What are some eco-friendly alternatives to R-410A, and how do they compare in terms of performance and safety?

R-32, R-454B, and R-466A are some eco-friendly alternatives to R-410A. R-32 has a lower global warming potential (GWP) than R-410A and is used in some air conditioning systems. R-454B and R-466A are hydrofluoroolefin (HFO) blends that offer low GWP and are being adopted in new equipment designs. These alternatives have similar performance characteristics to R-410A but require adjustments to system design and safety protocols due to their different thermodynamic properties.
