1. 1. HEAT CONSUMPTION OPTIMIZATION IN 4TH GENERATION DISTRICT HEATING : Study on utilizing low temperature heat sources and heat stored in a house by varying indoor temperature

   Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Framtidens energi

   Författare :Simon Karlsson; Farman Farman; [2023]
   Nyckelord :4th Generation District Heating; Heat Pumps; Thermal Energy Storage; Optimization; Low Temperature Heat Sources; Thermal Inertia;

   Sammanfattning : 4th generation district heating (4GDH) and varying the indoor temperature to store heat are both important concepts that can make it easier to implement more renewable energy and reduce costs of heating. This study looks at these concepts from a customer perspective using one building and looking at how energy can be stored and the performance of 4GDH. LÄS MER

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

   Författare :Oskar Olsson; [2023]
   Nyckelord :4th generation district heating; distribution systems; simulation; energy efficiency; cascading;

   Sammanfattning : In Europe, the prices of natural gas and electricity reached an all-time high during 2022. An approach tomitigate these high prices is to expand the district heating systems in urban areas, this will reduceelectric load as well as to increase the power production in combined heat and power plants.

   Sammanfattning : The world is constantly striving towards a more sustainable living, where every part of contribution is greatly appreciated. When it comes to heating of buildings, district heating is often the main source of heat. During specific times, peak demands are created by the tenants who are demanding a lot of heat at the same time. LÄS MER

7. 5. EctogridTM : The competitiveness of a low temperature district heating network in Germany and United Kingdom

   Master-uppsats, KTH/Tillämpad termodynamik och kylteknik
