Methodology for Planned Improvement of the Quality of Heating in Cities Based on Criteria- Based Assessment of Heat Input Data

Abstract

The existing methods of survey and assessment of the technical condition of pipelines and heating devices in buildings are based on visual signs of physical wear of heating systems. More detailed survey methods are labor-intensive to implement and do not allow to objectively establish the priority of major repairs of heating systems with the funds allocated for these needs. The article substantiates a more efficient and less expensive method of step-by-step assessment of the technical condition of building heating systems. The proposed method is based on the analysis of currently available data from common house heat metering devices. For this purpose, the authors introduce the coefficient of efficient use of heat in heating systems kp.i.. The proposed coefficient is the ratio of the used heat drop to the temperature in the supply pipeline of the heating system. The paper shows an example of determining the coefficient of efficient use of heat energy before and after major repairs of the in-house heating system of an apartment building. Analysis of heat metering data allows us to identify buildings with the lowest values of the proposed coefficient. Such buildings become the main candidates for detailed instrumental inspection of in-house heating systems, and if there are signs of physical wear, for their major repairs. The proposed algorithm of actions, when implemented, allows achieving the greatest effect on energy saving and improving the quality of heat supply in cities with the allocated funding.
