Chillers and pumps as well as Air Handling Units must be connected in parallel.
Each chiller must have a differential pressure sensor connected across inlet and outlet.
The pumping system must have a differential pressure sensor across inlet and outlet headers.
A differential pressure sensor will be placed between inlet and outlet of each zone served by the plant.
Electrically actuated chiller isolating valves are required for each chiller in the system.
An electrically actuated bypass valve must be provided between the outgoing flow to the zones and incoming flow to the pumping system and
chillers.
