Enhancement of the Boiling Process of Refrigerants with High Temperature Glide and Low GWP

Open Access

Abstract

The paper presents the results of experimental studies of the enhancement of the boiling process of a zeotropic agent with high temperature glide inside tubes at a low heat flux density. It discusses the effect of three types of inserts on the heat transfer process and the flow resistances during boiling of R407C in vertical tubes. The experimental studies covered measurements of heat transfer coefficient values, flow resistance values and thermal efficiency in the measurement section.
