Critical Temperature/Pressure

WARNING: This page is about a different car, the 2023 Audi SQ8, 2023 Audi RS Q8, and 2023 Audi Q8. 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").
