Abstract:
This paper uses the constant heat flux method for thermal response test of single U and double U type buried pipe respectively which is based on ground source heat pump engineering project in Suzhou.Through this experiment,the geological condition of the project and the thermal physical parameters of rock and soil are obtained. At the same time,the performance of the ground heat exchanger under various operating conditions are calculated and analyzed.It is concluded that the average thermal conductivity of the soil in this area is 2.02 W/(m·K),and that the heat exchanger performance of double U pipes is about 15% higher than that of single U pipes.
