The climatic features of the Murmansk region (low average annual temperature; insignificant number of sunny days) do not contribute to the effective use of natural methods of drying aquatic organisms and determine the use of artificial dehydration methods using appropriate equipment. The capabilities of ship fish processing complexes are limited; highly productive coastal fish processing plants are required to supply the population with fish products. The development and testing of new drying modes has been carried out using a small-sized drying unit UPOR-M2. In the course of the study, a drying unit modernization project has been developed, equipment has been selected (thermal imaging system; damper and fan control modules), the system has been modernized and a number of experiments has been conducted to determine the effectiveness of the work performed. The modernization of the drying unit has made it possible to increase the accuracy of the data obtained by 25 % (temperature), 20 % (relative humidity), 18 % (weight), to implement remote control of the processes and to ensure reliable operation of the drying system. Further research of different drying modes for aquatic organisms should include upgrading the air supply control system and improving communication equipment.

The problems of ensuring the safety of operation of nuclear power plants are always paid increased attention. In addition to the self-contained diesel generator sets used to maintain the operation of safety systems in case of loss of external power supply, it is also advisable to consider the use of more environmentally friendly self-contained photovoltaic units at this stage. The work is aimed at a comparative experimental study of the efficiency of water cooling in real natural climatic conditions of Southern Russia. In this experiment, cooled and uncooled photovoltaic modules are simultaneously exposed to a complex of variable weather factors: solar radiation, cloudiness, wind, pressure, temperature and humidity of the environment. Both modules have loads connected via MPPT controllers. The effect of water cooling on the energy efficiency of photovoltaic modules assembled from silicon heterojunction technology (HJT) solar cells was studied. The solar panels were made from 130 micron thick HJT cells interconnected using SmartWire contact technology. It reduces power loss due to possible defects such as cracks. The conditions for ensuring the highest degree of similarity between the parameters of the cooled and uncooled modules have been met. A comparative experimental study was conducted in Astrakhan State University using a long-term monitoring system for the characteristics of photovoltaic modules. This is a test photovoltaic system (TPS), built on the basis of the Paragraph PL2 electronic recorder. A significant increase in module output when working with cooling was established. At insolation of 987.5 W/m2, the power generated by the cooled module was 93.0297 W, while the power of the module without cooling was 79.306 W. The difference comprised 13.7237 watts. Power increased by 17%. In the experiment, the average efficiency value when the module was cooled was 0.15977. When uncooled, it was 0.13764. The efficiency intensified by 2.21%. This increase is significant. The results obtained confirm the fairly high efficiency of water cooling in photovoltaic modules in real natural operating conditions for regions with high ambient temperatures, Southern Russia, in particular

Renewable energy is a type of energy that can be used continuously regardless of the source that can be consumed as it is used. Renewable energy is derived from "natural resources" that can be continuously or repeatedly extracted from the natural environment. Since these resources are self-existent and inexhaustible over time, they take their place in our lives as alternative energy. Today, the world energy industry is influenced by new global trends and tendencies, which cause changes in market structure, increased competition at sectoral and intersectoral levels, and dynamic growth in innovative technologies in energy production. This article highlights the important features of sustainable energy supply in Azerbaijan. Unlike other countries, Azerbaijan has enough reserve resources to meet its energy needs. However, the recovered energy sources in Lankaran-Astara economic region are not widely spread. Nevertheless, this region has potential profitable recovered energy sources such as solar energy, small river and stream energy, wind energy, geothermal water energy, and biomass energy, and significant work needs to be carried out in the relevant field in the future. Purpose: The purpose of the article is to emphasize the problems related to energy efficiency and to highlight scientific innovations related to the application of sustainable energy sources necessary for modern development. Methodology: The article is based on energy efficiency problems and related experiences that are necessary for sustainable development. It is prepared by using research conducted by many states and international organizations and various scientific sources. Scientific novelty: The article focuses on energy efficiency issues. The latest innovations such as the application of innovative technologies in the energy sector and the efficient use of sustainable energy sources are discussed. [ABSTRACT FROM AUTHOR]

