Abstract
A compressor control system includes at least one variable compressor, at least one fixed-capacity compressor, and a controller. The controller modulates the variable compressor based on a suction pressure reading of the variable compressor. In addition, the controller selectively toggles the fixed-capacity compressor between a run mode and a shutdown mode based on an operating parameter of the variable compressor.
