          摘要:

          以重庆某地源热泵工程为例,通过能耗监测系统和地温监测系统的实测数据,分析了地源热泵系统2 a内的运行特性。通过分析机组进出口水温、能耗量、COP、水系统输能比以及土壤温度变化规律,发现该工程存在土壤热堆积、系统运行效率降低等问题。

          Abstract:

          Taking a groundsource heat pump project in Chongqing as an example, explores its operating characteristics with measured data from energy consumption monitoring system and ground temperature monitoring system. Analyses the parameters variation, including the inlet and outlet water temperature of the unit, energy consumption, COP of the heat pump unit and system, energy efficiency ratio of cooling water system and the soil temperature, and finds the problems of soil heat accumulation and low system efficiency.
