I have a friend who was having issues with his heat pump. It is a 2016 2 ton trane. When I hooked my guages up I had 115-120 suction and my head pressure was bouncing between 400-500. It was a rainy day so outside temp was just around 70°. Would this be indication of an overcharge or a bad txv?Differentiate between R454B and other refrigerants, like R22, R410a, and so on. Use it to calculate the required R454B superheat and total superheat. ... From the PT chart, we can read that the pressure of liquid R454B on a 65-degree day is 177.3 psig. Similarly, we can see that the vapor pressure of R454B on a 65-degree is 169.3 psig.What should 410A pressures be on a 75 degree day? If a new R-410A refrigerant bottle had a surrounding air temperature of 75°F, the pressure inside the bottle would be 217 PSIG. Likewise, an R-410A …Jun 24, 2020 · The picture below shows a system running on a 85°F day that had 6 ounces of R-410A added. In the picture, the manifold valve to the blue hose is closed so the blue gauge is measuring the pressure inside the running system. The vapor pressure is 118 PSIG and because it is 85°F outside, the R-410A bottle pressure is 254 PSIG.

R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there's absolutely 'no' set point pressure for 410a, r22, or anything else. ... For 410a this should be around 16-18 degrees F. For R22 ...You need at least a 50 degree IWB and 55 degree ODB at minimum to measure superheat accurately. You can block the coil to simulate your ODB target if it's too low, but be careful how much you raise the head pressure or your SH will drop to 0 degrees. Use a superheat charging chart to determine whether or not you can check the charge.R404A Pressures On A 100-Degree Day? If you check the chart above, you can see that the pressure of the liquid R404A refrigerant is 236.8 psig.
