Effectiveness of Wind Turbine Ventilators

What's an AC sheet?

How silly of me. A cement roof. I should have know....................

I have seen these installed in a home and found that they are not rain proof. That may not be an issue in your situation. They do however allow hot air to escape. But in my opinion, no more than a hole in the same place.

I think this would do far more despite the operation cost...

Is there a gas leak, and if so, how close to it are you?

Hello Aravindg,

An ideal solution would be the 'whirlybird' self rotating bowl shaped turbines which operate through natural convection of hot air. The 'whirlybird' is fitted on the roof and the link provided below gives all details as regards the roof area per whirlybird etc. They are low maintenence devices and do not require electricity for operation. They should last for about 10 years and with a little bit of cleaning and lubrication last for about another 10 years. The potential fire hazard due to electricity is completely avoided. I do realise that LPG is a combination of heavy gases and tends to gravitate to the floor and therefore is not likely to reach roof level under careful operating conditions. The open shed is not likely to allow for the accumulation of gases as they would be blown away. I presume that you are working in India and in passing I may mention that I was managing the second largest LPG market (Gujarat) in India in the late sixties. The link is given below:

If you need anymore info. I would be glad to share my experience with you.

Yeah I am from India.Thanks for the guidance.I really appreciate it.

@DRFREON

There is no risk of Gas leak reaching the wind turbine during Standard operating conditions.Also, since it is LPG, it settles more in ground level.

This leads to entrapment of the hot air in the roof area and thus leading to the idea of WTV.

Is the hot air caused by the sun hitting the roof and the 2m stretch of cladding?

AC sheet in all sides for 2m from the top edge of the roof.

A building like yours would not stand a chance in Australia. It would have to at least be covered in two pack paint and this repeated every 3 years, to avoid fibers escaping and harming the population.

They have to do it with these two not far from were I am.

The good news is that I have a solution. The bad news: I am not ready to put the product on the market yet. If the heat of the sun is what is causing your problem you'll just have to wait.

There are other solutions but they require expensive architectural designs and that is not what you are asking for. It's best to be incorporated in the beginning anyawy.

Good luck, KY.
