    • An energy graph-based approach to fault diagnosis of a transcritical CO2 heat pump 

      Uren, Kenneth R.; Van Schoor, George; Van Eldik, Martin; De Bruin, Johannes J.A. (MDPI, 2020)
      The objective of this paper is to describe an energy-based approach to visualize, identify, and monitor faults that may occur in a water-to-water transcritical CO 2 heat pump system. A representation using energy attributes ...
    • An energy-based representation of a counter flow single phase heat exchanger 

      Smuts, Stefan Benjamin (North-West University (South Africa) , Potchefstroom Campus, 2016)
      Energy is a fundamental part of human civilisation and the expected rise in global energy demand is approximately 1.7% per annum until 2030. With limited fossil fuels available for energy generation, other ways of energy ...
