Environmental protection refrigerants, what is a R410A and R22 refrigerant of the difference

Is a kind of new environmental protection refrigerant R410A refrigerant, not damage the ozone layer, refrigerant is more efficient than others. New refrigerant composed of two kinds of quasi azeotropic mixture, mainly include hydrogen, fluorine and carbon ( Said for HFC) , has the stability, non-toxic, superior performance, etc. At the same time as a result of not containing chlorine, so will not react with ozone, can neither destroy ozone. In addition, the adoption of new refrigerant air conditioning again in terms of performance will be improved. Environmental refrigerant r410a is by far the most appropriate internationally recognized to replace R22 of refrigerant, and in Europe and the United States, Japan and other countries. Environmental refrigerant R410A is mixed refrigerant: R410A, is a kind of mixed refrigerant, it is by the R32 ( Methylene fluoride) And R125 ( Five fluorine ethane) Consisting of a mixture, its advantage is that can be used according to the specific requirements, for a variety of properties, such as flammability, colorless appearance, not cloudy, volatile, boiling point - 51. 6 ℃, freezing point - 155℃； So its all aspects of the chemical composition and value are basically met the requirements of all kinds of machines. : the difference between the environmental refrigerant R410A and R22 refrigerant R22 as refrigerant has to metal has good stability, non-corrosive characteristics, but chlorine refrigerant cause earth's ozone layer, humans began to look for alternative refrigerant R22 environmental protection and have everything, R407C, R410A. R410A is gradually into the mainstream. The difference between the other and R22 refrigerant; ( 1) Does not destroy the ozone layer. Its molecular formula does not contain chlorine, therefore its ozone depletion ozeme depletion potential ( ODP) To zero. Global warming ozeme depletion potential ( GWP) Less than zero. 2. ( 2) Very low toxicity. Permissible concentration and R22, too, are 1000 PPM. ( 3) Don't burn. The flammable in air polarity is 0. ( 4) High chemical and thermal stability. ( 5) Water solubility and R22 is almost the same. ( 6) Is mixed refrigerants, consists of two kinds of refrigerants. ( 7) Not with mineral oil or alkyl benzene oil miscibility. ( With POE [ Ester lubricants] ,通过 Ether lubricating oil] Miscibility) 。
