Abstract

A screw compressor includes a screw compressor rotor (32). The rotor (32) includes a helical flute (36) extending outwardly from a rotor axis (38). A compressor housing (34) surrounds the rotor (32) and including a suction port (40) and a discharge port (42). The housing (34) has an inner housing wall (46) abutting the rotor (32) and an outer housing wall (50) forming an exterior of the compressor. A housing pocket (44) is located between the outer housing wall (50) and the inner housing wall (46). An economizer port (30) extends from the housing pocket (44) through the inner housing wall (46) to direct a flow of gaseous refrigerant into the compressor.
