Which refrigerant is a single-compound HFC with a GWP of 675?

• A. R-134a
• B. R-32
• C. R-410A
• D. R-404A

Answer: (B)

The refrigerant that is a single-compound hydrofluorocarbon (HFC) with a Global Warming Potential (GWP) of 675 is indeed R-32. R-32 is recognized for its relatively low GWP compared to many other refrigerants, as it only has one compound, making it simpler in terms of composition and potential environmental impact. R-134a, R-410A, and R-404A have higher GWPs. Specifically, R-134a has a GWP of about 1,430, R-410A has a GWP around 2,088, and R-404A has a GWP of approximately 3,922. These higher values reflect a greater potential for contributing to global warming if released into the atmosphere. R-32 not only has a lower environmental impact due to its GWP, but it also offers energy efficiency benefits, making it a popular choice in modern refrigeration systems. Overall, the identification of R-32 as having a GWP of 675 specifically aligns it with contemporary objectives in minimizing refrigerant emissions and advancing sustainability in HVAC applications.
