R22 Phase Out Now Critical

R22 Phase Out Now Critical

It has been known that R22 will be phased out and Aherne Air Conditioning have been commenting on this for some time. We advised our customers that it was not necessary to change perfectly good systems as they could still be serviced and repaired using R22 thereby extending the working life of their equipment and saving our customers money during an extremely challenging climate.

However since the 1 January 2015 things have gotten a lot more serious and according to Environmental Protection Agency the following applies:

Note that although equipment containing R22 can continue to be used beyond 31 December 2014, there can be no maintenance or servicing carried out on the equipment that involves breaking into the refrigerant circuits.”

This means that we cannot fix any leak or break into the system in any way without recovering and disposing of the R22.

Drop in Replacement

In the event of a leak, we can remove any remaining R22 and dispose of it, fix the leak in the normal way and use a drop in replacement. The issue with the drop in replacement is that we do not know how it will react with the system. Once the drop in replacement is in the system, it may start to degrade components leading to further failures.

In the event of a compressor failure or inverter board, we may find it difficult to get the parts. The parts would be expensive and we would have to use the drop in replacement. Therefore the parts that we fit could be effected by the new drop in replacement and their expected lifespan would be reduced.

Taking into account the above, we would suggest that we replace an R22 system when any component fails. This would involve stripping out the existing equipment and replacing it with the new R410a system. It could take up to least 3 weeks to source and install a new system. It might be wise to buy or start planning for the replacement of your R22 system if it is in a critical environment such as a server room.  This would mean no wait time on the equipment.

It must be noted that the owner of the System is responsible for the safe disposal of R22. But by using Aherne Air Conditioning for the maintenance of your equipment you are compliant.

Ban on R22 (HCFC)

HCFCs have been used as refrigerant gases since the complete phase out of the older CFC refrigerants.  The most commonly used HCFC refrigerant is known as R22 and has been in widespread use in applications in many economic sectors. However, all HCFCs are to be completely banned after 31 December 2014.

Therefore, from 1 January 2015, the use of all R22 in the maintenance or servicing of existing refrigeration, air conditioning and heat pump equipment will be prohibited.

The restrictions on the placing on the market and use of HCFCs is set out in Article 11 of Regulation 1005/2009 on substances that deplete the ozone layer.

It should be noted that recovered refrigerant gas  is considered a hazardous waste and must be managed accordingly. From 1 January 2015, there will be no legitimate use for any recovered R22; therefore, it must be discarded and managed as a hazardous waste.

It must be noted that the owner of the System is responsible for the safe disposal of R22. But by using Aherne Air Conditioning for the maintenance of your equipment you are compliant.
