В качестве способа снижения температуры обратной сетевой воды предложено использование абсорбционных трансформаторов теплоты (АТТ) на центральных тепловых пунктах (ЦТП), функционирующих по циклу абсорбционного теплообменника.  В качестве критерия оценки выбран эксергетический коэффициент полезного действия, поскольку он, учитывая разнородность видов энергии в системе, позволяет выполнить как относительную, так и абсолютную оценку степени термодинамической эффективности, а также учитывает потери от неравновесности процессов в системе. Приведены результаты многопараметрического анализа АТТ, полученные на основе разработанной математической модели, достоверность которой проверена экспериментально. При анализе системы теплоснабжения учитывается влияние температуры обратной сетевой воды на расходы теплоносителей и энергозатраты на привод циркуляционных насосов в тепловой сети и насосов в сети потребителя. В формулу для определения эксергетического КПД ТЭЦ вводятся дополнительные составляющие. Приводится сравнение традиционной системы теплоснабжения с ЦТП и новой системы с абсорбционным трансформатором АТТ (ЦТП) для различных температур сетевой воды в подающей линии. Для сравнения используется метод относительного соответствия, предложенный В.П.Мотулевичем. Анализируются результаты по следующим контурам системы теплоснабжения: Источник-АТТ (ЦТП), Источник-Потребитель.  В контуре Источник-Потребитель показано значительное увеличение эксергетического КПД в новой системе при достаточно высокой температуре сетевой воды в подающей линии, что связано с изменением энергозатрат на привод циркуляционных насосов и приростом мощности электрогенератора. В роли источника выбран турбоагрегат Т-100-130 ТМЗ.</p></abstract><trans-abstract xml:lang="en"><p>The questions of evaluation of energy efficiency of municipal heating and electric power supply systems based on the combined heat and power supply plant (CHPP) with a reduced temperature of return delivery water are considered in the paper. As a method of reducing the return delivery water temperature, using heat absorption transformers (HAT) at central heat supply stations operating as absorption heat-exchange facility was considered. The exergetic efficiency was chosen as an evaluation criterion, because, given the difference in kinds of energy in the system, it allows to perform both relative and absolute estimates of thermodynamic effectiveness as well as takes into account the losses from non-equilibrium of processes in the system. Results are given of HAT multiparameter analysis that were obtained on the basis of a developed mathematical model, the reliability of which was experimentally tested. During analysis of the heat supply system, one should take into account the influence of return delivery water temperature on consumption of heat-transfer agents and power consumptions on driving the recycling pumps in the heating network and pumps in the consumer network. Additional components are inntroduced into the equation for determining the exergetic efficiency of CHPP. The traditional heat supply system is compared to the central heat supply station and the new system with an absorption transformer AT (central heat supply station) for different temperatures of delivery water in the flow line. The relative correspondence method proposed by V. P. Motulevich was used for the comparative analysis. The results are analyzed by the following lines of the heat supply system: Source-AT (central heat supply station), SourceConsumer. In the Source-Consumer line, a considerable increase is shown of exergetic efficiency in the new system at a rather high temperature of delivery water in the flow line. This is due to variation of power consumption on driving the recycling pumps and the generator unit capacity gains. Turbine-generator set T-100-130TMZ is selected as a source.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>система теплоснабжения</kwd><kwd>энергозатраты</kwd><kwd>ТЭЦ</kwd><kwd>абсорбционный трансформатор теплоты</kwd><kwd>абсорбционный теплообменник</kwd><kwd>эксергетический КПД</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heat supply system</kwd><kwd>power consumption</kwd><kwd>CHPP</kwd><kwd>absorption heat transformer</kwd><kwd>absorption heat exchanger</kwd><kwd>exergetic efficiency</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ, проект №17-08-00984 A (договор 17-08-00984/18 от 27.02.2018)</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">Мирасова Л.
