Hello fellow members,
I just want to recall my HVAC knowledge if it still applies.
Say, I have a cooling coil with 33Ft. PD @ 125 GPM, my old school knowledge says that I should a control valve with a CV of 8-9. Will that change if I have VFD in the chiller system?
I appreciate any comment to help me boost my confidence in HVAC
Thanks.
