Hydraulic balance effect of heating systems considering exergetic sustainability

The energy and environmental sustainability of buildings is a crucial process that requires consideration alongside demand responsibility and hydraulic balance management. This study primarily involves a comparative analysis of a hydraulically balanced thermal system on campus using the entropy approach. Firstly, the effectiveness of the existing steam mechanical system and the performance of a 90/70 °C demand-side system were investigated. The environmental impact assessment of the system was assessed using the recommended environmental performance index and sustainability index criteria. The analysis showed up to 50% efficiency when choosing a balanced and demand-driven 90/70 °C system. However, the potential efficiency reached 77%, according to the environmental impact analysis. The sustainability analysis alone showed a gain of 39.65%. This text provides suggestions on the importance and sustainability of hydraulic balance in enhancing the efficiency of a working system.
