Abstract:
The impact of central forced-air heating and cooling
system modifications on the levels of selected
pollutants in single-family houses was evaluated by
simulating pollutant concentrations due to a variety of
sources in eight houses with typical HVAC systems.
Simulations were performed with a multizone airflow and
pollutant transport model and were repeated with the
systems modified to include an electrostatic particulate
filter, a heat recovery ventilator, and an outdoor air
intake damper. The system modifications reduced the
pollutant levels in the houses for some cases; however,
the results also demonstrated potential limitations in
both the simulation method and the performance of the
devices.
