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 |
