Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30.Physical Properties Of R22. In parallel to using the R22 PT chart, professionals will usually need to know some of the following R22 physical properties: R22 liquid density at -69°C: 1.49 g/cm 3. R22 gas density at 15°C: 3.66 kg/m 3. Triple point temperature: -115.76K. Critical pressure: 49.36 bar.
