I see you have some very interesting articles. I read the one on energy and exergy analysis of refrigeration systems using low GWPRs when you first posted it. I have provided the cycle analysis for several geothermal plants operating with an organic Rankine cycle and performance tested several such systems. I have also provided thermodynamic properties for various substances including NOVEC. I would like to see some graduate students interested in this subject.

I am currently studying thermoelectric devices, particularly the application of non-equilibrium thermodynamics in performance optimisation. Eager to connect with you!

Thanks
