| 摘 要： | 建立了应用于地源热泵系统的水平埋管的传热数学模型,并采用 ANSYS 软件模拟了埋深为 3 m 的水平埋管在冬夏运行工况下周围土壤的温度场变化。根据选取的特定时间比较了单管和双管水平埋管在相同工况下周围土壤温度场,得出各自的影响半径,为水平埋管换热器的埋设提供了参考。

| Abstract: | The mathematics model for heat transfer is set up and the soil temperature change around the horizontal under ground heat exchangerinwinterand summer are simulated bythe software Ansys. The soil temperature field around the single pipe with which between the two double pipes in the same condition are compared and the effective thermal radius are gained respectively. That offers the reference for designing the horizontal ground heat exchanger. |
