    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Linus Olausson; [2018]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Malin Malmberg; [2017]
    Keywords : ;

    Abstract : 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.
