| Abstract |
Because of the airtightness of building and abuse of furniture and misuse of building materials, indoor air pollution has been increasingly concerned with new apartment buildings. To improve the IAQ(Indoor Air Quality) in the pre-occupation new apartment, this study was aimed at surveying the emission rate of noxious materials in bedroom and living room during 3-weeks, analyzing the reduction rate of HCHO(Formaldehyde) and VOCs(Volatile Organic Compounds)by three ventilation types(Natural Ventilation, Mechanical Ventilation:using 15w toilet fan and 50w kitchen hood fan, Hybrid Ventilation). The results of this study are as follows; 1) Compared mechanical ventilation(using toilet fan and kitchen hood fan) with natural ventilation, the reduction effect of HCHO using mechanical ventilation is 1.2∼1.7 times better than natural ventilation. 2) The reduction rate of HCHO using toilet fan in bedroom during three weeks is 20%, TVOC using toilet fan in bedroom during three weeks is 90%. And the reduction rate of HCHO using toilet fan and kitchen hood fan in living room during three weeks is 60%, TVOC using toilet fan and kitchen hood fan in living room during three weeks is 96%. |
