A Sensitivity Study of some Parameters on the Efficiency of a Passive Ventilation System Based on Solar Chimney

Article Preview

Abstract:

The purpose of this work is related to passive ventilation system analysis based on solar chimney. It consists in the determination of the temperature distributions of the wall, the glazing, and along the airflow in the chimney. The air mass flow rate and the instantaneous efficiency of the solar chimney were also determined. The energy performance of the solar chimney has been studied versus some geometrical and environmental parameters. The sensitivity study of the influence of some parameters on the efficiency of the system is also analysed. It is shown that the incident solar radiation has an important role on the energy performance of the solar chimney. Obtained results are compared to those of the literature. Good agreement is observed between the different results.
