  1. 1. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    University essay from KTH/Energiteknik

    Author : Max Hesselbrandt; [2021]
    Keywords : ;

    Abstract : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

  2. 2. Performance evaluation of ground source heat pump heating systems in Stockholm

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : MARCUS BÖRJESSON; [2020]
    Keywords : Ground source heat pump system; GSHP system; vertical borehole; ground heat exchanger; BHE; EED; evaluation; COP; SPF; Ideal temperature dependent SPF; temperature dependent SPF efficiency; SEPEMO; Sweden; Bergvärmesystem; borrhål; kollektor; EED; utvärdering; COP; SPF; ideal temperaturberoende SPF; temperaturberoende SPF-verkningsgrad; SEPEMO; Sverige;

    Abstract : GSHP systems are common in Sweden but there are few evaluations quantifying the performance of the systems and highlighting problem that occurs during operations. The research project Annex 52 Long-term performance measurement of GSHP systems serving commercial, institutional and multifamily building part of IEA HPT TCP proves the need to systematically be able to evaluate GSHP systems.

  3. 3. Sensitivity Analysis and Optimization of the Vertical GSHP (Ground source heat pump)

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Sriram Ramanathan; [2020]
    Keywords : GSHP; Borehole heat exchanger; Geo-thermal energy.;

    Abstract :   GSHP (Ground source heat pump), uses geothermal energy which is a form of green and sustainable energy.  Geothermal energy is also a continuous source of energy, unlike wind energy. The results from this thesis work will be applicable for both GSHP that are being used for space heating, and the ones which have a bottom organic Rankine cycle. READ MORE

  4. 4. Modelling the performance of heat pump systems for single-family house applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mar Coronado Pons; [2019]
    Keywords : ;

    Abstract : Ground source heat pumps (GSHP) extracting the heat through borehole heat exchangers (BHEs) are an extremely efficient way to provide heating. Their performance is affected by the temperature of the thermal source: the ground; the higher it is the temperature of the ground, the higher their performance. READ MORE

  5. 5. Monitoring of a heat pump system using deep borehole heat exchangers

    University essay from KTH/Energiteknik

    Author : Baptiste Delattre; [2018]
    Keywords : ;

    Abstract : Sweden has been one of the first countries in the world to use ground-source heat pumps (GSHP) to supply heating and cooling to its buildings. Today, it is the leading country in Europe and new installations tend to have larger capacities. READ MORE
