Abstract

A climate-control system may include first and second compressors, first and second suction valves, and a control module. The first and second compressors each include a shell and a compression mechanism. The shells define suction chambers from which the compression mechanisms draw working fluid. The shells include suction inlets through which working fluid is drawn into the suction chambers. The first suction valve may be movable between a fully open position and a partially closed position and may control a flow of working fluid through the first suction inlet. The second suction valve may be movable between a fully open position and a partially closed position and may control a flow of working fluid through the second suction inlet. The control module may control positions of the first and second suction valves to control lubricant levels in the first and second shells.
