Abstract

The main objective of this research was to develop an apparatus which provided a controlled simulation of vertical GSHP installation conditions, and to use this apparatus to test the thermal performance of selected bentonite-additive mixtures. Operating conditions for these tests were chosen to simulate heat rejection to the soil as would be experienced under summer cooling loads. Four specific sub-objectives were selected as the logical sequence of steps toward the completion of the main objective. They are as follows. 1. Design and construct an apparatus that provided for controlled simulations of actual heat exchanger installation conditions. Provide a means for measuring the temperature and water distributions within the test sample. 2. Determine bentonite-additive mixtures to be tested, and the conditions that they should be tested under. 3. Use the apparatus to test the thermal performance of the grout-additive mixtures under the chosen operating conditions. 4. Compare the thermal performance of the grout mixtures tested based on water content, temperature, and visual inspection data.
