  1. 1. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Haoyang Dong; [2022]
    Nyckelord :borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

    Sammanfattning : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. LÄS MER

  3. 2. Monitoring of a heat pump system using deep borehole heat exchangers

    Master-uppsats, KTH/Energiteknik

    Författare :Baptiste Delattre; [2018]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  4. 3. Construction and test of a new compact TRT equipment

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Linus Olausson; [2018]
    Nyckelord :;

    Sammanfattning : A relevant contribution to sustainable development can be achieved by providing efficient solutions for heating buildings. The use of a heat pump taking heat from the bedrock with the help of a borehole heat exchanger is a common solution in Sweden to accomplish this. LÄS MER

  5. 4. Transient modeling of a high temperature borehole thermal energy storage coupled with a combined heat and power plant

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Malin Malmberg; [2017]
    Nyckelord :;

    Sammanfattning : Coupling High-Temperature Borehole Thermal Energy Storages (HT-BTES) with existing Combined Heat and Power (CHP) systems is a promising approach to increase energy efficiency of district energy systems through recovery of otherwise wasted heat. This solution is currently being discussed in Sweden by the company Tekniska Verken in Linköping AB, for storing waste heat from their CHP operation in summer in a HT-BTES and to utilize it during peaks in winter.

  7. 5. Alternativa etanolbaserade köldbärare med korrosionsinhibitorer i bergvärmesystem

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Marcus Ohlin; [2015]
    Nyckelord :;

    Sammanfattning : Ground source heat pumps are very popular in the Nordic countries. The method of exchanging heat with the ground is based on the principle that a secondary fluid is circulating through a U-pipe borehole heat exchanger inserted into energy wells. LÄS MER
