地源热泵系统地中集热器的施工工艺

The technology of underground energy collector in GSHP systems

在地源热泵系统中,地中集热器的施工质量对于系统运行的作用是至关重要的。地中集热器的材料 要求耐腐性好、承压能力强、接口密封性好、无泄漏点;能源井的制作要求垂直度好,能在较长时间内不坍塌; 填料的回灌要保证密实,减少集热器与周围土壤的接触热阻。文章对地中集热器的施工做了分析,提出了保证 系统完备性的施工方案。

Ground source heat pump brings heat to indoor from underground for supplying heat in winter, and it give out heat to underground from indoor to attain cool in summer, so it is very important to insure the project quality of underground energy collectors. Energy collectors should be durable and sealed up. The wells should be upright and not collapse in a period of time. The backfill should fill the wells well, not leave any space. The author brings up the self-contained way from the years-programming experiences.
