Analysis of the use of a thermo-hydraulic distributor in district heating schemes showed insufficient study of the mutual influence of the connected circuits, on which the coefficient of hydraulic stability of the heating network depends, and the lack of a comparative analysis of the efficiency of heat supply when using a scheme with a thermo-hydraulic distributor compared to widely used subscriber connection schemes. The purpose of the study is to compare the economic and energy efficiency of the proposed and existing subscriber connection schemes, which is an important task. In laboratory conditions, a wide range of studies have been carried out to study the hydraulic dependence of the contours of the thermo-hydraulic distributor among themselves. Processing of the results was carried out by the method of correlation-regression analysis and mathematical statistics. In a comparative analysis of subscriber connection schemes, methods of physical modeling of thermo-hydraulic modes were used. A comparative analysis showed that the energy efficiency of the scheme with a thermo-hydraulic distributor is higher in heating systems with non-automated subscribers, regardless of the temperature graph of the heating network. When comparing schemes with parallel connection of a hot water heater, it was found that the totality of electricity consumption for coolant circulation and fuel costs for a circuit with a thermo-hydraulic distributor turned out to be less irrespective of the temperature schedule. Statistical research methods confirmed the independence of the circuits and the normal supply of heat to the heating. New solutions have been obtained to increase the hydraulic stability of the centralized heat supply system using a thermo-hydraulic distributor at a heating point – the hydraulic stability coefficient of the heat network during all subscriber operation modes is equal to one. The results of the study can be used in the design of thermal points: the proposed heating system, the consumers of which will provide a stable hydraulic mode; existing heat supply system, the consumers of which must ensure the hydro-stable control of heat.

AbstractOne of the most promising energy sources is solar energy, which is confirmed by the growth in the development of renewable energy for European countries. The main goal of research is to design and implement the latest energy systems for passive buildings using renewable energy. In this paper is documented the optimal operation stages of the solar heat supply system were investigated with recommendations for further development of the design and construction of passive buildings in Ukraine South.

Introduction. One of the main directions of ensuring the sustainable development of the national economy and its regions is the reform of the energy sector, which can take place through the modernization or innovation of its components. An important component of these reforms is to provide the population with the environmentally friendly and socially safe thermal energy. At the present stage of management, the heat supply is the most costly branch of public utilities, which is supplemented by the problems of the inefficient fuel balance structure; worn-out infrastructure and low energy efficiency. This highlights the need to study the management of modernization of the heat supply system in the region in view of the declared vectors of the long-term development. Object of research is the process of managing the modernization of the heat supply system in the region. Subject of the research is a set of scientific approaches and practical mechanisms of modernization of the heat supply system of the region in the context of ensuring its sustainable development. Objective. The conceptual foundations of modernization of the heat supply system of the region in the context of its sustainable development through the introduction of the innovative technologies both in the management process and in the energy sector itself is substantiated in the paper. Methods. The following general scientific methods were used during the research process: system, structural analysis, grouping, when studying the structural elements and isolation of problems of development of the heat supply system of the region; historical analysis, when considering the scientific principles and institutional mechanism of modernization of the region’s heat supply system; comparative analysis in assessing the possibilities of the green transition of the heat supply system of the region and also when considering the features of the use of grant resources in the modernization of the heat supply system of the region; economic analysis in assessing the current state of the district heating system, etc. results. The essential determinants of the heat supply system of the region are analyzed, the objective need, organizational and economic mechanisms for managing the modernization of the heat supply, taking into account the need for the balanced development of the energy sector of the region are verified. The scientific novelty of the obtained results lies in the substantiation of the conceptual approaches to the management of modernization of the heat supply system of the region by innovating the forms and methods of managerial influence on the heat supply system of the region. The conclusion is made about the following effective approaches in managing the modernization of the district heating system: planning of the sustainable development of the energy sector, development of programs for modernization of the district heating, implementation of the infrastructure and soft projects, implementation of the international projects, motivation of households and entrepreneurship in the heat sector, participation in the grant requests, in state crediting programs, realization of the business projects in the field of production of environmentally friendly fuel; conducting an information campaign among the population and other key market players to raise the awareness of the energy efficiency financing mechanisms. The practical significance of the obtained results is that the developed recommendations will be used to improve the organizational and economic mechanism of management of the district heating system modernization and ensure its sustainable development.

The article analyzes the current state of the Russian heat power engineering and identifies the main problems in its economic development. From the position of an integrated approach, the problems of the Russian heat supply system are divided into three categories: technological, economic and social. The using electricity for the needs of heat supply is determined as an effective way of solution these problems. In this context the electric heat supply is offered as an alternative to the modern heat supply system. The article identifies the main factors of electric heating, showing its economic advantages over other types of heat supply systems. On this basis the authors justify the prospects of electric heating system from the point of view of economic development of the Fuel Energy Complex and the national economy as a whole.
