摘　　要：以数据中心采用的冷却塔间接供冷系统为研究对象,分析了不同工况、不同空调冷水温度时冷却塔、制冷机组及板式换热器的性能变化趋势。并以某数据中心的空调系统为例,建立了分析模型,计算分析了不同冷水温度时,冷源综合制冷性能系数(SCOP)及全年运行能耗情况。结果表明,通过提高空调冷水温度、增加冷却塔的冷却能力,可减少制冷机组的全年运行时间,显著降低全年运行能耗。This paper takes the cooling tower indirect cooling system used in the data center as the research object,and analyzes the performance trend of cooling towers,refrigeration units and plate heat exchangers under different working conditions and different air-conditioning cold water temperatures.Taking the air conditioning system of a data center as an example,an analysis model was established to calculate and analyze the comprehensive coefficient of performance(SCOP)of the cold source and the annual operating energy consumption at different cold water temperatures.The results show that by increasing the temperature of the air-conditioning cold water and increasing the cooling capacity of the cooling tower,the annual operating time of the refrigeration unit can be reduced,and the annual operating energy consumption can be significantly reduced.
