Khimenko O. Enhancement the efficiency of solid electric thermal storages by improving their dynamic performance

Object of research - solid state electric thermal storage. Objective is to study heat transfer processes in a solid heat storage elements of electric thermal storage (ETS) to improve its dynamic performance in the charge mode and the heat output mode. Research methods - methods of mathematical simulation of heat transfer processes in the charge mode and the heat output mode and calculation-experimental methods of study. Theoretical and practical effects - proposed in the thesis, the methodology of thermal calculation of ETS, which takes into account the thermal characteristics of the charge mode and the heat output mode, resulting from the processing of experimental data, can be used in engineering calculations and construction of ETS. Novelty is based on the complex calculation and experimental study, quantitative and qualitative estimate of the effectiveness of storage and heat output of ETS and the determined thermal characteristics in the modes of charge and the heat output. Degree of implementation - results of the work are to be implemented by the Institute of renewable energy of NAS of Ukraine for the fulfilment of the system of electric heating using solid-state electric thermal storage. Area of application - electric thermal storage heating.
