Hi everybody! I'm in trouble here trying to model a big VAV cooling system with 3 water chillers and 3 towers. In that case, what should be the best way to create chilled water loops with multiple pumps, since the hvac template doesn't do that? (although it allows me to create 3 chillers and 3 towers). In real life, what I've got here is a primary, seconday and condenser loops with 3 pumps each. Only the secondary loop uses variable speed pumps, the othes are single speed pumps. I've already tried to create the pumps "manually" but I always end up with lots of nodes and branches errors. I need to create those additional pumps in order to correctly simulate the reduction of electric consumption during the winter, when only one out of three pumps runs.
Thanks!
Robson
