  • Oil recovery and lubrication system for screw compressor refrigeration machine
    Patent number: 6672102
    Abstract: A vaporizer for boiling off a liquid refrigerant from a combined liquid refrigerant/lubricant mixture tapped from an evaporator utilizes hot compressed gaseous refrigerant tapped from a location upstream of the condenser. In a preferred embodiment, the refrigerant is tapped from a compression chamber within the compressor. The hot refrigerant efficiently boils the liquid refrigerant out of the mixture, ensuring high viscosity lubricant. In further features, a return lubricant line from the compressor passes into a sump to further boil off liquid refrigerant.
