Genetron® 422D (R-422D)

A long-term non-ozone depleting replacement for R-22 in low- and medium-temperature commercial refrigeration systems. Suitable for direct expansion evaporators. Do not use in systems that employ flooded evaporators. For new equipment and retrofits.

Physical Properties

  • Saturated Liquid Density
    • 70.87 lb/ft3 at 86 °F
  • Specific Heat of Liquid
    • 0.35 Btu/lb at 86 °F
  • Molecular Weight
    • 109.9 lbm/lbmol
  • Specific Heat of Vapor
    • 0.2 Btu/lb at 86 °F and 1 Atm, at Cp
  • Critical Pressure
    • 566.22 psia

Temperature

  • Critical Temperature
    • 175.2 °F ASTM D-1321
  • Boiling Point/Range
    • -45.76 °F at 1 Atm

Safety & Environment

  • Flammable Range
    • None, %vol. in air Based on ASHRAE Standard 34 with Match Ignition

Standards & Approvals

  • ASHRAE Safety Classification
    • A1

Other

  • Other Notes
    • Lower capacity. Can replace HCFC-22 in many cases without having to change compressor lubricant. May be used with alkylbenzene, mineral oil and POE lubricants. If inadequate oil return is observed for AB addition of POE may be needed. Genetron 422D can, in most cases, be used with existing HCFC-22 thermostatic expansion valves.Larger valves may be needed in cases where the R-22 valve is near its maximum capacity.Lower discharge temperature than HCFC-22, which may extend compressor longevity.
