Abstract
A modified derivation of capture efficiency of kitchen range hoods in a confined space based on a two-zone non-mixing model is presented. The capture efficiency equals the ratio of capture flow rate to the total plume flow rate at the front canopy height. The new derivation also showed that in order to measure the capture efficiency of a range hood in a confined space, one should measure at least four concentrations of a tracer gas or a pollutant. Our theoretical predictions are compared against a recent experimental study. Suggestions are made on possible improvement of capture efficiency predictions
