Question

information on hydro fluorocarbons

Answer 1

HFCs are a group of man-made chemicals containing the elements carbon, hydrogen and fluorine. They are colourless, odourless and unreactive gases.

HFCs are mainly used in refrigeration and air conditioning equipment and as propellants in industrial aerosols (replacing the formerly used CFCs and HCFCs which have been shown to damage the ozone layer in the upper atmosphere). HFCs are also used for foam blowing, solvent cleaning and in fire extinguishers.
The main sources of HFCs are from the manufacture of, leakage from and end of life disposal of refrigeration and air conditioning equipment and aerosols. HFCs are entirely man-made - there are no natural sources.
