| Abstract: | Fast calculation of the refrigerant thermodynamic properties is fundamental and important for engineering calculations, especially for the refrigeration system simulation. In this work, the implicit curve-fitting method combined with the Martin-Hou EOS is developed for the curve-fit of superheat properties of refrigerant gas. The continuity between superheat gas region and saturation vapor line is guaranteed in present method. Case studies using refrigerants R12, R22, R134a and R600a, in common encountered temperature range show high agreement to the reference data and good flexibility in the refrigeration system simulation. |
