В данной работе рассматриваются показатели системы охлаждения на основе абсорбционной бромистолитиевой холодильной машины (АБХМ) на солнечной энергии в климатических условиях г. Астрахани. Метод. Для анализа работы системы была разработана и верифицирована новая математическая модель, основанная на данных имитационного моделирования. Адекватность модели была проверена путем сравнения с существующими данными, а также проведены расчеты необходимого количества солнечных коллекторов. Результат. Исследование показало, что эффективность работы АБХМ зависит от режима подачи охлаждающей среды в абсорбер и конденсатор АБХМ. Параллельная подача демонстрирует лучшие результаты по величине теплового коэффициента. Динамика тепловой нагрузки на генератор показала, что солнечная инсоляция напрямую влияет на производительность системы, достигая максимальной эффективности при высоких уровнях солнечной энергии. Вывод. Результаты работы могут быть использованы для разработки и оптимизации систем холодоснабжения в условиях жаркого климата, что способствует более эффективному использованию солнечной энергии и повышению энергоэффективности.</p></abstract><trans-abstract xml:lang="en"><p>Objective. This study examines the performance indicators of a solar-powered lithium bromide absorption chiller (LBAC) in the climate conditions of Astrakhan. Method. A new mathematical model based on simulation data was developed and verified to analyze the system's performance. The model's accuracy was validated by comparing it with existing data, and calculations were performed to determine the required number of solar collectors. Result. The study showed that the efficiency of the LBAC depends on the mode of coolant supply to the absorber and condenser of the LBAC. Parallel supply demonstrated better results in terms of thermal coefficient. The dynamics of the thermal load on the generator showed that solar insolation directly affects system performance, achieving maximum efficiency at high levels of solar energy. Conclusion. The results of this study can be used to design and optimize cooling systems in hot climates, promoting more efficient use of solar energy and enhancing energy efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энергоэффективность</kwd><kwd>моделирование системы холодоснабжения</kwd><kwd>абсорбционная бромистолитиевая холодильная машина</kwd><kwd>солнечная энергия</kwd><kwd>аккумулирование тепловой энергии</kwd><kwd>действительный термодинамический цикл</kwd></kwd-group><kwd-group xml:lang="en"><kwd>energy efficiency</kwd><kwd>refrigeration system modeling</kwd><kwd>lithium bromide absorption refrigeration machine</kwd><kwd>solar energy</kwd><kwd>thermal energy storage</kwd><kwd>actual thermodynamic cycle</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья написана в рамках выполнения научно-исследовательской работы №622295 «Экологически безопасные технологии энергосбережения и повышения эффективности низкотемпературных систем и преобразователей энергии».</funding-statement><funding-statement xml:lang="en">The article was written as part of the research work No. 622295 "Environmentally friendly technologies of energy saving and increasing the efficiency of lowtemperature systems and energy converters".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Li M., Xu C., Hassanien R.H.E., Xu Y., Zhuang B.
