R433b refrigerant

Feature: 1. High-efficiency, energy-saving: Refrigerant R433b have higher latent heat of evaporation than R22, and its cooling rate is better in one unit of time, its molecular weight is small so that it has excellent flow property, its lower delivery pressure reduces compressor output power and prolongs its service life. Compared with R22, it canreduce power consumption, save the operation system cost, its comprehensive energy-saving rate is high to 28%-30%. This product has passed the detection of China national testing center in Dec. 2008,tested in Gree separate air conditioner KFR-72LW/A (72520L A) A-N5. The filling weight of R22 is 1950gs, when replaced by R433b, the filling weight is just 800-850gs, can save energy 28%-30%. And R433b can play the role of lubrication too. 2. Enviromental protection: R433b won's destroy ozone layer, cause no green-house effect, safe and enviroment-friendlly, ODP=0, GWP=3. 3. Compatability: R433b has similar thermal performance to R22, has good compatability withkinds of refrigeration oil. 4. Econimical efficiency: Its filling weight is just 2/5 of R22. Properties: 1. Molecular Formula: 44.04 2. B.P.(oC): -42.3 3. Latent heat of vaporization (0oC)(kJ/Kg):305.4 , Dew point: -42.1 4. Stability: stable 5. Causticity: none 6. Explosive limit: 2.0-9.5% 7. Self-ignition point (oC):490 8. Toxicity: None 9. ODP: 0 10. GWP: 3 11. Lubricating oil: mineral oil Note: R433b is inflammable and explosive gas; should be stored in cool and draughty place; kept away from fire and heat; no mixing with oxidants; avoid naked fire.
