Low speed Variable Speed Screw Chiller
I was wondering what is the lowest speed that the compressor can go to on a variable speed screw chiller before the inlet guide vanes start to kick in. i assume it to be somewhere around 50% of Full Load speed but not sure.
Does this speed change at different conditions or with different manufacturers?

Re: Low speed Variable Speed Screw Chiller
In general minimum speed on most makes is 1440rpm .
This is because of rotor tip speed and sealing against casing .
