Quick Example: Let’s say that we have a 3-ton 16 SEER AC are using R-410A refrigerant and want to calculate R-410A superheat. With low side blue gauge on the suction line service port, we measured 130 psi pressure that correlates (according to R-410A PT chart) to about 45°F. The clamp-on thermometer shows that the saturated refrigerant ...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.R-410A is an HFC refrigerant that is a blend of the HFC R-32 and the HFC R-125. This refrigerant was designed to be a safe, non-toxic, non-flammable, and reliable alternative to the HCFC R-22. It was invented in 1991 but did not begin to see real popularity until the 2000’s. The normal pressure for a typical R-401A mini-split ranges from 110-140 psi. However, keep in mind that the working pressure depends on factors like cooling load and weather. According to experts, the working pressure should never be less than 100 psi or more than 160 psi. Jun 11, 2017 ...
