Abstract

In recent years, Dust haze has been a major health threat in southern and southwestern provinces of Iran, and Children suffer the most from Dust haze. Therefore, it is necessary to design educational centers to prevent the negative effects of walnut Dust haze. Exterior walls and windows are the most important routes for Dust haze to enter the classroom. Therefore, initially using simulation software, in addition to maintaining natural ventilation conditions, architectural elements reduce the amount of Dust haze penetration into the interior. The most important variables in this study are the distance between the walls and the amount of surface area. results show that increasing the distance between the two crusts results in a decrease in the wind flow velocity in this space and the Dust haze particle saturation. Slowing down will only work up to a distance of 200 cm, and then no change in wind speed will occur. Besides, the use of louvers in the inlet wind direction by directing the wind flow to the underside of the space between the two shells and reducing the level of air inlet leads to reduced wind velocity and particle saturation. Examination of the use of variable-angle louvers shows that the proper condition for creating natural ventilation conditions and reducing the penetration of indoor particles occurs when the louvers are angled relative to the 50-degree horizon.
