The Research of Computational Method of Formaldehyde Density Influenced by Ventilation Factors in the Environment Test Cabin

The functional relation type about the release coefficient of the formaldehyde in the plate and the rate of air exchange is fitted on the foundation of the experiment about the relationship between the release co-efficient of the plate formaldehyde and the factor of ventilates with the environment test cabin simulated as the Indoor environment. In this way, the equilibrium concentration formula of the formaldehyde is theoretically obtained when the environment cabin is in the stable state on the specific rate of air exchange, and the formula has been experimentally confirmed. It is indicated that the experimental result is consistent with the formula-computed result. As a result, the computation precision of the formula can be further increased with the revision on some system errors of the formula after the analyses about the experimental results.
