Abstract (en)
[origin: WO2015006081A2] A screw compressor includes a screw compressor rotor. The rotor includes a helical flute extending outwardly from a rotor axis. A compressor housing surrounds the rotor and including a suction port and a discharge port. The housing has an inner housing wall abutting the rotor and an outer housing wall forming an exterior of the compressor. A housing pocket is located between the outer housing wall and the inner housing wall. An economizer port extends from the housing pocket through the inner housing wall to direct a flow of gaseous refrigerant into the compressor.
