Abstract
A compressor system includes a first compressor and a second compressor. A suction equalization line fluidly couples the first compressor and the second compressor. A first branch suction line is fluidly coupled to the first compressor and a second branch suction line is fluidly coupled to the second compressor. A main suction line is fluidly coupled to the first branch suction line and the second branch suction line. An obstruction device is disposed in at least one of the first branch suction line and the second branch suction line. Responsive to deactivation of at least one of the first compressor and the second compressor, the obstruction device is at least partially closed thereby causing prescribed liquid levels in the first compressor and the second compressor during partial-load operation.
