More Information
Summary:The invention pertains to heat transfer compositions, particularly to automobile refrigerants comprising a hydrofluoroalkene, an iodocarbon, and at least one lubricant having hydrogen atoms and carbon atoms, wherein no more than 17% of the total number of hydrogen atoms which are attached to a carbon atom are tertiary hydrogen atoms. L'invention concerne des compositions de transfert thermique, en particulier des réfrigérants automobiles comprenant un hydrofluoroalcène, un iodocarbone et au moins un lubrifiant ayant des atomes d'hydrogène et des atomes de carbone, moins de 17 % du nombre total d'atomes d'hydrogène qui sont liés à un atome de carbone étant des atomes d'hydrogène tertiaires.
