  • Analytical Modelling of Short-term Response of Ground Heat Exchangers in Ground Source Heat Pump Systems

    • Short-term variations in the response of ground heat exchangers (GHEs) have significant effects on the overall performance of ground source heat pump (GSHP) systems. In this paper, a review of existing analytical solutions to determine the short-term response of the GHE is presented. The strengths and limitations of the noteworthy analytical solutions are high¬lighted and the transient heat transfer as considered by these solutions is critically analy¬zed. The short-term response predicted by the existing analytical solutions is pre¬sented and com¬pared to the response predicted by a new comprehensive analytical solution.

  • Modelling for optimizing brine temperature in ground source heat pump systems
  • 2009
  • Ingår i: 8th conference on sustainable energy technologies, Aachen, Germany, 2009-08-312--09-03. Proceedings vol. CD-proceedings. - 978-3-9813246-1-7

    • The potential for high energy efficiency of ground source heat pump systems has resulted in rapidly growing numbers and sizes of such installations. The energy efficiency potential of a ground source heat pump system can be further enhanced by optimized design of the ground collector and storage system. A key parameter is the brine temperature and this paper evaluates some methods for its calculation. We also introduce three key numbers to characterize ground storage systems and their load situation. Finally, the effects of different building load patterns and borehole system designs and configurations on brine temperature are analyzed.
