FIELD: machine building.
SUBSTANCE: heat accumulators are used for pre-starting heating power systems of building machine at period of inter-shift down-time in winter. Heat accumulating material contains 2-3 g of edible gelatine, 2-3 g of sodium chloride and 1-2 g of sodium hydroxide per 100 g of over saturated solution of three-water sodium acetate.
EFFECT: improved operational characteristics of heat accumulating material such as temperature of reaction, temperature of self-crystallisation and temperature of phase transition.
