Abstract A R1234ze(E) based mixture was investigated as a promising environmental solution to enhance system performance of a transctitical organic Rankine
cycle(TORC). The main purpose of this study is to research the thermodynamic
properties of TORC system using R1234ze(E)/R134a mixtures with various mass
fraction of R1234ze(E) when recovering engine exhaust heat. R1234ze(E) was
selected due to its zero ozone depletion potential, relative lower global warming
potential and it can remedy the thermodynamic properties of traditional working
fluid R134a. Thermal analysis and optimization about expander inlet temperature
and pressure of TORC, mass fraction of R134a in R134a/R1234ze(E)… More >
