Summary

EXPERIMENTAL DATA ON THE EVAPORATION OF PURE R12 AND OF THE MIXTURE R12/HF12-16, DURING FORCED MOVEMENT IN HORIZONTAL TUBES, ARE PRESENTED. THE INFLUENCE OF THE STATE PARAMETERS ON THE SURFACE HEAT EXCHANGE COEFFICIENT IS ANALYZED. AN EQUATION FOR THE CALCULATION OF THE LOCAL SURFACE COEFFICIENTS WAS OBTAINED, AS A FUNCTION OF THE TUBE LENGTH DURING PURE R12 EVAPORATION. A RELATION FOR EVALUATING THE INFLUENCE OF THE MATERIAL OF THE TUBE WALLS ON THE MEAN SURFACE EXCHANGE COEFFICIENTS IS PRESENTED, AS A FUNCTION OF THE TUBE LENGTH.
