Study on ventilation performance of inclined solar chimney coupled with indoor heat source

Abstract

The study of ventilation air distribution of the building with built-in heat source and set inclined solar chimney is carried out through 3D numerical simulation. The synergistic effect of thermal plume formed by internal heat source and solar chimney effect is analyzed. The effects of different solar radiation intensity I, heat flow density W at the surface of the internal heat source and structural parameters (including the height of the internal heat source from the ground h and the mezzanine inlet spacing b) on the indoor natural ventilation performance of the building are investigated.
