Hot Properties of Soil Testing and Analysis for Ground Source Heat Pump

When designing of ground heat exchanger pipe system, the thermal properties of soil parameters is very important, it is significant effects for size of the drilling depth, so the accuracy of the measurement system strongly affects the performance and economy. In this paper, comparing with other test method, the commonly method used in the current testing was the best way to determine the thermal properties of the soil. The system temperature changes are mainly concentrated for the side of the pipe in the ground, accounting for 68% of the total system temperature changing, when we design ground heat exchanger pipe system, it is proposed that it is designed to strengthen water and soil heat transfer, or use the inlet heat transfer effect for good characteristics.
