Calculation note: Values were generated with CoolProp 8.0.0 using the HEOS model for R134a. Pressure is absolute. Thermodynamic reference convention: CoolProp ASHRAE for R134a. Definition: Saturated liquid at −40 °C is assigned h = 0 kJ/kg and s = 0 kJ/(kg·K). Reference anchor for reproducibility: T = -103.3 °C, p = 0.38956379 kPa, Q = 0 (saturated liquid), u = -76.689297 kJ/kg, h = -76.689052 kJ/kg, and s = -0.38299348 kJ/(kg·K).
