摘要
The performance of the ground heat exchanger was determined using the effective soil thermal conductivity and thermal resistance, both of which can be measured using the thermal response test (TRT). Hence, we demonstrated a method for estimating the performance of ground heat exchangers using TRT results. Furthermore, we estimated the performance of the Geo-Mex R3 eight-tube ground heat exchanger. The thermal resistance of the Geo-Mex R3 borehole was calculated as 0.0738 (m K)/W. The data predicted from the thermal resistance of the borehole suggested that the heat transfer rate of the Geo-Mex R3 was greater than that of the single and double U-tube types by a factor of approximately 2 and 1.2, respectively. © 2021 by Begell House, Inc.
