[EnergyPlus_Support] How to split chilled water pump head when primary secondary system is used
Hi,
ASHRAE 90.1 G3.1.3.10 indicates that the baseline building design pump power shall be 22 W/gpm, equivalent to 90 feet head with 78% combined impeller and motor efficiency. And the chilled water system should be modeled as primary/secondary systems.
The question is: how to split this 91 ft head to primary and secondary chilled water pumps? They should be evenly distributed or there are some certain portions?
Any comments/advice are welcomed.
Sean
