The present invention relates to an ice storage system, and more particularly, to an ice storage system capable of more efficiently cooling by increasing the thermal conductivity efficiency of the ice storage coil used in the ice storage system.

Ice storage system is to freeze the ice using energy, such as midnight electricity, and to cool the cooling load of the interior or home of the building by using the ice of the ice, as shown in FIG. 10), a refrigerator (20) and a heat exchanger (30).

The ice storage tank 10 is a configuration for freezing the cooling water therein by using a late-night electricity, as shown in Figure 2, the casing 11, the heat-insulating waterproof layer 12, the ice storage coil 13 and the coil Frame 14 and cooling water.

The casing 11 is a member surrounding the outermost circumferential surface of the ice storage tank 10.

The heat insulating waterproof layer 12 is accommodated in the casing 11 and is generally composed of a heat insulating material and a waterproof layer.

The ice-cold coil 13 is arranged in the state supported by the coil frame 14 in the heat insulation waterproofing layer 12, and the cooling water is frozen by the cool air of the refrigerant flowing in the ice-cold coil 13. It becomes.

The refrigerator (20) is configured to cool the cooling water by flowing a refrigerant in the ice-shaft coil (13), and the heat exchanger (30) is configured for heat exchange between the cooling water and the cooling load (40).

In this conventional ice storage system, as the ice storage coil 13, a pipe made of steel or polyethylene (PE) is used. 3 illustrates a state in which a coolant ice 15 is formed around a conventional ice shaft coil 13.

The PE pipe has the advantage of being light, but it has the disadvantage of being inefficient due to lower thermal conductivity than the steel pipe. On the contrary, the steel pipe is superior to the PE pipe but is difficult to install or manufacture. There was a point.

Meanwhile, even in the case of steel pipes, thermal conductivity is superior to that of PE material, but there is a limit to construct an efficient ice storage system, not a material having excellent thermal conductivity.

The present invention has been made to improve the above-mentioned problems, and an object thereof is to provide an ice storage system capable of more efficient ice storage by improving the ice storage coil.

In order to achieve the above object, the present invention,

An ice storage tank comprising an adiabatic waterproofing layer, an ice storage coil installed inside the adiabatic waterproofing layer, and a cooling water accommodated in the adiabatic waterproofing layer, a refrigerator for cooling the cooling water by flowing a refrigerant through the ice storage coil, the cooling water and the cooling load. In an ice storage system including a heat exchanger for heat exchange of

The ice-coiled coil,

It provides an ice shaft system comprising a tube member which is an elliptical cross-section pipe made of aluminum and a wing member protruding from the outer circumferential surface of the tube member and extending in the axial direction of the tube member.

The wing member is preferably provided with a pair at intervals of 180 degrees.

More preferably, the inner circumferential surface of the pipe member is formed with a plurality of uneven grooves along the inner circumferential surface.

Hereinafter, with reference to the drawings will be described in detail a preferred embodiment of the present invention.

The ice storage system according to the present embodiment includes an ice storage tank 10, a freezer 20, and a heat exchanger 30 like the ice storage system illustrated in FIG. 1. As shown in FIG. 5, the ice storage tank 10 includes a casing 11, a heat insulating waterproofing layer 12, an ice storage coil 13, a coil frame 14, and cooling water.

Most of the configuration of the ice storage tank 10, and the configuration of the refrigerator 20 and the heat exchanger 30 is the same as the configuration corresponding to the conventional ice storage system shown in Figure 1, the following is a characteristic configuration of the present invention Only the engraving shaft 13 will be described. Although the ice shaft coil 13 shown in FIGS. 2 and 3 and the ice shaft coil 13 shown in FIGS. 4 to 6 have different configurations, the same reference numerals are used for convenience.

Ice-shaft coil 13 according to this embodiment consists of a tube member 131 and the wing member 132.

The pipe member 131 is made of aluminum. Aluminum material has an excellent thermal conductivity compared to the conventional steel or PE material, but is a very light material compared to the steel material, so there is an advantage in manufacturing or transportation.

The pipe member 131 has an elliptical cross-sectional shape, and has an effect of increasing the heat transfer area compared to the circular shape. The cross-sectional shape of the elliptical shape should be understood as a concept including both a circular elliptical shape that is a physical ellipse rather than a mathematical elliptical shape, and may be expressed as an oval shape rather than an ellipse in English.

The wing member 132 protrudes from an outer circumferential surface of the pipe member 131 and extends in the axial direction of the pipe member 131, and a pair is provided at intervals of 180 degrees.

The inner circumferential surface of the pipe member 131 is provided with a plurality of uneven grooves 133 along the inner circumferential surface, thereby increasing the heat transfer area of the refrigerant flowing through the inner circumferential surface of the pipe member 131 so that more efficient heat transfer can occur. .

6 shows a state in which the cooling water ice 15 is formed in the cooling coil 13 described. Compared to the cooling water ice 15 formed in the conventional cooling coil 13 shown in FIG. 3, the cross-sectional area thereof is larger, which may be interpreted as the cooling water ice 15 is formed around the wing member 132. It can be seen to show greater ice storage efficiency.

This has the advantage of reducing the size of the insulation layer required to store the same ice storage heat compared to the existing ice storage system, and thus the installation of the ice storage tank required to store the same amount of heat (cold air) compared to the existing ice storage system There is also the advantage of reducing the area.

In the above description, an embodiment in which a pair of wing members are provided at intervals of 180 degrees has been described. However, the number of wing members and the spacing between the wing members are not necessarily included in the technical spirit of the present invention only when the same as the described embodiments. Modifications should also be considered to be included in the technical spirit of the present invention.

In the above description of the embodiment in which the uneven groove is formed on the inner circumferential surface of the pipe member, even if the uneven groove is not formed, the object of the present invention can be achieved, and such modifications are included in the technical spirit of the present invention. Must see

Although a preferred embodiment of the present invention has been described above, the technical idea of the present invention is not limited, and may be implemented as various types of ice storage systems within a range that does not violate the technical idea of the present invention.

As described above, according to the present invention, by improving the ice storage coil, it is possible to provide an ice storage system that is more efficient, lighter and more compact.
