FIELD: chemistry.
SUBSTANCE: invention relates to heat-transfer compositions, applied in cooling systems and heat-transfer devices. Heat-transfer composition contains trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)), difluoromethane (R-32) and 1,1-difluoroethane (R-152a) as coolants.
EFFECT: claimed heat-transfer composition possesses combination of improved properties of productivity of cooling and mixability with lubricating materials with low inflammability and low global warming potential (GWP) in comparison with separate coolant and known heat-transfer compositions and makes it possible to replace existing coolants, possessing considerable GWP.
