Abstract
In this study, an innovative rooftop turbine ventilator powered by a hybrid of wind and photovoltaic energy, “Hybrid Ventilator” for short, was developed. The performance differences between Hybrid Ventilators and conventional ventilators were assessed through a series of experiments. Then, CFD (Computational Fluid Dynamics) simulations were applied to survey the building ventilation efficiency of this Hybrid Ventilator. The results show that, considering the ventilation quantity (rate), a Hybrid Ventilator provides approximately 4 times the exhaust capacity of a conventional ventilator. All of the investigated space configurations that were examined via CFD simulations exhibited similar indoor airflow patterns and air velocity distributions (ventilation quality).
