Abstract

Рассмотрены вопросы комплексного подхода снижения энергопотребления в системах теплоснабжения зданий. Предложены режимы прерывистого отопления в общественных зданиях. Представлена схема комбинированного теплоснабжения с использованием теплового насоса и газового котла. Проведено моделирование режимов работы системы теплоснабжения здания с использованием тепловых насосов и прерывистого отопления. Предложены рекомендации по использованию традиционных и возобновляемых источников тепла в комбинированной системы теплоснабжения. Показана экономия от применения режима прерывистого отопления для общественных помещений.Against a background of an abrupt increase in utility prices in Ukraine a problem of the saving of energy resources and the search for energy saving technologies for heat supply systems becomes a burning issue. The heat supply systems of public buildings with the double-period operation mode, in particular working and standby conditions provoke a keen interest. This paper gives consideration to the issues of the integrated approach to the reduction of the energy consumption by the heat supply systems of the buildings. The issues related to the use of renewable heat sources for combined heat supply systems were touched upon. The factors that affect the use of thermal pumps with the heat source, in particular the open air in heat supply systems have been analyzed. A circuit diagram for combined heat supply to training buildings of the university using the thermal pump and a gas condensation boiler has been developed. Intermittent heating conditions for the public buildings were proposed. The operation modes of the heat supply system of a building using thermal pumps and the intermittent heating were simulated. The recommendations on the use of traditional and renewable heat sources in combined heat supply systems were given. The saving efficiency due to the use of intermittent heating mode for public buildings was shown
