Introduction of R410a Refrigerant

Currently, only r410a and R32 refrigerants are used in home improvement air conditioners to replace R22 refrigerants. Today's editor of r410a refrigerants conducts a simple comparison and analysis on the characteristics of R22, R410a and R32 air-conditioning refrigerants.

1. Thermal properties: R32 refrigerant 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 increase does not exceed 2.6 %, which is equivalent to the pressure requirements of the R410A system, and the exhaust temperature of the R32 system is up to 35.3℃ higher than that of the R410A.

2. Environmental protection characteristics: ODP value (ozone depletion potential) is 0, but R32 has moderate GWP (global warming potential), compared with R22 CO2 The 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.

3. Safety: R32 refrigerant and R410a refrigerant are non-toxic, while R32 is flammable, but in several alternatives to R22, R32, R290, R161, R1234YF , R32's lower combustion limit LFL (lower ignition limit) is high. For these refrigerants, R32 is not easy to burn.

4. Cycle performance: In terms of theoretical cycle performance, the cooling capacity of the R32 system is 12.6% higher than that of R410a, the power consumption increases by 8.1%, and the overall energy saving is 4.3%. The experimental results are also It shows that the energy efficiency ratio of the refrigeration system using R32 is slightly higher than that of R410a.
