Which Is Better, Refrigerant Gas R32 or R410, And What Is The Difference?2020-10-29
R32 is energy-saving, green, and does not harm the ozone layer. It is also the new star of modern refrigerants, and it is an important part of replacing R22. Refrigerants R32 and R410 are products that are widely used to replace R22 refrigerant. The difference between the two is:
1. Thermal properties
The R32 charge can be reduced, which is only 0.71 times that of R410A. The working pressure of R32 system is higher than R410A, but the maximum increase is not more than 2.6%, which is equivalent to the pressure requirements of R410A system. At the same time, the exhaust temperature of R32 system increases the most compared to R410A. Up to 35.3℃, the existing compressor needs to be redesigned.
2. Environmental protection features
The ODP value is 0, but the GWP value of R32 is moderate. Compared with R22, the CO2 emission reduction ratio can reach 77.6%, while R410A is only 2.5%, which is significantly better than R410A in terms of CO2 emission reduction.
