Experimental assessment of R134a and its lower GWP alternative R513A [PDF]
Lower GWP refrigerants are essential to mitigate the impact of refrigeration systems on climate change. HFO/HFC mixtures are currently considered to replace HFCs in refrigeration and air conditioning systems.

Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...

Exergy analysis of organic Rankine cycle for waste heat recovery using low GWP refrigerants
The use of exergy analysis in thermodynamic systems, as well as energy analysis, is quickly increasing. Exergy analysis is useful for identifying processes that cause exergy destruction and losses, and it may be used in conjunction with energy analysis ...
