Study on VOC partition characteristics of fabrics in indoor thermal and humid environment

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Fabrics are widely distributed in residential buildings. Because of their porous structure characteristics of high porosity and large specific surface area, they have strong adsorption properties for volatile organic compounds (VOCs). In addition, the desorption can aggravate indoor air pollution and prolong the pollution period. Partition coefficient, as one of the characteristic parameters of VOC mass transfer in fabric, is sensitive to temperature and humidity. Based on the analysis of the heat and mass transfer process of fabrics, the quantitative relationship between the fabric partition coefficient, the moisture absorption and the relative humidity of the environment was derived, and the prediction model of the fabric partition coefficient under the coupling of temperature and humidity was proposed. Three kinds of indoor typical fabrics were selected for a series of experimental tests to verify the accuracy of the prediction model. This study aimed to improve the predictive accuracy of indoor VOC concentration and help to set corresponding environmental control strategies.
