研究了热回收地源热泵（HR-GSHP）系统的设计和运行方法。本文首先介绍了一种应用优化方法对HR-GSHP系统进行设计的方法。通过应用该设计方法，HR-GSHP系统中每个地源热泵（GSHP）机组的总热负荷和冷负荷最大化，以响应任意设置的地源热泵（GHEX）总长度。这意味着，按照设计方法设计的HR-GSHP系统可以在给定的GHEX总长度下产生最大的节能效果。接下来，假设总GHEX钻孔长度为7200米的HR-GSHP系统安装在一座大型综合建筑中，该建筑全年同时需要供暖和制冷，并使用设计方法确定每个地源热泵机组的每小时热负荷和冷负荷。 结果证实，HR-地源热泵系统的热负荷约为传统地源热泵系统的4.3倍。此外，使用地源热泵系统的设计和性能预测工具，对HR-GSHP系统的年度运行进行了模拟。模拟中给出了按设计方法确定的小时热负荷。HR-GSHP系统的平均性能系数（COP）在加热时为4.6，在冷却时为10.3。因此，与传统地源热泵系统相比，HR-GSHP系统不仅在可覆盖的热负荷量方面，而且在COP方面都具有优势。引用:2017年年度会议，加利福尼亚州长滩，会议论文

A method for the design and operation of a heat-recovery ground-source heat pump (HR-GSHP) system has been investigated. In this paper, a designmethod for the HR-GSHP system by applying the optimization method was first introduced. By applying the design method, the total heating and coolingloads of each ground-source heat pump (GSHP) unit in the HR-GSHP system were maximized in response to an arbitrarily set total length of theground heat exchanger (GHEX). This means that the HR-GSHP system designed with the design method could yield the maximum energy saving effectfor a given GHEX total length. Next, it was assumed that the HR-GSHP system with a 7,200-m total GHEX borehole length was installed in alarge scale complex building, which required both heating and cooling at the same time throughout the year, and the hourly heating and cooling loads ofeach GSHP unit was determined using the design method. As a result, it was confirmed that the HR-GSHP could cover approximately 4.3 times theheat load of a conventional GSHP system. In addition, the simulation of annual HR-GSHP system operation was performed using the design andperformance prediction tool for the GSHP system. The hourly heat load determined by the design method was given in the simulation. The averagecoefficients of performance (COP) for the HR-GSHP system were 4.6 for heating and 10.3 for cooling. Thus, the HR-GSHP system was advantageousin not only the amount of heat load that could be covered but also the COP compared to the conventional GSHP system.
