Name one low-GWP refrigerant alternative to HFCs.

• A. R-134a
• B. R-32 (Difluoromethane)
• C. R-410A
• D. R-22

Answer: (B)

R-32, or Difluoromethane, is a recognized low-GWP (Global Warming Potential) refrigerant alternative to HFCs, particularly those that have higher environmental impacts. It has a GWP of 675, which is significantly lower than that of many HFCs. The push for utilizing low-GWP refrigerants like R-32 is part of global efforts to mitigate climate change and reduce the greenhouse gas emissions that contribute to global warming. In newer applications, R-32 is favored because it has good thermodynamic properties, making it an efficient refrigerant, and it can be used in many systems where traditional HFCs are applied. This makes R-32 a suitable choice for manufacturers and technicians aiming to comply with environmental regulations while maintaining system efficiency. Thus, it is positioned as a potential transitional refrigerant as industries move towards even lower GWP options.
