Abstract: Range hood is an important equipment to control kitchen contaminant, capture performance is a significant index to evaluate range hood, which has been widely recognized at home and abroad. Summarizes the typical parameters and test methods of the range hood's capture performance, and analyzes the influence of the mounting height, air supplement mode and heat source characteristics on the capture performance. The results show that in a certain extent, reducing the mounting height and heat source intensity, increasing the air volume and pressure, using the back heat source and taking appropriate air supplement can effectively improve the capture performance of the range hood. However, beyond this extent, the change of the capture performance is small, and the energy consumption and noise will be increased.

Key words: Range hood, Capture efficiency, Tracer gas, Airflow rates, Influencing factors
