Multi-index Comprehensive Evaluation for the River Source Heat Pump Energy Supply System Based on Dynamic Weighting

The river water source heat pump energy supply system has technical difficulties in selecting evaluation indicators, determining weights, and establishing comprehensive evaluation models due to its environmental benefits and diverse design options. In response to these problems, the article analyzes the working principle and operating characteristics of the river water source heat pump energy supply system, and builds an index system that includes the economic, energy consumption and environmental protection factors of the river water source heat pump. In order to obtain better index weights, the article proposes the AHP-ENTROPY weighting method based on the scientific and reasonable combination of subjective and objective weighting methods. In addition, considering the dynamic changes of the index weights in different system scenarios, the weights are dynamically modified in combination with specific operating scenarios to achieve dynamic weighting of the related indicators. The analysis result of the calculation example shows that the evaluation method proposed in the article realizes the comprehensive evaluation of the river water source heat pump energy supply system and the evaluation results are intuitive and consistent with reality.
