摘　　要：以华东地区的某大型客站复合式地源热泵系统为研究对象,通过对系统的连续实地测试,在其供冷季节的实测数据基础上,分析系统运行策略对地源热泵地埋管换热性能和机组性能的影响,提出其运行策略的优化途径,并以系统仿真软件TRNSYS为平台,搭建系统仿真模型,通过模拟系统多年运行,分析三种运行策略的可行性,认为夜间间歇的地源热泵机组优先制冷的运行方式,有利于系统的多年稳定运行,是较优的运行策略。Based on the measured data in the cooling season, this research analyzes the impact of the operation strategy of HGSHP （ Hybrid Ground Source Heat Pump） system on the performance of heat pump unit and ground heat exchanger. The objective building is a large railway station in East China. Different operation strategies to optimize the performance are proposed, and the heat transfer charaeteristics of ground heat exchanger in 10 years under three operation strategies are compared through the system simulation on TRNSYS. It＇ s concluded that the operation strategy that GSHP is at high priority with nocturnal intermittent for cooling is beneficial to a stable operation of HGSHP system.
