DuPont refrigerant R410A refrigerant R410A: is a new environmentally friendly refrigerants, does not destroy the ozone layer, the working pressure is about 1.6 times the ordinary R22 air conditioning, refrigeration higher (warmer) efficiency. Improve air conditioning performance, do not damage the ozone layer. R410A new refrigerant mixtures composed of two quasi-azeotropic made mainly of hydrogen, fluorine and carbon elements (expressed as hfc), with a stable, non-toxic, superior performance characteristics. And because no chlorine, it will not react with ozone, neither destroy the ozone layer. In addition, the introduction of new air conditioning refrigerant will also improve certain performance. R410A is by far the most internationally recognized right to replace the R22 refrigerant, and has been popular in Europe, America, Japan and other countries.
