Quality Control of Borehole Heat Exchanger Systems

The vast growing market for borehole heat exchangers (BHE’s) requires great efforts of quality assurance in design and construction. Within a research project funded by the German Federal Ministry of Economics and Technology a consortium consisting of the University of Applied Sciences at Biberach (UASB), the University of Karlsruhe (EIFER, GI) and the Bavarian Centre of Applied Energy Research...

3D Simulation of the Thermal Response Test in a U-tube Borehole Heat Exchanger

Simulated Thermal Response Test data are analyzed in order to evaluate the effect of the tridimensionality model’s feature in determining the proper value of the soil thermal conductivity and borehole thermal resistance, necessary for the geothermal energy storage systems’ design in real conditions. The 3D system’s simulation during the Thermal Response Test is realized by adopting the finite e...

An extended two-dimensional borehole heat exchanger model for simulation of short and medium timescale thermal response

Common approaches to the simulation of Borehole Heat Exchangers (BHEs) assume heat transfer in circulating fluid and grout to be in a quasi-steady state and ignore fluctuations in fluid temperature due to transport of the fluid around the U-tube loop. Such effects have been shown to have an impact on peak temperatures and hence operation of heat pumps systems when short time scales are consider...
