| 内容記述 | The vapor-liquid equilibrium (VLE) of alternative refrigerants was computed using the Patel-Teja (PT) equation of state, and its validity was examined. The equation of state has three parameters, and the third parameter is introduced to lessen a failure of two-parameter equations of state in a prediction of liquid density. Expressions of fugacity, residual enthalpy, and residual entropy were derived first. It was confirmed that the PT equation of state yielded reasonably accurate predictions of saturation properties for the pure substance of alternative refrigerants. Relative errors of the predictions from the formula or the correlation developed exclusivelry for the pure substances were less than 4 percent. In a prediction of the VLE for the mixtures, values obtained from the PT equation of state showed a good agreement with actual measurements. The maximum relative error of equilibrium composition or bubble-point pressure was about 2 percent. It was concluded that the PT equation of state can represent the VLE of alternative refrigerants and their mixtures with sufficient accuracy. | |||||||
