  1. 6. Analysis of borehole heat exchanger in an existing ground-source heat pump installation

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Marc Derouet; [2014]
    Keywords : ground source heat pump; borehole heat exchanger; g-function; analytical solution; temperature prediction;

    Abstract : Ground-source heat pumps systems (GSHP) are commonly used all over Sweden to supply heat and sometimes cool to different kinds of housings or commercial facilities. Many large installations are by now between 10 and 20 years old. READ MORE

  3. 7. Heat exchange phenomena and COP evaluation in heat pump systems coupled to single borehole heat exchangers

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Francesco Casellato; [2013]
    Keywords : borehole; COP; convection; geothermal; heat pump;

    Abstract : In recent years a growing interest in Borehole Heat Exchangers (BHEs) has been shown in Europe thanks to the increase of installations in systems connected to Ground Source Heat Pumps (GSHPs) used for heating and cooling needs. Different geometries and technical solutions have been de- veloped in order to improve heat exchange with the ground, accompanied by several descriptive models. READ MORE

    Abstract : In 2010, the Ground Source Heat Pumps (GSHPs) market in the European Union went up over one million (1 014 436 units at the end of 2010 according to EUROBSERV’ER 2011). In 2011, it was estimated around 1.25 million according to Bayer et al. (2012). READ MORE

  5. 9. Comparison of different Line Source Model approaches for analysis of Thermal Response Test in a U-pipe Borehole heat Exchanger.

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Patricia Monzó; [2011]
    Keywords : Borehole Thermal Energy Storage; Borehole Heat Exchanger; Ground Heat Pump System; Thermal Response Test;

    Abstract : Ground Source Heat Pumps (GHSPs) is a relevant application and around 3 million installations are setting up at the beginning of 2010 (IEA ECES Annex 21). The improvements in GSHPs are currently focused on the optimization of the system and the reduction of costs installations. READ MORE
