Анализ осуществлен на основании распределений температуры поверхности, конвективного коэффициента теплообмена, удельного конвективного и удельного радиационного потоков. Разработанная двумерная физико-математическая модель учитывает сложный сопряженный теплообмен в ограждающих конструкциях и в свободном пространстве помещений, влияние вида отопительного прибора на процессы переноса. Учитывается конструктивная неоднородность ограждений и заполнения световых проемов. Модель также содержит уравнения радиационного теплообмена между поверхностями внутри помещения, оконными стеклами и окружающей средой. Представлен анализ локальных характеристик теплообмена на внутренних поверхностях окна, нижней части наружной стены, расположенной под окном, и пола. Рассмотрены четыре вида нагревателей: радиатор, конвектор, подоконная отопительная панель и напольное отопление. Выявлена существенная пространственная неоднородность распределения параметров теплообмена на внутренних поверхностях ограждений, обусловленная видом отопительного прибора. Наиболее близкий характер распределений соответствующих величин на поверхности ограждений наблюдается в условиях применения радиатора и конвектора, что определяется значительным сходством полей параметров микроклимата в помещении в этих вариантах. Обнаружены характерные особенности формирования локальных параметров теплообмена на внутренних поверхностях рассмотренных ограждающих конструкций. </p></abstract><trans-abstract xml:lang="en"><p>The investigation of local heat-transfer characteristics on the interior surfaces of the building envelope under natural convection conditions was carried out on the basis of numerical simulation of heat and mass transfer processes in the heated room. The analysis was based on the distributions of surface temperature, convective heat-transfer coefficient, convective heat flux and radiative heat flux. The developed two-dimensional physical and mathematical model takes into account the complex conjugated heat transfer in the building envelopes and indoor free spaces, the influence of heater type on the transfer processes. Constructional irregularities of the structures and the windows are considered. The model also contains the equations of radiative heat transfer between indoor surfaces, window panes and outdoor environment. The publication presents the analysis of the local heat-transfer characteristics on the interior surfaces of the window, the lower part of the external wall located beneath the window, and the floor. Four types of heaters are considered: radiator, convector radiator, wall-radiator under the window and the floor heating. The study reveals considerable heat-transfer parameters spatial nonuniformity on the interior surfaces of the building envelope conditioned by the type of the heat emitter in use. The radiator and the convector radiator use shows the closest distribution character of the corresponding values on the building envelope surface, the fact predicated upon considerable similarity of the indoor-microclimate parameter fields in these variants. The characteristic features of the heat-transfer local parameters forming on the interior surfaces of the considered enclosing structures were discovered. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>численное моделирование</kwd><kwd>теплообмен</kwd><kwd>помещение</kwd><kwd>ограждающая конструкция</kwd><kwd>отопительный прибор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>numerical simulation</kwd><kwd>heat transfer</kwd><kwd>room</kwd><kwd>building envelope</kwd><kwd>heat emitter</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">Фокин, К.
