R22 Phase Out Now Critical – Free R22 Replacement Survey for your Building
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.
R22 is an Ozone Depleting Substance (ODS) according to the EPA . R22 units are those air conditioning systems which use the refrigerant R22 to pump the heat from inside a building to outside and vice versa. Ozone-Depleting Substances (ODS) are chemicals that can damage the earth’s ozone layer if they escape into the upper atmosphere. ODS include hydrochlorofluorocarbons (HCFCs), which are still in use as refrigerants.
The only ODS still widely in use are HCFC refrigerants, especially R22 and blends such as R408A. The use of virgin HCFCs in maintenance and servicing of refrigeration and air-conditioning equipment is banned since the end of 2009. Recycled and reclaimed HCFCs could continue to be used until the end of 2014.
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. There is replace technology available with Mitsubishi Electric as discussed previously. This has the advantage of using the existing pipe work. The problem with R22 being phased out is that if the equipment develops a leak then it is impossible to replace the refrigerant.
An option that can exist is to use a drop in replacement which is a refrigerant that has been blended to act similar to R22 in terms of performance. However it will not be as efficient and it needs to be tested in each application first. Therefore the preferred option is to change out the unit in favour of a non ODS refrigerant such as R410a.