Updating the development of specific electrical loads of residential buildings of clusters 1 (up to 5 floors) and 2 (6–11 floors) based on actual measurements (with amendments to the Code of Rules 256.1325800.2016 "Electrical installations of residential and public buildings. Design and installation rules") contributes reducing the cost of technological connection in residential construction, as well as reducing the actual unused "locked power" at the same time as reducing electricity losses in power transformers. In the course of the study, an analysis has been made of the actual electrical loads of residential buildings in Moscow for the periods from November 1 to November 30, 2021 and from December 25, 2021 to January 31, 2022. The number of the studied sample for cluster 1 is 91 houses, for cluster 2 – 58 houses. When determining the maximum specific power of a sample set of multi-apartment residential buildings in Moscow in clusters 1 and 2, an average value and a confidence interval have been established, which "covers" the average of the general population with a probability of 95 %; a comparative analysis of the actual specific electrical loads of a residential building with the loads given in the Code of Rules has been carried out. Based on the results of statistical processing of a sample of multi-apartment buildings in clusters 1 and 2, the dependence of the maximum specific power on the number of apartments in a residential building has been determined with a trend line that clearly illustrates the trend in the studied dependence.

Важность задачи энергосбережения в строительном секторе определяется значительной долей первичной энер­гии, потребляемой в ходе строительного производства и эксплуатации объектов капитального строительства. Энергетическая эффективность жизненного цикла объекта капитального строительства определяется геометрическими и теплофизическими характеристиками ограждающих конструкций. Особую роль в достижении энергоэффективности играют объёмно-планировочные решения. Проанализированы зарубежные проекты купольных зданий середины ХХ века, запроектированные такими архитектора­ми, как Ричардом Бакминстером Фуллером, Николасом Гримшоу, архитекторами Мерфи и Макки, Эберхардом Генрих Зейдлером и другими. В результате работы определена зависимость коэффициента компактности здания, имеющего форму шарового сегмента, от радиуса купольной части и высоты, рассчитаны мощности тепловых потерь через поверхности ограждающих конструкций, линейные и точечные теплонапряжённые элементы, определены полные потери тепловой энергии за отопительный период через ограждающие конструкции зданий, имеющих форму шарового сегмента, а также сформулированы методы энергетической оптимизации объёмно-планировочных решений таких зданий. Выявлено, что при увеличении коэффициента компактности воз­растает расход ресурсов на изготовление и монтаж ограждающих конструкций и уменьшается энергоэффективность здания[1].

The question of the relationship between the processes of modernization and the development of energy in Sweden and England in modern times is considered. The author investigates the problem of regional features of early industrialization in these countries. A review of modern English-language historiography on this topic is carried out. The author’s development of a model of the synergetic relationship of energy consumption, energy efficiency and economic growth in the 18th—19th centuries is presented. The question is raised about the typological similarity of the processes of economic and technological development of Sweden and England in modern times in the context of the capitalist world-system. At the same time, it is shown how the specific natural and socio-economic conditions in these countries influenced the historically determined differences in the use of firewood, coal, steam engines. Particular attention is paid to such factors of Sweden’s development as the early nature of proto-industrialization processes and the country’s semi-peripheral position in the capitalist world-economy. The author reveals the logical connection between the key positions of England in the international system of production and exchange and the dynamic introduction of new energy sources in modern times. It was concluded that factors related to the position of a particular country in the system of center-peripheral relations were of decisive importance for economic growth and energy.

