摘　　要：空调末端风机能耗约占空调运行能耗的30%,如果将该风机更换为运行效率更高的EC风机,节能量将会非常可观。以实际改造项目为例,介绍EC风机的优点,通过选型确定风机的型号,通过经济分析得出EC风机的节能率、节约的电费及投资回报期,进而证明EC风机应用在改造中节能效果明显。The energy consumption of air conditioning fan accounts for about 30%of air conditioning operation.The energy saving will be considerable if the fan is replaced by a more efficient EC fan.The article takes the actual project as an example,introduces the advantage of EC fan,determines the type of fan through selection,obtain the energy saving rate,electricity cost saving and investment return period through economic analysis.It is proved that the EC fan has obvious energy-saving effect in the renovation.

关 键 词：节能改造 EC风机 经济分析 节能
