This paper presents a theoretical evaluation of the influence of compressor oil admixtures on the thermodynamic performance of a vapor compression system using natural refrigerant R600a. The performance determination is based on the developed pressure-enthalpy diagrams (P-h) for the refrigerant oil solution (isobutane-mineral compressor oil Azmol). A method for calculating the enthalpy of refrigerant-oil solutions has been proposed and the influence of the compressor oil admixtures to isotherms the pressure-enthalpy diagrams has been analyzed. The change of enthalpy at the different oil concentrations in the working fluid in an evaporator has been investigated. An application of the developed refrigerant-oil P-h diagrams for the theoretical evaluation of the efficiency of the vapor compression systems is also demonstrated. © 2009 Elsevier Ltd and IIR.
