Abstract
A method of operating a refrigeration system uses a plurality of compressors in connected parallel. The method includes returning refrigerant and oil to the compressors, the refrigerant also having oil entrained therein, separating the oil entrained in the refrigerant, and returning more of the oil entrained in the refrigerant to a lead compressor of the plurality of compressors regardless of whether the lead compressor is operating. The method also includes connecting the oil sumps of all of the plurality of compressors such that oil is supplied from the lead compressor to at least one non-lead compressor of the plurality of compressors when the at least one non-lead compressor is operating.
