This project mainly uses experimental methods to conduct experimental research on the ventilation characteristics of inclined solar chimneys. The experiment is based on inclined solar chimneys and tests the thermal performance of inclined solar chimneys under different conditions and different operating modes. The influence of parameters such as temperature field and ventilation capacity is analyzed,and the experimental results are analyzed and sorted out. The effects of ambient temperature,tilt angle,and heat flux on the temperature distribution of the inclined solar chimney are analyzed. As a result,the depth of recirculation depth is obtained at different tilt angles. This study is of great significance for the development of low-energy building environments and the full utilization of solar energy.
