寒冷地区微模块数据中心能耗分析

从降低数据中心的能耗出发,对工作在自然冷源场景下的冷水机组能耗进行分析,并计算出全年的PUE值。提出了在寒冷地区新建数据中心,采用以微模块为核心,配合具有Free Cooling冷却技术的冷水机组为数据中心进行制冷的技术架构,根据系统仿真测试,结果表明,提高末端空调的供水温度,每当提高1℃的出水温度,冷水机组的制冷量将提高3%~4%,而功耗约增加1%。有效地降低了PUE值,从而节约了电能,降低了碳排量及成本。

Analysis of Energy Consumption by Micro Module Data Center in Cold Regions

Starting from the target of reducing energy consumption in the data center,this paper analyzes energy consumption of the water chiller unit working in the natural cold scenario and calculates the PUE value throughout the year.Researchers suggest selecting the micro module as the core technical framework,and using the water chiller unit with the Free Cooling technology for refrigeration for the data center constructed in cold areas.Simulation shows that an increase of the output water by 1℃ will increase the refrigerating output of the chiller unit by 3%~4% and power consumption by 1%,thus saving electric energy,decreasing carbon emission and reducing cost.
