Problem with Y junction flow

marco.defina · ‎09-26-2017

Hello,

i have this situation:

I Have one duct with flow 40000 m3/h, i need to separate in two ducts for the Fire damper, after i need to return in a single duct with the same junction.

How i need to set the connector in the family? I receive everytime 0 of flow.

I setted so:

Duct Junction

Global

Bidirectional

Flow 2 on the little connectors

Flow 1 of big connector = Flow 2 * 2

Thanks

That sounds like it should work. Maybe you need to make that second Y a piece of equipment in order to recombine the air flows. Just a WAG.

Drafting is a breeze and Revit doesn't always work the way you think it should.

Hello,

I made a quick test, seems that you will need two fittings, one for splitting and another for joining, with different settings.
