Abstract

En 中文
• Hourly dynamic simulation based on real operational data from both WWTP and DH network. • Single-stage and cascade WWHP configurations compared in a third-generation DH system. • Cascade heat pump covers 74.8% of seasonal demand with an effective seasonal coefficient of performance of 2.44 • Integration reduces primary energy consumption by 41% and CO2 emissions by 54%. • Sensitivity analysis confirms robustness across European electricity mixes and wastewater flow rates.
