摘要(Abstract)：

为了降低数据中心空调系统的能耗，利用间接蒸发冷却性能测试平台，对数据中心用间接蒸发冷却空调机组在干工况、湿工况和混合工况3种不同工况下的性能进行测试及分析。研究结果表明：测试期间机组在干工况下运行时，平均冷却效率为60.2%，一次空气温降平均可达13.0 ℃；湿工况下运行时，二次空气经过湿膜等焓加湿冷却后温降平均可达1.9 ℃，平均冷却效率为60.5%，一次空气温降平均可达12.7 ℃；混合工况下运行时，此时压缩机开启，一次空气温降平均可达12.7 ℃，机组平均COP为3.8。同时通过计算间接蒸发冷却空调机组节电模式、节水模式的切换条件，就典型城市的全年运行小时数进行了分析，通过分析得到数据中心用间接蒸发冷却空调机组应因地制宜地选择运行模式以此降低数据中心空调系统能耗。
In order to reduce the energy consumption of the air conditioning system in the data center，the indirect evaporative cooling performance test platform was used to test and analyze the performance of the indirect evaporative cooling air conditioning unit in the data center under three different working conditions：dry condition，wet condition and mixed condition.The results show that：during the test period，the average cooling efficiency of the units operating under dry conditions is 60.2%，and the average primary air temperature drop is up to 13.0 ℃.The average temperature drop of the units operating under wet condition after the secondary air undergoes wet film isoentropic humidification and cooling can reach 1.9 ℃，the average cooling efficiency is 60.5%，and the average primary air temperature drop can reach 12.7 ℃；the average primary air temperature drop can reach 12.7 ℃ under mixed condition when the compressor is turned on and the average COP of the unit is 3.8.The switchover conditions of the indirect evaporative cooling air conditioning unit in power saving mode and water saving mode were calculated，and the annual operating hours of a typical city were analyzed，through which it is concluded that the indirect evaporative cooling air conditioning unit for data center should choose the operating mode according to the local conditions to reduce the energy consumption of the data center air conditioning system.
