Only one chiller was ever online, the #2 chiller never came online. The chillers were piped in parallel, and the water from the two chillers mixed before re-entering the
building. These chillers were designed to run together, but were being controlled as a primary unit and a redundant unit. So as chiller #1 cooled the water, chiller #2 heated it back up.
Sometimes the subcontractors for individual systems do not ensure that their system is working correctly with other systems to accomplish the overall design objective.
Verify that subcontractors are not only strictly following their own specs, make sure the systems they are working on are compatible with all other systems in the facility.
