摘要：This paper contains an experimental analysis of a heat storage tank's heat loss and exergy efficiency using a basalt porous bed as a storage material. The basic parameters of the laboratory bench with measuring equipment are presented and the experimental procedure is discussed. The methodology for evaluating the energy potential of the heat storage process for large-scale energy storage systems is described. The main novelty of the presented system is the application of the slenderness of the heat accumulator, which corresponds to the development of the system in a post-mining shaft. Based on the analysis of the experiment, the exergy cycle efficiency of the heat storage unit was determined to equal 52.3%, and the energy efficiency equal to 96.6%.
