空气过滤器能效分级适用性探讨
Applicability discussion on energy efficiency classification of air filters
摘要：
根据EN 779标准对16只不同过滤级别的空气过滤器样品进行了性能试验，依据EUROVENT 4/11的能效分级方法对受试空气过滤器进行了能效分级。试验数据分析结果表明，该分级标准对于部分类型（F级）过滤器的平均阻力范围选取过小，不能准确反映过滤器在实际应用过程中的能耗差异。提出应以2倍初阻力作为计算终阻力，同时建议采用单位容尘量平均能耗作为过滤器能效评价标准。
Abstract：
Tests the filtration performance of sixteen air filters with different filtration classification based on EN 779 standard and classifies their energy efficiency classification according to the method stipulated by EUROVENT 4/11 standard. Analysis results of the testing data indicate that the limited range of average pressure drop for fine filters suggested in EUROVENT 4/11 standard could not accurately reflect the actual energy consumption difference of the filters. Suggests that two times initial filter pressure drop should be taken as the finial pressure drop to calculate average pressure drop and energy efficiency classification should be based on average energy consumption per unit dust holding capacity.
Keywords:energy efficiency classification, air filter, applicability, energy efficiency evaluation, average energy consumption per unit dust holding capacity
