عنوان انگلیسی Liquid Density Modeling of Pure Refrigerants Using Four Lattice-Hole Theory Based Equations of State
چکیده انگلیسی مقاله The present study investigates the performance and relative accuracy of four lattice-hole theory based equations of state in modeling and correlating the liquid density of pure refrigerants. Following the gathering of a database of 5740 experimental liquid density datapoints of 36 pure refrigerants belonging to five different categories including CFCs, HCFCs, PFCs, HFCs and HFEs, ranging from 6 × 10-5-500 MPa and 94-533 K, the pure component characteristic parameters of the EOSs were estimated and used in their comparative study. According to the results obtained, all the four EOSs can satisfactorily represent the liquid density of refrigerants with AARDs of only 0.654%, 0.684%, 0.798% and 0.859% for ε*-Modified Sanchez-Lacombe, Simha-Somcynsky, MSS-II and Park-Kim EOSs, respectively. Also, based on a comparison with the commonly used Peng-Robinson, as well as the linear isotherm regularity (LIR) EOSs, with AARDs of10.064% and 2.050%, respectively, in representing the liquid density data, it can be concluded that the large improvements obtained when using the lattice-hole theory based EOSs do justify the use of these more complex equations of state for modeling the volumetric properties of various pure refrigerants.
