About R134aTablesPPC
HFC-134a (1,1,1,2-tetrafluorethane) is an environmentally acceptable refrigerant
which has replaced the ozone depleting CFC-12 (dichloro-difluoro-methane) in a
wide range of applications.
The R134aTablesPPC application calculates 12
thermodynamic properties of (1,1,1,2-tetrafluorethane). It allows 3 different
combinations of input variables to be used in calculations.
Input variables that can be used are:
- pressure,
- temperature,
- and quality (vapor mass fraction).
Used Formulation
For thermodynamic properties the library uses new industrial
formulation for R134a (1,1,1,2-tetrafluorethane), formulated in Helmholtz
energy. It is intended to be used for advanced technical applications. Equation
of state was presented in "Equations of State for Technical Applications" by R.
