Normal 410a pressures.

What is the low side and high side pressure for R410A? A typical R-22 system operating normally with a head pressure of 260 psig at a 120-degree condensing temperature and a low side pressure of 76 psig at a 45-degree evaporator saturation temperature will find the equivalent pressures in a R-410A system to be much higher.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.Nov 2, 2003 · Using the previous examples comparing the operating pressures of an R-22 system to an R-410A system, the 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. barg.

High and low blood pressure problems affect both men and women.Jun 24, 2020 · During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on the wet bulb temperature inside the building and the ambient temperature outside the building.

OPERATING PRESSURE POINTS “Systems using R-410A operate at higher pressures [than R-22],” points out the Field Diagnostics team. “For example, to produce an evaporating temperature of 40 degrees F and a condensing temperature of 115 degrees, the suction and head pressures would be 83 psia and 257 psia in an R-22 system, while they would be 133 and 406 psia, respectively, in an R-410A ...

Suction Pressure / EVAP DTD Rule of Thumb Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient.
