FIELD: special-destination fluids.
SUBSTANCE: agent intended for use in cooling systems, in particular in air-conditioning systems, contains 83-99% 1,1,1,2-tetrafluoroethane, 1-17% pentafluoroethane, and an additive selected from saturated hydrocarbons and their mixtures boiling within a temperature range from -5 to +70оС, preferably from pentane, isopentane, cyclopentane, and their mixtures. Advantageously, percentage of additives ranges from trace to 10% and more preferably from 1 to 8%.
EFFECT: reduced inflammability and increased miscibility resulting in better return of lubricant into system allowing replacement of environmental dangerous constituents.
