Abstract

Although R-1233zd(E) has been considered as an alternative to R-245fa used in the organic Rankine cycle (ORC), experimental studies on the heat transfer characteristics of R-1233zd(E) in plate heat exchangers are limited. In this study, the evaporation heat transfer coefficient and pressure drop of R-1233zd(E) in a brazed plate heat exchanger are measured with respect to the mass flux, heat flux, saturation temperature, and vapor quality. As a result of the experiment in this study, the heat transfer coefficient of R-1233zd(E) is strongly dependent on the mass flux and vapor quality, and not on the heat flux and saturation temperature because the flow is in the convective boiling regime. The frictional pressure drop of R-1233zd(E) shows a strong dependence on the mass flux, vapor quality, and saturation temperature. Moreover, the heat transfer coefficient and pressure drop of R-1233zd(E) are compared with those of R-245fa. Finally, empirical correlations for the heat transfer coefficient and friction factor of R-1233zd(E) are developed based on the measured data.
