Abstract:

A refrigeration system including a flooded evaporator. The flooded evaporator additionally includes a liquid evaporator refrigerant composition and a vapor evaporator refrigerant composition. The liquid refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf) and the vapor refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf). The mass fraction of difluoromethane in the liquid evaporator refrigerant composition is lower than the mass fraction of difluoromethane in the vapor evaporator refrigerant composition and the mass fraction of 2,3,3,3-tetrafluoropropene in the liquid evaporator refrigerant composition is greater than the mass fraction of 2,3,3,3-tetrafluoropropene in the vapor evaporator refrigerant composition.
