Hello!
I have made a family from a fancoil of a manufacter.
I have input duct conectores for: Supply return and other air(Outddor air)
I have made ducts into airterminals.
I imput the specific air flow.
and then i ve tryed duct autosizing!!!
The answer is No airflow at zero section.
at horange happears the return duct.
Whats happening? Anyone can help?
NOTE: I am ataching the fancoil and return air terminal if someone wants to take a look.
Thnks Rui
Looks good but a few connectors are wrong. A couple of comments on your family:-
The Hydronic connectors should be preset not calculated as they specify the flows, etc. for the main upstream equipment.
Never use Other Air Connectors in HVAC systems (unless you have gas fired equipment) Other Air is for gas related systems such as Medical gases, compressed air etc.
What is the Bi-directional connector for?
You need to consider logically how Revit is going to calculate the flows through your systems and how the Supply Air connectors are linked to the fresh air supply and the return air.
As for your problem, maybe a couple of screenshotsof the layout, what you're sizing and the error message may help get a better answer
