Refrigerant overviewThe following is a quick overview of the most commonrefrigerants used in the HVACR industry. Access to moredetailed information can be obtained by erants/Pages/Refrigerants.aspxA common sense approach to servicing your systemAlong with prohibiting the production of ozone-depletingrefrigerants, the Clean Air Act also mandates the use ofcommon sense in handling refrigerants. This includesrecovering, recycling, and reclaiming, and by reducingleaks. The Clean Air Act outlines specific refrigerantcontainment and management practices for HVACmanufacturers, distributors, dealers and technicians.Source: efrigerant & Oils

R-22Often referred to by a brand name,such as Freon As of 2010, R-22 was discontinued foruse in new air conditioning systemsBy 2015, the use of R-22 must bereduced by 90% in the U.S.R-22 is a hydro-chlorofluorocarbon(HCFC) that contributes to ozone depletionRefrigerants & Oils

R-410aOften referred to by a brand name such asPuron , Suva 9100, or Genetron AZ-20 Has been approved for use in new systemsIt is a hydro-fluorocarbon (HFC) thatdoes not contribute to ozone depletionR-410A operating pressures are morethan 50% higher than R-22 and R-410Asystems require components capable ofworking at these higher pressuresR-410A has become the new standard forU.S. residential air conditioning systems andis the most common refrigerant for new lightcommercial unitary air conditioning systemsRefrigerants & Oils

R-407cOften referred to by a brand name suchas Suva 407C or Genetron 407C407C is a hydro-fluorocarbon (HFC) thatdoes not contribute to ozone depletionOf the higher temperature HFC options,407C most closely matches the operatingcharacteristics of R-22It is a high-glide refrigerant with lowerefficiency, but provides the simplest conversionfrom R-22 due to its similar pressuresRefrigerants & Oils

R-134aWidely used in many commercialair conditioning and refrigerationsystems globallyIt is a hydro-fluorocarbon (HFC) that doesnot contribute to ozone depletion; also thefirst non-ozone-depleting fluorocarbonrefrigerant to be commercializedIt is a single-component refrigerantwith no glide, featured in many largecommercial screw chillersRefrigerants & Oils

Important DatesJanuary 1, 2010: The Montreal Protocol doesnot allow manufacturers to produce new HVACsystems containing R-22.January 1, 2015: The U.S. must reduce itsconsumption of R-22 by 90%.January 1, 2020: Chemical companies willno longer be allowed to manufacture R-22to service existing systems.With the introduction of HFC refrigerants asalternatives to CFC and HCFC refrigerants, thequestion of the proper oil to use still comes up.The generally preferred oil for use with HFCs isa polyol ester (POE) that has an additive packagefor refrigeration applications. Mineral Oil (MO)is not recommended, because oil return isconsidered to be compromised.Scan here to see our approved refrigerants andlubricants for Copeland compressorsRefrigerants & Oils
