Refrigeration system using mixed refrigerant and mixed refrigerant

摘要

The present invention provides 40% or less of 1,1-difluoroethane, 40% or less of difluoromethane (CH ₂ F ₂ ), and 20 to 80% of 1, 1, 1, 2-tetrafluoroethane or difluoromethane. (CH ₂ F ₂ ) 5-40%, pentafluoroethane (C ₂ HF ₅ ) 5-40%, 1, 1, 1, 2-tetrafluoroethane 20-90% azeotropic mixed refrigerant (Non -Azeotropic Refrigerant Mixtures and refrigeration systems using this azeotropic mixture as a refrigerant and using a Suction Line Heat Exchanger.;There is no possibility of ozone depletion of the mixed refrigerant of the present invention and shows a similar or superior effect in terms of the freezing capacity of the refrigeration performance coefficient compressor as an alternative refrigerant of the existing R-22 in a refrigerator using a suction tube heat exchanger.
