摘要:

PUE 值是衡量数据中心能源使用效率的关键指标。分析对比了两个数据中心案例的制冷效率、输冷效率、电能转换效率以及输能效率,找出了两个数据中心PUE差异的原因。研究了数据中心节能运行的策略,提出了控制制冷主机运行台数、降低冷却塔出水温度和提升冷冻水水温的 3 项措施。最后提出了在建设和运营数据中心时对于节能方面的建议。

关键词: PUE, 能效, 基础设施, 节能策略

Abstract:

PUE value is the key indicator of energy efficiency in data center.Through the comparative analysis of refrigeration efficiency,cooling efficiency,energy conversion efficiency and energy transmission efficiency,the reasons for difference in PUE between two data center cases were found.Three measures on the strategy of energy-saving operation of data center were put forward,as to control the number of refrigerators,to reduce the temperature of cooling water and to raise the temperature of chilled water.Some inspirations on energy saving in the construction and operation of the data center were raised.

Key words: PUE, energy efficiency, infrastructure, energy saving strategy
