Evaluation of zeotropic refrigerant mixtures R32/R134a in flow condensation

摘要

Experiments on flow condensation have been conducted with pure R32, R134a and R32/R134a mixtures. The results have been represented in form of local and mean heat transfer coefficient, as well as pressure drop. The heat transfer data is comparedwith the prediction from correlations in literature. An analysis is also carried out on potential causes of heat transfer degradation associated with NARMs.
