Indoor Air Quality Modeling: Phase II Report.


Determination of ventilation efficiency based upon short term tests.

In this paper a short term testing methodology is developed to evaluate the performance of ventilation systems with respect to control of indoor air pollutants. Two efficiency measures, displacement efficiency and removal efficiency, are defined based upon analysis of mass transport into and out of a specified control volume. These new efficiency measures are applied to the analysis of a ceiling based ventilation system and comparisons are made with age of air and pollutant removal effectiveness concepts.
