The ozone layer is a high level Chlorofluorocarbon definition is - any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC. CFCs and HCFCs were phased out due to the Chlorine that they contained. In the 1970s it was found out that the Chlorine was damaging the O-Zone layer and due to the excessive use and venting of CFCs/HCFCs into the atmosphere a hole in the O-Zone had formed. The History of CFC. Early refrigeration products from the late 19th century to the early 20th century used toxic gases like ammonia (NH3), methyl chloride (CH3CI), and sulfur dioxide (SO2). This sometimes caused fatalities from leakage of these products. This is the reason many people placed their refrigerator in the back yard.

CFC In the HVAC industry, it is known that refrigerants are essential in any air conditioner operation. Unfortunately, these refrigerants have a large impact on our environment. For 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. CFC stands for chlorofluorocarbon
The ozone layer is a high level Chlorofluorocarbon definition is - any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC. CFCs are gases that were widely used in the past in things such as aerosols and refrigerators and can cause damage to the ozone layer. CFC is an abbreviation for 'chlorofluorocarbon'.
The main difference between the two types of refrigerant is that HCFCs contain one additional hydrogen atom compared to CFCs. Chlorofluorocarbons, also known as CFCs, consist of chemical compounds made up of chlorine, fluorine and carbon. CFCs are particularly harmful when released into the atmosphere because of their destructive reaction with O-zone particles, which provide the Earth with a protective layer against UV radiation. CFCs are short for the compound, chlorofluorocarbon, which contain carbon, chlorine, and fluorine.
