Evaporation of R1234yf, R1234ze(E) and R1234ze(Z) on Cu surface: A molecular dynamics study

Journal of Molecular Liquids, 2021
Abstract Understanding the interface phase transition behavior of the working fluid helps to improve the energy conversion efficiency of a thermodynamic cycle. In this study, the evaporation behaviors of R1234yf, R1234ze(E) and R1234ze(Z) liquid film on the solid surface are performed using molecular dynamics simulation.

Investigation on the performance of R1234ze(E) in absorption refrigeration and ejection refrigeration systems

Applied Thermal Engineering, 2019
Abstract To mitigate greenhouse warming and ozone depletion, trans-1,3,3,3-tetrafluoropropene (R1234ze(E), a kind of hydrofluoroolefin) has been developed by researchers as an environment-friendly refrigerant. To investigate which kind of refrigeration is suitable for R1234ze(E), the performance of R1234ze(E) in both the absorption refrigeration and ...

Experimental investigation for the solubility of R1234ze(E) in pentaerythritol tetrahexanoate and pentaerythritol tetraoctanoate

Fluid Phase Equilibria, 2015
Abstract The phase behavior of refrigerant with lubricant oil is an important issue for designing the refrigeration system. R1234ze(E) was proposed as a possible replacement for R134a recently. In this work, the p – T – x data of R1234ze(E) with pentaerythritol tetrahexanoate (PEC6) and pentaerythritol tetraoctanoate (PEC8) were obtained based on ...
