[Refrigerant] What is the difference between R22 refrigerant and R410A refrigerant

R22 refrigerant and R410A refrigerant are the blood of the air conditioner. Without refrigerant, the air conditioner cannot operate normally; without refrigerant, the air conditioner seems to be sick; too much refrigerant will seriously affect the effect of the air conditioner. At present, the most widely used refrigerants are R22 refrigerant and r410a refrigerant. Are there many essential differences between R22 refrigerant and R410A refrigerant? The following editor of Seganet will take everyone to learn more about R22 refrigerant and R410A refrigerant.

What is the difference between R22 refrigerant and R410A refrigerant-what is R22 refrigerant

R22 refrigerant is one of the most widely used refrigerants before 1. The chemical name of R22 refrigerant is difluoromonochloromethane, which belongs to the category of hydrochlorofluorocarbons. Because R22 refrigerant is very harmful to the ozone layer, the Montreal Protocol stipulates that it will be completely phased out before 2020. Now many manufacturers have stopped producing air conditioners using R22 refrigerant.

What is the difference between R22 refrigerant and R410A refrigerant-what is R410A refrigerant

R410A refrigerant is currently recognized as the world’s best alternative to R22 The most suitable and environmentally friendly refrigerant has been popularized in Europe, America, Japan, my country and other countries. R410A refrigerant is a new type of refrigerant. R410A refrigerant is composed of two quasi-azeotropic mixtures, mainly composed of hydrogen, fluorine and carbon elements. R410A refrigerant has the characteristics of stability, non-toxicity and superior performance. Since R410A refrigerant does not contain chlorine, it will not destroy the ozone layer. And the air conditioning performance using R410A refrigerant will be better.

What is the difference between R22 refrigerant and R410A refrigerant-comparison of their characteristics

1. R22 refrigerant is a single substance refrigerant; R410A refrigerant is It is a mixture of two different substances, HFC-32 (R32) and HFC-125.

2. R410A refrigerant has a higher vapor density than R22 refrigerant. For systems of the same capacity, the required refrigerant mass flow rate is the same. If the gas piping of the same pipe diameter is used, the vapor flow rate of R410A refrigerant is about 30% slower than that of R22 refrigerant.

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

Through the above introduction and analysis, we can see that R410A refrigerant is of low toxicity and does not burn; there is also R410A refrigerant that does not destroy the ozone layer, while R22 refrigerant The ozone layer destruction coefficient of R410A is 0.05; the total heat transfer characteristics of R410A refrigerant system are better than those of R22 refrigerant, which can improve the system efficiency and reduce the heat transfer area of u200bu200bthe heat exchanger. These advantages of R410A refrigerant are also why R410A refrigerant can replace R22 refrigerant as the most widely used refrigerant at present.
