hydrofluorocarbons
Hydrofluorocarbons (HFCs) are a group of synthetic compounds primarily used as refrigerants in air conditioning and refrigeration systems. They are composed of hydrogen, fluorine, and carbon atoms, which makes them effective in cooling applications. HFCs were introduced as a replacement for ozone-depleting substances like chlorofluorocarbons (CFCs) and are considered less harmful to the ozone layer.
Despite their advantages, HFCs are potent greenhouse gases, contributing to global warming. As a result, international agreements, such as the Montreal Protocol, aim to phase down their use. Efforts are underway to find more environmentally friendly alternatives to HFCs, such as natural refrigerants and hydrocarbons.
