土壤特性对地埋管换热器传热影响分析--以唐山市区为例

摘要

The author of this paper,with Tangshan City as the subject,introduces the relation-ship between soil properties and the suitability of ground heat pumping system,puts forward a method for determining the thermal conductivity of the soil by measuring temperature changes in the soil layers,and simulates and analyzes the influence of different initial temperatures of soil layers and the soil thermal conductivity on the transfer effects of ground heat exchangers.%以唐山市区为例，介绍了土壤土质特性与建设土壤源热泵系统适宜性的关系，通过试验测定了土壤层温度的变化，给出了土壤导热系数的确定方法，并模拟分析了土壤层不同的初始温度和土壤导热系数对地埋管换热器传热的影响。
