The objective of the research performed by the authors is to identify the role of energy efficient engineering systems and to assure the energy saving and comfortable indoor environment. The choice of supply-exhaust ventilation systems versus cold supply systems with heat recovery are also considered in the article.The authors argue that the most comfortable and efficient heating system is the one composed of heating panels incorporated into enclosing structures of buildings to ensure the radiant temperature on the premises. This system used as a supplementary heating system backing the hot water heating system that has heating panels integrated into enclosing structures makes it possible to limit the solar heat supply into the premises in summer to improve the indoor environment, whereas any heat perceived by the water from the solar radiation may be expediently used for hot water supply purposes. In the summertime, the proposed system may reduce the solar heat supply, if chilled water is supplied into the system by chillers.Besides, the authors remind the audience that the choice of heating, ventilation and cooling systems needs to be made at the initial design stage depending on the purpose of the building and other factors affecting the rational choice of engineering systems. In some cases, zone heating systems or hot air systems are expedient.
Определена роль использования энергоэффективных инженерных систем, позволяющих экономить энергоресурсы и обеспечить комфортные условия в помещениях. При использовании приточно-вытяжных систем вентиляции с утилизацией теплоты удаляемого воздуха уменьшается расход тепловых ресурсов. Использование систем холодоснабжения с утилизацией отводимой теплоты позволяет уменьшить расход тепловых ресурсов на нужды горячего водоснабжения или др. Выбор рациональной системы отопления позволяет обеспечить комфортные условия для человека и экономить тепловые ресурсы за счет уменьшения температуры воздуха внутри отапливаемых помещений.
