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. Heat capacity ratio at 86°F: 1.178253.At atmospheric pressure, the R134a has a boiling point of -26.8 o C and at 10psi pressure, its boiling point rises to -10.6 o C. If R134a is released into a room at atmospheric pressure and room temperature, it would instantly turn into gas. The temperature and pressure of the refrigerant have a direct relationship.What should my gauge readings be on 410a on 95 degrees at condenser. looking at pt chart at 95 ...
