R410a pressures at 90 degrees.

If you see a liquid line pressure that is more than 30 degrees saturation above outdoor temperature (like a 440 PSI liquid pressure on an R410a system on a 90-degree day), do not proceed until you have further addressed the possible causes of high head, regardless of what the superheat or subcool might be reading.I am wondering what the high and low pressures should be in a 3-ton 410a refrigerant AC system. The installer seemed very unsure of himself. It was 88 or 90 degrees F (and humid outside) and he ended up setting (leaving?) the pressures at 142 psi on the low side and 350 on the high side. He said something about a 200 psi difference being normal.410a ductless mini split operating pressures. I know that you should rarely put gauges on a ductless mini split, and that you should dump the charge and just weigh it in. I have heard that there are spec sheets that will give you "normal operating pressures" based on indoor and outdoor conditions. This would come in handy when servicing systems ...Refrigerant Type: R-134a, R-410a Maximum Operating Temperature: 250 °F, 121 °C Maximum Operating Pressure: 870 psi, 60 bar Minimum Burst Pressure: 4355 psi, 300 bar Vacuum Pressure Rating: 200 Microns External Leak Rate: 0.1 Ounces of Helium per Year at Operating Pressure Range Vibration Resistance: Conforms to UL1092362 posts · Joined 2009. #2 · Mar 21, 2012. 100 head= 37 degree saturation temp. 35 suction = a negative 11 saturation temp. Can't have sweat at 11 below zero F so my guess is it's not 410A in there. Kind of looks like pressure readings for 134a. Reclaim,leak check,vacuum to 500 microns then charge with fresh 410A. H.

We see that the target superheat for R-410A refrigerant in this system is 11°F. You can use the target superheat calculator above to get to this result much quicker.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.I would think we could have a thermostat that could do this: Heating mode: outside temp >65F: Run AUX only - lock out compressor (avoid high pressure) outside temp >10F and <65F: Run compressor and AUX as needed. outside temp <10F: Run AUX only - lock out compressor (avoid defrost cycling) Cooling mode: outside temp <60F: …R410A Pressure Temperature Chart (In Fahrenheit) Printable PDF Temp er atu r e (° F ): R410A P r essu r e (p si g ):-60 ° F 0. 9 psi g-55 ° F 1. 8 psi g-50 ° F 4. 3 psi g-45 ° F 7. 0 psi g-40 ° F 10. 1 psi g-35 ° F 13. 5 psi g-30 ° F 17. 2 psi g-25 ° F 21. 4 psi g-20 ° F 25. 9 psi g-18 ° F 27. 8 psi gUnfortunately not all such corners are exactly 90-degrees so the miter joint has to be adapted to fit tightly.
