Abstract

The integration of natural ventilation components has become increasingly desirable in the building sector as a means to enhance ventilation systems. Low carbon technologies, such as windcatchers and turbine ventilators, are commonly employed in commercial, educational, and industrial buildings for cooling and ventilation purpose. This study investigates a novel concept of home ventilation systems integrated with a vertical axis wind turbine, aiming to provide a detailed understanding of the system’s ventilation performance concerning both air extraction and supply using a turbine ventilator.
Performing Computational Fluid Dynamics (CFD) simulations, the 8-blade turbine ventilator achieved a maximum exhaust flow rate of 87.52 l/s at a wind speed of 6 m/s, exceeding the minimum ventilation rate. Additionally, the initial design of the air intake vent (AIV) was tested, resulting in a maximum air supply flow rate of 38.25 l/s at 6 m/s. Subsequent modifications to the AIV were made, yielding two variants: AIV1 and AIV2, which improved ventilation performance by 5% and 20% respectively.
Given that the proposed turbine ventilator is in its initial design phase, the numerical results demonstrate promising potential of the development of a home ventilation system integrated with the turbine ventilator. This study serves as a foundation for further research and optimisation of such systems.
