Abstract
A controller and method for control of a refrigeration system having a compressor rack operable at a plurality of capacities may include determining a rate of change in suction pressure for a first capacity, determining a rate of change in suction pressure associated with a second capacity, and determining which of the first capacity and the second capacity will produce the least variation between a measured suction pressure and a desired suction pressure based on the rate of change in suction pressure associated with each.
