Two-phase heat exchange for new refrigerants and their mixtures.

Author(s) : STEPHAN K.

Summary

Existing correlations adequately describe the nucleate boiling and condensation heat transfer of pure refrigerants. Boiling and condensation heat transfer coefficients of mixtures are often considerably lower than those of the pure components. The reduction depends mainly on the difference between dew and bubble point temperature for a given concentration. It compensates often to a great extent the advantage of a gliding temperature difference. The paper shows a model recently presented by Steiner and Taborek and applies also for refrigerant mixtures. Results and conclusions are given.
