Design and simulations of Refrigerated Sea Water Chillers with CO2 ejector pumps for marine applications in hot climates
Bodys, Jakub (Master thesis, 2017)According to provided literature review, many investigations concerned improvement possibilities of carbon-dioxide refrigeration units. Basis for further development of this technology are located in environmentally friendly ... -
Design and simulations of refrigerated sea water chillers with CO2 ejector pumps for marine applications in hot climates
Bodys, Jakub; Hafner, Armin; Banasiak, Krzysztof; Smolka, Jacek; Ladam, Yves (Journal article; Peer reviewed, 2018)Various system configurations have been developed to improve the R744 systems under hot ambient conditions. However, stationary land applications are characterised by negligible limits on space for system equipment, unlike ... -

Development of the natural working fluid‐based refrigeration system for domestic scale freeze‐dryer
Piechnik, Edyta; Smolka, Jacek; Palacz, Michał; Tolstorebrov, Ignat; Bodys, Jakub; Ciesielska, Agnieszka; Haida, Michal; Halski, Michal; Stebel, Michal; Melka, Bartlomiej; Nowak, Andrzej J.; Eikevik, Trygve Magne; Allymehr, Ehsan; Bantle, Michael; Claussen, Ingrid Camilla; Hoinka, Krzysztof; Milejski, Adam (Chapter, 2022)In this work, the analysis of the refrigeration system designed for the FrostX 10 freeze‐dryer is presented. The main goal of this study was to experimentally investigate the reference R452a freeze‐dryer and prepare ... -
Experimental and numerical study on the R744 ejector with a suction nozzle bypass
Bodys, Jakub; Smołka, Jacek; Palacz, Michał; Haida, Michal; Banasiak, Krzysztof; Nowak, Andrzej J (Peer reviewed; Journal article, 2021)State-of-the-art R744 cooling cycles include highly efficient ejectors as a crucial element for competitive energy consumption in warm climates. However, an improvement is still possible, as shown in this study. This study ... -
Parallel Work of CO2 Ejectors Installed in a Multi-Ejector Module of Refrigeration System
Bodys, Jakub; Palacz, Michal; Haida, Michal; Smolka, Jacek; Nowak, Andrzej J.; Banasiak, Krzysztof; Hafner, Armin (Journal article; Peer reviewed, 2016)A performance analysis on of fixed ejectors installed in a multi-ejector module in a CO2 refrigeration system is presented in this study. The serial and the parallel work of four fixed-geometry units that compose the ... -
Performance operation of liquid ejectors for a R744 integrated multi-ejector supermarket system using a hybrid ROM
Haida, Michal; Smolka, Jacek; Hafner, Armin; Palacz, Michal; Ostrowski, Zeimowit; Bodys, Jakub; Kriezi, Ekaterini E.; Försterling, Sven; Nowak, Andrzej J.; Banasiak, Krzysztof (Journal article; Peer reviewed, 2019)Performance maps were generated for designed liquid ejectors installed in a multi-ejector module in an R744 integrated supermarket system using a hybrid of the reduced-order model (ROM). Hybrid ROMs of the investigated ...
