摘　　要：在冬冷夏热且夏季冷负荷远大于热负荷地区常采用复合式地源热泵系统,其中控制策略存在极大优化空间。当需要获得地下土壤温度分布,或将地下某点参数作为系统运行模式的控制参数时,就需要建立精确可靠的三维非稳态模型。利用FLUENT软件建立带有冷却塔的三维非稳态复合式地源热泵系统数值模型,详细介绍热泵机组,土壤换热器,冷却塔,板式换热器等主要部件的建模过程,对系统设计及运行控制策略研究提供极大帮助。Hybrid ground source heat pump system （HGSHPS） is demanded in areas where cooling loads in hot summer are much larger than heating loads in cold winter. Huge space exists in the optimization of the control method. This paper has built a dynamic numerical systematic model of HGSHPS with the CFD sottware FLUENT to research the control methods, especially when the temperatures underground is necessary. It introduces the modeling of main components including the heat pump unit, ground heat exchanger, cooling tower and plate heat exchanger in details. It helps for the research of the system design and control strategy largely.
