Разработана методика для определения основных характеристик элементов предлагаемой системы и расчета её суточного энергопотребления. Проведенный расчет показывает, что предложенная система при номинальной холодопроизводительности 10 кВт, при использовании хладагента R404a, позволяет в условиях климата города Шымкент снизить температуру конден-сации до +32,9°C и суточное энергопотребление на 6,5% по сравнению с обыкновенной парокомпрес-сионной холодильной машиной.</p></abstract><trans-abstract xml:lang="en"><p>To reduce the condensation pressure of the refrigerant in the summer, refrigeration system has been developed, in which, during periods of high air temperature, the heat of condensation is removed to the coolant, which was pre-cooled at night due to radiative cooling. A methodology has been developed for determining the main characteristics of the elements of the proposed system and calculating its daily energy consumption. The calculation shows that the proposed system with a nominal refrigerating capacity of 10 kW, using the R404a refrigerant, allows in the climate of the city of Shymkent to reduce the condensation temperature to +32.9°C, and daily energy consumption by 6.5% compared to an ordinary vapor compression refrigeration machine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиационное охлаждение</kwd><kwd>снижение давления конденсации</kwd><kwd>холодильная техника</kwd><kwd>конденсатор жидкостного охлаждения</kwd><kwd>энергосбережение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiative cooling</kwd><kwd>condensing pressure decrease</kwd><kwd>refrigeration</kwd><kwd>liquid-cooled condenser</kwd><kwd>energy saving</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование профинансировано Ко-митетом Науки Министерства Образования и Науки Республики Казахстан (Проект № AP09258901).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>Committee of Science, Ministry of Education and Science of the Republic of Kazakhstan</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">Birangane V.V., Patil A.M., Comparison of Air Cooled and Evaporatively Cooled Refrigerartion Systems – A Review Paper // J.
