武汉某地源热泵项目后评估分析

Post- Evaluation of a Ground Source Heat Pump System in Wuhan

为了解武汉市某住宅小区地源热泵系统的应用效果,基于该系统的设计参数和能效测评结果,对比研究分析了系统的运行状况。结果显示,该系统的整体运行效果较好,可以满足应用需求,测试期间系统的COP值高于其设计值,水泵的能耗比例合理,取得了较好的经济效益和社会效益。但同时也发现了冷冻水系统的输能比略高于规范中的限值等问题。

To understand the application of ground source heat pump system（GSHPs） in a residential community of Wuhan City, this paper compares and analyzes the operation of the system based on its design data and the result of energy efficiency evaluation. The result shows that the system operates well and meets the application requirements. During the test period, the COP of system was higher than its design value, and the proportion of pump energy consumption is reasonable. The system achieved good economic and social benefits. However, some issues in this system needs concerns, such as the electricity consumption to transfer cooling quantity ratio of chilled water system was higher than the specification limits during the test period.
