In addition to R-32, what is another refrigerant intended to replace R-410A?

R-454B is another refrigerant developed to replace R-410A in various HVAC applications. R-410A has been widely used for residential and commercial air conditioning systems due to its efficiency; however, it has a high global warming potential (GWP). To address environmental concerns, refrigerants like R-454B were introduced, featuring a lower GWP while maintaining similar performance characteristics.

R-454B is a blend of R-32 and R-1234yf, providing an effective transition away from R-410A. This makes it suitable for existing systems that were designed for higher performance while being more environmentally friendly.

In contrast, the other refrigerants listed—R-24, R-1234yf, and R-502—do not represent suitable alternatives to R-410A in the same context. R-24 is a less common refrigerant and does not have the same applications. R-1234yf, while used in automotive air conditioning, is not a direct replacement for R-410A in residential or commercial systems. R-502 is an older refrigerant that has been phased out due to its high ozone depletion potential and is not used in modern systems. Therefore, R-454B stands out as the
