Analysis of an integrated heating and cooling system for a building complex with focus on long–term thermal storage
Rohde, Daniel; Andresen, Trond; Nord, Natasa (Journal article; Peer reviewed, 2018)Modern building complexes have simultaneous heating and cooling demands. Therefore, integrated energy systems with heat pumps and long-term thermal storage are a promising solution. An integrated heating and cooling system ... -
Analysis of the Trilateral Flash Cycle for Power Production from low Temperature Heat Sources
Trædal, Stian (Master thesis, 2014)SummaryIn this study, the Trilateral Flash Cycle (TFC) and the Partially Evaporating Cycle (PEC) have been analyzed and compared to the Organic Rankine Cycle (ORC) for power production from low temperature heat sources. ... -
Compact steam bottoming cycles: minimum weight design optimization and transient response of once through steam generators
Mocholí Montañés, Rubén; Skaugen, Geir; Hagen, Brede; Rohde, Daniel (Peer reviewed; Journal article, 2021)Compactness and weight minimization are key aspects for successful and widespread implementation of waste heat recovery steam cycles in off-shore oil and gas platforms due to the site weight and volume footprint constraints. ... -
Documentation of an integrated thermal energy system for a building complex
Rohde, Daniel; Bantle, Michael; Andresen, Trond; Nord, Natasa (Chapter, 2015)In large buildings and building complexes, energy use can be reduced by efficient interaction between heating and cooling demands and thermal storage (short and long term storage). This work describes an integrated energy ... -
Dynamic modeling of local district heating grids with prosumers: A case study for Norway
Kauko, Hanne; Kvalsvik, Karoline Husevåg; Rohde, Daniel; Nord, Natasa; Utne, Åmund (Journal article; Peer reviewed, 2018)District heating (DH) will play an important role in the future fossil-free energy systems by enabling increased utilization of waste heat and renewable heat sources to cover buildings' heat demand. A prerequisite for this ... -
Dynamic modelling of local low-temperature heating grids: A case study for Norway
Kauko, Hanne; Kvalsvik, Karoline Husevåg; Rohde, Daniel; Hafner, Armin; Nord, Natasa (Journal article; Peer reviewed, 2017)Today's district heating (DH) networks in Norway are 2nd and 3rd generation systems, with supply temperatures ranging from 80 to 120 °C. In new developments, it is desirable to shift to 4th generation, low-temperature ... -
Dynamic optimization of control setpoints for an integrated heating and cooling system with thermal energy storages
Rohde, Daniel; Knudsen, Brage Rugstad; Andresen, Trond; Nord, Natasa (Journal article; Peer reviewed, 2019)Energy systems for buildings and neighborhoods are expected to become more complex and flexible. Advanced control strategies are required to exploit the full potential of this flexibility and are especially important for ... -
Dynamic simulation of future integrated energy systems
Rohde, Daniel (Doctoral theses at NTNU;2019:213, Doctoral thesis, 2019)The building sector is responsible for a large part of the world's total energy use. More than half of building energy use is needed for space heating, domestic hot water heating, and space cooling. Thermal energy supply ... -
Energy Recovery From Furnace Off-Gas: Analysis of an Integrated Energy Recovery System by Means of Dynamic Simulation
Rohde, Daniel; Andresen, Trond; Zotica, Cristina; Wilpert, Paul (Chapter, 2020)Surplus heat recovery and electricity generation from furnace off-gas has been implemented at several silicon and ferro-alloy plants in Norway. There is likely significant potential for improvement of both technology ... -
