Abstract: A climate-control system may include first and second compressors and a suction manifold. The first compressor includes a first shell, a first compression mechanism, and a first suction inlet through which working fluid is drawn into the first compressor. The second compressor includes a second shell, a second compression mechanism, and a second suction inlet through which working fluid is drawn into the second compressor. The suction manifold includes first and second arms. The first arm provides working fluid to the first suction inlet. The second arm provides working fluid to the second suction inlet. The second arm includes a first suction pipe, a second suction pipe, and a suction valve. The suction valve is movable between a first position in which working fluid is allowed to flow through the first suction pipe and a second position in which working fluid is allowed to flow through the second suction pipe.

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.
