What type of refrigerant is R-410A?

R-410A is classified as a high-GWP synthetic refrigerant. Specifically, it is a blend of two hydrofluorocarbons (HFCs), which contributes to its high Global Warming Potential (GWP). The GWP of R-410A is significantly higher than that of many natural refrigerants, making it a less environmentally friendly option in terms of greenhouse gas emissions.

The term "synthetic" indicates that R-410A is manufactured through chemical processes, rather than being derived from natural sources. This distinction is important because natural refrigerants typically include substances that occur in nature, such as hydrocarbons, ammonia, and carbon dioxide, which tend to have lower or negligible GWPs compared to many synthetic options.

While R-410A is indeed a fluorinated refrigerant and falls under the category of HFCs, the designation as high-GWP synthetic primarily reflects its environmental impact and chemical nature. This makes choice B the most accurate description of R-410A’s classification.
