[Virtual-sim] Natural Ventilation_Ducted OA/Relief

[Nikola Kravik]

Hi Shanta,

It's in relation to both; modeling this using IESve MacroFlo or MicroFlo(CFD) and also verifying/simulating the design of such NV system-to see if it will actually work/potential drawback I mentioned below.

Hello Nikola,
Is your question about modeling this (CFD?) or designing this?

Hi all,

Has anyone done successfully NV with ducted  OA Supply Intake/Ducted Relief?
Would you mind sharing few thoughts on the concerns/effectiveness of such system, especially if you don't have fans assisting the supply of the outside air into the space?

The OAS intake(s) are about 130-140 ft from the supply diffusers to the space and I'm worried about the ability of that air to travel using only the buoyancy/differential pressure effects. The relief is ducted, which I think may be an issue too.

I appreciate your feedback.

Regards,
Nikola
