为降低数据中心运行能耗,越来越多的大型数据中心制冷系统采用自由冷却技术,自由冷却系统虽然节能优势明显,但是系统相对复杂,适当的操作以及运行中积累的经验,可更深层次的挖掘系统节能潜力。某东北大型企业数据中心在选址建设时,就本着充分利用东北冬季与过度季节气温较低的优势,采用自由冷却的方式来制取机房空调所需的低温冷却介质-冷冻水。自该中心建成投用以来,通过实际操作摸索,总结出可对自由冷却技术进行攻关调优,通过延长过度季节
In order to reduce the energy consumption of the data center, more and more large-scale data center refrigeration systems adopt free cooling technology. Although the free cooling system has obvious energy-saving advantages, the system is relatively complex, proper operation and accumulated experience in operation can be deeper Digging system energy saving potential. When building a site for a large-scale enterprise data center in northeast China, the low-temperature cooling medium required for room air-conditioners, such as chilled water, is prepared by means of free cooling, taking full advantage of the relatively low winter and over-season temperatures in northeast China. Since the center was completed and put into use, through practical exploration, summed up the free cooling technology can be tackled tuning, by extending the excessive season
