Abstract: A method for managing oil in a running multi-compressor refrigeration system including a controller and a multi-compressor device, includes monitoring an oil level in the oil sump of each compressor through the respective oil level detection device; detecting that a lack of oil situation occurs in a running compressor, if the oil level in said running compressor reaches a predetermined threshold condition; performing an oil managing action if a lack of oil situation is detected for a running compressor, the oil managing action being based on a changing of ON/OFF configurations of the compressors in the multi-compressor device and including performing an oil balancing action, if more than a half of the total number of compressors are running, or performing an oil returning action, if a half or less of the total number of compressors are running.
