Zusammenfassung:	FIELD: chemistry.SUBSTANCE: invention relates to field of heat-transmitting compositions. Heat-transmitting composition contains in fact from approximately 60 to approximately 85 wt % of trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)) and from approximately 15 to approximately 40 wt % of fluoroethane (R-161). Invention also deals with heat-transmitting composition, which includes R-1234ze(E), R-161 and 1,1,1,2-tetrafluoroethane (R-134a).EFFECT: invention provides reduction of toxicity, combustibility and GWP of heat-transmitting composition with productivity factor within 10% of values achieved with application of existing refrigerants.53 cl, 11 tbl, 1 dwg Изобретение относится к области теплопередающих композиций. Теплопередающая композиция содержит по существу из от около 60 до около 85 мас.% транс-1,3,3,3-тетрафторпропена (R-1234ze(E)) и от около 15 до около 40 мас.% фторэтана (R-161). Также изобретение касается теплопередающей композиции, включающей R-1234ze(E), R-161 и 1,1,1,2-тетрафторэтан (R-134a). Изобретение обеспечивает понижение токсичности, горючести и GWP теплопередающей композиции при КПД в пределах 10% от величин, достигаемых при использовании существующих холодильных агентов. 21 н. и 32 з.п. ф-лы, 11 табл., 1 ил.
