The most promising concepts are Organic Rankine Cycles (ORC) and Steam Rankine Cycles (SRC). In previous work of the Center of Innovative Energy Systems, D{\"u}sseldorf (Germany), the technical and economic feasibility of a low pressure SRC has been investigated and the advantages in comparison to organic Rankine cycles are highlighted. A distinctive feature of the cycle is the use of the ICE coolant heat for evaporation, which limits the cycles maximum steam pressure to values below atmospheric pressure. This work presents first results of a test rig with data reconciliation according to DIN 2048 to validate the simulation results and design calculations. As a basis for the experimental investigations, a gas fired CHP plant was selected. The design of the test rig is optimized for the operation in the laboratory, where the coolant heat is emulated by a tempering device and the exhaust heat of the CHP plant is emulated by a gas burner. With the designed test rig, it is possible to control the volume flow and the temperatures of the coolant and exhaust gas, so that different load conditions of the gas fired CHP plant can be investigated. For initial tests, the turbine in the SRC is replaced by a throttle to achieve the pressure drop of the turbine. The experimental results show, that the exhaust and coolant heat of a 36 kWel CHP plant can be emulated and the performance expectations of the cycle can be met in stable steady-state conditions. Based on the measurement results and the turbine design calculations an electric power output of the cycle of 3.8 kW will be possible, which results in a cycle efficiency of about 6.5 \% and an increase of the electrical power output of the CHP plant of about 10 \%. The results show that the plant concept is technically feasible and, with further optimization, also represents an alternative to ORC plants in terms of increasing the efficiency of a cogeneration plant.}, language = {en} } @article{WolterZekornNeef2016, author = {Wolter, Nina and Zekorn, Thomas and Neef, Matthias}, title = {Station{\"a}re thermodynamische Prozesssimulationen am Beispiel eines Industriekraftwerks}, series = {BWK: das Energie-Fachmagazin}, volume = {68}, journal = {BWK: das Energie-Fachmagazin}, number = {6}, pages = {6 -- 10}, year = {2016}, abstract = {Um bauliche Ver{\"a}nderungen in bestehenden Kraftwerksprozessen auf ihre Wirkungsweise untersuchen und thermodynamisch beziehungsweise wirtschaftlich bewerten zu k{\"o}nnen, werden thermische Kraftwerksprozesse mit geeigneter Simulationssoftware abgebildet und in verschiedenen Detaillierungsstufen ausgelegt oder nachgerechnet.

Due to the wide range of organic working fluids available the fluid selection adds an additional degree-of-freedom to the early design phase of an ORC process. Despite thermodynamic aspects such as the temperature level of the heat source, other technical, economic, and safety aspects have to be considered. For the fluid selection process in this paper, 22 criteria were identified in six main categories while distinguishing between elimination (EC) and tolerance criteria (TC). For an ORC design, the suggested method follows a practical engineering approach and can be used as a structured way to limit the number of interesting working fluids before starting a detailed performance analysis of the most promising candidates. For the first time, the selection process is applied to a two-stage reference cycle, which uses the waste heat of a large reciprocating engine for cogeneration power plants. It consists of a high temperature (HT) and a low temperature (LT) cycle in which the condensation heat of the HT cycle provides the heat input of the LT cycle. After the fluid selection process, the detailed thermodynamic cycle design is carried out with a thermodynamic design tool that also includes a database for organic working fluids. The investigated ORC cycle shows a net thermal efficiency of about 17.4\% in the HT cycle with toluene as the working fluid and 6.2\% in LT cycle with isobutane as the working fluid. The electric efficiency of the cogeneration plant increases from 40.4\% to 46.97\% with the both stages of the two-stage ORC in operation.