摘　　要：本文以某数据中心机房为例,通过改造原有空调系统以充分利用全年室外空气冷源,利用单向二极管式热管构建热管/蒸汽压缩复合空调系统,以固化十二醇硬脂酸为蓄冷材料增设蓄冷系统,结果显示:改造后能源使用效率PUE从2.1降低为1.51,自然冷却全年使用时间占75%,年节能率达28%。并提出了自然冷却能效FCE,探讨了北方地区数据机房利用自然冷源的途径,对数据中心的节能设计具有参考价值。Take a data center room in a university as an example,one-way diode heat pipe was used to build a heat pipe/vapor compression air conditioning system,and add an additional cool storage system with PCM material of solidification dodecanol-stearic acid,in order to take full advantage of year-round outdoor cold air.Results shows that after the renovation the PUE descended from the original 2.1to 1.51,the time span of heat pipe annually occupies 75 percent,and annual energy saving rate reaches 28%.An index FCE was also proposed to measure the overall efficiency of the free cooling use.The utilization of natural cooling source in the northern regions for data center has been explored,and the essay has provided a valuable reference for energy-saving design of the data centers.
