Данная модель нестационарного теплообмена позволяет для различных климатических условий, типов гелиотехнического оборудования, типов систем отопления здания определить площадь и количество солнечных коллекторов и объем сезонного (грунтового) аккумулятора теплоты, обеспечивающих необходимые температурные характеристики здания. Для свойственного в условиях резкоконтинентального климата сезонного изменения приходов солнечной радиации и температуры окружающей среды получены аналитические выражения и выполнено численное исследование времени использования аккумулированной энергии для здания отапливаемой площадью 70 м2 . Показано, что при объеме грунтового аккумулятора тепла 500 м3 и максимальной температуре нагрева 90 ºС запасенной энергии достаточно для обогрева здания системой «теплый пол» более чем на 100 суток. Представлены данные, подтверждающие целесообразность применения солнечных систем теплоснабжения с грунтовым аккумулятором теплоты для суровых климатических условий, характерных для Уральского федерального округа России. Использование грунтовых аккумуляторов теплоты является простым и малозатратным способом переноса во времени (с летнего на зимний период) энергии солнечного излучения, что позволяет существенно сократить затраты органического топлива на обогрев помещений в отопительный период. Наибольшая эффективность использования аккумулированной в грунте энергии достигается благодаря низкотемпературным системам обогрева (теплый пол, воздушное отопление). Представленная методика является достаточно универсальной и может применяться для любых грунтов и накопительных сред, отличающихся от естественного грунта теплофизическими характеристиками (талькохлорит, талькомагнезит, солевые композиции и пр.), а также для других типов тепловых нагрузок, в том числе, для поддержания благоприятного температурного режима в плавательных бассейнах и сельскохозяйственных сооружениях закрытого грунта и пр.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of the development of a methodology for a comprehensive assessment of the system's efficiency, which includes solar collectors, a heat storage tank, a ground heat accumulator, and a building heating system. The model of non-stationary heat exchange makes it possible to determine the area and the number of solar collectors and the volume of a seasonal (ground) heat accumulator for various climatic conditions, types of solar engineering equipment, types of heating systems in the building, providing the necessary temperature characteristics of the building. We have obtained analytical expressions for a seasonal change in solar radiation and ambient temperatures typical for a sharply continental climate, and have made a numerical study of the time of use of the accumulated energy for a building with a heated area of 70 m2 . For a 500 m3 ground heat accumulator with a maximum heating temperature (90 °C), the stored energy is shown to be sufficient for heating the building with a warm floor system for more than 100 days. The paper submits the data confirming expediency of use of solar systems of heat supply with the ground heat accumulator for the severe climatic conditions characteristic of the Ural region of Russia. The use of ground heat accumulators is a simple and low-cost method of transferring solar energy in time (from summer to winter), which allows us to significantly reduce the cost of organic fuel for heating the premises during the heating season. The greatest efficiency of use of the energy accumulated in the ground is achieved when applying low temperature heating systems (underfloor heating, air heating). This technique is quite universal and can be used for any grounds and accumulative environments that differ from the natural ground by thermal physical characteristics (talcochlorite, talcomagnesite, salt compositions, etc.), as well as for other types of thermal loads, such as maintaining a favorable temperature regime in swimming pools and agricultural structures of enclosed soil.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гелиосистема</kwd><kwd>грунтовый аккумулятор</kwd><kwd>теплопроизводительность</kwd><kwd>система хранения энергии</kwd><kwd>солнечная радиация</kwd><kwd>частные дома</kwd><kwd>резкоконтинентальный климат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>solar system</kwd><kwd>seasonal heat accumulator</kwd><kwd>heat performance</kwd><kwd>energy storage</kwd><kwd>solar radiation</kwd><kwd>private houses</kwd><kwd>sharply continental climate</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">Kuravi, S.
