Superheated R-22 vapor table

Name: Superheated R-22 vapor table
Creator: Simuveliq

This table gives v, u, h and s of superheated vapor in pressure blocks. 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).
