基于探针法与热响应法的岩土热物性测试对比分析

A comparative analysis of geothermal thermal property tests based on probe method and thermal response method

通过对Hot Disk测试仪测得岩土热物性参数与现场热响应法测试结果的对比,发现在实验室里测得的导热系数与现场热响应测得的导热系数差别较大,在进行地源热泵设计与选型时,应进行现场热响应试验确定在加热或冷却功率下测得的土壤导热系数,以此作为选型依据。

After the comparison between the thermal property parameters of the Hot Disk tester and the obtained test results of the field thermal response,it is found that the thermal conductivity measured in the laboratory is significantly different from the thermal conductivity of the field.During the design and selection of the ground source heat pump,the thermal conductivity of soil measured under heating or cooling power should be determined,which can be the selection basis.
