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...
متن کاملA New, Small, Wireless Instrument to Determine Ground Thermal Conductivity In-Situ for Borehole Heat Exchanger Design
A small, light, wireless borehole probe has been developed and built which consists of pressure and temperature sensors and a mini-datalogger/programmed microprocessor in a closed metal tube, water-tight up to 100 bar. The probe (235mm long, 23mm dia, 99.8 g) sinks in completed but not yet working borehole heat exchangers (BHEs) through its own weight to the bottom of the BHE U-tube and records...
متن کاملAnalysis of ground heat exchanger for a ground source heat pump: A study of an existing system to find optimal borehole length to enhance the coefficient of performance
Ground Source Heat Hump is one of the emerging technic to utilize the reservoir of geothermal energy in Europe. The crucial factor is to find the optimal length of the borehole to successfully design a heating system. The length of the borehole varies depending on the geographical area, the capacity of the heat pump and heat load of the desired building in consideration. Several methods have be...
متن کاملModel-Based Performance Analysis of a Single Borehole in Ground Heat Exchanger
Ground Source Heat Pumps (GSHP) are high efficient HVAC equipment that provide heating and cooling for buildings. The high initial cost of drilling boreholes is one of the main reasons that hinder the widespread application of GSHP. It is very important to develop proper design methods to predict and evaluate the performance of the Ground Heat Exchanger (GHE) throughout its entire life span. In...
متن کامل3D 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...
