Prototype development of the roof top turbine ventilator powered by hybrid wind and photovoltaic energy

For that study, a prototype of the rooftop turbine ventilator powered by hybrid wind and photovoltaic energy is developed. For the investigation of the prototypes ventilation performance, a low-speed wind tunnel experiment is performed. The experimental results are presented, they indicate that the installation of an inner fan at low outdoor wind speed (0 and 5 m/s) increases the ventilation rate whereas its installation at high outdoor wind speed does not improve the ventilation rate.
