From 4 July 2009 it became a legal requirement for all businesses that install, maintain or service stationary
refrigeration, air-conditioning and/or heat pump equipment containing or designed to contain F gas refrigerants
to obtain an F gas Company Certificate. Here at PJ Refrigeration we make every effort to comply with the latest
legislations and our engineers are constantly monitored to ensure they are complying with these laws.
What are F Gases? Why control them?
Fluorinated greenhouse gases (F gases) are powerful greenhouse gases that contribute to global warming if released
into the atmosphere. Their effect can be much greater than carbon dioxide. Hydrofluorocarbons (HFCs),
Perfluorocarbons (PFCs) and Sulphur Hexafluoride (SF6) are all types of F gas. HFCs are the most common type
of F gases and are mainly used as the refrigerant in air conditioning and commercial refrigeration systems.
F gases are also used in other areas such as fire protection systems, solvents, high voltage switchgear, types of
aerosols and in certain specialised industrial processes.
R22 Phase Out, Legislation and Regulation
Chlorodifluoromethane was used as an alternative to the highly ozone-depleting CFC-11 and CFC-12, because
of its relatively low ozone depletion potential of 0.055,[1] among the lowest for chlorine-containing haloalkanes.
However, even this lower ozone depletion potential is no longer considered acceptable. It will be phased out soon
under the Montreal Protocol, to be replaced by refrigerants with zero ozone depletion potential such as propane
(R-290), and other refrigerants (even though they don't have very similar properties): R-410A (an azeotropic mixture
of difluoromethane and pentafluoroethane), R-507A, R-134a (1,1,1,2-tetrafluroethane) and R-409A.
An additional environmental concern regarding chlorodifluoromethane, as well as some of the proposed
replacements, is their global warming potential. The global warming potential of chlorodifluoromethane is 1700
(1700 times that of carbon dioxide)[2]. HFCs such as R-410A have high global warming potential, whereas that
of propane (R-290) is only 3.
The US EPA has enacted regulation which will phase out the use of HCFC-22 in the near future.
Air conditioning manufacturers will no longer be allowed to sell R22 equipment as of January 1, 2010.
In the aftermarket service business, the allocation rights for producers who manufacture R22 will be cut each year
making the remaining R22 supply potentially smaller than the service demand for the product. This could make R22
scarce in the future, and drive prices to consumers higher.
