B-7 A study on prediction method of indoor formaldehyde concentration based on HCHO emission rate measured by the test chamber method : Part5 Verification of the prediction method in consideration of the background concentration

Abstract

In this study, an equation for predicting formaldehyde emission rate in consideration of the background formaldehyde concentration using the test chamber method is proposed to establish a simple prediction method of formaldehyde concentration in indoor environment. Although the steady state concentration from the formaldehyde-emitting material can be expressed by using HBF (Hoetjer-Berge-Fujii) equation, the equation does not consider the background formaldehyde concentration. Thus we derived prediction equation of formaldehyde from HBF equation in consideration of the background formaldehyde concentration and verify the expressiono
