IIR documentSummary
The authors conclude that CO2 is not a direct natural substitute for R-410A and that a single component direct substitute with a global warming potential (GWP) of less than 150 does not exist. However, by using neural networks to predict binary azeotropes, they have been able to identify nine potentially azeotropic or near-azeotropic substitutes for R-410A, all formed from natural refrigerants or synthetic chemicals with a GWP less than 150. These are currently undergoing practical testing.
