Summary

THE INFLUENCE OF THE HF 22S-16 AND HS-40 OILS, DISSOLVED IN R22, ON THE SURFACE EXCHANGE COEFFICIENT AND ON THE HYDRAULIC RESISTANCE DURING THE EVAPORATION OF THE REFRIGERANT-OIL MIXTURE, WAS STUDIED. IT HAS BEEN ESTABLISHED THAT, WITH THE INCREASE OF THE OIL CONCENTRATION IN THE MIXTURE, THE EFFICIENCY OF THE HEAT EXCHANGE DECREASES AND THE HYDRAULIC RESISTANCE INCREASES. CONSIDERING THE HEAT EXCHANGE IN THE EVAPORATORS OF REFRIGERATING MACHINES, THE R22-HS-40 OIL MIXTURE IS LESS EFFICIENT THAN THE R22-HF 22S-16 OIL MIXTURE.