}, language = {en} } @article{NeefZielkeFussenecker2017, author = {Neef, Matthias and Zielke, Thomas and Fussenecker, Claudia}, title = {„Engineering Conferences": Wissenschaftlich Kommunizieren im Master}, series = {Die Neue Hochschule}, volume = {58}, journal = {Die Neue Hochschule}, number = {3}, pages = {4}, year = {2017}, language = {de} } @article{BonkLauxRoedderetal.2017, author = {Bonk, Christian Dirk and Laux, Christoph and R{\"o}dder, Maximilian and Neef, Matthias}, title = {Design of a 1 KW Organic Rankine Cycle for Teaching and Research Issues}, series = {Energy Procedia}, volume = {129}, journal = {Energy Procedia}, publisher = {Elsevier}, doi = {10.1016/j.egypro.2017.09.117}, pages = {931 -- 938}, year = {2017}, abstract = {This paper deals with the design of a micro-scale ORC plant for teaching and research including the development of an automated control concept. The aim is to provide a safe and environmentally acceptable micro-scale heat engine, which can be developed, implemented and used in university labs for the education of students as well as for small research projects. The test rig allows the support of several learning outcomes on a multi-disciplinary level particularly for the implementation and simulation of small power systems. Special attention was given to the organic working fluid characteristics and its selection process. In addition to the above-mentioned performance goals, favourable safety properties and low global warming potential were decisive in the selection of the novel organic fluid called 3M™ Novec™ 649. The performance and the fluid behaviour of Novec 649 in a micro-scale power cycle are of major interest and the research goal for the test rig presented in this paper. Due to the expected power output of 1 kW, a scroll expander was chosen as the generator drive for the micro plant. In order to design the major parts of the ORC, the thermodynamic simulation software EBSILON®Professional was used. The supply temperature was set to 140 °C. As a result of the simulation, feasible expander inlet pressures spread from 5.5 bar to 8.5 bar. This leads to thermal efficiencies of the ORC in the order of 5 \%. Adding a recuperator to the cycle system decreases the operating pressure range but in the end, the thermal efficiency can be increased by 1.5 \%-points up to 6.2 \%. Finally, an automated control concept is introduced, where the pump is controlled via the fill level measurement system.}, language = {en} } @misc{FrankRoedderNeefetal.2018, author = {Frank, Lena and R{\"o}dder, Maximilian and Neef, Matthias and Adam, Mario}, title = {Heizung, L{\"u}ftung, Weiße Ware - Ein integriertes Systemkonzept f{\"u}r das Haus der Zukunft}, series = {KI K{\"a}lte Luft Klimatechnik}, volume = {54}, journal = {KI K{\"a}lte Luft Klimatechnik}, number = {11}, publisher = {H{\"u}thig}, issn = {1865-5432}, pages = {50 -- 56}, year = {2018}, abstract = {In energieeffizienten Geb{\"a}uden spielt der Bedarf an Energie f{\"u}r die Raumheizung gegen{\"u}ber der ben{\"o}tigten Energie f{\"u}r Warmwasser und zum Antrieb elektrischer Ger{\"a}te eine zusehends untergeordnete Rolle.

