Freon, specifically R-22, is no longer used in refrigerators due to its harmful environmental impact. It was discovered that Freon contributes significantly to the depletion of the ozone layer, which protects the Earth from harmful ultraviolet radiation. The ozone depletion caused by Freon and other chlorofluorocarbons (CFCs) led to global efforts to phase out these substances. As a result, the use of Freon in refrigeration systems has been discontinued in favor of more environmentally friendly alternatives that do not pose the same risks to the ozone layer.
