Purpose: In most domestic data centers, a perforated panel or a grating panel is equally placed on the entire top surface at the same rate for cooling the server room. However, in such a supply system, there is a situation where cold air can not be supplied uniformly according to the supply distance due to the air velocity discharged from a CRAC (computer room air conditioning) unit. However, considering the cost and difficulty of repairing the existing system, it is practically the most effective way to raise the air-conditioning efficiency index by adjusting the aperture ratio of the perforated plate to form an even airflow distribution. Method: The cooperative effect of the uptake system using the perforated plate was analyzed for the bottom extraction method, and the feasibility of the improvement was analyzed through CFD analysis. Result: As a result of CFD simulations, the RCIHI increased from 86.1% to 89.2% and the RCILO increased from 90.3% to 91.2% by 0.9%. Although it is possible to confirm the possibility of improving the efficiency of air conditioning in the simplest of the facilities related to the server room of the data center, the quantitative effect is not so high.
