Résumé

In this study, we have developed Polyol Ester (POE) oils with excellent electrical performance suitable for electric compressors. The chemical structure of the POE is designed appropriately to show good miscibility with R134a and R1234yf, the refrigerants generally used in car air conditioners. Additionally, it is also achieved to improve the refrigeration oils viscosity at low temperature. For new energy vehicles (NEVs), it is expected to use heat pump heating in cold environment to prevent power consumption. Our newly developed POE oil is flowable at low temperature under 0 °C, it therefore should be applied for the heat pump heating system. The POE refrigeration oils presented are expected to be used in car air conditioners of NEVs.
