摘　　要：针对数据中心空调系统全年不间断供冷、运行能耗高的特点,提出一种由蒸发冷却冷水机组作为全年主导冷源,并结合乙二醇自由冷技术的数据中心用新型蒸发冷却空调系统,充分利用室外环境干空气能与冬季自然冷源,实现干燥地区数据中心全年完全自然冷却。本研究的目的在于,介绍新系统的工作原理,分析系统运行中蒸发冷却冷水机组运行参数以及新型蒸发冷却空调输配系统在数据中心运行过程中参数变化规律,并讨论其节能性,为数据中心冷却工作提供新思路。以新系统实际应用工程——乌鲁木齐某数据中心(冷负荷为2760kW)为研究对象,选取最热月的典型日,通过对系统进行逐时运行参数的实际测试,得出空调系统各换热环节热量传递过程的温度、热量变化规律。在乌鲁木齐夏季最热时,蒸发冷却冷水机组全天出水温度范围在13.1~16.9℃,平均值为14.9℃,新型蒸发冷却空调系统COP值为6.65kW/kW,相比传统机房制冷系统节能率超过60%。For data center for uninterrupted cooling air conditioning system,the characteristics of high energy consumption of the operation,put forward a kind of the evaporative cooling water chillers as cold source and throughout the year and combined with ethylene glycol free cold technology data center for new evaporative cooling air conditioning system,can make full use of the dry air outdoor environment and natural cold source in winter,dry areas data center for natural cooling completely.The purpose of this study is to introduce the working principle of the new system,analyze the operating parameters of the evaporative cooling chiller in the system operation and the variation rules of the parameters in the data center operation of the new evaporative cooling air conditioning transmission and distribution system,and discuss its energy conservation,so as to provide a new idea for the data center cooling work.Taking a data center in urumqi,a practical application project of the new system(the cooling load is 2760kW),as the research object,the typical day of the hottest month is selected,and the temperature and heat change rules of heat transfer in each heat exchange link of the air-conditioning system are obtained through the practical test of the system's time-by time running parameters.In the hottest summer in urumqi,the all-day water outlet temperature of the evaporative cooling chiller ranges from 13.1℃to 16.9℃,with an average value of 14.9℃.The COP value of the new evaporative cooling air-conditioning system is 6.65kW/kW,and the energy saving rate is more than 60%compared with the traditional machine room cooling system.
