摘要: A method to estimate the performance of single-stage vapor compression refrigeration systems as a function oil circulation ratio is presented. The model based on Peng-Robinson equation state and theory departure functions mixture enthalpy, entropy specific volume pressure, temperature composition. applied isobutane (R-600a) alkyl benzene oil. Pressure-enthalpy diagrams are presented ratio. These used in conjunction with thermodynamic cycle analysis which behavior overall parameters such cooling capacity, compressor power coefficient compared those obtained for baseline (i.e., pure refrigerant) condition.
