摘　　要：自然冷却技术的合理利用能够大大降低数据中心能耗,然而良好效果的实现需要充分考虑室外气象条件和冷却塔换热能力的变化。对重庆某数据中心的现场实测表明:应用冷却塔对该数据中心进行自然冷却一天可节能7990kWh,节能率为8.05%;该数据中心冷却塔存在冬季供冷能力不足问题,应用完全自然冷却时其最大制冷量仅为额定制冷量的50%左右,需要额外增开系统数量才能保证末端需求;最后从设计和运行两个方面提出了相应的解决方案。The rational use of natural cooling technology can greatly reduce the energy consumption of the data centers,but the realization of good effects needs to fully consider the changes of outdoor meteorological conditions and heat transfer capacity of cooling towers.The field measurement of a data center in Chongqing shows:the application of water-side free cooling can save 7990 kWh a day and the energy saving rate is 8.05%;the cooling capacity of cooling tower is insufficient in winter,and the maximum cooling capacity of the cooling tower is only about 50%of the rated cooling capacity in winter so that it is necessary to increase the number of systems to meet the terminal requirements;Finally,the corresponding solutions are put forward from two aspects of design and operation.
