Critical Pressure (psia) 723.7 Critical Temperature (°F) 205.1 C 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 ...
