摘要
GB 19761—2020对于通风机能效等级的划分未考虑传动装置和调速装置对能耗的影响,仅根据通风机能效等级无法评判其实际运行是否节能。因此,需要建立一个适合通风机系统能效评价的新方法或采用新的评价指标。本文通过对标准GB/T 15913,GB/T 13466,GB 19761,AMCA205,AMCA207和AMCA208的解读,介绍通风机能效等级(FEG)的优缺点和通风机系统能效评价指标(FEI)的研究现状,为建立完善的通风机系统能效评价指标提供参考。
The impact of transmission and speed control devices on energy consumption when classifying the fan energy efficiency is not considered in GB 19761-2020,thus it can not judge whether the fans actually save energy based on the fan energy efficiency level alone.For this reason,it is necessary to establish a new method or index suitable for energy efficiency evaluation of fan systems.Through the interpretation on GB/T 15913,GB/T 13466,GB 19761,AMCA205,AMCA207 and AMCA208 standards,the advan-tages and disadvantages of the fan efficiency grades(FEG)and the research status of the energy efficiency evaluation index(FEI)of fan system are introduced,which provides suggestions for establishing a perfect energy efficiency evaluation index of fan system in China.
