本文介绍了北京市某大学地源热泵空调系统中地埋管换热器部分施工的全过程,重点讨论山区室外打井及回填工艺中所遇到的技术难点和解决办法。各项数字表明,岩石层地源井与砂粘土层地源井比较起来,其导热系数要高出3倍左右。该项目的成功实施填补在山区推行地源热泵技术的空白。

The construction of a ground source heat pump air-conditioning system in a University of Beijing was introduced in detail,focused on the technical difficulties and solutions of the mountain and filling processes of outdoor wells.The figures show that the rock layers in the source well and sandy clay layer of ground source wells in comparison,its thermal conductivity to be higher than 3 times.The successful implementation of the project filled the gaps in the field of the ground source heat pump technology in mountain area.
