Abstract
(EN)
A refrigerant composition is described which comprises (A) at least one hydrofluorocarbon selected from the group consisting of difluoromethane (R-32) and 1,1,1-trifluoroethane (R-143a), (B) pentafluoroethane (R-125), (C) perfluoropropane (R-218), and optionally (D) 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).
