[0005]

Since the conventional ice heat storage device is constructed as described above, when the supercooled water discharged from the supercooled water discharge port 5 is received by the gutter-type supercooled state releasing device 6. Since the water speed drops, the release of the supercooled state may be delayed,
It is difficult to release it, so increase the rough surface zone 9,
It is necessary to configure the gutter-type subcooling state releasing device 6 in two stages, and in the first rough surface zone 9, the fine ice that has deposited adheres to this portion and grows, The subcooling state release device 6 reaches the position of the arrow 10 of the subcooling water intrusion direction and the subcooling water directly drops into the heat storage water tank 1, or ice grows to the supercooling water discharge port 5, and the water cooler There was a problem such as freezing inside 2.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain an ice heat storage device that releases a stable and supercooled state quickly and reliably.

[0007]

The ice heat storage device according to the present invention is configured such that water is supplied from a heat storage water tank via a pump to a cooler equipped with a subcooler that generates supercooled water of 0 ° C. or less. The generated supercooled water is discharged in the horizontal direction, the discharged supercooled water is received almost vertically by the rough surface provided, and the impact force releases the supercooled water from the supercooled state to stabilize it. A supercooled state releasing device that turns into slurry ice is provided, and the slurry ice dropped from the supercooled state releasing device is stored in a heat storage water tank.

[0008]

In the ice heat storage device according to the present invention, the supercooled water having a high water velocity discharged horizontally from the ice cooler collides with the rough surface arranged substantially vertically, so that the impact force at that time also becomes large, The cooling state is released early.

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing an overall view of an ice heat storage device according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a supercooled state releasing device of the present invention. In FIG. 1, 1 is a heat storage water tank for storing slurry ice, 2 is a water cooler, which is communicated with a compressor 7 and a condenser 8 via a refrigerant pipe 17, and is constantly pumped by a pump 3 via a pipe 18. The water supplied from the heat storage water tank 1 is generated as supercooled water of 0 ° C. or lower through the heat transfer tube 4. Reference numeral 12 denotes a discharge hose that horizontally discharges the supercooled water from the water cooler 2, and reference numeral 13 denotes the supercooled water received by a rough surface arranged substantially vertically, and the impact force releases the supercooled water from the supercooled state.

On the rough surface of the wire net 15 of 10 mm square attached to the rectangular plate 14 of the supercooling state releasing device 13, the supercooling water having a high water speed releases the supercooling state by its impact force, and the fine ice is removed. It precipitates, becomes ice-water slurry, and is discharged in the direction of arrow 11. Also, fine ice attached to the 10 mm square wire net 15 grows in the direction of the supercooled water discharge hose 12, but falls in the direction of arrow 11 due to its own weight and water pressure. This state is continuously repeated to store the ice-water slurry in the heat storage water tank 1.
