Abstract:

Volatile organic compounds(VOCs)emitted from building materials can influence indoor air quality. Based on small ventilated chamber, a method for measuring the VOCs emission characteristic parameters(including the mean initial concentration, the partition coefficient)of particle board and the convective mass transfer coefficient was presented. In this paper, parameters estimation of particle board P1 and P2 from Heilongjiang were calculated, and the relationships between the VOCs parameters of the board and temperature were discussed. The testing methods and measurements of the model can be used to guide the selection of building materials and for evaluating the emission characteristics of building materials, evaluating and forecasting indoor air quality.

Key words: volatile organic compounds(VOCs), emission modeling, mass transfer coefficient, partition coefficient
