Energy consumption of ammonia refrigeration system on board a fishing vessel
Svendsen, Eirik Starheim; Widell, Kristina Norne; Nordtvedt, Tom Ståle; Jafarzadeh, Sepideh; Gabrielii, Cecilia H (Sciences et technique du froid;, Chapter; Peer reviewed, 2021)When assessing the carbon footprint of seafood from capture fisheries, the fuel use during fishing operation is the major contributor to overall greenhouse gas emissions. While the necessary shift towards low-carbon fuels ... -
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, ... -
Heat pump/chiller system for centralized kitchens in India
Singh, Simarpreet; Hafner, Armin; Banasiak, Krzysztof; Seshadri, Satyanarayanan; Maiya, Prakash; Smitt, Silje Marie; Gabrielii, Cecilia H (Science et technique du froid;, Chapter, 2020)A heat pump unit using CO2 as working fluid is designed to meet not only a part of the heating demand in the centralised kitchen at The Akshaya Patra Foundation, Bengaluru, India, but also the entire cooling demand to ... -
Heat-driven snow production applying ejector and natural refrigerant
Aasen, Ailo; Gabrielii, Cecilia H; Moen, Ole Marius (Science et technique du froid;, Chapter; Peer reviewed, 2022)An effect of climate change is fewer cold days and less natural snow at lower elevations. This has spurred the interest in temperature independent snow (TIS) production, i.e., refrigeration technologies that can produce ... -
Implementation of natural refrigerants on cruise ships. A review of rules and regulations from two Classification Societies
Álvarez Pardiñas, Ángel; Gabrielii, Cecilia H (SINTEF Energi. Rapport;, Research report, 2022)This report delves into the challenge of implementing heat pumps, refrigeration systems and chillers (vapour compression systems) that use natural refrigerants, in the maritime sector. The first part gives a context, ... -
Innovative refrigeration concept for passenger ships - combining CO2 refrigerant, cold recovery and cold storage
Pardiñas, Ángel Á.; Selvnes, Håkon; Gabrielii, Cecilia H; Saeed, Muhammad Zahid (Science et technique du froid;, Chapter; Peer reviewed, 2022)More stringent international regulations on ship's emissions require a shift towards more climate friendly fuels, such as liquefied natural gas (LNG). On LNG-driven ships, the fuel is stored onboard at cryogenic temperature. ... -
