Not the long term solution, but until 31 December 2014 it is possible to use a recycled refrigerant – however it’s availability and cost could well be an issue.
Depending on the type, age and condition of equipment in some situations ‘replacement technology’ means it is possible to adapt systems to use legally permitted HFC’s or an HFC blend (drop in replacements). System efficiency and reliability needs to be considered and only qualified engineers can undertake this work.
Many R-22 units are now reasonably old and replacement through phase out is often the best way forward. The good news is that new systems using the latest inverter technologies are likely to have a significantly greater cooling capability (up to 15%) and to use far less electricity (on average approx. 50%). The payback period and the opportunity to make significant CO2 reductions can add up to a big incentive to invest (see examples above right).
We will assist you develop a corporate strategy to ensure compliance with the new Air conditioning legislation. Simply call us now and we will audit your equipment and advise on the options. These include replacement, refit or retrofit. A new air conditioning system may represent the best long term investment – in which case we will calculate likely energy savings, CO2 reductions and the payback period. We will project manage the transition to ensure the smooth integration of new systems and the safe disposal of the R-22 refrigerant.
From 1 Jan 2010 it became illegal to use virgin hydrochlorofluorocarbons (HCFCs) such as R-22 when servicing and maintaining air conditioning equipment. This is an issue for many as R-22 was the most commonly used refrigerant until about 2002. Until the 31 December 2014 temporary use of recycled/recovered R-22 is possible but availability could be limited and costs high.
From 1 January 2015 sales or use of recycled/recovered R-22 will be prohibited.
