natural ventilation

[lattu]

if I have to ventilate an underground and completely isolated intercapedine (see diagram), does the fireplace effect work with a higher grip than the place to air?

the famous Iranian towers, used to refresh of course the environments even underground, go to intercept the air in the entrance also from higher positions than the environment to be ventilated.
in theory the chimney effect should occur. much depends then on the height of the outgoing air fireplace. in your case you should have at least 3 mt

between outlet mouth and yield mouth I have a variable height between 6 mt and 9 mt, so it should work.
Thank you.

with 6 / 9 meters you should not meet problems. rather, being a fireplace effect not generated by very hot air, such as the one generated by a fireplace, you should pay attention to the top of the duct that acts as a chimney so that the flow is not disturbed by the wind, at least by the prevailing wind, to avoid at most a possible flow of return. There are also smoke suction fans that do the case. or predispose the exit by repairing it from the predominant wind, as seen from the image I postedhttps://images-na.ssl-images-amazon.com/images/i/51rymp7tjml._ac_.jpg

Right, probably the best thing to do, thank you

Hello, are you doing ventilation for a fire escape?

 

[lattu]

no is an intercapedine that will have to act as a permeable trench anti-allocation

I've seen a kidney written next to me for that question. .

in this case the rei wall separates the enclosure from a compartment
