The physical properties of refrigerant r410a and characteristics

r410a 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. R410A is now internationally recognized replacement for refrigerant R22 is appropriate, and in Europe and the United States, Japan and other countries. R410A, is a kind of mixed refrigerant, it is by 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, capacity, exhaust gas temperature and efficiency into consideration, tailored to synthesize a kind of refrigerant. R410A appearance not cloudy, colorless, volatile, boiling point - 51. 6 ℃, freezing point - 155℃。

r410a refrigerant main characteristics are:

( 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) Toxicity was low. Permissible concentration and R22, too, are 1000 PPM.

( 3) Don't burn. The flammability of 0 in the air.

( 4) High chemical and thermal stability of

( 5) Water solubility and R22 is almost the same.

( 6) Is mixed refrigerant, is composed 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)
