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} } @inproceedings{LippelBeckerZielke2019, author = {Lippel, Jens and Becker, Martin and Zielke, Thomas}, title = {Modeling Dynamic Processes with Deep Neural Networks: A Case Study with a Gas-fired Absorption Heat Pump}, series = {SIMULTECH 2019: Proceedings of the 9th International Conference on Simulation and Modeling Methodologies, Technologies and Applications : Prague, Czech RepublicJuly 29-31, 2019}, booktitle = {SIMULTECH 2019: Proceedings of the 9th International Conference on Simulation and Modeling Methodologies, Technologies and Applications : Prague, Czech RepublicJuly 29-31, 2019}, editor = {Obaidat, Mohammad S. and {\"O}ren, Tuncer and Szczerbicka, Helena}, publisher = {INSTICC}, isbn = {978-989-758-381-0}, doi = {10.5220/0007932903170326}, pages = {317 -- 326}, year = {2019}, language = {en} } @article{NebelSchmidtPanetal.2019, author = {Nebel, Janine and Schmidt, Stefan and Pan, Qiushi and Lotz, Katrin and Kaluza, Stefan and Muhler, Martin}, title = {On the role of cobalt carbidization in higher alcohol synthesis over hydrotalcite-based Co-Cu catalysts}, series = {Chinese Journal of Catalysis}, volume = {40}, journal = {Chinese Journal of Catalysis}, number = {11}, publisher = {Elsevier}, issn = {1872-2067}, doi = {10.1016/S1872-2067(19)63344-9}, pages = {1731 -- 1740}, year = {2019}, language = {en} } @inproceedings{NeefAndre2019, author = {Neef, Matthias and Andr{\´e}, Baier}, title = {Blue Engineering: Ingenieur_innen mit {\"o}kologischer und sozialer Verantwortung - ein Studierenden-getriebenes, modulares Seminar-Konzept}, series = {DGHD-Jahrestagung}, booktitle = {DGHD-Jahrestagung}, publisher = {Universit{\"a}t Leipzig}, address = {Leipzig}, organization = {Universit{\"a}t Leipzig}, year = {2019}, language = {de} } @incollection{NiemannFusseneckerSchloesser2019, author = {Niemann, J{\"o}rg and Fussenecker, Claudia and Schl{\"o}sser, Martin}, title = {Eye Tracking for Quality Control in Automotive Manufacturing}, series = {Systems, Software and Services Process Improvement}, booktitle = {Systems, Software and Services Process Improvement}, editor = {Walker, Alastair and O'Connor, Rory V. and Messnarz, Richard}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {978-3-030-28004-8}, doi = {10.1007/978-3-030-28005-5_22}, pages = {289 -- 298}, year = {2019}, language = {en} } @article{PfeiffelmannBenimJoos2019, author = {Pfeiffelmann, Bj{\"o}rn and Benim, Ali Cemal and Joos, Franz}, title = {A Finite Volume Analysis of Thermoelectric Generators}, series = {Heat Transfer Engineering}, volume = {40}, journal = {Heat Transfer Engineering}, number = {17-18}, publisher = {Taylor \& Francis}, issn = {0145-7632}, doi = {10.1080/01457632.2018.1474588}, pages = {1442 -- 1450}, year = {2019}, language = {en} } @inproceedings{RoedderSpiegelFranketal.2019, author = {R{\"o}dder, Maximilian and Spiegel, Thomas and Frank, Lena and Neef, Matthias and Adam, Mario}, title = {Integration eines multifunktionalen W{\"a}rmepumpensystems als Hardware-in-the-Loop in ein Niederspannungsnetzmodell}, series = {Smart Energy and Systems 2019: Digitalisierung - Anwendungen in Technik und Industriegesellschaft, 10.
