英力士（原ICI）制冷劑 INEOS KLEA Series RefrigerantsKLEA 134aKLEA 410AKLEA 407CKLEA 404ARefrigerants - KLEA 134a (R134a制冷劑)Widely accepted as the most appropriate alternative for R-12 over the majority of the application range for both retrofit and new equipment. A very good match to R-12 for air conditioning, high and medium temperature usage. Some low temperature (-20C to -30C) R-12 applications may benefit from the use of an HFC blend from the R407-series such as R-407D, an R-500 and low-temperature R-12 alternative.Please note that not all products are available in all markets.Refrigerant - Klea134a Physical PropertiesPropertyUnitsValueMolecular Weight-102.03Boiling Point℃ @ 1 atm-26.074Melting Point℃-103Critical Temparature℃101.03Critical Pressurebar40.56Critical Densitykg/m3508Vapour Pressure(25℃) bar6.652Latent Heat of Vaporisation at nBptkJ/kg216.77Saturated Vapour Density at nBptkg/m35.229Coeff.

R-407C has been formulated as a good match to the existing HCFC refrigerant R-22 for use in air conditioning, chilling and refrigeration applications and is the first of the R-22 alternatives to be used on a commercial scale. Suitable for retrofit and original equipment usage.Composition ( wt% ) R-32/R-125/R-134a = 23/25/52Please note that not all products are available in all markets.Refrigerants - Klea407C Physical PropertiesPropertyUnitsValueBubble Point℃-44.0Dew Point℃-36.8Bubble Point Pressure (25℃)bara11.9Estimated Critical Temparature℃86Latent Heat Vaporisation (25℃)kJ/kg193.9Trouton"s ConstantkJ/kg.K1.08Coeff.
