Abstract

A combination superheater and oil separator for a refrigeration system having a rotary component, a source of heated medium and a source of non-superheated refrigerant gas-oil mixture includes a sealed casing, a heat transfer unit within the casing having a heat transfer surface, a connection from the interior of the casing to receive the mixture from the source, a connection from the heat source to supply heated medium at a temperature and heat transfer rate through the heat transfer surface to boil off refrigerant gas from the mixture and produce superheated refrigerant gas, a connection on the interior of the casing to deliver superheated refrigerant gas boiled off from the mixture in the interior of said casing, and a delivery conduit to deliver oil from the casing to the rotary component for lubricating the component with the nondiluted oil.
