Nakashidze L. Energy effective systems for providing indoor climatic conditions on the basis of energy of the sun and environment

The object of the research is the creation of scientific and technological principles for the construction of energy-efficient systems for providing climatic conditions in premises on the basis of the use of solar radiation and the environment. The purpose of the dissertation work is to scientifically substantiate the construction of systems for providing climatic conditions in premises on the basis of the use of various types of renewable sources energy, creation of new technical means of converting energy from renewable sources. Methods of research. -methods of numerical simulation, statistical methods for analyzing the results of numerical experiment, methods of mathematical modeling and structural analysis. As a result of the research, the following scientific and practical results were obtained. For the first time: energy-active means of transformation of solar radiation energy are provided, which provide controlled acquisition, redistribution, accumulation of energy; A new approach to experimental modeling of heat engineering characteristics of such converters has been developed, for the possibility of unification of research results for different designs and modes of energy exchange. Developed: scientific and methodological bases for the construction of low-temperature power supply systems, which allows the introduction of thermal protection regulation with the possibility of combining thermal accumulation. Improved: scientific principles of calculation and development of circuit solutions of power supply systems that take into account the interaction of structural elements during operation, which makes it possible to determine the optimal correlation between components of the system depending on the operating conditions; methodological principles of calculation of technical and economic efficiency of systems .. The practical value of the results obtained. The received scientific and practical results can be used by participants of investment programs and projects of energy saving. The results of the dissertation work have been implemented at such enterprises as the State Enterprise "Investment-Innovation Center" of Dnipropetrovsk Regional State Administration; Municipal Enterprise "Agency for the Development of the Dnipro River" of the Dnipro City Council; LLC "NOVOTEKH LTD" (Dnipro, Ukraine), in cooperation with the NGO "Black Sea cluster" (Varna, Bulgaria), which is confirmed by the relevant implementation acts. The obtained results are used in the educational process of Dnipropetrovsk National University of Railway Transport named after V. Lazaryan and Dnipro National University named after Oles Honchar.
