Description

ICE CONTAINER FOR THERMAL STORAGE APPARATUS}

The present invention relates to a freezing container of an ice storage device, and more particularly, is formed integrally with the freezing container, and efficiently distributes ice expansion and ice shrinking of the freezing container, thereby reducing fatigue and preventing breakage and enlarging the heat transfer surface. And an opening groove having a brine flow path and a fixing means capable of easily fixing the ice container in the heat storage tank.

The ice storage device is a system for the purpose of leveling the supply and demand of replacing the peak power consumption for the daytime cooling with the nighttime electricity by storing the ice storage cooling heat using the low-cost late night power and cooling the heat during the daytime.

The ice storage cooling system principle uses a low temperature freezer as an ice making source to cool water up to its freezing point, and the water becomes ice and stores about 80 kcal of latent heat for 1 kg of ice when it is converted from liquid to solid. In contrast, about 80kcal of latent heat of fusion is released when ice is thawed with water, and this latent heat is used in ice storage cooling systems.

In general, the ice storage device is an ICE ON COIL TYPE method of making ice on the outside of the coil, and an ice container that ices and thaws water or PHASE CHANGE MATERIAL, which is the icing liquid filled in the container. ICE slurry type to ice the ice formed using a mixture of additives such as methanol or propylene glycol in the form of slurries, which are fine particles, and to the surface of the ice making plate with refrigerant flowing therein. It is classified as ICE HARVEST TYPE type by releasing ice by spraying water and then recirculating refrigerant gas to ice off ice cubes in ice making plate.

Here, in the ice storage device of the freezing container type, a repetitive action of freezing and thawing the frozen liquid filled in the sealed freezing container is essential. For reference, when water of 0 ℃ is changed into ice, volume expansion of about 9.07% is achieved.

Therefore, the sealed ice container is not only able to avoid the fatigue caused by the volume expansion of the ice making and the shrinking action of the sea ice, but also the accumulation of fatigue eventually leads to breakage of the ice container.

In addition, with the cell (SHELL) of the ice container as a heat conduction part, heat exchange with the brine flowing on the outer surface of the ice container requires heat exchange. The ice container is limited in size, thickness of the cell, and material selection of heat conductivity. The air layer in the freezing vessel, which is formed for the purpose of buffering shrinkage, is also correlated with the deicing and thawing efficiency and causes a buoyancy problem, thereby limiting the expansion of the air layer.

The freezing container manufactured by a simple manufacturing process is a standard product, easy to mass production and supply, easy to operate as a lightweight product, can be installed in any heat storage tank structural conditions, and has advantages over other ice storage methods such as low initial investment cost. On the other hand, a serious disadvantage of the freezing container is the breakage of the freezing container, and it is very difficult to pick out and replace the broken freezing container in a heat storage tank filled with a large amount of freezing container and brine. As a way of solving the fatigue of ice-making expansion and sea ice shrinkage, which are the causes of breakage of ice containers, new products have been developed and supplied to the market, such as corrugated depressions and bends, which absorb expansion and contraction in ice containers. Although the problem of breakage of the freezing container is still generated by expansion and thawing shrinkage, demand evasion is intensifying due to the stability of the product.

10 is a schematic cross-sectional view of a conventional ice container. As shown, the conventional freezing container 100, the filling portion (not shown) is filled with the freezing liquid 113, and a plurality of expansion and contraction to the ice making expansion and thawing shrinkage of the freezing liquid to reduce the freezing damage of the container An expansion thimple 112 and a floc (not shown) for injecting and closing the icing liquid are provided. In addition, unlike the aforementioned ice container 100, the ice container provided with an air layer (not shown) accommodates the ice making expansion by the compression action of the air layer.

As a result, brine supplied for ice making from a freezer (not shown) is continuously recycled through a heat storage tank (not shown) while ice-making liquid is frozen in the freezing container 100 and the ice is phase-changed into ice. Ice making expansion is accommodated by the expansion action of the plurality of expansion dimples 112 configured in the freezing container (100). In addition, the ice container provided with the air layer (not shown) receives the expansion pressure by the compression action of the air layer.

The brine, which absorbs heat from the heat exchanger (not shown) during cooling, flows into the heat storage tank (not shown), and phase-changes the ice in the freezing container to the freezing liquid. During continuous recirculation to the sea ice and ice heat dissipation process is performed, the expansion dimple 112 is contracted by the sea ice to restore the original.

The ice container (not shown) provided with a conventional air layer is generally a structure filled with about 97% of freezing liquid and 3% of an air layer, and the freezing container (not shown) is a heat storage tank filled with brine due to the buoyancy effect of the air layer (not shown). ) To rise on the surface of the water forced the freezing container 100 into the heat storage tank (not shown) using a submerged grating (not shown) or a fixed partition (not shown) of the freezing container (not shown) for forced sedimentation. A sedimentation device is required to settle, and an air layer (not shown) in the ice container (not shown) has an effect of buffering expansion due to ice making, while an air film is formed in the ice container 100 to provide a thermal conduction dead zone and buoyancy. There is a problem that occurs.

In addition, the ice-making expansion and the sea ice shrinkage action are absorbed by the expansion and contraction of the expansion dimple 112, but the weight of the ice container 100 is broken by continuously adding fatigue to the ice container 100, which is usually made of high density polyethylene (HIGH DENSITY POLYETHYLENE). If the freezing container 100 is broken, the brine and the freezer (not shown) flowing in the heat storage tank (not shown) and the ice load may adversely affect the loss of maintenance costs.

Accordingly, an object of the present invention is to provide an ice storage device of an ice storage device capable of efficiently distributing ice expansion and sea ice shrinkage of the ice container to reduce fatigue and breakage.

Another object of the present invention is to provide an ice storage container of an ice storage device capable of enlarging the heat conduction surface of the ice container to improve ice making and thawing efficiency.

Still another object of the present invention is to provide an ice storage container of an ice storage device having a means for fixing the ice storage container into the water surface of the heat storage tank.
