Condensation and evaporation of new refrigerants in advanced micro-finned tubes.

Summary

Micro-finned tubes optimized for finned tube heat exchangers as for shell and tube evaporators and condensers are one of these recent techniques which may allow enhanced performance of refrigerating units with the new refrigerants. Two thermal correlation models have been established resulting from experimental measurements on single micro-fin tubes: in evaporation, the model is a modification of the Gungor-Winterton correlation which concerns the addition of nucleation and convection processes within the inner grooves. In condensation, this model is a modification of the Cavallini-Zecchin correlation.
