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, 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, ... -
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 (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 ... -
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, ... -
