Hi,
I have a question regarding the chilled water pump power calculation in ASHRAE 90.1 Appendix G:
ASHRAE 90.1 Appendix G Paragraph G3.1.3.10 requires that "The baseline building design pump power shall be 22 W/gpm.". If the chilled water pumping system is a primary-secondary system, how does this rule apply? i.e. does the 22 W/gpm apply to the primary pump, secondary pump, or both? Or, do I need to divide it between the primary and secondary pump?
Your suggestions will be greatly appreciated.
Thanks,
Dongyi
