| Abstract |
The VOCs and HCHO, which spout out the various construction material, become issue in mass communication and it has been emerged from problem of the society. One of the solution, photocatalyst had sold for market several years ago. However, without accurate analysis and effect, it has sold for photocatalyst to many consumers. After this study starts on the basis experimentation, existing apartment houses and newly building apartment is to examine the difference of IAQ. Also, it examines improvement effect about the produced VOCs and HCHO from the IAQ. The results are as follows: In comparison with Japan, the TVOCs is 16 times as high as and HCHO is decuple in newly building apartment. Taking measurement TVOCs and HCHO without furniture and home appliances, they will expect a higher numerical value, because of furniture and home appliances to install after move into a new house. In case of newly building apartment by photocatalyst coating, TVOCs are 15 times lower than Japan in Newly Building Apartment. But, HCHO is showed in excess of 0.03 ppm. From fundamental test 1 and 5, when appling in Newly Building Apartment, this study has been proved improvement effect against IAQ. |
