Energy efficient and climate friendly refrigeration systems onboard fishing vessels
Widell, Kristina Marianne Norne; Gabrielii, Cecilia H; Söylemez, Engin; Hazarika, Mihir Mouchum; Hafner, Armin; Khan, Muhammad Umar; Svendsen, Eirik Starheim; Nordtvedt, Tom Ståle; Tolstorebrov, Ignat; Pachai, Alexander C. (Chapter, 2023)Refrigeration systems onboard fishing vessels are necessary to keep the catch at a low temperature and to ensure long shelf life. Most refrigeration systems in the world fishing fleet still have R-22 as a working fluid, ... -
Greenhouse Gas Emission and Energy Production from a Ground-Mounted Solar Park
Langås, Anja Irene; Sæternes, Solveig Hegstad; Tveit, Helene Sæle (Bachelor thesis, 2023)I lys av klimaendringene er det behov for en rask omstilling og overgang fra fossile energikilder til fornybar energi som solenergi. I en verden hvor bærekraftig utvikling er essensielt, blir det viktig å adressere den ... -
Hybrid park at Stokkfjellet; Combining solar and wind power in the same grid
Huse, Elias; Grindahl, Johanne; Nergård, Gro Letnes (Bachelor thesis, 2023)Denne oppgaven analyserer tre alternativer for drift av en foreslått hybridpark ved et allerede eksisterende vindkraftverk på Stokkfjellet. Dette gjøres ved å simulere et PV-system og utforske tre forskjellige scenarioer ... -
Integration of a cold thermal energy storage into an existing refrigeration system
de Vries, Mattis (Master thesis, 2024)Denne masteroppgaven undersøker integreringen av et termisk energilagringssystem i et eksisterende kjølesystem, og dekker både simuleringen av kjølesystemet og den praktiske implementeringen av et cold thermal energy storage ... -
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 ... -
Performance analysis of a CO2-ice heat pump
Söylemez, Engin; ERB, Kevin; Schubert, Maike; Gerber, Raphael; Carbonell, Daniel; Hazarika, Mihir Mouchum; Hafner, Armin (Chapter, 2023) -
The Performance Analysis of an Integrated CO2 Refrigeration System with Multi-Ejectors Installed in a Supermarket
Söylemez, Engin; Hafner, Armin; Schlemminger, Christian; Kriezi, Ekaterini E.; Khorshidi, Vahid (Peer reviewed; Journal article, 2022)The field data from an integrated CO2 refrigeration system installed in a supermarket located north of the capital of Lisbon was analyzed. The goal was to demonstrate the effect and performance of multi-ejectors on a ... -
Performance of integrated R744-packs part 1: compressor mass flow estimation based on data-driven models using analytical methods and actual field measurements
Khorshidi, Vahid; Kriezi, Ekaterini E.; Schlemminger, Christian; Hafner, Armin; Söylemez, Engin (Chapter, 2021)Rising concerns for climate change impacts along with the new legislation aimed at lowering emissions indicates the inevitable transition in the cooling/heating industry towards a more energy-efficient solution with minimal ... -
Simulation of a carbon dioxide (R-744) refrigeration system for fishing vessel
Semaev, Pavel; Söylemez, Engin; Tolstorebrov, Ignat; Hafner, Armin; Widell, Kristina Norne; Lund, Thomas; Øy, Jostein; Urke, Jan Petter (Chapter, 2021)The paper describes architecture of a prototype industrial CO2 trans-critical system for production of refrigerated sea water (RSW) for either fishing vessels or land-based process plants. The refrigeration system was ...
