Abstract

With the rapid development of data centres worldwide and keeping climate change in mind, more people are looking at “green data centres”. There is a significant need to cut power consumption as much as possible to become such. Because the cooling system’s power consumption almost matches the power consumption of IT equipment, it vastly increases the PUE coefficient, meaning low energy efficiency of data centres. High levels of bypass airflow and recirculation of air in the server room are the main factors causing a considerable drop in the energy efficiency of data centres. However, the main areas of poor cooling should be identified before performance improvement actions can be taken in existing data centres. This paper addresses the most-known issues impacting the cooling system’s energy efficiency and proposes a possible solution to improve it.
识别无效的冷却措施以提高现有数据中心的能源效率
随着全球数据中心的快速发展和对气候变化的关注,越来越多的人开始关注“绿色数据中心”。要实现这一目标,就需要尽可能地减少电力消耗。由于冷却系统的功耗几乎与IT设备的功耗相当,因此大大增加了PUE系数,这意味着数据中心的能源效率较低。服务器机房的高水平旁路气流和空气再循环是导致数据中心能源效率大幅下降的主要因素。但是,在现有数据中心采取性能改进行动之前,应该确定冷却不良的主要领域。本文解决了影响冷却系统能源效率的最常见问题,并提出了一种可能的解决方案。
