| 摘 要： | 对不同管间距的垂直U型地埋管进行了夏季工况连续实验,比对单U地埋管换热器不同管间距下的单位井深换热量、管群内土壤温度变化和系统运行情况,结果表明,管间距越大,单U换热器和土壤之间换热效果越好,管群内的热干扰越弱;管间距过小,系统内换热器的换热情况将恶化,导致不能长期稳定运行。

| Abstract: | Experiments were conducted on different distance of U-vertical ground heat exchanger. Compared to the heat exchange unit depth, the soil temperature change and system operation showed that the farther of tube distance, the better heat exchange between the ground heat exchanger and soil , the weaker thermal interference of tube ground; the smaller of tube distance, the system can not in stale condition due to the bad heat transfer of tube exchanger. |

| Keywords: | ground source heat pump operating performance different tube distance experimental study |
