R22 is a single hydro chlorofluorocarbon or HCFC compound. It has low chlorine content, ozone depletion potential and only a modest global warming potential. – ODP = 0.05, GWP = 1700
Phase out dates for R22
1. From 1 July 2002 no more cooling only air conditioning equipment can be manufactured that uses refrigerant R22.
2. From 1 January 2004 no more heat pump equipment can be manufactured that uses refrigerant R22.
3. After 1 January 2010 no more virgin refrigerant R22 can be used in existing systems.
4. After 2015 no more recycled refrigerant R22 can be used in existing systems.
The phase out dates should not cause you concern, your system will only require additional refrigerant should a leak or major repair be required and this can be effected within current legislation until 2015.
