混合式地源热泵（HGSHP）系统利用较便宜的散热器（如干式冷却器）或热源（如太阳能集热器）来减小较昂贵GHE的尺寸。因此，它有可能比传统的地源热泵系统更具成本竞争力。HGSHP系统与热能存储（TES）系统集成后，即使地源热泵不运行，也可以充分利用成本较低的散热器或热源的可用加热和冷却输出。HGSHP与季节性TES的结合也是克服建筑物年冷负荷和热负荷之间不平衡的有效解决方案。 本文介绍了利用Modelica程序开发的HGSHP和TES集成系统的模型。使用该模型进行了一项基于模拟的初步研究，以调查伊利诺伊州芝加哥一栋供暖主导型住宅楼的HGSHP和TES集成系统的有效性。模拟结果表明，HGSHP和TES的组合可以显著提高地源热泵供暖运行时的进水温度，从而提高地源热泵的运行效率，或者可以减小GHE的尺寸，以达到与传统地源热泵系统相同的能效。 引用:2020年虚拟会议论文

A hybrid ground source heat pump (HGSHP) system utilizes less-expensive heat sink (e.g., a dry cooler) or heat source (e.g., a solar thermal collector) to reduce the size of the more expensive GHEs. It thus has the potential to be more cost competitive than a conventional ground source heat pump system. Integrated with a thermal energy storage (TES) system, a HGSHP system could make full use of the available heating and cooling output from the less- expensive heat sink or heat source even when the GSHP is not running. The combination of HGSHP with a seasonal TES is also an effective solution to overcome the imbalance between the annual cooling and heating loads of a building. This paper presents a model of the integrated HGSHP and TES system, which is developed with the Modelica program. A preliminary simulation-based study was performed using the model to investigate on the effectiveness of the integrated HGSHP and TES system for a heating dominant residential building in Chicago, IL. Simulation results indicate that the integrated HGSHP and TES can significantly increase the entering water temperature of the ground source heat pump during heating operation and thus improve it operating efficiency, or it can reduce the size of the GHE for achieving the same energy efficiency as the conventional ground source heat pump system.
