Water-side economizer (WSE) systems are being introduced to reduce cooling energy in data centers, but quantitative comparisons of various controls are impossible as the configurations of the systems are different. Therefore, this study reviewed the energy consumption according to the free cooling operation mode of the WSE system, and analyzed the operation status according to the South Korea climate zone to reduce additional energy and secure free cooling operation time. In the case of a WSE system that can only operate full-free cooling, about 10.9% of energy was saved. When full and partial-free cooling operations were implemented through th serial connection between the chiller and the heat exchanger, 13.7% of energy was saved. In particular, Daegwallyeong (6A), located in the climate zone with the lowest ambient air humidity temperature, Showed the highest energy savings of about 19.5% compared to the center chilled water system as free cooling operating time was secured the most. |
