基于自然水源的数据中心能源梯级利用研究OA

An energy cascade utilization scheme for data centers that combines liquid cooling technology and natural water sources is proposed in this paper.Taking a data center in Laibin City,Guangxi as an example,its waste heat recovery and energy consumption are analyzed,and they are compared with those of conventional systems.The results show that the proportion of natural cooling time in this scheme exceeds 60%.The direct use of waste heat for fish farming has low costs and high benefits.Compared with the fully mechanical refrigeration system,the cooling efficiency ratio is increased,thepartial power usage effectiveness is decreased,the annual power savings is reached 4 602 491 kW·h,and the CO₂ emissions are reduced by 2 563 tons.Compared with the air-cooled terminal system,the annual power savings are 12 890 540 kW·h,and the CO₂ emissions are reduced by 7 177 tons.Although the initial investment is high,the annual power cost savings are considerable,achieving a good balance in energy conservation,environmental protection,and economic benefits,and having the potential for promotion in suitable areas.
