Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling system,

The present invention relates to a cooling system having a variation in brine cooling temperature of an ice link, wherein the brink cooling temperature-dependent variable of the ice link is controlled to control the brine high or low flow in the cooling mat according to the brine set freezing point temperature condition To a cooling system having a cooling system.

In recent years, as the interest in leisure has increased, skating, which has been generally recognized only as a winter movement, is being carried out in the four seasons, and it is becoming widespread as a popular movement.

As a result, the construction of indoor ice link, which is a place for skating, is increasing, but the technology for design tends to be not widely known so far due to the number of indoor ice links constructed in Korea.

Such an ice link is divided into an indoor ice link installed indoors and an outdoor ice link installed outdoors according to installation positions.

Here, the indoor ice link is divided into an ice hockey link, a curling competition link, a speed skating link, and a public link. The size of the indoor ice link is determined according to the sports type of the indoor ice link, and another classification is performed according to the link bottom structure of the indoor ice link.

In general, the classification according to the floor of the ice link is as follows.

The floor structure of the ice link can be divided into fixed type and movable type. The movable type is a floor structure which can be moved and assembled when prompt installation and demolition are required, such as when an ice show is performed on the stage. Not to mention the floor structure,

In other words, the fixed floor structure can be classified into a permanent type, an open type, a sand filled type, and an iron plate type bottom structure, and the main points of this method are as follows.

The permanent-type floor is a floor in which the cooling pipe is embedded in the bottom concrete and the floor surface is cleanly finished to utilize the bottom surface as a multi-purpose. Generally, it is used as a gym for other purposes in the summer when power consumption is high. The bottom is horizontal and horizontal, and has a strong resistance to concentrated load. However, cracks may occur due to repeated ice freezing and melting.

In order to prevent cracks caused by shrinkage of the bottom concrete, it is desirable to install joints around the links and to use fillers or the like.

In addition, the open floor or sand filled floor is exposed to the bottom of the cooling pipe and filled with sand. It is not used for other purposes except for skating. It is used for the purpose of lowering the construction cost, It is used when it is necessary to remove the cooling pipe.

Such an open floor or sand filled floor is disadvantageous in that it is easy to install, the equipment cost is low and the cooling pipe is easily demolished and installed, but it takes time to form the ice surface and it is difficult to maintain the level.

In addition, if the steel plate type floor is to be installed on the bottom surface of the cooling pipe, the steel plate finishing method is to be used for a short time, the link and the pool are used together, and the outdoor ice- .

Steel panels, steel bars, steel pipes, etc. are installed on the bottom of the steel plate, and the brine is circulated in the steel plate to form a glazing surface, so that the thermal conductivity is good and the power cost can be reduced and the ice quality is clean and thin.

However, in the fixed floor structure according to the related art, the cooling pipe is embedded in the concrete, which makes it difficult to repair, cracking due to self-expansion and contraction of the bottom wall, and high initial investment cost.

Further, since the cooling pipe is exposed, there is a risk of damage, and it takes a long time to form the ice surface and it is difficult to maintain the horizontal position of ice sheets.

In addition, since the fixed floor structure as described above is formed by the indirect ice making method in which the low temperature brine heat exchanged with the refrigerant in the evaporator of the freezer is sent to the cooling pipe made of the iron material piped to the bottom of the link, The efficiency is low, and the power ratio is large due to the operation of the brine pump. There is a problem that the freezing time is long.

In addition, although the movable ice link has advantages in that it can be easily installed and demounted as compared with the fixed floor structure, there is also a problem that the lamination structure of the insulating layer for minimizing heat loss is also complicated and reuse of the insulating materials in various layers is impossible.

That is, the insulating layer of the movable ice link has a problem in that it can not be reused at the time of dismantling because a plurality of sand, asphalt and wood are stacked and applied so as to have a function of heat insulation, waterproofing and planarization.

In addition, since the plastic cooling pipe applied to the movable floor structure is generally installed by the boiler piping type, the step of installing the plastic cooling pipe in a circulating manner is somewhat complicated, and due to the characteristics of the material of the plastic cooling pipe, If the connection state of the connection part is not certain, leakage of the brine may occur, which may result in deterioration in maintenance efficiency of the ice link.
