FIELD: heating engineering.
SUBSTANCE: invention proposes employment of anhydrous C1-C18-carboxylic acid alkali or alkali-earth metal salt(s) as medium for accumulation of heat and using heat energy. Method of improving heat-exchange properties and heat capacity of liquid comprises dispersing above-indicated salts therein. Invention allows selection of combinations of heat-accumulating salts, which are less toxic, less environmentally harmful, and less corrosive for metals and materials used in heat-accumulation and heat-transmission equipment.
EFFECT: improved heat-exchange characteristics of heat-accumulation materials.
