It is used where low freezing point and non-corrosive properties are important. It is used for most of the applications. Air- petroleum products alone, there are: 1. Asphalt 2.
An example of a refrigerant CFC is dichlorodifluoromethane, CF2Cl2 (also known as CFC-12), which boils at -30°C. Another once-common CFC is trichlorofluoromethane, CFCl3 (CFC-11), which boils at 24°C and was once the propellant in around half of all the aerosol cans used in the world. Why were CFCs banned? Chlorofluorocarbon (CFC), any of several organic compounds composed of carbon, fluorine, and chlorine.
They contain fluorine atoms, carbon atoms and chlorine atoms. The 5 main CFCs include CFC-11 (trichlorofluoromethane - CFCl 3 ), CFC-12 (dichloro-difluoromethane - CF 2 Cl 2 ), CFC-113 (trichloro-trifluoroethane - C 2 F 3 Cl 3 ), CFC-114 2021-4-21 · HFC-134a, also known as R-134a, for example, which is used in automobile air conditioning units, is 1430 more active than the "classic" greenhouse gas carbon dioxide (CO 2).

An example of a refrigerant CFC is dichlorodifluoromethane, CF 2 Cl 2 (also known as CFC-12), which boils at -30°C. Another once-common CFC is trichlorofluoromethane, CFCl 3 (CFC-11), which boils at 24°C and was once the propellant in around half of all the aerosol cans used in the world.
In use since the late 1920s, scientists discovered that CFCs were damaging the ozone layer of Earth's atmosphere, and their usage as propellants in aerosol sprays and coolants in refrigerators began to be phased out in the 1980s. Se hela listan på worldatlas.com Chlorofluorocarbons: CFC-11, CFC-12, CFC-113, HCFC-21, HCFC-31, HCFC-133a Evaluation of health hazards and proposals of a health based quality criterion for air and groundwater Bredsdorff, Lea; Nielsen, Else Publication date: 2014 Document Version Publisher's PDF, also known as Version of record Link back to DTU Orbit Citation (APA): HFCs, CFCs and HFCs are a subset of a larger group of climate changing gases called greenhouse gases (GHGs). Taken together greenhouse gases are expected to warm the planet by 2.5 to 8 degrees Fahrenheit by the end of century. HFCs, CFCs and HFCs contribute an estimated 11.5% to present-day effect of GHGs on climate and climate change.
A measure of the capability of a particular chemical to destroy ozone, measured against CFC-11 which has an ozone-depleting potential of 1. Global Warming Potential. A relative measure of the warming effect that the emission of a gas might have on the surface troposphere. It is measured as a factor relative to CO 2.
Why were CFCs banned? Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate. Hydrofluorocarbons (HFCs) also act to warm the planet.
