| 제목 | Measurements and Correlation of High-Pressure VLE of Binary CO2+1,1,1,2-Tetrafluoroethane (HFC-134a) Systems |
| 초록 | Generally, vapor liquid equilibrium(VLE) data are required as one of the most important types of information in evaluating the performance of refrigeration cycles and determining their optimal compositions. A blend of Carbon dioxide and nonflammable HFC refrigerant may reduce both, global warming potential and flammability. In this work, the VLE data of binary mixture containing 1,1,1,2-Tetrafluoroethane and Carbone dioxide were measured at various isotherms (323.15 ~ 363.15 K). To facilitate easy equilibration, both the vapor and liquid phases were circulated separately in the experimental apparatus. The equilibrium composition for both vapor and liquid phases were analyzed by a gas chromatograph. The measure data were correlated with Wong-Sandler mixing rules and the Peng-Robinson equations of state[PR-EOS]. We compared the obtained data by using the PR-EOS with experimental data and reached a satisfactory consistency. |
