Cold thermal energy storage with low-temperature plate freezing of fish on offshore vessels
Verpe, Espen Halvorsen; Tolstorebrov, Ignat; Sevault, Alexis; Hafner, Armin; Ladam, Yves (Chapter, 2019)This paper presents the results of a numerical and experimental study of freezing time for fish in plate freezers, and the potential for improvement by altering fish block thickness and lowering evaporation temperature. ... -
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 ... -

Life Cycle Assessment of Electricity Generation from Low Temperature Waste Heat: The Influence of Working Fluid
Bai, Lijun (Master thesis, 2012)In the metallurgical industry and in refineries and process industries, there is significant amount of waste heat, it is a challenged field to do the research for producing electricity from the energy of waste heat. ... -
Overview of the development and status of carbon dioxide (R-744) refrigeration systems onboard fishing vessels
Söylemez, Engin; Widell, Kristina Norne; Gabrielii, Cecilia H; Ladam, Yves; Lund, Thomas; Hafner, Armin (Peer reviewed; Journal article, 2022)Globally, most fishing vessels still use the ozone-depleting and climate-harmful R-22 in their freezing and refrigerated seawater (RSW) systems. However, in some regions, the natural refrigerant ammonia is the preferred ... -
Power Production from Low Temperature Heat Sources
Midtsjø, Alexander (Master thesis, 2009)As part of the energy recovery part of the ROMA (Resource Optimization and recovery in the Materials industry) project, a laboratory prototype power production system is being built and completed in 2009. The laboratory ... -
Varmegjenvinning i fryseanlegg med bruk av ejektorsystem
Hundseth, Øystein (Master thesis, 2011)I denne studien er en forsøksrigg konstruert for å undersøke en ejektorkrets med CO2 som kuldemedie. Disse forsøksdataene blir videre benyttet for å beregne energieffektiviseringspotensialet ved å implementere et ejektorsystem ...
