Compensating for Wall Effects in IAQ (Indoor Air Quality) Chamber Tests by Mathematical Modeling

摘要

The paper presents mechanistic mathematical models that account for two phenomena: interior surfaces of a state-of-the-art emissions test chamber acting as a transient sink for organic emissions; the effect of increasing chamber concentration on the emission rate of the source. As a consequence of this mathematical development, a source emission rate as a function of time and a steady state emission rate factor are given precise definitions. Applications involve modeling 1,4 dichlorobenzene emission from moth crystal, and mixed emissions from latex caulk.
