F-Gas Compliance

IMPORTANT - Does your business use air conditioning or heat pumps?

If so, you should read the information provided below regarding the latest F-gas regulation compliance.

The air conditioning/heat pump systems that are installed within your business premises may use F-gas refrigerants in order to provide cooling and heating within the premises.

These refrigerants contribute towards global warming and regulations have been put in place to gradually reduce these gases by 2050. These systems require, by law, to be leak tested at specified intervals. More information can be found below, under leak testing.

The original F-gas regulation 842/2006 has been repealed with the new EU regulation 517/2014 on fluorinated gases. This has law came into effect 16th April 2014.

Legal requirements for all operators of stationary air conditioning/heat pumps:

  • Check if your systems contain F-gases and label them accordingly.
  • Prevent leakage and repair any leaks discovered as soon as possible.
  • Arrange correct refrigerant recovery by certified personnel during servicing and disposal.
  • Carry out leak checks at the specified intervals (see leak testing, below) only to be carried out by suitably qualified personnel.
  • Maintain records of refrigerants added/ removed, leak tests and dates of servicing.
  • Recover F-gases when disposing of equipment.

Leak Testing

Changes have been made to the limiting quantities of refrigerants which define the frequency of leak testing. The previous limits of 3,30 and 300Kg have been replaced with a number relating to the equivalent tonnes of Co2. The new labelling takes effect from 1/1/2017.

The equivalent tonnes of Co2 must be displayed on the serial label alongside the weight and type of refrigerant. To calculate the equivalent tonnes of refrigerant, the following equation is used:

Equivalent tonnes of Co2 = weight of refrigerant x global warming potential /1000, for example; a system with 5kg R410A could be calculated as ET Co2 = 5x 2088/1000 = 10.44 tonnes.

The following minimum leak test frequencies must be adhered to by law:

  • GWP less than 5 tonnes C02; - no leak test required.
  • GWP between 5 and 50 tonnes Co2; - Once every 12 months.
  • GWP between 50 and 500 tonnes Co2; - Twice every 12 months.
  • GWP more than 500 tonnes Co2; - Four times every 12 months.

The example, used above equates to 10.44 tonnes, so would require leak testing once every 12 months.

There are some exceptions to the above frequencies, which can be discussed during the survey.
