Mar 13, 2018 · For the normal running pressure in an R134A system, the coil should run at 22 pounds per square inch at the lowest temperature, 45−20 = 25 degrees Fahrenheit. Similarly, at the highest temperature, 60−20 = 40 degrees Fahrenheit, the coil should run at 57 psi. In other words, the normal running pressure of R134A is between 22 and 57 psi in ... We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG.

Low side: 30 to 36 psi. High side: 313 to 327 psi. Indications. Both pressures are TOO HIGH.A temperature-pressure chart can be used to compare the pressure of the refrigerant at a given temperature. Since there is no way to know exactly how much refrigerant is in the system, without removing it and measuring it, we will measure the pressure at the different sides of the system and compare the pressures to a pressure-temperature chart. Generally speaking, you want around 27-psi on the low side and 200 on the high side. Why 27-psi? Because, on an R-134a AC system, 27-psi. on your gauge means the refrigerant will produce about 32°F at the evaporator (as long as the orifice tube/expansion valve is operating properly and there’s no air in … See moreR134a Pressure Enthalpy Chart.
