本报告的作者首先收集了GCHP资本成本信息，然后设计并测试了实验系统，以收集GCHP泵送/管道组件和系统的其他运行特性。这导致开发了一种确定地源热泵系统需求和能量的方法，以及一种估算地源热泵泵/管道组件和系统成本的工具。报告中包括了结果。该报告还包括GCHP泵需求/能量法和GCHP管道成本估算工具的示例和程序。

The authors of this report first gathered GCHP capital cost information, then designed and tested experimental systems to collect additional operating characteristics of GCHP pumping/piping components and systems. This led to the development of a method for determining the demand and energy of GSHP pump systms and a tool for estimating the cost of GCHP pumping/piping components and systems. The results are included in the report. The report also includes examples and procedures of the GCHP pump demand/energy method and GCHP piping cost estimating tool.
