贵阳某数据中心多种空调形式的应用分析

Application analysis of various air conditioning formsin a data center in Guiyang

以贵阳某数据中心为研究载体,通过对工程概况、气候条件、资源条件、空调原理和技术方案的分析,对比探究了各空调方案的机柜出架数量、节能性和经济指标。结果表明:磁悬浮蒸发相变冷却空调方案建设投资高,但能够大幅度提高机柜出架数量和项目收益;该空调系统全年耗电量较少,但水资源消耗大。间接蒸发冷却空调方案的节能性最优,但是机柜出架数量最少,单位功耗造价高,利润率低。水冷式冷水空调方案节能性差,机柜出架数量较少,但建设投资低。

This paper takes a data center in Guiyang as the research carrier.Through the analysis of the project overview,climate conditions,resource conditions,air conditioning principle and technical scheme,the number of cabinets,energy conservation and economic indicators of each air conditioning scheme are explored and compared.The results show that the construction investment of the maglev evaporative phase change cooling air conditioning scheme is high,but it can greatly improve the number of cabinets and the project income.This air conditioning system consumes less electricity throughout the year,but the water consumption is large.The indirect evaporative cooling air conditioning scheme has the best energy conservation,but the number of cabinets is the least,the unit power consumption cost is high,and the profit rate is low.The water-cooled chilled water air conditioning scheme has poor energy conservation and less number of cabinets,but the construction investment is low.
