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 PSIGThis prompted the discovery and distribution of R-410A, also known as Puron. R-410A is a fraction as damaging to the environment as R-22, and it's just as powerful for cooling. This is the reasoning behind most air conditioners running with this type of refrigerant—it's just better than the old kind in almost every way! "Is It DangerousOn quite a few systems, you can get your head pressure on the liquid line, but some systems may require you to connect to the discharge line to check the head pressure. A common rule of thumb is the 100-degrees over ambient rule; the temperature of the discharge line on a running system should be 100-110 degrees above the outdoor air temperature.What is the working pressure of R407C compared to R22? ... For R22, the discharge side is 240psi and suction side is 70 psi. Is it similar for R407C? ... 01-11-2010, 07:56 PM #2. ... ive found the running pressures different. suction pressure 50 psi and discharge 220 psi. but from what ive been told its quite an unstable refrigerant.

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.

I am an HVAC contractor and am noticing a pattern with several R-410A compressors in (less than one year old) heat pump systems we've installed. After a cold night, I'll get a call from someone saying their outside unit is noisey and system is not heating. What I see when I arrive is the compressor is running, but not pumping as pressures are equalized.The discharge pressure is the pressure on the high side of the system, where the refrigerant is condensing. For a standard heat pump using the popular refrigerant R-410a, the suction pressure should be between 35 and 45 PSI (pounds per square inch) when running in heating mode. The discharge pressure should be between 300 and 450 PSI.Find out about high-blood pressure during pregnancy. Some women with high-blood pressure develop preeclampsia.
