The abbreviation for refrigerants containing fluorine, carbon, and hydrogen is ____.

The abbreviation for refrigerants that contain fluorine, carbon, and hydrogen is HFC, which stands for Hydrofluorocarbon. HFCs are a class of compounds that are commonly used as refrigerants in air conditioning systems due to their effective thermodynamic properties. While they do not deplete the ozone layer, they can have a high global warming potential, which is an important aspect of environmental considerations in modern refrigeration practices.

Other abbreviations represent different classes of refrigerants that have distinct compositions and implications for environmental impact. For instance, HCFC stands for Hydrochlorofluorocarbon, which contains hydrogen, chlorine, fluorine, and carbon, and is being phased out due to its ozone-depleting potential. CFC stands for Chlorofluorocarbon, which contains chlorine, fluorine, and carbon, and is also known for its significant ozone depletion effects. HFAC is not a recognized standard abbreviation for refrigerants in this context. Therefore, HFC is the accurate representation for refrigerants made up of fluorine, carbon, and hydrogen.