It is frequently believed that electric cars are an important means of reducing greenhouse gas emissions and energy consumption in global transport, especially for passenger automobile transport. The purpose of this paper is to study the relative energy usage and greenhouse gas emissions of electric vehicles compared to cars with an internal combustion engine. A comparison of energy efficiency as well as a comparison of greenhouse gas emissions were used as methods in this paper. Energy efficiency comparisons are complicated by conflicting methods used for primary sources of electricity, such as hydro, solar, or wind. This paper reviews the extent to which electric cars can effectively address global climate change and fossil fuel depletion. Moreover, the paper proves that comparing electric vehicles and vehicles with an internal combustion engine is much more complicated than generally accepted. Uncertainties arise both when using primary energy and when calculating greenhouse gas emissions. In general, it must be concluded that the benefits of using electric vehicles for energy and greenhouse gases are less than usually expected. Only when renewable energy prevails in interconnected energy systems, it will be safe to claim the superiority of electric vehicles.

This article presents the value of further increase of the energy efficiency in railway transport in combination with transition to the non-standard sources of energy. This is done within the paradigm of sustainable development and decarbonization in the global economy and by also taking into account the objectives stated in the document “Global perspective of railway transport development until 2050.” Hydrogen fuel cells, which are being studied by the Technical and Scientific Council of the JSC “RZD”, have demonstrated to be the most beneficial. The global trends of commercial use of fuel cells for transport are based on the unique properties of hydrogen as a fuel: high energy efficiency, ecological safety, and capability to be used without electric grids. Taking into account technological and ecological value, the transition from diesel traction to hydrogen fuel cell traction is justified and can be evaluated as a step of evolution that is as valuable as the transition from steam traction to diesel traction. Empirical proof is available that hydrogen is not hazardous to handle with properly designed equipment. The potential of the Russian science allows fulfilling appropriate research and development. We have taken into account that the required scientific and technological competences are available in different scientific centers and their effective integration is required. The conclusion states that the required conditions exist for introduction of the hydrogen fuel cells to the rolling stock in Russia. Although manufacturing of the critical fuel cells is not currently available in the Russian Federation, it can be arranged if demand is sufficient. This will require the collaboration of customers and scientific investigators in the project development of electric rolling stock in which hydrogen fuel cells can be used.

Предмет. На сегодняшний день в экономике Российской Федерации, и в частности на уровне промышленных предприятий, перфоманс-контракты в части модернизации и управления основ- ными средствами практически не применяются. Весь опыт развития перфоманс-контрактинга в России напрямую связан с энергосервисными контрактами. Вместе с тем имеющийся потенциал по сокращению энергопотребления и повышению энергоэффективности даёт возможность использовать механизм перфоманс-контрактинга в России уже сегодня. Успешное развитие перфо- манс-контрактинга в энергетической сфере позволяет сделать обоснованный вывод о возможно- сти его использования и в других неэнергетических отраслях, например, в процессе управления основными средствами промышленных предприятий. В основе предлагаемого подхода к использованию перфоманс-контрактинга в управлении основными фондами промышленных предприятий лежит идея о том, что исполнитель по такому контракту берёт на себя все риски внедрения новых объектов основных средств в реальных производствах. Цель исследования состоит в проведении анализа проблем развития перфоманс-контрактинга в России и выработке рекомендаций по его развитию. Методология. В процессе достижения поставленных целей использовались методы научного познания: диалектический; анализа и синтеза. Исследование построено на изучении актуальной научной и периодической экономической литературы. Результаты. Приведена краткая история становления и развития энергосервисных контрактов. Отражены основные статистические данные, характеризующие развитие рынка перфоманс-кон- трактинга в России на современном этапе. Выводы. На основе проведенного исследования обоснована необходимость использования перфоманс-контрактинга в управлении основными средствами промышленных предприятий. В заключительной части статьи представлены основные причины, препятствующие массовому развитию перфоманс-контрактинга в России, а также предложены некоторые рекомендации для его развития. Обоснован вывод о необходимости продолжения работы по внедрению механизмов стимулирования промышленных предприятий в области применения перфоманс-контрактов для финансирования проектов и мероприятий по обновлению и модернизации основных фондов, а также повышению их энергоэффективности, что позволит осуществлять привлечение новых инвестиций в энергосбережение и обеспечит возврат инвестированных средств за счет экономии финансовых ресурсов.

