Physical-based double-exponential model for VOCs emission from carpet
AbstractVOCs emission from carpet can be described by the mass transfer between the air adjacent to the material, and the room air. And the concentration in the air adjacent to the material is assumed to always keep equilibrium with the concentration in the material. Thus, a double-exponential model for VOCs emission is developed, which contains fast and slow decay terms. The present model is validated through the experiment in a small environmental chamber. The results from the present model accord well with the experimental data. Compared with empirical models, the present model has a clear physical meaning, is easy to scale up. It has only two parameters to determine from the emission test. The experimental results can be processed conveniently by linear fitting technique.
