北京地标建筑地下数据中心循环冷却水系统的节能设计

Energy-Saving Design of Circulating Cooling Water System for the Underground Data Center of Beijing Landmark Building

近年来,随着大型数据中心建设规模、数量和电力需求不断增长,节能减排、绿色数据中心成为热门话题;特别是在空调制冷系统建设中,各种节能技术和设备开始普遍应用,但效果并不理想,投资回收期长,运行和维护的成本增加等。针对此问题,论文通过北京某大型数据中心的循环冷却水系统设计实例,介绍了制冷系统方案设计中应考虑的因素,以及应注意的关键点等,希望对同行的设计、建设和运维有所帮助。

In recent years,with the scale,quantity and power of large data center construction,energy saving and emission reduction,green data centers become the hot topic.Especially in the construction of air-conditioning and refrigeration systems,various energy-saving technologies and equipment have begun to be widely applied.However it also has some disadvantages of unsatisfactory results,long payback period,and increased operating and maintenance costs,etc.To solve this problem,this paper introduces in detail the factors and key points in the design of the refrigeration system through the design example of circulating cooling water system in a large data center in Beijing.It is hoped that the design,construction and operation can be useful for the peers.
