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.
The refrigerant R134a remains chemically stable up to a gas pressure of 39.5 bar (572.9 psi) (absolute pressure of 40.56 bar (588.27 psi), which corresponds to a temperature of 101 °C (213.8 °F)). Above this temperature, the refrigerant breaks down (refer to "Combustibility").
