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. Except that, this paper also discussed effects of bake-out temperature, bake-out time, ventilation time, air change rate on removal.
