1. 1. Solar Photovoltaic Thermal Collectors and Ground Source Heat Pumps for Commercial Buildings : Case study in Sweden

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

   Author : Doris Dijak; Elin Torstensson; [2023]
   Keywords : Ground Source Heat Pump; Photovoltaic Thermal Collectors; Borehole Thermal Energy Storage; Free Cooling.; Bergvärmepumpssystem; Termiska Solceller; Borrhålsbaserade Termiska Energilager; Frikyla.;

   Abstract : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

3. 2. Harmonisk strömsimulering i inverterbaserade värmepumpar

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alexander Magnusson; [2023]
   Keywords : Current harmonics; inverter-driven compressor; black box simulation;

   Abstract : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. READ MORE

4. 3. Model Predictive Control for Ground Source Heat Pumps : Reducing cost while maintaining comfort

   University essay from Linköpings universitet/Reglerteknik

   Author : Isak Bokne; Charlie Elf; [2023]
   Keywords : MPC; Model Predictive Control; heat pump control; electricity spot price; weather prediction; reducing cost;

   Abstract : Today, the control of heat pumps aims to first and foremost maintain a comfortable indoor temperature. This is primarily done by deciding input power based on outside temperature. The cost of electricity, which can be rather volatile, is not taken into account. READ MORE

5. 4. Dynamic Modeling of Heat Power System : Modeling of a Heat Power System Using Physical and Data-driven Methods and Investigation of a Moving Boundary Method

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Albin Gustafsson; [2023]
   Keywords : System identification; Dynamic modeling; Organic Rankine cycle; Moving boundary; Thermodynamics.; System identifikation; Dynamisk modellering; Organisk Rankinecykel; Rörliga randvillkor; Termodynamik.;

   Abstract : Our society is becoming more and more electrified every day. However, a significant portion of the world’s electricity generation relies on the combustion of fossil fuels to produce heat, which is subsequently harnessed to generate electricity. One way of generating electricity from heat is by utilizing a Rankine cycle. READ MORE

6. 5. Modeling for characterization of continuous casting simulator using CFD

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Filip Reineholm-Hult; [2023]
   Keywords : Continuous casting; CFD; computational fluid dynamics;

   Abstract : In order to improve the continuous casting process of steel, it’s important to have an understanding of the fuid mechanics of the casting process. As experiments on a real caster are usually impractical, both physical and numerical modeling are important for creating this understanding. READ MORE
