摘　　要：建立氨水蓄能土壤源热泵集成系统工作过程的动态数学模型,并以北方地区一典型的独立住宅为例,按照全量蓄能策略运行,对集成系统的耦合关系进行初步的数值模拟。结果表明,冬季地埋管换热器内循环液进出口的平均温度越高,夏季越低,地上机组各设备的工作性能越好。模拟结果对进一步研究集成系统间的相互耦合关系和各设备间的设计、匹配、选型等提供一定的基础数据。Establishes the working dynamic model of the integrated NH3-H2O soultion energy storage and ground source heat pump （GSHP） system. Taking a typical independent house for example, primary numerically simulates the integrated system coupling performance under the full storage stralegy. The results show that the in-out average ternperature of circulation liquid in the buried heat exchanger is higher in heating mode, or is lower in the cooling mode, the working characteristics of all the equipment above ground is better. The simulation results are very helpful for further studying the coupling performance for the integrated system, and also can provide base data for these equipments detailed design,matching and selection.
