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:

1. pressure,
2. temperature,
3. and quality (vapor mass fraction).

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. Span and W. Wagner, International Journal of Thermophysics, Vol.24, No.1, January 2003.
