R-22 is the most widely used HCFC refrigerant for HVACR applications such as residential air conditioning, refrigeration and other cooling applications. Although R-22 has been a good solution for many different applications, it is classified as an HCFC and is subject to phase out according to the Montreal Protocol international treaty and the Clean Air Act in the United States.
In the USA, the Clean Air Act has met the requirements of the Montreal Protocol by limiting consumption of HCFC, including R-22, through a series of phase downs through 2030. Each step reduces R-22 consumption by reducing or eliminating R-22 in different market segments.
As part of this phase down, R-22 will not be permitted for use in new OEM HVACR equipment in 2010, reducing the R-22 demands into this sector and helping to meet the 75% reduction in ozone depleting substances.
These step-downs will continue through 2030, when R-22 will be completely phased out in the United States.
In the USA, these regulations may change in the future. Please visit www.forane-us.com
R-22 users should be aware of the need to transition to other, more sustainable HFC refrigerants meeting the application’s requirements. Check the Quick Reference Guide to help in your replacement selection.
