Similarly, we can see that the vapor pressure of R422D on a 90-degree is 184.2 psig. Example 7: What Are R422D Pressures On A 95-Degree Day? From the PT chart, we can read that the pressure of liquid R422D on a 95-degree day is 211.8 psig.From Fig. 1 it results that expected two-phase pressure drops of R422D should be lower than those corresponding to R22 and R407C for all values of vapor quality. The differences become more evident using Eq. (2).The results showed in Fig. 1 are due to the fact that, for all values of vapor quality, ϕ 1,R 422 D is lower than ϕ 1,R 22 and ϕ 1,R 407 C, while R22 and R407C show a ϕ v larger ...
