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 کاملSensitivity analysis on the performance of a ground source heat pump equipped with a double U-pipe borehole heat exchanger
Ground Source Heat Pumps (GSHP) are economically and environmentally advantageous for the heating and cooling of buildings, provided that the long-term sustainability of the thermal exploitation of the soil is ensured. In particular, the performance of a closed-loop Borehole Heat Exchanger (BHE) strongly depends on the geometrical and physical properties of its components and on the thermo-hydr...
متن کاملHeat transfer analysis of underground U-type heat exchanger of ground source heat pump system
BACKGROUND Ground source heat pumps is a building energy conservation technique. The underground buried pipe heat exchanging system of a ground source heat pump (GSHP) is the basis for the normal operation of an entire heat pump system. METHODS Computational-fluid-dynamics (CFD) numerical simulation software, ANSYS-FLUENT17.0 have been performed the calculations under the working conditions o...
متن کاملHeat exchanger technology and applications: ground source heat pump system for buildings heating and cooling
The earth’s surface acts as a huge solar collector, absorbing radiation from the sun. In the UK, the ground maintains a constant temperature of 11-13oC several metres below the surface all the year around.1 Among many other alternative energy resources and new potential technologies, the ground source heat pumps (GSHPs) are receiving increasing interest because of their potential to reduce prim...
