众所周知，与传统暖通空调系统相比，地源热泵（GSHP）系统具有显著的节能潜力，并表现出优越的性能。为了保证地源热泵系统的可靠性和高效性，研究人员和工程师们在地源热泵系统的研究和改进方面做出了大量的努力。然而，与其他传统暖通空调系统（例如使用冷却器和冷却塔的系统）不同，地源热泵系统的长期监测和分析非常重要，尤其是考虑到在各种建筑热/冷负荷下，地面温度年复一年的可能变化。地面温度的变化可能会严重影响地源热泵系统的系统效率，有时甚至可能导致系统无法为建筑物提供足够的加热/冷却效果。 因此，本文对美国寒冷气候区的垂直闭环地源热泵系统进行了长期监测和模拟。建立了TRNSYS模拟模型，首先利用测量数据对模型进行了校准，然后利用该模型预测未来地温的变化。此外，还通过灵敏度分析确定了地源热泵系统的关键设计参数。结果表明，与研究的其他设计参数相比，该建筑的土壤导热系数对地面温度有显著影响，改变钻孔间距比增加钻孔数量对冬季地面温度的影响更大。对于南墙上安装了大量窗户并配备了地源热泵系统进行空间供暖和制冷的办公楼，使用不同的分区策略可能会极大地影响能源模拟结果。 引用:2019年年度会议，密苏里州堪萨斯城，会议论文

It is well known that Ground Source Heat Pump (GSHP) systems have the potential for significant energy savings and have demonstrated superior performance compared to conventional HVAC systems. Researchers and engineers have made lots of efforts in the study and improvement of GSHP systems in order to ensure the reliability and high efficiency of this type of system. Nevertheless, unlike other conventional HVAC systems, e.g., a system using chillers and cooling towers, the long-term monitoring and analysis of a GSHP system are significantly essential, especially considering the possible variation of the ground temperatures year after year under various building heating/cooling loads. The change of ground temperatures may substantially affect the system efficiency of a GSHP system and sometimes may even cause a failure of the system in providing enough heating/cooling effect to buildings. Therefore, this paper focuses on the long-term monitoring and simulation of a vertical closed-loop GSHP system used in the cold climate region of the U.S. A TRNSYS simulation model was established, which was calibrated first by using the measurement data and then utilized to forecast the future variation of the ground temperatures. Additionally, the critical design parameters of the GSHP system are identified by conducting a sensitivity analysis. The results show that for this building, the soil thermal conductivity has a significant impact on the ground temperatures compared to other design parameters studied, and changing the borehole separation distance has a greater impact on the ground temperatures during winter than increasing the number of boreholes. The use of different zoning strategies may greatly affect the energy simulation result for an office building with a large number of windows installed on the south walls and equipped with a GSHP system for space heating and cooling.
