This report describes the initial phase of an effort to
evaluate the ability of multizone airflow and pollutant
transport models to predict the impact of residential
IAQ control technologies. Measurements of the
performance of several particulate air cleaning devices
and related particle transport parameters were performed
in a one-room test house. These measurements were used
to calculate building air change rates, particle
deposition rates and penetration factors, and air
cleaner removal efficiencies. Two separate 24 h tests
were performed with two of the tested air cleaners, and
the measured air change rates and particle
concentrations were compared to predicted values
obtained with the CONTAM model. For both tests,
simulated 24 h average air change rates were within 5%
of measured air change rates and simulated 24 h average
particle concentrations were within 30% of measurements
for all particle sizes. Simulations were also performed
to predict the impact of the air cleaners compared to a
typical furnace filter.
