FIELD: chemistry.
SUBSTANCE: claimed invention relates to the application of a three-component composition, containing 2,3,3,3-tetrafluoropropene, 1,1,12-tetrafluoroethane (GFU-134a) and difluoromethane (GFU-32), as a liquid heat carrier in compression refrigerating installations, containing heat exchangers, working in a counterflow mode or in a transverse mode with a bias for the counterflow mode. The invention also relates to a method of heat transmission, in which the said three-component composition is used as a coolant.
EFFECT: invention demonstrates unexpected advantages relative to the volume productivity (% CAP) and cooling coefficient (% COP), which makes it possible to exploit them in systems with a smaller pipe diameter, and therefore with the greater efficiency of equipment functioning.
