At this time, the foreign substances included in the outside air can be cut off through the outside air inlet 110 and the filter unit 120. [ The air outside the room is cooled or humidified by the mist sprayed from the mist sprayer 130 while passing through the mist sprayer 130 of the server room cooling apparatus 100. The cooled or humidified ambient air is then supplied to the server room 200 through the first supply unit 150 and / or the second supply unit 160 provided at one side of the server room cooling apparatus 100. At this time, the server room cooling apparatus 100 operates the cooling member 141 provided in the cooling unit 140 of the server room cooling apparatus 100 when the temperature of the outside air is higher than a predetermined value, So that cooler air can be supplied.

The cold air supplied to the cool zone CZ of the server room 200 flows into the server rack 210 provided in the server room 200 and is supplied to the server rack 200 by a plurality of servers included in the server rack 200 And is discharged to the hot zone HZ after being heated and exhausted to the outside of the server room 200 through the exhaust unit 220 provided on the upper side of the hot zone HZ. At this time, a part of the air discharged to the exhaust part 220 may be supplied to the outside air inlet part 110 through the return duct part 170 of the server room cooling device 100, if necessary.

According to the present invention, it is possible to efficiently utilize the space by reducing the number of equipments provided in the air conditioning system of the data center. Further, by optimizing the interval between the mist spraying section 130 and the cooling section 140, an effect of improving the cooling efficiency by the mist spraying can be obtained. In addition, it is possible to obtain an effect of minimizing the bending of the outside air flow path, securing a natural air flow space, and reducing the power for flowing the outside air. Furthermore, since cooling can be performed only by the secondary side exhaust power without primary side power transmission, it is possible to obtain an effect of further reducing the energy due to an increase in the supply rate of outside air supply in the server room.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the exemplary embodiments, and that various changes and modifications may be made therein without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
