1. 1. Energy supply system for a high-rise building in Germany : Optimization of a heating and cooling supply system made with plant simulations

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Ida Almén; Elin Johansson; [2022]
   Keywords : energy supply system; absorption chiller; compression chiller; Germany;

   Abstract : The building sector has great potential for energy savings since it is responsible for nearly a third of the global energy use. As oil, coal and natural gas continues to hold a big share of the energy mix it is important to work towards introducing more renewable energy alternatives. READ MORE

   Abstract : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). READ MORE

4. 3. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Mantas Petrosius; [2021]
   Keywords : ;

   Abstract : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
