R470

R470 is a refrigerant commonly used in air conditioning and refrigeration systems. It is a hydrofluorocarbon (HFC) with the chemical formula C4H8F2O. R470 is a blend of two refrigerants, R1234yf and R1234ze(E), in a 70/30 ratio. This blend was developed to provide a drop-in replacement for R410A, which is being phased out due to its high global warming potential (GWP). R470 has a GWP of 4, which is significantly lower than R410A's GWP of 2088. It is also non-flammable and has a low ozone depletion potential (ODP) of 0. R470 is used in various applications, including residential and commercial air conditioning systems, as well as in automotive air conditioning. Its use is regulated by the Montreal Protocol and the Kyoto Protocol, which aim to reduce the impact of refrigerants on the environment. R470 is considered a suitable alternative to R410A for systems that require a low-GWP refrigerant. However, it is important to note that the use of R470 should be handled by trained professionals to ensure safety and proper system performance.
