数据中心直接蒸发型风冷机房空调和水冷冷水空调方案的能效分析
Energy efficiency analysis between air cooling direct evaporative air conditioning and water cooling air conditioning solution for data centers
摘要：
针对数据中心常用的直接蒸发型风冷机房空调方案和水冷冷水机组+冷水型机房空调末端方案，通过分析和计算，认为空调方式节能与否与数据中心的容量和地理位置有关，在北方地区，直接蒸发型风冷空调方案有优势；水冷冷水机组+冷水型机房空调末端方案在巨型数据中心（机房面积>8 000 m2）应用有优势，风冷机房空调方案则在大中型数据中心更具有优势。

Abstract：
By analysis and calculation of air cooling direct evaporative air conditioning solution and water cooling units plus terminal coil solution, thinks that the energy saving of air conditioning pattern lies in the air conditioning load and the geographic position of the data center. The air cooling solution has advantage in northern area. The water chilling solution has advantage for the giant data center (area larger than 8 000 m2 ). Air cooling solution has more advantage for large and middle size data centers.
