It was then that the first warnings of damage to the stratospheric ozone were published. It was in the late 1970s when researchers and scientists have been working on alternatives for CFCs in refrigerants. These then react with the ozone molecules and in turn gets depleted. In the stratosphere, the molecules of CFC break down due to the action of solar ultraviolet radiation and release the chlorine atoms. The ozone shields living organisms on Earth from Sun’s ultraviolet radiation. Studies have shown that CFCs that are released into the atmosphere are accumulated in the stratosphere, where they cause deteriorating effects on the ozone layer. One of the elements that make up CFCs is chlorine.Ĭhlorine exists in the atmosphere naturally, but in very small amounts and it so happens that CFCs are a way of introducing this into the ozone layer. The use of these family of compounds has grown exponentially over the years. They have also been used for foamed plastics like expanded polysterene or polyurethane foam for insulation products. The most common representative of this is dichlorodifluoromethane (R-12 or Freon-12)ĬFCs were developed back in the 1930’s as a safe, non-toxic, non-flammable alternative to different dangerous substances such as ammonia which is used in refrigeration and spray can propellants. They are known around the world as Algofrene, Arcton, Asahiflon, Daiflon, Eskimo, FCC, Flon, Flugene, Forane, Freon, Fridohna, Frigen, Frigedohn, Genetron, Isceon, Isotron, Kaiser, Kaltron, Khladon, Ledon, Racon and Ucon. Buy nowĬFC’s and its related compounds are known by different names. World’s 1st Portable Air Conditioner 12 volt compresser. It has a common subclass called hydrochlorofluorocarbons (HCFCs) which contains hydrogen. It is an organic compound that contains carbon, chlorine and fluorine, which is produced as a volatile derivative of methane and ethane. Unfortunately, these refrigerants have a large impact on our environment.įor decades, CFCs have already been known to deplete ozone and are also to blame for global warming. To be able to understand CFCs further, let’s start by learning what it really is.ĬFC stands for chlorofluorocarbon. In the HVAC industry, it is known that refrigerants are essential in any air conditioner operation.
