数据中心局部电能利用效率测算方法与实证研究
Calculation method and empirical research onpartial PUE in data centers
摘要：
针对数据中心不同分区电能利用效率(PUE)的测算需求,确定了分区内能耗构成,包括IT设备能耗、空调末端分摊能耗、冷源系统分摊能耗、供配电系统分摊能耗和其他系统分摊能耗。通过建立5个能耗指标的测算模型,最终形成了数据中心局部电能利用效率(pPUE)的测算方法,并选取了数据中心典型机房开展实证研究,为数据中心能耗指标监测和完善提供参考和依据。
Abstract：
According to the calculation requirements of power usage effectiveness (PUE) in different zones of data centers, the energy consumption composition in the zones is determined, including the energy consumption of IT equipment, air conditioning terminal, cold source system, power supply system and other systems. By establishing the calculation model of 5 energy consumption indicators, the calculation method of partial PUE(pPUE) of data centers is finally formed, and the typical data center room is selected to carry out empirical research, so as to provide reference and basis for the monitoring and improvement of data center energy consumption indicators.
