Summary
The study aims at reducing the flammability of propane, considered as an acceptable alternative to R22, while preserving its main thermodynamic properties. Research was directed towards a R290-HFC-134a mixture, considering the good properties of each of these two fluids, and the non-flammability of HFC-134a. The research highlighted the presence of a point of azeotropy for a blend composed of 45%/55%/R290/HFC-134a. Calorimetric results show thermodynamic performances at least equivalent to HCFC-22. This blend may be considered as a drop-in with a minor modification of the installation, mainly capillary length reduction by about 20%.
