R-513A saturation table

Name: R-513A saturation table
Creator: Systcold JDC

A1 · GWP 631

Zeotropic blend with glide: liquid (bubble point) and vapour (dew point) pressures differ at the same temperature. Use dew for superheat and bubble for subcooling.

Systcold calculation with CoolProp (R513A.mix). Gauge pressure relative to standard atmosphere (1.013 bar); at other altitudes gauge pressure changes. Enthalpy and entropy use the CoolProp reference state (IIR for pure fluids: h = 200 kJ/kg and s = 1 kJ/kg·K for saturated liquid at 0 °C): compare with tables using the same reference or use differences.
