Shared Parameters for Air Flow

[brane1012]

Hi All,



as I was googling I found out that the usual way to define fresh air in AHU is like supply air, right? Now I am interested how to define parameters for flow on AHU connectors? I assume that they should be shared parameters, but do I need to assign separate shared parameter for each type of flow or one shared parameter is enough for all type? For Example, should I have:



Shared parameter = Air flow (used for all connectors on AHU), or should I have

Shared parameters = Supply Air Flow; Return Air Flow, Exhaust Air Flow, etc.



Best regards, Branimir.

Yes, separate them.

And how should I then define flow for let's say fire dampers? They can go in all systems (fresh, supply...)

Well, I would have a separate parameter but I would also have a generic air flow parameter which is used on families that are more universal. Make the connecter "Global" for system and link them together. If scheduling or using that parameter in a tag, just make sure you use the correct air flow parameter. If not scheduling or tagging flow, than it shouldn't matter.
