Résumé

This work presents the results of an experimental study on pure refrigerant R134a and refrigerant-oil mixtures flowing through capillary tubes in order to analyse the oil influence in component performance. Tests were carried out for capillary tubes internal diameters of 0.69 and 0.82 mm, condensing temperatures ranging from 40 to 50°C, and subcooling degrees between 3 and 12°C. Pure refrigerant flow measurements were compared to those for refrigerant-oil mixtures with oil concentrations of 1.0 and 3.0%. [Reprinted with permission from Elsevier. Copyright, 2009].
