A comparative study to investigate two configurations of a two-stage evaporator in a CO2 heat pump chiller
Hazarika, Mihir Mouchum; Hafner, Armin; Bengsch, Jan (Chapter; Peer reviewed, 2023)This study is carried out to investigate the performance of a CO2 heat pump chiller that provides heating and cooling simultaneously. For heating applications, hot water is produced at 90°C; while for cooling applications, ... -
Dimensioning and techno-economic-assessment of thermal energy storages in the food processing industry using energy load profiles
Bengsch, Jan; Svendsen, Eirik Starheim; Galteland, Olav; Widell, Kristina Marianne Norne; Selvnes, Håkon; Sevault, Alexis Gerard Edouard (Science et technique du froid;, Chapter; Peer reviewed, 2023)The food industry is a major consumer of electrical energy, which is required for cooling, freezing, drying and heating. Due to the production characteristics, high load peaks often occur in food processing. This leads not ... -
Integrated CO2 refrigeration and heat pump system for a dairy plant: Energy analysis and potential for cold thermal energy storage
Selvnes, Håkon; Jenssen, Sigmund; Sevault, Alexis Gerard Edouard; Bengsch, Jan; Widell, Kristina Marianne Norne; Ahrens, Marcel Ulrich; Ren, Shuai; Hafner, Armin (Chapter, 2023)Dairy processing is considered very energy-intensive due to significant thermal demands for both cooling and heating at different temperature levels. Conventional dairy plants have separate systems for supplying the various ... -
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 (Science et technique du froid;202-4, Chapter; Peer reviewed, 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; Peer reviewed, 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 ... -
Investigation and analysis of a CO2 heat pump chiller with novel two-stage evaporator
Bengsch, Jan; Hazarika, Mihir Mouchum; Hafner, Armin; Widell, Kristina Marianne Norne (Chapter, 2023)This study was carried out to investigate the performance of a transcritical CO2 heat pump chiller that provides heating and cooling simultaneously. There are several applications where such CO2 systems are implemented, ...
