地面耦合热泵（GCHPs）在商业建筑领域的使用不断增加。由于这一增长，更多关心这些系统的正确设计、安装和操作的工程师发现自己正在处理与充分地下水保护有关的问题。垂直钻孔换热器（BHEx）可以穿透两个或多个必须保持分离的水源。不鼓励地表水和浅层含水层之间或两个或两个以上含水层之间的水交换，管理法规通常不允许这种交换。本研究旨在进一步了解地下水运动、GCHP行业采用的替代钻孔完井方法，以及任何确定的完井方法对BHEx设计的影响。

The use of ground-coupled heat pumps (GCHPs) in the commercial building sector is continually increasing. Because of this increase, more engineers who are concerned with the proper design, installation, and operation of these systems find themselves dealing with issues related to adequate groundwater protection. The vertical borehole heat exchanger (BHEx) can penetrate two or more water sources that must remain separate. Water exchange between surface water and shallow aquifers or between two or more aquifers is discouraged and generally not allowed by governing regulations. This study was undertaken in an effort to learn more about groundwater movement, the incorporation of alternative borehole completion methods by the GCHP industry, and the impact of any identified completion methods on BHEx design.
