DRAFT COPY DATE: September 2011 Rev. 1 REFERENCE DOCUMENT NO. RD-0027-E After many years of testing and investigation, R410A is recognized as a suitable alternative refrigerant for R22 in medium and high temperature applications such as residential and light commercial air conditioning. R410A is a near azeotropic blend of hydro fluorocarbon or HFC compounds, comprising 50% of R32, 50% of R125. It has no chlorine content, no ozone depletion potential, and only a modest direct global warming potential.
