An overview of Wind driven Roof Ventilation System

 

Turbo Air Ventilation is a wind driven roof ventilation system which works on the principle of mechanical depressurization. It is a metallic dome with fins which rotate by wind action. The rotating turbine creates a low pressure region inside the dome and hence air from outside reaches to fill the gap thereby creating an air flow and fulfilling its purpose of ventilation. 

The system is made as such the friction is as low as possible. This gives the advantage to turbines to maintain the rotational momentum even when there is no or low wind action. Turbine ventilation system is now an easily recognizable structure and can be seen in industries, commercial spaces and for domestic purposes as well.  

 

The popularity of turbo air ventilation systems can be credited to the following factors:

v  Easy Installation – Turbine ventilation systems are easy to install and can be fitted on corrugated sheet rooftops and plain rooftops irrespective of the slope. These systems generally come with an attached base sheet which can be adjusted according to the slope yet keeping the turbines parallel to the ground.

v  Economical – Turbo air ventilation systems are economical as they are cheaper than other mechanical systems, require near to no or very low maintenance and are one-time investment. Additionally there is no requirement for electrical power for wind driven systems thus saving capital.

v  Weather Resistant – Turbine ventilation system is made up of industry standard materials and are resistant to extreme weather conditions. Besides metal polishing and varnish prolongs life by preventing corrosion. These structures are not affected by heavy rain and strong winds and dome shape makes them structurally stable.

v  Efficiency – Turbo air ventilation systems are efficient in their working and provide an economical aid to natural ventilation. Besides preserving the aesthetics of the building structure, turbine ventilation work all round the day keeping the inside atmosphere fresh and healthy.

Ventilation is an important criterion to consider while designing a building. Ventilation is necessary for homes to maintain fresh air flow, thermal and personal comfort; for factories ventilation is necessary to remove harmful air content and pollutants from the inside. Commercial spaces have ventilation to prevent the increase in Carbon Dioxide concentration and keep the environment fresh. 

The purpose of a building structure decides the efficiency needed for ventilation, some structures like water storage tanks just need natural ventilation while some industries like thermal power plant needs mechanical ventilation. 

Wind driven roof ventilation system such as the Turbine ventilation is for buildings which need ventilation in between natural and mechanical processes. Besides being economical and easy to install, turbo air ventilation systems are very much efficient in their working.
