Comparative analysis of the characteristics of R410A and R32.
1. Thermophysical properties: R32 charging volume can be reduced, 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 requirement of R410A system, and R32 system exhausts Compared with R410A, the temperature rises up to 35.3℃.
2. Environmental protection characteristics: ODP value (ozone depletion potential value) is 0, but R32's GWP value (global warming potential value) is moderate, compared with R22, the CO2 emission reduction ratio can reach 77.6%, while R410A is only 2.5% , It is significantly better than R410A in terms of CO2 emission reduction.
3. Safety: Both R32 and R410A are non-toxic, while R32 is combustible. Among several alternatives to R22, R32 and R290, R32 has the highest lower combustion limit, LFL. Although R290 is the most environmentally friendly, it is highly flammable and has a safety level of A3. Therefore, it is required to only charge air conditioners within 2p, and large number air conditioners are restricted.
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 also show that the refrigeration system using R32 has a slightly higher energy efficiency ratio than R410A .
