Summary:

AbstractThe utilization of different types of energy in phase-transitional thermal accumulators and its further use for thermal development of different subsystems of hybrid vehicles enables to significantly increase their operational efficiency. The system of the combined utilization of thermal and electrical energy in phase-transitional thermal accumulators (TA) is offered. To charge TA, it uses thermal energy of exhaust gas, a coolant and motor oil of the internal combustion engine and electrical energy which is utilized by energy recovery system when braking the vehicle. It consists of consecutive stages of heat accumulation when charging TA from different energy sources of the hybrid vehicle, its storage and use for rapid heating of vehicle separate subsystems. The main heat and power characteristics of system components and heat accumulating materials used in phase-transitional TA have been justified. Schemes and designs of a physical model to utilize electrical energy using high-capacity condensers for charging phase-transitional TA have been offered. The results of experimental and computational studies show theoretical comparison of the main indicators of the developed system in charging phase transition TA using various types of heat-accumulating material from the thermal and electrical energy. The use of electric energy accumulated in capacitors of large capacity to charge TA allows diversifying energy flows and providing the working capacitance of the TA under varying operating conditions. The features of the equipment and the technology of using the system under investigation are selected depending on the operational requirements, climatic conditions and the purpose of the vehicle. Particularly useful the presented results of modeling thermal systems can be for the further use of hybrid technologies in transport
