An experimental investigation of the accuracy of thermal response tests used to measure ground thermal properties

Abstract
This paper reports on the results of thermal response tests conducted with laboratory-grade instrumentation and equipment
for a borehole system consisting of nine groundwater-filled boreholes, each about 80 m (262 ft) deep. The ground thermal
properties, including the undisturbed ground temperature, the thermal conductivity and the borehole thermal resistance, are
determined for each of the nine boreholes using standard evaluation methods. Comparison of the results of the ground
thermal properties of the nine boreholes provides meaningful insight into the uncertainty issue of the thermal response tests.
The ground thermal conductivity and the borehole thermal resistance estimations of nine boreholes are then used... (More)
This paper reports on the results of thermal response tests conducted with laboratory-grade instrumentation and equipment
for a borehole system consisting of nine groundwater-filled boreholes, each about 80 m (262 ft) deep. The ground thermal
properties, including the undisturbed ground temperature, the thermal conductivity and the borehole thermal resistance, are
determined for each of the nine boreholes using standard evaluation methods. Comparison of the results of the ground
thermal properties of the nine boreholes provides meaningful insight into the uncertainty issue of the thermal response tests.
The ground thermal conductivity and the borehole thermal resistance estimations of nine boreholes are then used to
investigate the sensitivity of the design of borehole systems to the random variations in the estimated thermal properties. The
paper also presents the effects of the test duration and the heat injection rate on the estimated ground thermal properties
when conducting thermal response tests. (Less)
