Abstract:
A material VOC emission model has been integrated with a zonal model to predict the transient VOC distribution within a ventilated room. This integrated zonal model is developed based on the conservation of air mass, energy and VOC mass. In the zonal model, the room is partitioned into coarse grids and Newton Raphson global convergent method is used to solve a set of coupled mass and energy nonlinear equations. In the VOC emission model, the material is divided into fine grids and control volume finite difference method is used to solve the transient VOC diffusion equation. This integrated zonal model is applied to a ventilated room with a carpet floor. It is found that VOC concentration is not uniform in the space and is influenced by the airflow pattern. The integrated zonal model can give a good prediction of the average VOC concentration in a room. Moreover, it is found that the integrated zonal model is a practical tool for the long-term VOC distribution prediction.
