摘要

The article considers the issues of thermodynamic processes occurring in heat accumulators (HA) based on phase transition. A mathematical model of a heat accumulator with a number of assumptions is presented. To verify the correctness of the mathematical model, a number of experiments were conducted on a heat-accumulating substance (HAS) with similar modeling conditions, initial data and assumptions. Comparison of the experimental and calculation results showed the correctness of the proposed scientific and methodological apparatus taking into account the assumptions put forward.
