FIELD: chemistry.
SUBSTANCE: invention relates to heat carrier compositions. The heat carrier composition contains: about 5 to 40 wt % trans-1,3,3,3-tetrafluoropropylene (R-1234ze(E)), about 20 to 35 wt % fifluoromethane (R-32), about 15 to 30 wt % pentafluoroethane (R-125), and about 12 to 50 wt % 1,1,1,2-tetrafluoroethane (R-134a).
EFFECT: invention enables to obtain a heat carrier composition with low global-warming potential (GWP) and toxicity.
