摘　　要： 论文介绍了某高性能数据中心空调系统采用闭式冷却塔+水冷磁悬浮冷水机组的设计方案以及节能运行模式,并给出了运行模式间转换温度的确定方法。研究表明:采用此方案后,可充分利用自然冷源,减少压缩机运行时间,节省能耗。与传统风冷直膨式空调能耗对比,年节省能耗达46.9%。 This paper introduces the design scheme and energy saving operation mode of the closed cooling tower and magnetic levitation chiller used for air conditioning system in a high performance data centers,the method of determining the switching temperature between operating modes is given.The research results show that the scheme can make full use of natural cold source,reduce the running time of the compressor and save the energy consumption.Compared with energy consumption of the traditional air cooling direct expansion air conditioning,it saves energy consumption up to 46.9%.
