中小型数据中心冷却系统节能诊断与改造方案
Diagnosis and Renovation on Cooling System for Energy Saving in Small and Medium-sized Data Centers
【摘要】 本文重点针对中小型存量数据中心的高能耗问题，进行调研和分析，首先进行能耗问题诊断，造成高能耗的主要因素为冷却系统架构、湿度控制、低外温下设计和运行、自然冷能利用以及长期运行性能衰减；其次从压缩机和换热器等核心部件，并从室内末端、冷水机组系统、直膨系统、输配系统等系统架构方面探讨系统能效提升方案，然后从湿度控制技术、自然冷却技术、蒸发冷却技术、智能控制技术等方面探讨了节能改造技术方案，为存量数据中心节能改造提供参考。
【Abstract】 The high energy consumption of small and medium-sized inventory data centers is focused in this paper.With survey and analysis for energy-saving diagnosis, it’s the main aspects of the cooling system architecture,humidity control, design and operation under low ambient temperature, free cooling, performance decrease for long term operation. Then the performance improvement is discussed from the main components such as compressor and heat exchanger, and the cooling system architecture such as the indoor terminals, water-cooled chiller system, directexpansion refrigeration system, distribution system. At last, the energy-saving transformation technology schemes are proposed as the humidity control, free cooling, evaporative cooling, intelligent control. The above provides reference for energy-saving transformation of inventory data centers.
