The purpose of research - development of scientific and technological bases of creation of highly efficient cogeneration plants based hydrogen thermochemical cycles using intermetallic compounds as energy converters and hydrogen as an energy carrier. Research methods: System Analysis and synthesis using mathematical modeling and experimental study of fundamental processes taking place in the power equipment of the cogeneration unit. It uses an integrated approach to solving the main objectives of the project, which consists in taking into account the interaction and mutual influence processes that occur in heat engines and cogeneration equipment using thermochemical cycles. Results of the research: 1. At ffirst identified conjugate fundamental thermodynamic and thermochemical processes that occur in the metal hydride hydrogen duty cycles cogeneration and tri-generation systems, rational agreement which allows the conversion of low potential heat (350...500 K) with high efficiency (20...22%) in mechanical/electrical energy and cold energy. 2. Determined the fundamental properties of reversible hydride-forming materials that allow effective im-plicitly convert low-potential energy into other forms of useful energy in continuous thermochemical hy-drogen cycles at an acceptable weight and dimensions of power equipment (mass indexes - 28...30 kg/kW, overall - 15...18 m3/1000 kW). 3. Determined the fundamental relationships that form the basis of a mathematical description of the thermochemical energy conversion using intermetallic compounds and hydride-forming adequately describe these processes. 4. At first developed a mathematical model of differential cogeneration and trigeneration power facilities, taking into account the complex thermodynamic and thermochemical energy conversion processes; exper-imentally proved its adequacy and accuracy defined simulation that does not exceed 15 %. 5. At first investigated conjugate fundamental processes that occur in systems thermochemical utilization of low-grade heat in cogeneration and tri-generation. Scientific novelty: 1.
