Abstract An innovative system to recover part of the energy from man-made wind resources is introduced. A vertical-axis-wind-turbine (VAWT) with an enclosure is mounted above a cooling tower
Frequently-asked questions (FAQ) about wind-powered ventilation exhaust turbines, how they exhaust air, can they withstand adverse weather, how big and loud and warranty questions answered.
The feasibility of integrating the designed energy recovery wind turbine generator above an exhaust air system was evaluated by performing a series of tests on a fabricated small scaled
It is another object of the present invention to provide a system to generate electricity and/or mechanical power using wind energy when there is no exhaust air.
This research aims to design an exhaust air energy recovery system using a Savonius-type wind turbine and to investigate its performance. The prototype design was created using
This study investigates the potential of utilizing exhaust air from ducts in industrial or ventilation systems as a resource for wind turbine energy generation.
Because the rotary roof turbine vents are completely wind-driven, they require no electrical operating or wiring costs. Their economical design requires very little maintenance, has a low structural impact,
Data on airflow rates, exhaust fan specifications, and relevant parameters are collected and analyzed to understand the potential energy available for wind energy recovery.
This system generates on-site clean energy using a micro wind generation system. A vertical axis wind turbine (VAWT) with an enclosure is mounted above a cooling tower''s exhaust fan
To avoid a negative impact on the performance of the cooling tower and to optimize the turbine performance, the determination of the VAWT position in the discharge wind stream was
