EFFECTS OF BAKE OUT AS A SOURCE CONTROL TECHNIQUE FOR INDOOR CHEMICAL SUBSTANCES (PART 1) : A study on indoor air pollution by VOC and formaldehyde (Part2)

Experimental and simulation study on bake-out with dilution ventilation technology for building materials

“…Thus it can be seen that the removing effect of VOC is better than that of formaldehyde under the same conditions when applying bake-out exhaust dilution technology. The result is consistent with the research carried out by Nozaki (Nozaki et al, 2000). The main reason for these differences is that large quantities of benzene, toluene, and xylene are contained in water-based coatings and water-based adhesives.…”

“…The principle of this bake-out procedure is to drive the VOCs out of the construction materials into the indoor air by increasing the room's temperature to 32-40 °C, while increasing the outdoor air exchange to remove the emissions from the materials (Kang et al, 2006;Lu et al, 2012;Kim et al, 2010;Li et al, 2005;Park et al, 2007). Nozaki's studies showed that formaldehyde and VOC emissions were closely related with temperature (Nozaki et al, 2000). Renata Wiglusz's (Wiglusz et al, 2002) research about the effect of temperature on formaldehyde and VOC indicated that emissions are proportional to high temperature.…”

“…Researchers from the US, Japan, and Korea have already begun work on removing air pollution by bake-out method (Girman, 1989;Hodgson et al, 1994;Etkin, 1996;Wieslander et al, 1997;Nozaki et al, 2000;Kim et al, 2005). In Korea, actual residential measuring A c c e p t e d M a n u s c r i p t experiments have been conducted, with the aim of assessing the effect of baking.…”

Research on Bake-Out with Dilution Ventilation for Indoor Air Pollution

“…Bake-out with dilution ventilation is based on the characteristic that high temperature causes more chemical substance emission from building materials. This is a new method that can shorten emission time of formaldehyde and VOCs, and have absorbed great attention from all over the world [7,8].…”
