热网可靠性、限额供热工况及优化研究进展OA

The research progress on heating network reli-ability,limited heating conditions,and optimization are reviewed.Scholars at home and abroad have conducted in-depth studies on heating network reliability.In China,the research on heating network reliability started relatively late,but on the basis of fully drawing on foreign experience,adaptive improvements and de-velopments have been made in light of the characteris-tics of domestic heating systems.Domestic scholars have studied the impacts of factors such as the outdoor design temperature for heating,the characteristics of building envelopes,the minimum allowable indoor tem-perature,and the structure of heating networks on the duration of limited heating and the heating balance un-der limited heating conditions.Domestic research on heating network optimization is mainly carried out from aspects such as structural optimization,design optimi-zation,and operation optimization.The introduction of genetic algorithms and ant colony algorithms provides technical conditions for the design optimization of com-plex heating networks.
