Thermodynamic Properties of HFC-134a Refrigerant(1,1,1,2-tetrafluoroethane)

Engineering (I/P) Units

New tables of the thermodynamic properties of HFC-134a have been developed and are presented here. These tables are based on experimental data from the database at the National Institute of Standards and Technology (NIST). Equations have been developed, based on the Modified Benedict-Webb-Rubin (MBWR) equation of state, which represent the data with accuracy and consistency through- out the entire range of temperature, pressure, and density.

Physical PropertiesChemical Formula CH2FCF3

Molecular Weight 102.03

Boiling Point atOne Atmosphere –14.9°F (–26.06°C)

Critical Temperature 213.9°F (101.08°C)673.6°R (374.23 K)

Critical Pressure 588.9 psia (4060.3 kPa [abs])

EquationsThe Modified Benedict-Webb-Rubin (MBWR) equation of state was used to calculate the tables of thermodynamic properties. It was chosen as the preferred equation of state because it provided the most accurate fit of the thermo- dynamic data over the entire range of temperatures and pressures presented in these tables. The data fit and calculation of constants for HFC-134a were performed for Du Pont at the National Institute of Standards and Tech- nology (NIST) under the supervision of Dr. Mark O. McLinden.

The constants were calculated in SI units. For conversion of thermodynamic properties to Engineering (I/P) units, properties must be calculated in SI units and converted to I/P units. Conversion factors are provided for each prop- erty derived from the MBWR equation of state.

Properties calculated in SI units from the equation and constants listed above can be converted to I/P units using the conversion factors shown below. Please note that in converting enthalpy and entropy from SI to I/P units, a change in reference states must be included (from H = 200 and S = 1 at 0°C for SI units to H = 0 and S = 0 at –40°C for I/P units). In the conversion equation below, H (ref) and S (ref) are the saturated liquid enthalpy and entropy at –40°C. For HFC-134a, H (ref) = 148.4 kJ/kg and S (ref) = 0.7967 kJ/kg • K.

2. Martin-Hou Equation of State (fit from MBWR data)

As previously stated, the thermodynamic propertiespresented in these tables are based on the MBWR equation of state. Coefficients for the Martin-Hou equation of state are presented below for the conve- nience of those who may have existing computer programs based on this equation of state. While not as accurate as the data from the MBWR equation of state, particularly in the superheated region, data calculated using these Martin-Hou coefficients should be suffi- cient for most engineering calculations.
