FIELD: refrigerating agents. ^ SUBSTANCE: invention relates to a refrigerant, used in particular, for air conditioning. The composition of refrigerant involves fluorohydrocarbon component comprising 1,1,1,2-tetrafluoroethane (R 134a) and pentafluoroethane (R 125). The composition involves additionally additive taken among the group involving saturated hydrocarbon or their mixture boiling in the range of temperatures from -5oC to +70oC. Invention involves a diluting agent for refrigerant and a method for modifying the refrigerating system or the air conditioning system comprising R 22 as a refrigerant. Proposed compositions don't comprise chlorine atoms and don't exert harmful effect on ozone layer. ^ EFFECT: improved and valuable properties of agent. ^ 18 cl, 8 tbl, 3 dwg, 7 ex |
