Just record your high side pressure, and match it to 410A on the chart and thats your saturation temp. Okay you will find the required amount of subcooling on your maufacturing plate of unit or in users manual.Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient.

Now here is my question. I have been a hvac maintenance tech for several years now and still learning. Just recently have been working on a 410a system and want to pressure test with nitrogen. It's a Icp heat pump with a hard shut off TXV. I seen a YouTube video with a tech "flowing nitrogen in the low side and reading system pressure on the high

R-290's pressure drop in the theoretical application above (4.428 PSI/coil) is 49% lower than an identical coil running R-22 and 36% lower for the same coil running R-134a, resulting in reduced wattage consumption. R-290: Cons. The main drawback of R-290 is: Flammability classificationIn this HVAC Training Video, I Show How to Check the Charge and Add R-410A Refrigerant on an Air Conditioner that is Low. I Show the Procedure for Connection...With that said, scientists say that the R-410A refrigerant has a GWP of 2,088. This means that it has an Earth-warming effect of 2,088 times more than CO2. By contrast, R-32 has a GWP value of 675. That's still high, but that also means its GWP is only a third of R-410A. Therefore, R-32 is a greener, eco-friendlier option than R410-A.This screenshot of the Ref Tools app shows the vapor line pressure of R410A at saturation at 39°F. Notice how the slider has been set to DEW point (inside the orange box). Before we even hook up our gauges/probes, we know the system operating pressures should be within +/- 10 PSI of: Liquid Pressure: 356.5 PSIG. Vapor Pressure: 116.1 PSIG

Static, both guages are 160 psig. When the unit ran, BOTH guages dropped to about 130. The high side was perhaps 2-5 higher. The amp draw at the compressor was 8.6 RLA out of a 22.1 suggest maximum on the equipment sticker. Correct 404a pressure ensures that your ice maker operates at peak efficiency, translating to lower energy bills and a longer lifespan for your machine. Incorrect pressures, on the other hand, can lead to a myriad of issues, including reduced ice production and increased wear on the system.
