  1. 11. First step towards development of Distributed thermal response test using heating cables

    University essay from KTH/Industriell ekologi

    Author : Seyed Mazyar Hosseini Moghaddam; Joakim Holmberg Bårman; [2015]
    Keywords : ;

    Abstract : A Distributed Thermal Response Test is a method to determine ground properties such as thermal conductivity. Knowing the thermal properties of the ground is essential for designing and installing ground source heat pump and BTES systems. READ MORE

  3. 12. Feasibility study for upgrading the current heat distribution network of an existing building complex to a Smart Thermal Grid

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : John Clauss; [2015]
    Keywords : Smart Thermal Grid; Heat Pump Technology; Solar Energy; Borehole Thermal Energy Storage;

    Abstract : A feasibility study on upgrading an existing heat distribution network to a low-temperature distribution grid has been carried out during this project. The integration of a solar thermal system combined with a borehole thermal energy storage (BTES) for covering the space heating demand of the buildings as well as the application of CO2 heat pumps and water storage tanks for domestic hot water (DHW) production were investigated in order to apply more renewable energy sources.

  4. 13. 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

  5. 14. Analysis of Geo-Energy System with Focus on Borehole Thermal Energy Storage

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Holmberg Henrik; [2009]
    Keywords : ground source heat pump GSHP borehole thermal storage BTES; Technology and Engineering;

    Abstract : Ground source heat pump (GSHP) systems have become more popular lately both for residential space heating and for commercial applications. GSHP systems can use water, ground or the bedrock as a thermal source. The energy extracted is regarded as a renewable energy-source and it consists of both stored solar energy and a share of geothermal energy. READ MORE
