“…It was noted that the used mixtures do not allow to obtain better ORC plant performance than pure fluids. The results of the experimental study of zeotropic mixture R1234ze(E)/R1233zd(E) condensation in small BPHE are reported by Huang et al [16]. The modified correlation of the form used in the paper [14] gave good results on heat transfer prediction, with a mean absolute error ±4.2%.…”

“…By the authors' conclusion, the condensation in their experiments was controlled by shear. More zeotropic mixtures were analysed by the same authors in [17] at temperatures from 70 to 90 • C. A modified correlation of paper [16] for the same studied BPHE was adopted with a mean absolute deviation ±7.1%. It shows that in specific process conditions at the same BPHE, accurate enough correlations can be obtained.…”

“…The pressure drop in condensation inside the vertical PHE of the water-ethanol mixture was studied by Hu and Ma [48], and a new friction factor correlation was developed with a mean absolute deviation from experimental data of 18.67%. Experimental studies of pressure drop during zeotropic mixture R1234ze(E)/R1233zd(E) condensation [16] and R134a/R245fa mixture were correlated with accuracy ±30%. For condensation of R-1234ze(E) and R-1233zd(E) refrigerants in small BPHE, the accuracy for the proposed friction factor correlation ±20% was reported in [18], but deviations from other data are much bigger.…”

Increasing energy usage efficiency requires enhanced heat energy recuperation between process streams in the industry and civic sector with waste heat utilization. The condensation of different vapours is the process encountered in many industrial applications. Increasing the heat recuperation in this process is possible with efficient heat transfer equipment, among which a Plate Heat Exchanger (PHE) is at the leading position. A number of research works have been conducted in recent years concerning construction development and heat transfer enhancement in conditions of limited pressure drop to increase PHE performance in condensation processes. The results of studies on heat transfer and pressure drop in the two-phase condensing flow inside channels of PHE with different geometries of corrugations are discussed. In many implementations, the total pressure drop allowable for gaseous streams in heat exchangers is relatively small. The structure of two-phase flow in PHE channels of complex geometry is very different than in tubes and flat wall channels. The relative differences in approaches to enhance PHE performance in condensation processes based on its modelling, optimisation and design are analyzed. The directions and prospects for future developments are formulated, and potential savings for the economy and the environmental footprint is presented.
