摘　　要：结合北京地区的气候特点,分析了间接蒸发冷却空调在数据中心不同送/回风温度、冷却效率时的切换温度及全年运行时长;通过建立计算模型,计算了对应不同空调送/回风温度、间接冷却效率时的能耗情况,并以某数据中心为例,计算了采用间接蒸发冷却空调和传统空调的初投资、运行费用等;根据计算结果分析,同等冷却效率下,提高空调送回风温度可显著降低全年空调电耗;采用间接蒸发冷却空调比传统空调节省电耗44%。Combined with the climatic characteristics of Beijing, this paper analyzes the switching temperature and annual operating time of indirect evaporative cooling air conditioners in the data center with different supply/return air temperatures,cooling efficiency;By establishing a calculation model, the energy consumption corresponding to different air-conditioning supply/return air temperatures and indirect cooling efficiency was calculated. Taking a data center as an example, the initial investment and operating costs of indirect evaporative cooling air conditioners and traditional air conditioners were calculated;According to the analysis of the calculation results, under the same cooling efficiency, increasing the temperature of the air-conditioning supply and return air can significantly reduce the annual power consumption of the air-conditioning;the use of indirect evaporative cooling air-conditioning saves 45% of the power consumption compared with the traditional air-conditioning.
