HFC refrigerant (hydrofluorocarbons) is a greener alternative to CFC and HCFC, which mainly includes R134A, R125, R32, R407C, R410A, R152, etc. Although climate warming potential value is high, ODP (Ozone Depleting Potential) is zero. In the “Montreal Protocol,” there is no time limit for its use, and it is defined as a greenhouse gas in the Kyoto Protocol of the “United Nations Framework Convention on Climate Change”.
All the refrigerants we currently use are all Freon products, and non-Freon refrigerants have not been developed so far. Governments expressly banned the first category of chlorofluorocarbon products (CFC). For hydrochlorofluorocarbon products and hydrofluorocarbon refrigerants, there is still a long period of use.
