How to distinguish R22 and R410A refrigerant

At present, the most widely used refrigerant in the refrigeration industry is R22, but R22 is gradually replaced by r410a because of its great harm to the ozone layer. R410A has become the mainstream refrigerant now. So, what is the difference between the two? Today, the editor of Shandong Zixiang Chemical will introduce how to distinguish between R22 and R410A refrigerants. Friends who want to know will follow the editor’s introduction and take a look at the following article. Right.

The chemical name of R22 is difluoromonochloromethane, which is one of the freons and belongs to hydrochlorofluorocarbons. At present, R22 refrigerant still accounts for a large proportion in the use of air conditioners, mainly some old-fashioned air conditioners are in use. Because R22 refrigerant contains 'cl' elements, it has a huge hazard to the ozone layer, and it has been gradually phased out.

R410A is a new type of refrigerant. R410A new refrigerant is composed of two quasi-azeotropic mixtures, mainly composed of hydrogen, fluorine and carbon elements, and has the characteristics of stability, non-toxicity, and superior performance. At the same time, since it does not contain chlorine, it will not react with ozone and will not destroy the ozone layer. In addition, the performance of air conditioners using new refrigerants will also be improved to a certain extent. R410A is currently internationally recognized as a suitable refrigerant to replace R22, and it has gained popularity in Europe, America, Japan and other countries.

R410A and R22 have the following different characteristics:

1. R410A is made up of HFC-32 (R32) and HFC-125 by weight. The refrigerant mixed with 50% each is a near-azeotropic mixed refrigerant. R22 is a single substance refrigerant.

2. The operating pressure of R410A is about 50~70% higher than that of R22.

3. R410A has a higher vapor density than R22. For systems with the same capacity, the required refrigerant mass flow rate is the same. Because the gas piping is the same diameter, the steam flow rate of R410A is about 30% slower than that of R22.

Through the above analysis, I believe that everyone has a general understanding of the difference between R22 and R410 refrigerants. You can choose the relative refrigerant according to your needs. There is a demand for the agent, welcome to consult with us, we will serve you wholeheartedly.
