Refrigerant R1234YF Critical Temperature/Pressure — 2015 Audi A3 Premium, 4D Sedan Service Manual

Refrigerant R1234YF Critical Temperature/Pressure

Up to a gas pressure of 32.82 bar (476 psi) (this corresponds to a temperature of 94.7 °C (202.46 °F)) the quantity of refrigerant evaporating from the surface equals the quantity returning to the liquid state as vapor particles condense. Above this temperature/this pressure there is no longer a boundary between liquid and gas.
