Saving the Ozone with R-410A

Protection of the earth’s ozone layer is, in the heat of the summer especially, a concern often on the minds of people today. Ozone-unfriendly chemicals and aerosols have been used for years without the knowledge of the damage they caused, ripping holes in the ozone and exposing us to harmful, unbuffered sunlight.

But now we know better. Today, many people want to know what they can do to lessen the impact that the chemicals and aerosols we use down here are having on the protective layer keeping out the full effect of the sun’s deadly rays.

In an effort to help prevent the continued depletion of the ozone layer, the United States Environmental Protection Agency ordered as of Jan. 1, 2010 the phase-out of the use of R-22 and other hydro fluorocarbons in the construction of new air conditioning units. All new air conditioning systems in the U.S. now use ozone-friendly R-410A as their refrigerant.

R-410A, a mixture of difluoromethane and pentafluoroethane more commonly known as Puron, was created in 1991 by Allied Signal – now Honeywell — and has been shown not to deplete the ozone layer like its predecessor refrigerants. R-410A has been brought to the commercial air conditioning market thanks to a team effort of Carrier Corporation, Emerson Climate technologies, Copeland Scroll Compressors, and Allied Signal. Carrier debuted the R-410A residential AC unit in 1996 and has the trademark to the name Puron.

Because R-410A is unique in that it uses higher pressures to operate, any R-410A-based systems need equipment and safety considerations specific to that difference. Only R-410A-qualified personnel should work on these systems.
