Abstract
A heat transfer method using ternary compositions containing 2,3,3,3-tetrafluoropropene, 1,1-difluoroethane and difluoromethane, said compositions being especially interesting as a heat transfer fluid in compression refrigeration systems comprising exchangers operation in counterflow mode or in split flow mode with counterflow tendency. The use of a ternary composition of 2,3,3,3-tetrafluoropropene, 1,1-difluoroethane and difluoromethane as heat transfer fluid in compression-type refrigeration systems with exchangers operating in countercurrent mode or in crossed-current mode with countercurrent tendency.
