Abstract

The composition of decoration pollution is complicated and this paper takes formaldehyde as an example for research. In interior decoration, people often choose aesthetic program at the cost of pollution emission. The composition of decoration pollution is complex. This study takes formaldehyde as an example to study. Based on the finite difference method, this paper simulated the emission of formaldehyde by using CFD software. It mainly discussed the distribution of newly decorated buildings formaldehyde emission and the impact factors such as indoor compartment separation, windows opening form, cabinet furniture interior layout and wind speed in the typical houses. Under the condition of natural ventilation, the simulation results show that the formaldehyde concentration in the room with downwind direction is higher than that of upwind, and it inverses proportion to the wind speed. Therefore, increase the sweeping space of the through air and promote the emission of formaldehyde indoors that selecting doors and windows with large open area, reducing the partition of the indoor partition walls, and putting the furniture within local downwind direction.
