The so-called ice storage method stores cold heat in the form of latent heat by storing ice in a heat storage water tank for air conditioning.Due to the difference in ice making methods, the form of ice stored is either solid (ice blocks) or liquid (fine ice). There is a state in which ice is suspended in water). Both methods have their advantages and disadvantages, but the applicant has already filed Japanese Patent Application No. 62-47770 and Patent Application No.

No. 228800, Japanese Patent Application No. 62-245930, etc., by producing supercooled water cooled to below zero degrees Celsius as a continuous flow, and instantly releasing the supercooled state of this continuous flow of supercooled water. We proposed an invention to produce liquid ice suitable for heat storage in which fine ice is dispersed.

The present inventors previously proposed in Japanese Patent Application No. 62-271922 that if the temperature of the tube wall in contact with water of the heat transfer tube is controlled to a temperature that does not fall below -5.8℃ (but below zero degrees Celsius), the Reynolds of water flow can be reduced. It was revealed that supercooled water can be produced continuously regardless of the number (ie, flow rate and pipe diameter), water temperature before cooling, water temperature after cooling, etc. However, if the fluid pressure of the water flowing into or exiting the heat transfer tube changes suddenly, air vesicles may occur. When these bubbles are generated, the presence of the bubbles acts to release the supercooled state of the generated supercooled water, causing ice to precipitate, which may cause freezing within the heat exchanger tube or at the outlet of the heat exchanger tube.
In this case, not only will the objective of releasing the supercooled state at the intended position and obtaining fine ice be not achieved, but the heat exchanger tubes will freeze, resulting in an inoperable state.

FIG. 1 shows an overall equipment layout diagram showing an embodiment of the device of the present invention, in which 1 represents a heat storage water tank, 2 represents a group of heat exchangers that handle the air conditioning load, and a circulating pump 3 The heat source water in the heat storage water tank 1 is circulated to the heat exchanger group 2 for heating and cooling. In the cooling season such as summer, this device generates ice by using electricity at night, and uses the latent heat of the ice to store a large amount of cold heat in the heat storage water tank 1, in preparation for the peak load during daytime cooling. However, in order to make this ice, a continuous flow of supercooled water was created by the water cooler 4, and by instantly releasing the supercooled state of this supercooled water, fine ice was precipitated. A so-called sherbet-like ice-water slurry is stored in heat storage water tank 1.

除装置が存在していてもいなくてもよい。 The water cooler 4 used in this invention is a rigid shell 5
By dividing the inside with partition plates 6 and 7, a water inlet header part 8, a cooling chamber 9, and an outlet header part 10 are formed from the bottom, and a large number of heat exchanger tubes 1 with open ends are formed.
1 is passed through the partition plates 6 and 7 so that one end opens into the water inlet header part 8 and the other end opens into the outlet header part 10, and the substantial length thereof is inside the cooling chamber 9. The device is designed to fit in the vertical direction. A water supply port 12 is provided in the water inlet header section 8 and a supercooled water outlet 13 is provided in the outlet header section 10 to allow water to flow through the heat transfer tubes 11 from the bottom to the top. In this example, the cooling chamber 9 functions as an evaporator of the refrigeration cycle, and cools each heat transfer tube 11 from the outside by evaporating and expanding the refrigerant here. The refrigeration cycle includes this cooling chamber 9, which functions as an evaporator, a compressor 14, a condenser 15, and an expansion valve 1.
6 and refrigerant piping. At that time, by installing the inlet 17 for high-pressure refrigerant liquid into the cooling chamber 9 at the lower side and the outlet 18 for taking out the evaporated refrigerant from the cooling chamber 9 at the upper side, the evaporation of the refrigerant is prevented in the cooling chamber 9. Since the temperature becomes lower toward the top, the water flowing through the heat exchanger tube 11 becomes lower toward the outlet thereof, and a preferable temperature distribution for producing supercooled water is obtained. The supercooled water cooled to below zero degrees Celsius by flowing through the heat exchanger tubes 11 is taken out as a continuous flow from the outlet header 10,
This is released from the supercooled state by the supercooling release device 20 to become a mixed fluid of fine ice and water, and then supplied to the heat storage water tank 1 . The supercooling release device 20 is one that applies mechanical energy to the supercooled water, one that applies cold energy at a lower temperature, one that applies ultrasonic vibration, or the like. Note that the supercooled state can also be released in the heat storage water tank 1, and in this case, a method using falling energy of supercooled water colliding with the water surface of the water tank, an ultrasonic application method, or agitation using a rotary blade may be used. There are other methods, such as a method in which further forced cooling is performed using an in-tank cooler. Therefore, water cooler 4
The return path 19 from the heat storage water tank 1 to the heat storage water tank 1 may or may not include a supercooling release device.

を回避することができる。 In the device of the present invention, a part of the water in the heat storage water tank 1 is passed through the water supply path 21 to the water cooler 4 by the circulation pump 3 during the cooling operation in the cooling season of the building or when the cooling operation is stopped at night. A header tank 22 is interposed in this water supply path 22 to supply water. This header tank 22 is installed at a position higher than the installation position of the water cooler 4,
The water pumped into the header tank 22 is allowed to fall into the water cooler 4, and its potential energy is used to flow the water downward or upward through the heat transfer tubes 11 of the water cooler 4. A liquid level regulator 23 is attached to the header tank 22, and an overflow pipe 24 is provided to maintain the water level 25 in the header tank 22 at a predetermined level during operation. As a result, the water pulsation caused by the circulation pump 3 is absorbed by the header tank 2, and a steady water flow at a constant pressure is supplied to the water cooler 4, and the water flow rising inside the heat transfer tube 11 is also in a steady state. is maintained. Therefore, it is possible to completely eliminate the generation of bubbles in the water flowing up the heat transfer tube 11 or in the outlet header section 10 or the supercooled water outlet 13, and it is possible to avoid the supercooling cancellation phenomenon due to the presence of bubbles. .

I can do it. This cooler 27 shares a refrigeration cycle with the water cooler 4, and for example, the water cooler 4 and its expansion valve 14 and the cooler 27 and its expansion valve 28 can be connected in parallel in the illustrated refrigerant piping.

According to the present invention, by providing a header tank and having a structure in which water is passed from bottom to top inside the heat transfer tube, pulsation and sudden pressure changes can be avoided during continuous production of supercooled water by a water cooler. A steady state water flow can be flowed through the heat transfer tube without causing heat transfer, and this prevents the generation of bubbles inside the heat transfer tube and at its outlet, and the presence of bubbles suppresses the operation to release the supercooled state. Therefore, freezing inside the water cooler and freezing at the outlet of the water cooler can be prevented. Therefore, it is possible to stably and continuously supply supercooled water to the intended position for releasing the supercooled state, and it is also possible to prevent troubles due to occurrence of freezing within the piping system. And the device for this can be constructed very simply and inexpensively. Therefore, it is useful for stable operation of an ice making device for making sherbet-like ice and storing it in a heat storage tank.
