終了させる。During the cold storage operation, that is, when the gas hydrate 5 is produced, the water 3 is sucked by the suction pump 6 from the suction nozzle 8 installed in the upper part of the cold storage tank 1 and sent to the heat exchanger 7. On the other hand, refrigerator 1
The medium cooled by 0 flows through the heat exchanger 7, and the water 3 is cooled by exchanging heat with the medium and is dispersed to the dispersion nozzle 9
Blow off to the bottom of the cold storage tank 1. The blown-out water 3 reacts with the wettable powder 2 existing in the lower part of the cold storage tank 1, and forms a gas hydrate 5 with the seed crystal 4 as a crystal nucleus. The water 3 remaining without reaction and the produced gas hydrate 5 have a low specific gravity and thus rise. The water 3 is sucked again. The gas hydrate 5 accumulates near the middle of the water 3 and the wettable powder 2. When the cold storage operation is continued, the amount of the gas hydrate 5 increases, but most of the cold storage tank 1 is used by the filter 16.
Since the gas hydrate 5 is accumulated in the inside, the gas hydrate 5 is efficiently attached to the heat exchanger 7, the suction nozzle 8, the dispersion nozzle 9, and the suction pump 6 without clogging, so that the heat exchange can be efficiently performed. The cold storage operation is terminated while leaving some of the wettable powder 2 at the bottom of the cold storage tank 1.

It is left to cool in the heat source side heat exchanger 14, is warmed up, and is blown into the regenerator 1 from the dispersion nozzle 13. Warmed water 3
Is cooled by exchanging heat with the gas hydrate 5, and again sucked by the suction pump 11. The gas hydrate 5 decomposes into a wettable powder 2, water 3, and seed crystals 4. The wettable powder 2 and seed crystals 4 having a larger specific gravity than the gas hydrate 5 settle, and the water 3 collects in the upper part. By continuing the cooling to the air conditioner 15, all the gas hydrates 5 in the cold storage tank 1 are decomposed and the cooling operation is ended.

ず、きわめて効率的な蓄冷装置が得られる。As described above, according to the present embodiment, water is sucked from the upper layer of the cold storage tank, cooled by the heat exchanger, and blown out to the bottom of the cold storage tank where the wettable powder is accumulated. The gas hydrate formation is accelerated by accelerating the mixed contact with the agent, and the gas hydrate generated at the bottom is filtered by the filter to prevent it from entering the upper suction nozzle, so that the suction nozzle is not wet. At the same time, the problem of entering the cooler and hindering heat exchange does not occur, and an extremely efficient regenerator can be obtained.

する。The particulate seed crystals 31 are settled in the bottom of the cold storage tank 21 in the wettable powder 22. Until the gas hydrate 32 starts to be produced, the seed crystal 31 is sucked and mixed by driving the pump 25 with the water 23 from the pipe 42 in the cold storage tank 21 and the wettable powder 22 from the suction nozzle 43, respectively, and the refrigerator 30. When the mixed liquid temperature is about 8.5 ° C. or lower, the gaseous hydrate 32 starts to be formed. This is detected by the gas hydrate detection sensor 45, the operation controller 46 closes the electromagnetic valve 26, sucks the water 23 only from the pipe 42, and cools it by the cooler 24. Since the wettable powder 22 is partially contained in the water 23, the gas hydrate 32 is also generated in the cooler 24. By releasing this into the wettable powder 22 and the seed crystal 31 in the lower part of the cold storage tank 21, the gas hydrate 32 is continuously produced. The gas hydrate 32 accumulates near the interface 34. The water remaining after the formation of the gas hydrate 32 moves to the interface 34 and the upper part of the gas hydrate 32 layer. When the amount of gas hydrate 32 produced increases, the interface 3
Although the value of No. 4 continues to decrease gradually, the cold storage operation is terminated while leaving a small amount of the wettable powder 22 at the bottom of the cold storage tank 21. Next, during the cooling operation, that is, when the gas hydrate 32 is decomposed, the heat source side heat exchanger 2
The decomposed gas hydrate 32, which is left to cool to the air conditioner 28 via 9, decomposes into a wettable powder 22, water 23, and seed crystals 31.
