The paper presents experiment results of emission rates of HCHO from Medium DensityFiberboard (MDF, JIS grade E2) using three different test chambers. In this study, a full-scale stainless steel test chamber (19.68m3), a boundary layer type small test chamber (0.4m3), and a field and laboratory emission cell (FLEC, 3.510-5m3) were used. The coefficient of air change performance within the three test chambers was examined by CFD analysis. The convective mass transfer coefficient of HCHO from MDF was computed by CFD and the emission experiment. The CFD analysis and experimental results showed that the convection resistance on the boundary surface of the porous material could not be ignored compared with the diffusion resistance within the porous material.
