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。 Taking Tangshan urban area as an example, the relationship between soil characteristics and soil suitability of ground-source heat pump system was introduced. The temperature of soil layer was measured through experiments. The method of determining the thermal conductivity of soil was given. Influence of Initial Temperature and Soil Thermal Conductivity on Heat Transfer in Ground Tube Heat Exchanger.