Purpose. The main purpose of the study is to create energy-efficient solutions when designing the lighting of the entrance group for the case when the object must provide round-the-clock operation Methodology. To achieve this goal, a method for multi-level connection of light sources of different intensities has been developed. The control of the processes of level regulation is carried out using motion sensors. Results. The modern level of LED products makes it possible to use LED lighting sources as universal ones, allowing you to implement any design solution. The introduction of motion sensors as elements for regulating the intensity of light allows to obtain more than 50% energy savings. Interesting design solutions help create light accents without creating too much lighting on certain objects. Scientific novelty. The work combines multilevel lighting systems using motion sensors as switches operating at night. The authors proposed a sequence of connecting the levels of the system to create the most comfortable stay and a good first impression of the institution. Such a system makes it possible to use lighting not only for practical purposes, but also for the most attractive visual appearance. Practical significance. The versatility of this methodology allows it to be applied to objects of various purposes, including round-the-clock service. However, it is important to plan for such a lighting system even at the design stage of the building in order to obtain the maximum economic benefit. [ABSTRACT FROM AUTHOR]

На основе предложенного геоэнергетического подхода проведена оценка энергоэффективности лесного хозяйства и экосистем Приднестровской Молдавской Республики. Основу модели устойчивого развития лесной экосистемы Приднестровья составляет энергоэффективная технология лесовосстановления. Исследования проводились в урочище Калагур. Описана технология лесовосстановления, где применение механизации минимальное, а использование лесной среды материнских насаждений максимальное. Энергоёмкость предложенной технологии в несколько раз меньше по сравнению с другими технологиями лесовосстановления в ПМР. Эта технология позволяет повысить энергопотенциал леса, создать высокопродуктивные лесные массивы, ценные с экономической и экологической точек зрения. В перспективной энергосберегающей модели лесовосстановления с минимальным использованием средств механизации и других видов работ получается экономия энергоресурсов и сохраняется биоразнообразие природных систем.

Промышленное производство Республики Беларусь относится к высокотехнологичным и энергоемким отраслям. Наибольший вклад в производство промышленной продукции вносят машиностроительный и металлообрабатывающий комплекс (19,3%), а также химическая и нефтехимическая промышленность (12%). В структуре конечного энергопотребления на промышленность приходится до 50% топливно-энергетических ресурсов, импорт которых составляет до 85%. Оценка суммарного количества низкопотенциальной тепловой энергии, обращающейся на наиболее крупных предприятиях Беларуси, составляет порядка 1200 МВт, что сопоставимо с мощностью одного энергоблока строящейся Белорусской АЭС. Приведенные цифры свидетельствуют об огромном потенциале применения технологий рекуперации низкопотенциального тепла, в первую очередь на промышленных производствах. Одним из решений является предлагаемый компрессионный тепловой насос, отличающийся тем, что в нем используется доступное, недорогое и безопасное рабочее тело – смесь паров воды и воздуха, в качестве теплообменника-испарителя – струйный аппарат, а в качестве компрессора – ротационно-пластинчатый вакуум-насос. При оценке технико-экономических показателей от внедрения рассматриваемого паровоздушного теплового насоса на технологической установке ОАО "НАФТАН» для рекуперации низкопотенциального тепла оборотной воды системы охлаждения технологического оборудования установлено, что при его круглогодичном применении срок окупаемости составит ~3,7 года.

Микроклимат помещений формируется под воздействием процессов теплообмена с внешней средой через наружные ограждения, режимом отопления, внутренними теплопоступлениями и другими факторами. При эксплуатации зданий со временем строительные материалы могут разрушаться, изменяя свои теплотехнические свойства. Основным направлением сокращения расходов на отопление является увеличение теплового сопротивления ограждающих конструкций путем их утепления. Исследование теплозащитных свойств, сопоставление фактических и расчетных значений термических сопротивлений наружных ограждающих конструкций кирпичного здания САФУ до и после утепления является актуальной задачей с точки зрения энергосбережения. Оценка тепловой защиты и энергетической эффективности кирпичного здания САФУ была выполнена расчетным путем и инструментальным измерением в натурных условиях. В работе представлены результаты пятилетнего исследования ограждающих конструкций кирпичного здания САФУ постройки первой половины прошлого века, которые подверглись реконструкции. Приведены расчетные и фактические термические сопротивления ограждающих конструкций до и после утепления, проведено их сравнение с нормативными значениями по санитарно-гигиеническим требованиям и из условий энергосбережения. Эксперименты подтвердили сходимость расчетных и фактических значений термического сопротивления наружной стены во всех случаях инструментальных замеров. В результате проведенной реконструкции был достигнут класс энергоэффективности здания «В».

