Résumé

A better knowledge of the transport and thermodynamic properties for the refrigerant-lubricant system is required to properly design the refrigeration circuit. This is essential also to develop proper models able to predict the behaviour of the mixture refrigerant-lubricant depending on the working conditions. However, the experimental data available in literature are insufficient to build dedicated models, being frequently related to commercial lubricants with undefined structure. Recently, a series of measurements have been performed at isothermal conditions with a static method to evaluate the solubility of carbon dioxide in commercial POE lubricants and pure pentaerythritol tetraalkyl esters (both linear and branched) as POE precursors. In parallel, the Peng-Robinson-Stryjek-Vera equation of state, with the Huron-Vidal mixing rules was selected for the correlation of the solubility data. The paper presents a discussion on the solubility data obtained and their correlation with the selected model, with particular reference to the influence of the lubricant structure.
