FGas Regulation and GWP Values (May2014)
Introduction
GWP values of various refrigerants are important for a number of reasons, not least as a means of comparing their relative effect when they are released to atmosphere.
As science progresses and reviews take place the GWP values of some refrigerants have altered slightly, which has led to a number of different values being quoted. For instance the F-Gas Regulation (EC) 842/2006 referred to the 3rd IPCC assessment. The new F-Gas Regulation (EC) 517/2014 which will come into effect on 1st January 2015 will use the 4th IPCC assessment values.
New F-Gas Regulation
One of the requirements of the new regulation relates to leak check requirements which are based upon the GWP CO2 equivalent Tonnes. This means that the threshold level for leak checking different refrigerants varies dependent upon the GWP of the refrigerant that is used.
