Multi-compressor refrigeration units. Oil distribution problems
When the number of compressors running in parallel is equal to or greater than four, or when the compressors have different capacities (although parallel connection of compressors of different capacities and designs must be avoided), or the amount of oil returned is unknown, an oil level regulator (OLR) and oil separator (OS) system is preferable. With this system, the difference in pressure inside the crankcase of each compressor has no effect on oil level stabilization.
