FIELD: refrigerating equipment. SUBSTANCE: the proposed mixture can be used as working body for refrigerated systems and heating pumps. Mixtures has: tetrafluoroethane, hydrocarbon and unsaturated fluorinated hydrocarbon of propylene order of the formula CFHwhere n = 1-6 at the following component ratio in mixture, mole %: tetrafluoroethane 1-94; unsaturated fluorinated hydrocarbon 1-94, and hydrocarbon 5-80. Use of this mixture ensures to increase the specific volume output, decrease boiling point under excessive pressure, for example, in refrigerated systems below 250 K. EFFECT: enhanced effectiveness of mixture. |
