Halocarbons

Organic compounds containing carbon atoms and one or more of the halogens chlorine (Cl) fluorine (F) bromine (Br) or iodine (I).

Halogens

Family of elements that possess similar chemical properties. Particularly fluorine, chlorine, bromine, iodine and astatine.

HCFC

Hydrochlorofluorocarbons are chemical compounds made of hydrogen, chlorine, fluorine and carbon atoms.

HFC

Hydrofluorocarbons are chemical compounds made of hydrogen, fluorine and carbon atoms

HFO

Hydrofluoroolefins (HFOs) are unsaturated organic compounds composed of hydrogen, fluorine and carbon. HFO refrigerants are categorised as having zero ODP (Ozone Depletion Potential) and low GWP and so offer a more environmentally friendly alternative to CFCs, HCFCs and HFCs. HFOs are being developed as "fourth generation" refrigerants with 0.1% of the global-warming potential of HFCs.

HVAC&R

Heating, ventilation, air conditioning and refrigeration
