Which of the following refrigerants is primarily classified as HFC?

The correct answer is R-410A, which is primarily classified as a hydrofluorocarbon (HFC). HFCs are a group of synthetic refrigerants that have been developed as alternatives to ozone-depleting substances used in refrigerants, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). R-410A specifically contains no chlorine, making it an environmentally friendly option in comparison to older refrigerants.

R-410A is a mixture of two HFCs, namely R-32 and R-125, which contribute to its efficiency and performance in cooling systems. This refrigerant is widely used in air conditioning applications due to its favorable thermodynamic properties and low environmental impact, aligning with regulations that seek to reduce greenhouse gas emissions.

On the other hand, R-12 is a CFC that has been phased out due to its high ozone depletion potential. R-22 is classified as an HCFC, which also has a negative impact on the ozone layer and is being phased out alongside R-12. R-500 is a blend of R-12 and R-152a, which includes CFCs and is not classified as an HFC
