2.6 Handling of refrigerant
The following information summarises the requirements and guidelines for hand-
ling the refrigerant used in cooling units. For further information, see the F-gas
Regulation (EU/517/2014 on fluorinated greenhouse gases) and the Swedish
Refrigerant Regulation (SFS 2016:1128). The purpose of the regulations is to
contribute to achieving EU goals for reduced climate impact in accordance with
the Kyoto Protocol.
Operator responsibilities
By operator, we refer to the European Parliament’s definition: “...the natural or
legal person exercising actual power over the technical functioning of the equip-
ment and systems...”.
Generally speaking, the unit operator must:
• Minimise and prevent leakage
• Take corrective action to remedy any leakage that arises
• Ensure that leak inspection, service and repair of the refrigerant circuit are
carried out by a certified refrigeration technician
• Ensure that refrigerant is handled in an environmentally secure manner and in
accordance with national regulations.
The levels for the various actions to be taken for a system are calculated using
carbon dioxide equivalents, CO2e (tonnes). This figure is calculated by multiply-
ing the refrigerant’s GWP value (Global Warming Potential) by the filling amount
in kilos. GWP for R410a is 2088. A filling amount of 1.1 kg R410A therefore cor-
responds to (1.1×2088)/1000 = 2.30 CO2e(tonnes).
The unit is marked with refrigerant quantity and carbon dioxide equivalent.
