| 摘 要： | 介绍了地源热泵空调系统中基于线热源模型结合参数估计法下的4种岩土热物性计算方法,结合工程实例对比分析了这4种方法的计算结果。建议在实际工程中采用三参数估计法来计算岩土导热系数、钻孔内热阻和岩土容积比热容为妥。

| Abstract: | Four calculation methods to determine the ground thermal properties based on the line heat source model combined with parameter estimation in the ground source heat pump system were analyzed by a project example.The three parameter estimation method was recommended to calculate the ground thermal conductivity,the borehole inside thermal resistance(BITR),the volumetric specific heat capacity(VSHC) in practical engineering. |
