2 Thermodynamic Properties of HFC-134a Refrigerant (1,1,1,2-tetrafluoroethane) S Units New tables of the thermodyoamic properties of HFC-134a have been developed and are presented here. These tables are based 00 experimental data from the databas e at the National nstitute of Standards and Technology (NST). Equations have been developed, based on the Moditied Benedict-Webb-Rubin (MBWR) equation of state, which represeot the data with accuracy and consistency throughout the entire range of temperature, pressure, and density.

R = J/(mole) (K) for HFC-134a. R = S k1/kg K One atmosphere = k.pa Reference point for emhalpy and entropy: hr = 200 k1/kg at O C sr = 1 k1/kg K at O C Equations The Modified Benedict-Webb-Rubin (MBWR) equation of state was used to calculate the tables of thermodynamic properties. t was chosen as the preferred equation of state because it provided the most accurate tit of the thermodynamic data over the en tire range of temperatures and pressures presented in these tables. The data tit and calculation of constants for HFC-134a were performed for Du Pont al the National nstitute of Standards and Technology (NST) under the supervision of Dr. Mark O. McLinden. The constants were calculated in S umts. For conversion of thermodyoamic properties to Eogioeering (P) units, properties must be calculated in S units and converted to P units. Conversion factors are provided for each property derived from the MBWR equation of state. 1.

Please note that in eonyerting enthapy and entropy from S to P units. a change in refereoee states must be iocluded (from H = 200 and S = 1 at O C for S units to H = O and S = O at -40 C for P units). lo the eonversion equation below, H (reí) and S (reí) are the saturated liquid enlhalpy and entropy at -40 c. For HFC-134a, H (ref) = kj/kg and S (ref) = kj/kg K.
