A normally operating R-410A system with the same condensation temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig. How to Use a Two-Column Pressure-Temperature Chart Properties of the new zeotropic refrigerant blends are different than traditional refrigerants, it is useful to know how to read a two-column PT chart. Traditional PT charts list the saturated refrigerant pressure, in psig, with a column for temperature down the left side. Single-component refrigerants and azeotropes […]

R-13B1 in the low stage. For these systems, Freon™ 95 (R-508B) is a better replacement than Freon™ 410A. Properties Freon™ 410A is safe to use when proper storage and handling practices are followed. It is a nonflammable, low toxicity mixture of HFC-32 and HFC-125 (50/50 wt%). Freon™ 410A has been classified as A1 by ASHRAE andI am charging my heat pump it is an r410a and its about 90 degrees outside i have gotten the low side up from about 100psi to 130 and the high side from around 300psi to 340-50 is this about right what should my pressures be. The 410a part of the gauge is reading 44 low and 106 for high.All the low voltage wiring was a disaster. (Obviously done by someone who didnot know what they were doing). One system is R-22 and the other is R-410A. The 410 A system is not operating properly. I put guages on it (the new type for 410A) and the pressueres read 35psi on the low side and 100psi on the high side. Suction line is sweating.
