R-134a saturation table by pressure

Name: R-134a saturation table by pressure
Creator: Simuveliq

This table gives saturation temperature and properties of saturated liquid and vapor for each pressure. Above you can use it interactively (switch units with SI/US, pick the pressure or go to the calculator for any point with step-by-step interpolation). Reference state: ASHRAE: h = 0 and s = 0 for saturated liquid at −40 °C (−40 °F).
