The water cooler 3 and the compressor 5 of the refrigeration cycle, the condenser 6,
It is composed of a decompression device 7. Reference numeral 8 is a pump for sending the cooling water in the heat storage water tank 1 to the water cooler 3, and 9 is a water supply pipe line.
10 is a discharge port of the cooling pipe 4, 11 is a discharge flow of supercooled water, 1
2 is a box-shaped supercooling releasing device which is arranged in front of the refrigerator 2 (on the right side of the drawing) on the heat storage water tank and has an opening 13 and a bounce prevention edge 14 on one side, and the other of the openings 13 is It is a supercooling release plate 15 against which cooling water collides. Reference numeral 16 is a heat exchanger that performs heat exchange using the cooling water in the heat storage water tank 1 and returns the cooling water that has undergone heat exchange and has increased in temperature to the heat storage water tank 1 again, and 17 sends the cooling water through the pipelines 18 and 19. It is a pump.

Next, the operation will be described. First, the water or the aqueous solution in the heat storage water tank 1 is sent to the water cooler 3 by the pump 8 through the water supply pipe line 9, the liquid is cooled by the refrigerator 2, and is kept in a liquid state in a supercooled state at a temperature below the melting point. Liquid, that is, supercooled water. Then, this supercooled water is discharged from the discharge port 10, becomes a discharge flow 11, collides with the supercooling release plate 15 of the supercooling release device 12, and the supercooled state is released, and slurry ice (ice crystals) is released. Will be deposited. The slurry-like ice generated in this way falls into the heat storage water tank 1 and is retained and accumulated.

[0004]

Since the conventional ice heat storage device is configured as described above, a part of the slurry ice crystals released from the supercooled state adheres to the supercooling release plate and grows. However, the entire supercooling releasing device gradually freezes, and finally reaches the discharge port to be in a closed state, and continuous ice making cannot be performed. Therefore, deicing work is always required. Further, since the falling positions of the ice crystals are concentrated in almost one place, there is a problem that the ice crystals are naturally accumulated in a mountain shape in the accumulation water tank, and the worker sometimes needs to flatten the work.

The present invention has been made in order to solve the above-mentioned problems and eliminates the need for a supercooling releasing device,
Therefore, it is an object of the present invention to obtain a simple and efficient ice heat storage device that does not require the troublesome work such as deicing.
