摘      要：A coupled heat and formaldehyde migration model based on the non-equilibrium thermodynamic theory and molecule movement theory was developed.The effect of temperature on the transport coefficients was simulated,and the simulation results were validated with experimental data from the literatures.The calculation shows that air exchange rate larger than 2 h-1 should be prevented,if the purpose is only for formaldehyde emissions control.The effects of temperature on formaldehyde migration are obvious.
