Knowing the pressure and the temperatures associated to the machine you are working on is essential to being able to diagnose any possible issues. Ashrae standard 34 safety rating: During standstill, the ambient temperature can reach and exceed the critical temperature and the pressure can exceed the critical pressure.

Without Knowing The Temperatures You Are More Or Less Walking Blind.

The chart in figure 1 shows the triple point and the critical point on a phase diagram. Vapor density (bp,lb./ft^ 3) 0.294. Hfc systems always work subcritical because the condensing temperature never exceeds the critical temperature (e.g., 214 °f / 101 °c in the case of r134a).
