||The visuals, part of a thermodynamic evaluation of fluorinated ethers, ethanes, and propanes as alternative refrigerants, are a useful tool in comparing new chemicals to existing refrigerants in vapor compression cycles. They present the required suction superheat and the performance characteristics of the cycle with internal heat exchange. In looking for replacements for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), the U.S. EPA has initiated synthesis of new compounds with potential as alternative refrigerants for R11, R12, and R114. Basic thermodynamic properties have been measured recently. As a next step, this work predicts the thermodynamic character and performance of the newly synthesized fluorinated ethers, ethanes, and propanes in refrigeration systems.
