No, modern refrigerators do not use Freon as a refrigerant. Instead, they use more environmentally friendly refrigerants such as HFCs or HFOs.
Refrigerators now primarily use hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs) as refrigerants instead of chlorofluorocarbons (CFCs). These alternatives have lower ozone depletion potential and are less harmful to the environment. Some newer refrigerators also use natural refrigerants like carbon dioxide or propane.
People use CFC's. They react with ozone and deplete it.
