I have a carrier chiller that has had a ongoing issues with low load surging and they will also not load up. Both machines run between 5% and 15% guide vane position.
I adjusted T1 and P1 so the unit is always in HGBP mode to keep to machine on line.(2 machines).
Any advise would be appreciated.
This is my current operating conditions-
Condenser water - 74.6 / 77.3
Evap water - 52.4 / 50.5
Refrig - 81 / 48.2
Inlet guide vane- 5%
Motor- full speed @ 55% amps
