FIELD: refrigerating equipment.
SUBSTANCE: invention can be used in the manufacture of refrigerating plants and in air conditioning systems. Multicomponent coolant contains compressor oil, nanoparticles of metal oxides, neonol and aerosil. Compressor oil used is synthetic or mineral oil, or mixtures thereof. Nanoparticles of metal oxides are nanoparticles of copper oxide CuO, titanium oxide TiO2, aluminum oxide Al2O3, iron oxide Fe2O3, iron oxide Fe3O4 or tungsten oxide WO3.
EFFECT: invention makes it possible to increase heat transfer in heat exchange and refrigerating systems, to expand range of working temperatures, to reduce amount of used heat carrier and to increase service life of cooling liquid.
