摘要
平均热物性参数的大小对钻孔的数量及钻孔的深度具有显著的影响 ,进而影响地源热泵系统的初投资。为了能够在现场测量地下岩土的平均热物性参数 ,利用一套现场测量设备测量了对地下埋管回路施加的热流与回路中循环水温度随时间的变化 ,使用自行开发的软件 ,采用参数估计方法 。
The magnitude of average thermo-physical parameters exerts a significant influence on the number and depth of holes to be drilled, thus affecting the capital investment outlays for a ground-source heat-pump system. To realize the on-site measurement of the average thermo-physical parameters of underground rock soil, a set of on-site measuring equipment was put into use. With its help measurements were taken of the heat flow an underground embedded pipe loop is subjected to and of the temperature change of the circulating water in the loop with the passage of time. Moreover, a piece of software developed by the authors was utilized to calculate and determine the average thermo-physical parameters of the underground rock soil by using a parameter-evaluation method.
