modelFlowMachine_m
Identical m_flow controlled pumps
Extends from Buildings.Applications.DataCenters.ChillerCooled.Equipment.BaseClasses.PartialPumpParallel.
Information
This model implements a parallel of identical pumps with m_flow being controlled.
The number can be specified by setting a value of num.
The shutoff valves are used to avoid circulating flow among pumps.
