Constant power production and harvesting using roof ventilation systems
MetadataShow full item record
Energy harvesting using horizontal wind turbines is investigated and a performance analysis is done and compared over a period of time using identical rooftop wind turbines. In many buildings, especially high rises, air ventilation systems are operated non-stop with a constant air speed. Real time applications are mainly used with vertical wind turbines, but they have limited efficiency due to wind airflow distribution. Small modifications on wind turbines and ventilator systems can improve the airflow of the vent systems as well as the efficiency of the wind turbine. Using ventilator systems can eliminate weather prediction modelling due to constant airflow and non-stop operation of the ventilator systems. This study shows that even though wind airflow may be stronger at various times during the day, the average power production using a ventilator system is quite large. The ventilator systems can be named a new renewable energy source due to their constant energy production possibilities.
