摘　　要：数据中心能耗中约35%以上源于全年不间断供冷,节能优化潜力巨大。以某大型数据中心实际工程为基础,从理论上分别对蒸汽压缩式、直燃型和蒸汽型溴化锂吸收式3种制冷方案进行技术经济性对比;再结合蒸汽型吸收式制冷可利用“余热和废热等低品位热能”的特点,针对主用燃气三联供系统在数据中心的应用进行探究,力求从供冷的源头着手寻求节能突破,以期为实际制冷方案的选择提供技术参考。More than 35%of the energy consumption of the data center comes from the uninterrupted cooling throughout the year,which has great potential for energy saving optimization.Based on the actual project of a large-scale data center,this paper theoretically compares the technical and economic efficiency of three refrigeration schemes:vapor compression,direct combustion and vapor lithium bromide absorption.Combined with the characteristics of“low-grade heat such as waste heat and waste heat”that can be used in steam absorption refrigeration,the paper explores the application of the CCHP in data center,in order to provide technical reference for the selection of the actual refrigeration scheme.
