The present experimental project is to measure the capture efficiency of domestic range hoods and then to propose optimized designs. New regulations in North America will impose to measure this parameter in a close future as it has been done for labelling purpose in Europe few years ago. This is of prime importance since most of indoor pollutant emissions are due to cooking activities. This will help reducing the pollutant emissions and thus improving human health and air indoor quality. Flow velocity and concentration measurements will be conducted by three measurement techniques. The standard test method developed by ASTM international will be followed. A better insight into the flow dynamics of the plume should be gained enabling to propose alternative scenarios to the existing standards.

本实验项目是测量家用抽油烟机的捕集效率，然后提出优化设计。北美的新法规将在不久的将来强制测量该参数，因为几年前欧洲已为标签目的而进行了测量。这是最重要的，因为大多数室内污染物排放是由于烹饪活动。这将有助于减少污染物排放，从而改善人体健康和室内空气质量。流速和浓度测量将通过三种测量技术进行。将遵循ASTM国际制定的标准测试方法。应该更好地了解羽流的流动动力学，以便能够提出现有标准的替代方案。
