Research on energy-saving optimization of water-cooled refrigeration systems in data centers
YU Shenghui
Abstract：Aiming at the problem of high energy consumption proportion of the cooling system in traditional data centers,taking the cooling system of a certain financial data center as the research object,energy-saving optimization is carried out on the cold source system,the air conditioning system of the computer room,the natural cooling mode and the air flow organization of the computer room by system and stage.The results show that after optimization,the average annual power utilization efficiency(PUE)dropped from 3.46 to 1.38,the energy consumption proportion of the cold source system decreased by 22.75%,the energy consumption of precision air conditioners decreased by 65%,and the natural cooling duration is extended by 33 d.The energy-saving path can decrease operating costs,enhance system reliability,and provide a reference for energy efficiency optimization and green low-carbon development throughout the entire life cycle of data centers.
