1. A rotary screw compressor system, comprising:
a housing including a surface defining at least a portion of an internal working fluid volume free of oil, at least a portion said surface including an abradable coating; a first pair of oil lubricated bearings; a second pair of oil lubricated bearings; a male screw rotor rotatable on said first pair of oil lubricated bearings, said male screw rotor having a first outer surface disposed within said internal working volume; a female screw rotor rotatable on said second pair of oil lubricated bearings, said female screw rotor having a second outer surface disposed within said internal working volume and intermeshing with said male rotor, at least one of said outer surfaces including a second abradable coating; a power source coupled with and operable to rotate said rotors; a temperature controller in fluid communication with said internal working fluid volume and operable to deliver a quantity of water to the working fluid within the internal working fluid volume to remove a portion of the heat of compression to obtain a predetermined discharge temperature for the working fluid without flooding the internal working fluid volume; and wherein the internal working fluid volume is isolated from said oil lubricated bearings to isolate the working fluid from oil contamination. |
