    • Cryogenic cold utilization and system integration possibilities for LNG-driven fishing vessels 

      Saeed, Muhammad Zahid; Widell, Kristina Norne; Hafner, Armin; Nordtvedt, Tom Ståle; Svendsen, Eirik Starheim (Chapter, 2020)
      Liquified natural gas (LNG) fuelled vessels are increasing in the fishing industry due to its reduced environmental footprint as compared to vessels using heavy hydrocarbon fuels. Cryogenic tanks are used to store LNG on ...

    • 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, ...

    • Energy flow analysis of a poultry process plant 

      Svendsen, Eirik Starheim (Master thesis, 2019)
      Industriell prosessering av mat innebærer ofte en del forskjellige termiske prosesser som er nødvendige for å gjøre maten trygg for oss mennesker. For bedrifter som produserer og foredler mat betyr dette at de må ha komplekse ...

    • Energy flow analysis of a poultry processing plant 

      Svendsen, Eirik Starheim; Hafner, Armin; Selvnes, Håkon; Widell, Kristina Norne (Chapter, 2020)
      More efficient utilization of primary energy resources can be achieved with thermal energy storages and it is a measure to limit global warming. The thermal energy demands of industrial food-processing plants are non-uniform ...

    • Energy flow analysis of an industrial ammonia refrigeration system and potential for a cold thermal energy storage 

      Widell, Kristina Norne; Svendsen, Eirik Starheim; Selvnes, Håkon; Sevault, Alexis; Hafner, Armin; Nordtvedt, Tom Ståle (Chapter, 2022)
      There is an increasing effort to reduce energy demand at food processing plants, mainly to reduce the total carbon footprint. The energy demand of a fish processing plant (using ammonia as refrigerant) has been evaluated ...

    • Integrated thermal storage and heat recovery of the CO2 refrigeration system for fishing vessels 

      Saeed, Muhammad Zahid; Widell, Kristina Norne; Hafner, Armin; Nordtvedt, Tom Ståle; Svendsen, Eirik Starheim (Chapter, 2020)
      The natural refrigerant CO2 is gaining an attraction for fishing vessels due to its compact units, negligible global warming potential (GWP), and non-toxic behaviour. Chilling and freezing onboard are energy-consuming ...

    • Integration of Cold Thermal Energy Storage at a Pelagic Fish Processing Plant: A Modelling Approach 

      Svendsen, Eirik Starheim; Bengsch, Jan; Widell, Kristina Marianne Norne; Selvnes, Håkon; Sevault, Alexis Gerard Edouard; Hafner, Armin; Nordtvedt, Tom Ståle (Chapter, 2023)
      Energy intensive sectors such as food processing are paying more and more attention towards energy conservation and reducing their total carbon footprint. The energy demand of a pelagic fish processing plant has been ...

    • Integration of gravity-fed evaporators in CO2 based heat-pump chillers 

      Hazarika, Mihir Mouchum; Bengsch, Jan; Hafsås, Johan; Hafner, Armin; Svendsen, Eirik Starheim; Ye, Zuliang (Chapter, 2022)
      This study is carried out to model a gravity-fed evaporator for CO2 based heat-pump chillers. The gravity-fed evaporator loop consists of a separator, a downcomer, a heat exchanger, and a riser. The working principle is ...

    • Performance of high temperature heat pump for simultaneous and efficient production of ice water and process heat 

      Schlemminger, Christian; Svendsen, Eirik Starheim; Foslie, Sverre Stefanussen; Bantle, Michael; Bamigbetan, Opeyemi Olayinka; Nekså, Petter (Chapter, 2019)
      Industrial processes like milk production often require simultaneous cooling and heating at temperature of 1 °C to 10 °C and 90 °C to 120 °C, respectively. High temperature heat pumps (HTHP) with natural working fluids are ...

    • Thermal Energy Storage with PCM for Refrigerated Sea Water System of Fishing Vessels 

      Saeed, Muhammad Zahid; Widell, Kristina Norne; Hafner, Armin; Svendsen, Eirik Starheim; Nordtvedt, Tom Ståle (Peer reviewed; Journal article, 2021)
      This paper investigates thermal storage integration with the refrigerated seawater (RSW) system of a fishing vessel. Four different scenarios were investigated, including ice in tanks, two design modifications in chilling ...