To prepare leading edge serrations for industrial application, two obstacles remain to be addressed. First is a combined analysis of the aeroacoustic and the aerodynamic performance of leading edge serrations to develop optimum designs. Second is the need to examine the transferability of the known effects of leading edge serrations from a single aerofoil to full rotors, which are considered to be the final area of application. This thesis aims to assist in the transfer of a well-investigated aerofoil with serrated leading edges from the rigid to the rotating domain. With this purpose, a single aerofoil type is selected and thoroughly analysed, experimentally and numerically, to generate a reliable data basis for aerodynamic performance and noise reduction capability. Aside from gathering information on the overall performance, the spatial distribution of the noise sources is localised, and the spectral composition of the noise reduction is found to follow a clearly defined scaling law. Aerodynamically, generated vortices are found to be responsible for a complex three-dimensional separation mechanism of the leading edge serrations, causing a delay of stall. The generated data basis is then used to design low-pressure axial fans of minimum complexity by keeping the initially chosen aerofoil type. The experimentally identified noise reduction mechanisms for the serrated axial fans are found to be more diverse than the single aerofoil and highly dependent on the inflow conditions and the operation point of the fan. A highly similar pattern for the spectral scaling of the noise reduction supports the finding that at optimum operation conditions, the previously identified noise reduction mechanisms for the single aerofoils are transferable to the rotating domain. On the other hand, additional aerodynamic mechanisms are found to dominate the noise reduction for the instability region of the fan, also contributing to reduced blade-to-blade interaction effects. Moreover, the blade-tip leakage flow is altered by delaying the development of coherent structures. The next step towards a more general description of the aeroacoustic and aerodynamic dependencies is developing a comprehensive model based on artificial neural networks. This model allows a combined analysis of the aerodynamic and acoustic performance of rotors with serrated leading edges and shows an accurate prediction of the overall performance and the spectral composition of the radiated noise. It also enables the development of multi-objective optima for serration designs and motivates further studies into the generalisability of the observed trends. Furthermore, the developed model represents a feasible tool to create tailored serration designs for maximum efficiency in both aeroacoustics and aerodynamics, contributing to the development of future low-noise fans and rotating machinery.}, language = {en} } @techreport{Vogel2019, author = {Vogel, Peter}, title = {Investieren unter Nebenbedingungen - Teil 3: Erweiterung der Statistik}, publisher = {Hochschule D{\"u}sseldorf}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, issn = {2567-2347}, doi = {10.20385/2567-2347/2019.3}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-20373}, pages = {59}, year = {2019}, abstract = {Der dritte Teil der Schriftenreihe entwickelt die statistische Beschreibung f{\"u}r das Investieren in Wertpapiere weiter, welche in den ersten beiden Teilen begonnen wurde.

These implications should be taken into consideration by policy makers when developing legislation and regulations addressing the building sector. A parametric analysis was conducted on six buildings in Europe of different typologies and climates in order to assess how different weighting factors would impact the choice of technical systems to be installed. For each combination the amount of PV capacity necessary to achieve a net zero balance has been calculated and used as the main indicator for comparison; where less PV area means more favourable condition. The effect of including a solar thermal system is also discussed. With the current European national weighting factors, biomass boiler is largely the preferred solution, frequently achieving the balance with PV installed on the roof, while gas boiler is the most penalized. The situation changes when strategic weighting factors are applied. Lower weighting factors for electricity and district heating, e.g. reflecting national targets of increased penetration of renewables in such grids, would promote the use of heat pump and district heating, respectively. Asymmetric factors aimed at rewarding electricity export to the grid would facilitate the achievement of the zero balance for all technologies, promoting cogeneration in some cases. On the contrary, low weighting factors for electricity, e.g. reflecting a scenario of high decarbonisation of the