Numerical value research on bake-out technology with dilution ventilation for building materials

Bake-out with dilution ventilation is a potential technology that can shorten emission cycle of indoor VOCs and other hazardous gas, and then reduce indoor environment pollution brought forward by building materials. This technology based on characteristic that chemical substance of building materials is easier to emit under high temperature. This paper used numerical value method to compute TVOC removal amount under different operation conditions and concentration changes indoor during bake-out exhaust dilution process.

Modelling of emissions of total volatile organic compounds in an Australian house.

A simplified indoor air quality (IAQ) model has been applied to predict IAQ in an Australian house, using environmental chamber measurements of source strengths, house ventilation and room size. Total volatile organic compounds (TVOCs) was used as the model pollutant in this study. The validity of the IAQ model was initially assessed by comparing model predictions with measurements in the house over a period of time. The root mean square error between the measured and predicted values was 0.039. This model explains 57% of the potential for error.
