HFC refrigerants contain which of the following? (A) A) Chlorine, fluorine \& hydrogen (B) B) Hydrogen, chlorine \& carbon (C) Q) Chlorine, fluorine \& carbon (D) D) Hydrogen, fluorine \& carbon

HFC refrigerants, or hydrofluorocarbons, primarily contain hydrogen, fluorine, and carbon. They were designed as a more environmentally friendly alternative to chlorofluorocarbons (CFCs), which were harmful to the ozone layer. With their decreased ozone depletion potential, HFCs were widely adopted in the refrigeration and air conditioning industries. Historically, the transition from CFCs to HFCs marked a significant step in global environmental efforts, particularly highlighted during the Montreal Protocol of 1987, which aimed to phase out substances that deplete the ozone layer. This shift reflects ongoing advancements in chemical technology to reduce the environmental impact of refrigerants while still providing effective cooling solutions.
