WebN. A. : HFO (Hydrofluoro-Olefines) are a class of unsaturated molecules that contain at least one carbon-carbon double bond. These molecules are highly reactive in the atmosphere, and consequently have a relatively short lifespan. This short lifespan partially contributes to the low GWP of these new fluids. Web16 jan. 2024 · The widely used hydrochlorofluorocarbons (HCFCs) are being phased out due to the ozone depletion potential (ODP), while the hydrofluorocarbons (HFCs) are required to be phased down from as early as 2024 due to the global warming potential (GWP) according to the amendment to Montreal Protocol. 1 Since 2011, the refrigerants …

Hydrofluorocarbons (HFCs) are man-made organic compounds that contain fluorine and hydrogen atoms, and are the most common type of organofluorine compounds. Most are gases at room temperature and pressure.
