Figure 7: Subcooling and superheat calculations for R-410A from the App Check & Charge. You could have doubt regarding the recommended superheat because it is not extracted from a manual. The App has the ideal superheat table loaded in its database. It is the same for all refrigerants and it is illustrated in Table 1.What should my superheat be on a 410a system? For most systems, 20F to 25F should be measured near the compressor and 10F at the evaporator. The system has 10F of superheat if the pressure is 45 psi and the temp is 32F. What should target superheat be?145 °F. 571.7 psig. 150 °F. 607.6 psig. 155 °F. 645.2 psig. You can see that this R410A pressure chart includes high and low side pressures at temperatures ranging from -60 °F to 155 °F. Higher temperature equates to higher pressure. Here are 4 examples of how you can use this chart: An R410a and R22 charging calculator or the "Non TXV Charging Guide" are required to determine the target total superheat. Because these systems do not "control superheat" it is critical that the airflow be as close to possible to correct prior to charging as the system will be charged to the airflow.(R-508B) is a better replacement than Freon™ 410A. Properties Freon™ 410A is safe to use when proper storage and handling practices are followed. It is a nonflammable, low toxicity mixture of HFC-32 and HFC-125 (50/50 wt%).
