AN EXPERIMENTAL STUDY ON THE INFLUENCE OF OIL ON HEAT TRANSFER IN GRAVITY FED, FLOODED EVAPORATORS.

Author(s) : FRIVIK P. E., CHRISTENSEN G. A.

Summary

THE PAPER DESCRIBES THE TEST RIGS AND METHODS USED TO CONDUCT EXPERIMENTS TO OBSERVE CHANGES IN THE OVERALLHEAT TRANSFER COEFFICIENT FOR TWO FLOODED R12 EVAPORATORS, IN WHICH DIFFERENT OIL CONCENTRATIONS WERE MAINTAINED. ONE EVAPORATOR WAS A PLATE TYPE, COOLING WATER. THE OTHER WAS AIR HEATED. IN THE PLATE TYPE EVAPORATOR THE HEAT TRANSFER COEFFICIENT INCREASED BY ABOUT 10% WITH AN OIL CONCENTRATION OF 2.5 TO 3.0% BY WEIGHT, AND RETURNED TO THAT FOR PURE REFRIGERANT WHEN THE OIL CONCENTRATION REACHED 6.0%. IN THE AIR HEATED EVAPORATOR OIL ADDED HAD A NEGATIVE EFFECT FROM THE START. D.W.H.
