Abstract

FLEC (field and laboratory emission chamber) is becoming a standard method to characterize pollutant emissions from building materials. Up until now, only the emission rate profiles are obtained, which are useful for the comparison and ranking of emission strength from different materials. However, to use the chamber emission test data to model pollutant concentrations in real buildings, and also to evaluate the effects of various control strategies, mass transfer model is required. As the first step, surface convective mass transfer coefficients are essential. In this study, a first series of direct measurements of surface mass transfer coefficients using distilled water at 5 air flow conditions ranging from 186ml/min to 509ml/min in a standard FLEC is conducted. Mass transfer data inside the FLEC is correlated by a dimensionless equation.
