For the purpose of using soil as a heat source, we conducted a long-term heat collection experiment emploving a steel pipe pile as a heat exchanger with soil. From the experimental data, we confirmed that the quantity of heat collected from the soil per day was to be about 23kWh and the high performance of coefficient (COP=3.3) for the GSHP, in a stationary state. Numerical calculation results agreed well with the long-term experimental results, which showed that the calculation method could estimate the heat collected rate from the soil during a long-term operation of the heat collection system.
