Résumé

The paper presents a test, which has been carried out in order to create a base to computation and design of condensers for a domestic refrigerators working with hydrocarbon mixtures as refrigerant. This subject was chosen because there is a significant amount of domestic refrigerators using hydrocarbon mixtures as refrigerant, and there are no correlations for heat transfer coefficient of condensing hydrocarbon mixtures. In the theoretical part, a mathematical model of the condensation process for binary hydrocarbon mixtures inside the tube in the vertical condenser was created and calculated. In order to calculate the heat transfer coefficient, correlations for CFC and HCFC mixtures were used. In the case of condensation, modelling results were compared with results of experiments by use of a thermograph method. Based in this analysis, some of empirical correlations were proposed to calculate the heat transfer coefficient for condensing hydrocarbon mixtures.
