Résumé
The electrochemical looping heat pump (ELHP) is a novel thermodynamic cycle that incorporates a reverse fuel cell to achieve working fluid compression in the liquid state. Previous studies conducted by the authors demonstrated numerically the operation of the cycle in cooling mode and obtained performance improvements up to 20% with respect to conventional vapor compression cycle (VC) systems. In this paper, the cycle analysis has been extended to investigate heating mode operation. The primary focus of the study was the development of a working fluid screening process to determine suitable working fluid pairs while meeting low-GWP requirements. It was found that the developed screening process can be used to effectively control the cycle and the temperature of the fuel cell. Two working fluid pairs are identified, Isopropanol/Acetone and Ethanol/Acetaldehyde that yield COP improvements for heating compared to the best performing VC heat pump cycle (R290) of 21.8% and 13.5%, respectively. These working fluid pairs were selected from a wide number of hydrogenation/dehydrogenation reactions. It was discovered that these two working substance pairs are also the best performing in cooling mode. Finally, future research directions for this novel technology are identified.
