摘　　要：土壤源热泵系统近年来发展迅速。我国南北横跨多个气候区,每个气候区的特点各自不同。对每个气候区的土壤源热泵系统设计方案有必要进行总结。在中原地区(寒冷地区的南侧及夏热冬冷地区的北侧),分别对6个关键方案(包括土壤热平衡的措施、竖直地埋管换热器的深度和间距、土壤源系统运行策略的问题、竖直地埋管换热器单双U、竖直地埋管换热器管道的管径、冬季的供回水温差等)进行计算、分析,并举例说明,提出了设计的结论或设计原则,以期达到指导设计和借鉴的作用。The ground source heat pump system has been developed rapidly in recent years. The characteristics of different climatic zones are various from north to south in Chinca Therefore, it is necessary to summarize the design of the ground source heat pump system for each climatic region. Six key design projects, including the soil heat balance, the depth and width of vertical buried tube heat changer, the operation strategy of the ground source heat pump system, single and double U of vertical buried tube heat changer, the pipe diameter of ver- tical buried tube heat changer, and the temperature differential of supply and return water in winter and so on, are calculated and analyzed for the Central Plains region （the south of cold region and the north of hot summer and cold winter）. Conclusions or principles of the design are proposed and illustrated so as to guide design and be used for reference.
