(WO9903947-A1)      A refrigerant composition comprises (A) 5-60 wt.% of pentafluoroethane, octafluoropropane, trifluoromethoxydifluoromethane, hexafluorocyclopropane or their mixture, (B) 30-94 wt.% of 1,1,1,2- or 1,1,2,2-tetrafluoroethane, 1,1-difluoroethane, trifluoromethoxypentafluoroethane, 1,1,1,2,3,3,3- or 1,1,1,2,2,3,3-heptafluoropropane or their mixture and (C) 1-10 wt.% of an unsubstituted hydrocarbon of formula CnHm (where n 4 and m 2n-2) other than methyl propane.    Also claimed are a refrigerating apparatus and process using this refrigerant.    USE -   The refrigerant is used as a replacement for chlorofluorocarbons R12 and R22 in domestic refrigerators and air conditioning systems etc.    ADVANTAGE -   The flammability of the fractionated composition is greatly reduced.
