Abstract

Тема выпускной квалификационной работы: «Однофазные тепловые накопители в инженерных сетях». Данная работа посвящена исследованию однофазных тепловых накопителей и возможности их применения в системе отопления жилого многоэтажного здания. Целью исследования являлось повышение энергоэффективности систем теплоснабжения путем установки однофазного теплового накопителя. Задачи, которые решались в ходе исследования: 1. Изучение существующих систем отопления. 2. Построение расчетной модели однофазного теплового накопителя. 3. Оценка энергоэффективности. 4. Сравнение различных теплоаккумулирующих материалов. В результате была представлена расчетная модель однофазного теплового накопителя и перечень исходных данных для неё, а также был приведен пример расчета такого накопителя для определенного многоквартирного здания и проведено сравнение двух теплоаккумулирующих материалов. На основании полученных результатов был сделан выбор в пользу бетона, в качестве телоаккумулирующего материала. Стоит отметить, что до этого вопрос применения однофазных тепловых накопителей в системе отопления для целого здания не рассматривался. Экономическая эффективность при применении таких накопителей достигается за счет заряда по более дешевому тарифу (ночному), и расходу накопленной энергии в оставшееся время суток.

Theme of final qualification work: "Single-phase heating storages in engineering networks." This work is devoted to the study of single-phase heat storage devices and the possibility of their application in the heating system of a residential multi-storey building. The aim of the study was to increase the energy efficiency of heat supply systems by installing a single-phase heat storage. Tasks that were solved during the study: 1. Review of existing heating systems. 2. Construction of a calculation model of a single-phase heat storage. 3. Assessment of energy efficiency. 4. Comparison of various heat storage materials. As a result, a calculation model of a single-phase heat storage device and a list of initial data for it were presented, and was given an example of calculating such a storage device for a certain multi-apartment building and a comparison of two heat-accumulating materials. Based on the results, a choice was made in favor of concrete, as a body-accumulating material. It is worth noting that before that the issue of using single-phase heat storage devices in the heating system for the whole building was not considered. Economic efficiency with the use of such drives is achieved by charging at a cheaper rate (at night), and the consumption of stored energy in the remaining time of the day.
