Dynamic models of energy flows of buildings are in the context of functioning of the engineering’s systems and business activity of users

Functionality of Smart Houme has certain limitations, among which is the inability to analyze the activity of the residents, determine its impact on energy consumption, identify the physical state of the user by his activities. There are no solutions that would be able to solve this
problem today. One approach is to use the activity analysis of binary motion sensors. The advantage of this approach is the low cost of implementation and privacy of the residents. The system functions in real time.

Development and research of superheated liquefied gas feeding system for internal combustion engines

A new technical solution is proposed that improves and simplifies the mixture process using the flashboiling effect and superheating. An experimental model of the developed liquefied gas engine power system in the liquid state is designed, which allows to improve the energy and environmental performance of the engine, to reduce the consumption of expensive traditional fuel and to bring cheap environmentally friendly gas fuels to the engine.

Complex energy supply systems for the autonomous objects based on the renewable energy sources

The autonomous power supply system for local object based on the photovoltaic panels and a buffer battery has been developed. Such system allows to balance the generation and consumption of energy. A mathematical model of the functioning of a complex power supply unit based on renewable energy sources has been developed.

The development of the diagnosing toolkit for guaranteed operation of the complex technical systems in the conditions of the uncertainties and destabilizing risk factors

Algorithmic toolkit for system estimation and forecasting of the guaranteed CTS functioning are proposed, the basis of which is the information platform for technical diagnostics. Algorithmic toolkit for guaranteed CTS operating implements the proposed concept and strategy for solving the problem of guaranteed CTS operating under the influence of destabilizing risk factors and uncertainties of various nature using the principle of timely identification of causes and preventing the transition to an abnormal mode with the estimating the margins of permissible risk for CTS indications.

The development of energy-efficient process for the high-temperature processing of bulk carbon materials in electric furnaces

The physical and mathematical models of the dynamics of the dense motion of a granular medium and the thermoelectric state of a single-phase mine electric furnace during high-temperature heat treatment of carbon material are formulated, on the basis of which the corresponding discrete and continuum numerical models of the physical fields of the electric calciner are developed taking into account the dense motion of the granular medium and chemical interaction.

Development of on-line platform for analysis and scenario planning of sustainable development of Ukrainian regions in the context of quality and security of people's life

The purpose of the work is to increase the completeness and effectiveness of analytical and information support of the management decision-making process (in the form of mid-term and long-term strategies and sequences of government actions) aimed at ensuring the sustainable development of regions and Ukraine, as complex socio economic objects, expense of developing new and improving existing systems analysis, big data mining, foresight, scenario planning and management and online platform for their application in situation center mode.

Aluminum two-phase heat transfer systems with steam and liquid separation for energy efficient technologies

Comparison of designs of heat exchangers with smooth-walled aluminum grooved heat pipes (AGHP) with a diameter of 8 mm and finned AGHP with an outer diameter of 43 mm. The use of smooth-walled AGHPs, on the one hand, results in a larger number of them in the heat exchanger compared to the finned AGHPs, but, on the other hand, results in a smaller pressure drop in the channels. On the basis of the experimental data, dependences were obtained for the calculation of the coefficients of heat exchange and aerodynamic resistance for a heat exchanger with smooth-walled AGHPs.
