Study On Simulate Of Diffuse Of Indoor Formaldehyde Pollution Induced By Residential Decoration Based On Airpak

In recent years, along with the improvement of life quality and the rise of" decorate hot", people use more and more materials in their indoor space for interior decoration. Those materials will send forth various harmful pollutants. The main kinds of pollutants which will be emitted are the formaldehyde, benzene, ammonia and the radio materials that will collect in the indoor space which is closing relatively. Among them, the formaldehyde caused domestic and international researcher's common concern for three reasons: the poison to human body to a great extent, the astonishing superscale in the decorated room and the long-term emitted time.This work based on CFD calculator imitation. The project is a small residence local in Shapingba District, Chongqing, which just pass by to decorate indoor space. In the project, the main work is surrounded in the distribution status and emitted of formaldehyde which is sent forth by decoration materials used in indoor decoration.Textual research way is:①Built up three dimension model of the whole set of residence, and imitate the fluid flow situation in the case of well natural ventilated environment;②Chose a room which had a typical emition model of formaldehyde, combined with above two research results, as the main research object. Establishment imitation model based on the practice physically circumstance. Imitation and research the fluid flow situation of formaldehyde in this room, and got detailed information of the pollutant density in this room;③Mensurated the concentration of formaldehyde in this room for 40 days after the indoor decoration was completed immediately. And got detailed data of formaldehyde density in different parts of this room. Then validated the possibility of calculator imitation by the data.④Imitated the different work conditions based on imitation model, and researched the influence coursed by changing of the indoor well ventilated.⑤Took order with the result, analyzed and contrasted with each situation, tally up the regulation of emition and distribution of formaldehyde in indoor space which was decorated. And then combined the conclusion together with actual application, used it as one of the standards to guide and repair indoor decorate. This object combines with the actual application closely and has the very greatly social need and applicability especially in the time that decoration industry develops very fast and heads for mature in our country. In the project we get many useful conclusions which have the actual application values by processing and analysis simulation result. These works can be used as basis and references in choosing experiment plan, calculating empirical formula and actual engineering application.
