REFRIGERANT COMPOSITIONS

摘要

A non-azeotropic (zeotropic) refrigerant composition is described. The refrigerant composition comprises (A) a first component comprising fluoromethane (R-41), (B) a second component comprising at least one hydrofluorocarbon selected from the group consisting of 1,1,1,2-tetrafluoroethane (R-134a) and 1,1,2,2-tetrafluoroethane (R-134), and optionally (C) a third component comprising at least one hydrofluorocarbon selected from the group consisting of difluoromethane (R-32), 1,1,1-trifluoroethane (R-143a) and pentafluoroethane (R-125).
