Whether R1234yf fluorine refrigerant alternatives? _

1234 - yf refrigerant manufacturer is tested, the eu decided by and dupont developed substitute for everything R1234yf is safe, can be within the scope of production and sales in Europe. Mercedes aspects but don't think so, but they said foreign R1234yf this material in the process of burning may produce harmful substances. Because of concerns that can produce pollution to the environment, before the car widely used refrigerants are forbidden to use in Europe. But mercedes-benz has refused to implement the decision, it also led to the French had issued short-term policy banned the sale of mercedes-benz vehicles. Mercedes also said they would be in air conditioning system in using carbon dioxide to replace R1234yf introduced by the European Union. 高频振荡器, 1234 yf refrigerant can be applied to the refrigerator, fire extinguishing agent, heat transfer medium, propellant, foaming agent, foaming agent and carrier gas medium, sterilization agent, polymer monomer, removal of grain fluid, the carrier fluid, polishing agent, replace, desiccant, power cycle working fluid, etc. Fluorine refrigerant alternatives fluorine refrigerant substitutes as a hot topic in the world, ask its ozone depletion QianZhi ( ODP) For O QianZhi (' greenhouse effect' GWP) Lower atmospheric lifetimes as short as possible. 1 generation of refrigerant chlorofluorocarbons dichlorodifluoromethane ( CCl2F2，CFC- 12) Due to the ODP in around 1 has been eliminated. As the first generation and second generation of transitional refrigerant substitutes hydrogen chlorine chlorofluorocarbons a methylene fluoride ( CHClF2，HCFC- 22) And so on, its ODP> 0, also gradually be eliminated. The second generation of refrigerant HFC say - Four fluorine ethane ( CF3CH2F, HFC - 134a) , which are widely used in automotive air conditioning, household appliances and industrial and commercial refrigeration equipment, can also be applied to the foam, fire-fighting, aerosols and cleaning, etc. But the HFC - 134 a greenhouse effect is higher, GWP = 1300) , atmospheric long service life, extensive use of will cause global warming, also has entered the countdown stage. In the future, what kind of refrigerant will be HFC - 134 a substitute of 1, 1 - Two fluorine ethane ( CH3CHF2, HFC - 152a) , natural working substance (CO2 R744) And 2,3,3,3 - Four fluorine propylene ( CF3CF = CH2,高频振荡器 1234。 ) And become a hot topic now. The HF0 - 1234 yf refrigerant can be applied to the refrigerator, fire extinguishing agent, heat transfer medium, propellant, foaming agent, foaming agent and carrier gas medium, sterilization agent, polymer monomer, removal of grain fluid, the carrier fluid, polishing agent, replace, desiccant, power cycle working fluid, etc.

Hangzhou E cool refrigeration Co.,Ltd is deemed as one of the leading provider of air conditioner capacitor products in China.

should only be created by the very best refrigerant gas companies with the training, experience and know how about what is expected of them.

The development of start capacitor suppliers air conditioner capacitor products has massive potential for expansion.
