R-134a saturation table by temperature

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

This table gives saturation pressure, specific volume, internal energy, enthalpy and entropy of saturated liquid and vapor for each temperature. 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).
