R-407A was developed as a close match to R-22's capacities and flow rates, making it well suited as an energy efficient retrofit for R-22 in medium and low temperature refrigeration systems for supermarket and food storage applications, but not for air conditioning systems or those with flooded evaporators. [2] It must be used with synthetic ...

The zeotropic mix of difluoromethane with pentafluoroethane and tetrafluoroethane is known as R-407A through R-407F depending on the composition. Likewise, R-504 is the azeotropic (48.2/51.8 mass%) mixture of difluoromethane and chlorotrifluoromethane (R13). In 2011 17,949,893 metric tons of difluoromethane were emitted into the atmosphere in ...
