Abstract

Technology of conservation of thermal energy is perspective direction for the modern systems of thermal and cold supply. To hire the methods of calculation of transfer of warmth and mass, results of experimental researches, are driven and drawn conclusion about financial viability of application of different substances for creation of mobile thermal accumulators. 

A review of the research of heat accumulators for the system of heat and cold supply is presented. An analysis of theoretical and experimental data on determining the geometric characteristics of the battery for the required amount of heat and cold, depending on the area of premises. Depending on the thermophysical properties of the heataccumulating material, it is possible to significantly reduce the volume of the heat accumulator by using thermal accumulators with a phase transition. The TAM study showed that bischofite-based batteries require 29.7 m3 for the accumulation of 1,0 MWh of heat, while for trihydrate sodium acetate will be spent only 17.4 m3. Implementation of discrete systems of heat and cold supply will create a vertically integrated energy holding company based in each region to generate cheap heat energy and coolant.
