FIELD: chemistry.
SUBSTANCE: invention refers to compositions containing 2,3,3,3-tetrafluoropropene, and using them as a fluid heat medium. What is described is using a three-component composition of 2,3,3,3- tetrafluoropropene as a heat-transfer fluid in refrigeration systems to substitute the mixture R-410A. The above composition contains 40 to 58 wt % of 2,3,3,3- tetrafluoropropene, 2 to 10 wt % of 1,1-difluoroethane and 40 to 50 wt % of difluoromethane. What is also described is a method for heat transfer with using the above composition.
EFFECT: invention provides a zero value of the ozone layer depletion (ODP) and a warming potential (GWP) lower as compared to R-410A with an increased efficiency coefficient.
