Freon is the registered name for a number of products containing halocarbons. These refrigerants undergo a process where it condenses into a liquid and evaporates into a solid, losing a substantial amount of heat in the process. Once it's cold enough, the gas is channeled through coils that allow it to absorb heat from the air in the fridge.
