Application of a Novel Two-Stage Evaporator in Air-Conditioning Applications
Köster, Lukas (Master thesis, 2023)Det foreliggende arbeidet undersøker anvendelsen av en ny totrinns fordamper i kombinasjon med et avansert hydronisk delsystem for å dekke luftkondisjoneringsbehov. Den foreslåtte systemarkitekturen består av en totrinns ... -
Calculating emission savings at electric construction sites
Kogstad, Jenny; Gyland, Kristine (Bachelor thesis, 2023)Norge har satt seg et mål om å ha en utslippsfri byggebransje innen 2030. For at dette skal være mulig er det nødvendig å finne en alternativ energikilde for å drifte byggeplassene. Aneo Build har en løsning der de leverer ... -
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, ... -
Experimental investigation on integrated two-stage evaporators for CO2 heat-pump chillers
Hafner, Armin; Hazarika, Mihir Mouchum; Lechi, Federico; Zorzin, Alvaro; Pardiñas, Ángel Á.; Banasiak, Krzysztof (Chapter, 2022)In this experimental study the performance of novel compact evaporator configuration was investigated. What makes this evaporator configuration unique is the integration of a gravity-fed/ self-circulation evaporator loop ... -
Experimental Study on the Integration of a Novel Two-Stage Evaporator in a CO2 Heat Pump Chiller
Hafsås, Johan (Master thesis, 2023)I denne masteroppgaven er det blitt utført eksperimentelle forsøk på en ny totrinns fordamper integrert i et transkritisk CO2-kjøleanlegg. Motivet for forsøkene er å se på muligheten for å forbedre energieffektiviteten i ... -
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 analysis of a CO2-ice heat pump
Söylemez, Engin; ERB, Kevin; Schubert, Maike; Gerber, Raphael; Carbonell, Daniel; Hazarika, Mihir Mouchum; Hafner, Armin (Chapter, 2023) -
Role of receiver on the performance of a transcritical CO2 based air-conditioning unit with single-stage and two-stage expansion
Hazarika, Mihir Mouchum; Ramgopal, Maddali; Bhattacharyya, Souvik; Doménech, Rodrigo Llopis (Peer reviewed; Journal article, 2021)Theoretical and experimental studies are carried out on a transcritical CO2 based air-conditioning unit. Two configurations– a system with single-stage expansion (SSE) and a system with two-stage expansion (TSE) have been ... -
Two-stage evaporator for R744 heat pumps using greywater as heat source
Pardiñas, Ángel Á.; Kauko, Hanne Laura Pauliina; Hazarika, Mihir Mouchum; Selvnes, Håkon; Banasiak, Krzysztof; Hafner, Armin (Peer reviewed; Journal article, 2023)Heat pumps are pinpointed as a key technology in decarbonizing buildings' heat supply, which is currently dominated by fossil-fuel based systems. To minimize the environmental impact of heat pumps over their lifetime, ...
