摘　　要：为了改善数据中心制冷系统空调能耗大的问题,对现有的间接蒸发冷却空调进行能耗分析。通过焓差实验模拟空调的不同运行模式,测试室外干、湿球温度对空调机组总功率以及能效(coefficient of performance,COP)的影响规律。以乌鲁木齐市(干燥地区)、北京市(中等湿度地区)、广州市(高湿度地区)为代表,通过模拟分析得到该空调机组“干模式+湿模式”年运行时长占比分别为95%、74%、36%;全年累计耗电量分别为296662、357108、490169 kW·h,年累计节电量分别为345738、285292、152231 kW·h,适用性与节电性良好。In order to solve the problem of high energy consumption of air conditioning in data center refrigeration system,the energy consumption of existing indirect evaporative cooling air conditioning was analyzed based on energy saving.The enthalpy difference laboratory was used to simulate different operation modes of air conditioning,and the influence law of outdoor dry and wet bulb temperature on total power and coefficient of performance(COP)of air conditioning unit was tested.Urumqi(dry area),Beijing(medium humidity area)and Guangzhou(high humidity area)were selected to simulate and analyze the annual operating time of“dry mode+wet mode”of the air conditioning unit,accounting for 95%,74%and 36%respectively.At the same time,the annual accumulative power consumption is 296662,357108,490169 kW·h respectively,and the annual accumulative power saving is 345,738,285,292,152231 kW·h respectively,which has good applicability and power saving.
