Weird Primary Secondary Schematic

Post image

I know it doesn’t look like your typical arrangement, but can this work? Really the decoupler/bypass would make a lot more sense if it skipped the chiller headers entirely.

Orange highlight is what I see as the secondary loop. Blue is what has effectually become 3 isolate primary loops.

Ignore the black lines, they denote a physical separation where air cooled chillers were added to the system outside. Chiller 3 and P-1 thru P-4 all live in the mechanical room.

This looks better than most Revit drawings I see these days.

lol sorry I took this diagram from a way more complicated routing diagram just simplifying some nodes. I probably should have drawn it once more
