る。2. Description of the Related Art In recent years, in relatively large-scale air conditioning systems in industrial plants, buildings, and the like, there are many examples in which heat storage air-conditioning equipment that uses cheap night electricity is introduced. This is because both the supply side and the customer side, such as stable power supply and economical operation of the air conditioning system, are achieved by reducing power demand during peak daytime air-conditioning loads and using power during low-price night off-peak times. Can also meet the social demands such as the benefits of the above, and the suppression of carbon dioxide gas generation.

る）方式が主流となりつつある。By the way, in this type of air-conditioning heat storage system, an ice heat storage device which is excellent in safety and economical efficiency is known for a cooling load in summer. In particular, in the ice heat storage system that emphasizes ice-dissolving ability, the ice-making process is devised so that sherbet-like ice and fine ice particles are formed and floated in the water tank, and the warmed water after absorbing the cooling load is warmed up. The method of melting ice by refluxing and mixing it (generally called the dynamic method) is becoming the mainstream.

冷熱を得る構成としたものである。Conventionally, as an example of a heat storage air-conditioning system adopting such an ice heat storage system, Japanese Patent Laid-Open No. 4-2360 has been proposed.
32 and JP-A-3-140767. None of these devices dissolve in water or aqueous solutions,
And, after cooling the antifreeze liquid having a specific gravity larger than that of water and a freezing point of 0 ° C. or less, it is mixed with water or an aqueous solution for direct heat exchange, and at the time of mixing, a part of water is made into fine ice and stored, By defrosting this when cooling demands,
It is configured to obtain cold heat.

It may be carried. As a result, the diameter of the water supply pipe can be reduced and the transportation power can be reduced.

う不具合が生じる。However, in the conventional ice heat storage system adopting these direct contact ice making methods, the water-insoluble high specific gravity antifreeze liquid (hereinafter referred to as antifreeze liquid) used is sprinkled on the produced sherbet-like ice, and a part thereof Is left inside the ice, and the apparent specific gravity becomes larger than that of water, causing the problem of sedimentation.

合がある。For this reason, it is desirable that the position of the outlet of the antifreeze liquid is in the lower part of the water tank as much as possible, and it is necessary to devise so that the formed ice quickly moves from the drop passage of the antifreeze liquid.
For this reason, a sufficient antifreeze drop distance cannot be maintained if the water tank has a relatively small capacity, or if the installation area is not sufficient and the shape of the water tank is relatively high, or if the water tank has a shallow depth. In some cases, it may not be possible to use the direct contact type ice heat storage system because it is difficult to form convection.

の吹出し部より上部に氷を溜める必要がある。As described above, the conventional ice heat storage system adopting the direct contact ice making method is excellent in ice making efficiency, deicing property, usability, etc., but the ice is formed above the blowing portion of the antifreeze liquid. It is necessary to store.

発生する。Therefore, it is not possible to store sufficient ice in a shallow water tank. Further, if the tufted ice generated in the flow of antifreeze falling in water is captured, a problem occurs such that ice containing heavy antifreeze is accumulated at the interface between water and antifreeze.

From below the freezing point below the freezing point and the antifreeze liquid having a temperature above the freezing point into the mixing tube, and by blowing out water from the outlet of the outermost circumference, forming a curtain of water and contacting the low temperature antifreezing solution with the wall surface. This prevents the formation of ice on the wall surface of the mixing tube to block the flow path, and when the antifreeze liquid flows down to some extent, the antifreeze liquid drops almost vertically, making it difficult for it to come into contact with the wall surface. Moreover, since the temperature also rises, the clogging of the flow path with ice does not occur.

が吹出し口１２ｃより流出している。Next, the operation of the ice heat storage device configured as described above will be described. Now, assuming that the ice making operation is being performed, the antifreeze liquid 4 cooled to below freezing point by the refrigerator 13 flows into the mixing pipe 3 through the outlet 12a and is mixed with water. At this time, the antifreeze liquid having a temperature slightly higher than 0 ° C. is blown out by the pump 15 through the pipe 14b.
It flows out so as to surround the antifreeze liquid 4 having a temperature lower than 2a,
In addition, water having a relatively high blowing speed flows out around it from the blowing outlet 12c.

垂直に流下する。The low-temperature antifreeze liquid thus flowing out from the outlet 12b is the antifreeze liquid 4 flowing out from the outlet 12b.
Heat exchange with surrounding water while descending underwater with. The descending water and the antifreeze liquid have a relative velocity with each other when descending to some extent, but have a constant velocity, and flow down vertically inside the mixing tube 3.

０℃の状態のまま不凍液は０℃まで昇温される。In this case, the water is cooled by the antifreeze, and the precipitation of ice is observed in part. In this way, the cold heat of the antifreeze solution is stored as the heat of solidification of ice, and the antifreeze solution is heated to 0 ° C while the water temperature remains at about 0 ° C.

氷が混合管３の内部で形成されることはない。In this way, ice making is performed inside the mixing tube 3, but because of the downward flow of water and antifreeze, the ice particles flow down independently of each other, and the ice of cotton candy as in the conventional case flows. It is not formed inside.

混合管３は水槽形状によらず、十分長い距離を取ること
が可能であり、十分な熱交換を達成することができる。The flow of water containing ice that has descended to the bottom of the mixing pipe 3 is converted from the vertical direction to the horizontal direction by the connecting portion 8 with the water tank 1, and is smoothly guided to the water tank 1. Therefore,
The mixing tube 3 can have a sufficiently long distance regardless of the shape of the water tank, and can achieve sufficient heat exchange.

In this case, the ice stored in the upper part of the water tank 1 is prevented from being sucked from the water intake 10 by the wire net 11, and floats in a form of widely covering the water surface.

て蓄積するようにしたことを特徴とする氷蓄熱装置。6. A water tank in which water is stored, and a bottom portion is provided with a recovery portion for recovering an antifreeze liquid having a specific gravity larger than that of water, water insolubility, and a freezing point lower than a freezing point, and a longitudinal portion of the water tank. A mixing tube inserted with the direction vertical,
A triple-structured nozzle provided at the uppermost part of the mixing pipe, having a first outlet on the innermost peripheral side, an annular outlet around it and an annular or multiple outlets on the outermost peripheral side, and the recovery section. A first antifreeze circulation system that collects the stored antifreeze liquid, cools it below the freezing point by a refrigerator, and causes it to flow into the mixing pipe through the first outlet of the nozzle; A second antifreeze circulation system for flowing the antifreeze liquid at a temperature into the mixing pipe from the second outlet of the nozzle, and water taken from the upper part of the water tank into the mixing pipe from the third outlet of the nozzle. A low-temperature water circulation system for flowing out, and a water-blowing nozzle for ejecting low-temperature water horizontally into the water tank together with water, which is connected to the low-temperature water circulation system and flows into the water tank through a lower opening of the mixing pipe. The mixing tube is made to flow down the antifreeze liquid at a constant speed by the antifreeze liquid and water flowing from the nozzle of the triple structure to make a part of the water, and the ice is sherbet-shaped at the upper part of the water tank through the lower opening.
