Abstract
The use of a ternary composition of 2,3,3,3-tetrafluoropropene, 1,1,1,2-tetrafluoroethane and difluoromethane, as a heat-transfer fluid, in compression refrigeration systems with exchangers operating in counterflow mode or in cross-flow mode with counterflow tendency. A heat-transfer process in which a ternary composition of 2,3,3,3-tetrafluoropropene, 1,1,1,2-tetrafluoroethane and difluoromethane is used as a refrigerant in compression systems with exchangers operating in counterflow mode or in cross-flow mode with counterflow tendency.
