What does CFC mean in relation to HVAC?

Answer 1

CFC'S or Chlorofluorocarbons are molecules which demolish the ozone layer. The ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet light) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer. UV is radiation and increases the chances of skin cancer.
CFC's - ChloroFluoroCarbons - are a class of volatile organic compounds that have been used as refrigerants, aerosol propellants, foam blowing agents, and as solvents in the electronic industry
ChloroFluroCarbon

a fluorocarbon with chlorine;

Commercially, the most important CFCs were derivatives of methane and ethane. These included trichlorofluoromethane (CFC-11), dichlorodifluoromethane (CFC-12), 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113) and 1,2-dichloro-1,1,2,2-tetrafluoroethane (CFC-114).

CFCs were first introduced in the 1930s as safe replacements for refrigerants such as sulfur dioxide, ammonia, chloroform, and carbon tetrachloride. These uses eventually resulted in large emissions of CFCs into the atmosphere.

Because of their low chemical reactivity, CFCs typically have long atmospheric residence times, and as a consequence are distributed globally. However, when CFCs reach the stratosphere they break down to release chlorine atoms. The chlorine atoms then react with stratospheric ozone, breaking it down into oxygen.

As ozone absorbs much of the sun's ultraviolet radiation, decreased stratosphere ozone levels could lead to increased ground-level ultraviolet radiation. This could adversely affect crop growth, and also lead to increases in cataracts and nonmelanoma skin cancer

CFCs are therefore now banned because they are the cause of the holes that grew in the Ozone layers over the planets polar regions.

The banning of CFCs has lead to research to identify other chemicals that can be used in the same applications but without the same environmental concerns.

Answer 2

CFC- chloro fluoro carbon. It's the gas that used to be used in refrigerators and aerosol cans. When it became clear that this gas was highly damaging to the ozone layer the countries of the world agreed, at the Montreal Treaty, to stop using it.

CFC can also stand for Congregatio Fratrum Christianorum, the Irish Christian Brothers, an order of Catholic monks that run schools.

Answer 3

CFC stands for chlorofluorocarbons, which are substances that were commonly used as refrigerants in HVAC systems. However, CFCs have been largely phased out due to their harmful impact on the ozone layer.

Answer 4

CFC's are chloroflouro carbon compounds while HCFC's are hydro chloroflouro carbon compounds .

Answer 5

Chlorofluorocarbons. (And "scientifical" isn't a word!)

Answer 6

CFC refers to the stratospheric ozone depleating molecule Chlorine Fluorine Carbon. Now outlawed, a single one of these chlorine molecules can destroy 100,000 Ozone molecules
