Abstract

The diffusion coefficient (D), partition coefficient (K), and initial emittable concentration (C0) are three key parameters to characterize the volatile organic compound (VOC) emissions of building materials. It is important to determine the accurate VOC emission characteristic parameters for evaluating indoor air quality and selecting appropriate control strategies. In this paper, a fast and accurate airtight chamber method was proposed for determining the VOC emission characteristic parameters. Through deriving the relationship between the characteristic parameters, the fully explicit analytical solution for the VOC concentration in the airtight chamber was expressed as a correlation of K. Based on the normalized relative sensitivity coefficient, the experimental data of gas-phase VOC concentration in the airtight chamber were fitted nonlinearly, and the values of the emission characteristic parameters were obtained. In addition, this new method was validated and compared with a well-recognized experimental method, and showed advantages in efficiency, accuracy and operation convenience.
