It’s Summer time, and it’s more than 80 FA outside, what would you do? …me I would turn on my air conditioner wither I was home or in my car heading to work, no one likes to be sweaty and sticky in the summer heat we all adore the fresh air that cools our bodies and make us comfortable again, well that is thanks to Freon, before 2003 the majority of the air conditioners used Freon or R22, so what is it? And why is it and the r22 freon price per pound 2017 so important?
Refrigerants, or refrigerants fluids, have a specific nomenclature to be able to differentiate them, governed by ANSI I ASHRAE Standard 34-1992 and approved by the International Union of Pure and Applied Chemistry (IUPAC). This number consists of the letter R followed by a 2 to 5-digit code that derives from its own molecular structure. And Freon is usually referred by the nomenclature R22, since Freon is a Trade name of
chlorofluorocarbons (cfcs) and not a chemical component on itself.
These are colorless, odorless, non-flammable, non-corrosive compounds in the gaseous or liquid state. Freons are not toxic on their own, but some of their decomposition products can be dangerous. The first members of this group appeared as refrigerants in the 193os. They are still used sometimes as aerosol propellants, as a raw material in the synthesis of organic compounds, as solvents, as extinguishers and as expellants in foams.
Freons are conventionally denoted Fabc, where a (number of C) – 1, b = (number of H) + 1 and c = number of F. If a is equal to 0, it is omitted from the formula. The mainly famous freons are Freon 11 (trichlorofluoromethane), Freon 22 (chlorodifluoromethane), Freon 114 (dichIorotetrafluoroethane), Freon 113 (trichlorotrifluoroethane) and Freon 12 (dichlorodifluoromethane). Because of the major roles they play in our society. They are mostly used for
Refrigerant for refrigeration installations, Refrigerant agent in air conditioning systems, blowing agent for extruded polystyrene (XPS), Component of sterilizing mixtures, and also food transportation and the big cooled warehouses, Because Freon is non-toxic, it has eliminated the danger posed by refrigerator leaks. In just a few years, compressor refrigerators that uses
Freon had become the norm for almost all domestic kitchens. In 1930, Thomas Midgley demonstrated the physical properties of Freon for the American Chemical Society by inspiring a lung full of new wonder gas and exhaling it on a candle flame that was extinguished, thus showing non-toxicity of the Freon gas. and non-flammable properties. Decades later, people realized that such chlorofluorocarbons endangered the ozone layer of the entire planet. but nowadays most developed countries are taking a banning policy toward it since it’s an CFC gas, and most uses of CFCs are now banned or severely restricted by the Montreal Protocol, if you are curious enough and you want to find out if
R22 is used in your air conditioner or in your fridge, check in the nameplate it will provide you with all the information you are willing to know, or you can always contact your manufacturer for more details. But even if your fridge or your air conditioner uses R22 you are not obliged to stop using it just because your country banned Freon, In the other hand any new manufactured cooling products should follow this policy and use new developed Refrigerants.