power system, prove quite demanding; only few technical solutions would be able to reach the balance within the available roof area for PV, because of the low value credited to exported electricity. In this situation, the preferred solution would be heat pumps combined with solar thermal. In addition, the choice of weighting factors and the resulting favoured technologies will determine the temporal matching of load and generation. While all-electric solutions tend to use the grid as seasonal storage, other solutions will have a yearly net export of electricity to the grid to compensate for the supply of other (thermal) energy carriers. Therefore, it is important to consider the implications for the electricity grid resulting from the choice of weighting factors.}, language = {en} } @article{MusallVoss2014, author = {Musall, Eike and Voss, Karsten}, title = {Renewable Energy Ratio in Net Zero Energy Buildings}, series = {REHVA Journal}, volume = {51}, journal = {REHVA Journal}, number = {3}, publisher = {REHVA}, pages = {14 -- 18}, year = {2014}, language = {en} } @incollection{VossMusallSartorietal.2013, author = {Voss, Karsten and Musall, Eike and Sartori, Igor and Lollini, Roberto}, title = {Nearly Zero, Net Zero, and Plus Energy Buildings - Theory, Terminology, Tools, and Examples}, series = {Transition to renewable energy systems}, booktitle = {Transition to renewable energy systems}, editor = {Stolten, Detlef and Scherer, Viktor}, publisher = {Wiley}, address = {Weinheim}, isbn = {978-3-527-33239-7}, doi = {10.1002/9783527673872.ch41}, pages = {875 -- 889}, year = {2013}, language = {en} } @incollection{VossMusall2013, author = {Voss, Karsten and Musall, Eike}, title = {Energiebilanzierung}, series = {Zero: Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, booktitle = {Zero: Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, editor = {B{\"u}rgi, Hanspeter and Hall, Monika and Hari, Bruno and Huber, Manfred and Musall, Eike and R{\"u}egg, Ruedi and T{\"o}dtli, J{\"u}rg and Voss, Karsten and Witzig, Andreas and Bernhard, Soara and Humm, Othmar and Otto, Julius}, publisher = {Faktor Verlag}, address = {Z{\"u}rich}, isbn = {978-3-905711-22-6}, pages = {16 -- 27}, year = {2013}, language = {de} } @misc{OPUS4-2014, title = {Net Zero Energy Buildings: International Projects of Carbon Neutrality in Buildings}, volume = {Detail green books}, editor = {Voss, Karsten and Musall, Eike}, publisher = {De Gruyter}, address = {Berlin}, isbn = {3920034805}, year = {2013}, language = {en} } @techreport{NorisAssuntaLollini2013, author = {Noris, Federico and Assunta, Napolitano and Lollini, Roberto}, title = {Measurement and Verification protocol for Net Zero Energy Buildings: A report of Subtask A - IEA Task 40/Annex 52 Towards Net Zero Energy Solar Buildings}, series = {International Energy Agency IEA - SHC Task 40 / ECBCS Annex 52}, journal = {International Energy Agency IEA - SHC Task 40 / ECBCS Annex 52}, address = {Bozen}, year = {2013}, language = {en} } @incollection{Musall2013, author = {Musall, Eike}, title = {Querschnitt gebauter Beispiele}, series = {Zero: Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, volume = {Schriftenreihe Technik}, booktitle = {Zero: Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, editor = {B{\"u}rgi, Hanspeter and Hall, Monika and Hari, Bruno and Huber, Manfred and Musall, Eike and R{\"u}egg, Ruedi and T{\"o}dtli, J{\"u}rg and Voss, Karsten and Witzig, Andreas and Bernhard, Soara and Humm, Othmar and Otto, Julius}, publisher = {Faktor Verlag}, address = {Z{\"u}rich}, isbn = {978-3-905711-22-6}, pages = {34 -- 49}, year = {2013}, language = {de} } @incollection{Musall2013, author = {Musall, Eike}, title = {Geschichte einer Idee}, series = {Zero.Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, booktitle = {Zero.Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, editor = {Faktor Verlag,}, publisher = {Faktor Verlag}, address = {Z{\"u}rich}, isbn = {978-3-905711-22-6}, pages = {10 -- 21}, year = {2013}, language = {de} } @incollection{Musall2013, author = {Musall, Eike}, title = {Architektonische Merkmale}, series = {Zero.Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, booktitle = {Zero.Konzepte f{\"u}r Null- und Plusenergieh{\"a}user}, editor = {Faktor Verlag,}, publisher = {Faktor Verlag}, address = {Z{\"u}rich}, isbn = {978-3-905711-22-6}, pages = {68 -- 77}, year = {2013}, language = {de} } @techreport{HermelinkSchimscharBoermansetal.2013, author = {Hermelink, Andreas and Schimschar, Sven and Boermans, Thomas and Pagliano, Lorenzo and Zangheri, Paolo and Armani, Roberto and Voss, Karsten and Musall, Eike}, title = {Towards nearly zero-energy buildings}, editor = {Ecofys by order of European Commission,}, publisher = {Europ{\"a}ische Kommission}, address = {K{\"o}ln}, organization = {Europ{\"a}ische Kommission}, year = {2013}, language = {en} }
