The present invention relates to a centralized sea water supply and cooling system, and more particularly, to a system and method for providing centralized sea water supply and cooling systems, and more particularly, To a centralized sea water supply and cooling system that can be maintained at a moderate temperature.

In recent years, as the national income has increased, the consumption of live fish animals has increased along with the consumption of meat.

Fish species such as sea bream, halibut, and viscous fish, shellfish such as scallop, shellfish, mackerel, octopus such as octopus and squid, crustaceans such as crab, shrimp, etc. And other aquatic animals) will be stored at high density in water tank facilities adjacent to coastal waters. It also carries out the export and import procedures or distributes the water tank facilities of the consumption areas of the whole country, that is, the water tank facilities where the certain fish animal environment (water temperature) is maintained.

The water tank facility used for high-density storage of living fish animals as described above is usually installed in the land portion of the coastal waters, and the sea water is directly pumped from the watershed connected to the land portion and supplied to the water tank. At this time, the seawater supplied to the water tank is circulated and purified through various filtering devices provided with the water tank, and the natural sea water temperature and the like are maintained, so that the fish animals stored in the water tank can be stored or reared for a predetermined period.

On the other hand, in the mid- to large-sized market where the distribution of fish animals is intensively concentrated, shopping malls are concentrated, and each shopping mall has at least one water tank for sale and storage.

Each shopping mall has a cooling unit for cooling seawater at a predetermined temperature suitable for aquatic animals stored for each tank for water tank management and a filter unit for purifying contaminated seawater so that fish animals can be distributed in the best condition .

However, this structure is not easy to supply seawater to the water tank installed at each shopping mall, and since a cooling device for cooling the water stored in the water tank needs to be installed, the manufacturing cost of the water tank is relatively high. Although the level needs to be upgraded, the management of the water tank is not easy, and it is more difficult to maintain the water tank constantly in accordance with the hygiene level.

The centralized seawater supply and cooling system according to the present invention configured as described above can be used to supply seawater to each of the water tanks 200 installed in the live fish cen- tre center and cool the supplied seawater.

That is, the seawater supply to each water tank 200 is performed by driving the seawater supply pump 22a installed in the seawater supply pipe 22 of the seawater supply unit 20 to supply seawater in the seawater storage tank 21 to the supply pipe 22, (23). In this state, the valve installed in the branch pipe 23 is opened and closed to supply the selected water tank 200, that is, the water tank 200 requiring the supply of the seawater. The amount of seawater supplied to the water tank 200 is metered by the meter 24, and the seawater usage cost can be collected on a monthly basis. The seawater temperature in the seawater storage tank 21 supplied by the seawater supply unit 20 can be maintained at a predetermined temperature (desired temperature).

As described above, when the supply of the seawater to the water tank 200 is completed, the live fish and shellfish are stored in the water tank 200. Even during storage of the live fish and shellfish, the supply of the seawater can be continuously performed as described above.

The sea water supplied to the water tank 200 can be adjusted by the water tank temperature control unit 50 as described above. First, in order to lower the temperature of seawater in the water tank 200, the heat exchange medium in the heat exchange medium storage tank 51 is first cooled.

The cooling of the heat exchange medium stored in the heat exchange medium storage tank 51 is performed by circulating the heat exchange medium in the heat exchange medium storage tank 51 to the second heat exchanger 71 installed in the refrigeration or freezing warehouse 500, As shown in FIG. The third circulation pump 73 provided in the second circulation pipe 72 connecting the second heat exchanger 71 and the heat exchange medium storage tank 51 is operated to circulate the heat exchange medium. Cooling of the heat exchange medium in the heat exchange medium storage tank 51 may be performed by the second cooling unit 70 or may be performed in parallel with the second heat exchanger.

The second pump 53 is driven while the heat exchange medium of the heat exchange medium storage tank 51 is cooled to cool the water tank 200 through the supply pipe 51 and the unit supply pipe 81, And then returned to the heat exchange medium storage tank 51 through the unit return pipe 82 and the return pipe 52 after the heat exchange with the seawater of the water tank 200 described later is performed.

Here, the heat exchange medium includes a second heat exchanger 71, an auxiliary supply pipe 75, a supply pipe 51, a unit supply pipe 81, a unit heat exchanger 83, a unit return pipe 82, , The return pipe (52), and the second circulation pipe (72).

The unit heat exchanger 83 composed of the dual heat exchanger drives the unit pump 87 installed in the unit inlet pipe 85 for introducing the seawater to circulate the seawater of the water tub 200. The sea water in the water tank 200 is circulated to the unit heat exchanger 83 through the unit inlet pipe 85 and the unit outlet pipe 86 to be heat-exchanged with the heat exchange medium.

In this process, microbubbles, that is, small air bubbles, can be piled on the seawater to increase the amount of dissolved oxygen in the seawater. That is, when the valve 102 of the bubble generating air inflow pipe 101 installed in the unit inflow pipe 85 on the suction side of the unit pump 87 is opened or closed, part of the air is introduced into the pump by the suction force of the pump. The introduced air is pulverized in the pump housing by the impeller of the unit pump 87 and piled on the seawater circulated with very small air bubbles. Therefore, a large amount of air bubbles can be supplied to the interior of the seawater, thereby increasing the amount of dissolved oxygen. The bubbling air inflow pipe 101 may be supplied with oxygen.

A filter is installed on the suction side of the unit inflow pipe 85 and the foam diffusion preventing unit 90 is installed on the end of the unit discharge pipe 86 so that pollutants piled up in the seawater can be filtered, It is possible to prevent the diffusion of bubbles generated by circulation of seawater and increase the amount of dissolved oxygen.

Is sprayed to the impact plate member 95 and the mixing plate 97 through the injection hole 94 of the spray pipe 93 provided inside the housing of the foam diffusion prevention unit 90 through the unit discharge pipe. The bubbles generated during the supply of the seawater can not be diffused from the inside of the housing member 91 to the outside of the housing member 91, And disappears inside the member (91).

As described above, the centralized seawater supply and cooling system according to the present invention can freely supply the seawater to each water tank 200, and can adjust the seawater temperature in the water tank arbitrarily. Therefore, And the cost of seawater can be reduced because the sea water is supplied from the center.

In addition, since the supply of seawater or the bubbles generated from the oxygen generator can be prevented from floating on the sea water surface in the water tank 200, the quality of the seawater can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
