Description
The multiple tracer gas method is often used to predict interzonal airflows in buildings.In this study, this method was applied to an isolated space consisting of two interconnected rooms where the airflows through the common wall were controlled and measured. The results indicated that the calculated airflows based on different sets of simultaneously measured tracer gas concentrations (obtained at different sampling times during a test) were not always the same. To improve the accuracy of calculated results, a method was developed to facilitate the selection of appropriate sets of tracer gas concentrations (from the measurements) for use with the multiple tracer gas method. The proposed method was tested in the laboratory. The results are discussed.
KEYWORDS: zones, air flow, tracers, measuring, rooms, walls, calculating.
