Abstract

The use of refrigerant mixtures for R22 alternative has recently been attracted in refrigerating and air conditioning industry. However, there has not been enough information about thermodynamic properties required to analyse the properties of mixtures. In this paper, stressing the adaptability of the modified van der Waals equation of state for refrigerant mixtures, the prediction methods of thermodynamic properties for the a1ternative refrigerant and mixture are explained. Seven generalized equations of state are chosen for the subjects of discussion. Data on R32,R125,R134a and their mixtures are applied to discuss the adaptability of these equations. Resu1ts of calculation using these equations are compared with available experimental and reference data. The optimum binary interaction parameters for those equations of state are a1so presented.
