Abstract
This study explains the experiment for evaluating the performance of small-sized wind power generators, in which outdoor air that increases with height of high-rise apartment buildings is induced into the exhaust openings of kitchens and bathrooms. This outdoor air generates an ascending air current and a certain amount of electric energy, which are needed for operating buildings. To apply small-sized wind power generators to exhaust openings of kitchens and bathrooms in existing apartment buildings, a constant driving wind velocity of 3 m/s is required. Performance experiments in laboratories and application experiments on building rooftops, in which outdoor air induction modules were applied to existing exhaust openings of kitchens and bathrooms, show that when outdoor air and exhaust wind velocity are lower than 2 m/s, a driving wind velocity of higher than 3 m/s, which is needed to generate wind power, can be obtained. Furthermore, the generated amount increases by 29%.
