Abstract: | У статті представлені результати теоретичних досліджень досягнення максимального ефекту
при визначенні економічно доцільного рівня теплозахисту будинків. Він повинен бути оптимальним і в теплотехнічному, і в економічному сенсі.
Показником чого виступають зазначені затрати.
Наведено графічні та аналітичні залежності. Результатами досліджень обґрунтовано отримання
максимального ефекту при застосуванні різних теплоізоляційних матеріалів. Мета роботи – підвищити
ефективність енергоощадних заходів, досягнути зниження їхньої вартості за рахунок оптимізації у
співвідношенні вартості теплової енергії та теплоізоляційних матеріалів, визначити критерій
оптимізації та обґрунтувати вибір оптимального теплоізоляційного матеріалу і його товщини та
визначити оптимальний термічний опір, виявити шляхи підвищення ефективності енергоощадності
на перспективу та обґрунтувати методику розрахунку. Розглянуто один із найпоширеніших термореноваційних
заходів, а саме утеплення зовнішніх стін. Проведено економічну оцінку, що є важливим чинником певної
енергоощадної пропозиції. Представлено розв’язок поставленої задачі,
який охоплює дві стадії. Результатом на першій стадії є вибір оптимального матеріалу ізоляції.
Друга стадія – це обґрунтування економічно доцільної товщини теплоізоляційного матеріалу. Отримані
результати дають змогу досягнути підвищення ефективності енергоощадності при термореновації
будинків і в енергетичному, і в економічному аспектах. У цій статті представлено результати
математичного обґрунтування важливості такого чинника як теплопровідна вартість теплоізоляційних матеріалів при оптимізації їхньої товщини. The article presents the results of theoretical research to achieve the maximum effect in determination of the economically feasible level of buildings thermal protection. It must be optimal both thermally and economically, an indicator of which there are the costs. Graphical and analytical dependences are given. The research results substantiate the maximum effect when different thermal insulating materials are used. The aim is to increase the efficiency of energy saving measures, reduce their cost by optimizing the cost of thermal energy and insulating materials, determining the optimization criteria and justification for choice the optimal insulating material and its thickness, and determining the optimal thermal resistance, identifying ways to improve energy efficiency and substantiation of the calculation method. One of the most common thermal renovation measures, namely insulation of external walls, is considered. An economic assessment has been conducted, which is an important factor in a certain energy-saving proposition. The solution of the problem is presented, which includes two stages. The result of the first stage is the selection of the optimal heat-insulating material. The second stage is a substantiation of economically expedient thickness of the heatinsulating material. The obtained results make it possible to increase the efficiency of energy saving in thermal renovation of buildings taking into account both energy and economic aspects. In this paper the results of mathematical provement of such factor importance as the thermally conductive cost of the heat-insulating material at their thickness optimization are presented. Determining for the establishment of the normative thermal resistance in the future is the ratio of the cost of thermal energy to the thermal conductivity of the insulating material. |
