The Study of a Classroom with Solar Chimney Hybrid Ventilation
In order to improve effect of hybrid ventilation, the paper discussed a solar chimney to enhance natural ventilation. Some factors influencing solar chimney hybrid ventilation in classroom, such as heat sources, air inlet arrangements, air velocity and solar radiation were studied by simulation and validated by experiments. The characteristics of temperature distribution and temperature efficiency in classroom were obtained and analyzed. A low position of air inlet in the room makes high temperature efficiency, the optimal value of the air inlet velocity is about 0.5 m/s. The research provides a better way to enhance hybrid ventilation by solar chimney.
