ABSTRACT:
A method of staging a plurality of compressors in a refrigeration system. The method comprises the steps of: accumulating a first operative condition for each compressor; accumulating a second operative condition for each compressor; initiating operation of whichever compressor has the lowest accumulation of the first operative condition whenever a system controller calls for an increase in system capacity; and terminating operation of whichever compressor has the greatest accumulation of the second operative condition whenever the system controller calls for a reduction in system capacity.
