REFRIGERATING MEDIUM COMPOSITION Russian patent published in 2006 - IPC C09K5/04

Abstract RU 2280667 C1

FIELD: special-destination fluids.

SUBSTANCE: invention provides refrigerating medium designed for use in household and industrial refrigerating equipment, in particular composition including no chlorine-containing compounds, which composition contains 20-85% difluoromethane, 8-78% difluoroethane, and one of unsaturated C₃-C₄-hydrocarbons, which serve to further reduce global warming potential owing to their being substances with zero GWP factor. Composition is characterized by vapor close to that of chlorodifluoromethane with phase equilibrium at temperatures between -50°C to +50°C and is ozone safe so that can substitute Chladone 22 in refrigerating equipment and in conditioners.

EFFECT: enlarged choice of chlorine-free refrigerating media.
