Two adsorption systems are considered: zeolite-water and activated carbon-methanol, both consisting of two 'uniform temperature' adsorbent beds operating with internal heat recovery by a heat carrier circuit. Regarding the zeolite-water system, the performance obtained with a new adsorbent bed, with good heat transfer properties, is compared with a traditional tube and fin exchanger embedded with zeolite pellets. The performances were calculated by using a dynamic model developed and validated previously. Results show that the system based on the new adsorber has a higher specific power and the same Coefficient of Performance. Results of simulation for adsorbers consisting of finned tube heat exchangers and utilising the activated carbon-methanol pair are also presented.

Abstract
Two adsorption systems are considered: zeolite-water and activated carbon-methanol, both consisting of two 'uniform temperature' adsorbent beds operating with internal heat recovery by a heat carrier circuit. Regarding the zeolite-water system, the performance obtained with a new adsorbent bed, with good heat transfer properties, is compared with a traditional tube and fin exchanger embedded with zeolite pellets. The performances were calculated by using a dynamic model developed and validated previously. Results show that the system based on the new adsorber has a higher specific power and the same Coefficient of Performance. Results of simulation for adsorbers consisting of finned tube heat exchangers and utilising the activated carbon-methanol pair are also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
