Article is devoted to increasing efficiency of heat supply systems. We demonstrate research results and an analysis of dependences of overall heat supply system performance indicators at various levels of equipment of consumers with the automated individual heating substations.
Abstract. Introduction of the automated metering stations and regulation (AUU) located directly in the heated building besides creation of comfortable conditions indoors leads to decrease in consumption of thermal energy. The annual expected effect of realization of the offered actions (installation of metering stations and automatic control) can make up to 22% consumed and that isn't less important, the paid thermal energy. In general, efficiency of implementation of the project on introduction of AUU can be characterized by considerable decrease in heat consumption of the building and, respectively, reduction of a payment for the consumed energy resources. In this paper we evaluated the effectiveness of implementation of increase of energy efficiency of the building investment project (hereinafter SP). We calculated the ratio of expenses and the results considered actions for inhabitants of an apartment house located in Kazan after installation of a weather-dependent regulation. As a result of calculation of the imitating model created on the basis of basic data and the investment project plan the main results of determination of economic efficiency of the Project have been received. For the analysis and increase of reliability of a settlement assessment of efficiency of the investment project calculations at different options of a set of basic data are executed.
In this work results of mathematical modeling and results of the pilot studies conducted at the laboratory stand for the system of heat supply of Kazan, the development of power of the large cities directed to development of an integrated approach at a research of problems are integrated. By means of the program Zulu complex the mathematical model intended for optimization of work of power systems during their operation has been created.Results of the conducted researches have allowed to analyse influence of stage-by-stage introduction at consumers of automatic metering stations and weather regulation (AITP) on a hydraulic operating mode of system of heat supply for large municipal associations. In this work the main criteria are also considered, the algorithm and a method of calculation of power efficiency is developed by optimization of systems of municipal heat supply by introduction of the automated individual thermal points (AITP). The questions of influence of the made technical solutions on financial and economic and investment indicators are raised. The considered actions for energy resources saving are investigated for the purpose of reduction of volumes of consumption or more rational use of fuel and energy resources.
