Энергоэффективное управление системой отопления для зданий с циклическим режимом работы

Abstract

Lack of energy can be a significant factor holding back the country's economic growth. At the level of objects of energy consumption, this problem can be solved by developing systems for energy efficient management 
 of the consumption of energy resources, taking into account the peculiarities of the functioning of specific objects. There is considered a heating system of the building of the OSTROVskiy shopping center (SC) (Astrakhan). There has been made engineering evaluation analysis of energy saving and energy efficiency measures of the building. Engineering evaluation analysis of the building and the heating system of the SC as a control object was carried out, the main regulated, regulating and disturbing quantities were identified. A functional model of a SC as a thermal facility has been developed. To calculate the air temperature inside the building, a thermal model of the object was built based on the thermal characteristics of the building envelope. The correspondence of the model to the real thermal characteristics of the building is shown. A control system for the heating point of SC was developed using the Totally Integrated Automation Portal software. The interface of the control and management system for the heating point of SC has been developed. An algorithm for the heating system functioning in an energy-efficient mode is proposed, taking into account the cyclical mode of operation of SC. A comparative evaluation of the effectiveness of the proposed control system for a thermal substation in the modes of constant performance, variable performance with manual control, variable performance with automatic energy-efficient control has been carried out. It is shown that the use of the proposed method of energy efficient control makes it possible to reduce the consumption of thermal energy by 21.7% compared to the constant performance option used.
