Phasing out R22
HVAC & Energy Library - Residential Information

As of January 2010 the standard refrigerant used in most all residential HVAC systems, R-22 (freon), will no longer be allowed to be used when manufacturing new equipment. This government mandate came to be after recognizing how this refrigerant R-22 was harmful to our planet’s ozone layer due to its properties of chlorine. Another part of this EPA mandate will include the complete phase out of all manufacturing of the R-22 refrigerant with no production or importation beginning in 2020.

A new refrigerant which does not contain chlorine is currently being manufactured and installed in many new systems. This new refrigerant is called R-410a and also goes by other trade names such as Puron and Prozone.

The cost of the old R-22 is increasing as the new R-410a becomes more and more popular but should not be outrageous for a few years. This mean its time to replace your HVAC system that you should strongly consider going with R-410a as it will be available in years to come as R-22 phases out. What it really boils down to is that if you install a new R-22 air conditioning system in the year 2008 you will only be able to get the R-22 refrigerant for your system until the year 2020 and refrigerant repairs could become very costly as the demand for R-22 decreases and the cost increases.

Background and Details:

The Montreal Protocol, an international environmental agreement, met in 1987 and established the first requirements of the worldwide phase-out of the ozone-depleting CFCs (chlorofluorocarbons). This included refrigerants such as R-22 and R-12. These requirements were later changed in 1996 to include to the phase out of CFC production in all developed nations.

Also, in 1992 an amendment to the Montreal Protocol established a schedule for the complete phase-out of all HCFCs (hydro-chlorofluorocarbons). HCFCs are substantially less damaging to the ozone layer than CFCs, but still contain ozone-destroying chlorine. The Montreal Protocol is now applied in the United States through Title VI of the Clean Air Act, which is implemented by EPA.

For over four decades the HCFC R-22 has been the refrigerant of choice for residential heat pump and air conditioning systems. R-22 when leaked into the atmosphere is reported to contribute to ozone depletion and the manufacture of R-22 results in a by-product that contributes to global warming. As the manufacturing of R-22 is phased out over the coming years to end production of HCFCs, manufacturers of residential air conditioning systems are now supplying equipment that uses the ozone-friendly refrigerant R-410a.

The R-22 propecia online Phase Out Schedule:

Since the terms established by the Montreal Protocol meetings the United States has through the EPA has agreed to the following dates which effect the manufacturing and service of residential heat pump and air conditioning systems:

January 1, 2004: The amount of all HCFCs that can be produced nationwide would be reduced by 35% by 2004. To do this goal, the U.S. stopped production of HCFC-141b, the most ozone-damaging of this class of chemicals, on January 1, 2003.

January 1, 2010: After 2010, while chemical manufacturers may still produce R-22 service companies to repair existing air conditioning equipment, manufactures will no longer be allowed to supply new equipment with this refrigerant.

January 1, 2020: Chemical manufactures will no longer be allowed to create new supplies of R-22. The only supplies of the R-22 refrigerant will be from sources which have been recovered and recycled. We can expect the cost of R-22 to hit the roof at this point in time.

How This Will Effect You:

The Clean Air Act does not allow for any refrigerants to be vented into the atmosphere while installation, service, or removal of old equipment. R-22 must be recovered and recycled (for reuse in the same system), reclaimed (reprocessed to the same purity levels as new R-22), or destroyed. After 2020, when servicing systems containing R-22 will rely strictly on recycled refrigerants. Expect the cost of R-22 to soon rise beyond the cost of R410a and then in a few short years make the cost of R-22 repairs reason to replace your system with one which uses R-410a. At this point it would be wise to strongly consider replacing your equipment with that of R-410a when faced with any major repair needs.

Refrigerant Solutions

Research has shown that R-410A is the best long-term replacement for chlorine-containing R-22 in residential and light commercial air conditioning systems. The air conditioning industry is fully committed to adopting R-410A as the refrigerant of choice in both scroll and reciprocating applications. In fact, new energy-efficiency regulations in 2006 compelled manufacturers to implement many new energy-efficient product lines incorporating R-410A. And, since R-410A systems are available now, demand for R-410A products will likely outpace demand for R-22 equipment in most new applications before the January 1, 2010 deadline.

R-410A has quickly become the refrigerant of choice for use in air conditioning applications because the refrigerant delivers higher efficiency and better Total Equivalent Warming Impact (TEWI) than other choices. TEWI is the best measure of global warming, considering not only the direct global warming impact, but also the sizable indirect Global Warming Potential (GWP) resulting from carbon dioxide, produced by fossil-fuel energy consumption.

Several characteristics of R-410A are different than R-22. R-410A naked celebrities operates at a higher pressure, but it is also more energy efficient, allows for fewer coils and less tubing, and has a reduced refrigerant charge and better cyclic performance – all of which contribute to its affordability. The next generation of Copeland Scroll ZPK5 compressors is optimized for R-410A and delivers breakthroughs in efficiency, reliability and sound. Additionally, Emerson is developing a new high-efficiency R-410A reciprocating compressor for residential air conditioning systems. The Copeland brand CP8 reciprocating compressor will be available for applications in the 1 ½- to three-ton capacity range.

The next generation of R-410A refrigerants and compressors has been established for air conditioning applications, to meet the 2010 regulation change; however, Emerson Climate Technologies will continue to work closely with refrigerant and system manufacturers, industry organizations and government agencies to ensure that state-of-the-art compressor technology is available to help reduce the overall environmental impact of our customers’ air conditioning applications.
