How to calculate R-410A subcooling? Alright, let's take a 3.5-ton 18 SEER unit, attach the gauge and thermometer. We measure that the temperature of the saturated refrigerant is 95°F (via pressure and referencing R-410A PT chart) and the thermometer tells us that the subcooled R-410A liquid temperature is 87°F. Let's calculate R-410A ...

I thought that R-410a is supposed to run at much higher pressures than R-22. R-410a saturation point at 80 psig is 21F -- which is below freezing! Which would mean that ice would form on the suction line if running at that low a pressure. Why do you think it's a bad compressor? It's an A/C / Heatpump unit. 2.5 tons Goodman unit.

Maintenance and Operation Costs. While R410A may be cheaper upfront, R454B could save you money over time.The low-pressure switch setting for a walk-in cooler is designed to protect the compressor from running under low-pressure conditions, which can lead to damage. Typically, the switch is set to cut off the compressor if the pressure drops below 20-25 psi, though this can vary based on the specific system and refrigerant used.
