Which of the following refrigerants is being introduced to replace R-410A?

• A. R-22
• B. R-32
• C. R-134A
• D. R-404A

Answer: (B)

R-32 is being introduced as a potential replacement for R-410A due to its lower global warming potential (GWP). As environmental regulations become stricter, there is a growing emphasis on refrigerants that have less impact on climate change. R-32 has a GWP of approximately 675, which is significantly lower than that of R-410A, making it a more sustainable choice for cooling systems. In addition to its lower GWP, R-32 delivers efficient cooling performance, which makes it suitable for use in residential and commercial air conditioning systems. As a single-component refrigerant, R-32 is easier to handle and has a lower flammability risk compared to some other options, which is another reason the industry is considering it as a standard for future systems. Other refrigerants listed, such as R-22, R-134A, and R-404A, either have higher GWP values or phase-out timelines that make them unsuitable as replacements for R-410A in efforts to comply with international agreements aimed at reducing greenhouse gas emissions.
