| 摘 要： | 钻孔周围岩土热导率、单位体积定压热容与钻孔内热阻是土壤源热泵地埋管换热器设计的主要参数。采用基于线热源理论的参数估计法计算岩土热物性参数，对理论值施加高斯噪声扰动得到不确定因素影响的模拟值。通过数量级比较和参数估计法处理理论值和模拟值，分析各参数间的相互影响。岩土的单位体积定压热容对钻孔周围岩土热导率的影响较小，钻孔周围岩土热导率对其他两个参数的影响较大。

| Abstract: | Soil thermal conductivity around boreholes,soil heat capacity at constant pressure per unit volume and borehole thermal resistance are main parameters in design of buried tube heat exchanger of ground-source heat pump.The soil thermophysical properties are calculated by the parameter estimation method based on line heat source theory,and the simulation values influenced by uncertain factors are obtained by adding random Gaussian noise to the theoretical values.Through order of magnitude comparison and proce... |
