Boiling heat transfer of new zeotropic mixtures

2019
The aim of the present work is to investigate the heat transfer performance of non-azeotropic ternary low global warming potential (GWP) mixtures when vaporizing inside two channels: a 8,0 mm inner diameter tube and a 0,96 mm inner diameter channel. The tested mixtures are R455A, which is a ternary blend of R32, R1234yf and R744 (21,5/75,5/3,0% by mass

Distillation of Nonideal Ternary Zeotropic Mixtures in Two-Feed Columns

Theoretical Foundations of Chemical Engineering, 2002
The continuous distillation of ternary nonideal zeotropic mixtures in two-feed columns is modeled. The results obtained are compared with the results of continuous distillation in one-feed columns. The topography of the field of relative-volatility coefficients is considered for various types of zeotropic systems.

Methods for predicting the condensation heat transfer of zeotropic mixtures of refrigerants

2001
Zeotropic mixtures of refrigerants could be advantageously utilised in some industrial applications. In fact, as their isobaric phase-change processes develop under non-isothermal conditions, the use of high temperature glide zeotropic mixtures allows an optimization of the temperature profiles in the heat exchangers and thus higher efficiency in some ...

Transfer from Carnot to Lorenz Process Using Zeotropic Mixtures

2002
The paper refers to the thermodynamic efficiency of the left hand cooling-heating process operating with a zeotropic mixture R407C that is compared to the process operating with a pure refrigerant R22. The measurements are performed on the experimental refrigerating system that enables operation according to Lorenz (zeotropic mixture application ...
