초록

The paper deals with the numerical analysis of contaminants emission from the material affected by temperature variation in floor heating system. Considering mass transfer and heat transfer theories, a computer program for the analysis of VOCs emission was made. To demonstrate the accuracy of the numerical solution, the prediction results and the measured data were compared. Using this program, emission rates of the materials in the bakeout space and the no bake-out space were compared to estimate the variation of emission rate.
