Résumé

Data centers are growing rapidly, and their power demand is increasing significantly owing to their crucial role in data processing and storage. Recently, the adoption of free cooling methods utilizing economizers has emerged as a strategy to mitigate power consumption for data centers. However, limited research has been conducted on achieving optimal energy efficiency and reducing power consumption for data center operations. Furthermore, owing to the weather-dependent nature of free cooling methods, a regional analysis is essential. The objective of this study is to compare and optimize the free cooling methods utilizing economizers across different regions. TRNSYS was used to model data center systems. Two types of economizers, namely water-side economizer (WSE) and air-side economizer (ASE) systems, were modeled with three weather datasets in Cairo, Seoul, and Toronto. The ASE outperformed the WSE owing to its wider operating temperature range and utilization. In Seoul, when the ASE was applied, the annual PUE decreased from 1.275 to 1.209. Notably, the economizer performance was better in Toronto than in Cairo. When the ASE was applied, the annual power usage effectiveness (PUE) decreased by 0.033, 0.066, and 0.078 in Cairo, Seoul, and Toronto, respectively. This phenomenon was particularly noticeable in regions with cooler climates, where economizers showed enhanced efficiency.
