Description

The multiple tracer gas method is often used to predict interzonal airflows in buildings. In a previous study, this method was applied to a space consisting of two interconnected rooms where the airflows through the common wall were controlled and measured. The results indicated that the predicted airflows based on different sets of simultaneously measured tracer gas concentrations (obtained at different sampling times during a test) were not always the same. Guidelines are, therefore, needed to facilitate the selection of the appropriate set of tracer gas concentrations (from the measurements) for use with the multiple tracer gas method. In this study, the test rooms were expanded to three interconnected rooms. A method was developed to determine the appropriate set of concentrations for interzonal airflow calculations. The proposed method was tested in the laboratory and the results are discussed.

KEYWORDS: zones, air flow, tracers, measuring, rooms, walls.
