Working models of energy accumulator the newest design and a new type of organic accumulating material with improved thermal conductive structure have been created, an autonomous system of energy supply for consumers with a heat accumulator has been developed, the dependence of the operating parameters of such system on the thermophysical processes of converting and accumulating energy in the phase transition phase has been investigated.

A new, comprehensive approach in the study of the processes of heat and mass transfer during the phase transformations of the accumulating material, which was first used in the world and national science for the study of melting/crystallization processes around several cylindrical heat sources, which are placed in an array of pure and reinforced by heat-conducting inclusions (micro- and nanoparticles of metals) of the accumulating material is formed and tested.

The obtained new scientific results have allowed: to create a new method of calculation of high-efficiency designs of accumulators of heat of phase transition of shell-tube type; to develop the newest design of the combined energy accumulator and the new type of organic storage material with the improved (strengthened) thermal conductive structure; to solve the problem of optimization of the choice of component composition of systems of integrated energy supply depending on the climatic conditions of accommodation and power of the consumer, which made it possible to carry out the processes of energy storage/use in the most optimal mode.

Several active samples of energy accumulator the newest design have been implemented.

In comparison with the world's analogues, the development of the mass-grossing parameters is less by 15 % and 86 % better than the duration of the operation in the «discharge» mode at the same thermal power with the sample-analogue.

It was introduced: LLC «Reduce Energy», OJSC «Joint-stock company «Pivdentransenergo», NULES of Ukraine.

The economic effect of introducing development – by 40…45 %, the cost of 1 Gcal of thermal energy decreases, the reliability of energy supply increases by 15 %.
