Optimum design and analysis of the application of the air slot on the building horizontal sun-shading board

摘要

The sun-shading board is an important way to improve the indoor thermal environment. And air slot is the critical component to improve ventilation effect of sun-shading board. It not only can promote heat dissipation of sun-shading board but also can improve ventilation effect of building window. The shading coefficient of shading board and vorticity influence of air slot are the main principles of designing configuration and size of air slot. The horizontal sun-shading board of residential building south window in Nanjing is the study object. The shading and ventilation effect of shading board with various configurations and size is analyzed quantitatively. And appropriate configuration and size are obtained on the basis of comprehensive consideration of various factors.
