Abstract: A flash gas bypass system includes a separation assembly having an inlet configured to receive a refrigerant flow from an expansion valve. A bypass conduit is coupled to a first port of the separation assembly and configured to receive a first portion of the refrigerant flow via the first port, where the first portion of the refrigerant flow includes flash gas. A second port of the separation assembly is coupled to an outlet conduit in fluid communication with an evaporator. The outlet conduit is configured to receive the second portion of the refrigerant flow via the second port and direct the second portion of the refrigerant flow toward the evaporator, where the second portion of the refrigerant flow includes liquid refrigerant. A filter is configured to redirect droplets captured by the filter from the first portion of the refrigerant flow into the second portion of the refrigerant flow.
