Refrigerant R1234YF Vapor Pressure
WARNING: This page is about a different car, the 2021 Audi S4 and 2021 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
In a partially filled, closed reservoir, the quantity of refrigerant evaporating from the surface equals the quantity returning to the liquid state as vapor particles condense. This state of equilibrium occurs under pressure and is often called vapor pressure. Vapor pressure is dependent on temperature. Refer to REFRIGERANT VAPOR PRESSURE TABLE .
