4.29 Thermosyphon oil cooling
Thermosyphon oil coolers, like water (or glycol)-cooled oil coolers, eliminate the capacity and
power penalties associated with liquid injection oil cooling. Thermosyphon oil coolers have the
further advantages of eliminating water (or glycol) pump power consumption and maintenance,
fouling and potential system contamination.
The principle of operation is as follows, see Fig. 37. A supply of high-pressure liquid is maintained
in a receiver at a predetermined minimum head above the oil cooler and below the condenser.
Gravity causes the liquid refrigerant to flow to the oil cooler where a portion of the liquid is boiled
off, thereby cooling the hot oil. New liquid from the receiver displaces the lighter refrigerant
