Thermodynamic Properties of R134a TetraFlouroEthane - CF3CH2F. With the discovery of the damaging effect of CFCs and HCFCs refrigerants to the ozone layer, the HFC family of refrigerant has been widely used as their replacement.

R134a is also known as Tetrafluoroethane (CF3CH2F) from the family of HFC refrigerant. However, the liquid–vapor boundary terminates in an endpoint at some critical temperature T c and critical pressure p c. This is the critical point.
