Abstract
An oil separator for use in separating oil from refrigerant gas in a chiller system is provided. Its operation is based on centrifugal separation principles and does not require the use any type of filter or media pack to remove oil from refrigerant gas. The oil separator includes a non-circular (e.g., elliptical) refrigerant outlet pipe that transitions the linear flow from the inlet connection to a swirling (e.g., circular) flow within the cylindrical housing. The non-circular shape of the entrance to the refrigerant outlet pipe provides for more turbulent gas flow and a greater extraction of oil as well as minimization of pressure losses.
