A screw compressor (12) for use in a chiller assembly (10) includes cooperating screw rotors (22, 24, 26) configured to increase the pressure of a vaporized refrigerant flowing through the compressor (12), a venturi tube (50) arranged in a flow path of the refrigerant in the compressor (129) downstream of the rotors (22, 24, 26), and an inlet port (46) in fluid communication with a throat of the venturi tube (50) and configured to deliver liquid refrigerant from a condenser (16) of the chiller assembly (10) to the flow path of the refrigerant in the compressor (12). The venturi tube (50) is configured to cause a pressure drop in the refrigerant in the compressor (12). The liquid refrigerant delivered from the condenser (16) reduces pulsations in the pressure of the refrigerant discharged from the compressor (12). |
