F-Gas Rules & Regulations

The following document contains guidance on the future use of R404A and the new F-Gas regulations.

The new F-Gas regulations which came into force on 1st January 2015 place restrictions on the use of certain HFC refrigerants in certain applications. R404A has a GWP of 3922 and is therefore in the group of refrigerants with a GWP > 2500 which will be most affected by the new regulations.

The key parts of the regulation that will have a major impact on the use of R404A are the following;

F-Gas Regulation

Future Availability of R404A

The phase down of HFC refrigerant has been derived from a baseline of HFCs placed on the market in 2009 – 2012 in CO2 equivalent tonnes calculated from the GWP of the various refrigerants.

In 2016 and 2018 the quantities allowed to be placed on the market are reduced by 7% and 37% from the baseline.

Furthermore in 2017 pre-charged equipment from outside the EU must be included within the quota for the first time, which may account for as much as 10% of use. This part of the regulation does not ban any refrigerant but the total amount placed on the market in a year must remain within the maximum allowed. Those allocated quota to place on the market are limited to supply a total amount of CO2 eq Tonnes, but are able to decide what product mix they wish to supply. In simplistic terms this means it is possible to supply larger quantities of lower GWP refrigerants than higher GWP refrigerants such as R404A.

It is not known precisely what effect the reductions in quota will have on the supply of R404A in 2016, 2017, and 2018, except that the overall use of high GWP refrigerants such as R404A will need to reduce significantly during that period and cannot continue at current levels.

This can be achieved by a number of measures, better leak prevention and detection, a move away from the use of R404A in new equipment to lower GWP refrigerants and conversion of existing systems. The speed at which this happens will determine the effect the phase down will have on those still needing to buy R404A in 2017 and 2018.

Should you be using R404A in New Equipment?

Anyone installing equipment with R404A now will probably have to retrofit to a lower GWP refrigerant in the next few years, this is likely to be before the end of the natural working life of the system. You should consider carefully therefore whether it makes economic sense to use R404A in new equipment and strongly consider equipment that uses lower GWP alternatives.

What other Refrigerants have a GWP over 2500?

Whilst this guidance note relates to R404A, as it is the most prevalent gas used in refrigeration applications, most of the comments also apply to all refrigerants with a GWP > 2500. These are R507, R422A, R434A and R428A.

What should end users or suppliers do now?

‘ACRIB’ advises that you seek the views of the equipment manufacturers, refrigerant producers and suppliers about the effect quotas may have on their ability to supply R404A in future and the suitability of lower GWP alternatives available for the application in question.
