If the system's pressure is 250 PSI, using the Superheat Calculator 410A, we can calculate the superheat as follows: See also Gutter and Downspout Calculator Online. Superheat = 45°F - 65°F = -20°F.I am wondering what the high and low pressures should be in a 3-ton 410a refrigerant AC system. The installer seemed very unsure of himself. It was 88 or 90 degrees F (and humid outside) and he ended up setting (leaving?) the pressures at 142 psi on the low side and 350 on the high side. He said something about a 200 psi difference being normal.R-22 system would have a compression ratio of 3.02:1, while the R-410A system would have a compression ratio of 2.98:1. The actual efficiency gains from R-410A are due to its superior thermodynamic values over R-22.
