            摘要:

            以某醫院大型地源熱泵系統為研究對象,介紹了方案分析及能源系統設計,包括:負荷預測、地埋管設計、容量配置優化、工藝流程、自控系統等內容。對系統的夏季和冬季運行工況進行了實測,并對測試結果進行了分析。采用模擬軟件對系統的運行情況進行了動態仿真,并與實測數據進行對比,以驗證運行效果。結果表明,該地源熱泵系統能效高,達到了設計預期效果。指出了該系統運行過程中存在的一些問題。

            關鍵詞:醫院,地源熱泵系統,動態模擬,測試,能效比

            Abstract:

            Taking a large-scale ground-source heat pump system of a hospital as the research object, presents the scheme analysis and energy system design, including load forecasting, design of ground heat exchanger, capacity configuration optimization, technical process and automatic control system. Tests the operation data in summer and winter conditions, and analyses the measured results. Performs the dynamic simulation of system operation by software, and compares the simulation results with test results to verify the operation effect. The results show that the ground-source heat pump system has high energy efficiency and achieves the expected design effect. Presents some problems of system operation.

            Keywords:hospital,ground-sourceheatpumpsystem,dynamicsimulation,test,energyefficiencyratio
