A vapor compression refrigeration system comprising a compressor, a condenser, an expansion device, and an evaporator connected to form a refrigeration circuit. The system also includes a modulating valve and control means therefor for modulating a flow of refrigerant from the evaporator to the compressor to control the refrigerant flow through the compressor and the capacity of the refrigeration system. The refrigeration system further comprises a bypass line, a quench valve, and control means therefor for interjecting condensed refrigerant into the refrigeration circuit prior to the compressor and subsequent to the modulating valve in response to a predetermined refrigerant flow rate through the compressor.
