安徽地源热泵应用区域的地温变化预测

Prediction of Soil Temperature in Areas of Ground Source Heat Pump in Anhui Province

通过建立浅层地温预测模型,对安徽地源热泵系统开发利用浅层地热能进行了区域性浅层地温变化模拟预测;分别预测评价了在不同的岩土体、不同的冷热负荷不平衡率、不同的地埋管深度、不同的管间距及不同管群布置方式等条件下,地源热泵系统运行时的浅层地温变化情况;提出了开发利用条件下的地温热平衡措施。

The paper presents the predication of variation of underground soil temperature in the area of ground, source heat pump （GSHP） sy＆tem located in Anhui, The underground soil temperature of GSHP system operating for 20 years with different cooling and heating load ratio, different tube spacing, different under-ground soil parameters and dijferent nest of tubes arrangement are simulated. Different ways to balance the underground sail temperature on the basis of the simulation results are proposed.
