The measure of the energy efficiency of the process is the heat transfer coefficient \u03b1, which<br \/>\ndepends on the kind of the two-phase flow. This article presents the influence of the two-phase flow structures formed<br \/>\nduring the condensation process in horizontal pipe mini-channels on the heat transfer process. The research was<br \/>\ncarried out on three pro-ecological low-pressure refrigerants with low ODP and GWP coefficients, HFE7000,<br \/>\nHFE7100, and Novec649.
