An oil separator for a refrigeration system employing a screw compressor includes a generally cylindrical, vertically upstanding housing the bottom of which defines an oil sump and the top of which is penetrated by discharge conduit connecting the oil separator to the refrigeration system condenser. The center line of the discharge conduit is parallel to but offset from the center line of the separator housing so that the discharge conduit is non-concentric with the housing. As a result, an enlarged tangential inlet to the interior of the separator is made possible which is unimpeded by the discharge conduit. The cross sectional flow area through which the mixture discharged from the compressor passes prior to entering the separator can therefore likewise be increased. As a result, pressure drop in the refrigerant gas as a result of the oil separation process is reduced and overall system efficiency is enhanced while the diameter of the separator housing is minimized.
