Vapor-liquid equilibria of HFC-161+HFC-32+DMF ternary mixture for low-grade heat driven absorption refrigeration system
Ternary mixture of fluoroethane (HFC-161) + difluoromethane (HFC-32) + N,N-dimethylformamide (DMF) is a promising working fluid for absorption refrigeration system which is an important energy saving technology receiving more and more attention. Investigation on vapor-liquid equilibrium (VLE) is necessary for further study and the application in absorption system of the ternary mixture. Therefore, an experimental system with continuous vapor-phase circulation is set up, measuring VLE data within temperature range of 283.15 to 323.15 K. The experimental data is correlated with Wilson and NRTL models, and BP-ANN method, respectively. The calculating data of Wilson model has the largest relative deviation of 5.14% and average relative deviation of 2.65% for vapor pressure, being the best one. The deviation of molar fraction data obtained with BP-ANN model has the best average relative deviation 3.07%. However, NRTL model provides a smooth predicted surface. The correlated parameters of the three models are given.
