Effect of composition and temperature glide on heat transfer during flow boiling of refrigerant mixtures.

Einfluss der Zusammenstzung und des Temperaturgleits auf den Wärmeübergang beim Strömungsverdampfen von Kältemittelgemischen.

Author(s) : WETTERMAN M., STEINER D.

Type of article: Article

Summary

Heat transfer and pressure drop of the refrigerant mixtures R116/R134a and R116/R846/R134a are measured in a horizontal plain evaporator tube. The experiments are performed to demonstrate the effect of mixtures on the heat transfer and to determine basic data enabling design of refrigerant evaporators.
