• 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, ...
    • 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 (Science et technique du froid;, Chapter; Peer reviewed, 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 ...
    • 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 ...
