FIELD: chemistry.

SUBSTANCE: invention relates to a coolant or heat carrier composition which contains an azeotropic or nearly azeotropic component, which contains 1-99 wt % HFC-1234yf and approximately 99-1 wt % HEC-134a and, optionally, at least one compound selected from a group consisting of propane, n-butane, isobutene and dimethyl ether. The coolant or heat carrier composition optionally contains at least one more component selected from lubricant substances, isotopic indicators, compatibility agents, dyes which are fluorescent in UV light, soluble agents, stabilisers, water absorbers and deodorant agents. The composition is used in refrigerator installations, air conditioners and heat pumps, for cooling or heating, as liquid heat carriers, foaming agents, aerosol propellants and agents for suppressing or extinguishing fire.

EFFECT: composition with low global warming potential and low ozone layer depletion potential.
