Abstract
Thermodynamic analysis using basic thermophysical property data was used to evaluate seven predicted fluorinated ether, ethane, and propane azeotropes: E125/RC270, E125/R134a, E143a/R134, R134a/E143a, E143a/R152a, R134/R245cb, and R245cb/R227ea. The performance of each azeotrope as a refrigerant in vapor compression cycles of different structures was evaluated solely on the basis of thermophysical properties. The results were used to rank the azeotropes among other refrigerants.
