Abstract |
Some studies have shown that air temperature and humidity have a strong impact on the perception of air quality or VOC emissions from building materials. The objective of this study is to analysis of the impact on the formaldehyde concentration in apartment housing relation with air dry-bulb temperature, relative humidity and enthalpy. This study evaluated the indoor air quality in 567 new apartment houses in Korea from February 2006 to November 2009. Formaldehyde were sampled and analyzed by GC/MS and HPLC. Environmentally sound finishing materials were used in every households. The results of experiments, formaldehyde concentration showed the average value of 114.5 μg/m3, and maximum value of 799.3 μg/m3 in total experiments period. As a results, It was found that extremely exponential increased formaldehyde concentration, above air temperature 20oC, relative humidity 40%, enthalpy 40 kJ/kg. And it was observed that the most strong impact of enthalpy on the emission of formaldehyde from indoor air and building materials. |
