with buried depth of 70 m is able to provide the highest heat exchange rate per unit depth (54.1 and 47.0 W/m under heat …

exchanger, the prediction method of ground heat exchange rate was developed with numerical simulation model. The developed model … studies on prediction of heat exchange rate (HER) have been conducted at different conditions of design and installation with …

circulated water were also measured to calculate the heat exchange rate. The double-tube had the highest heat exchange rate …, followed by the multi-tube and U-tube GHEs. For example, the average heat exchange rate of GHEs over 24h of continuous … increasing flow rate increased the heat exchange rate of the GHEs. The heat exchange rates increased significantly for flow rate …

grout. Present study evaluates heat exchange rate per depth of GHE by calculating the total thermal resistance, and compares … temperature and soil type, on the thermal resistance and heat exchange rate are analyzed. Experimental data from several real …
