Comparison of Refrigerant R410a,R22 and R407c

R407c

From the mid-1990s, people began to choose R407C (HCF refrigerant) as a substitute for R22. R407C has the same operating pressure and temperature as R22. R407C has zero ozone depletion potential and very low global warming potential. In many cases, only a slight improvement to the R22 system can be used as a substitute. Has been widely recognized in the European market. However, due to the significant temperature drift of the R407C system during high-pressure exhaust, it is difficult to achieve the efficiency that matches the R22 system. Therefore, Japanese air-conditioning manufacturers produce a large number of R407C products for export to Europe on the one hand, and on the other hand to Japan The recognition of R407C is very low. 

R410a

Instead, it is replaced by another R410A refrigerant that also belongs to the HCF category. In the United States, although the replacement of R22 refrigerant is relatively clear, R407C refrigerant has never been favored by the air-conditioning manufacturing industry, and the selected alternative is also R410A. 

Even in Europe, where R22 refrigerant was eliminated earlier, after using R407C refrigerant for several years, it finally began to transform to R410A. 

To be sure, R410A refrigerant is the best choice to replace R22 refrigerant worldwide. Although its advantages and disadvantages are mixed, the unique advantages of R410A are more attractive than R134a and R407C. It is expected that R410A refrigerant will gradually become the mainstream refrigerant for air-conditioning equipment.
