摘　　要：以某银行数据中心为研究对象,总结并比较了数据中心常用气流组织形式和制冷方案,计算分析了该数据中心空调冷负荷及常用制冷方案的全年不同运行模式的时长。根据计算、分析结果确定了采用地板下送风+封闭冷通道的气流组织形式和带自然冷却的干式水冷直膨机组的制冷方案,与采用传统风冷空调相比每年预计可节省41.9%的电耗。Taking a data center of a bank as the research object,this paper summarizes and compares the common air distribution forms and refrigeration schemes of the data center,and calculates and analyzes the cooling load of the air conditioning and the uration of different operation modes of the common refrigeration schemes of the data center in the whole year.According to the results of calculation and analysis,the air distribution form of underfloor air supply and closed cold channel and the refrigeration scheme of dry water-cooled direct expansion unit with natural cooling are determined,Compared with the traditional air-cooled air conditioning,it is estimated to save 41.9%of the annual power consumption.
