The present invention relates to an ice storage container for an ice storage system, and more specifically,
A container body which forms a hollow filling part in which freezing liquid is filled; A coupling tool formed integrally with the container body, and formed of a filling hole formed along an inner circumferential surface, an airtight surface formed on an upper end portion, and a screw portion formed along an outer circumferential surface; A rupture member coupled to the coupler and rupturing during excessive freezing expansion to prevent breakage of the ice storage container; A sealing part that is hermetically coupled between the hermetic surface and the rupture member and is accommodated in the container body, and forms an extrusion port for transmitting a crushing expansion pressure to the rupture member; It relates to an ice storage container for an ice storage system, characterized in that it comprises an expansion and contraction portion having a sealed expansion and contraction space restored to the original shape, and a support portion formed integrally between the sealing portion and the expansion and contraction portion.

This system aims to equalize the supply and demand of ice cooling heat storage system by replacing late-night cooling peak power consumption with midnight electricity by storing latent heat by freezing the freezing liquid using inexpensive midnight surplus power and using this heat for cooling during the day. to be.

The principle of ice heat storage cooling system is to use a freezer as a freezing heat source to cool the freezing point while flowing the refrigerant. The freezing liquid becomes ice and stores about 80 kcal of latent heat for 1 kg of ice when it is converted from liquid to solid. On the contrary, about 80kcal of latent heat is released even when ice is thawed with water, and the latent heat is used in the ice storage cooling system.

In general, an ice on ice system (ice on coli type) that freezes the ice storage system on the outside of the coil, and ice or ice container method (ice ice and ice) that freezes and thaws water or phase change material, which is the ice liquid filled in the ice storage container. container slurry) and an ice slurry type in which ice formed by using an ice-cold liquid mixed with an additive such as methanol or propylene glycol is formed into a slurry of fine particles, and a surface of a frozen plate through which refrigerant flows. After spraying water on the ice to icing the ice, the refrigerant gas is reversely circulated, and it is classified into an ice harvesting type (ice harvest type) in which the ice is removed in the form of ice from the freezing plate.

Here, in the ice storage system of the ice storage container type, a repetitive action of freezing and thawing the frozen liquid filled in the sealed ice storage container is essential.

For reference, when the water at 0 ℃ is frozen (phase change) with ice, a volume (thermal) expansion of about 9.07% is achieved.

Therefore, the ice storage container usually made of high density polyethylene (SHELL) has a thickness of 1.5 ~ 2mm usually due to the nature of the thermal conductivity, so if the sealed ice storage container does not accommodate the volume expansion pressure due to freezing If the volume expansion of the ice and the shrinking action of the ice are not absorbed efficiently, the ice storage container is damaged due to excessive accumulation of fatigue.

However, ice storage containers, in the freezing and thawing action, have to heat exchange with refrigerant flowing through the outer surface of the ice storage container using the body as a heat conduction portion, and thus the material having the size of the container, the thickness of the body and the thermal conductivity and pressure resistance. Limited in selection, the air layer in the ice storage container formed to buffer the freezing expansion pressure also insulates the body directly between the contacting body and the freezing liquid, reducing the freezing and thawing efficiency (ie, lowering the heat exchange efficiency per unit heat transfer area of the body). In addition, the expansion of the air layer is also limited by reducing heat storage and buoyancy problems.

Ice storage container manufactured by simple manufacturing process is a standard product, easy to mass production and supply, easy to work 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, the serious drawback of ice storage containers is the breakage of ice storage containers, and it is almost impossible to identify, pick out and replace broken ice storage containers in a storage tank filled with a large amount of ice storage containers and refrigerants. There is a difficulty in emptying and identifying and replacing broken ice storage containers with the naked eye.

As a method for reducing the ice expansion and thawing shrinkage, which are the causes of breakage of ice containers, new products have been developed such as the formation of corrugated depressions, bends, spiral protrusions, etc., which absorb expansion and contraction in ice containers. The change of the shape of the body alone is not effective in absorbing ice expansion and sea ice shrinkage, so the breakage problem of ice storage containers is not fundamentally solved.

In addition, conventional ice storage containers form a buffer air space corresponding to approximately 10% of the ice storage container volume as a means of alleviating (freezing) the ice expansion, and the body portion of the ice storage container facing the air space has a freezing liquid. It is caused by heat insulation and heat exchange efficiency, as well as reducing heat storage rate and buoyancy problems.

In addition, conventional ice storage containers have a problem in that the heat exchange properties of the ice and ice are low in the center of the ice storage container spaced apart from the body by freezing and thawing through a body forming a hollow outer shell.

