Technical description
liquid/vapour mixture, which rises to the receiver, dropping out the remaining liquid before allow-
ing the vapour to return to the condenser, completing the cycle.
Piping arrangement for thermosyphon oil cooling systems
The components and piping of a thermosyphon oil cooling system include a liquid source at con-
densing pressure, adequate static heads to provide fluid flow, appropriate control valves, safety
relief valves, service valves and pump-out connections. The arrangement of component place-
ment and fluid flow requirements must be designed to suit the individual refrigeration system lay-
out with consideration given to piping safety practices.
The component and piping arrangement in Fig. 37 is intended only to illustrate the operating prin-
ciples of thermosyphon oil cooling. Other component layouts may be better suited to a specific in-
stallation. For additional information on Thermosyphon Oil Cooling, please refer to Frick
publication 070.900-E.
