Hydrofluorocarbon (HFC) refrigerant gases are considered the 3rd generation of fluorinated refrigerant gases (GF). They were developed to be the more environmentally friendly definitive alternative to CFC and HCFC, since their ozone depletion potential (ODP) is zero.
HFCs are compounds formed from hydrogen, fluoride and carbon atoms. Since they do not contain chlorine, they are not considered ozone depleting substances (ODS).
HFCs are greenhouse gases (GHG) with a global warming potential (GWP) that is often superior to that of HCFCs. This means that in the future they will also be affected by new international accords, such as the Kyoto Protocol.
The main objective of the Kyoto Protocol is to reduce climate change that is caused by the greenhouse effect. In Europe, the European regulation EU 517/2014 (F-GAS), in addition to the Kigali accord from 2016, projected a phase down of the use of GEIs, such as HFCs. Individual countries have also begun to establish their own laws to penalise the use of said products by applying tariffs, depending on the GWP, as has been the case in Spain since 2014.
The most commonly used products initially were R-134a for sectors such as the automotive industry, R-404A and R-507 for refrigeration, and R-407C and R-410A for air conditioning.
Various HFC solutions, usually blends, were designed to be used as simple and direct drop-in conversions for existing equipment that used CFC or HCFC. For example:
With the aim of reducing its environmental impact, the industry has successfully designed various HFC solutions with a lower GWP, including the 4th generation of fluorinated gases, HFOs, used as pure products or in blends (HFO+HFC).
