Division 3 Refrigerant

The global warming potential (GWP) for the refrigerant must not exceed GWP value > 2 000 over a 100 year period. If the refrigerant has a GWP of less than 150 then the minimum requirements of the coefficient of performance (COP) and primary energy ratio (PER) in heating mode and the energy efficiency ratio (EER) in cooling mode, as set out in criteria 1 and 2 of this Annex, shall be reduced by 15 %.

GWP values considered will be those set out in Annex 1 of Regulation (EC) No 842/2006 of the European Parliament and of the Council^f1.

Assessment and verification: The names of refrigerant/s used in the product shall be submitted with the application, along with their GWP values according to the Regulation above. The GWP values of refrigerants shall be calculated in terms of the 100-year warming potential of one kilogram of a gas relative to one kilogram of CO₂.

For fluorinated refrigerants, the GWP values shall be those published in the third assessment report (TAR) adopted by the Intergovernmental Panel on Climate Change (2001 IPCC GWP values for a 100 year period)^f2

For non-fluorinated gases, the GWP values are those published in the First IPCC assessment over a 100 year period^f3.

GWP values for mixtures of refrigerants shall be based on the formula stated in Annex I of the Regulation 842/2006.
