Summary

Air conditioning, space heating, and refrigeration account for nearly 40% of the primary energy use in the U.S. residential and commercial buildings. To reduce energy consumption, the development of highly efficient heat pumping technologies will play an indispensable role. The chemical looping heat pump (CLHP) system has shown 20% to 30% performance improvements relative to current vapor compression technologies. However, the results were mostly based on a simplified form of thermodynamic models, which necessitates experimental investigations and a deep understanding of the behavior of a non-ideal CLHP cycle. In this study, electrochemical cell materials and system performance of the CLHP cycle were evaluated based on the combination of component models and experimental results. The overpotential of the electrochemical cell was analyzed and coupled with a cycle model to understand the non-ideal behaviors of the cooling mode and the performance of the CLHP system. Lastly, the result of this study was compared with the previous analysis to discuss the impact of chemical kinetics on the CLHP cycle.
