According to the result gives a new R407C refrigerant temperature and pressure enthalpy diagram and a entropy diagram. Correlations of high accuracy, thermodynamic parameter calculation error is less than 1%,[link widoczny dla zalogowanych], migration parameters error of less than 4%. The results of this paper is a new refrigerant R407C 56 analysis and computation system provides accurate and reliable physical properties of the thermodynamic properties and thermal analysis results.
