Experimental method for contaminant dispersal characterization in large industrial buildings ...

Summary

States that spatial contaminant distribution in semi-open building areas such a sports arenas, warehouses, atriums, malls and other industrial halls, is critical to estimating exposure, health risks and building energy performance. Notes it is considered a challenge to measure experimentally how effectively the ventilation system removes or dilutes air pollutants in a large open space, taking into consideration the usual non-uniformity of the air flow created, local heat and contamination sources, geometrical obstructions and the air distribution system. Presents an experimental method which can be used for both the experimental evaluation of ventilation effectiveness as well as for CFD modelling validation in large open space applications. The developed method, which is based on a passive perfluorocarbon tracer gas system has been used successfully for the experimental evaluation of ventilation effectiveness in an ice skating arena in the Boston area and for the validation of a developed CFD model for the analysis of the IAQ in ice rink facilities. States the method is very easy to use, fast and fairly inexpensive and it does not interfere with human and other activities within the building environment.
