  1. 31. 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.

    University essay from KTH/Energiteknik

    Author : Alessia Accili; [2016]
    Keywords : ;

    Abstract : In line with the article 9 of the EPDB, member states shall ensure that all new public properties are nearly zero energy buildings (n-ZEB) by December 31, 2018. Sports buildings account for a significant share of the European building stock consumption. READ MORE

  6. 35. Analysis of a hybrid heating system with alternative control strategies

    University essay from KTH/Energiteknik

    Author : Glenn STAHRE; [2016]
    Keywords : ;

    Abstract : The potential of a hybrid heating system with the possibility to utilize both district heating and a ground source heat pump is of great interest due to the high prices for district heating in dense populated areas. By controlling a hybrid heating system in a more cost effective manner there might be a possibility to trim the lifetime cost of the entire system. READ MORE
