| 摘要 |
The present invention relates to heat transfer compositions comprising 2,3,3,3-tetrafluoropropene, difluoromethane, pentafluoroethane, and 1,1,1,2-tetrafluoroethane for use in refrigeration, air-conditioning, heat pump systems, and other heat transfer applications. The inventive heat transfer compositions can possess reduced global warming potential while providing good capacity and performance. |
