Type of monograph: Booklet
Summary
In order to design cost-effective systems, designers of ground-source heat pump (GHP) systems with vertical ground heat exchangers need reliable data on the thermal properties of the soil/rock formation. This report presents a new method for determining thermal properties from short-term in situ tests using a parameter estimation technique. Unlike other analysis methods, this new method is not affected by short-term variations in heat input during the test. It can accurately determine properties from short-term in-situ field tests. The method has been laboratory- and field-tested. This document can be downloaded from: www.eren.doe.gov/femp/financing/ghpresources.html. A Windows-based program incorporating the geothermal properties measurement model has been developed and is being distributed free of charge via the Web site indicated below.
