Which of the following is an example of a non-fluorinated refrigerant?

• A. Freon-12
• B. Isobutane (R-600a)
• C. R-134a
• D. Ammonia (R-717)

Answer: (D)

Ammonia (R-717) is categorized as a non-fluorinated refrigerant because it is composed solely of nitrogen and hydrogen atoms, without the inclusion of fluorine. This characteristic sets it apart from the other refrigerants listed. Freon-12 and R-134a are both fluorinated refrigerants, meaning they contain one or more fluorine atoms in their chemical structure, which contributes to their global warming potential and ozone depletion potential. Isobutane (R-600a), while being a hydrocarbon and often considered more environmentally friendly compared to traditional fluorinated gases, still contains carbon atoms and, in this context, is not classified as non-fluorinated in the same way ammonia is. By identifying ammonia as a non-fluorinated refrigerant, it highlights an important distinction in refrigerant types, particularly relevant for those studying environmental impacts and regulatory protocols regarding refrigerants.
