System model derivation of the CO2 two-phase ejector based on the CFD-based reduced-order model
Haida, Michal; Smolka, Jacek; Hafner, Armin; Ostrowski, Zeimowit; Palacz, Michal; Nowak, Andrzej J.; Banasiak, Krzysztof (Journal article; Peer reviewed, 2018)The developed reduced-order model (ROM) of the R744 two-phase ejector was presented in this paper. The proper orthogonal decomposition (POD) model was employed together with the radial basis function (RBF) to evaluate the ... -
Testing of tri-partite CO2 gas cooler prototype for domestic hot water and space heating
Tolstorebrov, Ignat; Zendehboudi, Alireza; Banasiak, Krzysztof; Köster, Lukas; Álvarez Pardiñas, Ángel; Hafner, Armin (Science et technique du froid;, Chapter, 2020)The aim of this study was to test a tri-partite gas cooler for CO2 heat pumps (5-13 kW). The proposed heat exchanger allowed the simultaneous and separate production of space heating and domestic hot water with an integrated ... -
The R744 multi-ejector hybrid CFD and experimentally-based reduced-order model
Haida, Michal; Smolka, Jacek; Hafner, Armin; Palacz, Michal; Ostrowski, Zeimowit; Madsen, Kenneth B.; Försterling, Sven; Nowak, Andrzej J.; Banasiak, Krzysztof (Science et technique du froid;2018-3, Chapter; Peer reviewed, 2018) -
Thermodynamic Performance Investigation of Commercial R744 Booster Refrigeration Plants Based on Advanced Exergy Analysis
Gullo, Paride; Hafner, Armin; Banasiak, Krzysztof (Journal article; Peer reviewed, 2019)After the recent renewed interest in CO2 as the refrigerant (R744) for the food retail industry, many researchers have focused on the performance enhancement of the basic transcritical R744 supermarket refrigeration unit ... -
Transcritical R744 refrigeration systems for supermarket applications: Current status and future perspectives
Gullo, Paride; Hafner, Armin; Banasiak, Krzysztof (Journal article; Peer reviewed, 2018)Visible signs of climate change call for urgent actions on food retail industry, since such a sector is characterized by an abundant carbon footprint. Being CO2 (or R744) recognised across the world as the most promising ...
