Abstract:Bake-out exhaust method was used to significantly accelerate the release of VOCs from building materials. This paper studies the bake-out technology with dilution ventilation for indoor air pollution by experimental works. The baking effectiveness of formaldehyde, benzene, toluene and xylene ranged from 3 to 7.6, 7.6 to 25, 5.1 to 17 and 6 to 22 for the six cases, respectively. Baking effectiveness would become higher at longer baking time and higher baking temperature for formaldehyde and VOCs released from decorative materials. However, considering the possible deformation of building materials, 40 degrees C and 10 hr would be the best choice for a suitable bake-out.
