Résumé

Lubricant selection is based on several lubricant properties to satisfied compressor and system reliability, longevity and energy efficiency performances. The use of non-miscible or low soluble lubricant can bring some technical advantage for the compressor and the system. This paper presents investigations results on low GWP refrigerant alternatives for light commercial and commercial applications. This experimental data are compared to well non data for usual refrigerant HFC/oil pairs. The work also targets the reduction refrigerant charge associated with the compressor characteristics. Miscibility of propane in an AKB, POE and PAG oils has been measured as well as resulting viscosity for each pairs. With too low viscosity values, AKB oil is not suitable for the compressors. PAG oil exhibits a low solubility compared to POE oil, and a miscibility limit that can be used to reduce the refrigerant charge in circuits.
