This paper reviews the most relevant research on R1234ze(E) (pure and mixture).
Property, heat transfer, pressure drop and system performance studies are collected.
R1234ze(E) properties are well-defined and allow precise calculations.
R1234ze(E) two-phase HTC is similar to that of R134a (and higher pressure drop).
R1234ze(E) mixtures are good lower-GWP alternatives.
