Primary Secondary Zone Chilled Water System Functionality and Resources
Primary Secondary Zone Chilled Water System Functionality and Resources
(OP)
Hey everyone!
Got another question for the community. I am replacing two pumps (not headered) for two chiller pumps. The only graphic I've found anywhere that shows the kind of system I am working with is here. The fifth system described in this JMP article is nearly the same kind of system I have. However the main chiller plant on this loop has variable speed pumps with control valves on the chillers. The pumps I am replacing will be variable speed as well, but the chillers are constant speed wye-delta starting chillers with two-position control valves.
Does anyone have any/know of any resources that describes an example sequence of operations for a primary secondary zone water system?
Thank you,
Ian
