  • SCREW COMPRESSOR WITH OIL INJECTION AT MULTIPLE VOLUME RATIOS
    Publication number: 20230349384
    Abstract: The present disclosure is directed to a screw compressor system having a compressor housing with a pair of screw rotors rotatably supported within a compression chamber. Lubricant is injected into a compression chamber at a first volume ratio and at a second volume ratio greater than the first volume ratio to increase the sealing and lubrication between the screw rotors and rotor bores in the compressor housing as well as to increase heat transfer from a compressed working fluid in the compression chamber.
