FIELD: heating.
SUBSTANCE: claimed invention relates to heat exchange composition to be used for replacement of existing coolants that must have the decreased potential of global rise in temperature. Said heat exchange composition consists of, in fact, approx. 82-88 wt % of trans-1,3,3,3-tetra fluoropropren (R-1234ze (E)) and 12-18 wt % of 1,1-difluoroethane (R-152a). This invention discloses also the heat exchange composition containing approx 5-85 wt % of R-1234ze (E), 2-20 wt % of R-152a and 5-60 wt % of 1,1,1,2-tetrafluoroethane (R-134a).
EFFECT: coolant with decreased potential of global rise in temperature, lower toxicity and inflammability.
