Refrigerant R12, also known as dichlorodifluoromethane, and R11, also known as trichlorofluoromethane, are chlorofluorocarbons (CFCs) that were commonly used as refrigerants in air conditioning and refrigeration systems. However, due to their harmful impact on the ozone layer, their production and use have been phased out under the Montreal Protocol. These refrigerants have been replaced by more environmentally friendly alternatives such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). **
