An efficient code has been developed to predict dispersion of indoor air pollutants The computing capability of the code has been compared with that of a commercial code inn a benchmark test. After that, the code has been employed to compute dispersion of a pollutant released from a new furniture, a kind of Sick Building Syndrome (SBS). A sofa which generates formaldehyde is implemented by using an immersed boundary method. Large Eddy Simulation (LES) is employed to obtain time-dependent velocity and scalar fields. LES has bee regarded as an academic tool, but the newly-developed code reveals a possibility of application of LES to practical problems, especially dispersion of indoor pollutants.

Nowadays the number of people suffering from Sick House Syndrome have been increasing, especially after they move into a new apartment. The symptom varies with people and it develops gradually. It is known that the symptom is caused by chemicals. In spite of many unknown factors related to the symptom, lifestyle and behavioral factors of occupants were possibly. The purpose of this study was to find out the residents' self-reported symptoms of Sick Building Syndrome in new apartment houses. The response could be self-consciousness symptom, health damage and the improvement plan.

After that, the code has been employed to compute dispersion of a pollutant released from a new furniture, a kind of Sick Building Syndrome(SBS). A sofa which generates formaldehyde is implemented by using an immersed boundary method. Large Eddy Simulation (LES) is employed to obtain time-dependent velocity and concentration fields. LES has been regarded as an academic tool, but the newly-developed code reveals a possibility of application of LES to practical problems, especially dispersion of indoor pollutants.

실내공기오염은 한정된 공간과 밀폐된 환경으로 인해 대기오염 보다 더 중요한 문제가 된다. 호흡기 알레르기, 빌딩 증후군, 새집증후군으로 인해 폐렴, 천식, 피부질환이 늘어나는 등 건강상의 장해를 가져오는 문제를 갖는다. 그러므로 실내에 있는 환경오염 물질을 환기를 통해서 줄이고 건강한 생활 환경이 되도록 하는 것이 중요하다.

실내 오염 물질의 농도는 온도와 습도에 밀접한 관계가 있으므로, 실내온도는 18~22℃, 습도는 55% 전후로 유지하는 것이 좋다. 거실 등에 인체 유해물질을 흡수하는 식목을 배치하면 공기 정화에 도움이 된다.

When you move to a new home, or when you change the wallpaper or flooring of your home, office, etc., you can enjoy the joy of opening your new home with the sick house syndrome, such as the stinging smell and stinging eyes that may appear after the interior work. It is only a moment. Volatile organic compounds from building materials, adhesives, wallpaper, and paints used in new buildings or new furniture cause residents' health and discomfort in indoor life. These volatile organic compounds include benzene, toluene, acetone, and styrene, as well as the representative formaldehyde, and these substances are slowly released over a long period of time, causing acute or chronic diseases to residents. As a method for removing organic volatile substances, physical methods using adsorption, chemical methods for converting volatile substances to other substances, or a mixture of the two are mainly used. In this paper, a sustained release chlorine dioxide gel pack obtained by a method for controlling the reaction rate of a reactant and the release of a product is mixed with a zeolite adsorbent having an optimized hole diameter to adsorb and decompose and remove formaldehyde suspended in the air. I would suggest an effective method.