The choice of the method of basic cultivation must be differentiated, considering zonal soil and climatic conditions and local peculiarities of the fields. Chisel tillage refers to soil conservation technologies, and chisel tools provide low-power and, if it is necessary, differential loosened soil, the accumulation, preservation and rational use of soil moisture that is relevant in the arid climate. The authors designed the combined chisel working implements RANCHO, ROPA, plow-cultivator. The traction resistances of the working tools were studied strain-gauge method. The unified equation of traction resistance chisel working was developed. The resistance of tine, chisel, additional equipment on the tine and the dynamics of the chiseling were introduced. The resistance of the chisel was determind by pressure from the soil on its surface. If the speed of machine-tractor aggregate will increase from 1 to 3 m/s then traction resistance of the working implements ROPA will rise by 26-29 percent, plow-cultivator - by 21-23 and classic mould-board plough - by 35 percent due to more significant influence of the dynamic component during moving mould-board plough in the undisturbed soil. The plowing work by the plow-cultivator in comparison with mould-board plough provides more depth of soil loosening (0.38 m when 0.15 m real tillage and 0.2 m in control variant) at comparable energy consumption.

The article considers the problems of enhancing the structure of power and heat generation in Russia, Siberia and the Novosibirsk region. It is shown that the synchronization of energy and heat supply schemes through the development of the distributed power generation (including the cogeneration installations) should become a priority task of the power generation development. Integration of the power generation at the municipal level into the development plans for big power industry and the transition to a new cogeneration paradigm allows to significantly improve the efficiency of both production and consumption of energy. The carried-out serial calculations for a comparative assessment of a number of technologies of the small-scale distributed power generation in the Novosibirsk region allowed to select the perspective directions of diversification of energy sector and to reveal the variety of types and forms of interaction between big and small-scale distributed power generation facilities.

Development of the hybrid control system of the energy saving drive of the single-bucket rotary platform of the excavator

In carrying out the most energy-intensive operations (introduction of the bucket into the ground and peel shavings) on the working of the excavator body are alternating loads, causing the tension elements of the bucket and the working equipment. Reliability and availability of the excavator and the energy intensity of the workflow depends on the validity of the acceptable values of loads and redistribution of the elements of the work equipment taking into account the safety factor. The article substantiates the relevance and perspective shovel energy research. According to the research the technique of experimental studies, combined with simulation modeling shovel loading conditions.

Technological capabilities such digger is the excavator, depend on the power of the power plant, the type of work equipment, bucket capacity and drive systems. Performance indicators are excavator productivity, efficiency hydraulic drive expended power per unit volume of soil being developed, cost, minimal cycle times and state of the hydraulic drive. The article presents the results of the hydraulic drive of the internal energy research, which has been interpreted through an understanding of the power distribution principle of the hydraulic drive and the power plant. Established the most energy-intensive operation, causing overvoltage elements of the power plant and the hydraulic drive. Proposed the scientific concept of energy efficiency increase shovel capacity through redistribution allowed to expand the knowledge base in the field of efficiency of operation of earthmoving machinery.

The current stage of development of processes of modeling systems characterized by an increase of functional saturation. Modeling work processes excavator hydraulic drive is a complex hierarchical task, as in the performance of technological operations of the excavator is necessary to record and analyze a large number of factors and parameters, dynamically changing over time.
