ShareInvestigation of evaporative heat transfer of refrigerants HFC-134a and HCFC-22 inside a smooth horizontal tube: comparison of experimental results and new correlations.
Etude du transfert de chaleur lors de l'évaporation des fluides frigorigènes HFC-134a et HCFC-22 à l'intérieur d'un tube lisse horizontal : comparaison des résultats expérimentaux avec les nouvelles corrélations.
Author(s) : BERRADA N., ALJ A.
Summary
A straight coaxial test section was used. The refrigerant evaporates inside the inner tube and hot water flows inside the surrounding circular ring area, providing the refrigerant with heat. Comparison of experimental results and various models enabled selection of the most suitable transfer law.
