Исследование проведено на модернизированном экспериментальном стенде «Холодильник-2» с системой цифрового мониторинга, включающей дополнительных 24 датчика DS18B20 и микроконтроллер STM32. Основной целью являлось сравнение поведения установки при внесении объекта с температурой 40, 60 и 80°C после выхода на квазистационарный режим. Проведён анализ температурных кривых, продолжительности переходных процессов и времени выхода на новый стационарный режим. Дополнительно рассмотрены особенности распределения температур внутри морозильной камеры, а также влияние тепловой нагрузки на работу основных элементов цикла. Научная новизна исследования заключается в комплексном рассмотрении переходных процессов, возникающих при резких тепловых воздействиях, с акцентом на их продолжительность и устойчивость системы. Практическая значимость работы связана с возможностью применения полученных результатов для оптимизации режимов эксплуатации холодильных установок, а также для проведения диагностики неисправностей в условиях, приближённых к реальным. В качестве оптимального выбран режим воздействия 60 °C, который обеспечивает баланс между продолжительностью переходного процесса и равномерностью распределения температур.</p></abstract><trans-abstract xml:lang="en"><p>This article presents an assessment of the performance of a vapor-compression refrigeration system under shock thermal load. The study was carried out on a modernized experimental stand «Kholodilnik-2» equipped with a digital monitoring system, including 24 DS18B20 sensors and an STM32 microcontroller. The main objective was to compare the system behavior when introducing an object with temperatures of 40, 60, and 80°C after reaching a quasi-steady-state mode. Temperature curves, transient process duration, and stabilization times were analyzed. Additionally, features of temperature distribution inside the freezer compartment and the influence of thermal load on the main elements of the cycle were examined.The scientific novelty of the study lies in the comprehensive analysis of transient processes occurring under sudden thermal impacts, with a focus on their duration and system stability. The practical significance of the work is related to the possibility of applying the obtained results to optimize the operating modes of refrigeration systems and to diagnose faults under conditions close to real operation. The optimal regime was found at 60°C, which ensures a balance between transient process duration and uniformity of temperature distribution.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>холодильная установка</kwd><kwd>тепловая нагрузка</kwd><kwd>шоковое воздействие</kwd><kwd>температурные кривые</kwd><kwd>переходные процессы</kwd><kwd>холодопроизвводительность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>refrigeration system</kwd><kwd>shock load</kwd><kwd>transient processes</kwd><kwd>temperature monitoring</kwd><kwd>operational stability</kwd><kwd>cold production</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">Yasuda H.