In order to solve the problems of the conventional ice storage container, the invention "Ice-freezing container for ice storage system" is disclosed in the patent application No. 10-2004-0090887 (2004. 10.27) of the applicant of the present invention on April 18, 2003 Known by

Figure 3 is an enlarged partial cross-sectional view and the main portion enlarged sectional view of a conventional ice container. As shown, the hollow freezing container 100 having a filling part is a substantially rectangular cylindrical structure having curved corners, the partition wall 121 integrally with the body 110 in a horizontal direction from the center of the body 110. A plurality of through holes 120 and a plurality of circumferential protrusions 113 formed integrally with the periphery of the body 110 to provide a brine flow interval on the outer surface of the ice container and stretched to ice and sea ice 113. And a plurality of vertical protrusions 114 which are formed integrally with the circumferential protrusion 113 and maintain a distance between the icing vessels 100 and provide a seating portion, and are integrally formed with the rear body of the body 110. Filling holes 131 are formed through the plurality of side protrusions 115 and the one side body 120 of the body 110 to maintain the gap between the freezing container 100 and the protective cap on the filling hole 131 130 and the front end surface of the filling port 131 and the lower of the coupling cap 134 It is provided between the surfaces, which is airtightly coupled by screwing the coupling cap 134, has a lower pressure resistance than the icing container, is formed along the outer circumferential direction of the hemispherical expansion and expansion portions provided in the center, and is integrally formed as a gasket. The elastic member 132 and the coupling cap 134 is formed in the center of the upper surface, and the elastic member 132 is characterized by the configuration of the opening and exit along the expansion path 133.

By this configuration, the ice container 100 loaded in the heat storage tank is brine which is introduced through the brine inlet and recycled to the heat exchanger and the freezer through the brine outlet, and the outer surface of each ice container and the protrusions 113, 113a, 114, and 115. ) And freezing liquid in the freezing container 100 while flowing evenly through the through-hole 120.

In addition, the expansion pressure is increased by the ice making of the ice container 100, and each of the protrusions 113, 113a, 114, and 115 gradually expands in both directions by the expansion pressure. When the expansion of each of the protrusions 113, 113a, 114, 115 reaches a limit, the expansion and contraction member 132 in the protective cap 130 is expanded outward to relieve the expansion pressure in the freezing container 100.

Subsequently, when the heat dissipation process is used to use the ice storage heat of the icing container 100, the ice is thawed in the icy container 100 and each of the protrusions 113, 113a, 114, and 115 expanded and contracted with the reduced pressure resistance. Is contracted and restored to its original state.

When the pressure exceeds the expansion limit of each of the protrusions 113, 113a, 114, 115 and the expansion and contraction member 132, the excessive expansion pressure that causes breakage of the freezing container 100 has a lower pressure resistance than the freezing container 100 The expansion and contraction member 132 ruptures and transmits the pressure in the freezing container 100 to the outside to prevent breakage of the freezing container 100.

Therefore, it improves the freezing amount and heat exchange efficiency of the freezing container, effectively distributes the ice making expansion and sea ice shrinkage, suppresses the reduction of fatigue and breakage, and it is easy to fix the freezing container in the heat storage tank to solve the problem of injury and deflection caused by buoyancy. There is an effect that the reduction and maintenance costs can be reduced.

By the way, the ice container for ice heat storage systems disclosed in the above-mentioned Patent Publication No. 10-2004- 0090887, the outward expansion of each of the protrusions (113, 113a, 114, 115) having a '자' shape during expansion and expansion, The member 132 has a structure in which it expands outward along the expansion path 133 and its expansion action, and only the expansion of each protrusion 113, 113a, 114, and 115 and the expansion member 132 is normally sealed. There is a limit to absorbing approximately 10% of the volume expansion generated when the ice buffer buffered in the ice is frozen, there is a need to further form a predetermined buffer air space in the ice container 100.

And the elastic member 132 of the original "∪" shape is a structure that is expanded outwards in the "결" shape while being bent 180 degrees when frozen ice expansion, the action switching unit in accordance with the repetition of the outward expansion and the original restoration action There is a need to improve the structure by weakening the durability of the edges in contact with the airtight part.

In addition, when the freezing expansion is bent by 180 degrees, the expansion and contraction of the expansion member 132 "extracted outward in the shape of" ∩ "and other tightly stacked container is generated to implement the elastic member that absorbs the freezing expansion limited in size This raised the need for improvement.

In addition, in the detailed description, when the expansion and contraction member 132 is ruptured, the bursting state of the expansion and contraction member 132 is easily brought out to display the bursting state, and the expansion and contraction member 132 or the coupling cap 134 and It is disclosed that the display section leading to the connecting string, etc. can be laid, in claim 3, "protective cap, characterized in that it further comprises a display section for indicating the state of rupture is drawn out when ruptured" Constrained by the construction of the display section so as to protrude outward when ruptured in the "∪" shaped expansion and contraction member, which is caused by the action of freezing expansion and thawing shrinkage along the expansion path formed in the small diameter coupling sphere. Is buried in the body of the flexible elastic member or a fixed groove formed on one side of the elastic member), and the structure of the small size to improve the structure according to the constraints in manufacturing the display sphere having an air space therein The importance were raised.
