摘要
A control system for controlling the capacity of a lead compressor of a refrigeration system having a lead and lag compressor when the lag compressor is in surge. A microcomputer system receives electrical input signals indicative of the lead and lag motor currents and closes the inlet guide vanes of the lead compressor when the lag compressor percent motor amps are below the lead compressor motor amps by more than a selected percentage for a specified period of time.
