制冷剂R417a

R-417A is a cost-effective, non-ozone-depleting HFC retrofit refrigerant for R-22 in direct expansion stationary air conditioning and medium-temperature commercial refrigeration systems. Replaces R-22 Applications Residentialand commercial AC systems Medium-temperature commercial refrigeration, including: -food service -supermarket display cases -food storage and processingBenefits Provides efficient, cost-effective retrofits Non-ozone-depleting HFC In most cases no change of lubricant type during retrofit is required--compatible with traditional and new lubricants Enables continued use of existing equipment Can be topped off during service without removing the entire refrigerant charge Performance Significantly lower discharge temperature and pressure vs. R-22; likely to prolong the life of the compressor In most systems provides required cooling capacity Has been shown to offer energy savings in some systemsPhysical properties: Component Chemical name Molecular formula Weight% HFC-134a 1,1,1,2-Tetrafluorethane CH2FCF3 50% HFC-125 Pentafluoroethane CHF2CF3 46.6% R600 Butane C4H10 3.4% Molecular weight Boiling point Critical temperature Critical pressure Odor Form Color Heat of vaporization at boiling point Vapor Pressure at 25 Vapor Density at 25 (Air = 1) Liquid Density at 25 Ozone Depletion Potential(ODP) Global Warming Potential(GWP) 100yr ASHARE Safety Group Classification Flammability at 1 atm. and 18 106.7 -39 89.9 4240kPa Slight ethereal Liquefied gas Clear, colorless 203.4KJ/kg 985.95kPa 3.75 1.150g/cm3 0 2200 A1/A1 Non-flammable Lubricant Recommendation R417A is compatible with traditional and new lubricants--mineral oil (MO), alkylbenzene (AB), and polyol ester (POE)--in most cases, no change of lubricant type during retrofit is required.
