AIR AND AEROSOL INFILTRATION IN HOMES.

Author(s) : MCMURRY P. H.

Summary

THIS PAPER DISCUSSES THE MEASUREMENT OF AIR INFILTRATION RATES AND MEASUREMENTS RELATING INDOOR AND OUTDOOR AEROSOL SIZE DISTRIBUTIONS IN THE 0.01 TO 1 MICROMETRE SIZE RANGE. SIMULTANEOUS MEASUREMENTS OF AIR EXCHANGE RATES WITH THE INDUCED PRESSURE AND TRACER GAS TECHNIQUES WERE DONE IN TWO HOMES, AND THE TWO METHODS WERE FOUND TO AGREE TO WITHIN ESTIMATED EXPERIMENTAL UNCERTAINTIES. INDOOR AND OUTDOOR AEROSOL SIZE DISTRIBUTIONS WERE MEASURED AND COMPARED IN ONE HOME. IT WAS FOUND THAT FOR PARTICLES IN THE 0.01 TO 1.0 MICROM RANGE, THE RATIO OF INDOOR TO OUTDOOR CONCENTRATIONS WAS TYPICALLY BETWEEN 0.2 AND 0.4 AND DID NOT VARY SYSTEMATICALLY WITH PARTICLE SIZE.
