| 摘 要： | 在单根U型垂直埋管周围土壤传热模型的基础上建立管群的传热模型。通过MATLAB软件中的PDE工具箱求解U型垂直埋管管群周围非稳态温度场。通过对夏季制冷工况的模拟，确定一定条件下管群间的热干扰及其发生时间，定量预测热干扰的程度及其结果。通过对管群间热干扰的分析，提出解决方案，为U型垂直换热埋管的地下管群的设计提供参考依据。

| Abstract: | Establishes heat transfer pipes of ground source heat pump model of the soil temperature field around U-vertical based on the model of single U-vertical pipe. Solves the transient temperature field around U-vertical multi-pipes by using PDE tools in the MATLAB software. By making the simulation of cooling mode in summer, obtains the thermal disturbance in some conditions, the time when the disturbance happens, the extent and result in the vertical multi-pipes. According to the analysis of the thermal disturbance, brings forward a resolved method, which can offer reference in the design of the buried U-vertical multi-pipes. |
