The size and number of internet data center (IDC) has been growing rapidly as IT demand has increased recently. IDC needs 10 times as much energy as regular office buildings, there are problems with global warming and increasing carbon emissions. IDC's cooling energy consumption to maintain the IT equipment environment accounts for about 35% of total energy consumption. Therefore, the use of cooling energy was reviewed through simulation by applying the low cooling water temperature system and the free cooling system in this system.
Based on this, cooling performance was analyzed using MLC (Mechanical Load Component) indicators. As a result of the simulation, energy consumption in low cooling water temperatures decreased by 8% compared to normal water-cooling systems, while WSE (Water Side Economizer) and ASE (Air Side Economizer) decreased by 26% and 32%, respectively. Since the MLC of conventional water-cooled system was 0.13 which is lower than Incheon's maximum allowable value of 0.18. As a result of the MLC analysis, it was determined that the cooling system was properly designed. The cooling energy usage showed a significant reduction rate in the order of low cooling water temperature, WSE, and ASE, and the ASE was the most efficient operation with 26.3%. |
