Experimental study of condensation of the zeotropic blend HFC-23/HFC-134a inside a smooth horizontal tube.

Etude expérimentale de la condensation du mélange zéotrope HFC-23/HFC-134a à l'intérieur d'un tube lisse horizontal.

Author(s) : BERRADA N., MARVILLET C., BONTEMPS A., DAOUDI S.

Summary

The testing cross-section was a straight exchanger. In the inner tube a refrigerant condensed, while water circulated in the opposite direction in the annular space. The authors tested the blend HFC-23/HFC-134a with several compositions. In the conditions in which they worked they noticed no gliding effect on the exchange coefficient. Pressure losses can be estimated with conventional correlations by using the physical properties of the blend.
