摘要：
The invention relates to a ternary composition comprising difluoromethane, 3,3,3-trifluoropropene and a hydrocarbon-derived compound containing at least two fluorine atoms and having a boiling point of between −30 and −18° C., which is selected from 1,1-difluoroethane, 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene. This composition is particularly suitable for use as a heat-transfer fluid in the presence of countercurrent heat exchangers.
