贵阳某地埋管地源热泵系统项目工程分析

An Innovative Geothermal System in Guiyang

我国地源热泵技术虽然起步较晚,但是近几年地源热泵技术正以突飞猛进的态势发展。目前,该技术被广泛应用在建筑采暖、空调和热水供应等多项领域。对地源热泵系统做了简要的论述,根据场地区域地质条件,结合项目建筑物周围面积较小,布置单一的双U竖直埋管面积不够的情况,制定了双U竖直埋管换热器与桩基螺旋盘管换热器相结合的地埋管地源热泵系统方案,取得良好效果,为地埋管地源热泵技术在该地区的应用发展提供参考。

Although the late start of the geothermal pump technology in China, it has a rapid development in recent years. The geothermal pump has a wide application in hot air and water supplies and air conditioning areas. This paper briefly discusses the principles of the geothermal pump technology and then presents a case history of geothermal application. The proposed site has a relatively small footprint but a single vertical U pipe could not meet the supply requirement for the building. A new double vertical U pipe heat exchange system in combining the spiral coil heat exchange system of the foundation piles was developed for the project. The results are satisfactory.
