The manufacturing procedures and performance of a building air infiltration kit consisting of miniature passive perfluorocarbon tracer permeation sources and passive adsorption tube samplers are described.
The Brookhaven air infiltration measurement system (BNL/AIMS) uses a family of four passive perfluorocarbon tracer sources and miniature passive adsorbent samplers to inexpensively but very effectively tag individual zones within multizone buildings with uniquely discernible tracer vapors.
Three different types of methods for estimating ventilation rates in residences have been presented and the results of each method discussed. Field measurement experiences have helped to identify the potential errors of these methods. To date, the best correlations obtained have been between theconstant emission tracer methods involving perfluorocarbon and tracer gases. It is expected that a better understanding of the parameters that affect all of the techniques, specifically mixing volume, will lead to improved accuracy.
Continuous monitoring of NO, NO2, CO, CO2, and O2 depletion was conducted in 14 residences (13 with kerosene space heaters and one without) in two locations in the residence (room with the heater and bedroom) and outdoors. The continuous monitor
Using miniature perfluorocarbon tracer (PFT) sources and miniature passive samplers, tests conducted in the lab and in a typical home successfully demonstrate the utility of the PFT kit as a means for implementing wide-scale infiltration meas
