Thanks Alan,
1- I have a air cooled VRV with outdoor unit the compressor work form 9% to 100% load, with max rpm 7890.
I need to the formulas that give me the rpm at 9% of the load, I was searching I found that HP1/HP2=(RPM1/RPM2)^2
with HP = horse power.
the compressor is reluctance...
I have max rpm value and i need to get the minimum rpm at 0.09% of the load.
if I have unit with 3 compressor 2 of 7980 rpm and one with 6300 rpm can i get the max rpm of the unit?
any help? thanks
