Refrigerant R-12 is categorized as a CFC, or chlorofluorocarbon. CFCs are compounds that contain chlorine, fluorine, and carbon, and they have been widely used in refrigeration and air conditioning systems. R-12 specifically was commonly used as a refrigerant due to its stability and efficiency in these applications. However, due to its ozone-depleting properties, the use of R-12 has been phased out under the Montreal Protocol and replaced with more environmentally friendly alternatives.

While there are other categories for refrigerants, such as HFC (hydrofluorocarbons), HCFC (hydrochlorofluorocarbons), and HC (hydrocarbons), R-12 does not belong to those classes, making CFC the accurate designation for this refrigerant. Understanding these classifications is crucial for compliance with environmental regulations and ensuring proper handling and disposal of refrigerants to minimize harm to the ozone layer.
