自然冷却技术在北疆某数据中心的应用 1 广东省电信规划设计院有限公司 吴学渊 许新毅 李依轩 摘要 本项目针对我国西北严寒地区低温少水的气候条件，根据数据中心高热低湿的运行特点，在北 疆地区采用了耗水量少的风冷冷冻水空调系统 （带自然冷源），在过渡季节及冬季采用部分或完全自 然冷却来节省空调运行能耗；为解决水系统在冬季结冰风险及保证空调末端高效换热运行能力，本 方案采用了二级泵系统，冷源侧采用乙二醇水溶液，负荷侧采用清水，两者之间利用板式换热器进 行换热。采用该项技术后，节能率可提高 13%，全年可节约电量约567 万kw ·h ，减少二氧化碳排 放量约 180 万kg 。 关键词：数据中心；自然冷却；水系统防冻；乙二醇系统 Application of natural cooling technology in a data center in the north of Xinjiang Guangdong Telecom Planning and Design Institute Co., Ltd. Wu Xueyuan Xu Xinyi Li Yixuan Abstract This scheme is less water on the low temperature cold regions of Northwest China climate conditions, according to the operating characteristics of the data center of high humidity, in Xinjiang area north of the water consumption of water cooling refrigeration air conditioning system in the transition season and some or all of the natural cooling in winter to save energy; in order to solve the problem in the winter ice water system and air conditioning to keep heat transfer efficient operation mode, this scheme adopts two grade pump system, cold source side by using ethylene glycol aqueous solution, the load side use the water system, the heat exchange between the transfer plate. After the adoption of this technique,energy saving rate can be increased by 13%, energy saving is about 5 million 670 thousand KW. H in the year, Reducing carbon dioxide emissions by about 1 million 800 thousand kg. 1 工程概述 1.1 建筑概况 本工程为北疆某数据中心，建筑地上4 层，建筑高度2 2 2.8m，建筑面积11320 m 。首层为高低 1吴学渊，男，1991 年3 月生，硕士，工程师 510630 广州市天河区中山大道华景路 1 号南方通信大厦广东省电信规划设计院有限公司 联系电话Email: wuxueyuan@ 1 压配电用房、空调换热机房、油机房等配套用房，2 到4 层为数据机房及电力电池用房。
