The new method use EOS of pure substitutes to calculate thermal properties of mixed working substitutes. It has a higher degree of accuracy than Peng-Robinson EOS with reckoned interactive coefficient Kij given only critical thermodynamic properties of the working substances.展开更多

The equation presented here has a simple and generalform, and has a comparable accuracy for prediction of the vapor pressure of fluids. Only thecritical temperature, critical pressure, acentric factor w and polar factor x are required forprediction. Satisfactory results are available for various kinds of substances such as simplefluids, quantum fluids, hydrogen-bond fluids, non- polar fluids, polar fluids, refrigerents andassociated fluids etc..展开更多
