R410A Freon Systems

Brief Refrigerant History

Since 1985 it’s been well documented that the ozone layer surrounding the earth has been diminishing. Scientific evidence suggests man-made chemicals are responsible for creating the hole in the ozone layer and that they’re likely to add to global ozone depletion. However, since highlighting that the chlorine in CFC’s attributes to the demise of the ozone layer, the ‘Montreal protocol on substances that deplete the ozone layer’ was negotiated and signed by 24 countries and the European Union in 1987. The protocol calls for all parties to scale down the use of CFC’s, halons and other man-made ODS.

R-22 Phaseout

In accordance with terms and agreement reached in the Montreal Protocol (The Montreal Protocol on Substances that Deplete the Ozone Layer) the United States Environmental Protection Agency (EPA) has mandated that production or import of R-22 along with other hydrochlorofluorocarbons (HCFCs) be phased-out in the United States. In EU and the USA, virgin R22 cannot be used for manufacture of new air conditioning or similar units from 1 January 2010. In other parts of the world the phase out date varies from country to country.

Today, all newly manufactured window unit air conditioners and central air conditioning systems in the United States come with R-410A. As an alternative to window-mounted systems, a ductless "split" system is available which also uses R-410A refrigerant.R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe and the United States.

Parts designed specifically for R-410A must be used as R-410A operates at higher pressures than other refrigerants. Thus R-410A systems require service personnel to use different tools, equipment, safety standards and techniques. Equipment manufacturers are aware of these changes and require the certification of professionals installing R-410A systems. In addition the AC&R Safety Coalition has been created to help educate professionals about R-410-A system.
