Enhanced method of lubrication for refrigeration compressors

A refrigeration system comprising:

• a compressor for compressing a refrigerant, the compressor having a first inlet and a second inlet, separate from the first inlet;
• a condenser for cooling the refrigerant;
• an evaporator for heating the refrigerant, the evaporator being fluidly connected to the first inlet of the compressor;
• and
• a lubrication system for providing a lubricant mist to a movable component of the compressor, the lubricant mist being carried by the refrigerant to the movable component, the lubrication system including:
• a first ejector arranged in fluid communication with the second inlet of the compressor and with the evaporator, wherein a stream of refrigerant is expelled from the first ejector and the stream of refrigerant has droplets of lubricant entrained therein;
• a tank, wherein the stream of refrigerant having droplets of lubricant entrained therein is provided to the tank;
• and
• a secondary ejector arranged in fluid communication with the compressor and the tank, wherein the secondary ejector has a primary inlet and a secondary inlet, the primary inlet of the secondary ejector is coupled to the outlet of the compressor such that the refrigerant output from the compressor is a motive fluid of the secondary ejector.
