    • Attaining a higher flexibility degree in CO2 compressor racks 

      Álvarez Pardiñas, Ángel; Contiero, Luca; Hafner, Armin; Banasiak, Krzysztof; Larsen, Lars F.S. (Science et technique du froid;, Chapter, 2020)
      CO2 compressor racks have shown their suitability for commercial and industrial refrigeration systems at any location and climate. Even if some references state that CO2 units can compete in capital cost with any other ...

    • Experimental and numerical investigation of a transcritical CO2 air/water reversible heat pump: analysis of domestic hot water production 

      Tosato, Giacomo; Artuso, Paolo; Minetto, Silvia; Rossetti, Antonio; Allouche, Yosr; Banasiak, Krzysztof (Science et technique du froid;, Chapter, 2020)
      As a natural refrigerant, carbon dioxide is safe, economic and environmentally sustainable and can be successfully utilized in heat pump and refrigeration systems operating according to transcritical cycles. This paper ...

    • Field data of CO2 integrated refrigeration, heating and cooling systems for supermarkets 

      Tosato, Giacomo; Minetto, Silvia; Rossetti, Antonio; Hafner, Armin; Schlemminger, Christian; Girotto, Sergio (Science et technique du froid;, Chapter, 2020)
      The EU H2020 project MultiPACK has given the opportunity of installing three state-of-the art CO2 systems for supermarkets in South Europe, able to supply all the required thermal energy needs of the site, i.e. refrigeration, ...

    • Heat pump/chiller system for centralized kitchens in India 

      Singh, Simarpreet; Hafner, Armin; Banasiak, Krzysztof; Seshadri, Satyanarayanan; Maiya, Prakash; Smitt, Silje Marie; Gabrielii, Cecilia H (Science et technique du froid;, Chapter, 2020)
      A heat pump unit using CO2 as working fluid is designed to meet not only a part of the heating demand in the centralised kitchen at The Akshaya Patra Foundation, Bengaluru, India, but also the entire cooling demand to ...

    • Non-equilibrium approach in simulations of the R744 flow through the motive nozzle of the two-phase ejector 

      Bodys, Jakub; Smolka, Jacek; Palacz, Michał; Haida, Michal; Banasiak, Krzysztof (Science et technique du froid;, Chapter, 2020)
      The ejector technology for R744 systems was continuously improved over the last two decades in the area of control and design processes. The latter should be related with a significant interest on modelling approaches ...

    • Solar heat recovery system using CO2 as working fluid 

      Yamasaki, Haruhiko; Wakimoto, Hiroyuki; Yamaguchi, Hiroshi; Nekså, Petter (Science et technique du froid;, Chapter, 2020)
      This article proposes a solar water heater system induced by natural convective flow using supercritical CO2 as a working fluid. The proposed solar water heater can produce thermal energy as hot water from solar thermal ...
