        摘要:

        综述了国内外吸油烟机捕集性能相关研究,分析了我国及欧美吸油烟机标准中常态气味降低度对真实捕集性能描述存在的问题。构建了吸油烟机捕集率测试新方法:通过设定可控的特征污染稳定散发,以监测相对稳定的排风浓度和厨房空间特征污染浓度,计算出吸油烟机的污染捕集率;建立实验台,利用该新方法实验研究了吸油烟机结构、排风量、热源强度及散发位置对捕集率的影响。对2种新型吸油烟机的多因素对比实验结果表明:捕集率测试方法稳定性好;在低风量范围内(排风量低于600 m3/h),排风量引起的捕集率差异高达20.6%,排风量达到600 m3/h后捕集率无显著变化。2种新型吸油烟机结构差异引起的捕集率差异达到7.3%;实验范围内热源强度变化引起的吸油烟机捕集率差异较小,仅为4.0%;散发位置不同所引起的捕集率差异为15.1%。

        Abstract:

        Summarizes the related research on the capture performance of range hood at home and abroad, and analyses the problems existing in the description of real capture performance by the degree of normal odor reduction factors in the standard of range hood in China, Europe and the United States. Constructs a new method for measuring the capture efficiency of household range hoods. By setting controllable characteristic pollution and stable emission, monitors the relatively stable exhaust concentration and pollutant concentration in the kitchen space, and calculates the pollution capture efficiency of range hoods. Sets up an experimental platform, and studies the effects of range hood structure, exhaust air rate, heat source intensity and emission position on the capture efficiency by this new method. The multi-factor comparative experimental results of two new types of range hood show that the capture efficiency test method has good stability. In the range of low air rate (exhaust air rate is less than 600 m3/h), the difference of capture efficiency caused by exhaust air rate is as high as 20.6%, and there is no significant change when exhaust air rate reaches 600 m3/h. The difference of capture efficiency caused by the structure difference of the two new types is 7.3%, and that caused by the change of heat source intensity is only 4.0%. The difference of capture efficiency caused by different emission position is 15.1%.
