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

   University essay from Mälardalens universitet/Framtidens energi

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

   Abstract : 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. READ MORE
