The results of an analytical review of a large number of publications on the problem of improving the efficiency of thermoelectric generators (TEG) over the past decade are presented. An analysis of historical data on the thermodynamic justification of the efficiency of thermoelectric generators is presented.
In today’s environment, domestic enterprises are increasingly aware of the importance of transitioning to green energy. In this direction, organisations are considering emission standards, using energy-efficient technologies, considering environmental aspects of production, etc. Businesses that reduce their carbon footprint are generally more likely to attract investment. They are also more socially oriented and balanced in terms of sustainable development.
Сформульовано вимоги, обґрунтовано принципи побудови, розроблено узагальнену архітектуру інформаційно-аналітичної системи для оцінювання, прогнозування та управ- ління енергоефективністю економіки регіону, визначено основні функції компонентів.
The requirements have been formulated, principles of construction have been grounded, thegeneralized information-analytical system architecture for evaluation, forecasting and energy efficiency management of regional economy has been developed, the main functions of components have been defined.
Predicting a building’s energy consumption plays an important role as it can help assess its energy efficiency, identify and diagnose energy system faults, and reduce costs and improve climate impact. An analysis of current research in the field of ensuring the energy efficiency of buildings, in particular, their energy assessment, considering the types of models under consideration, was carried out.
The paper presents the results of a study aimed at increasing energy efficiency in residential buildings, as well as an analysis of the humidity state and the possibility of condensation when using internal insulation. Numerical simulations were performed to confirm the results. The obtained results indicate that the use of mineral insulation "BETOL®" and aluminum foil used as a vapor barrier, applied from the inside, contributes to the improvement of thermal insulation of the walls and reduces the risks of condensation.
Innovative pricing mechanisms should motivate heat suppliers and consumers to move toward more sustainable energy systems and introduce low-temperature district heating systems and sector coupling in smart energy systems. Therefore, district heating regulation regimes should also be changed to stimulate transformations in the energy sector.
Considering general trend of energy consumption, according to which the amount of consumed energy increases, its cost and scarcity continuously increase. The 10–12 % of all energy is spent on drying processes in the world. At the current stage of the development of dehydration processes in Ukraine and the world, an urgent problem has arisen in the creation and development of highly efficient thermal technologies that would ensure minimal energy consumption for the process and high quality of the material.
The article is devoted to increasing the efficiency of the air conditioning systems of clean rooms, which maintain the microclimate parameters in a given range according to several indicators - the number and size per 1 m³ of dust particles, aerosols, microorganisms and pressure, humidity, and temperature.
Clean rooms are used in microelectronics, instrumentation, medicine and medical industry, pharmacology, laboratories, optics production, food industry, biotechnology, aviation, and space industry.
Based on the analysis of energy consumption and carbon dioxide emissions of the construction industry, it is stated that the reduction of energy consumption in Ukraine is achieved through termomodernization of the existing building stock and build new buildings, which meet energy efficiency requirements. Comparison of thermal parameters of different wall materials are given. It is shown that multilayer wall constructions must be used to ensure the necessary indicators of external walls of energy efficient buildings.
At present, the problem of energy-saving construction remains extremely relevant. The use of alternative energy sources for heat supply of buildings and structures is one of the ways to solve the problem of rational use of fuel and energy resources.
This article considers effective methods of using solar energy with the help of thermosyphon solar collectors integrated into the external enclosing structures of a modular house.
