Refrigerant is the central air-conditioning refrigeration cycle of the working medium, refrigerant by evaporation in the evaporator, condensation in the condenser heat transfer cycle to achieve the purpose of refrigeration. Freon is currently widely used refrigerant, it is a wide variety, in order to avoid writing its molecular-style troubles, also to facilitate memory, people have formulated a set of simplified code to represent various freon coolant, such as R12, R22, R410A and so on. Now the central air-conditioning is commonly used R22 and R410A two different refrigerant. But consumers do not know the difference between the two refrigerants, and do not have any kind of refrigerant. The following small series with you to learn about these two kinds of refrigerant.
What is R22 and R410A
R22 's chemical name is two fluoride, a member of Freon family, belonging to HCFCs. Most of the refrigerants we are using are R22. As the refrigerant is harmful to the ozone layer, the Montreal Agreement stipulates that it will be eliminated by 2020.
R410A is a new type of refrigerant. R410A new refrigerant from two quasi-azeotropic mixture, mainly hydrogen, fluorine and carbon elements, has a stable, non-toxic, superior performance and other characteristics. At the same time, because of non-chlorine element, it will not react with ozone, that is, the ozone layer will not destroy. In addition, the use of new refrigerant air-conditioning in performance will have a certain increase. R410A is so far internationally recognized as a substitute for R22 's most suitable refrigerant, and in Europe and America, Japan and other countries get popularity.
R410A new refrigerant is not only environmentally friendly, but also improves air-conditioning performance
