Abstract

In this paper, new approaches for testing and interpreting ground thermal conductivities in Ground-Coupled Heat Pump (GCHP) systems were proposed. With the application of Horner plot method, developed in petroleum engineering, the new approach does not require the condition of constant heat flux during the thermal response test. The application of the new interpretation method to field test data showed reasonable agreement with conventional methods, while proposing the requirement of multi-point down-hole temperature measurements when testing heterogeneous formations. The evaluation of skin factors using the new approach showed that the temperature loss around boreholes due to the small thermal conductivity of grouting material would be of less importance than conventionally evaluated.
