Dual AHU Supply system

[asommer]

I am putting together a supply system that utilizes 2 air handling units on one supply air loop system.  I had configured the Supply connectors on the unit to "System" and utilize a "Flow Factor", but the flow values do not work within the loop, therefore i cannot use Revit to size the duct properly.  Any ideas?  I had seen this system before, but couldn't get revit to work with it.

In general, Revit doesn't really handle loop systems very well.

Having said that, if you could post a small sample file, perhaps we can find a workaround.

Thanks for your reply, Chris.  I understand, and it is difficult to really know what is going on in a loop system.  I can probably create some dampers that will allow me to break the loop.  I'm suprised that more haven't asked about loop systems, or dual equipment on a system.  These types of systems are non-typical, but are used in large office (non medical) buildings.

If i get a chance, I will post a sample of what I am trying to accomplish.

Thanks again
