EFFECT OF OIL CONTAMINANT ON HEAT TRANSFER COEFFICIENTS IN REFRIGERANT EVAPORATORS.

INFLUENCE DE LA PRESENCE D'HUILE DANS LE FLUIDE FRIGORIGENE SUR LE TRANSFERT DE CHALEUR A L'EVAPORATION DANS UN TUBE HORIZONTAL.

Author(s) : MALEK A.

Summary

BOILING HEAT TRANSFER COEFFICIENTS USED FOR DIMENSIONING EVAPORATORS ARE GENERALLY THOSE FOR PURE REFRIGERANTS. HOWEVER, IN MANY CASES THE REFRIGERANT CONTAINS SOME OIL. THE STUDY COMPARES HEAT TRANSFER COEFFICIENTS FOR R12 MIXED WITH TWO DIFFERENT TYPES OF OILS. RESULTS SHOW THAT THE PRESENCE OF OILS ALTERS STRONGLY THE COEFFICIENT OF HEAT TRANSFER IN THE EVAPORATOR, THE ALTERATION DESPENDING UPON THE TYPE OF OIL AND ITS AMOUNT IN THE REFRIGERANT.
