高密度数据中心水蓄冷方案解析

摘要

In this paper, an analysis is made on the necessity of continuous cooling in high density data centers, relevant specifications as well as advantages of chilled water storage.According to different settings of cold sources in a high density data center, multiple optimized configuration solutions for chilled water storage are analyzed, and emphasis is placed on the difference between the open cold storage tank with secondary pumps in parallel and the closed cold storage tank with primary pumps in series.Moreover, the specifications and technical key points with respect to chilled water storage equipment are analyzed accordingly.%分析高密度数据中心连续制冷的必要性、规范要求和水蓄冷的优势.针对高密度数据中心不同的冷源设置形式,解析水蓄冷对应的多种优化配置方案,并重点对比了二级泵并联开式蓄冷罐和一级泵串联闭式蓄冷罐之间的差异,同时对水蓄冷设备的规范要求及技术要点做了相应分析.
