Refrigerant R1234YF Critical Temperature/Pressure
WARNING: This page is about a different car, the 2024 Audi S6 and 2024 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
Up until a gas pressure of 32.82 bar (476.01 psi) pressure (equals a temperature of 94.7 °C (202.5 °F)), refrigerant will evaporate on the surface in the amount which then liquefies again when the vapor particles bond. Above this temperature / this pressure, there is no separating surface between liquid and gas anymore.
