So if it's 85º out the saturation pressure in the system (that's been sitting off) should be 255 psi for 410a. If it's much different than that, then you would want to treat it as contaminated refrigerant when recovering. I assume 5 below would mean 80º in this example to account for the indoor coil being colder, so 236 psi. What is an R410A PT Chart? An R-410A Pressure-Temperature (PT) chart is a tool used in HVAC systems to determine the corresponding saturation temperature of the R-410A refrigerant at different pressures. This chart is essential for HVAC technicians as it helps in diagnosing and maintaining air conditioning systems.

Credit: Chemours. Those of you who were around for the shift from R-22 to R-410A will remember learning how to work with new system pressures. R-410A has much higher system pressures than R-22, but we won't see nearly as much of a difference between R-410A, R-454B, and R-32.. As you can see in the chart above, R-454B and R-410A have very similar saturation temperatures and pressures.The head pressure for 410A is typically around 130-225 PSIG, depending on the application. In cooling applications, 410A has a higher head pressure than R22, which can make it more challenging to operate and maintain.

The suction pressure and SST is normal, but 350 could be high for the head depending on the unit SEER. Residential 13 SEER equipment would be closer to 300 for an 80 degree ambient. It's about right for 10 SEER.

Because R-410A can absorb and release more heat than R-22, your air conditioning compressor can run cooler, reducing the risk of compressor burnout due to overheating. R-410A also functions at a higher pressure than R-22, so new compressors are built to withstand greater stresses, reducing the chance for cracking.

Break the vacuum on the system and supply liquid R-410A to the liquid line or receiver port. Weigh in the initial charge and ensure a proper vacuum was achieved. Adjust sensors or set points to operate the compressor continuously while charging the system. Add refrigerant to allow the discharge pressure to rise to 325-420 psig.It's a split system in a 2 br/2 bth condo in Palm Springs, CA. A/C seems to working fine. They did not replace the evap coils inside, nor the copper lines. The new compressor came uncharged and they installed R22 freon, (which they charged me $800 for.) I noticed the compressor documentation specifies use of R-410A refrigerant.R410A Pressure Enthalpy Chart. Download a PDF copy of the pressure enthalpy chart for both Metric and Imperial Units. By.
