<p>An oil separator (10) for a refrigeration system (100) employing a screw compressor (108) includes a generally cylindrical, vertically upstanding housing (12) the bottom of which defines an oil sump (16) and the top of which is penetrated by discharge conduit (26) connecting the oil separator (10) to the refrigeration system condenser (102). The centerline (28) of the discharge conduit is parallel to but offset from the centerline (30) of the separator housing so that the discharge conduit (26) is non-concentric with the housing (12). As a result, an enlarged tangential inlet (20) to the interior of the separator is made possible which is unimpeded by the discharge conduit (26). The cross-sectional flow area through which the mixture discharge from the compressor (108) passes prior to entering the separator (10) 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.</p> |
