R-32 along with R-125 gets you that R-410A that is found in nearly every air conditioner today. However, in recent years there has been a push to slowly phase down R-410A. That is because of 410A’s very high Global Warming Potential, or GWP.Check Details R454b pressure enthalpy chart.

Oct 13, 2023 · You need to make several modifications to the R410A system if you want to replace it with R454B. Hence, R454B is not a drop-in placement for R410A. Here are some of the reasons why this is the case: R410A operates at higher pressures than R454B. This makes the compressor and the condenser less able to work with a low pressure refrigerantFigures 6 and 7 shows the variation of pressure, volume fraction and temperature for the fluids R454B and R161 for a capillary inlet temperature of 40 °C (after 10 K sub cooling), respectively. It can be noted that inlet pressure of expansion capillary is high for R1123 when compared to R454B and R161.Mid-size, medium temperature systems 2 to 40 kW: R454C, R455C and R1234yf Smaller systems below 2 kW : R290 (A3 class) Can I use A2L refrigerants in retrofit applications?…
