Решение вопроса сезонности этого вида энергии позволит увеличить объёмы выработки энергии и достичь нулевого углеродного следа для энергоэффективных зданий.ЗНАЧИМОСТЬ. Впервые на экспериментальном уровне оценены реальные режимы работы подземного теплового аккумулятора в сочетании с плоскими солнечными коллекторами в условиях длительного холодного периода. Определен температурный предел безопасной эксплуатации теплового аккумулятора (ТА) с теплоизоляцией из XPS (83,7°C), что позволяет повысить надежность проектирования. Полученные данные использованы для адаптации и уточнения математических моделей в TRNSYS, что повышает точность прогнозирования работы системы. Практическая значимость: достижение снижения энергопотребления на отопление и ГВС до 42% по сравнению с исходным уровнем. Увеличение периода работы отопительной системы без включения теплового насоса – до 20 декабря 2024 года. Подтверждение достижимости нулевого углеродного следа для жилого дома. Возможность применения результатов при проектировании энергоэффективных зданий в условиях холодного климата.МЕТОДЫ. Экспериментальные измерения температур и энергопотребления оборудования в 2022- 2024 гг. Математическое моделирование тепловых процессов: ANSYS Steady State Thermal – определение максимальной безопасной температуры ТА. TRNSYS – прогнозирование работы системы в зимний период.РЕЗУЛЬТАТЫ. В результате проведенных экспериментальных и расчетных исследований были осуществлены анализ и оценка данных мониторинга выработки и потребления тепловой энергии. Потребление электрической энергии на отопление и горячее водоснабжение дома за счет использования теплового насоса и солнечных коллекторов снизилось с 4420 кВт·ч в 2022 году до 3050 кВт·ч в 2023 году, т.е. на 31%, а в 2024 году снизилось до 2568 кВт·ч, т.е. на 42%.ЗАКЛЮЧЕНИЕ. Использование сезонного подземного теплового аккумулятора и солнечных коллекторов для отопления и ГВС, в сочетании с фотоэлектрическими панелями и электрозарядкой для автомобиля, обеспечило достижение нулевого углеродного следа в 2023 и 2024 гг.</p></abstract><trans-abstract xml:lang="en"><p>THE PURPOSE of this paper is to analyze the efficiency of a seasonal UTES for heating a residential building and optimize its operational modes based on experimental data from 2022-2024. Addressing the seasonality of this energy source will increase energy generation and achieve net-zero carbon for energy-efficient buildings.SIGNIFICANCE. For the first time, the actual operating modes of UTES in combination with flat-plate solar collectors have been experimentally assessed under conditions of a long cold period. The temperature limit for safe operation of the UTES with XPS thermal insulation (83.7°C) has been determined, which allows for increased design reliability. The data obtained has been used to adapt and refine mathematical models in TRNSYS, improving the accuracy of system operation prediction. Practical significance: achieving a reduction in energy consumption for heating and hot water supply of up to 42% compared to the baseline. Extension of the heating system operation period without turning on the heat pump – until December 20, 2024. Confirmation of the achievability of net-zero carbon for individual building. Potential application of the results in the design of energy-efficient buildings in cold climates.METHODS. Experimental measurements of equipment temperatures and energy consumption in 2022-2024. Mathematical modeling of thermal processes: ANSYS Steady State Thermal – determination of the maximum safe temperature of the heating system. TRNSYS – forecasting system performance in winter.RESULTS. The experimental and computational study enabled comprehensive analysis and evaluation of thermal energy production and consumption monitoring data The integrated heat pump and solar collector installation yielded substantial energy conservation: Electricity consumption for the heat supply system of building, thanks to the use of a heat pump and solar collectors, decreased from 4420 kWh in 2022 to 3050 kWh in 2023, i.e. by 31%, and in 2024 decreased to 2568 kWh, i.e. by 42%.CONCLUSION. The use of a UTES and solar collectors for the heat supply system, in combination with photovoltaic panels and electric car charging, ensured the achievement net-zero carbon in 2023 and 2024.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энергоэффективность</kwd><kwd>тепловой насос</kwd><kwd>возобновляемые источники энергии</kwd><kwd>сезонный подземный тепловой аккумулятор</kwd><kwd>солнечный коллектор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>energy efficiency</kwd><kwd>heat pump</kwd><kwd>renewable energy</kwd><kwd>seasonal underground thermal energy storage</kwd><kwd>solar collector</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sultanguzin I.A., Kalyakin I.D., Govorin A.V., Khristenko B.A., Yavorovsky Y.V., “Optimization of the energy efficient active house”, in Digests of Conference 3.
