The present work aims at the thermodynamic analysis of adsorption heat transformers (AdHT) for waste heat upgrade. Two different AdHT configurations have been simulated, namely, with and without heat recovery between the adsorbent beds. Two different working pairs, namely, AQSOA Z02/water and activated carbon/ammonia have been compared, varying working boundary conditions and analyzing the effect of heat recovery. The results have demonstrated that the performance is highly dependent on the employed working pair and that the implementation of heat recovery strategy can even double the achievable thermodynamic performance.

Abstract
The present work aims at the thermodynamic analysis of adsorption heat transformers (AdHT) for waste heat upgrade. Two different AdHT configurations have been simulated, namely, with and without heat recovery between the adsorbent beds. Two different working pairs, namely, AQSOA Z02/water and activated carbon/ammonia have been compared, varying working boundary conditions and analyzing the effect of heat recovery. The results have demonstrated that the performance is highly dependent on the employed working pair and that the implementation of heat recovery strategy can even double the achievable thermodynamic performance.File in questo prodotto:
