If it dates from before 1995, it probably contains chlorofluorocarbons (CFCs - fluids R11 and R12), whose global warming potential is up to 10,000 times that of CO2. CFCs have been banned in the European Union since that date.
'Between 1995 and 2010, the mainly authorised fluids are hydrochlorofluorocarbons (HCFCs - R22 fluids), whose global warming power is up to 2000 times that of CO2.
The period 2010 - 2015 corresponds to a transition period during which the manufacture of new equipment containing HCFCs is prohibited. In 2015, the presence of HCFCs in equipment is prohibited.
If built after 2015, it may contain :
hydrofluorocarbons (HFCs - R134a) whose warming potential is 1,500 times that of CO2. These fluids will be banned in new equipment from 1 January 2022.
Hydrocarbons such as isobutane (R600) and propane (R290). Their contribution to greenhouse gases corresponds to 3 times that of CO2. There is no legal restriction on their point source release into the atmosphere.
Other fluids are being tested, such as CO2 or ammonia (NH3).
