В результате происходит интенсификация теплообменных процессов при конденсации водяного пара.</p><p>Проведены экспериментальные исследования по определению влияния модификации теплообменных поверхностей на эффективность работы конденсационного теплообменного аппарата. Модификация осуществлялась путем формирования на теплообменной поверхности пленки поверхностно-активного вещества — октадециламина, вследствие чего происходила гидрофобизация поверхности.</p><p>Для проведения экспериментальных исследований на территории ТЭЦ-16 филиала ПАО «Мосэнерго» в ФГБОУ ВО «НИУ «МЭИ» разработан и изготовлен опытный образец лабораторного теплообменного аппарата. Анализ результатов исследований показал, что модификация теплообменных поверхностей с использованием октадециламина является технологически обоснованным решением для интенсификации теплообменных процессов в конденсационных теплообменных аппаратах. В результате модификации стальных трубок опытного образца лабораторного теплообменного аппарата угол смачивания увеличился с 88° для исходной поверхности до 110°. Переход к капельному режиму конденсации привел к увеличению тепловой мощности опытного образца лабораторного теплообменного аппарата до 61,5% по сравнению с исходной поверхностью при идентичных режимах работы.</p></abstract><trans-abstract xml:lang="en"><p>One of the promising directions for improving the eﬃciency of condensing heat exchangers is the intensiﬁcation of heat transfer through the transition from the traditional ﬁlm mode to the dropwise condensation mode, in which condensate is formed as separate droplets rather than a continuous ﬁlm, which virtually eliminates thermal resistance in the form of a condensate ﬁlm. As a result, heat exchange processes are intensiﬁed during condensation of water vapor.</p><p>In this paper, experimental studies were conducted to determine the eﬀect of modifying heat exchange surfaces on the eﬃciency of a condensing heat exchanger. The modiﬁcation was carried out by forming a ﬁlm of a surfactant, octadecylamine, on the heat exchange surface, resulting in the hydrophobization of the surface.</p><p>A laboratory heat exchanger prototype was developed and manufactured for conducting experimental research on the territory of CHPP-16 of the Mosenergo branch of the Federal State Budgetary Educational Institution of Higher Professional Education NRU MEI. Analysis of the research results has shown that modifying heat exchange surfaces using octadecylamine is a technologically sound solution for intensifying heat exchange processes in condensing heat exchangers. As a result of modifying the steel tubes of the laboratory heat exchanger prototype, the contact angle increased from 88° for the original surface to 110°. The transition to the dropwise condensation mode resulted in an increase in the thermal power of the laboratory heat exchanger prototype up to 61.5% compared to the original surface under identical operating conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теплообменные аппараты</kwd><kwd>конденсация</kwd><kwd>интенсификация теплообмена</kwd><kwd>поверхностно-активное вещество</kwd><kwd>гидрофобная поверхность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heat exchangers</kwd><kwd>condensation</kwd><kwd>intensification of heat exchange</kwd><kwd>surfactant</kwd><kwd>hydrophobic surface</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">Shuxue Xu, Jianhui Niu, Guoyuan Ma, Junfeng Wu, Research on working characteristics of composite two-stage ventilation heat recovery system with heat pipe and heat pump, Energy, Volume 304, 2024, ISSN 0360-5442, https://doi.org/10.1016/j.energy.2024.132130</mixed-citation><mixed-citation xml:lang="en">Shuxue Xu, Jianhui Niu, Guoyuan Ma, Junfeng Wu.
