Refrigerant condensation in vertical pipe minichannels under various heat flux density level

Abstract

This work is a study of the condensation process taking place in the conditions so far unproven. It was devoted to selected problems accompanying the condensation phenomenon occurring in a mini scale. The work is a continuation and development of the authors' research to-date. Paper describes the flow condensation of high-pressure refrigerants through channels made of stainless steel AISI 304 and AISI 316L with various inner diameter di. A new heat transfer universal correlation was developed on the basis of own experimental data for high pressure refrigerants condensation in pipe minichannels.
