摘要
结合华北某地源热泵热响应试验,对岩土热响应试验中的关键问题进行了分析,对岩土热响应试验的方法和步骤进行了详细说明。对该项目场区内2个120 m深双U型垂直地埋管进行岩土热响应试验,并获得土壤的综合热物性参数,得到了岩土的初始稳定以及地埋管系统的供回水温度响应曲线,进而确定了地埋管每延米的换热量等参数。
Combining with a geo-thermal response test project in North China,the key issues of geo-thermal response test are analyzed and the test methods and steps are illustrated in detail.Vertical double U-tube test wells are taken,and the comprehensive thermal parameters of ground-source are received through field test of two test wells with depth of 120 m.Furthermore,the original ground temperature and the inlet and outlet water temperature response curve of the underground heat exchanger are also obtained,which are used to determ ine the heat exchange quantity of per well depth and other parameters.
